<p>PROBLEM TO BE SOLVED: To make a part of a jumper wire gripped by a pair of gripping pieces as short as possible by applying to the gripped part of the jumper wire a collar divided into two parts along the spiral of a fin with the fin put between the two divided parts of the collar. SOLUTION: A jumper wire is gripped between a pair of gripping pieces through a collar 4a, 4b which are divided into two parts in the longitudinal direction corresponding to the spiral of a spiral fin 2a, 2b. In other words, the collar parts 4a, 4b are so put on a jumper wire 2a that they may hold the wire between them with the fin 2b lying in the middle and then the wire provided with the collar 4a, 4b is held between a pair of the gripping pieces and is tightened with bolts and nuts. By this method, the collar 4a, 4b can be easily put on the jumper wire 2a and at the same time, the collar 4a, 4b can be perfectly fit in with the fin 2a. Furthermore, a length of the gripped part of the jumper wire 2a can be shortened and thereby a curvature of the jumper wire 2a can be effectively met.</p> |
