Claims

[Scope of utility model registration request]

(1) On the outer periphery of the optical fiber composite overhead ground wire, a plurality of helical molded armors with an outer diameter larger than the diameter of the strands of the overhead ground wire are attached.
1. A compression type connection part for an optical fiber composite overhead ground wire, characterized in that a rod is tightly wound, and an aluminum clamp is placed on the outside of the armor rod to compress it.

(2) The compression type connection portion of an optical fiber composite overhead ground wire according to claim 1, wherein the spirally molded armor rod has a circular or ladder-shaped cross section.

(3) The compression type connection part for an optical fiber overhead ground wire according to claim 1 or 2, wherein the aluminum clamp is of a two-piece type.
