Universal fiber expanding connector and production process thereof

Abstract

The invention relates to a universal fiber expanding connector and a production process thereof; the universal fiber expanding connector comprises a common connector umbrella part, a metal tail stem,a stepped ceramic insert and a sleeve-type fiber lens; a high-step end of the ceramic insert is pressed into one end of the metal tail stem, forming an independent fiber contactor; a low-step end of the ceramic insert is sleeved with the sleeve-type fiber lens; bared fibers are inserted into the ceramic insert and are integrally connected with the ceramic insert; transaprent UV (ultraviolet) glueis applied to the periphery of the ceramic insert, and the end faces of the fibers are also coated with transaprent UV glue; the fiber end face of the ceramic insert is in tight contact with a convexlens of the sleeve-type fiber lens; the common connector umbrella part is fitted to the fiber contactor, and the ceramic insert is extended out of the common connector umbrella part. The outer diameter of the low-step end of the ceramic insert is less than the inner diameter of the sleeve-type fiber lens, and the outer diameter of the sleeve-type fiber lens is less than the maximum outer diameterof the high-step end of the ceramic insert.

Description

technical field [0001] The invention relates to a general-purpose optical fiber beam expander connector, which belongs to the technical field of optical fiber connectors. Background technique [0002] At present, fiber optic connectors for silica fibers can be divided into three categories: [0003] 1. Traditional single-core or multi-core fiber optic connectors: [0004] They are usually completed through processes such as fiber stripping, glue injection, curing, and grinding. In order to eliminate the non-Nier reflection effect of optical fiber butt joints, the spring inside the connector housing squeezes the single-core or multi-core optical fiber ferrule, and finally realizes the optical fiber tight fit butt. This type of traditional connector has fixed processing technology, high maturity, small insertion loss, controllable return loss, and low processing cost. It is currently the most important processing method, with a market share of more than 95%. However, this ty...

Problems solved by technology

This kind of connector is difficult to install, usually using a multi-dimensional adjustment frame and comprehensive adjustment of light source optical power, the production efficiency is low, the process is cumbersome, the production cost remains high, and the one-time pass rate of the product is not high. The above reasons are caused by beam expansion. An important reason why fiber optic connectors cannot be popularized on a large scale. The principle is as follows: image 3 shown
