Claims

[Claims for Utility Model Registration] 1. A conduit aerial cable in which the distal end of an outer sheath and the distal end of an inner sheath are overlapped for a predetermined length to form an overlapping part, and a backing is interposed between the overlapping part. In the sheath connection part, a backing retaining part is provided between the overlapping parts, a packing is engaged with the backing retaining part, the backing is pressed by a press ring disposed on the outer periphery of the inner sheath, and the press ring is pressed against the inner sheath. A conduit aerial cable sheath connection part, characterized in that the connection part is welded to the outer periphery, and the end face of the outer sheath is welded to the outer periphery of a push ring or the outer periphery of the inner sheath. 2. The conduit aerial cable sheath connection part according to claim 1, wherein the backing retaining part is the diameter-expanded inclined inner surface of the diameter-expanded outer sheath. 3. The conduit aerial cable sheath connection part according to claim 1, wherein the backing retaining part is a groove provided in the inner sheath. 4. The conduit aerial cable sheath connection part according to claim 1, wherein the backing engagement part is an enlarged diameter inclined outer surface of the inner sheath with enlarged diameter.
