The locking mechanism is arranged on the limiting mechanism, and the locking mechanism is used to fix the limiting mechanism. The auxiliary mechanism is arranged on the female connector 3, and the auxiliary mechanism is used to assist the disassembly of the male connector 1 and the female connector 3. The connecting ring 2 is provided with a sliding groove for sliding two limiting arc plates 6.

[0057] It should be noted that the maximum diameter of the fixing ring 4 is equal to the maximum diameter of the female connector 3, and the connecting ring 2 and the fixing ring 4 are slidably and sealedly matched, and the connecting ring 2 and the inner wall of the female connector 3, i.e., the opening 1, are also slidably and sealedly matched.

[0058] Specifically, the limiting mechanism includes: a fixed shell 5, a limiting arc plate 6 and a driving assembly. The fixed shell 5 is fixedly mounted on the fixed ring 4 and the female connector 3. Two limiting arc plates 6 are sealed and slidably installed between the fixed ring 4 and the female connector 3. The driving assembly is mounted on the fixed shell 5, and the driving assembly is used to drive the two limiting arc plates 6 to move closer to or away from each other.

[0059] Correspondingly, the driving assembly includes: a gear 7, a rack 8 and a control rod 9. The gear 7 is rotatably installed in the fixed shell 5. Two racks 8 are slidably installed in the fixed shell 5. The two racks 8 are meshed with the gear 7. The two racks 8 are respectively fixedly connected to the two limiting arc plates 6. The control rod 9 is fixedly installed on the gear 7. The control rod 9 extends to the outside through the fixed shell 5. A torsion spring 10 is fixedly installed on the fixed shell 5. A fixed plate 11 is fixedly sleeved on the control rod 9. One end of the torsion spring 10 is fixedly connected to the fixed plate 11.

[0060] Specifically, the locking mechanism includes: a slide rod 12, a block 13 and a fixed component. A support frame is fixedly installed on the fixed shell 5, and the slide rod 12 is slidably installed on the support frame. A docking hole is opened on the control rod 9, and multiple blocks 13 are fixedly installed on the inner wall of the docking hole. A plurality of slots for the sliding of the block 13 are opened at the bottom of the slide rod 12, and the fixed component is arranged on the support frame.

[0061] Correspondingly, the fixing assembly includes: a fixing block 14, a pulley 15, a supporting bent rod 16, a pulley 2 17 and a spring 18. The fixing block 14 is fixedly sleeved on the upper side of the sliding rod 12. Two pulleys 15 are rotatably installed on the fixing block 14. Two openings 2 are provided on the supporting frame. Supporting bent rods 16 are slidably installed in the two openings 2. A pulley 2 17 is rotatably installed on each supporting bent rod 16. The two pulleys 2 17 are respectively in contact with the two pulleys 15. Springs 18 are fixedly installed in the two openings 2. The other ends of the two springs 18 are respectively fixedly connected to the two supporting bent rods 16. Among them, a plurality of openings 3 are provided on the supporting frame. A clamping plate 19 is slidably installed in the plurality of openings 3. The plurality of clamping plates 19 are fixedly connected to the sliding rod 12.

[0062] It should be noted that before the male connector 1 and the female connector 3 are connected, the two pulleys 15 are located on the upper side of the two pulleys 2 17. After the male connector 1 and the female connector 3 are connected, the two pulleys 15 are located on the lower side of the two pulleys 2 17, and the two pulleys 2 17 are used to support the two pulleys 2 17 to prevent the card slot from moving away from the card block 13, thereby causing the male connector 1 and the female connector 3 to loosen.

[0063] Specifically, the auxiliary mechanism includes: a sealing ring 20, an elastic rod 21 and a propulsion assembly. An opening four is opened on the female connector 3, and the sealing ring 20 is slidably installed in the opening four. A plurality of elastic rods 21 are fixedly installed on the sealing ring 20. The output ends of the plurality of elastic rods 21 all pass through the opening four and extend into the opening one. The plurality of elastic rods 21 are in contact and cooperate with the connecting ring 2. Two propulsion assemblies are provided on the female connector 3.

[0064] Correspondingly, the propulsion assembly includes: an installation shell 22, a threaded rod 23 and a connecting bent rod 24. The installation shell 22 is fixedly installed on the female connector 3, the threaded rod 23 is rotatably installed in the installation shell 22, one end of the connecting bent rod 24 is threadedly connected to the threaded rod 23, and the other end of the connecting bent rod 24 is fixedly connected to the sealing ring 20.

[0065] It should be noted that the output ends of the multiple elastic rods 21 pass through the opening four and extend into the opening one. When the output ends of the multiple elastic rods 21 push the connecting ring 2, the output ends of the multiple elastic rods 21 slide at the penetration between the opening four and the opening one.

[0066] In this embodiment, the working principle of the prefabricated circular introduction cable connector of the optical fiber cable is as follows: when the male connector 1 and the female connector 3 are docked, the male connector 1 is inserted into the female connector 3, and the connecting ring 2 slides into the opening 1. When the connecting ring 2 slides to a certain position, that is, the gap between the slide groove and the fixed ring 4 and the female connector 3 is aligned, and then the control rod 9 is rotated. When the control rod 9 is rotated, the gear 7 will rotate accordingly. As the gear 7 rotates, the two racks 8 mesh with the gear 7, so that the two racks 8 slide on the fixed housing 5 and drive the two limit arc plates 6 to close to each other. The control rod 9 is rotated to generate torque on the torsion spring 10 until the two limit arc plates 6 slide into the slide groove and the outer walls of the two limit arc plates 6 are aligned with the outer walls of the female connector 3. Then the slide bar 12 is pressed downward to insert the slide bar 12 into the docking hole. At this time, the card slot will wrap the card block 13 so that the card block 13 is located in the card slot. At this time, multiple card plates 19 will slide into multiple openings three respectively, and while pressing the slide bar 12 downward, the two pulleys 15 will contact the two pulleys 2 17 respectively. The two pulleys 15 will move downward. At this time, the two pulleys 2 17 will be squeezed by the two pulleys 15 respectively. Then, the two supporting bent rods 16 are moved away from each other. At this time, the two springs 18 are squeezed by the two supporting bent rods 16 respectively, until the two pulleys 15 move below the two pulleys 2 17, and then the pressing of the slide bar 12 is stopped. The two springs 18 will push the two supporting bent rods 16 to reset, so that the two pulleys 2 17 press the two pulleys 1 15, and then the two threaded rods 23 are rotated. With the rotation of the two threaded rods 23, the two connecting bent rods 24 drive the sealing ring and the multiple elastic rods 21 to move in the direction of the opening 1, until the output ends of the multiple elastic rods 21 push against the connecting ring 2, and the multiple elastic rods 21 have moving pressure. The threaded rod 23 can be stopped from rotating. When the male connector 1 and the female connector 3 are disassembled, the slide is pulled upward to move the two pulleys 15 to the top of the two pulleys 2 17 and move the slot away from the block 13. After the slot is away from the block 13, the torsion spring 10 releases the torque to drive the control rod 9 to flip. As the control rod 9 flips, the gear 7 is driven to flip. As the gear 7 reverses, the two racks 8 respectively drive the two limit arc plates 6 away from each other. Until the limit arc plates 6 are away from the slide slot, the multiple elastic rods 21 will push the connecting ring 2 to slide in the opening 1, so that the connecting ring 2 slides out of the opening 1, and the disassembly is completed.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
