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メモリーカード等のカード部材に書き込み、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）等の情報機器の増設記録装置として、内部にＩＣ（集積回路）を埋設したカード部材に、種々の情報の書き込み、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には、ハウジング内部にカード部材を装着可能なカード装着部が形成されており、ハウジング内部には、カード装着部に装着したカード部材を排出するための排出機構が設けられている。
この排出機構には、カード装着状態におけるカード部材をロックして動きを規制可能なスライダーが配設され、このスライダーは、コイルバネでカード排出方向に常に付勢されている。
【０００３】
また、排出機構により、ロックを解除したスライダーが、コイルバネの付勢力で排出方向にスライドすることにより、カード装着部に装着したカード部材が排出可能になっている。
このような従来のカード用コネクタ装置は、カード装着部に装着したカード部材を抜け止めするために、カード部材の側縁部に凹部を形成し、この凹部に弾性係合可能な係合部材をスライダーに取り付けていた。
【０００４】
そして、カード装着状態におけるカード部材は、凹部にスライダー側の係合部材が弾性係合してカード装着部から抜け止めされると共に、カード排出時においても、凹部に係合部材が弾性係合した状態で、カード装着部から所定量排出した排出状態となる。この所定量排出状態のカード部材を、操作者が手作業で引き抜くことにより、凹部から係合部材が外れて、カード部材を取り出すことができる。
そのために、従来のカード用コネクタ装置は、凹部と、この凹部に弾性係合可能な係合部材とにより、カード排出時のカード部材がハウジング外部に飛び出すのを防止できる。
【０００５】
【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は、凹部に弾性係合する係合部材の取付位置がばらついて、凹部との係合力が大きくなると、手作業でカード引き抜き時に、カード部材の凹部に集中加重が加わり、繰り返しの着脱動作で、カード部材が破損するおそれがあった。
【０００６】
また、係合部材の取付位置のバラツキで、凹部との係合力が小さくなると、カード排出時のカード部材がハウジング外部に飛び出して、破損するおそれがあった。
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、カード装着部から排出する時のカード部材の飛び出しを確実に防止すると共に、排出時に凹部に加わる集中加重を小さくしてカード部材を損傷なく引き抜くことができるカード用コネクタ装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記課題を解決するための第１の解決手段として本発明のカード用コネクタ装置は、一方の面に複数の接触部を形成したカード部材を装着可能なカード装着部を内部に形成したハウジングと、前記カード部材の前記複数の接触部と接触可能な前記カード装着部に配設した複数の端子部材と、前記カード装着部に装着した前記カード部材を排出可能な排出機構とを備え、前記カード装着部を形成した部分の前記ハウジングの底壁には、前記カード部材の下面に弾接可能な弾性押圧部を形成し、前記ハウジングを取付可能なプリント基板に取り付けたとき、前記弾性押圧部と前記プリント基板との間に所定の隙間を形成することにより前記弾性押圧部を弾接可能としたことを特徴とする。
【０００９】
また、上記課題を解決するための第２の解決手段として、前記排出機構は、前記カード部材の装着または排出に連動して同方向にスライド移動可能なスライド部材と、このスライド部材を排出方向に付勢する付勢部材と、この付勢部材の付勢力に抗して前記スライド部材の動きを規制可能なカム機構とを有し、前記カード装着部に前記カード部材を装着したカード装着状態における前記スライド部材は、前記カム機構によりロックされて動きが規制され、前記スライド部材がロック状態において、前記付勢部材の付勢力に抗して前記装着方向に前記スライド部材を一旦押圧することにより、前記ロックが解除されて、前記スライド部材を介して前記カード装着状態の前記カード部材を前記カード装着部から排出するようにしたことを特徴とする。
【００１０】
また、上記課題を解決するための第３の解決手段として、前記カム機構は、ハート型のカム溝と、前記スライド部材に一端部が支持され他端部が前記カム溝に沿って摺動可能な摺動部材とを有し、前記カード装着状態における前記スライド部材は、前記カム溝に形成したロック部に前記摺動部材が位置して前記ロックされ、このロック状態において、前記カード部材を前記カード装着方向に押圧することにより前記ロックが解除されるようにしたことを特徴とする。
【００１１】
