Description

【0001】
【発明の属する技術分野】
本発明はカード用コネクタ装置に係わり、特にパーソナルコンピュータ等の記憶媒体に用いられるICカードや、デジタルカメラ等の電子機器に使用されるカード等に書き込み、または読み出し可能なカード用コネクタ装置に関する。
【0002】
【従来の技術】
パーソナルコンピュータ(以後PCと称する)等の装置の増設記録装置としてICカードに必要な情報を書き込み、あるいは読み出しを行うためにカード用コネクタ装置が一般的に用いられている。
このような従来のカード用コネクタ装置としては、図12に示すように、ハウジング21が配設され、このハウジング21の図示左側には、カード部材(図示せず)が挿入されるカード挿入口22が形成されている。
また、ハウジング21の内側両側面にはカード部材の挿脱を案内するガイドレール23が形成されている。
また、ハウジング21の図示右側には、イジェクト部材24がカード挿脱方向にスライド自在に配設されている。
【0003】
また、ハウジング21の底壁21aには、複数の端子部材25が並列されて配設されている。この端子部材25は、PC側のプリント基板(図示せず)に半田付け可能な端子部25aが、図示左側のカード挿入口22方向に延出形成され、図止右側にカード部材の複数の接触部が接触可能な接点部25aが形成されている。
また、ハウジング21の内側の側壁部には、第1検出スイッチを構成する第1接触バネ片26と第2の接触バネ片27とが互いに接離可能に配設されている。これら第1検出スイッチは、第1、第2接触バネ片26、27が接離することによりカード部材への情報の書き込み可否を検出可能になっている。
また、第1、第2接触バネ片26、27には、ハウジング21の後方側に延出する端子部26a、27aがそれぞれ形成され、更に第1接触バネ片26の端子部26a近傍には、バネ片部26bが切り起こし形成されている。
【0004】
また、カード部材の前端部が突き当たるカード突き当て壁28には、スイッチ収納部29が形成され、このスイッチ収納部29に第2検出スイッチを構成する折り返し型の第3の接触バネ片30が配設されている。
前記第2検出スイッチの第3の接触バネ片30は、ハウジング21の後方側に延出する第3の端子部30aが、第1、第2端子部26a、27aと同方向に延出されて並列配置されている。
また、第3の接触バネ片30には、第1接触バネ片26のバネ片部26bに接触可能な当接部30bが形成されている。
そして、従来のカード用コネクタ装置をPC側のプリント基板に取り付けるには、端子部材のそれぞれの端子部25aおよび第1、第2、第3の端子部26a、27a、30aをプリント基板の配線パターンに位置決めして、半田付けすることにより取り付け可能になっている。
【0005】
このような従来のカード用コネクタ装置は、カード挿入口22からカード部材(図示せず)をガイドレール23に沿って挿入すると、カード部材の前端部が第3の接触バネ片30を押圧して、当接部30bが第1バネ片26のバネ辺部26bに接触する。このことにより、カード部材の装着が行われたことを検出することができる。
また、この時、挿入されたカード部材のライトプロテクト用識別子が、情報の書き込み禁止位置に操作されている場合は、第1、第2接触バネ片26、27が接触せず、これによってカード部材に情報の書き込み禁止がされて、書き込みが行えないようになっている。
【0006】
また、ライトプロテクト用識別子が、情報の書き込み可能位置に操作されている場合は、第1接触バネ片26がライトプロテクト用識別子に押圧されて第2接触バネ片27に接触することにより、第1スイッチ回路が切り換わってカード部材に情報の書き込みを行うことができるようになっている。

【発明が解決しようとする課題】
しかし、上述したような従来のカード用コネクタ装置の第1、第2検出スイッチのそれぞれの第1、第2、第3の接触バネ片26、27、30には、半田付け部である端子部26a、27a、30aが形成され、この端子部26a、27a、30aを、それぞれプリント基板に半田付けしなければならなかったので組立に時間が掛かった。
また、半田付け時に加わる高温でハウジング21が変形したりするのを防止するために、半田付け温度あるいは半田付け時間等を細かく管理しなければならず煩わしかった。
本発明は前述したような問題点に鑑みてなされたもので、挿入されたカード部材を検出するための検出スイッチ、および情報の書き込み禁止を検出するための検出スイッチを備えたものにおいて、それぞれの検出スイッチの半田付け作業を不要としたカード用コネクタ装置を提供することを目的とする。

