Claims

[Claims 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 an outer sheath, and the core wire of the optical fiber cord is penetrated and held. At the same time, when connecting to a cylindrical optical connector having a fixing part at the rear end with a diameter smaller than other parts, the cylindrical support member covers the fixing part via the tension member, and the cylindrical support member covers the fixing part via the tension member. In the tension member/sheath fixing structure of an optical connector, the tension member and the sheath are fixed by covering the periphery of the cylindrical support member with a fixing ring through the sheath, wherein the entire inner circumferential surface of the cylindrical support member is fixed. is provided with a large number of tension member protrusions, and an outer cover protrusion for hooking the outer cover on one end of the outer circumferential surface, and the fixing ring is press-fitted at one end with the outer diameter of the cylindrical support member. A large diameter portion is provided, and the cylindrical support member is press-fitted into a fixing portion of an optical connector that covers and evenly spreads the tension member of the optical fiber cord, and the outer sheathing protrusion of the cylindrical support member is press-fitted. Stretch out the jacket and hang it on the
The periphery is press-fitted with the large diameter part of the fixing ring, and the tension member is connected to the fixing part of the optical connector and the tension member protrusion on the inner circumference of the cylindrical support member, and then the tension member is attached to the outer cover of the cylindrical support member. A tension member and outer sheath fixing structure for an optical connector, characterized in that the outer sheath is fixed by being held between a protrusion and a large diameter part of a fixing ring.
