OPTICAL CONNECTOR, METHOD OF SETTING PROTRUDING LENGTH OF OPTICAL FIBER OF THE OPTICAL CONNECTOR, AND JIG THEREFOR

摘要

An optical connector which correctly sets a protruding length of an optical fiber (5) protruding from a connection end face (16) of a ferrule (1), a method of setting the protruding length of the optical fiber of this optical connector and a jig therefor are described. A recessed surface (33) is formed in a ferrule receiving surface (32). The depth of the recess surface (33) is set to be equal to the protruding length of the optical fiber (5) protruding from the connection end face (16) of the ferrule (1). The ferrule (1) is clamped by ferrule clamping members (35a and 35b) and is pressed to the ferrule receiving surface (32) by the urging force of a compression spring (36). An optical fiber core wire (3) is passed through the ferrule (1), is allowed to protrude from the connection end face (16) of the ferrule (1) and is butted against the recess surface (33). The optical fiber core wire (3) is clamped by a core wire clamping member (41), which is urged toward the ferrule receiving face (32) by the urging force of a compression spring (42) so that the distal end of the optical fiber (5) is brought into pressure contact with the recess surface (33). An adhesive is charged under this state into an adhesive charging hole (43) of the ferrule (1) so as to bond and fix the optical fiber (5) to the ferrule (1), and an optical connector whose optical fiber (5) is allowed to protrude by a predetermined length from the connection end face (16) can be obtained.
