Claims

[Claims for Utility Model Registration] An optical protector plug comprising a case, an inner sleeve, a coil spring, and a ferrule, wherein the case is made by dividing a cylindrical body made of synthetic resin into two along its axis. It consists of a first case and a second case, each of which has a convex portion and a concave portion that engage with each other on the dividing surfaces of the first and second cases. A cord storage chamber and a ferrule storage chamber are respectively formed in communication with the opening at the end, and a ring-shaped recess is formed on the inner peripheral surface of the cord storage chamber, and the ring-shaped recess and the opening at one end of the case are connected to each other. Screw-shaped concave portions and convex portions are alternately formed between the ferrules, and the ferrules are attached to the tip of the core wire at the end of the optical fiber cord, and the ferrules are attached to the ferrule storage chamber together with the coil springs wound around themselves. and is elastically pressed against an end surface of the ferrule housing chamber by the coil spring, with one end of the ferrule protruding outside from openings at other ends of the first and second cases, and the inner sleeve A cylindrical body made of metal and having a flange at one end, the outer circumferential surface of which has a screw-shaped convex portion and a concave portion that respectively oppose the concave portion and convex portion formed in the cord storage chambers of the first and second cases. The optical fiber cords are formed alternately and are inserted in a wedge shape between the core wires of the ends of the optical fiber cords and the tension members, and are press-fitted together with the optical fiber cords into the cord storage chambers of the first and second cases, and the inner An optical connector plug, characterized in that a flange of the sleeve is fitted into a ring-shaped recess of the cord storage chamber.
