Description
3 ~ 73164-27 DES CRIPTIOt~
This invention relates to an apparatus which permits guick removal of high capacity disk drive units from a receiving unit of a host computer system. The appalatus further provides quick, simple installation o the disk drive units into the computer system.
In order to provide greater flexibility in the ld operation of a computer system it is often desirable to incorporate several disk drive units into the system.
Further, many applications permit the disk drive unit to be removed or interchanged for reasons of data security, backup purposes or for expanding a system. While this , is a desirable feature, previous systems have required the comDuter operator to manually remove a number of connecting cables and to unscre~ two thumb nuts to release the disk drive unit from its mountinq in the host computer system.
Also in previous designs an occasional misalignment of ribbon cable connectors during installation of the disk drive unit improperly connected the drive unit and or damaged pins on the disk drive controller. Further, extended cable lengths used in these systems could result in some data validity problems.
The invention relates to a disk drive information storage system wherein one or more disk drive carrier modules are detachably coupled with a receiving unit.
The invention provides a disk drive information o storage system comprising a receiving unit having an electrical connector fitting secured thereon for the transmission of control and data signals, a disk drive carrier module for detachable coupling with said receiving unit, and having an electrical connector 3c secured in fixed relation therewith for mating with the electrical connector fitting of said receiving unit, - 2- 1~3~J
said receiving unit and said disk drive carrier module having cooperating positioning means automatically operable to position said carrier module in a final assembled position in relation to the receiving unit 5 with said electric connector of said carrier module in mating relation to the electrical connector fitting of said receiving unit.
The invention further provides a disk drive information storage system of the foregoing type, with 10 the carrier module having a carrier handle disposed for convenient carrying of the carrier module, and said cooperating positioning means providing for interengagement of the carrier module with the receiving unit solely by manipulation of said carrier module, and ~-~ thereafter automatically guiding said carrier module into said final assembled position as manual insertion force is applied to said carrier handle.
The invention further provides in a disk drive information storage system, a receiving unit for the 20 transmission of signals for the control of a disk drive, and a disk drive carrier module containing a disk drive and constructed for detachable coupling with said receiving unit to form a disk drive system, said receiving unit having a receptacle arranged to receive said carrier module and having carrier module guide means for guiding said carrier module during its insertion into said receptacle along an insertion path, said receiving unit and said carrier module having cooperating electrical connectors which are 30 interconnected by movement toward each and said guide means constraining said carrier module such that the cooperating electric connectors automatically interconnect with each other as the carrier module is inserted into said receptacle.
- ~ 1333~5 The invention also provides in a disk drive information storage system, a receiving unit for the transmission of signals for the control of a disk drive, and a disk drive carrier module for containing a disk 5 drive, and for detachable coupling with said receiving unit to form a complete disk drive system, said carrier module having first and second mounting lug means for effecting an interengagement of the carrier module with the receiving unit, said receiving unit having first 10 retainer means for receiving said first lug means with the carrier module in a tilted orientation while accommoditing a pivotable movement of the carrier module about said first retaining means toward a fully assembled position, and second latching tyl~e retainer means aligned with the second lug means in the tilted orientation of the carrier module such that the second lug means are automatically latched by the second retainer means as the carrier module is pivoted about the first retainer means into the fully assembled 20 position, said lug means and said retainer means being automatically operable to secure said carrier module in said fully asssembled position solely by manipulation of said data module as a whole.
still further the invention provides in a disk drive information storage system as previously described, a disk drive carrier module of size to receive any of a plurality of disk drive units having respective different mounting hole requirements, and said disk drive carrier module having mounting means 3~) therein with patterns of mounting holes for selectively mounting any one of said plurality of disk drive units.
The present invention is directed to a disk drive carrier module which is quick and simple to remove froqn a host computer system and which can be quickly and 35 accurately ~einstalled in the system. A quick release ~ 4 ~ 1333505 arrangement for the disk drive module eliminates all manual insertions or extractions of connecting cables and automatically insures accurate positioning of the electrical connectors during final assembly of the disk 5 drive module into the host computer system. This automatic positioning arrangement preferably provides support for two disk drive carrier modules.
Each module includes a carrier assembly to which a disk drive unit is mounted. The carrier assembly has an 10 electrical connector member secured therewith and aligned with respect to a path of movement of the carrier module into its final installed operating position in the host computer system. Ribbon cableS
interconnect the disk drive unit with the electrical 15 connector .
Each carrier module is mounted in the computer system in operative relation to a receiving unit having an interconnect board. The interconnect board serves to accurately support an electrical connector fitting which 20 is connected to various computer system components in order to establish the desired power, data and control signal transmission paths as required. Each of the receiving units includes a guide mechanism which constrains the disk drive carrier module during its 25 final movement into operating position such that the electrical connectors are automatically aligned and interconnected.
In one embodiment, after engagement of one end of a carrier assembly with a receptacle of the receiving 30 unit, the second end of the carrier assembly is brought into a final assembled position by a downward force which separates latching members of one or more latching assemblies whereby mounting lugs at the second end of the carrier assembly are moved downward into engagement 35 with cradling supports of the receiving unit ~ 5 ~ 133350~
receptacle. When the mounting lugs are fully seated in the supports the latching members are spring biased back to their normal latching position to positively secure the second end of the carrier assembly. Further, the 5 electrical connector carried by the carrier assembly is automatically connected to a receiving electrical connector fitting to interconnect the electric circuit components as the mounting lugs are forced downward into the cradling supports. In a second embodiment, after 10 initial interengagement and alignment of a carrier module with a recess or receptacle of the receiving unit, the carrier module is inserted longitudinally via precision guidance devices into its final assembled and electrically interconnected condition, and automatically 5 1 atched i n i ts oper ati ng pos i tion.
During removal of a disk drive carrier module from the computer system, a handle of the carrier assembly is manually engaged and the force applied to the handle automatically effects disengagement of all electrical 20 connections during removal of the carrier module from i ts receptacl e.
