ART/1UP R JOHN A 92 15 vs the plug and jack;

Patented July 1, 1941 PATENT OFFICE CABLE CONNECTOR 7 Arthur R. John, Dayton, Ohio I Application March 12, 1940, Serial No. 323,563

3 Claims. (01. 173-328) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to a plug and jack for use in making an electrical coupling between one or more sets of wires in circuit.

The invention more particularly relates to electrical connectors in which the mating connector elements are housed and shielded within separate complementary metallic shield members.

It is an object of this invention to provide a sealed plug which may be readily assembled and disassembled without the use of special tools.

It is another object of this invention to provide a plug to which the cable wiring may be soldered prior to assembly.

It is another object of this invention to provide an electrical connector which is dustprooi. and dampproof and which can be assembled and disassembled without twisting of the cables.

It is another object of this invention to provide an electrical connector which not only permits ready inspection of the solder contacts but also permits circuit and continuity tests-with the plug in partially disassembled condition but opera-e.

tively connected with the associated equipment. It is a further object of this invention to profrom the rear end oi. the plug assembly; 7

Other objects of invention will become parent from the following description taken in connection with the accompanying drawing:

Figure 1 is an elevational view of the assembled plus and lack; v

Figure 2 is an exploded perspective view of Figure 3 is an elevational view of the inner sleeve member; I

Figure 4 is an end elevational view of the inner sleeve member showing the ferrule-receiving slot;

Figure 5 is an elevational view of'the ferrule;

Figure 6 is a cross-sectional view of the ferrule taken along the lines 6-6 of Figure 5'.

Referring to the drawing, the jack member is vide an assembly by which the cable wires and contact-sleeve retainercan be removed composed of housing I which contains male connector elements-referred to generally as 1 l1.

These connector elements are suitably separated by insulating material (not shown) and have soldered thereto the wires of the cable referred to generally as i8. Housing I is suitably fastened to plug housing 2 by collar 3, threaded to correspend with threads on housing i. Collar 3 is loosely carried by housing 2 between flange 2i and rib 22. Plug 4, formed of suitable insulating material, is adapted to retain connector elements generally referred to as 5. These connector elements have soldered thereto at one end thereof the individual wires of the cable IS. The other ends of the connector elements are split for irictionally receiving connector elements 5, and resiliently held together by coil spring 20. Sleeve 6 is formed with a tubular plug-receiving portion 8 and a longitudinal sectional portion 9 formed in the shape of a trough by cutting away part of the tube. This trough portion is somewhat longer than the plug 4, so that the plug can be removed therefrom with the wires soldered to the connectors without breaking the soldered connection. Plug 4 is suitably held in the tubular portion of sleeve 6 by set screw 1. Sleeve 6 also has an end plate member i0 having a radial slot Ii therein for laterallyslidably receiving a ferrule-i2, soldered to cable IS. The

ferrule is provided with straight side portions.

i3 which cooperate with the sides of slotii to prevent rotation of the ferrule when operatively positioned with respect to the sleeve 6." The ferrule is threaded at M to receive nut 15 which locks the sleeve to the housing and seals the cable-receiving opening i6 in the housing.

In disassembling e, device, starting with the from housing 1.. Since extended relative movement between collar '3 andhousing 2 is prevented parts as shown in Figure 1. collar 3 is unscrewed by flange 23- cooperating with flange 2i and rim 22, rotation of collar 3 initiates separation of connectors l7 and 5. Complete separation is eflected by pulling housing I away from the plug assembly. Nut i5 is then unscrewed and-housing 2 slid alo'ngcable i9, uncovering sleeve 6. screw 1 is. then removed from tubular portion 8 or sleeve 8, ferrule i2 slid laterally out of slot ii, and plug-4 slid longitudinally into space 9 of the sleeve 6. Contact plug 4, with the wires of the cable is soldered thereto, is then removable from inner sleeve 6' by lateral movement thereof.

When assembled, plug 4 is snugly received in and positioned by tubular portion 8 of sleeve 8. thereby firmly holding the connector-elements 5 in position when forced into engagement with.

tion, taken in connection with the accompanying drawing, is by way of illustration only, it being intended to limit the scope of the invention only by the appended claims.

I claim:

1. In a sealed cable connector of the type having a jack unit and a socket unit and means for sealingly connecting the units, one of the said units comprising: a housing having a cablereceiving opening therein, a connector plug, a connector-plug-positioning sleeve having a trough portion of greater length than said connector plug, a tubular connector-plug-receiving portion attached thereto at one end thereof and a radially slotted end portion attached to the other end thereof, a cable, a cable-receiving ferrule positioned in the slot of said end portion and received in said cable-receiving opening, and means for sealingly connecting said ferrule and cable to said housing.

2. In a cable connector, an assembly including:

a housing; a sleeve member having a tubularportion, a radially slotted end portion, and a trough portion therebetween; a contact-retain plug of less length than the length of said troug portion and operatively positioned in said tllbl lar portion; a cable; a cable-receiving ferrule non-rotatably received in the radial slot of said end portion; and means sealingly connecting said ferrule and cable to said housing.

3. In a cable connector, an assembly including a housing; a sleeve member received in salil housing, said sleeve member including a tubular portion, a radially slotted end portion, and a trough portion therebetween; a contact-retainer plug of less length than the length of said troughportion and operatively positioned in said tubule r: portion; a cable; and cable-carrying means receivable in the radial slot of said end portion for fastening said sleeve to said housing.

ARTHUR R. JOHN.
