Problems solved by technology

[0005] In the aforementioned optical fiber connectors in the prior art, the number of independent components included in the optical fiber connector is relatively large, and the structure is also very complicated, which is not convenient for quick installation of the optical fiber connector on site, and it is very time-consuming to assemble the optical fiber connector on site
[0006] Moreover, in the prior art, due to the need to use a longer extension tube, this will cause the overall length of the optical fiber connector to be too long, and the length of the stress buffer boot to be too short, which will cause the optical cable connected to the optical fiber connector to be Susceptible to damage when subjected to lateral pull, i.e., reduces the ability of the cable to resist lateral loads
[0007] In addition, in the prior art, it is necessary to use a special crimping tool to crimp the crimping sleeve or the stress buffer shoe on the rear end of the extension tube, which increases the difficulty of assembling the optical fiber connector on site

Abstract

The invention discloses an optical fiber connector comprising an outer housing, an inner housing, a core-inserting assembly, and a spring. The inner housing is disposed in the outer housing. The core-inserting assembly is accommodated in the inner housing, and comprises a core-inserting body and a preset optical fiber disposed in the core-inserting body. The spring is accommodated in the inner housing, and is disposed on the rear part of the core-inserting body, and is used to apply the preset axial force to the core-inserting body. The inner housing comprises a front body and a rear body, and the rear body is disposed on the front body. The spring is disposed between the rear body and the core-inserting body in a compressed manner. According to the invention, the rear body can be used as the retainer for compressing the spring and the extension pipe for fixing the Kevlar fiber of the optical cable, and therefore compared to the prior art, the number of the parts of the optical fiber connector can be reduced, the structure of the optical fiber connector can be simplified, and the on-site quick assembly of the optical fiber connector can be facilitated.

Description

technical field [0001] The invention relates to an optical fiber connector and an on-site assembly method of the optical fiber connector. Background technique [0002] In the prior art, a fusion-type optical fiber connector connected to one end of an optical cable through optical fiber fusion generally includes an inner housing, an outer housing, a ferrule assembly, a spring, a spring retainer, an optical cable fixing assembly, and a protective cover for a fusion point tubes, strain relief boots and dust caps. The aforementioned ferrule assembly includes a ferrule and a section of preset optical fiber held in the ferrule, and the preset optical fiber is used for heat fusion with the incoming optical fiber of the optical cable. [0003] In the prior art, when assembling optical fiber connectors on site, it is necessary to install the dust cap, ferrule assembly, spring and spring retainer into the inner housing one by one; Splice together; then splice the fusion point protec...
