Problems solved by technology

[0008] But, for this existing SC-APC optical fiber connector, when cleaning the end face of the ferrule assembly of the optical fiber connector, it is easy to cause the end face of the ferrule assembly to rotate at a large angle, causing loss to increase accordingly, and when the ferrule Excessive component rotation will cause the problem of incorrect intermating between SC-APC fiber optic connectors

Abstract

Disclosed in the invention is an optical fiber connector comprising a ferrule assembly, a crimping body sleeved at the ferrule assembly, and a housing. The ferrule assembly and the crimping body are installed in the housing. The crimping body and the housing are configured to be maintained at a first mounting position and a second mounting position mutually. At the first mounting position, the ferrule assembly can be separated from the housing and can rotate relative to the housing; and at the second mounting position, the ferrule assembly is connected with the housing and can not rotate relative to the housing. Therefore, at the first mounting position, end surface grinding of the non-inclination plane of the ferrule assembly and ferrule assembly angle adjustment can be carried out; and at the second mounting position, oblique angle end surface grinding of the ferrule assembly can be carried out and ferrule assembly rotation can be prevented when the connector end surface is cleaned. According to the invention, the technical scheme can be applied to different production phases of the connector; and reliability of the connector can be ensured. In addition, the invention also provides manufacturing and assembling methods of the optical fiber connector.
