Definitions
- the present disclosure relates to fiber optic data transmission, and more particularly to fiber optic cable connection systems.
- Fiber optic cables are widely used to transmit light signals for high speed data transmission.
- a fiber optic cable typically includes: (1) an optical fiber or optical fibers; (2) a buffer or buffers that surrounds the fiber or fibers; (3) a strength layer that surrounds the buffer or buffers; and (4) an outer jacket.
- Optical fibers function to carry optical signals.
- a typical optical fiber includes an inner core surrounded by a cladding that is covered by a coating.
- Buffers e.g., loose or tight buffer tubes
- Strength layers add mechanical strength to fiber optic cables to protect the internal optical fibers against stresses applied to the cables during installation and thereafter.
- Example strength layers include aramid yarn, steel and epoxy reinforced glass roving.
- Outer jackets provide protection against damage caused by crushing, abrasions, and other physical damage.
- Outer jackets also provide protection against chemical damage (e.g., ozone, alkali, acids).
- Fiber optic cable connection systems are used to facilitate connecting and disconnecting fiber optic cables in the field without requiring a splice.
- a typical fiber optic cable connection system for interconnecting two fiber optic cables includes fiber optic connectors mounted at the ends of the fiber optic cables, and an adapter for mechanically and optically coupling the fiber optic connectors together.
- Fiber optic connectors generally include ferrules that support the ends of the optical fibers of the fiber optic cables. The end faces of the ferrules are typically polished and are often angled.
- the adapter includes co-axially aligned ports (i.e., receptacles) for receiving the fiber optic connectors desired to be interconnected.
- the adapter includes an internal sleeve that receives and aligns the ferrules of the fiber optic connectors when the connectors are inserted within the ports of the adapter. With the ferrules and their associated fibers aligned within the sleeve of the adapter, a fiber optic signal can pass from one fiber to the next.
- the adapter also typically has a mechanical fastening arrangement (e.g., a snap-fit arrangement) for mechanically retaining the fiber optic connectors within the adapter.
- a mechanical fastening arrangement e.g., a snap-fit arrangement

- a plug portion 56 is defined at the distal end 52 and two tabs 58 are provided at the proximal end 54 .
- One of the tabs 58 is provided by the body 36 of the housing and the other of the tabs 58 is provided by the cover 41 of the housing 39 .
- the body 36 is depicted as a unitary molded piece (e.g., a molded plastic piece as shown at FIGS. 7-9 ) and the cover 41 is depicted as a separate unitary molded piece (e.g., a molded plastic piece as shown at FIGS. 7 , 10 and 11 ).
- a central passage 118 is defined through the interior of the connector housing 39 from the proximal end 54 to the distal end 52 .
- the central passage 118 has a distal portion 118 a defined through the plug portion 56 of the connector housing 39 and a proximal portion 118 b defined between the body 36 and the cover 41 .
- the proximal portion 118 b of the central passage 118 is defined in part by the body 36 and in part by the cover 41 . Removal of the cover 41 from the body 36 provides lateral access to the proximal portion 118 b of the central passage 118 .
- the distal portion 118 a of the passage 118 is defined entirely by the body 36 and extends through the plug portion 56 .
- the distal portion 118 a of the passage 118 has a distal end at the distal end 52 of the housing 39 and a proximal end adjacent the proximal portion 118 b of the passage 118 .
- the plug portion 56 of the first connector 32 is sized and shaped to fit within the first port 35 of the adapter 34 , as shown at FIGS. 3 , 17 and 19 .
- the distal end of the plug portion 56 preferably has a tapered configuration that mates or matches (e.g., nests, complements) with a tapered portion of a first plug receptacle 59 accessed from the first port 35 (see FIG. 17 ).
- the tapered configuration is defined by opposite surfaces (e.g., left and right surfaces 61 , 63 ) that converge as the surfaces extend along a central axis A 1 of the connector 32 in a distal direction.
- the end of the plug portion 56 is truncated. When the plug portion 56 is positioned within the first plug receptacle 59 , the surfaces 61 , 63 engage and are parallel to or generally parallel to angled surfaces 67 , 69 that define the first plug receptacle 59 .
- the latch 50 of the first connector 32 is provided at a top side of the plug portion 56 .
- the latch 50 has a cantilever arm 90 with a base end 81 that is integrally molded with the plug portion 56 .
- the arm 90 extends in a distal direction from the base end 81 to a free end 83 .
- a retention tab 51 is provided adjacent the free end 83 of the arm 90 .
- the retention tab 51 includes an inclined region 92 and a declined region 94 .
- the arm 90 is configured to flex as the plug portion 56 is inserted into the first port 35 of the adapter 34 , and to provide a snap-fit connection between the first connector 32 and the adapter 34 when the plug portion 56 is fully inserted into the first port 35 .
- retention tab 51 snaps within a latch notch 82 defined by the adapter 34 when the plug portion 56 is fully inserted in the first port 35 .
- the latch notch 82 is defined in part by a retention surface 96 .
- the arm 90 of the latch 50 When inserting the plug portion 56 into the first port 35 of the adapter 34 , the arm 90 of the latch 50 is flexed toward axis A 1 by adapter 34 as the inclined region 92 comes into contact with adapter 34 .
- Arm 90 is designed of a material capable of flexing when compressed, such as a plastic. Insertion of plug portion 56 into the port 35 continues until the inclined region 92 passes by the retention surface 96 of the notch 82 . After the inclined region 92 is entirely past the retention surface 96 , the declined region 94 comes into contact with surface 96 . A force generated by the flexing of arm 90 causes the retention tab 51 to raise as the declined region 94 proceeds past surface 96 .
