Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to a docking device for optical fiber connection. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. Fiber optic connectors are required for docking and connecting optical fibers. They precisely dock the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its involvement in the optical link can be minimized.

[0003] The prior art discloses a quick-plug and small-sized high-density optical fiber connector with a publication (announcement) number of CN211505962U, comprising a housing, a mounting plate, an optical fiber and a docking optical fiber. The utility model has a simple and reasonable structural design. When working, the optical fiber and the docking optical fiber are first inserted into the housing, the first mounting plate and the second mounting plate, and the ends of the optical fiber cores are extended through the block and connected through matching liquid to prevent dust and moisture in the air from affecting the use of the connector; a manual lever moves the slider toward the center, thereby moving the connecting rod and the clamping block toward the center, and clamping and fixing the optical fiber and the docking optical fiber to prevent the optical fiber and the docking optical fiber from moving during use; optical fibers and docking optical fibers of different diameters are clamped and fixed through the clamping block, thereby improving the usability of the device.

[0004] The above utility model utilizes a lever to drive the movement of a slider, a connecting rod and a clamping block, and cooperates with the elastic force of a first spring to achieve limited fixation of the optical fiber that needs to be docked. However, the lever connecting the slider will cause the inner cavity of the first mounting plate and the second mounting plate to be connected to the outside world, which may easily lead to the entry of external dust and moisture, thereby affecting the use effect of the optical fiber. In addition, during use, foreign objects touching the lever movement may easily cause the docked optical fiber to loosen, thereby affecting the docking connection effect of the optical fiber. The practicality is relatively general. Utility Model Content
