Claims

[Scope of Claim for Utility Model Registration] An optical fiber cord in which a core wire and a tension member built in in the longitudinal direction of the cord are exposed at a predetermined length from the tip of the outer sheath, and the core wire of the optical fiber cord is passed through the cord. At the same time, a cylindrical optical connector having a fixing part with a smaller diameter than the other parts at the rear end is attached to the fixing part via a tension member from a fixing ring with an outer diameter approximately equal to that of the optical connector. In the tension member fixing structure of an optical connector, which is fixed by press-fitting into the optical connector, a ring-shaped groove is provided near one end of the fixing part of the optical connector to serve as a tension member fixing part and a jacket fixing part, and a plurality of ring-shaped grooves are provided on the outer circumferential surface. a cylindrical part having a protrusion, and a plurality of folded pieces that are bent outward from one end of the cylindrical part and have windows on the base side of the bent part for penetrating the tension member, forming a cylindrical support member that fits with the tension member fixing part; and providing a small diameter part at the rear end of the fixing ring that press-fits with the jacket fixing part; A plurality of tension members are fitted into the tension member fixing portion and passed through the window portion of each folded piece in a bundle, and the outer sheath of the optical fiber cord is stretched to cover the outer sheath fixing portion of the fixing portion. and a tension member is sandwiched between the cylindrical portion of the cylindrical support member and the folded piece by caulking or press-fitting a fixing ring so as to cover the outer peripheral surface of the connector. tion member fixed structure.
