Description

Attorney Docket No. 0404.0039-PCTOPTICAL FIBER CONNECTOR DEVICE CONFIGURED TO PROVIDE ENHANCED CONNECTOR COUPLING AND IMPROVED OPTICAL FIBER INSTALLATION PERFORMANCECROSS REFERENCE TO RELATED APPLICATIONS

[0002] The present disclosure relates generally to an optical fiber connector, and more particularly to an optical fiber connector configured to provide enhanced connector coupling and improved optical fiber installation performance.BACKGROUND

[0003] Optical fibers (e.g., single mode fiber) are often pre-terminated at both ends with a connector, such as an LC connector, that is configured to be connected with an outer housing after the pre-terminated end is deployed to its desired location. The preterminated end and the housing are then ready to plug into a matching receptacle. For example, to connect an optical fiber terminated with a first LC connector to another optical fiber terminated with a second LC connector, an adapter is required that can operatively connect the two LC connectors together; thus adding cost, complexity, and assembly time.

[0004] There is a need for a quick connection used to operatively couple terminated optical fibers that is cost-effective, simple, and quick. Accordingly, it may be desirable to provide an optical fiber connector that provides a quick connection between terminated optical fibers without necessarily the need for additional hardware, such as an adapter. Thus, it may be desirable to provide an optical fiber connector that may provide an enhanced connector coupling to another optical fiber connector. It also may be desirableAttorney Docket No. 0404.0039-PCT to provide a connector configured to terminate two optical fibers and connect the two optical fibers with another two optical fibers terminated with a same connector.SUMMARY

[0087] In some embodiments, the locking portion 160 may include a coupling retaining portion 192 structurally configured to resist the optical fiber connector 10 from decoupling from the second optical fiber connector 16. The coupling retaining portion 192 may be configured in a variety of ways. In some embodiments, the coupling retaining portion 192 may include a projecting portion 194 and a recessed portion 196 structurally configured to engage with corresponding structure of the second optical fiber connector 16. In some embodiments, the projecting portion 194 may be positioned on the distal coupling housing portion 124 and the recessed portion 196 may be positioned on the inner side wall surface portion 174 of the actuating portion 162.

[0088] In some embodiments, the locking portion 160 may include a biasing portion 200 (FIG. 2) structurally configured to bias the actuating portion 162 to the locked position. The biasing portion 200 may be configured in a variety of ways. In some embodiments, the biasing portion 200 may include a coil spring structurally configured to be positioned between the actuating portion 162 and the distal housing portion 104 to bias the actuating portion 162 distally relative to the distal housing portion 104.

[0089] As shown in FIGS. 7-8, the optical fiber connector 10 may connect directly to the second optical fiber connector 16, which may be structurally configured the same as, or similar to, the optical fiber connector 10. Thus, the description of the optical fiber connector 10 may apply equally to the second optical fiber connector 16. For example, the second optical fiber connector 16 may include a second proximal optical fiber coupling portion 228 structurally configured to terminate a third optical fiber 230 of the second optical fiber cable 14 and a second distal optical fiber coupling portion 232 structurally configured to terminate a fourth optical fiber 234 of the second optical fiber cable 14.

[0090] To connect the optical fiber connector 10 to the second optical fiber connector 16, the second optical fiber connector 16 may be arranged for the proximal optical fiber coupling portion 28 to couple with the second distal optical fiber coupling portion 232 andAttorney Docket No. 0404.0039-PCT the distal optical fiber coupling portion 32 to couple with the second proximal optical fiber coupling portion 228. In particular, the proximal ferrule portion 36 of the proximal optical fiber coupling portion 28 is received within a sleeve portion 252 of the second distal optical fiber coupling portion 232 to operatively couple to a distal ferrule portion 246 of the second distal optical fiber coupling portion 232.

[0091] The first and second optical fiber connectors 10, 16 may be held together by the locking portion 160 and a corresponding second locking portion 260 of the second optical fiber connector 16 when in the locked position. For example, in the locked position, the projecting portion 194 on the distal coupling housing portion 124 may be received in a recessed portion (not shown), similar to the recessed portion 196, on a second actuating portion 262 of the second locking portion 260. Likewise, a second projecting portion (not shown), similar to the projecting portion 194, on the second distal coupling housing portion 224 may be received in the recessed portion 196 on actuating portion 162.

[0092] To disconnect the optical fiber connector 10 to the second optical fiber connector 16, the second optical fiber connector 16, the actuating portions 162, 262 may be moved to the unlocked position. The actuating portions 162, 262 may be moved to the unlocked position by applying sufficient force to the actuating portions 162, 262 to overcome the engagement between the projecting portions and the recessed portions and the biasing portion. Once the actuating portions 162, 262 are moved to the unlocked position, the optical fiber connector 10 and the second optical fiber connector 16 may be pulled apart.

[0093] Referring to FIGS. 9-10, the optical fiber connector 10 may include a cover portion 280 (e.g., an end cap or cover) structurally configured to cover and protect the coupling portion 26 (FIG. 1 ) when not coupled to, for example, the second optical fiber connector 16. The cover portion 280 may be configured in a variety of ways. In some embodiments, the cover portion 280 may include a proximal portion 282, a distal portion 284 opposite the proximal portion 282, and a sidewall portion 286 extending between the proximal portion 282 and the distal portion 284. In some embodiments, the cover portionAttorney Docket No. 0404.0039-PCT280 may include a first receiving portion 288 structurally configured to receive and / or engage the distal optical fiber coupling portion 32 and a second receiving portion 290 structurally configured to receive and / or engage the proximal optical fiber coupling portion 28.

