Problems solved by technology

[0006] 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
[0007] 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
[0008] 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. The optical fiber connector comprises an inner shell, an insertion core assembly and a spring; the inner shell is provided with a precursor; the insertion core assembly is accommodated in the inner shell and comprises an insertion core and a section of preset optical fiber which is maintained in the insertion core in advance; the spring is located behind the insertion core and used for applying predetermined axial force to the insertion core and pushing and pressing the insertion core into the inner shell in advance, the insertion core assembly and the spring are maintained in the precursor in advance, and a preset optical fiber is used for being fused with an introduction optical fiber of an optical cable. By means of the optical fiber connector, the number of parts of the optical fiber connector is reduced, the structure of the optical fiber connector is simplified, and the optical fiber connector is conveniently and quickly assembled on spot.

Description

[0001] This application is a divisional application of a Chinese patent application (patent application number: 201410502692.X) submitted on September 26, 2014. technical field [0002] The invention relates to an optical fiber connector and an on-site assembly method of the optical fiber connector. Background technique [0003] 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. [0004] In the prior art, when assembling optical fiber connectors on site, it is neces...