It is therefore an object of this invention to provide a quick release disk drive carrier module which eliminates all manual insertions or extractionS of 2s electrical cables normally associated with installing or removing a disk drive from a computer system.
It is another object of this invention to provide a disk drive system which provides automatic electrical connections when the disk drive is installed in a 30 computer system.
It is yet another object of this invention to provide a cooperating latching and positioning arrangement which provides quick and accurate installation of a disk drive module in a computer system - 6 ~ 1 333~05 and which arrangement provides autanatic electrical connections to the disk drive with its installation.
It is f urther object of this invention to provide an arrangement for retaining a disk drive carrier module 5 in a computer system which is autanatically electrically releasable solely in response to manual forces applied to the carrier module.
Other objects features and advantages of this invention will be readily apparent from the following 10 description of preferred embodiments thereof, taken in conjunction with the accanpanying drawings, although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT~
Fig. 1 shows a disk drive module ln providing storage for data on a magnetic storage disk in a high capacity disk drive unit 11, such as a Winchester unit or the like. The disk drive module 10 includes a disk drive carrier assembly 12 which provides a mounting hole arrangement which is capable of accepting virtually any 5 1/4" hard disk drive as well as some floppy disk drives. The module lo is supported on a receiving unit - 1333~05 -- ~3 --which includes a base unit 13 and forms a fixed member in a host computer system 15. Preferably, the receiving unit of the computer system includes a second base unit 13a providing a receptacle for a second disk drive 5 module lOa (shown in phantom in Fig. 2). The second fixed base unit 13a is also fixedly secured within wall enclosures of the system 15.
Each carrier assembly such as assembly 12 of the module 10 comprises a removable carrier frame 17 having a bottom plate 18; a pair of side walls 19 and 20; an outer end wall 21 and an inner end wall 22. The inner wall extends above adjacent side walls 19 and 20 and is provided with a carrier handle opening 23, Fig. 3, whereby the inner end of the carrier frame may be 15 grasped by the computer operator for installation or removal of the module f rom the receiving unit of the computer system 15.
An access opening 2~, Fig. 3, is provided in the bottom plate 18, adjacent the inner side wall 22 and 20 having an "Eurocard" type electrical connector 26 mounted to the carrier frame 17 immediately above and aligned with the access opening. A pair of clamping fixtures 27 and 28 retain the connector 26 in a precise rigid position relative to the carrier frame 17. The 25 clamping fixtures 27 and 28 are provided with a retaining channel 30 to support opposed extended end portions 31 of the connector 26. As best seen in Fig. 5 the clamping fixtures are secured against the end wall 22 by bolts 32 threaded into nuts 33. The nuts 33 form 30 a unified portion of retaining plates 34 and 35 which are adapted to retain the end portions 31 of the connector in the channels 30. Thus it will be seen that the clamping fixtures together with the retaining plates 34 and 35 and the end wall 22 f ixedly position the 35 connector 2~ in a precise orientation. As best seen in - 9 1333~05 Figs. 4 and 5 an insulating material 36 is interposed between the clamping fixtures and the end wall 22.
Connecting pins 37, extending upward fran the electrical connector 26 serve as attachment means for a 5 terminal end of ribbon cables 3~ and 39 which provide electrical communication with the disk drive unit 11.
Each carrier assembly is additionally provided with an inner and outer pair of mounting lugs 40 and 41. The mounting lugs are substantially identical and affixed to 10 opposite ends of the side walls 19 and 20 by means of machine screws threaded into nuts 40a which are recessed into exterior surfaces of the mounting lugs as shown in Fig. 3.
Referring to Figs. 1 and 4 it can be seen that the 15 fixed base units 13 and 13a are fastened down to a base plate 42 of the computer system 15 by means of screws 43. Further an interconnect board 44 is positioned between inner ends of the base units 13 and 13a and is attached thereto by means of nut and screw connections 23 45- Adjacent each of these points of interconnection, electrical connector fittings ~0 and 51 are accurately positioned and secured by means of screws fasteners or the li ke.
Electrical communication lines 52 and 53 extend 25 fran the fittings 50 and 51 respectively to related computer system components as required. Herein, the lines 52 and 53 are shown as ribbon connector cables, connected to a hard disk controller board 55, although various other electrical communication arrangements may 30 be utilized in such a system, such as printed circuits or canbinations of printed circuits and short ribbon ca bl e j umpe r s .
As best seen in Figs. 2, 3, 6 and 7 each fixed base unit 13 and 13a includes a pair of guide and retaining 35 brackets 60, at a location remote f rom the connector - 10- 1333~05 f ittings, and a pair of positive latching devices 61 positioned at predetermined locations adjacent the connector fittings. The guide and retaining brackets 60 comprise upturned side portions 62 of the base units 5 with plastic insert members 63 bolted thereon to provide a guiding and retaining function for the mounting lugs 41 of the modules as will be described hereafter.
Each of the latching devices 61 includes an upturned inner side portion 65 of the base unit having an upwardly diverging recess 66 formed therein with a semi-circular seat portion 67. The seat portions are adapted to cradle the mounting lugs 40. Each latching device 61 f urther includes a pair of latching or clamping jaws 68 pivotally supported on studs 69 affixed 15 to the inner side portion 65 and equally spaced, horizontally from the seat portion 67. A second stud 70, hori20ntally spaced from each stud 69, cooperates with an arcuate guide slot 71 to limit pivotal movement of the jaws 68. Further, a torsion spring 73 is 20 provided to urge each of the jaws 68 to an upright latching position, wherein a latching surface 74 on complementary pairs of jaws complete a substantial encirclement of the mounting lugs 40. The seat portion 67 provides the encirclement about the lower portion of 25 the lugs 40.
