Claims

[Claims for Utility Model Registration] Consisting of a central tensile strength member, a plurality of optical fiber cores arranged along the outer periphery of the central tension member, and an outer sheath wrapped around the outer periphery around which the plurality of optical fiber cores are arranged. In the optical cable retaining terminal section of the optical fiber cable terminal section that converts the plurality of optical fiber cores of the optical fiber cable into a single-core optical cord, the end section of the optical fiber cable 1 that is converted into a single-core optical cord is connected to one side. an insertion section 10 that is inserted from the end of the optical fiber cable and fixed therein, and the central tensile member 2 whose outer sheath of the optical fiber cable inserted through the insertion section 10 is removed to expose the optical fiber core wire and the central tensile member 2. a gripping metal fitting 12 that is inserted through the central tensile strength body 2 to grip it and caulked to fix the end of the central tensile strength body 2; a collar part 11 that is attached and fixed to the gripping metal fitting 12; and the collar part 11 and the insertion part 10. a plurality of support rods 13 for fixing; a metal casing 14 having a protrusion 17 on its outer surface that is attached and fixed to one end of the insertion section 10; and a metal casing 14 attached to the other end of the metal casing 14 to fix,
An optical cable retaining terminal section comprising a metal housing end section 16 having an optical cord lead-out hole 15 from which the optical cord 5 having the plurality of optical fibers inserted into the reinforcing cord is pulled out.
