CONNECTION METHOD FOR COMPOSITE CONDUCTOR WIRE, CONNECTION DEVICE, CONDUCTOR HOLDING MEMBER AND CONNECTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a connection method for a composite conductor wire capable of reducing an eddy current loss and further connecting the composite conductor wire in a satisfactory state where secure conductivity is kept, a connection device, a conductor holding member and a connection structure.SOLUTION: While abutting connection allowance parts 40 of a composite conductor wire 12A, the composite conductor wire is held between conductor holding parts 72A in an electrode 71A or when the composite conductor wire is inserted into a conductor insertion groove 74B of a conductor holding part 72B in an electrode 71B, the conductor holding parts 72A and 72B are prevented by contact avoidance grooves 73A and 73B from being brought into contact with a low fusion point conductor 30. A high fusion point conductor 20 and the low fusion point conductor 30 having different fusion points are substantially simultaneously fused at a temperature corresponding to the fusion points of the conductors 20 and 30, and the composite conductor wires 12A are connected in the satisfactory state where secure conductivity is kept, while abutting the same type of the high fusion point conductors 20 and the low fusion point conductors 30 in the connection allowance parts 40.SELECTED DRAWING: Figure 2 【課題】この発明は、渦電流損失を低減することができるうえ、確実な導電性が確保される良好な状態に接続することができる複合導体線の接続方法、接続装置、導体挟持部材、及び接続構造体の提供を目的とする。【解決手段】複合導体線１２Ａの接続許容部４０同士を突き合わせたまま、電極７１Ａにおける導体挟持部７２Ａ間に挟持するか、電極７１Ｂにおける導体挟持部７２Ｂの導体挿嵌溝７４Ｂに挿嵌した際に、導体挟持部７２Ａ，７２Ｂと低融点導体３０との接触を接触回避溝７３Ａ，７３Ｂにて回避させる。融点の異なる高融点導体２０と低融点導体３０を、該導体２０，３０の融点に応じた温度で略同時に溶融させて、複合導体線１２Ａ同士を、接続許容部４０における同一種類の高融点導体２０同士と低融点導体３０同士を互いに突き合わせたまま、確実な導電性が確保される良好な状態に接続する。【選択図】図２
