<p>PROBLEM TO BE SOLVED: To execute connection at a branch side in any direction around the axis of an aluminum clamp by forming the electrical connection surface treatment of the aluminum clamp with a branch-side socket with a circumferential surface. SOLUTION: An anchoring clamp sets an aluminum sleeve 2' on a steel clamp 1', when a steel core is subjected to compression connection. At that time, a cylindrical part with an electrical connection surface 2b' covers a steel clamp corrugated part 1b'. At the same time an aluminum standed pair is compressed at a compression part 2a' and is compressed and is formed in one piece also on a steel clamp. At this time, the steel core aluminum stranded wire has a non-circular section and has irregularities, so that if forms non-linear sectional inrregularities on the inner surface of the compression part 2a' of the aluminum clamp also. Therefore, the aluminum clamp 2' is inserted into the stranded wire, while being rotated according to the stranding pitch of the stranded wire, namely the pitch of the irregularities. In the this manner, the aluminum clamp is rotated due to, for example, the stranding pitch of an electric wire, thus connecting the socket at the branch side at any position.</p> |