- adapter 34 can be designed to retain some of the compression of arm 90 , if desired.
- One of the benefits of the latch mechanism is that it provides a force that inhibits removal of the first connector 32 from the first port 35 , such as to resist unintentional disengagement of the first connector 32 from the first port 35 .
- a force that inhibits removal of the first connector 32 from the first port 35 , such as to resist unintentional disengagement of the first connector 32 from the first port 35 .
- the declined region 94 comes into contact with the retention surface 96 of latch notch 82 .
- a force must be applied in a direction away from the first port 35 sufficient to cause the arm 90 to compress as declined region 94 is pulled back along surface 96 .
- the force required can be configured to be greater or lesser by adjusting the strength of the arm 90 , and also by adjusting the slope of declined region 94 .
- the snap-fit configuration of the latch 50 also provides a physical and audible indication that the first connector 32 has been fully inserted into the first port 35 .
- the inclined region 92 of the retention tab 51 has an angle of incline illustrated as A 2 and the declined region 94 of the retention tab 51 has an angle of decline illustrated as A 3 .
- angle A 2 is less than angle A 3 .
- the benefit of this is that the latch 50 will be easier to insert than it will be to remove, because the decreased angle of incline (A 2 ) will not present as much resistance to insertion as the increased angle of decline (A 3 ) will present to removal.
- angle A 3 is about double angle A 2 .
- angle A 2 is about equal to angle A 3 . It is recognized, however, than any angles may be formed for angles A 2 and A 3 .
- angles A 2 and A 3 are in a range from about 0 degrees to about 90 degrees, and preferably from 15 degrees to about 85 degrees. In another example, angle A 2 is in a range from about 15 degrees to about 45 degrees and angle A 3 is in a range from about 30 degrees to about 90 degrees.
- the inclined and declined regions 92 and 94 meet at a peak, having a height H 1 .
- the arm 90 extends a height H 2 above an adjacent portion of plug portion 56 .
- height H 1 is about equal to height H 2 .
- height H 2 is larger than height H 1 to ensure that latch 50 is not inhibited from movement by the adjacent portion of plug portion 56 .
- height H 2 can be less than height H 1 , so long as adequate space is provided to enable latch 50 to be appropriately inserted into notch 82 .
- angle A 3 can be about 90 degrees, such that the declined region 94 extends generally perpendicular to the arm 90 .
- the declined region 94 will not permit the latch 50 to be removed by the mere application of a force in a direction away from the port 35 .
- the latch 50 can be manually released, such as by manually depressing the latch 50 , such as through the notch 82 .
- the latch 50 can be depressed, for example, by inserting a narrow release tool through the notch 82 to depress the latch 50 .
- a button can be formed over the notch 82 .
- the button can include an arm that extends through the notch 82 , such that when the button is depressed, the arm depresses the latch 50 , enabling the first connector 32 to be removed from the first port 35 .
- the coupling nut 40 of the first connector 32 is adapted to provide a second connection mechanism for securing the first connector 32 to the adapter 34 .
- the coupling nut 40 can be threaded into corresponding threads provided within the first port 35 so as to provide a second connection with the adapter 34 .
- the coupling nut 40 provides a connection with the adapter 34 that has a substantially greater pull-out resistance from the pull-out resistance provided by the latch 50 .
- the coupling nut 40 retains the first connector 32 in the first port 35 even if a pull-out force of at least 100 pounds is applied to the first connector 32 .
- the coupling nut 40 of the first connector 32 includes a first region 180 and a second region 182 .
- the first region 180 includes a plurality of grooves 184 to facilitate grasping of the first region 180 , such as by a field technician or other user during connection or disconnection of the connector 32 with the adapter 34 .
- the grooves 184 are for example a plurality of longitudinally oriented grooves that enable a user to more easily rotate the coupling nut 40 .
- Turning of the coupling nut 40 enables a connection means of the second region 182 to engage or disengage with the adapter 34 .
- the second region 182 includes a connection means of exterior screw threads 75 adapted to mate with internal threads 76 provided within the first port 35 of the adapter 34 . In another embodiment, other connection means may also be used.
- the ferrule assembly 43 of the first connector 32 includes a ferrule 100 (e.g., a ceramic ferrule), a barrel 101 mounted on the ferrule 100 , a spring 102 and a spring holder 104 .
- the ferrule assembly 43 is loaded into the first connector 32 while the cover 41 is removed from the main body 36 .
- the ferrule 100 is positioned in the distal portion 118 a of the central passage 118 by inserting the ferrule 100 through the proximal end of the distal portion 118 a. As so inserted, the barrel 101 abuts against a shoulder 103 located within the plug portion 56 (see FIGS. 17 and 19 ).
- the spring 102 is then inserted into the distal portion 118 a behind the ferrule 100 . Thereafter, the spring holder 104 is loaded into a pocket 114 (see FIGS. 8-11 ) of the main body 36 at a location behind the spring 102 such that the spring 102 is captured within the distal portion 118 a between the barrel 101 and the spring holder 104 . In this manner, the ferrule 100 is spring biased in a distal direction.
- the proximal portion of the connector housing 39 is configured to facilitate providing a secure connection between the first cable 20 and the first connector 32 .
- the proximal portion 118 b of the central passage 118 is sized to receive the buffer tube 220 of the first cable 20 .
- Strength member receivers 120 e.g., channels, passages, grooves, etc.
