Description

Technical Field

[0001] This utility model belongs to the technical field of fiber optic connectors, specifically, it relates to a UV-cured polishing type fiber optic connector. Background Technology

[0002] Fiber optic connectors are devices used for detachable connections between optical fibers. Their main function is to precisely align the two end faces of the optical fibers to ensure that the light energy output from the transmitting fiber is coupled to the receiving fiber to the maximum extent possible, while minimizing the impact on the fiber optic communication system. Fiber optic connectors primarily utilize the principle of total internal reflection to transmit light from one optical fiber to another. The main components of a fiber optic connector are two precisely aligned end faces of the optical fibers, which transmit light from one fiber to another through physical contact. Existing fiber optic connectors are first fixed with adhesive, then clamped using two semi-cylindrical structures. These semi-cylindrical structures have external threads on the outside, which are used with nuts for locking. During use, the nuts are prone to loosening due to movement or vibration, and the adhesive curing time between the fiber and the connector is relatively long, affecting the installation efficiency of the fiber optic connector.

[0003] In view of this, this utility model is proposed. Utility Model Content

A cable clip 4 is provided on the outer side of one end. A locking slot 17 is provided on the outer side of the end of the cable clip 4 that is connected to the tail shank 6. An open end slot 18 is provided at the center of the end face of the cable clip 4. A mating block 9 is provided on the tail shank 6. The position and specifications of the mating block 9 correspond to the locking slot 17. A plug-in mating end 15 is provided on the end of the cable clip 4 that is away from the open end slot 18. A convenient insertion ring slot 16 is provided on the side of the plug-in mating end 15. The plug-in mating end 15 and the tail sleeve 2 are mated. The cable clip 4 is used to fix the optical fiber 7.

[0024] Both the cable clip 4 and the outer shell 5 are made of transparent material. The end of the insertion mating end 15 is a conical structure. There are two insertion ring grooves 16.
