JUNCTION STRUCTURE FOR ELECTRIC WIRES

摘要

PROBLEM TO BE SOLVED: To enhance the bonding strength between core wires without requiring a complicated work in the case that a copper core wire and an aluminum core wire are bonded with each other by welding.SOLUTION: A junction structure 1 for electric wires comprises a junction part 4 between a copper core wire 21 in a copper electric wire 2 and an aluminum core wire 31 in an aluminum electric wire 3. At a terminal end part of the copper core wire 21, a molded part 23 molded in such a shape that forms a groove 23a into which the aluminum core wire 31 is fitted, is provided. In addition, the junction part 4 is a part where the molded part 23 of the copper core wire 21 and a terminal end part of the aluminum core wire 31 fitted into the groove 23a of the molded part 23 are welded.