また、上記課題を解決するための第４の解決手段として、前記カード装着部に装着した前記カード部材の前端部寄りの下面と対向する部分の前記ハウジングの前記底壁をくり抜いて開口部を形成し、前記弾性押圧部は、前記カード装着部の入り口部と前記開口部とに挟まれた部分の前記底壁上に形成したことを特徴とする。
【００１２】
また、上記課題を解決するための第５の解決手段として、前記弾性押圧部は、前記底壁上で前記カード部材に向かうように突出形成したことを特徴とする。
【００１３】
また、上記課題を解決するための第６の解決手段として、前記カード装着部の上方を覆うカバー部材を配設し、このカバー部材には、前記ハウジングの幅方向を挟み込む左右側板を有し、この左右側板には、前記プリント基板に実装可能な取付部を形成し、この取付部を前記ハウジングの前記底壁から所定寸法突出させて、前記所定の隙間を形成したことを特徴とする。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態のカード用コネクタ装置を図１〜図１４に基づいて説明する。図１は本発明に関するカード用コネクタ装置の上面図であり、図２は図１の側面図であり、図３は図１の正面図であり、図４は図１の４−４断面図であり、図５は本発明に係わるハウジングを説明する上面図であり、図６は図５の正面図であり、図７〜図１１は本発明に係わるカード部材の着脱動作を説明する面であり、図１２は本発明に係わるカード部材の装着状態を説明する要部断面であり、図１３〜図１５は本発明に係わるカード部材を示す図面である。
【００１５】
まず、本発明の実施の形態のカード用コネクタ装置１は、樹脂材料等の絶縁材で形成されたハウジング２を有し、このハウジング２は、図５に示すように、外径が略矩形状に形成されている。
また、ハウジング２は、表面側が凹み形成されて底面が平坦状の底壁２ａと、この底壁２ａの図示左側に形成した奥側壁２ｂと、この奥側壁２ｂの図示上端部につながって右側壁２ｃと、この右側壁２ｃと対向する側に奥測壁２ｂの図示下端部につながって左端壁２ｄとで３方が囲まれて形成されている。
【００１６】
また、左側壁２ｄの内側には、所定の幅寸法のバネ保持溝２ｅを挟んでガイド壁２ｆが左側壁２ｄと平行に同じ高さで形成されている。
そして、奥側壁２ｂと右側壁２ｃとガイド壁２ｆとに囲まれた底壁２ａ上に、後述するカード部材１２を装着可能な後述するカード装着部１０が形成されている。また、底壁２ａの中央部を矩形状にくり抜いて開口部２ｇが形成され、この開口部２ｇの図示右側には、右側壁２ｃ及び左側壁２ｄ間を橋渡しする底壁２ａからなる桟部２ｈが形成されている。
この桟部２ｈは、カード装着部１０の入り口部である図示右側に凹部２ｊが形成され、この凹部２ｊによって幅狭になっている。そのために、桟部２ｈは容易に弾性変形可能になっている。
また、左右の側壁２ｃ、２ｄには、複数のスナップ突起２ｍが突出形成され、このスナップ突起２ｍに後述するカバー部材９がスナップ係合可能になっている。
【００１７】
また、桟部２ｈには、後述するカード部材１２に向かって突出して弾性押圧部３が一体形成されている。即ち、後述するカード装着部１０の入り口部近傍の底壁２ａに弾性押圧部３が形成されている。
また、奥側壁２ｂには複数の弾性を有する金属板等で形成した複数の端子部材４が略等間隔に並列して埋設されている。前記端子部材４は、奥側壁２ｂの外部に略等間隔に延出する端子部４ａが形成され、この端子部４ａは、後述するプリント基板に半田付け等により実装可能になっている。
また、端子部材４は、奥側壁２ｂの内部のカード装着部１０側に延出する接点部４ｂが底壁２ａ上に位置して片持ち梁状になっており、前記接点部４ｂに後述するカード部材１２の接触部１２ｅが弾接可能になっている。
【００１８】
また、図５に示すバネ保持溝２ｅには、引っ張りコイルバネからなる付勢部材５が配設され、この付勢部材５は、一端部５ａがバネ保持溝２ｅの底壁２ａに突出形成したバネ支持突起２ｋに支持され、他端部５ｂがスライド部材６のバネ係支部６ｄに係支されている。
そのために、スライド部材６は、付勢部材５の付勢力で常に後述するカード部材１２の排出方向に付勢されて、図５に示すように、カード部材１２が未装着状態の初期位置においては、左側壁２ｄとガイド壁２ｆとに形成したストッパー部２ｎ、２ｎにスライド部材６が当接した状態になっている。
前記スライド部材６は、後述するカード部材１２の前端部１２ａが当接可能な当接部６ａがカード装着部１０側に突出形成され、ガイド壁２ｆより若干カード装着部１０側に突出する略くの字状の弾性変形可能な係合部６ｂが形成されている。この係合部６ｂの図示下方が略三角形状にくり抜きされて切り欠き部６ｃが形成され、この切り欠き部６ｃに、係合部６ｂが弾性変形可能になっている。
【００１９】
また、スライド部材６には、図示右側に付勢部材５の他端部５ｂを係支可能なバネ係支部６ｄが形成されている。そして、付勢部材５で付勢されたスライド部材６が、ストッパー部２ｎに当接した初期状態における係合部６ｂの下部には、規制壁２ｐが形成され、この規制壁２ｐによって、係合部６ｂの剛性を強くしている。
