| 发明名称 | Terminal, a wire connecting structure and a method of manufacturing the terminal | ||
| 摘要 | A terminal includes a connector portion, a tubular crimp portion that crimps/joins with a wire, and a transition portion joining the two portions. The tubular crimp portion is composed of a metal member including a base material of copper or copper alloy with 0.20-1.40 mm thickness and a coating layer of tin, tin alloy, nickel, nickel alloy, silver or silver alloy with 0.2-3.0 μm thickness formed on the base material. The tubular crimp portion has a weld portion formed by butt-welding and having, in its cross-section perpendicular to a terminal longitudinal direction, a phase existing therein of tin, tin alloy, nickel, nickel alloy, silver or silver alloy greater than 0.01 μm2. The tubular crimp portion is a closed tubular body with one end opposite to a wire-insertion-opening being closed. | ||

| 主权项 | 1. A terminal comprising: a connector portion adapted to mate with another terminal; a tubular crimp portion adapted to crimp and join with an electric wire; and a transition portion joining the connector portion and the tubular crimp portion, the tubular crimp portion being composed of a metal member including a base material and a coating layer formed on the base material, the base material being composed of one of copper and a copper alloy and having a thickness in a range of 0.20 mm to 1.40 mm, the coating layer being composed of one of tin, a tin alloy, nickel, a nickel alloy, silver and a silver alloy and having a thickness in a range of 0.2 μm to 3.0 μm, the tubular crimp portion having a weld portion formed by butt welding the metal member, the weld portion having, in a cross section of the weld portion perpendicular to a longitudinal direction of the terminal, a phase existing therein of one of tin, a tin alloy, nickel, a nickel alloy, silver and a silver alloy, the phase being of a size greater than 0.01 μm2, the tubular crimp portion being formed into a closed tubular body in which one end opposite to an electric wire insertion opening is closed. | ||