Nuts 64 retain the clamping jaws 68 and the springs 73 on their respective mounting studs 69 and 70. An additional stud 75 and nut 76 carried on the upper end of the jaws 68, serve to retain an extended leg of the 30 torsion spring 73 in a biasing orientation. With the mounting lugs 41 at the outer end of the module supported in the brackets 60 and the mounting lugs 40 at the inner end secured in the latching devices 61 the disk drive module 10 is in a desired operating position 35 relative to the base unit 13 and at the same time the 1333~0~
connector fitting ~0 is electrically engaged with connecting pins 37a of the electrical connector 2~, extending downward through the access opening 25.
The Eurocard type connector in addition to 5 transmittinq control and data signals provides self diagnostic circuits to indicator lights 78, Fig. 1, which signal that a proper electrical connection has been made, that the required voltage is available and which of the two disk drive modules has been selected 10 for operation.
To quickly and easily remove a disk drive module 10 fran a base unit 13 of the computer system 15, power is switched off and the drive unit is allowed to spin down. When the disks have stopped rotating, the 15 computer operator grasps the carrier handle 23 and pulls upward causing the mounting lugs 40 to cam open the clamping jaws 68 as seen at the left in Fig. 2. The lugs move upward between the jaws in a pivotal motion about the mounting lugs 41 which are still retained in 20 the brackets 60. During this pivotal motion the electrical connections are severed.
Thereafter, as the lugs 40 clear the latching devices 61, the lugs 41 are moved longitudinally along a guide surface 80 of the insert members 63 and out of the 25 retaining pockets or open slots 81 def ined therein. The entire disk drive module 10 is now free to be removed.
When installing a disk drive module 10 in the computer system 15, the operator positions the carrier assembly 12 between the pair of guide and retaining 30 brackets 50 with the mounting lugs 41 angled downward to rest on the guide surfaces 80. Thereafter the module is moved longitudinally along the surface 80 and into engagement with the retaining pockets 81. Then the inner end of the carrier assembly is pivoted downward 35 about the axis of the mounting lugs 41 and into contact - 12- 1333~i0~) with upper camming faces 82 of the clamping jaws 68.
The mounting lugs 40 cam open the jaws 68 against the bias of the springs 73 to pass downward into the seat portions 67 of the latching devices 61. At this point 5 the latching surfaces 74 of the jaws 68 will have enclosed about the upper portions of the lugs 40 to positively secure the disk drive module 10 in a precise operating position. The camming faces 82 further insure proper orientation of the carrier assembly 12 relative 10 to the fixed base and the connector fitting during the final pivotal movement of installation. This insures that a proper electrical connection will be made without damaging the connecting pins 37a. Thus all the required electrical transmission paths are automatically 15 completed with installation of the disk drive module 10.
Although the teachings of my invention have herein been discussed with reference to a specific embodiment, it is to be understood that these are by way of illustration only and that variations and modifications 20 may be effected. Accordingly, it should be understood that I wish to embody within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of my contribution to the art.
2; Fig. 8 shows disk drive modules 10-1 and 10-2 which generally correspond with the disk drive module 10 of Fig. 1 in providing storage for data or other information, for example by means of magnetic storage disks in respective high capacity disk drive units, such 30 as Winchester units or the like. Respective disk drive units are indicated at 11-1 and 11-2 in Fig. 8. ~ach disk drive module includes a disk drive carrier assembly such as 12-1 which provides a mounting hole arrangement capable of accepting virtually any 5 1/4 inch hard disk 35 drive as well as some floppy disk drives.
- 13- 1333~05 The disk drive carrier modules ln-l and 10-2 are shown as being insertable into respective side-by-side receptacles such as lol of a receiving unit 102. The receiving unit includes a chassis 103 on which various system components are mounted, and a cooperating top cover 104. By way of example, the receiving unit 102 may serve as an information storage expansion system for addition to a computer system which includes a central processing unit with integrated floppy disk storage devices, and further auxiliary devices such as a keyboard and monitor, and a printer.
Each carrier assembly such as 12-1 comprises a bottom wall 108, Figs. 9 and 10, side walls 109, 110, Fig. 8, a rear wall 111, Figs. 9 and lo, and a front wall 112- The front wall 112 is provided with a carrier handle 114 which may be grasped by the operator in transporting the carrier module, and in inserting and removing the carrier module with respect to its receptacle in the receiving unit.
An aperture in the rear wall 111 allows the mating end of an electrical connector 115 of each carrier module to project rearwardly for automatic interconnection with cooperating connector fittings 116 of t he r ece i vi ng un i t .
The particular disk drive such as unit 11-1 which is mounted in each respective carrier module is electrically connected with the connector 115 by means of ribbon cables such as 118 and 119 and releasable connector terminal means corresponding to that shown in Fig. 3 for ribbon cables 38 and 39. It will be noted that ribbon cables 118 and llq are of minimum length and extend between the rear end of the particular disk drive unit such as 11-1 and the adjoining connector 115. The ribbon cables 118 and 119 extend between parts all of which are secured with the carrier module, so that the - 14 - 1333~i0~i ribbon cables 118 and 119 need not include extra length to ac~ ~Ate a disassembly operation or the like.
Similarly, the electrical wiring such as indicated at 121, 122 and 123 in Fig. 8 which leads to the 5 electrical eonnector fitting 116 of the receiving unit, extends between parts which are all secured with the chassis 103. All electrical connections between the receiving unit and the carrier modules are completed autanatically as the carrier modules are inserted into 3 their receptacles, and there is no need for manual grasping of ribbon cables and manipulation thereof to complete the electrical connections.
As best seen in Fig. lo, the receiving unit has latching members such as 124 which are pivotally mounted as at 125 so that a latching nose 126 projecting fran member 124 engages a cam face 127 at the rear of the carrier module side wall 109 as the carrier module is inserted into its receptacle. A compression spring 128 acts to urge the latching member 124 in a clockwise direction as viewed in Fig. 10, while allowing the latching member to pivot in a counter-clockwise direction about pivot 125 in response to cam face 127.
