Electrical connector for PC card

Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 ＰＣカードの取出し時に一時的にイジェクタ が突出し、常時突出していることのないＰＣカード用電 気コネクタを提供することを目的とする。 【構成】 イジェクタ２０とイジェクトバー５との間に 配された中間バー１０と、操作開孔の壁面に形成された 第一及び第二カム部Ｉ，IIとを備え、第一カムＩ部は、 ＰＣカード１の挿入時に押釦部２１を前進したロック位 置に弾性条部材２８を保持し、押釦部２１の第一押圧に より上記ロックを解除し、カード抜出時の押釦部２１の 第二押圧によって弾性条部材２８を最前進位置に案内し た後にロック位置へ戻すような循環カム溝５８を有し、 第二カム部IIは、カード挿入時及び第一押圧時に中間バ ー１０の被圧部１４をイジェクタ２０の段部空間に収 め、第二押圧時に被圧部１４をイジェクタの腕状部２２ の前端と当接可能な位置にもたらすように被案内軸部１ ３を案内する循環カム溝を有する。 (57) [Abstract] [Purpose] An object of the present invention is to provide an electrical connector for a PC card in which the ejector temporarily protrudes when the PC card is taken out, and does not always protrude. [Structure] An intermediate bar 10 arranged between an ejector 20 and an eject bar 5 and first and second cam portions I and II formed on a wall surface of an operation opening are provided. , When the PC card 1 is inserted, the elastic strip member 28 is held at the lock position where the push button portion 21 is moved forward, and the lock is released by the first pressing of the push button portion 21, and by the second pushing of the push button portion 21 when the card is removed. And a circulation cam groove 58 for returning the elastic strip member 28 to the lock position after guiding it to the most advanced position, The second cam portion II accommodates the pressed portion 14 of the intermediate bar 10 in the stepped space of the ejector 20 when the card is inserted and when the first pressing is performed, and the pressed portion 14 is held at the second pressing time by the arm-shaped portion 22 of the ejector. Guided shaft part 1 so as to bring it to a position where it can contact the front end of It has a circulating cam groove for guiding 3.