また、切り欠き部６ｃの図示左側下部のスライド部材６には、支持孔６ｅが形成され、この支持孔６ｅに後述する摺動部材７の一端部７ａが支持されて回動自在になっている。
【００２０】
また、スライド部材６の図示左端部には、略台形状で幅狭の押え部６ｆが形成され、この押え部６ｆが上方側に折り返されて、支持孔６ｅに支持した後述する摺動部材７を弾性付勢して抜け止めしている。
前記摺動部材７は、針金状の１本の棒部材からなり、一端部７ａと他端部７ｂが縦長状の腕部７ｃから同方向に直角状に折り曲げ形成されている。
そして、摺動部材７は、一端部７ａが支持孔６ｅに支持されて、腕部７ｃの上方がスライド部材６の押え部６ｆに弾性付勢され、他端部７ｂがスライド部材６の図示左端部の外側に位置している。
【００２１】
また、図５に示す、スライド部材６と、ハウジング２の後側壁２ｂとの間の底壁２ａ上には、摺動部材７と共にカム機構を構成するハート型のカム溝８が彫り込みされている。そして、押え部６ｆによりカム溝８の底面側に付勢された摺動部材７の他端部７ｂが、カム溝８内の底面上に位置し、カム溝８に沿って摺動可能になっている。
前記カム溝８は、階段状及び傾斜状の底面（図示せず）を組み合わせて形成され、ハート型に形成した部分の２本の溝部８ａ、８ａに挟まれた部分に、略ハート型のロック部８ｂが突出形成されている。このロック部８ｂの前端部に、摺動部材７の他端部７ｂが位置することで、スライド部材６がロックされて動きが規制されるようになっている。
【００２２】
即ち、ハウジング２には、後述するカード装着部１０に装着したカード部材１２を排出可能な排出機構が形成され、この排出機構は、後述するカード部材１２の装着または排出に連動して同方向にスライド移動可能なスライド部材６と、このスライド部材６を排出方向に付勢する付勢部材５と、この付勢部材５の付勢力に抗してスライド部材６をロックして動きを規制可能なカム溝８及び摺動部材７を有するカム機構とからなっている。
【００２３】
また、本発明のカード用コネクタ装置１は、図１〜図３に示すように、ハウジング２の上部を覆う金属板からなるカバー部材９が配設されている。このカバー部材９は、図３に示すように、ハウジング２の上部を覆う平坦状のカード摺接板９ａと、ハウジング２の幅方向を挟み込んで互いに対向する右側板９ｂと左側板９ｃとを有し、この左右の側壁９ｂ、９ｃには、後述するプリント基板に半田付け等で実装可能な舌片状の取付部９ｄが形成されている。
この取付部９ｄのカード摺接板９ａからの寸法は、ハウジング２の高さ寸法より大きく形成されている。
【００２４】
前記カバ−部材９の左右の側板９ｂ、９ｃには、ハウジング２のスナップ突起２ｍがスナップ係合可能な係合孔９ｅが形成され、この係合孔９ｅにスナップ突起２ｍをスナップ係合させて、カバー部材９がハウジング２に取り付けられている。そして、カバー部材９をハウジング２に取り付けると、図３、図４に示すように、ハウジング２の上部がカバー部材９で覆われて、カバー部材９のカード摺接板９ａと底壁２ａとの間に、後述するカード部材１２を装着可能なカード装着部１０が形成される。
【００２５】
また、ハウジング２にスナップ係合させて取り付けたカバー部材９は、取付部９ｄがハウジング２の底壁２ａから下方側に寸法Ａ突出するようになっている。
そのために、カバー部材９を取り付けたハウジング２を、図４の２点鎖線で示すプリント基板１１に載置すると、プリント基板１１とハウジング２の底壁２ａ及び桟部２ｈとの間には寸法Ａの隙間が形成されるようになっている。
この寸法Ａの隙間によって、弾性押圧部３を形成した桟部２ｈがプリント基板１１側に弾性変形可能になっている。
また、カバー部材９を取り付けた状態のハウジング２は、プリント基板１１に載置すると、取付部９ｄをプリント基板１１に実装可能になっている。
【００２６】
前記カード装着部１０には、内部にＩＣ（集積回路）を埋設した、図１３〜図１５に示すようなカード部材１２が装着可能になっている。
このカード部材１２は、図１５に示すように、前端部１２ａの図示左側の一方のコーナ部１２ｂが斜めにカットされている。
また、図１４に示すように、カード部材１２は、互いに対向する下面１２ｃと上面１２ｄとが平坦状に形成され、前端部１２ａ側の下面１２ｃが切り欠きされて段差状に形成され、この段差状の下面１２ｃ側に、内部のＩＣ（図示せず）に導通する複数の接触部１２ｅが露出して整列形成されている。
【００２７】
また、斜めにカットしたコーナ部１２ｂ寄りの一方の側縁部１２ｆには、図１５に示すように、スライド部材６の係合部６ｂが弾性係合可能な凹部１２ｇが形成されている。また、一方の側縁部１２ｆと対向する側に他方の側縁部１２ｈが形成され、この他方の側縁部１２ｈの前端部１２ａ側のコーナ部は円弧状に形成されて、他方のコーナ部１２ｂと非対称形状になっている。
そのために、カード装着部１０へのカード部材１２の逆挿入を防止するようになっている。
【００２８】
