Optical fiber connector and tail wiring assembly thereof

Abstract

The invention provides an optical fiber connector and a tail wiring assembly thereof, and can solve the problems that an optical fiber is easily scratched and damaged with the inner wall of an existing optical fiber connector during assembly, and the reliability and the percent of pass are low due to the fact that optical signal transmission is affected by chippings generated by scratching. The tail wiring assembly comprises a main shell and an optical cable fixing piece; a fiber protection sliding sleeve is assembled with the optical cable fixing piece in an inserting and sleeving manner; thefiber protection sliding sleeve is provided with an extension position and a retraction position relative to the optical cable fixing piece; when in the extending position, the optical fiber fixing piece and the optical cable fixing piece jointly enclose a fiber protection space; when in the retraction position, the optical fiber can extend out of the front end of the optical fiber protection sliding sleeve; the fiber protection sliding sleeve and the optical cable fixing piece are in sliding resistance fit in the direction of a plug bush so as to keep relative fixation when no external forceis applied to the two; a stop structure is arranged in the inner cavity of the main shell and can be matched with the front end of the fiber protection sliding sleeve in an abutting mode to enable the fiber protection sliding sleeve to overcome the sliding resistance acting force with the optical cable fixing piece to retract; and the main shell is also provided with an opening for the optical fiber to extend out of the main shell.

Description

technical field [0001] The invention relates to an optical fiber connector and a tail wiring assembly thereof. Background technique [0002] The scheme of using optical fiber to transmit optical signals is widely used and mature, and because the positions of the two modules connected by optical fiber are uncertain, technicians arrange the optical fiber on site according to the distance between the two modules, and then connect the optical fiber connector with the The optical fiber is assembled and connected, and finally the optical fiber connector is inserted into the module. Existing optical fiber connectors are formed by nesting and combining multiple parts. For example, an optical cable connector disclosed in a patent document with the authorized announcement number CN207851354U and the authorized announcement date of 2018.09.11 includes a single butt joint housing. The front cover and the simplex back cover, and the ferrule assembly installed in the housing, the ferrule...
