Abstract
An object of the invention is to quickly supply inexpensive large current terminals without entailing complicated metal-working process and labor. Further, another object thereof is to provide methods of metal-working such terminals. A large current male terminal is constructed by forming a hollow cylindrical electric contact part on one end of a conductive pipe, a hollow cylindrical wire crimping part on the other end thereof, and a collar between the electric contact part and the wire crimping part. The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto. The collar has a diameter larger than the other parts
