Abstract

Abstract Disclosed is an optical switching connector including a ferrule plate, which fixes an end of an optical fiber to a predetermined position, has pin grooves formed in parallel at its both ends, and has at least one of its pin grooves formed to a width enabling horizontal movement of a reference pin, pin holding members which position the reference pin in said pin grooves, and a frame body which houses said ferrule plate and pin holding members. The optical switching connector is characterized in that the pin holding members are provided individually for each pin groove and provision is made at the both sides of the pin grooves of members for pressing the pin holding members corresponding to the pin grooves where the reference pins can move horizontally to the ferrule plate.