The carrier module side wall 109 has a recess 12q into which the latching nose 126 pivots as the carrier module reaches its final assembled position. By way of example, the latching members such as 124 may be of rigid synthetic (plastic) material such as nylon.
A solenoid 130 has an armature extension 131 pivotally connected with the latch member 124 at 132.
In deenergized condition of solenoid 130, the spring 128 holds a rear edge face of nose 126 in eonfronting relation to a rear wall of recess 129 so as to lock the carrier module in its receptacle. Upon energization of solenoid 130, however, the armature extension 131 is retracted against the action of spring 128, to lift nose 126 to position 126', Fig. 10, clear of recess 129 , thereby allowing manual removal of the carrier module from its receptacle. With solenoid 130 energized, the handle 114 can be grasped and the carrier module 5 removed, simultaneously effecting disconnection of the electrical connectors such as 115, 116, Fig. 8.
Referring to Fig. 9, a front cover 140 is shown which is secured to the front edge of chassis 103. The cover 140 has an access opening 141 which is defined by 10 inturned flanges such as 14t)a and 14nb which tend to support and guide the carrier modules 10-1 and ln-2 as they are being manually positioned for insertion into the respective receptacles. The front surface of the cover 140 has a sloping front panel configuration at lS 140c so that flange 140a at the lower edge of opening 141 is more accessible for initallly supporting the rear edges of the carrier modules during their alignment with the receptacles.
The chassis 103 includes an upturned front flange 20 103a, Fig. 9, which has a height corresponding to the vertical height of the front cover 140 and has rectangular apertures such as 142 formed therein corresponding to the cross sectional dimensions of the respective carrier modules. As can be seen in Fig. 9, 25 the plate defining front wall 112 of each carrier module abuts against a margin of the respective receiving aperture defined bY flange lO~a when the carrier module has been f ully inserted into its receptacle.
The sides and rear of the carrier module 30 receptacles are provided by an open enclosure frame 150, F ig. 9 . A rear wall 151 of the enclosure f rame 150 has a lower outturned flange 151a which is f astened to chassis 103. The enclosure frame 150 also provides side walls 152, 153, Fig. 8, having outturned flange portions - l6- 1333~5 at the upper margins thereof such as indicated at 15~a and 152b, Fig. ~, which carry solenoid mounting plates 154 at each side of the enclosure frame.
As seen in Fig. 10, the top edge of each side wall 5 of the enclosure frame has a relatively shallow notch at 155 and a relatively deeper notch at 1s6. The shallow notch at 15s accommodates movement of the nose portion 126 of latch member 124 to its latching position when the notch 129 reaches the position shown in Fig. 10.
The deeper notch 156, Fig. 10, accommodates a mechanical sensor element 158 of a microswitch assembly 159. As shown in Fig. 8, the sensor element 158 projects through notch 156 and into receptacle 101 until such time as the carrier module 12-1 deflects the sensor lS element as the carrier module moves into the receptacle. Thus, when microswitch assembly 159 is in non-actuated condition, the associated receptacle does not have a fully inserted carrier module.
As seen in Figs. 11 and 1~, the rear wall 151 of 20 the enclosure f rame includes rectangular openings 151 which receive the forward portions of the respective connector fittings 116. By way of example, each fitting 116 may have a pair of alignment holes 162, 163 and two rows of electrical contact sockets 164. By way of 25 example, in addition to alignment pins 165, 166, Fig.
11, there may be sixty pins 167, Fig. 12, on each connector 115 for fitting into respective sockets 164 of each connector fitting 116. As shown in Fig. 12, the alignment pins such as 165 have tapered tip ends, and 30 the alignment holes have frustoconical entrance portions 162a for correcting any slight misalignment before the contact pins 167 reach their respective contact sockets 164.
The precise guidance of the carrier modules such as 35 12-1, Fig. 11, is carried out by guide means including 133350~
supporting guide rails shown at 171, 172 and 173 of synthetic ~plastic) material such as nylon. The side rails 171 and 173 provide smooth broad support surfaces 171a, 173a having a relatively substantial width 5 dimension, for example one-half inch (1. 27 centimeter). The center guide rail has a center ridge 172a separating support surfaces 172b and 172c each of which may have the same width as support surfaces 171a and 173a.
To complete the low friction precision guidance for the carrier modules, abrasion resistant lateral guide strips 181 and 182, Fig. 11, are secured to the inner sides of side walls 152 and 153 of the enclosure frame.
Suitable manually actuated switches may be located at the front cover 140 at 183 and 184 for manual depression to energi ze the respective solenoids 130 until such time as the associated disk drive carrier module has been retracted from its receptacle to a position such as indicated for carrier module 10-1 in Fig. 8. At this time, sensor element 158 is cleared, allowing it to return to its non-actuated position whereby the energizing circuit for the associated solenoid 130 may be interrupted to deenergize the sol eno i d .
In loading a disk drive carrier module, the handle 114 may be grasped with one hand while the other hand guides the carrier module into the front access opening 141, Fig. 9, in alignment with the desired receptacle such as lol, Fig. 8. The extended lower flange 140a and the sloping front panel 140C with side flanges such as 140b facilitate the initial alignment of the carrier module and its engagement with the supporting surfaces such as 171a, 172b, Fig. 11. The rectangular apertures such as 142, Fig. 9, in the upstanding chassis flange 103a insure that the carrier modules are smoothly guided 133350~
into their respective receptacles with lateral guidance thereafter being effected by means of the center guide ridge 172a, Fig. 11, in conjunction with the outer lateral guide strips 181 and 182. The carrier modules 5 have a rounded rear lower margin at 185 to further facilitate insertion into the respective receptacles.
