Abstract

An anti-loose FC type optical fiber connector comprises a plug and a socket, ceramic insertion cores are coaxially embedded in the plug and the socket, optical fibers are embedded in the ceramic insertion cores, the plug comprises a middle shell and a connecting nut, the connecting nut is arranged outside the socket in a sleeving mode and is in threaded connection with the socket, the ceramic insertion cores are located in the middle shell, and the ceramic insertion cores are located in the middle shell. The middle shell is sleeved with the connecting nut, and an anti-loosening assembly is arranged between the middle shell and the connecting nut and comprises a movable ratchet wheel, a fixed ratchet wheel and an elastic piece. Through the innovative design of the plug and socket structures, a plug-adapter flange-plug three-section structure of a common FC connector is changed into a plug-socket two-section structure, so that the length and the size of the connector are reduced, the installation of the connector is facilitated, the reliability of the connector is improved, and the miniaturization design is realized.

Description

technical field [0001] The invention relates to the technical field of optical fiber connectors, in particular to a loose-proof FC optical fiber connector. Background technique [0002] The FC type optical fiber connector is the most widely used general-purpose optical fiber active connector in the optical fiber transmission system. It is an important component in the optical link and is used to realize the transmission of optical signals between devices. With the development of optical fiber broadband technology, optical fiber active connectors are more and more widely used, and the working environment used is also increasing, and at the same time, it is becoming more and more harsh. [0003] At present, the mechanical use conditions of FC fiber optic connectors are increasing, but the reliability requirements for optical signal transmission of the connectors have not been reduced, mainly in the following aspects: [0004] 1. FC fiber optic connectors are usually used in s...
