Optical fiber connector for field construction

Abstract

The invention provides an optical fiber connector for field construction. The optical fiber connector comprises a connector shell, wherein the front end of the connector shell is a plug-in end, and the rear end of the connector shell is a wiring end; an embedded optical fiber and a mounting sleeve are arranged in the connector shell; an optical cable press-fitting structure is also arranged on theconnector shell and comprises a tail clamp; the tail clamp and the connector shell are assembled together in a circumferential rotation-stopping manner through a circumferential rotation-stopping structure; an elastic arm is arranged on one of the tail clamp and the connector shell; a bulge is arranged on the outer side of the elastic arm; a plug-in part which is in plug-in fit with the bulge toform front and back axial stop fit is arranged on the other of the tail clamp and the connector shell; and the optical cable press-fitting structure also comprises a connecting nut which is spirally assembled at the rear part of the connector shell and is sleeved outside the tail clamp. The tail clamp is fixed relative to the connector shell, so that the connecting optical fiber in the optical cable cannot be twisted during assembly, and the influence on the coupling accuracy of the embedded optical fiber and the connecting optical fiber is avoided.

Description

technical field [0001] The invention relates to an optical fiber connector for on-site construction. Background technique [0002] At present, with the rapid development of optical fiber communication technology, PON technology has become the most important solution for fiber-to-the-home in the world. At present, in the installation and construction of the last mile access, optical fiber fusion splicing technology and rapid optical fiber termination technology are the mainstream solutions. In the rapid optical fiber termination technology, the common ones are straight-through type and pre-embedded type. Due to the limitation of existing technology, the performance of straight-through rapid termination is not stable enough to meet the requirements of rapid construction of optical fiber on site. The existing common one is embedded The formula is quickly completed. [0003] The existing pre-embedded quick-end optical fiber connector is shown in the Chinese invention patent wi...