The guidance means 171-173 and 181-182, Fig. 11, are disposed with a precision such that the alignment pins such as 165, Fig. 12, are reliably interengaged with the receiving alignment holes 162, 163; the interengagement of the ~lignment or pilot means 162, 163, 164, 165 in turn insures the precise alignment of the electrical contact pins 167 of connectors 115 with the contact sockets 164 of the fixed connector fittings 116 as the carrier modules complete their insertion movem en t . T hus the ca r r i er mod ul e el ect r i c ci r cui ts ar e reliably automatically interconnected with the circuits of the receiving unit simply by pushing the carrier modules into their receptacles.
zo The cam means 127, Fig. 10, on each carrier module automatically lift the latch members 124 to the position indicated at 124' as the carrier modules approach the f ully inserted position; thereafter springs such as 128, Fig. 10, press the latches 124 into latching engagement with notches 129 of the carrier modules to latch the carrier modules in the fully assembled position as shown in solid outline in Fig. 10.
I t will be apparent that many modif ications and variations may be made without department from the scope of the teachings and concepts of the present invention.
This invention relates to an apparatus which permits guick removal of high capacity disk drive units from a receiving unit of a host computer system. The appalatus further provides quick, simple installation o the disk drive units into the computer system.
In order to provide greater flexibility in the ld operation of a computer system it is often desirable to incorporate several disk drive units into the system.
Further, many applications permit the disk drive unit to be removed or interchanged for reasons of data security, backup purposes or for expanding a system. While this , is a desirable feature, previous systems have required the comDuter operator to manually remove a number of connecting cables and to unscre~ two thumb nuts to release the disk drive unit from its mountinq in the host computer system.
Also in previous designs an occasional misalignment of ribbon cable connectors during installation of the disk drive unit improperly connected the drive unit and or damaged pins on the disk drive controller. Further, extended cable lengths used in these systems could result in some data validity problems.
The invention relates to a disk drive information storage system wherein one or more disk drive carrier modules are detachably coupled with a receiving unit.
The invention provides a disk drive information o storage system comprising a receiving unit having an electrical connector fitting secured thereon for the transmission of control and data signals, a disk drive carrier module for detachable coupling with said receiving unit, and having an electrical connector 3c secured in fixed relation therewith for mating with the electrical connector fitting of said receiving unit, - 2- 1~3~J
said receiving unit and said disk drive carrier module having cooperating positioning means automatically operable to position said carrier module in a final assembled position in relation to the receiving unit 5 with said electric connector of said carrier module in mating relation to the electrical connector fitting of said receiving unit.
The invention further provides a disk drive information storage system of the foregoing type, with 10 the carrier module having a carrier handle disposed for convenient carrying of the carrier module, and said cooperating positioning means providing for interengagement of the carrier module with the receiving unit solely by manipulation of said carrier module, and ~-~ thereafter automatically guiding said carrier module into said final assembled position as manual insertion force is applied to said carrier handle.
The invention further provides in a disk drive information storage system, a receiving unit for the 20 transmission of signals for the control of a disk drive, and a disk drive carrier module containing a disk drive and constructed for detachable coupling with said receiving unit to form a disk drive system, said receiving unit having a receptacle arranged to receive said carrier module and having carrier module guide means for guiding said carrier module during its insertion into said receptacle along an insertion path, said receiving unit and said carrier module having cooperating electrical connectors which are 30 interconnected by movement toward each and said guide means constraining said carrier module such that the cooperating electric connectors automatically interconnect with each other as the carrier module is inserted into said receptacle.
- ~ 1333~5 The invention also provides in a disk drive information storage system, a receiving unit for the transmission of signals for the control of a disk drive, and a disk drive carrier module for containing a disk 5 drive, and for detachable coupling with said receiving unit to form a complete disk drive system, said carrier module having first and second mounting lug means for effecting an interengagement of the carrier module with the receiving unit, said receiving unit having first 10 retainer means for receiving said first lug means with the carrier module in a tilted orientation while accommoditing a pivotable movement of the carrier module about said first retaining means toward a fully assembled position, and second latching tyl~e retainer means aligned with the second lug means in the tilted orientation of the carrier module such that the second lug means are automatically latched by the second retainer means as the carrier module is pivoted about the first retainer means into the fully assembled 20 position, said lug means and said retainer means being automatically operable to secure said carrier module in said fully asssembled position solely by manipulation of said data module as a whole.
still further the invention provides in a disk drive information storage system as previously described, a disk drive carrier module of size to receive any of a plurality of disk drive units having respective different mounting hole requirements, and said disk drive carrier module having mounting means 3~) therein with patterns of mounting holes for selectively mounting any one of said plurality of disk drive units.
The present invention is directed to a disk drive carrier module which is quick and simple to remove froqn a host computer system and which can be quickly and 35 accurately ~einstalled in the system. A quick release ~ 4 ~ 1333505 arrangement for the disk drive module eliminates all manual insertions or extractions of connecting cables and automatically insures accurate positioning of the electrical connectors during final assembly of the disk 5 drive module into the host computer system. This automatic positioning arrangement preferably provides support for two disk drive carrier modules.
Each module includes a carrier assembly to which a disk drive unit is mounted. The carrier assembly has an 10 electrical connector member secured therewith and aligned with respect to a path of movement of the carrier module into its final installed operating position in the host computer system. Ribbon cableS
interconnect the disk drive unit with the electrical 15 connector .
Each carrier module is mounted in the computer system in operative relation to a receiving unit having an interconnect board. The interconnect board serves to accurately support an electrical connector fitting which 20 is connected to various computer system components in order to establish the desired power, data and control signal transmission paths as required. Each of the receiving units includes a guide mechanism which constrains the disk drive carrier module during its 25 final movement into operating position such that the electrical connectors are automatically aligned and interconnected.
In one embodiment, after engagement of one end of a carrier assembly with a receptacle of the receiving 30 unit, the second end of the carrier assembly is brought into a final assembled position by a downward force which separates latching members of one or more latching assemblies whereby mounting lugs at the second end of the carrier assembly are moved downward into engagement 35 with cradling supports of the receiving unit ~ 5 ~ 133350~
receptacle. When the mounting lugs are fully seated in the supports the latching members are spring biased back to their normal latching position to positively secure the second end of the carrier assembly. Further, the 5 electrical connector carried by the carrier assembly is automatically connected to a receiving electrical connector fitting to interconnect the electric circuit components as the mounting lugs are forced downward into the cradling supports. In a second embodiment, after 10 initial interengagement and alignment of a carrier module with a recess or receptacle of the receiving unit, the carrier module is inserted longitudinally via precision guidance devices into its final assembled and electrically interconnected condition, and automatically 5 1 atched i n i ts oper ati ng pos i tion.