[0094] In some embodiments, the first receiving portion 288 may include a recessed portion 292 at least partially defined by the sidewall portion 286. In some embodiments, the second receiving portion 290 may include a projecting portion 294 extending from the distal portion 284 of the cover portion 280. The second receiving portion 290 may include a second recessed portion 296 at a distal end portion 298 of the projecting portion 294. The second recessed portion 296 may be structurally configured to receive the proximal ferrule portion 36 of the proximal optical fiber coupling portion 28.

[0095] In some embodiment, the projecting portion 294 may include a guide portion 300 structurally configured to guide the cover portion 280 into engagement with the coupling portion 26. The guide portion 300 may be configured in a variety of ways. In some embodiments, the guide portion 300 may include a groove portion 302 extending axially and being structurally configured to receive the lateral projecting portion 156 of the distal coupling housing portion 124. In some embodiments, the groove portion 302 may be positioned on a lateral side portion 304 of the projecting portion 294.

[0096] In use, the cover portion 280 may be moved (e.g., slid axially) onto the coupling portion 26 such that the distal optical fiber coupling portion 32 is received in the first receiving portion 288 and the proximal ferrule portion 36 is received in the second receiving portion 290 on the projecting portion 294 and the lateral projecting portion 156 is received in the groove portion 302 of the projecting portion 294.

[0097] FIGS. 11-12 illustrate an example fiber routing portion 320. The fiber routing portion 320 may be substantially similar to the fiber routing portion 120 of FIG. 4. Thus, the description of the fiber routing portion 120 applies equally to the fiber routing portion 320. For example, the fiber routing portion 320 may be structurally configured to route optical fiber from the fiber receiving portion 114 to the coupling portion 26 (FIG. 1 ). In some embodiments, the fiber routing portion 320 may be structurally configured to route the first optical fiber 30 from the first optical fiber cable 12 to the proximal optical fiber coupling portion 28 and a second optical fiber 34 from the first optical fiber cable 12 toAttorney Docket No. 0404.0039-PCT the distal optical fiber coupling portion 32. In some embodiments, the fiber routing portion 320 may define an optical fiber passage portion 322 structurally configured for one or more optical fibers to be routed therethrough. In some embodiments, the optical fiber passage portion 322 may be bifurcated. In some embodiments, the optical fiber routing portion 320 may include a first routing portion 324 (e.g., lower half-shell) and a second routing portion 326 (e.g., upper half-shell) configured to overlay the first routing portion 324 to form the optical fiber passage portion 322.

[0098] In some embodiments, the optical fiber routing portion 320 may include a guide portion 328 structurally configured to guide assembling the first routing portion 324 to the second routing portion 326 together. In some embodiments, the guide portion 328 may include a projecting portion 330 (e.g., protrusion, ridge, tongue, bump, pin, etc.) configured to be received in a recessed portion 332 (e.g., cavity, hole, channel, groove, etc.). In some embodiments, the second routing portion 326 may include the projecting portion 330 and the first routing portion 324 may include the recessed portion 332. In some embodiments the projecting portion 330 and the recessed portion 332 may be positioned at or adjacent opposing lateral side portions 334 of the fiber routing portion 320.

[0099] In some embodiments, the fiber routing portion 320 may include a coupling portion 340 structurally configured to couple the first routing portion 324 and the second routing portion 326 together. The coupling portion 340 may be configured in a variety of ways. For example, the coupling portion 340 may include a snap connection, a clipping connection, a latch and a keeper arrangement, a friction fit, or other mechanical fastening configurations. In some embodiments, the coupling portion 340 may include a projecting portion 342 structurally configured to be received in a receiving portion 344. For example, in some embodiments, the first routing portion 324 may include the projecting portion 342 and the second routing portion 326 may include the receiving portion 344.

[0100] In some embodiments, the projecting portion 342 may include a proximal portion 346 and a distal portion 348 opposite the proximal portion 346. In some embodiments, the proximal portion 346 may be fixed relative to the rest of the first routing portion 324 and the distal portion 348 may be unsupported (e.g., a cantilever configuration). In some embodiments, the distal portion 348 may be bifurcated having aAttorney Docket No. 0404.0039-PCT first projecting portion 350 and a second projecting portion 352. Each of the first projecting portion 350 and the second projecting portion 352 may be structurally configured to flex inward during attaching the first routing portion 324 and the second routing portion 326 together. In some embodiments, each of the first projecting portion 350 and the second projecting portion 352 may include a proximally-facing engagement surface portion 354 (e.g., radial shoulder) configured to face toward the proximal portion 346 of the projecting portion 342. In some embodiments, the distal portion 348 may include a wider or enlarged portion 355 (e.g., a head portion)

[0101] In some embodiments, the receiving portion 344 may include a passage portion 356 and a distally-facing engagement surface portion 358 (e.g., a radial shoulder) structurally configured to face opposite the proximally-facing engagement surface portion 354. In some embodiments, the passage portion 356 may extend through the second routing portion 326. In some embodiments, the passage portion 356 may include a narrower passage portion 359 (e.g., smaller diameter) and a wider passage portion 361 (e.g., a larger diameter).

[0102] To couple the first routing portion 324 and the second routing portion 326 together, the second routing portion 326 may be aligned on top of the first routing portion 324 such that the projecting portion 342 is received through the passage portion 356. As the wider or enlarged portion 355 of the projecting portion 342 passes through the narrower passage portion 359, the first projecting portion 350 and a second projecting portion 352 flex inward. Once the wider or enlarged portion 355 moves past the narrower passage portion 359, the first projecting portion 350 and a second projecting portion 352 return outward such that the proximally-facing engagement surface portion 354 is opposed the distally-facing engagement surface portion 360 to prevent separation of the first routing portion 324 and the second routing portion 326.
