Abstract:
1. A press-fit terminal press-fitted in a direction of a terminal axis into a through-hole provided on a wiring board, the press-fit terminal comprising: a body part having a smallest cross section; a pressure retaining part; an introducing part having a smallest cross section; and a forward end part having a smallest cross section, the body part, the pressure retaining part, the introducing part, and the forward end part being formed into an integrated body, wherein the smallest cross section of the body part is larger than the smallest cross section of the introducing part and the smallest cross section the forward end, wherein an elongated aperture extending in the terminal axis is formed at a center of the pressure retaining part, a portion of the introducing part, and a portion of the body part, wherein a cross section not including the aperture of the pressure retaining part is larger than a cross section not including the aperture of the introducing part, wherein said pressure retaining part is configured to exert a first elastic force for holding the press-fit terminal when the press-fit terminal is press-fitted into the through-hole, and wherein said introducing part is configured to exert a second elastic force having a second intensity lower than a first intensity of the first elastic force, when said press-fit terminal is being pressed into the through-hole.