- the body 36 includes alignment openings 116 that receive corresponding alignment pins 117 of the cover 41 to insure that that cover 41 properly aligns with the body 36 when mounted thereto.
- the connector housing 39 further includes bleed openings 122 for allowing adhesive to bleed from the interior of the housing 39 when the cover 41 is mounted to the body 36 .
- the interior of the housing 39 further includes structure for improving adhesion between adhesive and the interior of the housing.
- the interior of the housing includes a plurality of slots 123 for improving the adhesion characteristics of the interior surface of the housing 39 .
- Other adhesion improving structures include knurling, surface roughening, or other structures.
- the exterior of the connector housing 39 includes a circumferential groove 112 for mounting the sealing member 49 .
- the exterior of the housing 39 also includes circumferential shoulders 124 and 125 (see FIG. 7 ), against which the crimp band 38 can abut after assembly of the connector, and a circumferential shoulder 113 (shown in FIGS. 8 and 9 ).
- a circumferential recessed portion 128 is defined on the outside of the tabs 58 .
- Retaining teeth 130 are located on the inside of the tabs 58 .
- the end of the fiber optic cable 20 is prepared using a stripping process.
- the outer jacket 226 is stripped away to expose the strength members 224 and the buffer tube 220 .
- a portion of the buffer tube 220 is cut away to expose the optical fiber 222 .
- the boot 42 is slid onto the end of fiber optic cable 20 , followed by the sealing tube 106 (e.g., a heat shrink tube or heat shrink tape/wrap), the coupling nut 40 , and the crimp band 38 .

Description
- This application is a continuation of U.S. patent application Ser. No. 11/657,404, filed Jan. 24, 2007, which application is hereby incorporated by reference in its entirety.
- The present disclosure relates to fiber optic data transmission, and more particularly to fiber optic cable connection systems.
- Fiber optic cables are widely used to transmit light signals for high speed data transmission. A fiber optic cable typically includes: (1) an optical fiber or optical fibers; (2) a buffer or buffers that surrounds the fiber or fibers; (3) a strength layer that surrounds the buffer or buffers; and (4) an outer jacket. Optical fibers function to carry optical signals. A typical optical fiber includes an inner core surrounded by a cladding that is covered by a coating. Buffers (e.g., loose or tight buffer tubes) typically function to surround and protect coated optical fibers. Strength layers add mechanical strength to fiber optic cables to protect the internal optical fibers against stresses applied to the cables during installation and thereafter. Example strength layers include aramid yarn, steel and epoxy reinforced glass roving. Outer jackets provide protection against damage caused by crushing, abrasions, and other physical damage. Outer jackets also provide protection against chemical damage (e.g., ozone, alkali, acids).
- Fiber optic cable connection systems are used to facilitate connecting and disconnecting fiber optic cables in the field without requiring a splice. A typical fiber optic cable connection system for interconnecting two fiber optic cables includes fiber optic connectors mounted at the ends of the fiber optic cables, and an adapter for mechanically and optically coupling the fiber optic connectors together. Fiber optic connectors generally include ferrules that support the ends of the optical fibers of the fiber optic cables. The end faces of the ferrules are typically polished and are often angled. The adapter includes co-axially aligned ports (i.e., receptacles) for receiving the fiber optic connectors desired to be interconnected. The adapter includes an internal sleeve that receives and aligns the ferrules of the fiber optic connectors when the connectors are inserted within the ports of the adapter. With the ferrules and their associated fibers aligned within the sleeve of the adapter, a fiber optic signal can pass from one fiber to the next. The adapter also typically has a mechanical fastening arrangement (e.g., a snap-fit arrangement) for mechanically retaining the fiber optic connectors within the adapter. One example of an existing fiber optic connection system is described in U.S. Pat. Nos. 6,579,014, 6,648,520, and 6,899,467.
- One aspect of the present disclosure relates to a fiber optic adapter having a dual fastening arrangement for securing a fiber optic connector in the fiber optic adapter.
- Another aspect of the present disclosure relates to a fiber optic adapter that is adapted to provide relatively high fiber optic circuit densities at an enclosure.
- A further aspect of the present disclosure relates to a fiber optic adapter having a tapered interface adapted to complement a corresponding tapered interface of a fiber optic connector.
- A variety of additional inventive aspects will be set forth in the description that follows. The inventive aspects can relate to individual features and to combinations of features. It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.