During removal of a disk drive carrier module from the computer system, a handle of the carrier assembly is manually engaged and the force applied to the handle automatically effects disengagement of all electrical 20 connections during removal of the carrier module from i ts receptacl e.
It is therefore an object of this invention to provide a quick release disk drive carrier module which eliminates all manual insertions or extractionS of 2s electrical cables normally associated with installing or removing a disk drive from a computer system.
It is another object of this invention to provide a disk drive system which provides automatic electrical connections when the disk drive is installed in a 30 computer system.
It is yet another object of this invention to provide a cooperating latching and positioning arrangement which provides quick and accurate installation of a disk drive module in a computer system - 6 ~ 1 333~05 and which arrangement provides autanatic electrical connections to the disk drive with its installation.
It is f urther object of this invention to provide an arrangement for retaining a disk drive carrier module 5 in a computer system which is autanatically electrically releasable solely in response to manual forces applied to the carrier module.
Other objects features and advantages of this invention will be readily apparent from the following 10 description of preferred embodiments thereof, taken in conjunction with the accanpanying drawings, although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT~
Fig. 1 shows a disk drive module ln providing storage for data on a magnetic storage disk in a high capacity disk drive unit 11, such as a Winchester unit or the like. The disk drive module 10 includes a disk drive carrier assembly 12 which provides a mounting hole arrangement which is capable of accepting virtually any 5 1/4" hard disk drive as well as some floppy disk drives. The module lo is supported on a receiving unit - 1333~05 -- ~3 --which includes a base unit 13 and forms a fixed member in a host computer system 15. Preferably, the receiving unit of the computer system includes a second base unit 13a providing a receptacle for a second disk drive 5 module lOa (shown in phantom in Fig. 2). The second fixed base unit 13a is also fixedly secured within wall enclosures of the system 15.
Each carrier assembly such as assembly 12 of the module 10 comprises a removable carrier frame 17 having a bottom plate 18; a pair of side walls 19 and 20; an outer end wall 21 and an inner end wall 22. The inner wall extends above adjacent side walls 19 and 20 and is provided with a carrier handle opening 23, Fig. 3, whereby the inner end of the carrier frame may be 15 grasped by the computer operator for installation or removal of the module f rom the receiving unit of the computer system 15.
An access opening 2~, Fig. 3, is provided in the bottom plate 18, adjacent the inner side wall 22 and 20 having an "Eurocard" type electrical connector 26 mounted to the carrier frame 17 immediately above and aligned with the access opening. A pair of clamping fixtures 27 and 28 retain the connector 26 in a precise rigid position relative to the carrier frame 17. The 25 clamping fixtures 27 and 28 are provided with a retaining channel 30 to support opposed extended end portions 31 of the connector 26. As best seen in Fig. 5 the clamping fixtures are secured against the end wall 22 by bolts 32 threaded into nuts 33. The nuts 33 form 30 a unified portion of retaining plates 34 and 35 which are adapted to retain the end portions 31 of the connector in the channels 30. Thus it will be seen that the clamping fixtures together with the retaining plates 34 and 35 and the end wall 22 f ixedly position the 35 connector 2~ in a precise orientation. As best seen in - 9 1333~05 Figs. 4 and 5 an insulating material 36 is interposed between the clamping fixtures and the end wall 22.
Connecting pins 37, extending upward fran the electrical connector 26 serve as attachment means for a 5 terminal end of ribbon cables 3~ and 39 which provide electrical communication with the disk drive unit 11.
Each carrier assembly is additionally provided with an inner and outer pair of mounting lugs 40 and 41. The mounting lugs are substantially identical and affixed to 10 opposite ends of the side walls 19 and 20 by means of machine screws threaded into nuts 40a which are recessed into exterior surfaces of the mounting lugs as shown in Fig. 3.
Referring to Figs. 1 and 4 it can be seen that the 15 fixed base units 13 and 13a are fastened down to a base plate 42 of the computer system 15 by means of screws 43. Further an interconnect board 44 is positioned between inner ends of the base units 13 and 13a and is attached thereto by means of nut and screw connections 23 45- Adjacent each of these points of interconnection, electrical connector fittings ~0 and 51 are accurately positioned and secured by means of screws fasteners or the li ke.
Electrical communication lines 52 and 53 extend 25 fran the fittings 50 and 51 respectively to related computer system components as required. Herein, the lines 52 and 53 are shown as ribbon connector cables, connected to a hard disk controller board 55, although various other electrical communication arrangements may 30 be utilized in such a system, such as printed circuits or canbinations of printed circuits and short ribbon ca bl e j umpe r s .
As best seen in Figs. 2, 3, 6 and 7 each fixed base unit 13 and 13a includes a pair of guide and retaining 35 brackets 60, at a location remote f rom the connector - 10- 1333~05 f ittings, and a pair of positive latching devices 61 positioned at predetermined locations adjacent the connector fittings. The guide and retaining brackets 60 comprise upturned side portions 62 of the base units 5 with plastic insert members 63 bolted thereon to provide a guiding and retaining function for the mounting lugs 41 of the modules as will be described hereafter.
