Abstract

Abstract Translated from Japanese 【課題】端子金具の小型化及び多極化とコネクタの低挿入力化が図られても、相手側の導体と確実に電気的に接続できるコネクタを提供する。 【解決手段】コネクタ１にはＦＰＣ４を支持したホルダ２が嵌合する。コネクタ１は雌ハウジング３と端子金具１４を備えている。雌ハウジング３は端子金具１４を収容する。端子金具１４は一対の接触片２０ａ，２０ｂを備えている。一対の接触片２０ａ，２０ｂ間にはホルダ２などが侵入する。温度変化をΔＴとしホルダ２などの線膨張係数をβａとし、接点Ｓと第１の固定箇所Ｃとの距離をｌａとする。端子金具１４などの線膨張係数をβｂとし、接点Ｓと第２の固定箇所Ｄとの距離をｌｂとする。接触片２０ｂの弾性係数をｋとしＦＰＣ４の導体５と端子金具１４との静止摩擦係数をμとし接触片２０ｂの弾性復元力をＦとするとΔＴ×βａ×ｌａ−ΔＴ×βｂ×ｌｂ≦２×（μ×Ｆ／ｋ）を満たしている。 【選択図】 図５ An object of the present invention is to provide a connector which can be reliably and electrically connected to a mating conductor even if the size and the number of poles of the terminal fittings are reduced and the insertion force of the connector is reduced. A holder (2) supporting an FPC (4) is fitted to a connector (1). The connector 1 has a female housing 3 and terminal fittings 14. The female housing 3 houses the terminal fitting 14. The terminal fitting 14 includes a pair of contact pieces 20a and 20b. The holder 2 and the like enter between the pair of contact pieces 20a and 20b. The temperature change is ΔT, the coefficient of linear expansion of the holder 2 and the like is βa, and the distance between the contact point S and the first fixing point C is la. The linear expansion coefficient of the terminal fitting 14 and the like is βb, and the distance between the contact point S and the second fixing point D is lb. Assuming that the elastic coefficient of the contact piece 20b is k, the coefficient of static friction between the conductor 5 of the FPC 4 and the terminal fitting 14 is μ, and the elastic restoring force of the contact piece 20b is F, ΔT × βa × la−ΔT × βb × lb ≦ 2 × (Μ × F / k).
