LC type polarization-maintaining connector

Abstract

The invention discloses an LC type polarization-maintaining connector, and relates to the field of optical fiber connectors, the LC type polarization-maintaining connector comprises an outer frame sleeve and an insertion core assembly in sliding fit with the outer frame sleeve, an integrated tail sleeve is arranged at the tail end of the outer frame sleeve, an angle fixing ring is arranged at one end, close to the insertion core assembly, of the integrated tail sleeve, one end of the insertion core assembly is in sliding fit with the angle fixing ring, the insertion core assembly, the angle fixing ring and the integrated tail sleeve are communicated to form an optical fiber channel for an optical fiber to pass through, and a spring used for applying acting force away from the angle fixing ring to the insertion core assembly is arranged in the outer frame sleeve; the integrated tail sleeve comprises a positioning part located at one end close to the angle fixing ring and a flexible part located at the other end, the flexible part and the positioning part are integrally formed, and the positioning part is clamped to the inner side of the tail end of the outer frame sleeve through an inner buckle structure. The integrated tail sleeve has the advantages that the situation that the integrated tail sleeve is loosened due to pressure is reduced, and the stability of the integrated tail sleeve is improved.

Description

technical field [0001] The invention relates to the field of optical fiber connectors, in particular to an LC type polarization maintaining connector. Background technique [0002] In the field of optical communication, optical fiber connectors are connecting devices for connecting optical fibers. Through the connector, the optical energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent, and the impact on the system due to its intervention in the optical link can be minimized. The fiber optic connector cannot be used alone, it must be intermatched with other connectors of the same type to form the connection of the optical path. [0003] LC type polarization maintaining connector is a kind of optical fiber connector, which is used to connect optical fibers and is widely used in integrated wiring system engineering. [0004] In the related art, in order to protect the end of the optical fiber relative to the connector, so that the...

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that in the process of actual use, the tail sleeve is only connected to the connecting pipe by its own elasticity, the connection stability is limited, and there is a probability of loosening when it is under pressure. Therefore, There is room for improvement