Each of the latching devices 61 includes an upturned inner side portion 65 of the base unit having an upwardly diverging recess 66 formed therein with a semi-circular seat portion 67. The seat portions are adapted to cradle the mounting lugs 40. Each latching device 61 f urther includes a pair of latching or clamping jaws 68 pivotally supported on studs 69 affixed 15 to the inner side portion 65 and equally spaced, horizontally from the seat portion 67. A second stud 70, hori20ntally spaced from each stud 69, cooperates with an arcuate guide slot 71 to limit pivotal movement of the jaws 68. Further, a torsion spring 73 is 20 provided to urge each of the jaws 68 to an upright latching position, wherein a latching surface 74 on complementary pairs of jaws complete a substantial encirclement of the mounting lugs 40. The seat portion 67 provides the encirclement about the lower portion of 25 the lugs 40.
Nuts 64 retain the clamping jaws 68 and the springs 73 on their respective mounting studs 69 and 70. An additional stud 75 and nut 76 carried on the upper end of the jaws 68, serve to retain an extended leg of the 30 torsion spring 73 in a biasing orientation. With the mounting lugs 41 at the outer end of the module supported in the brackets 60 and the mounting lugs 40 at the inner end secured in the latching devices 61 the disk drive module 10 is in a desired operating position 35 relative to the base unit 13 and at the same time the 1333~0~
connector fitting ~0 is electrically engaged with connecting pins 37a of the electrical connector 2~, extending downward through the access opening 25.
The Eurocard type connector in addition to 5 transmittinq control and data signals provides self diagnostic circuits to indicator lights 78, Fig. 1, which signal that a proper electrical connection has been made, that the required voltage is available and which of the two disk drive modules has been selected 10 for operation.
To quickly and easily remove a disk drive module 10 fran a base unit 13 of the computer system 15, power is switched off and the drive unit is allowed to spin down. When the disks have stopped rotating, the 15 computer operator grasps the carrier handle 23 and pulls upward causing the mounting lugs 40 to cam open the clamping jaws 68 as seen at the left in Fig. 2. The lugs move upward between the jaws in a pivotal motion about the mounting lugs 41 which are still retained in 20 the brackets 60. During this pivotal motion the electrical connections are severed.
Thereafter, as the lugs 40 clear the latching devices 61, the lugs 41 are moved longitudinally along a guide surface 80 of the insert members 63 and out of the 25 retaining pockets or open slots 81 def ined therein. The entire disk drive module 10 is now free to be removed.
When installing a disk drive module 10 in the computer system 15, the operator positions the carrier assembly 12 between the pair of guide and retaining 30 brackets 50 with the mounting lugs 41 angled downward to rest on the guide surfaces 80. Thereafter the module is moved longitudinally along the surface 80 and into engagement with the retaining pockets 81. Then the inner end of the carrier assembly is pivoted downward 35 about the axis of the mounting lugs 41 and into contact - 12- 1333~i0~) with upper camming faces 82 of the clamping jaws 68.
The mounting lugs 40 cam open the jaws 68 against the bias of the springs 73 to pass downward into the seat portions 67 of the latching devices 61. At this point 5 the latching surfaces 74 of the jaws 68 will have enclosed about the upper portions of the lugs 40 to positively secure the disk drive module 10 in a precise operating position. The camming faces 82 further insure proper orientation of the carrier assembly 12 relative 10 to the fixed base and the connector fitting during the final pivotal movement of installation. This insures that a proper electrical connection will be made without damaging the connecting pins 37a. Thus all the required electrical transmission paths are automatically 15 completed with installation of the disk drive module 10.
Although the teachings of my invention have herein been discussed with reference to a specific embodiment, it is to be understood that these are by way of illustration only and that variations and modifications 20 may be effected. Accordingly, it should be understood that I wish to embody within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of my contribution to the art.
2; Fig. 8 shows disk drive modules 10-1 and 10-2 which generally correspond with the disk drive module 10 of Fig. 1 in providing storage for data or other information, for example by means of magnetic storage disks in respective high capacity disk drive units, such 30 as Winchester units or the like. Respective disk drive units are indicated at 11-1 and 11-2 in Fig. 8. ~ach disk drive module includes a disk drive carrier assembly such as 12-1 which provides a mounting hole arrangement capable of accepting virtually any 5 1/4 inch hard disk 35 drive as well as some floppy disk drives.
- 13- 1333~05 The disk drive carrier modules ln-l and 10-2 are shown as being insertable into respective side-by-side receptacles such as lol of a receiving unit 102. The receiving unit includes a chassis 103 on which various system components are mounted, and a cooperating top cover 104. By way of example, the receiving unit 102 may serve as an information storage expansion system for addition to a computer system which includes a central processing unit with integrated floppy disk storage devices, and further auxiliary devices such as a keyboard and monitor, and a printer.
Each carrier assembly such as 12-1 comprises a bottom wall 108, Figs. 9 and 10, side walls 109, 110, Fig. 8, a rear wall 111, Figs. 9 and lo, and a front wall 112- The front wall 112 is provided with a carrier handle 114 which may be grasped by the operator in transporting the carrier module, and in inserting and removing the carrier module with respect to its receptacle in the receiving unit.
An aperture in the rear wall 111 allows the mating end of an electrical connector 115 of each carrier module to project rearwardly for automatic interconnection with cooperating connector fittings 116 of t he r ece i vi ng un i t .
The particular disk drive such as unit 11-1 which is mounted in each respective carrier module is electrically connected with the connector 115 by means of ribbon cables such as 118 and 119 and releasable connector terminal means corresponding to that shown in Fig. 3 for ribbon cables 38 and 39. It will be noted that ribbon cables 118 and llq are of minimum length and extend between the rear end of the particular disk drive unit such as 11-1 and the adjoining connector 115. The ribbon cables 118 and 119 extend between parts all of which are secured with the carrier module, so that the - 14 - 1333~i0~i ribbon cables 118 and 119 need not include extra length to ac~ ~Ate a disassembly operation or the like.
Similarly, the electrical wiring such as indicated at 121, 122 and 123 in Fig. 8 which leads to the 5 electrical eonnector fitting 116 of the receiving unit, extends between parts which are all secured with the chassis 103. All electrical connections between the receiving unit and the carrier modules are completed autanatically as the carrier modules are inserted into 3 their receptacles, and there is no need for manual grasping of ribbon cables and manipulation thereof to complete the electrical connections.
