Description

Technical Field

[0001] The present application relates to the technical field of optical fiber couplers, and in particular to an optical fiber locking device for optical fiber coupling. Background Art

[0002] Fiber optic couplers are used to split or combine optical signals, that is, to distribute an input optical signal to multiple outputs or to combine multiple input optical signals into one output. Existing fiber optic coupling connectors usually include a plug mechanism and a socket mechanism. The plug mechanism and the socket mechanism are in a male-female docking relationship. The optical fiber is connected to the plug mechanism and then inserted into the socket mechanism to complete the fiber optic coupling.

[0003] At present, the plug and the socket, the optical fiber and the plug are connected by plug-in fastening. Although it is convenient for coupling, connecting and disassembling the optical fiber, the shaking of the optical fiber during use will cause the connection with the plug to be unstable, resulting in transmission being affected. Moreover, when the optical fiber drives the plug to shake, the connection between the plug and the socket will become unstable, causing wear or limited signal transmission. Therefore, an optical fiber locking device is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a fiber locking device for fiber coupling. Figure 1-3, an optical fiber locking device for optical fiber coupling, comprising a socket 1, a plug 2 is plugged into the upper and lower ends of the socket 1, an optical fiber line 3 is plugged into the end of the plug 2 away from the socket 1, wherein both sides of the plug 2 are fixedly connected to a fixed block 4, the fixed block 4 is slidably connected to a moving rod 5 on the side away from the socket 1, the end of the moving rod 5 away from the socket 1 is made of rubber material, so that the end of the moving rod 5 has plasticity, the side of the moving rod 5 away from the fixed block 4 is fixedly connected to a plug block 7, the plug block 7 is plugged into a plug board 8, and the plug board 8 is fixedly connected to a clamping frame 9 on the side away from the plug block 7;

[0022] By adopting the above technical solution, the clamping frame 9 is composed of two arc-shaped plates, and the two arc-shaped plates are plugged into each other, and the screw rod 10 is threadedly connected on both sides of the clamping frame 9. One side of the screw rod 10 is rotated to connect the clamping plate 11, and the clamping plate 11 clamps the optical fiber line 3. By rotating the screw rod 10, the screw rod 10 drives the clamping plate 11 to move, so that the clamping plate 11 clamps the optical fiber line 3, thereby fixing the optical fiber line 3.

[0023] By adopting the above technical solution, the clamping plate 11 is arc-shaped, and one side of the clamping plate 11 is in close contact with the optical fiber 3, so that the clamping effect of the clamping plate 11 is better, which is conducive to the limited clamping of the optical fiber 3.

[0024] By adopting the above technical solution, in order to make the connection between the optical fiber line 3 and the plug 2 more stable, a slot 81 is provided at the lower part of the plug plate 8 near the plug block 7 on the same side, the plug block 7 is plugged into the slot 81, the plug 7 and the slot 81 are both triangular, the plug 7 and the slot 81 are adapted, and the connecting plate 6 is fixedly connected to the middle of the moving rod 5, the connecting plate 6 is fixedly connected to the tension spring 61 near the side of the fixed block 4, and one end of the tension spring 61 is fixedly connected to the fixed block 4. The moving rod 5 drives the plug block 7 to move, so that the plug block 7 is plugged into the slot 81, and the tension spring 61 is stretched to provide tension to the clamping frame 9 and the clamping plate 11 installed on the plug plate 8, so that the clamping plate 11 always transmits tension to the clamped optical fiber line 3, so that the optical fiber line 3 has a tendency to always be close to the plug 2, thereby improving the stability of the connection.

[0025] By adopting the above technical solution, the fixing block 4 is rotatably connected to the threaded rod 12 near the socket 1, the threaded rod 12 is threadedly connected to the connecting frame 13 near the socket 1, and one side of the connecting frame 13 is fixedly connected to the side wall of the socket 1. Through the fixed block 4, the threaded rod 12 and the connecting frame 13 structure, the connection between the plug 2 and the socket 1 is limited by the connection between the threaded rod 12 and the connecting frame 13, thereby ensuring the stability of the connection between the plug 2 and the socket 1.

[0026] The implementation principle of the optical fiber locking device for optical fiber coupling of the present application embodiment is as follows: first, two arc-shaped plates are placed on both sides of the optical fiber line 3 to form a clamping frame 9, and then the optical fiber line 3 is connected to the plug 2, and then the plug 2 is moved close to the socket 1, and then the threaded rod 12 on one side of the fixing block 4 is rotated to make the threaded rod 12 rotate and enter the connection frame 13, so that the plug 2 is connected to the socket 1, and is limited after the threaded rod 12 is connected to the connection frame 13, and then the screw rod 10 is rotated to make the screw rod 10 drive the clamping plate 11 on one side to move, and make the clamping plate 11 close to and clamp the optical fiber line 3, so that the optical fiber line 3 is fixed, and then the moving rod 5 is pulled to make the moving rod 5 drives the connecting plate 6 to rise and stretches the tension spring 61, then slightly pulls the rubber part on the upper part of the moving rod 5, so that it drives the plug block 7 to tilt, and then continues to pull the moving rod 5 until the plug block 7 is aligned with the slot 81 of the plug plate 8, then releases the moving rod 5, so that the plug block 7 is restored and inserted into the slot 81, so that the plug block 7 is plugged with the plug rod 8, so that the tension spring 61 always provides a pulling force to the plug block 7, and due to the connection relationship, the pulling force will also act on the clamping frame 9 on the plug rod 8, so that the clamping frame 9 and the clamping plate 11 provide a pulling force to the optical fiber line 3, so that the optical fiber line 3 always has a tendency to approach the plug 2, thereby improving the stability of the connection between the optical fiber line 3 and the plug 2.