【0015】

【0028】
前記ロック部材7は、図11に示すように、ハウジング2を裏面側から見た状態において、第1係止部7hがハウジング2の係合部2fにスナップ係合して、ハウジング2に係合支持されている。
また、一対の係支腕7g、7gには、図3に示すように、上方に突出する鈎状の第2係止部7kが形成され、この第2係支部7kは、図11に示すハウジング2の裏面側に係合支持可能になっている。

前記カード当接部8fは、スイッチ収納部2kを構成する内側の側壁2jの一部が切り欠きされて、カード挿入部3側に突出している。そして、内側の側壁2jから突出するカード当接部8fに、カード収納部3に挿入したカード部材(図示せず)の先端部側のコーナ部が当接することにより、第1腕部8eが弾性変形して、第1可動接点部8bが後述する第1固定接点部材10側に弾性変形可能するようになっている。
【0031】
また、可動接点部材8の基材8aは、図9に示すように、第1可動接点部8bの手前側で第1腕部8eより上方に位置する部分が、手前側に延びる細長状の第2スリット溝8gにより切り離されて、片持ち針状の第2腕部8hが形成され、この第2腕部8hの奥側の先端部に第2可動接点部8cが形成されている。
そして、第2腕部8hは、奥側先端部の第2可動接点部8cより手前側に、三角形状に形成されたW/P(ライトプロテクト)検出部8jが、カード挿入部3側に突出している。

即ち、可動接点部材8は、長尺状の1枚の金属板の一部を打ち抜いて、第1、第2可動接点部8b、8cを、長手方向の前後に並列させて形成している。
【0033】
また、可動接点部材8は、図8に示すように、第1、第2可動接点部8b、8cを形成した基材8aの奥側を折り曲げて位置決め部8kを形成し、この位置決め部8kがハウジング2の端子位置決め部2dに位置決め可能となっていると共に、位置決め部8kから端子部材4の基部4dと同方向に延出させて固定部8mが形成され、この固定部8mの図示右側端部に、端子部材4の治具接触部4eと同様に治具接触部8nが形成されている。

前記第1固定接点部材10は、一方側に形成した基材10aがスイッチ収納部2k内に位置して、可動接点部材8の基材8aと平行に形成されている。この基材10aは、スイッチ収納部2kの奥側から第1可動接点部8bと対向する部分まで延びて形成され、先端部の第1可動接点部8bと対向する部分に第1固定接点部10bが形成されている。
【0036】
前記第1固定接点部材10の基材10aは、図8に示すように、ハウジング2に形成した支持部2nに支持されて、動きが規制されている。また、固定接点部材10の基材10aの奥側をL字状に折り曲げて、ハウジング2の端子位置決め部2dに位置決め可能な位置決め部10cを形成すると共に、位置決め部10cを可動接点部材8のFPC固定部9と同方向に折り曲げてFPC固定部10dが形成されている。

【0038】
また、第1固定接点部材10の外側には、長尺状の第2固定接点部材11が配設されており、この第2固定接点部材11は、一方側に形成した基材11aがスイッチ収納部2k内に位置して、可動接点部材8の基材8aと平行状態で取り付けられている。また、第2の固定接点部材11は、可動接点部材8の第2腕部8hと対向する部分が傾斜状に切り起こしされて、弾性変形可能な腕部11bが形成され、この腕部11bの先端部側で、可動接点部8cと対向する部分に第2固定接点部11cが形成されている。
【0039】
前記腕部11bの第2固定接点部11cは、第2可動接点部8cが接触して押圧されると、外側の側壁2h側に弾性変形するようになっている。
そして、腕部11bが弾性変形すると、互いに接触する第2可動接点部8cと第2固定接点部11cとが摺動して、接点部のクリーニングを行うことができ、第2固定接点部11cと第2可動接点部8cとの導通を、常に確実に行うことができるようになっている。
【0040】
また、第2固定接点部材11は、基材11aの奥側を折り曲げて位置決め部11dを形成し、この位置決め部11dを第1固定部材10の固定部10fと同方向に延長させて固定部11eを形成し、この固定部11eの図示右側端部に、治具接触部11fが形成されている。
