[0002] Fiber optic connectors are devices that allow for detachable connections between optical fibers. They precisely align the two end faces of the optical fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber and minimize the impact on the system caused by their intervention in the optical link. These are the basic requirements of fiber optic connectors.

[0003] Meanwhile, a fiber optic connector device with announcement number CN106990483A is disclosed. Its structure includes a latch, a sleeve, a slot block, a contact terminal, a protective opening, a latch hole, a connector, a limiting block, a tail sleeve, a connector, and a base. The tail end of the base is clearance-fitted with the latch, and the tail sleeve is threadedly connected to the base through the latch. The sleeve, slot block, latch hole, and connector are an integral structure and clearance-fitted with the base. The contact terminal is installed inside the protective opening, which is located at the top of the base. The limiting block is connected to the right side of the latch, and the connector is installed inside the base.

[0004] The aforementioned fiber optic connector device does not securely fix the fiber optic cable during use, causing the fiber optic cable to detach and become damaged, thus increasing operating costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following describes an embodiment of this utility model based on its overall structure.

[0027] like Figures 1 to 5 As shown, this utility model provides a locking-type high-security optical fiber connector device for a communication optical cable junction box, including a connector 1. A connecting tube 6 is fixedly installed on the left side of the connector 1, and a housing 10 is fixedly installed on the left side of the connecting tube 6. A turntable 5 is rotatably installed on the left side of the housing 10. A rotating shaft 7 is fixedly installed on the right side of the turntable 5. A gear 8 is fixedly installed on the outside of the rotating shaft 7. A gear 13 is attached to the outside of the gear 8. A rotating shaft 14 is rotatably installed inside the gear 13. A lead screw 9 is spirally installed inside the rotating shaft 14. Rotating the turntable 5 causes the gear 8 to rotate with the rotating shaft 7, thereby causing the gear 13 outside the gear 8 to rotate. This causes the lead screw 9 inside the gear 13 to move up and down, shortening the distance between the rubber fixing posts 12 at the end of the lead screw 9, thereby fixing the optical fiber 2.

[0028] In this embodiment, a rubber fixing post 12 is fixedly provided at the end of the lead screw 9, and a fixing rod 11 is fixedly provided on the right side of the rotating shaft 14. The fixing rod 11 is fixedly set to the outer shell 10. The rubber fixing post 12 will not damage the optical fiber 2 during the clamping process. The fixing rod 11 is used to fix the gear 13. A connector head 15 is fixedly provided on the right side of the connector 1. A fixing groove 24 is opened inside the upper part of the connector 1. A buckle 23 is fitted inside the fixing groove 24. A connecting post 21 is fixedly provided above the buckle 23. A spring 22 is fitted outside the connecting post 21. A fixing post 20 is fixedly provided above the connecting post 21. The spring 22 plays a buffering role. A connector 29 is fitted on the right side of the connector 1. A connecting hole 26 is opened inside the connector 29. A fixing plate 16 is fixedly installed on the left side of the turntable 5. A square hole 18 is opened inside the fixing plate 16. A junction box 27 is fixedly installed on the outside of the connector 19. The fixing plate 16 is inserted into the fixing groove 24. The buckle 23 is pushed upward by the spring 22. When it encounters the square hole 18, it falls into the fixing groove 24, fixing the fixing plate 16 and connecting the connector 11 and the connector 19. A fixing groove 25 is opened on the lower right side of the connector 1. A fixing plate 17 is fitted inside the fixing groove 25 and fixedly installed with the connector 19. A connecting post 4 is fixedly installed on the left side of the turntable 5. A hollow post 3 is fixedly installed on the left side of the connecting post 4. An optical fiber 2 is fitted inside the hollow post 3. The fixing plate 17 is inserted into the fixing groove 25 to limit and fix the connection between the connector 11 and the connector 19.

[0029] Working principle and process of the interlocking high-security optical fiber junction box fiber optic connector device:

[0030] In use, the interlocking high-security optical fiber junction box fiber optic movable connector device involves passing the optical fiber 2 through the hollow column 3, then through the connecting column 4 into the outer casing 10, and finally through the connecting tube 6 into the connector 1. Next, rotating the turntable 5 causes gear 8 to rotate with shaft 7, which in turn causes gear 13 outside gear 8 to rotate with shaft 14. This causes the lead screw 9 inside gear 13 to move up and down, shortening the distance between the rubber fixing posts 12 at the end of the lead screw 9, thereby securing the optical fiber 2. After installation, install connector 19 into junction box 27, insert fixing plate 16 into fixing slot 24, and push buckle 23 upward by spring 22. When it encounters square hole 18, it falls into fixing slot 24, fixing plate 16. Connect connector 1 and connector 19, so that connector head 15 contacts connecting hole 26. To disassemble, pull fixing post 20 directly. Under the action of spring 22, buckle 23 leaves fixing slot 24, and connector 19 can be taken out.
