Abstract

A coupling member for receiving wire strands of a stranded composite core conductor includes a substantially cylindrical body having first and second ends. A first through hole extends from a first opening at the first end to a second opening at the second end of the body for receiving a wire strand of the stranded conductor. A first protrusion extends axially outwardly from the first end of the body. A first recess in the second end of the body is adapted to receive a protrusion of an adjacent coupling member.

First claim
