METHOD OF MANUFACTURING TERMINAL, TERMINAL MATERIAL, TERMINAL OBTAINED USING TERMINAL MATERIAL, METHOD OF MANUFACTURING TERMINAL CONNECTION STRUCTURE OF WIRE AND TERMINAL CONNECTION STRUCTURE OF WIRE, AND COPPER OR COPPER ALLOY PLATE MATERIAL FOR TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a terminal exhibiting excellent welding efficiency of laser welding, and to provide a terminal material, a terminal obtained by using the terminal material, a method of manufacturing the terminal connection structure of a wire and the terminal connection structure of a wire, and a copper or a copper alloy plate material for terminal.;SOLUTION: A method of manufacturing a terminal having a tube body caulking portion being crimped to a wire includes a step for preparing a terminal material composed of a copper or a copper alloy base terminal and including a tube development part for forming the tube body caulking portion by being bent, a step for forming a tin layer or a tin alloy layer having a large number of recesses in the surface, as the outermost layer, on the tube development part so that the bottom of the recess remains in the tin layer or tin alloy layer, a step for shaping into a tube body by bending and butting the tube development part, and a step for forming the tube body caulking portion by joining the butting part by laser welding of near-infrared laser light irradiation. The steps are carried out in this order.;COPYRIGHT: (C)2014,JPO&INPIT
