Method of manufacturing a wiring material

摘要

A wiring material is provided by electrically connecting a connecting terminal with two single line conductors arranged in parallel. The connecting terminal is provided with a tube-shaped section for storing two single line conductors, the two single line conductors are inserted into the tube-shaped section, resistance welding is performed by carrying electricity from the external of the tube-shaped section in a status where the tube-shaped section and the single line conductors are mutually brought into contact, and the connecting terminal is electrically connected with the two single line conductors.

1. A method of manufacturing a wiring material having a connecting terminal electrically connected to a circular shaped single line conductor, comprising the steps of:
bending a single line conductor to have a circular shape; extending both ends of the single line conductor that is bent in parallel; forming a tube-shaped section having a circular cross section at the connecting terminal for accommodating the both ends of the single line conductor; inserting the both ends of the single line conductor into the tube-shaped section; and conducting a resistance welding by energizing welding electrodes from the outer periphery of the tube-shaped section, in a state where a portion of the tube-shaped section between the ends of the single line conductor is pushed by the welding electrode into a space formed between the ends of the single line conductor and an inner periphery surface of the tube-shaped section contacts with the both ends of the single line conductor to electrically connect the connecting terminal with the both ends of the single line conductor.
