Verfahren zum Verbinden von elektrischen Drähten

摘要

There is disclosed an electric wire joining method wherein, for connecting a crimp terminal (10) to electric wires (11, 12), invading projections (10b, 10c) of the crimp terminal (10) break through insulative coating portions (11a, 12a) of the electric wires (11, 12) into contact with core wire portions (11b, 12b) of the electric wires (11, 12), and the invading projections (10b, 10c) are ultrasonically welded to the core wire portions (11b, 12b) of the electric wires. The electric wire joining method necessitates no stripping process of the insulative coating portions (11a, 12a) from the electric wires (11, 12) but provides stable electrical connection.