FIGS. 1-5 depict a fiberoptic connection system 30 in accordance with the principles of the present disclosure for optically connecting a first fiber optic cable 20 (seeFIG. 4 ) to a second fiber optic cable 22 (seeFIG. 4 ). The fiberoptic connection system 30 includes a fiberoptic adapter 34, a first fiberoptic connector 32 terminating thefirst cable 20, and a second fiber optic connector 33 (shown atFIG. 3 ) terminating the second fiberoptic cable 22. Theadapter 34 is depicted mounted to an enclosure 19 (shown schematically atFIG. 4 ). Theadapter 34 includes afirst port 35 for receiving thefirst connector 32 and asecond port 37 for receiving thesecond connector 33. Thefirst cable 20 is optically coupled to thesecond cable 22 when theconnectors respective ports adapter 34. - As shown at
FIG. 4 , thefirst cable 20 is an external cable (e.g., an outside plant cable located outside the enclosure 19) and thesecond cable 22 is located inside theenclosure 19. In such an embodiment, thefirst cable 20 cable is adapted to carry an optical signal to theenclosure 19 and the fiberoptic connection system 30 allows the signal to be transferred from thefirst cable 20 to thesecond cable 22. - The
cables FIG. 5 , thefirst cable 20 includes acentral buffer tube 220 containing at least oneoptical fiber 222.Strength members 224 are positioned on opposite sides of thecentral buffer tube 220. Thestrength members 224 and the buffer tube are positioned within anouter jacket 226 of thecable 20. - The
enclosure 19 can include a wide variety of optical enclosures/housings (e.g., drop terminals, pedestals, network interface devices, fiber distribution hubs, splice enclosures, optical network terminals, etc.). In one embodiment,adapters 34 can be mounted to a drop terminal of the type disclosed at U.S. patent application Ser. No. 11/075,847, entitled Fiber Access Terminal, filed on Mar. 8, 2005, and that is hereby incorporated by reference in its entirety. For such embodiments, thecable 20 can be a drop cable routed to a subscriber premises and thecable 22 can be a connectorized fiber from a stub cable that is routed from the drop terminal to a fiber break-out location of a fiber distribution cable. Example fiber break-out configurations are disclosed at U.S. patent application Ser. No. 11/491,336, entitled Fiber Optic Cable Breakout Configuration with Retention Block, filed on Jul. 21, 2006, and that is hereby incorporated by reference in its entirety. In another embodiment, one or more of the adapters can be mounted to a network interface device of the type disclosed at U.S. application Ser. No. 11/607,676, entitled Network Interface Device, filed on Dec. 1, 2006, and that is hereby incorporated by reference in its entirety. In such an embodiment, thefirst cable 20 can include a drop cable and thecable 22 can include a connectorized cable/fiber positioned within the network interface device. Alternatively, fiberoptic connection system 30 can also be used without an enclosure (e.g., the adapter can be panel mounted). - In the depicted embodiment, the
first connector 32 and theadapter 34 are hardened or ruggedized. By hardened or ruggedized, it is meant thatfirst connector 32 and theadapter 34 are adapted for outside environmental use. For example, thefirst connector 32 and theadapter 34 can include environmental seals for preventing moisture/water intrusion. Also, it is preferred for thefirst connector 32 to be able to withstand a 100 pound axial pull-out force when coupled to theadapter 34. Thesecond connector 33 can be a conventional fiber optic connector such as a Subscription Channel (“SC”) connector. One example of an SC connector is illustrated and described in US. Pat. No. 5,317,663, that is hereby incorporated by reference in its entirety. - Referring to
FIGS. 5 and 7 , thefirst connector 32 includes aconnector housing 39 including amain body 36 and acover 41. Theconnector housing 39 extends from adistal end 52 to a proximal end 54 (distal and proximal are defined with respect to the connection withfiber optic cable 20 for connector 32). Aferrule assembly 43 mounts adjacent thedistal end 52 of theconnector housing 39 and astrain relief boot 42 mounts adjacent theproximal end 54 of theconnector housing 39. A sealing member 49 (e.g., an o-ring seal) mounts around a periphery/exterior of theconnector housing 39. The sealingmember 49 is adapted for providing a seal between theconnector housing 39 and theadapter 34 when thefirst connector 32 is plugged into thefirst port 35 of theadapter 34. Thefirst connector 32 also includes acrimp band 38 that mounts over themain body 36 and thecover 41, and a sealingtube 106 that seals the interface between thecable 20 and theconnector housing 39. Thecrimp band 38 assists in retaining thecover 41 on themain body 36 and also assists in securing thestrength members 224 of thecable 20 in place between thecover 41 and themain body 36. Thefirst connector 32 also includes first and second fastening structures for retaining (i.e., connecting, securing, etc.) thefirst connector 32 within thefirst port 35 of theadapter 34. For example, thefirst connector 32 can include a latch 50 (see FIGS. 3, 7, 14 and 15) for mechanically interlocking with theadapter 34 when thefirst connector 32 is inserted in thefirst port 35. Thefirst connector 32 also includes acoupling nut 40 adapted to thread into theadapter 34 to retain thefirst connector 32 within thefirst port 35 of theadapter 34. - The
