Press-fit terminal

摘要

A press-fit terminal (10) includes through-hole contact portions (30) provided at intermediate portions (66) in a terminal protruding direction, both ends of the through-hole contact portions in a widthwise direction being pressed against an inner peripheral surface of a through-hole (42) of a substrate (40); distal end side wide portions (32) and proximal end side wide portions (34) provided on both sides of the through-hole contact portions in the terminal protruding direction, and protruding toward both sides in the widthwise direction so as to position the substrate in a manner such that the substrate is sandwiched between the distal end side wide portions and the proximal end side wide portions on both sides of the substrate in a thickness direction; width varying portions (36) whose width between both ends in the widthwise direction gradually reduces from the distal end side wide portions toward a distal end side in the terminal protruding direction; a longitudinal perforated hole (24) provided to extend over the width varying portions, the distal end side wide portions, the through-hole contact portions, and the proximal end side wide portions; and a distal end connecting portion (26, 64) integrally connecting the width varying portions separated by the perforated hole, at a distal end side in the terminal protruding direction, wherein when the press-fit terminal is inserted into the through-hole from a side of the distal end connecting portion and portions in the width varying portions are engaged with the through-hole, the press-fit terminal is elastically deformed inward in the widthwise direction due to the perforated hole, and when the distal end side wide portions are passed through the through-hole and the press-fit terminal is elastically returned outward in the widthwise direction, the through-hole contact portions are pressed against the inner peripheral surface of the through-hole to be electrically connected to the inner peripheral surface of the through-hole, and the press-fit terminal being characterized in that the distal end connecting portion has a fragile breaking portion, and when the width varying portions are engaged with the through-hole to be elastically deformed while the width varying portions are passed through the through-hole, the braking portion is broken before the distal end side wide portions reach the through-hole.
