The assembly block 3 is provided with an assembly groove 31, and the assembly block 3 is also provided with a hole communicating with the assembly groove 31 for the optical fibers to pass through. When the upper cover plate 1 and the lower cover plate 2 are closed, they can be inserted into the assembly groove 31. The side wall of the assembly block 3 is provided with a locking groove 32 communicating with the assembly groove 31. The upper cover plate 1 and the lower cover plate 2 are fixedly provided with a locking block 21 that can be inserted into the locking groove 32. Assembly block 3 is provided with a locking groove 33 perpendicular to the retaining groove 32. A locking block 4 is slidably mounted within the locking groove 33. Locking block 4 can be inserted into the retaining groove 32 and abut against retaining block 21. A locking spring 41, connected to locking block 4, is fixedly mounted on the inner wall of the locking groove 33. The surface of assembly block 3 is provided with a first anti-slip groove 35. With the cooperation of the locking spring 41, the locking rod abuts against retaining block 21 inserted into the retaining groove 32, thereby completing the assembly of the connector and the optical fiber. This eliminates the need for twisting and tightening, simplifying the operation, saving time, and improving assembly convenience.

[0035] To improve the stability of the assembly, refer to Figures 2 to 4The upper cover plate 1 and the lower cover plate 2 are each provided with a first positioning groove 22. A positioning block 221 is slidably mounted in the first positioning groove 22. A positioning spring 222 connected to the positioning block 221 is provided on the bottom wall of the first positioning groove 22. The assembly block 3 is provided with a second positioning groove 34 connected to the assembly groove 31. The positioning blocks 221 on both the upper cover plate 1 and the lower cover plate 2 can be inserted into the second positioning groove 34. The length of the second positioning groove 34 is greater than the sum of the widths of the two sets of retaining blocks 21, and the distance between the opposing sides of the two retaining blocks 21 is less than the distance between the opposing sides of the two positioning blocks 221. The sidewalls of the positioning blocks 221 are provided with a first inclined surface 223, and the assembly block 3 is provided with a second inclined surface 36 that can abut against the first inclined surface 223. By inserting the positioning block 221 into the second assembly groove 31 and abutting against the inner wall of the second assembly groove 31, the stability of the upper cover plate 1 and the lower cover plate 2 inserted into the assembly groove 31 is improved, thereby improving the stability of the overall assembly.

[0036] To further improve the stability of the assembly, refer to Figures 3 to 5 The second positioning groove 34 communicates with both the locking groove 33 and the latching groove 32. The width of the second positioning groove 34 is greater than that of the latching groove 32. The locking block 4 is provided with a connecting groove 42 extending through the locking groove 33. A connecting block 421 is slidably mounted within the connecting groove 42. An auxiliary groove 422 is provided on the inner wall of the connecting groove 42. An auxiliary block 423 is integrally fixedly mounted on the side wall of the connecting block 421 and slidably mounted within the auxiliary groove 422. The positioning block 221 can be inserted into the connecting groove 42 and abut against the connecting block 421. The connecting block 421 can be inserted into the second positioning groove 34.

The surface of the connecting block 421 is provided with a second anti-slip pattern 44. When the positioning block 221 is inserted into the second positioning groove 34 , the positioning block 221 is inserted into the clamping groove 42 and pushes the clamping block 421 to be adapted and inserted into the second positioning groove 34 , thereby further limiting the position and improving the stability of the assembly.

[0037] The implementation principle of an optical communication connector in an embodiment of the present application is as follows: the assembly block 3 is put on the optical fiber, and the optical fiber is inserted into the hole between the upper cover plate 1 and the lower cover plate 2, the upper cover plate 1 and the lower cover plate 2 are closed, the locking rod is pushed to insert into the locking groove 33 and compress the locking spring 41, and the upper cover plate 1 and the lower cover plate 2 are inserted into the assembly groove 31 of the assembly block 3. During this process, the locking block 21 is inserted into the locking groove 32, and under the guidance of the first inclined surface 223 and the second inclined surface 36, the positioning block 221 retreats into the first positioning groove 22 and compresses the positioning spring 222. When the locking block 21 is against the inner wall of the locking groove 32, the positioning spring 222 recovers and pushes the positioning block 221 to insert into the second positioning groove 34. At this time, the locking block 4 is released, the quality spring recovers, and pushes the locking rod to slide and insert into the locking groove 32. In this process, under the guidance of the third inclined surface 224 and the fourth inclined surface 43, the locking block 4 pushes the positioning block 221 to retract into the first positioning groove 22 and compress the positioning spring 222. When the locking block 4 is against the inner walls on both sides of the locking groove 33, the positioning block 221 is aligned with the clamping block 421. At this time, the positioning spring 222 recovers and pushes the positioning block 221 to insert into the clamping groove 42. The positioning block 221 pushes the clamping block 421 to slide and fit into the second positioning groove 34 to complete the assembly. During disassembly, the clamping block 421 is pushed out of the second positioning groove 34. The clamping block 421 then pushes the positioning block 221 out of the clamping groove 42 and retracts into the first positioning groove 22. At this point, the upper cover 1 and the lower cover 2 are pulled out to complete the disassembly. Compared to the tail sleeve in the prior art that requires threaded tightening, the present application does not require tightening, thus reducing assembly time and eliminating the need for forceful operation, thereby improving assembly convenience.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