connector housing 39 of theconnector 32 extends fromdistal end 52 toproximal end 54. Aplug portion 56 is defined at thedistal end 52 and twotabs 58 are provided at theproximal end 54. One of thetabs 58 is provided by thebody 36 of the housing and the other of thetabs 58 is provided by thecover 41 of thehousing 39. Thebody 36 is depicted as a unitary molded piece (e.g., a molded plastic piece as shown atFIGS. 7-9 ) and thecover 41 is depicted as a separate unitary molded piece (e.g., a molded plastic piece as shown atFIGS. 7 , 10 and 11). Acentral passage 118 is defined through the interior of theconnector housing 39 from theproximal end 54 to thedistal end 52. Thecentral passage 118 has adistal portion 118 a defined through theplug portion 56 of theconnector housing 39 and aproximal portion 118 b defined between thebody 36 and thecover 41. Theproximal portion 118 b of thecentral passage 118 is defined in part by thebody 36 and in part by thecover 41. Removal of thecover 41 from thebody 36 provides lateral access to theproximal portion 118 b of thecentral passage 118. Thedistal portion 118 a of thepassage 118 is defined entirely by thebody 36 and extends through theplug portion 56. Thedistal portion 118 a of thepassage 118 has a distal end at thedistal end 52 of thehousing 39 and a proximal end adjacent theproximal portion 118 b of thepassage 118. - The
plug portion 56 of thefirst connector 32 is sized and shaped to fit within thefirst port 35 of theadapter 34, as shown atFIGS. 3 , 17 and 19. The distal end of theplug portion 56 preferably has a tapered configuration that mates or matches (e.g., nests, complements) with a tapered portion of afirst plug receptacle 59 accessed from the first port 35 (seeFIG. 17 ). As shown atFIG. 17 , the tapered configuration is defined by opposite surfaces (e.g., left andright surfaces 61, 63) that converge as the surfaces extend along a central axis A1 of theconnector 32 in a distal direction. The end of theplug portion 56 is truncated. When theplug portion 56 is positioned within thefirst plug receptacle 59, thesurfaces angled surfaces first plug receptacle 59. - As shown at
FIGS. 14 and 15 , thelatch 50 of thefirst connector 32 is provided at a top side of theplug portion 56. Thelatch 50 has acantilever arm 90 with abase end 81 that is integrally molded with theplug portion 56. Thearm 90 extends in a distal direction from thebase end 81 to afree end 83. Aretention tab 51 is provided adjacent thefree end 83 of thearm 90. Theretention tab 51 includes aninclined region 92 and a declinedregion 94. Thearm 90 is configured to flex as theplug portion 56 is inserted into thefirst port 35 of theadapter 34, and to provide a snap-fit connection between thefirst connector 32 and theadapter 34 when theplug portion 56 is fully inserted into thefirst port 35. For example, as shown atFIG. 14 ,retention tab 51 snaps within alatch notch 82 defined by theadapter 34 when theplug portion 56 is fully inserted in thefirst port 35. Thelatch notch 82 is defined in part by aretention surface 96. - When inserting the
plug portion 56 into thefirst port 35 of theadapter 34, thearm 90 of thelatch 50 is flexed toward axis A1 byadapter 34 as theinclined region 92 comes into contact withadapter 34.Arm 90 is designed of a material capable of flexing when compressed, such as a plastic. Insertion ofplug portion 56 into theport 35 continues until theinclined region 92 passes by theretention surface 96 of thenotch 82. After theinclined region 92 is entirely past theretention surface 96, the declinedregion 94 comes into contact withsurface 96. A force generated by the flexing ofarm 90 causes theretention tab 51 to raise as the declinedregion 94 proceeds pastsurface 96. Insertion continues until declinedregion 94 is completely, or almost completely, past theretention surface 96 of thenotch 82. At this point, compression of thearm 90 byadapter 34 is released, such that thearm 90 returns to its uncompressed state. Alternatively, theadapter 34 can be designed to retain some of the compression ofarm 90, if desired. - One of the benefits of the latch mechanism is that it provides a force that inhibits removal of the
first connector 32 from thefirst port 35, such as to resist unintentional disengagement of thefirst connector 32 from thefirst port 35. For example, if thefirst connector 32 begins to move in a direction away from thefirst port 35, the declinedregion 94 comes into contact with theretention surface 96 oflatch notch 82. At this point, in order for thefirst connector 32 to be removed from thefirst port 35, a force must be applied in a direction away from thefirst port 35 sufficient to cause thearm 90 to compress as declinedregion 94 is pulled back alongsurface 96. The force required can be configured to be greater or lesser by adjusting the strength of thearm 90, and also by adjusting the slope of declinedregion 94. The snap-fit configuration of thelatch 50 also provides a physical and audible indication that thefirst connector 32 has been fully inserted into thefirst port 35. - The
inclined region 92 of theretention tab 51 has an angle of incline illustrated as A2 and the declinedregion 94 of theretention tab 51 has an angle of decline illustrated as A3. In the illustrated embodiment, angle A2 is less than angle A3. The benefit of this is that thelatch 50 will be easier to insert than it will be to remove, because the decreased angle of incline (A2) will not present as much resistance to insertion as the increased angle of decline (A3) will present to removal. In one example, angle A3 is about double angle A2. In another example, angle A2 is about equal to angle A3. It is recognized, however, than any angles may be formed for angles A2 and A3. In one example, angles A2 and A3 are in a range from about 0 degrees to about 90 degrees, and preferably from 15 degrees to about 85 degrees. In another example, angle A2 is in a range from about 15 degrees to about 45 degrees and angle A3 is in a range from about 30 degrees to about 90 degrees. - The inclined and declined
regions arm 90 extends a height H2 above an adjacent portion ofplug portion 56. In one example, height H1 is about equal to height H2. Alternatively, height H2 is larger than height H1 to ensure thatlatch 50 is not inhibited from movement by the adjacent portion ofplug portion 56. Alternatively, height H2 can be less than height H1, so long as adequate space is provided to enablelatch 50 to be appropriately inserted intonotch 82. - In another example, angle A3 can be about 90 degrees, such that the declined
