Abstract
Connecting metal fittings for resistance welder comprise receiver metal fittings connected to transformer side and clamping metal fittings connected to a resistance welding gun side. The receiver metal fittings include terminal strips and power supply connecting plates, both provided on the transformer side and fixed thereon, and a pair of rotatable clamping handles having stopping cylinders and stopping pins both provided on a handle lever. The second metal fittings include a shaft lever penetrating the terminal strips on the welding gun side and being inserted into notched grooves formed in tips of the power supply connecting plates, spring sockets being slidably inserted into both ends of the shaft lever, plate springs disposed between the spring sockets and power supply connecting plates, and a cam having stopping levers composed of stopping hooks formed on the tips thereof, and fixed thereon and adapted to make contact with the spring sockets. Clamping between both the metal fittings and clamping between the terminal plates and the power supply connecting plates can be simultaneously accomplished by the pair of handles.
