PRESS-FIT TERMINAL

PROBLEM TO BE SOLVED: To provide a press-fit terminal capable of enhancing a holding force with a substrate of an elastic part and improving reliability in electrical connection while suppressing an increase in a press-fit load.SOLUTION: A press-fit terminal 20 is disposed so as to be opposite to each other via a space C and includes a pair of elastic parts 25 which are interposed between the end of a tip 23 side of a base end 21 and the end of the base end 21 of the tip 23. Moreover, the elastic part 25 includes: a press-fit part 25a which is pressed-fit into a through-hole 14; a base end side coupling part 25b which couples the press-fit part 25a with the base end 21; and a tip side coupling part 25c which couples the press-fit part 25a with the tip 23. In the base end side coupling part 25b, a recess 26 is formed whose hardness is increased by plastic working.SELECTED DRAWING: Figure 3 【課題】圧入荷重の増大を抑制しつつ、弾性部の基板との保持力を高めると共に、電気的接続の信頼性を向上させることが可能なプレスフィット端子を提供する。【解決手段】プレスフィット端子２０は、隙間Ｃを介して互いに対向するように配置され、基端部２１の先端部２３側の端部と、先端部２３の基端部２１側の端部と、の間に介在する一対の弾性部２５と、を備えている。また、弾性部２５は、スルーホール１４に圧入される圧入部２５ａと、圧入部２５ａを基端部２１に連結する基端側連結部２５ｂと、圧入部２５ａを先端部２３に連結する先端側連結部２５ｃと、を備え、基端側連結部２５ｂは、塑性加工によって硬度が高められた凹部２６が形成される。【選択図】図３
