[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 - Figure 5 As shown, an optical fiber communication connector includes a first optical fiber 1 and a second optical fiber 2. The first optical fiber 1 is provided with a first connector 3 on its outside, and the second optical fiber 2 is provided with a second connector 4 on its outside. A set of symmetrical limiting rods 10 are movably connected inside the first connector 3, and a pressure plate 11 is fixedly connected to the outer end of the limiting rod 10. A compression spring 12 is sleeved on the outside of the limiting rod 10. A pressure head 13 is fixedly connected to the outer wall of the pressure plate 11. A threaded sleeve 16 is also sleeved on the outside of the first connector 3.

[0022] like Figure 3 and Figure 4 As shown, a wiring groove 5 is provided on the right side wall of the first terminal block 3. The wiring groove 5 is used to cooperate with the insertion and installation of the socket cylinder 18. A set of symmetrical positioning grooves 6 are also provided on the right side wall of the first terminal block 3. The positioning grooves 6 are used to cooperate with the positioning rod 17 to realize the positioning insertion of the insert 19. A set of symmetrical slots 7 are provided on the bottom surface of the wiring groove 5. The slots 7 are used to cooperate with the insertion of the insert 19. A set of symmetrical grooves 8 are provided on the outer wall of the first terminal block 3. The grooves 8 are used to cooperate with the movement of the limiting rod 10, the pressure plate 11, the compression spring 12 and the pressure head 13. A connecting hole 9 is also provided between the slot 7 and the groove 8. The connecting hole 9 can ensure that the limiting rod 10 enters the slot 7.

[0023] like Figure 3As shown, the limiting rod 10 is inserted into the connecting hole 9, and a pressure plate 11 is fixedly installed on the outer end of the limiting rod 10. The compression spring 12 is sleeved on the outside of the limiting rod 10 and fixedly installed between the pressure plate 11 and the opposite wall of the groove 8. A pressure head 13 is also fixedly installed on the outer wall of the pressure plate 11. When the pressure head 13 is subjected to external pressure, it will cause the pressure plate 11 to move in the groove 8. The pressure plate 11 will force the compression spring 12 to perform a tightening operation, and cause the limiting rod 10 to pass through the connecting hole 9 and be inserted into the limiting hole 20. Therefore, the first terminal block 3 and the second terminal block 4 can be connected and fixed together, and the purpose of preventing loosening and falling off after the first optical fiber 1 and the second optical fiber 2 are connected can be achieved.

[0024] like Figure 3 As shown, a set of symmetrical retaining rings 14 are fixedly installed on the outer wall of the first terminal block 3, and an external thread 15 is also provided on the outer wall of the first terminal block 3 between the symmetrical retaining rings 14. A threaded sleeve 16 is fitted on the outside of the first terminal block 3 and threadedly connected to the external thread 15. After rotating the threaded sleeve 16 between the retaining rings 14, the threaded sleeve 16 moves to one side along the external thread 15 outside the first terminal block 3, which can squeeze the protruding pressure head 13 on the outer wall of the first terminal block 3, so as to apply a squeezing force to the pressure head 13 and to limit the pressure head 13 from rebounding and resetting under the elastic force of the compression spring 12.

[0025] like Figure 5 As shown, a set of symmetrical positioning rods 17 are fixedly installed on the left side wall of the second terminal block 4, and the positioning rods 17 are inserted into the positioning groove 6. After the positioning rods 17 are inserted into the positioning groove 6, the socket 18 can be inserted into the wiring groove 5, and the insert 19 can be positioned and inserted into the slot 7.

[0026] like Figure 5 As shown, a socket 18 is fixedly installed on the left side wall of the second terminal block 4, and the socket 18 is inserted into the wiring groove 5. A set of symmetrical inserts 19 are fixedly installed on the left side wall of the socket 18, and the inserts 19 are inserted into the slot 7. A limiting hole 20 is opened on the top surface of the insert 19, and a limiting rod 10 is inserted into the limiting hole 20. After the socket 18 is inserted into the wiring groove 5, the opposite end faces of the first optical fiber 1 and the second optical fiber 2 can be tightly connected together to realize the wiring operation of the first optical fiber 1 and the second optical fiber 2. When the inserts 19 are inserted into the slot 7 and the limiting rod 10 is inserted into the limiting hole 20, the first terminal block 3 and the second terminal block 4 can be stably and reliably connected together.

[0027] The specific wiring principle and operation of this fiber optic communication connector are as follows:

[0028] Insert the socket 18, mounted on the left side wall of the second connector 4 outside the second optical fiber 2, into the wiring groove 5 opened on the right side wall of the first connector 3 outside the first optical fiber 1. Then, insert the positioning rod 17 on the left side wall of the second connector 4 into the corresponding positioning groove 6 opened on the right side wall of the first connector 3, until the socket 18 is fully inserted into the wiring groove 5. The insert 19, mounted on the left side wall of the socket 18, will then be inserted into the slot 7 opened at the bottom of the wiring groove 5, ensuring that the opposite end faces of the first optical fiber 1 and the second optical fiber 2 are tightly connected. This completes the wiring operation between the first optical fiber 1 and the second optical fiber 2. Then, manually... Rotate the threaded sleeve 16 located between the retaining rings 14 on the outer wall of the first terminal block 3, causing the threaded sleeve 16 to rotate along the external thread 15 on the outer wall of the first terminal block 3 and move to the left. During the rotation and movement, the threaded sleeve 16 will squeeze the symmetrical protruding pressure heads 13 on the outer wall of the first terminal block 3. After being squeezed by the threaded sleeve 16, the pressure heads 13 will gradually enter the groove 8 opened on the outer wall of the first terminal block 3, and the pressure heads 13 will squeeze the pressure plate 11 inward. The pressure plate 11 will force the compression spring 12 fitted outside the limiting rod 10 to tighten, and the limiting rod 10 will pass through the connecting hole 9 and enter Once inside slot 7, the limiting rod 10 will insert into the limiting hole 20 on the top surface of the insert 19 within slot 7. Therefore, by limiting the insert 19 within slot 7, the limiting rod 10 prevents the socket 18 from moving out of the wiring slot 5. This allows the first connector 3 and the second connector 4 to be connected and fixed together, ensuring a secure connection between the first optical fiber 1 and the second optical fiber 2. This effectively prevents the first optical fiber 1 or the second optical fiber 2 from loosening or falling off when subjected to external pulling or stretching, thus improving the stability of the connection and ensuring effective communication. For normal use after connecting the first optical fiber 1 and the second optical fiber 2, if it is necessary to separate the first optical fiber 1 and the second optical fiber 2, simply rotate the threaded sleeve 16 in the opposite direction to move the threaded sleeve 16 to the right. After the threaded sleeve 16 moves to the right, it will no longer compress and restrict the pressure head 13. The compression spring 12 will perform an elastic recovery and extension operation, pushing the pressure plate 11 outward to move the pressure head 13 outward and causing the limiting rod 10 to move out of the limiting hole 20. This will separate the first terminal block 3 and the second terminal block 4, so that the first optical fiber 1 and the second optical fiber 2 are no longer connected. Therefore, the connection and separation operation between the first optical fiber 1 and the second optical fiber 2 is simple and convenient.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