region 94 extends generally perpendicular to thearm 90. In this example, the declinedregion 94 will not permit thelatch 50 to be removed by the mere application of a force in a direction away from theport 35. Rather, thelatch 50 can be manually released, such as by manually depressing thelatch 50, such as through thenotch 82. Thelatch 50 can be depressed, for example, by inserting a narrow release tool through thenotch 82 to depress thelatch 50. Alternatively, a button can be formed over thenotch 82. The button can include an arm that extends through thenotch 82, such that when the button is depressed, the arm depresses thelatch 50, enabling thefirst connector 32 to be removed from thefirst port 35. - The
coupling nut 40 of thefirst connector 32 is adapted to provide a second connection mechanism for securing thefirst connector 32 to theadapter 34. After thelatch 50 has interlocked with theadapter 34, thecoupling nut 40 can be threaded into corresponding threads provided within thefirst port 35 so as to provide a second connection with theadapter 34. Thecoupling nut 40 provides a connection with theadapter 34 that has a substantially greater pull-out resistance from the pull-out resistance provided by thelatch 50. In one example embodiment, thecoupling nut 40 retains thefirst connector 32 in thefirst port 35 even if a pull-out force of at least 100 pounds is applied to thefirst connector 32. - The
coupling nut 40 of thefirst connector 32 includes afirst region 180 and asecond region 182. Thefirst region 180 includes a plurality ofgrooves 184 to facilitate grasping of thefirst region 180, such as by a field technician or other user during connection or disconnection of theconnector 32 with theadapter 34. Thegrooves 184 are for example a plurality of longitudinally oriented grooves that enable a user to more easily rotate thecoupling nut 40. Turning of thecoupling nut 40 enables a connection means of thesecond region 182 to engage or disengage with theadapter 34. In the illustrated embodiment, thesecond region 182 includes a connection means ofexterior screw threads 75 adapted to mate withinternal threads 76 provided within thefirst port 35 of theadapter 34. In another embodiment, other connection means may also be used. - The
ferrule assembly 43 of thefirst connector 32 includes a ferrule 100 (e.g., a ceramic ferrule), abarrel 101 mounted on theferrule 100, aspring 102 and aspring holder 104. Theferrule assembly 43 is loaded into thefirst connector 32 while thecover 41 is removed from themain body 36. To load theferrule assembly 43 into theconnector housing 39, theferrule 100 is positioned in thedistal portion 118 a of thecentral passage 118 by inserting theferrule 100 through the proximal end of thedistal portion 118 a. As so inserted, thebarrel 101 abuts against ashoulder 103 located within the plug portion 56 (seeFIGS. 17 and 19 ). Thespring 102 is then inserted into thedistal portion 118 a behind theferrule 100. Thereafter, thespring holder 104 is loaded into a pocket 114 (seeFIGS. 8-11 ) of themain body 36 at a location behind thespring 102 such that thespring 102 is captured within thedistal portion 118 a between thebarrel 101 and thespring holder 104. In this manner, theferrule 100 is spring biased in a distal direction. - The proximal portion of the
connector housing 39 is configured to facilitate providing a secure connection between thefirst cable 20 and thefirst connector 32. For example, theproximal portion 118 b of thecentral passage 118 is sized to receive thebuffer tube 220 of thefirst cable 20. Strength member receivers 120 (e.g., channels, passages, grooves, etc.) are provided on opposite sides of theproximal portion 118 b of thecentral passage 118 for receiving thestrength members 224 of thefirst cable 20. Thebody 36 includesalignment openings 116 that receive corresponding alignment pins 117 of thecover 41 to insure that that cover 41 properly aligns with thebody 36 when mounted thereto. Theconnector housing 39 further includes bleedopenings 122 for allowing adhesive to bleed from the interior of thehousing 39 when thecover 41 is mounted to thebody 36. The interior of thehousing 39 further includes structure for improving adhesion between adhesive and the interior of the housing. For example, the interior of the housing includes a plurality ofslots 123 for improving the adhesion characteristics of the interior surface of thehousing 39. Other adhesion improving structures include knurling, surface roughening, or other structures. - The exterior of the
connector housing 39 includes acircumferential groove 112 for mounting the sealingmember 49. The exterior of thehousing 39 also includescircumferential shoulders 124 and 125 (seeFIG. 7 ), against which thecrimp band 38 can abut after assembly of the connector, and a circumferential shoulder 113 (shown inFIGS. 8 and 9 ). A circumferential recessedportion 128 is defined on the outside of thetabs 58. Retainingteeth 130 are located on the inside of thetabs 58. - Installation of
connector 32 onto the end of afiber optic cable 20 will now be described with reference toFIG. 5 . To begin installation, the end of thefiber optic cable 20 is prepared using a stripping process. In the stripping process, theouter jacket 226 is stripped away to expose thestrength members 224 and thebuffer tube 220. After the stripping process, a portion of thebuffer tube 220 is cut away to expose theoptical fiber 222. - After the end of the
cable 20 has been prepared as described above, theboot 42 is slid onto the end offiber optic cable 20, followed by the sealing tube 106 (e.g., a heat shrink tube or heat shrink tape/wrap), thecoupling nut 40, and thecrimp band 38. The bareoptical fiber 222 is then fed through thespring holder 104 and thespring 102, and is mounted within theferrule 100. Theferrule assembly 43 is then loaded into theplug portion 56 of theconnector housing 39. - Once the ferrule assembly has been loaded into the
