Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber adapters, and particularly relates to an optical fiber adapter. Background Technique

[0002] An optical fiber adapter, also known as an optical fiber connector, is a device used to connect two optical fibers. It is the most widely used optical passive device in communication systems. Its principle is to achieve the transmission of optical signals through physical connection, enabling the end faces of two optical fibers to be precisely docked.

[0003] At present, when using an optical fiber adapter, the optical fiber adapter and the optical fiber interface are mostly connected through a clamping structure. This connection method is convenient for the insertion and removal of optical fibers and their replacement. However, the clamping structure has relatively large friction during insertion and removal, and it is inevitable to cause wear to the clamping structure during the insertion and removal process. After severe wear, the connection will become unstable, affecting the optical fiber docking. Currently, the clamping structure of the optical fiber adapter and the housing are an integrated structure. After the clamping structure is worn, the entire optical fiber adapter needs to be replaced, which results in waste of other intact components and increases the replacement cost. Therefore, those skilled in the art have provided an optical fiber adapter to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an optical fiber adapter to solve the following technical problems:

[0005] How to prevent the connection stability from being reduced due to wear of the clamping structure of the optical fiber adapter and reduce the replacement cost.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0008] The clamping mechanism includes a frame. On both sides of the front end face of the frame, clamping feet are fixedly connected. On both sides inside the frame, locking components are arranged.

[0009] The locking component includes an upper chuck and a lower chuck. The upper end of the upper chuck extends out of the upper end face of the frame, and the lower end is fixedly connected with a movable rod. The lower end of the movable rod is fixedly connected with a first rack. The lower end of the lower chuck extends out of the lower end face of the frame, and the upper end is fixedly connected with a second rack that is slidably connected inside the frame.

Two lower card slots are formed in the inner bottom of the housing, and the two lower card heads are respectively clamped with the two lower card slots;

[0011] Further, the locking assembly further includes a support base. One end of the support base is fixed to the inside of the frame, and the other end is slidably sleeved with a movable rod. A spring is sleeved on the outer end of the rod body of the movable rod between the support base and the upper card head;

[0012] Further, support plates are fixed on both sides inside the frame. Matching grooves are formed on the inner sides of the two support plates, and the matching grooves are in contact with the surface of the mounting sleeve;

[0013] Further, two guide grooves are formed on both inner walls of the housing. Two clamping blocks are fixedly connected to both sides of the frame, and the clamping blocks are slidably connected with the guide grooves;

[0017] Advantages of the present utility model:

[0018] In the present utility model, a clamping mechanism separated from the housing is provided. The clamping mechanism can be disassembled. A locking assembly is arranged inside the clamping mechanism. Through the clamping cooperation of the upper card head and the lower card head of the locking assembly with the upper clamping slot and the lower card slot of the housing, the clamping mechanism is stably fixed from the upper and lower directions, with strong stability and high reliability after installation. During disassembly, press the two upper card heads. When the upper card head is unlocked from the upper card slot, the lower card head will also rise synchronously and separate from the lower card slot, thereby unlocking the clamping mechanism and enabling the clamping mechanism to be taken out of the housing. After the clamping mechanism is worn, it can be replaced, ensuring the stability of the optical fiber after connection. Moreover, when replacing, there is no need to replace the entire optical fiber adapter, and other intact components can continue to be used, avoiding waste and reducing the replacement cost.

A clamping mechanism 2 is arranged inside the housing 1. The arranged clamping mechanism 2 is used to clamp and fix the inserted fiber optic structure during fiber optic connection to prevent the interface from loosening after plugging. An installation sleeve 12 is fixed between the two housings 1. A sleeve 13 is fixed inside the installation sleeve 12. The arranged installation sleeve 12 is used to fix the sleeve 13. The arranged sleeve 13 is used to ensure accurate butt-joint of the optical fiber and protect the optical fiber. The material uses zirconia ceramic sleeve commonly used in the prior art.

[0030] The clamping mechanism 2 includes a frame 21. On both sides of the front end face of the frame 21, clamping feet 22 are fixedly connected. On both sides inside the frame 21, locking components 23 are arranged. At the outer end of the provided clamping feet 22, protruding bevel heads are provided, which can cooperate with the fiber optic connector for clamping, so as to clamp and fix the fiber optic interface.

[0031] The locking component 23 includes an upper chuck 231 and a lower chuck 238. The upper end of the upper chuck 231 extends out of the upper end face of the frame 21, and the lower end is fixedly connected with a movable rod 232. The lower end of the movable rod 232 is fixedly connected with a first rack 235. The lower end of the lower chuck 238 extends out of the lower end face of the frame 21, and the upper end is fixedly connected with a second rack 237 that is slidably connected inside the frame 21. A gear 236 is rotatably connected inside the frame 21. The gear 236 is arranged between the first rack 235 and the second rack 237 and is meshed with both of them.

[0032] On the upper end face of the housing 1, two through upper card slots 7 are opened. The two upper chucks 231 are respectively clamped with the two upper card slots 7.
