General type optic fibre expands restraints connector

The utility model relates to a general type optic fibre expands restraints connector, including ordinary connector parts, metal caudal peduncle, the ceramic contact pin of taking the step, socket typefiber lens, metal caudal peduncle's one end is gone into to the high step end pressure of pottery contact pin, forms an independent contacting optical fiber spare, the low step pot head of pottery contact pin has socket type fiber lens, the bare fibre is inserted in ceramic contact pin, and optic fibre is even as an organic whole with ceramic contact pin, transparent UV glues and scribbles aroundceramic contact pin, also coats transparent UV at the fiber end face and glues, the fiber end face of pottery contact pin and socket type fiber lens's convex lens in close contact with, connector parts and the assembly of contacting optical fiber spare, ceramic contact pin stretches out the connector parts. The outer diameter of the low step end of pottery contact pin is less than socket type fiber lens's internal diamete
