PURPOSE:To suppress the phenomenon of an optical fiber core pulled to the cable side, by bringing the optical fiber core into close contact with a cable anchor body, which fixes a center tensile strength wire, by a composite structure body consisting of a rubber member and a metallic body. CONSTITUTION:A center tensile strength wire 1 is inserted through a center tensile strength wire through hole 26 of an optical fiber core supporting body 21 and is fixed by a sleeve 13, and optical fiber cores 2 are inserted through core through holes 27. Plural rubber round tubes 22 and metallic round tubes 23 are inserted to cores 2 and are constricted in through holes 27 by metallic nuts 24, and then, rubber round tubes 22 compress cores 2 uniformly to bring cores 2 closely into contact with the core supporting body 21. Consequently, cores 2 are not pulled to the cable side when a tensile force is applied to the cable, and cores 2 are not returned into a pressure-proof round tube 7 when the tensile force is released, and it is unnecessary to provide a looseness of cores in an excess length processing body, and thus, the connection part and the anchor part are made small-sized and economical, and the workability is improved. |