また、カード部材１２を、図４に示すカード装着部１０に挿入すると、カード部材１２の下面１２ｃに弾性押圧部３が弾接すると共に、カード部材１２の上面１２ｄがカバー部材９のカード摺接板９ａに摺接するので、カード装着部１０から着脱時のカード部材１２は、従来のものより摩擦抵抗が大きくなるようになっている。
また、カード装着部１０にカード部材１２を装着した時のハウジング２の桟部２ｈは、図１２に示すように、プリント基板１１側に弾性変形するが、プリント基板１１との間には寸法Ａの隙間があるので、桟部２ｈの底面がプリント基板１１に接触しないようになっている。
【００２９】
このような本発明のカード用コネクタ装置１をプリント基板１１に実装した状態で、カード部材１２の着脱動作を説明すると、まず、図５に示すカード挿入前の初期状態においては、スライド部材６が付勢部材５の付勢力でストッパー部２ｎに当接した状態になっている。
この初期状態のカード装着部１０に、図７に示すように、カード部材１２を矢印Ｂの装着方向に挿入するカード装着途中においては、カード部材１２の凹部１２ｇにスライド部材６の係合部６ｂが係合すると共に、前端部１２ａがスライド部材６の当接部６ａを押圧して、付勢部材５の付勢力に抗してスライド部材６がハウジング２の奥側にスライド移動する。
このようなカード挿入途中におけるカム機構は、図７に示すように、カム溝８に位置する摺動部材７の他端部７ｂが、反時計回り方向に回動して、ロック部８ｂの右側の溝部８ａを摺動している。
【００３０】
次に、カード部材１２を完全に押し切ったオーバーストローク状態においては、図８に示すように、カード部材１２は、前端部９ａがハウジング２の奥側壁２ｂにぶつかると共に、摺動部材７がカム溝８の最奥部に位置して、カード部材１２の矢印Ｂの装着方向への動きが停止する。
この時のカム機構は、カード挿入途中と同様に摺動部材７の他端部７ｂが、カム溝８に案内されて反時計回り方向に回動した状態になっている。
そして、オーバーストロークの状態から、カード部材１２に加えていた矢印Ｂの押圧力を解除すると、付勢部材５の付勢力でスライド部材６が初期状態に戻ろうとするが、摺動部材７の他端部７ｂが、カム溝８に案内されてロック部８ｂの前端部に当接して、スライド部材６がロック状態となって動きが規制される。
【００３１】
前記スライド部材６がロック状態となると、カード部材１２の接触部１２ｅが複数の端子部材４の接点部４ｂに接触すると共に、凹部１２ｇにスライド部材６の係合部６ｂが弾性係合してカード部材１２がカード装着部１０に抜け止めされて装着される。
このカード装着状態において、カード部材１２内部のＩＣに書き込み、または読み出しを行うことができる。
【００３２】
次に、カード装着状態におけるカード部材１２を、図１０に示すように、付勢部材５の付勢力に抗して、一旦矢印Ｂのカード装着方向に押圧して、再度オーバストロークとすると、摺動部材７がロック部８ｂから離れて、反時計回り方向に回動する。この状態から、カード部材１２に加えていた矢印Ｂの装着方向への押圧力を解除すると、図１１に示すように、付勢部材５の付勢力で、スライド部材６が矢印Ｃのカード排出方向にスライド移動して初期状態に自動復帰することにより、カード部材１２がカード排出状態となる。
【００３３】
この時の摺動部材７は、図１０に示す状態からロック部８ｂの左側の溝部８ａを案内されて図１１に示す初期状態に自動復帰する。
また、オーバストローク状態のカード部材１２は、スライド部材６の当接部６ａによって前端部１２ａが押されて、矢印Ｃの排出方向に排出され、図１１に示すようなカード排出状態となる。
このカード排出状態となった時のスライド部材６は、付勢部材５の付勢力でストッパー部２ｎに衝突してストップするが、スライド部材６と共に排出方向に移動していたカード部材１２は、慣性力で矢印Ｃ方向に飛び出そうとする力が働く。
【００３４】
けれども、カード部材１２は、凹部１２ｇにスライド部材６の係合部６ｂが弾性係合していると共に、図１２に示すように、下面１２ｃがハウジング２の弾性押圧部３に弾接し、また、上面１２ｄがカバー部材９のカード摺接板９ａに弾接している。そのために、矢印Ｃの排出方向に飛び出そうとする力が加わったカード部材１２にブレーキが掛かり、カード部材１２がハウジング２の外部に飛び出すのを防止できる。
【００３５】
また、図１１に示すように、カード排出状態における、凹部１２ｇに弾性係合している係合部６ｂは、規制壁２ｐ上に位置するようになっている。そのために、慣性力でカード部材１２に矢印Ｃの排出方向に飛び出そうとする力が働いて、図示下方側に弾性変形しょうとする係合部６ｂが、規制壁２ｐに当接して剛性が強くなり、更に確実にカード部材１２の飛び出しを防止できる。
このような本発明のカード用コネクタ装置１は、カード部材１２のプッシュ・プッシュ操作で、カード装着部１０に装着、または排出の両方を行うことができるので、操作性が良い。
【００３６】
本発明の実施の形態の説明では、弾性押圧部３をハウジング２に一体形成したもので説明したが、弾性押圧部３は、スポンジ等の弾性体を桟部２ｈに貼り付けたものでも良い。
