Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, specifically to an optical fiber fixing structure for an optical fiber adapter. Background Technology

[0002] A fiber optic connector is a device that allows for a detachable (movable) connection between optical fibers. It precisely aligns the two end faces of the optical fibers to maximize the coupling of the light energy output from the transmitting fiber to the receiving fiber and minimize the impact on the system caused by its intervention in the optical link.

[0003] When installing a connector (equivalent to socket 1 in this application) at the end of an optical fiber, the optical fiber needs to be fixed inside the connector, which is then tightened with pliers. However, this method of fixing the optical fiber is prone to loosening, causing the optical fiber to move within the connector and resulting in poor signal transmission. To address this, we propose an optical fiber fixing structure for an optical fiber adapter. Utility Model Content

[0004] This invention provides a fiber optic fixing structure for a fiber optic adapter, which has the advantage of fixing the conduit inside the socket and preventing the fiber optic cable from being pulled out, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A fiber optic fixing structure for a fiber optic adapter includes a socket, one end of which is provided with a fiber core hole, and the other end of which is provided with a fiber optic hole communicating with the fiber core hole. The fiber optic hole and the fiber core hole are directly stepped. A clamping port is provided on the surface of the socket. The clamping port is located at the fiber optic hole and the two are interconnected. A clamping seat is placed inside the clamping port.

[0009] Preferably, the top of the socket is provided with a strip block, and the top two ends of the adapter housing are respectively provided with sockets that match the strip block. Two elastic seats are symmetrically installed in the middle of the top surface of the adapter housing. The elastic seats are parallel to the sockets above.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figures 1 to 4 This utility model provides a technical solution: an optical fiber fixing structure for an optical fiber adapter, including a socket 1, one end of the socket 1 is provided with a fiber core hole 9, the size of the fiber core hole 9 is matched with the size of the fiber core in the optical fiber, the other end of the socket 1 is provided with an optical fiber hole 18 communicating with the fiber core hole 9, the optical fiber hole 18 and the fiber core hole 9 are directly stepped, that is, the diameter of the optical fiber hole 18 is larger than the diameter of the fiber core hole 9, because the optical fiber hole 18 is used to place the optical fiber (including the optical fiber sheath).

[0021] like Figure 1 As shown, one end of the socket 1 near the fiber optic core hole 9 has a coaxial cylindrical hole 8. A cylindrical head 10 is coaxially installed inside the cylindrical hole 8, with the end of the cylindrical head 10 extending outside the cylindrical hole 8. The fiber optic core hole 9 is coaxially located inside the cylindrical head 10. This design is mainly for use with fiber optic adapters. The fiber optic adapter is matched with the socket 1, such as... Figure 1 and Figure 2 As shown, socket 1 is inserted into both ends of the fiber optic adapter;

[0022] The fiber optic adapter's specific structure includes an adapter housing 15 with openings at both ends, such as... Figure 3 As shown, a sealing seat 19 is provided in the middle of the adapter housing 15. On both sides of the sealing seat 19, there are cylindrical seats 14 coaxial with the adapter housing 15. Both the cylindrical seats 14 and the sealing seat 19 are provided with mating holes 20. It should be noted that the diameter of the cylindrical seat 14 is smaller than the inner diameter of the adapter housing 15, so that there is a cavity between the cylindrical seat 14 and the adapter housing 15, which matches the socket 1.

[0023] During installation, sockets 1 are inserted into both ends of the adapter housing 15, such as... Figure 3 and Figure 4 As shown, the cylindrical base 14 is placed in the cylindrical hole 8, and the cylindrical head 10 is placed inside the cylindrical base 14. After the socket 1 is completely placed inside the adapter housing 15, the two cylindrical heads 10 are connected in the mating hole 20.

[0024] It should be noted that when installing the optical fiber, first strip the outer sheath from one end of the fiber to expose the fiber core. Then, insert the fiber into the socket 1 through the fiber hole 18, placing the fiber core in the fiber core hole 9. Finally, smooth the end of the fiber core hole 9 to the end of the cylindrical head 10. Figure 4As shown, when the two cylindrical heads 10 are mated, the two fiber cores are also mated simultaneously. Furthermore, this application focuses on the fact that the surface of the socket 1 is provided with a clamping port 17, which is located at the fiber optic hole 18 and the two are interconnected. It should be emphasized here that, as... Figure 3 As shown, the depth of the clamping port 17 cannot exceed half the diameter of the fiber optic hole 18, because the clamping port 17 contains a clamping seat 4, and the clamping seat 4 is detachably connected to the socket 1. This is to prevent the clamping seat 4 from forming a shearing force on the fiber optic cable when clamping it, thus preventing the fiber optic cable from being cut. The clamping seat 4 has a clamping groove 5 that matches the fiber optic cable below it. When clamping the fiber optic cable, the clamping groove 5 cooperates with the fiber optic hole 18.

[0025] The two ends of the clamping seat 4 are fastened to the socket 1 by screws or bolts, or the clamping seat 4 is snapped into the clamping port 17, or the two ends of the clamping seat 4 are connected to the socket 1 by latches or buckles. When the clamping seat 4 is placed in the clamping port 17, the clamping seat 4 clamps the optical fiber located in the optical fiber hole 18. At this time, the fiber core inside the optical fiber is placed in the fiber core hole 9. In this way, the clamping seat 4 can firmly fix the optical fiber in the socket 1, and prevent the optical fiber from slipping unnecessarily during insertion and removal.

[0026] Furthermore, to make socket 1 more stable, such as Figure 1 As shown, the socket 1 has slots 2 on both sides, and plugs 16 corresponding to the slots 2 are provided on the inner walls of both ends of the adapter housing 15. The plugs 16 are placed in the slots 2. The cooperation between the plugs 16 and the slots 2 can make the socket 1 more stable, and can also make the socket 1 stably placed in the adapter housing 15.

[0027] like Figure 1 As shown, a strip block 7 is provided on the top of the socket 1, and sockets 13 matching the strip block 7 are provided at both ends of the top of the adapter housing 15. Two elastic seats 11 are symmetrically installed in the middle of the top surface of the adapter housing 15. The elastic seats 11 are made of plastic or metal and are positioned parallel above the sockets 13. A locking block 12 is provided at the bottom of the end of each elastic seat 11. The locking block 12 extends into the socket 13. When the socket 1 is placed inside the end of the adapter housing 15, the strip block 7 is placed in the socket 13. A slot 6 corresponding to the locking block 12 is provided on the top of the strip block 7. As the strip block 7 is pushed into the socket 13, the strip block 7 lifts the elastic seat 11. Under the action of the elastic seat 11, the locking block 12 is locked in the slot 6. This allows the socket 1 to be stably positioned inside the end of the adapter housing 15 and not to slide outward.

[0028] Based on the above embodiments, further optimization can be achieved by providing a protective sleeve 3 at the end of the socket 1 away from the fiber core hole 9, which communicates with the fiber optic hole 18. The protective sleeve 3 is elastic and can be placed on the optical fiber to prevent the optical fiber from breaking.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