connector housing 39, thefirst cable 20 is secured to theconnector housing 39 such thatcable 20 extends longitudinally from theproximal end 54 of thehousing 39.FIGS. 5 and 7 are perspective views of thebody 36 having thecover 41 separated from it, such as in position for installation with a fiber optic cable. To make the connection, thestrength members 224 of thefiber optic cable 20 are inserted intostrength member receivers 120 and thebuffer tube 220 is inserted into theproximal portion 118 b of thecentral passage 118, such that theoptical fiber 222 extends generally along axis A1. Adhesive is then applied to thebuffer tube 220,strength members 224,central passage 118, andstrength member receivers 120, including those in bothbody 36 andcover 41. The adhesive may be an epoxy or any other type of adhesive. Alternatively, fasteners could also be used to connectcover 41 withbody 36. Thebody 36 and thecover 41 are properly aligned by thepins 117 located on the internal side ofcover 41 that are inserted into thealignment openings 116 of thebody 36. Thecover 41 is then squeezed againstbody 36 to enclose thestrength members 224, thebuffer tube 220 and theoptical fiber 222 within theconnector housing 39. Theadhesive bleed openings 122 provided in thebody 36 and thecover 41 enable excess adhesive to be discharged from thehousing 39. When thecover 41 is squeezed onto thebody 36, the excess adhesive flows out frombleed openings 122 and can then be wiped away. - The
fiber optic cable 20 is preferably stripped in the previous steps such that theouter jacket 226 terminates at a shoulder 136 (seeFIGS. 8-11 ) of thehousing 39. Theshoulder 136 is located at the distal ends oftabs 58 and at the proximate ends ofstrength member receivers 120 and thecentral passage 118. Thetabs 58, therefore, cover the end of theouter jacket 226 when thecover 41 and thebody 36 are connected. When thecover 41 and thebody 36 are pressed together, theteeth 130 of thetabs 58 are pressed into or against theouter jacket 226. Theteeth 130 are oriented to resist movement of theouter jacket 226 in the proximal direction away from thebody 36. Therefore, theteeth 130 provide further connection means to hold thefiber optic cable 20 firmly engaged with theconnector housing 39. - After the
cover 41 has been connected with thebody 36 andfiber optic cable 20, thecrimp band 38 is slid over a part of theconnector housing 39 and crimped in place to hold thecover 41 securely onto thebody 36. The sealingtube 106 is then slid over a portion of thecrimp band 38 so as to cover the end of thecable 20, the proximal end of theconnector housing 39 and at least a portion of thecrimp band 38. Heat is then applied to the sealingtube 106 to cause the sealingtube 106 to shrink and tightly form around the adjacent portions of theconnector housing 39, thecrimp band 38, and thefiber optic cable 20, to seal connector from foreign substances. Thecoupling nut 40 is then slid over thecrimp band 38, the sealingtube 106 and theconnector housing 39. Theboot 42 is then slid onto thefirst connector 32 and over the sealingtube 106. Theboot 42 is, for example, a flexible polymeric/rubber material. At the distal end of theboot 42, theboot 42 can include a structure (e.g., an inwardly projecting flange or lip) that provides a mechanical interlock with the recessedportion 128 of thetabs 58. Although thetabs 58 are spaced from theboot 42 by the sealingtube 106, the sealingtube 106 fits tightly around thetabs 58, such that the recessedportion 128 of thetabs 58 can be engaged by theboot 42. The sealingmember 49 is then mounted with thegroove 112 about theconnector housing 39 to complete the installation ofconnector 32 ontofiber optic cable 20. Theboot 42 retains thecoupling nut 40 on theconnector housing 39. - Referring to
FIGS. 1 , 2, 5 and 12, theadapter 34 of the fiberoptic connection system 30 includes anouter housing 44 having afirst housing piece 45 that interconnects with asecond housing piece 47.

FIG. 12 , thefirst region 60 defines thefirst port 35 of theadapter 34.Internal threads 76 are provided within thefirst region 60 adjacent thefirst end 70 of thehousing 44. Theinternal threads 76 within thefirst port 35 are sized to threadingly receive theexterior screw threads 75 of thecoupling nut 40 when the coupling nut is threaded into thefirst port 35 to provide a secure connection between thefirst connector 32 and theadapter 34. - Referring now to
FIGS. 17 and 19 , thefirst housing piece 45 defines anannular sealing surface 78 positioned inside thefirst housing piece 45 at a location adjacent to theinternal threads 76. Anangled diameter transition 79 decreases the internal diameter of thefirst port 35 from theinternal threads 76 to theannular sealing surface 78. Theannular sealing surface 78 is preferably generally cylindrical and is adapted to engage the sealingmember 49 of thefirst connector 32 when thefirst connector 32 is fully inserted within thefirst port 35. The interface between theannular sealing surface 78 and the sealingmember 49 provides an internal environmental seal between thefirst connector 32 and theadapter 34. - Referring still to
FIGS. 17 and 19 , thefirst housing piece 45 defines aninternal pocket 80 within thesecond region 62 for receiving an end portion of thesecond housing piece 47 when thehousing pieces pocket 80 is separated from theannular sealing surface 78 by ashoulder 84 that provides an increase in diameter from theannular sealing surface 78 to thepocket 80. As shown atFIG. 13 , a keying member 150 (e.g., a tab or a rail) is provided at thepocket 80 for ensuring proper rotational alignment between thefirst housing piece 45 and thesecond housing piece 47. The keyingmember 150 is received within a correspondingkeyway 151 defined by thesecond housing piece 47 when the first andsecond housing pieces - The
second housing piece 47 of theadapter 34 includes afirst region 86 separated from asecond region 88 by ashoulder 89. The first andsecond regions shoulder 89 provides a reduction in outer diameter from thefirst region 86 to thesecond region 88. Theretention tabs 174 for interconnecting thefirst housing piece 45 with thesecond housing piece 47 are provided at thesecond region 88. - The