また、カード部材１２は、プッシュ・プッシュ操作で、装着、及び排出を行うもので説明したが、スライド部材６を矢印Ｂまたは矢印Ｃ方向にスライド操作可能なイジェクト部材（図示せず）を配設したものでも良い。
また、カバー部材９の左右の側板９ｂ、９ｃに、プリント基板１１に実装可能な取付部９ｄをハウジング２の底壁２ａから所定寸法突出させて寸法Ａの隙間を形成したもので説明したが、ハウジング２の底壁２ａの下面から直接突出する突起を形成して、寸法Ａの隙間を形成したものでもよい。
【００３７】
【発明の効果】
以上説明したように、本発明のカード用コネクタ装置は、カード装着部を形成した部分のハウジングの底壁には、カード部材の下面に弾接可能な弾性押圧部を形成したので、カード部材をカード装着部から排出時に、カード部材の下面と弾性押圧部との摩擦により、カード部材がハウジング外部に飛び出しを防止することができる。そのために、飛び出しによるカード部材の故障を防止できる。
【００３８】
また、ハウジングを取付可能なプリント基板に取り付けたとき、弾性押圧部プリント基板との間に所定の隙間を形成したので、ハウジングの底壁が隙間部分に弾性変形することができ、カード装着部にカード部材をスムーズに挿入して装着することができる。
【００３９】
また、ロック状態におけるスライド部材を付勢部材の付勢力に抗して装着方向に一旦押圧することにより、スライド部材のロックが解除されて、カード装着状態のカード部材がスライド部材を介してカード装着部から排出可能としたので、カード部材をプッシュ・プッシュ操作することで、カード部材の装着、排出ができる操作性の良いカード用コネクタ装置を提供できる。
【００４０】
また、カード装着状態におけるスライド部材は、カム溝に形成したロック部に摺動部材が位置してロックされ、このロック状態において、カード部材をカード装着方向に押圧することによりロックが解除されるようにしたので、イジェクト部材等が無くても、カード部材のプッシュ・プッシュ操作で装着、排出することができ、構造が簡単で部品点数の少ないカード用コネクタ装置を提供できる。
【００４１】
また、カード装着部に装着したカード部材の前端部寄りのカード装着部の底壁をくり抜いて開口部を形成し、弾性押圧部は、カード装着部の入り口部と開口部とに挟まれた部分の底壁上に形成したので、弾性押圧部に適度な弾性力を付勢して、排出時にカード部材が飛び出すのを確実に防止できる。
【００４２】
また、弾性押圧部は、底壁上に位置するカード部材に向かって突出形成したので、ハウジングを成型加工時に弾性押圧部を同時に形成することができる。
【００４３】
また、カバー部材の左右側板には、プリント基板に実装可能な取付部を形成し、この取付部をハウジングの底壁から所定寸法突出させて、底壁とプリント基板との間に隙間を形成したので、カバー部材の左右側壁をハウジングの底壁から突出形成するだけで、プリント基板とハウジングの底壁との間に隙間を形成することができ、組立の容易なカード用コネクタ装置を提供できる。

BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card connector device, and more particularly to a card connector capable of writing to or reading from a card member such as an IC card used for a storage medium such as a personal computer or a memory card used for an electronic device such as a digital camera Relates to the device.
[0002]
[Prior art]
As an additional recording device for information equipment such as a personal computer (hereinafter referred to as PC), a card connector device is generally used to write or read various information on a card member having an IC (integrated circuit) embedded therein. Has been used. In such a conventional card connector device, a card mounting portion in which a card member can be mounted is formed inside the housing, and a discharge mechanism for discharging the card member mounted on the card mounting portion inside the housing. Is provided.
