Traction assembly, optical fiber connector, manufacturing method for optical fiber connector, and assembly method for optical fiber connector

Abstract

The invention discloses an optical fiber connector, and the connector comprises a housing and an integrated-type plug core assembly. The periphery of a tail handle of a plug core is provided with N positioning keys, wherein N is equal to or greater than two. N positioning keys are arranged at equal-angle intervals at the periphery of the tail handle, and one positioning key, which is corresponding to an eccentric azimuth of an optical fiber in the plug core, is removed, thereby forming a cut part. The housing is provided with (N-1) positioning grooves corresponding to the (N-1) positioning keys on the tail handle. Moreover, a part, corresponding to the cut part, of the housing is not provided with a positioning groove, thereby enabling the integrated-type plug core assembly to be inserted into the housing only if (N-1) positioning grooves are respectively aligned with the (N-1) positioning keys. Therefore, the connector is convenient to disassemble and assemble on site, and can effectively prevent the plug core assembly of the connector from being assembled in the connector housing at a wrong azimuth angle.

Description

technical field [0001] The invention relates to an optical fiber connector, a pulling assembly, a manufacturing method of the optical fiber connector and an on-site use method of the optical fiber connector. Background technique [0002] In the prior art, when it is necessary to pass an optical fiber connector through a slender pipe, two methods are generally adopted: one is to set a traction piece on the connector housing, and the traction rope is connected to the traction piece, so that it can be dragged The fiber optic connector is passed through the elongated pipe; another method is to directly tie the pulling rope to the fiber optic connector, thereby dragging the fiber optic connector through the elongated pipe. [0003] For the first method, the puller must use special tools to assemble to the fiber optic connector. Therefore, it can only be directly assembled to the fiber optic connector at the factory and sold together with the fiber optic connector. Moreover, when ...

Problems solved by technology

However, in the on-site working environment, the on-site operators are easy to ignore this problem, and it is easy to install the ferrule assembly on the housing in the wrong orientation, causing the eccentric orientation of the optical fiber in the ferrule assembly to not be in the predetermined orientation of the housing , which will cause an increase in insertion loss when two fiber optic connectors are mated
