Optical fiber connector integrated with a plurality of rectangular multi-core optical fiber contact pins and integrated connector

Abstract

The present invention provides an optical fiber connector integrated with a plurality of rectangular multi-core optical contact pins and an integrated connector. The connector comprises a connector casing which is provided with contact pin installation channels that extend from the incoming end of the optical fiber to the insertion end and a plurality of parallelly equipped rectangular multi-core optical fiber contact pins. Each contact pin installation channel is provided with a spring stopping structure and a spring which is provided between the spring stopping structure and the contact pin with a contacting mode. The connector casing is inserted and fixed with a press plate. Each contact pin installation channel comprises a corresponding front part and a corresponding back part which are respectively installed in the casing and the press plate. The press plate is provided with a back end plane which is installed at the back end of the connector casing. Furthermore the back end plane is provided with an optical fiber insertion opening communicated with the back part of the contact pin installation channel. The spring stopping structure is provided in the back part of the contact pin installation channel in the press plate. The optical fiber connector of the invention has the advantages of: compact structure of contact pin fixing structure, strong wholeness and suitability for the fast pulling-inserting occasion.

Description

technical field [0001] The invention relates to an optical fiber connector, in particular to an optical fiber connector and an integrated connector for integrating a plurality of rectangular multi-core optical fiber ferrules. Background technique [0002] The diameter of the optical fiber is extremely small, even after the protective layer is added, the diameter is only 250 microns. Hundreds of optical fibers can be placed in a single optical cable, and the use of connectors to terminate these optical fibers will increase the occupied space to 20 to 50 microns. times, this is due to the fact that the volume of the fiber optic connector must at least be able to be held by hand, and a sufficiently stable optical coupling and holding device also takes up some space. In order to increase the fiber density in the connector, a combination of multiple fibers Multi-core fiber ferrules into one ferrule, such as MT, MPO series of rectangular multi-fiber fiber ferrules, each MT / MPO fer...

AI Technical Summary

Problems solved by technology

The fixing structure of the pin assembly unit in the housing is realized through the engagement of the shoulders on the rectangular pins and the spring keys of the corresponding push-in mechanisms with the corresponding installation cavity and the axial tightening of the spring. The spring can provide a pressing force on the insertion end face of the pin during insertion, and when the insertion force is too large, the compressed pin can be elastically retracted and released in the axial direction to provide overstress protection. This pin assembly The fixed structure needs to provide multiple push-in mechanisms with the same number as the number of pins and optical cables to act on the housing respectively. The structure and processing technology are more complicated, and the shell thickness of each push-in mechanism will directly affect the installation cavity and the housing. size, which is not conducive to the realization of small volume and high density installation