The ejecting mechanism is provided with a slider that can lock the card member in a card-mounted state to restrict movement, and this slider is always urged in the card ejecting direction by a coil spring.
[0003]
Further, the card member mounted on the card mounting portion can be discharged by the slider that has been unlocked by the discharge mechanism sliding in the discharge direction by the biasing force of the coil spring.
In such a conventional card connector device, in order to prevent the card member mounted on the card mounting portion from coming off, a concave portion is formed in the side edge portion of the card member, and an engaging member capable of elastic engagement with the concave portion is provided. It was attached to the slider.
[0004]
The card member in the card mounted state is elastically engaged with the recess by the engaging member on the slider side to prevent the card member from coming off from the card mounting portion, and the engaging member is elastically engaged with the recess even when the card is ejected. In this state, a predetermined amount is discharged from the card mounting portion. By manually pulling out the card member in a predetermined amount discharged state, the engaging member is removed from the recess, and the card member can be taken out.
Therefore, the conventional card connector device can prevent the card member from popping out of the housing when the card is ejected by the recess and the engaging member that can be elastically engaged with the recess.
[0005]
[Problems to be solved by the invention]
However, in the conventional card connector device as described above, when the engaging position of the engaging member that is elastically engaged with the concave portion varies and the engaging force with the concave portion increases, the concave portion of the card member is manually pulled out when the card is pulled out. The card member may be damaged by repeated attaching and detaching operations.
[0006]
Further, if the engaging force with the concave portion is reduced due to variations in the mounting position of the engaging member, the card member when the card is ejected may jump out of the housing and be damaged.