As best seen in Fig. lo, the receiving unit has latching members such as 124 which are pivotally mounted as at 125 so that a latching nose 126 projecting fran member 124 engages a cam face 127 at the rear of the carrier module side wall 109 as the carrier module is inserted into its receptacle. A compression spring 128 acts to urge the latching member 124 in a clockwise direction as viewed in Fig. 10, while allowing the latching member to pivot in a counter-clockwise direction about pivot 125 in response to cam face 127.
The carrier module side wall 109 has a recess 12q into which the latching nose 126 pivots as the carrier module reaches its final assembled position. By way of example, the latching members such as 124 may be of rigid synthetic (plastic) material such as nylon.
A solenoid 130 has an armature extension 131 pivotally connected with the latch member 124 at 132.
In deenergized condition of solenoid 130, the spring 128 holds a rear edge face of nose 126 in eonfronting relation to a rear wall of recess 129 so as to lock the carrier module in its receptacle. Upon energization of solenoid 130, however, the armature extension 131 is retracted against the action of spring 128, to lift nose 126 to position 126', Fig. 10, clear of recess 129 , thereby allowing manual removal of the carrier module from its receptacle. With solenoid 130 energized, the handle 114 can be grasped and the carrier module 5 removed, simultaneously effecting disconnection of the electrical connectors such as 115, 116, Fig. 8.
Referring to Fig. 9, a front cover 140 is shown which is secured to the front edge of chassis 103. The cover 140 has an access opening 141 which is defined by 10 inturned flanges such as 14t)a and 14nb which tend to support and guide the carrier modules 10-1 and ln-2 as they are being manually positioned for insertion into the respective receptacles. The front surface of the cover 140 has a sloping front panel configuration at lS 140c so that flange 140a at the lower edge of opening 141 is more accessible for initallly supporting the rear edges of the carrier modules during their alignment with the receptacles.
The chassis 103 includes an upturned front flange 20 103a, Fig. 9, which has a height corresponding to the vertical height of the front cover 140 and has rectangular apertures such as 142 formed therein corresponding to the cross sectional dimensions of the respective carrier modules. As can be seen in Fig. 9, 25 the plate defining front wall 112 of each carrier module abuts against a margin of the respective receiving aperture defined bY flange lO~a when the carrier module has been f ully inserted into its receptacle.
The sides and rear of the carrier module 30 receptacles are provided by an open enclosure frame 150, F ig. 9 . A rear wall 151 of the enclosure f rame 150 has a lower outturned flange 151a which is f astened to chassis 103. The enclosure frame 150 also provides side walls 152, 153, Fig. 8, having outturned flange portions - l6- 1333~5 at the upper margins thereof such as indicated at 15~a and 152b, Fig. ~, which carry solenoid mounting plates 154 at each side of the enclosure frame.
As seen in Fig. 10, the top edge of each side wall 5 of the enclosure frame has a relatively shallow notch at 155 and a relatively deeper notch at 1s6. The shallow notch at 15s accommodates movement of the nose portion 126 of latch member 124 to its latching position when the notch 129 reaches the position shown in Fig. 10.
The deeper notch 156, Fig. 10, accommodates a mechanical sensor element 158 of a microswitch assembly 159. As shown in Fig. 8, the sensor element 158 projects through notch 156 and into receptacle 101 until such time as the carrier module 12-1 deflects the sensor lS element as the carrier module moves into the receptacle. Thus, when microswitch assembly 159 is in non-actuated condition, the associated receptacle does not have a fully inserted carrier module.
As seen in Figs. 11 and 1~, the rear wall 151 of 20 the enclosure f rame includes rectangular openings 151 which receive the forward portions of the respective connector fittings 116. By way of example, each fitting 116 may have a pair of alignment holes 162, 163 and two rows of electrical contact sockets 164. By way of 25 example, in addition to alignment pins 165, 166, Fig.
11, there may be sixty pins 167, Fig. 12, on each connector 115 for fitting into respective sockets 164 of each connector fitting 116. As shown in Fig. 12, the alignment pins such as 165 have tapered tip ends, and 30 the alignment holes have frustoconical entrance portions 162a for correcting any slight misalignment before the contact pins 167 reach their respective contact sockets 164.
The precise guidance of the carrier modules such as 35 12-1, Fig. 11, is carried out by guide means including 133350~
supporting guide rails shown at 171, 172 and 173 of synthetic ~plastic) material such as nylon. The side rails 171 and 173 provide smooth broad support surfaces 171a, 173a having a relatively substantial width 5 dimension, for example one-half inch (1. 27 centimeter). The center guide rail has a center ridge 172a separating support surfaces 172b and 172c each of which may have the same width as support surfaces 171a and 173a.
To complete the low friction precision guidance for the carrier modules, abrasion resistant lateral guide strips 181 and 182, Fig. 11, are secured to the inner sides of side walls 152 and 153 of the enclosure frame.
Suitable manually actuated switches may be located at the front cover 140 at 183 and 184 for manual depression to energi ze the respective solenoids 130 until such time as the associated disk drive carrier module has been retracted from its receptacle to a position such as indicated for carrier module 10-1 in Fig. 8. At this time, sensor element 158 is cleared, allowing it to return to its non-actuated position whereby the energizing circuit for the associated solenoid 130 may be interrupted to deenergize the sol eno i d .
In loading a disk drive carrier module, the handle 114 may be grasped with one hand while the other hand guides the carrier module into the front access opening 141, Fig. 9, in alignment with the desired receptacle such as lol, Fig. 8. The extended lower flange 140a and the sloping front panel 140C with side flanges such as 140b facilitate the initial alignment of the carrier module and its engagement with the supporting surfaces such as 171a, 172b, Fig. 11. The rectangular apertures such as 142, Fig. 9, in the upstanding chassis flange 103a insure that the carrier modules are smoothly guided 133350~