first region 86 of thesecond housing piece 47 includes a pair of oppositely positionedlatches 160 for securing theadapter assembly 140 within thesecond housing piece 47. As shown atFIGS. 12 and 17 , each of thelatches 160 includes aflexible cantilever arm 161 having abase end 162 integrally formed with thesecond housing piece 47, and afree end 163 positioned opposite from thebase end 162.Retention tabs 164 are provided at the free ends 163. Theretention tabs 164 includeangled surfaces 166 that angle toward the central axis of theadapter 34, andretention surfaces 168 that are generally transversely aligned relative to the central axis of theadapter 34. Thefirst region 86 of thesecond housing piece 47 can also include a keying slot 169 (seeFIG. 3 ) for receiving acorresponding rail 165 of thesecond connector 33 to ensure that thesecond connector 33 is inserted into thesecond port 37 at the proper rotational orientation. - The
second region 88 of thesecond housing piece 47 defines thefirst plug receptacle 59 for receiving theplug portion 56 of thefirst connector 32 when the first connector is inserted into thefirst adapter port 35. As previously described, thefirst plug receptacle 59 has a tapered portion defined byopposite surfaces second end 72 of theadapter 34. The tapered configuration of thefirst plug receptacle 59 and theplug portion 56 of thefirst connector 32 facilitates maintaining precise alignment of thefirst connector 32 within theadapter 34. Thefirst region 86 of thesecond housing piece 47 also defines asecond plug receptacle 97 corresponding to thesecond adapter port 37. Thesecond plug receptacle 97 is adapted for receiving thesecond connector 33. - The
adapter assembly 140 of theadapter 34 includes aconnector retention clip 201, asplit sleeve 202, and abacking piece 204. Thesplit sleeve 202 is adapted for receiving the ferrules of the first andsecond connectors adapter 34 to maintain alignment between thefibers 222 of theconnectors connector retention clip 201 includes a pair of latchingarms 206 that interlock with thesecond connector 33 when the second connector is inserted within thesecond port 37 of theadapter 34. In this manner, the latchingarms 206 retainsecond connector 33 within thesecond port 37. Theconnector retention clip 201 also includes acylindrical receptacle 208 for receiving one end of thesplit sleeve 202. The other end of the split sleeve is received within acylindrical receptacle 209 of thebacking piece 204. In this manner, thesplit sleeve 202 is captured between theretention clip 201 and thebacking piece 204.Flanges retention clip 201 and thebacking piece 204 are secured together to retain thesplit sleeve 202 between theretention clip 201 and thebacking piece 204. When thesplit sleeve 202 is mounted between theretention clip 201 and thebacking piece 204, thesplit sleeve 202 has a limited amount of space available for sliding axially within thecylindrical receptacles split sleeve 202 to float within thecylindrical receptacles ferrules 100 of theconnectors - The assembled
adapter assembly 140 is loaded into thesecond housing piece 47 by inserting theadapter assembly 140 into thesecond plug receptacle 97 through thesecond adapter port 37. As theadapter assembly 140 is inserted into thesecond plug receptacle 97, theflanges angled surfaces 166 of thecantilever arms 161 causing the cantilever arms to flex outwardly. After theflanges angled surfaces 166, thecantilever arms 161 snap radially inwardly andretention surfaces 168 of theretention tabs 164 capture and retain theadapter assembly 140 within the second housing piece 47 (seeFIG. 17 ).

Thesplit sleeve 202 is aligned generally along the central axis of theadapter 34. In the depicted embodiment, the adapter does not include structure (e.g., a spring or other biasing or resilient structure) for facilitating allowing theentire adapter assembly 140 to float within theouter housing 44. Instead, theretention tabs 164 prevent theadapter assembly 140 from floating or otherwise moving within theouter housing 44. However, as indicated above, there is a limited amount of space between thesplit sleeve 202, which is disposed within theadapter assembly 140, and thecylindrical receptacles cylindrical receptacles - After the
adapter assembly 140 has been snapped within thesecond housing piece 47 of theouter housing 44, the first andsecond housing pieces second region 88 of thesecond housing piece 47 is inserted into thepocket 80 defined within thesecond region 62 of thefirst housing piece 45. During insertion, rotational alignment is ensured by inserting the keyingmember 150 of thefirst housing piece 45 into thekeyway 151 of thesecond housing piece 47. As thesecond housing piece 47 is inserted into thefirst housing piece 45, thecantilever arms 170 engage theretention tabs 174 causing thecantilever arms 170 to flex radially outwardly. When theopenings 172 of thecantilever arms 170 align with theretention tabs 174, the cantilever arms snap radially inwardly to a locked position in which theretention tabs 174 protrude through theopenings 172. - The
adapter 34 is adapted to be mounted within an opening defined by a wall of theenclosure 19. To mount theadapter 34 in the opening, the mountingnut 46 is first removed. The second end of theouter housing 44 is then inserted from the exterior of the enclosure through the mounting opening until theshoulder 64 abuts against the outside surface of the enclosure wall. Thereafter, the mountingnut 46 is threaded on thethreads 66 until the nut abuts against the inside surface of the enclosure wall. With the enclosure wall captured between theshoulder 64 and the mountingnut 46, theadapter 34 is securely mounted to the enclosure. - As indicated above, the
adapter 34 is configured for providing an optical connection between thefirst connector 32 and thesecond connector 33. To provide this connection, thefirst connector 32 is mounted in thefirst port 35 and thesecond connector 33 is mounted in thesecond adapter port 37. To mount thefirst connector 32 in thefirst adapter port 35, thefirst connector 32 is inserted axially into theport 35 until theplug portion 56 fits within thefirst plug receptacle 59 and thelatch 50 snaps within thenotch 82. As so positioned, theferrule 100 fits within one end of thesplit sleeve 202 and the sealingmember 49 engages theannular sealing surface 78.