[0027]
Further, as shown in FIG. 15, a recess 12g is formed in one side edge portion 12f near the corner portion 12b cut obliquely so that the engaging portion 6b of the slide member 6 can be elastically engaged. The other side edge portion 12h is formed on the side facing the one side edge portion 12f, and the corner portion on the front end portion 12a side of the other side edge portion 12h is formed in an arc shape, and the other corner portion is formed. It is asymmetrical with 12b.
Therefore, reverse insertion of the card member 12 into the card mounting part 10 is prevented.
[0028]
When the card member 12 is inserted into the card mounting portion 10 shown in FIG. 4, the elastic pressing portion 3 is elastically contacted with the lower surface 12 c of the card member 12, and the upper surface 12 d of the card member 12 is the card sliding contact plate of the cover member 9. Since it is in sliding contact with 9a, the card member 12 at the time of attachment / detachment from the card mounting portion 10 has a higher frictional resistance than the conventional one.
Further, the crosspiece 2h of the housing 2 when the card member 12 is mounted on the card mounting portion 10 is elastically deformed toward the printed circuit board 11 as shown in FIG. Therefore, the bottom surface of the crosspiece 2h is prevented from contacting the printed circuit board 11.
[0029]
In the state where the card connector device 1 according to the present invention is mounted on the printed board 11, the attaching / detaching operation of the card member 12 will be described. First, in the initial state before the card insertion shown in FIG. The urging force of the urging member 5 is in contact with the stopper portion 2n.
As shown in FIG. 7, the card member 12 is inserted in the mounting direction indicated by the arrow B into the card mounting portion 10 in the initial state, and the engaging portion 6 b of the slide member 6 is inserted into the recess 12 g of the card member 12. And the front end portion 12 a presses the contact portion 6 a of the slide member 6, and the slide member 6 slides to the back side of the housing 2 against the urging force of the urging member 5.
The cam mechanism in such a card insertion midway, as shown in FIG. 7, the other end portion 7b of the slide member 7 located in the cam groove 8, rotates in the counterclockwise direction, the right side of the locking portion 8b The groove portion 8a is slid.
[0030]
Next, in the overstroke state in which the card member 12 is completely pushed out, as shown in FIG. 8, the card member 12 has the front end portion 9a hitting the back side wall 2b of the housing 2, and the sliding member 7 is in the cam groove. 8, the movement of the card member 12 in the mounting direction of the arrow B stops.
The cam mechanism at this time, the other end portion 7b of the slide member 7 like the way the card insertion, in a state of being rotated is guided by the cam groove 8 in the counterclockwise direction.
When the pressing force of the arrow B applied to the card member 12 is released from the overstroke state, the slide member 6 tries to return to the initial state by the biasing force of the biasing member 5. The end portion 7b is guided by the cam groove 8 and comes into contact with the front end portion of the lock portion 8b, so that the slide member 6 is locked and the movement is restricted.
[0031]
When the slide member 6 is in a locked state, the contact portion 12e of the card member 12 contacts the contact portions 4b of the plurality of terminal members 4, and the engagement portion 6b of the slide member 6 elastically engages the recess 12g. The member 12 is mounted on the card mounting unit 10 while being prevented from coming off.
In this card mounted state, writing to or reading from the IC inside the card member 12 can be performed.
[0032]
Next, when the card member 12 in the card mounted state is pressed once in the card mounting direction indicated by the arrow B against the biasing force of the biasing member 5 as shown in FIG. The moving member 7 moves away from the lock portion 8b and rotates counterclockwise. When the pressing force in the mounting direction of the arrow B applied to the card member 12 is released from this state, the slide member 6 is moved in the card discharge direction of the arrow C by the biasing force of the biasing member 5 as shown in FIG. When the card member 12 is slid to automatically return to the initial state, the card member 12 enters the card ejection state.
[0033]
The sliding member 7 at this time is automatically returned from the state shown in FIG. 10 to the initial state shown in FIG. 11 by being guided through the groove 8a on the left side of the lock portion 8b.
Further, the card member 12 in the overstroke state is pushed in the discharge direction indicated by the arrow C when the front end portion 12a is pushed by the contact portion 6a of the slide member 6, and the card discharge state as shown in FIG.
The slide member 6 when it is in the card ejection state collides with the stopper portion 2n by the urging force of the urging member 5 and stops, but the card member 12 that has moved in the ejection direction together with the slide member 6 is inertial. The force that tries to jump out in the direction of arrow C by force works.
