Abstract

PURPOSE:To automatically manufacture a relay terminal, where a spring portion and a leg portion are integrally constituted, at a small size and enhance stability and reliability of a welded portion by using a complex band member, where the spring portion and the leg portion are integrally constituted. CONSTITUTION:A spring portion 10 formed of a band member made of a Cu alloy such as BeCu and phosphor bronze and a leg portion 11 formed of a band member made of Cu or a Cu alloy are welded to each other in a welded portion 12 at the side edges thereof in the longitudinal direction by the use of an electron beam or laser, thus obtaining a complex band member 13. In the case where the band member 13 is used as a terminal material for a relay, the portions 10, 11 can be automatically fed because of the integral constitution, thereby manufacturing a spring terminal automatically by punching and bending. Consequently, it is possible to enhance productivity, and miniaturize the spring terminal owing to automation of manufacture. Furthermore, stability and reliability of the welded portion 12 can be improved since the portions 10, 11 are previously welded to each other by the use of the electron beam or laser.

The spring part 1 is punched out from the base and processed to form Cu or other C
Since the foot portion 2 was press-pressed from the u-alloy strip material 6 and processed, and the spring portion 1 and the foot portion 2 were spot-welded one by one, the number of processes was large and the productivity was poor. In addition, since the relay terminals 4 could not be downsized in production, and the spot welding was performed one by one, the stability and reliability of the welded portion 3 were low.