[0034]
However, in the card member 12, the engaging portion 6b of the slide member 6 is elastically engaged with the concave portion 12g, and the lower surface 12c elastically contacts the elastic pressing portion 3 of the housing 2, as shown in FIG. The upper surface 12 d is in elastic contact with the card sliding contact plate 9 a of the cover member 9. Therefore, a brake is applied to the card member 12 to which a force to jump out in the discharge direction of the arrow C is applied, and the card member 12 can be prevented from jumping out of the housing 2.
[0035]
Further, as shown in FIG. 11, the engaging portion 6b that is elastically engaged with the recess 12g in the card ejected state is positioned on the regulating wall 2p. For this reason, an inertial force causes the card member 12 to jump out in the discharging direction indicated by the arrow C, and the engaging portion 6b that attempts to be elastically deformed on the lower side of the drawing abuts against the regulating wall 2p and has high rigidity. Thus, the card member 12 can be prevented from popping out more reliably.
Such a card connector device 1 according to the present invention has good operability because the card member 12 can be both loaded and ejected by a push / push operation of the card member 12.
[0036]
In the description of the embodiment of the present invention, the elastic pressing portion 3 is integrally formed with the housing 2, but the elastic pressing portion 3 may be an elastic body such as a sponge attached to the crosspiece 2h.
Further, the card member 12 has been described as being mounted and ejected by a push / push operation. However, an eject member (not shown) that can slide the slide member 6 in the direction of arrow B or arrow C is disposed. What you did is fine.
In addition, the left and right side plates 9b and 9c of the cover member 9 have been described with the attachment portion 9d that can be mounted on the printed circuit board 11 protruding from the bottom wall 2a of the housing 2 by a predetermined dimension to form a gap of dimension A. A protrusion that directly protrudes from the lower surface of the bottom wall 2a of the housing 2 may be formed to form a gap with a dimension A.
[0037]
【The invention's effect】
As described above, in the card connector device according to the present invention, the bottom wall of the housing in which the card mounting portion is formed is formed with the elastic pressing portion that can be elastically contacted with the lower surface of the card member. The card member can be prevented from popping out of the housing due to friction between the lower surface of the card member and the elastic pressing portion when ejected from the card mounting portion. Therefore, failure of the card member due to popping out can be prevented.
[0038]
In addition, when the housing is attached to a printable board , a predetermined gap is formed between the elastic pressing part and the printed board , so that the bottom wall of the housing can be elastically deformed into the gap portion, The card member can be smoothly inserted and attached.
[0039]
In addition, when the slide member in the locked state is once pressed in the mounting direction against the urging force of the urging member, the lock of the slide member is released, and the card member in the card mounted state is loaded into the card via the slide member. Since the card can be ejected from the card, it is possible to provide a card connector device with good operability that allows the card member to be mounted and ejected by pushing and pushing the card member.
[0040]
Further, the slide member in the card mounting state is locked with the sliding member positioned at the lock portion formed in the cam groove, and in this locked state, the lock is released by pressing the card member in the card mounting direction. Therefore, even if there is no eject member or the like, a card connector device can be provided and ejected by pushing and pushing the card member, and the structure is simple and the number of parts is small.
[0041]
Also, an opening is formed by hollowing out the bottom wall of the card mounting portion near the front end of the card member mounted on the card mounting portion, and the elastic pressing portion is a portion sandwiched between the entrance portion and the opening portion of the card mounting portion Since it is formed on the bottom wall of the card, it is possible to reliably prevent the card member from popping out during ejection by urging the elastic pressing portion with an appropriate elastic force.
[0042]
In addition, since the elastic pressing portion is formed so as to protrude toward the card member located on the bottom wall, the elastic pressing portion can be formed simultaneously when the housing is molded.
[0043]
Further, on the left and right side plates of the cover member, a mounting portion that can be mounted on the printed board is formed, and the mounting portion is protruded by a predetermined dimension from the bottom wall of the housing, so that a gap is formed between the bottom wall and the printed board. Therefore, a gap can be formed between the printed circuit board and the bottom wall of the housing simply by protruding the left and right side walls of the cover member from the bottom wall of the housing, and a card connector device that can be easily assembled can be provided.
