【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スティック等に書き込み、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ＩＣカードに、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用いられているＩＣカードは、内部のＩＣに接続された接触部を前端部側に整列形成した種類、あるいは接触部を一方の面に前後２列に整列形成した種類等がある。
【０００３】
そして、一方の面に接触部を前後２列に整列形成した種類のＩＣカードを使う場合は、前後２列の接触部にそれぞれ接触させるための複数の端子部材をカード用コネクタ装置のハウジング側に配設していた。
そして、ハウジングに配設した複数の端子部材は、一方側にＩＣカード側の接触部に接触させるための接点部を形成し、他端部側に端子部を形成し、前記端子部材の一部がハウジングにインサート成形等で埋設されて、端子部が外部に引き出し形成されている。そして、端子部が情報機器側のプリント基板にリフロー半田等で実装されて、従来のカード用コネクタ装置がプリント基板に取り付けられていた。
【０００４】
また、従来のカード用コネクタ装置は、ハウジング内部のカード装着部に装着したＩＣカードを検出するための検出スイッチが配設されており、この検出スイッチに接続されたスイッチ端子がハウジング外部に引き出されて、端子部材をプリント基板にリフロー半田して実装するときに、同時に情報機器側のプリント基板に実装していた。
このような従来のカード用コネクタ装置は、ハウジングの外部に引き出された端子部材の端子部、及び検出スイッチのスイッチ端子を情報機器側のプリント基板にリフロー半田等で１回の半田付け工程で同時に取り付けることができたので半田付けの作業性が良かった。
【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、樹脂材料からなるハウジングにインサート成形等で一体化した複数の端子部材、及びスイッチ端子等をリフロー半田等による一回の半田付け工程でプリント基板に実装していた。そのために、半田付け時に高温になった複数の端子部材の熱がハウジングに伝達されて、ハウジングに反り等の変形が発生するおそれがあった。
このような、半田付け時にハウジングが反ると、端子部材とプリント基板との間に隙間が発生して半田付け不良になるおそれがあった。
特に近年では、融点温度が従来の半田より高い、鉛フリー半田の使用率が高くなり、リフロー半田時の加熱温度が２７０℃程度に設定されることがあり、更に過酷な条件になっている。
【０００６】
また、複数の端子部材が、ハウジング外部に引き出されていたので、情報機器側のプリント基板の面積が大きくなり、従来のカード用コネクタ装置を用いた情報機器が大型になる問題があった。
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、実装時における半田付け不良をなくする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】

【００２０】
まず、本発明の１実施の形態のカード用コネクタ装置１は、図５に示すような、樹脂材料等の絶縁材で形成され、外形が略コ字状のコネクタ本体部２が配設されている。このコネクタ本体部２は、表面側が凹み形成されて平坦状の底面２ａと、この底面２ａの図示左側に形成した左側壁２ｂと、この左側壁２ｂと対向する側に形成した右側壁２ｃと、図示上方の後端壁２ｄとで３方が囲まれている。そして。底面２ａの中央部が略コ字状に切り欠きされて、ハウジング支持部３が形成されている。
【００２１】
前記コ字状に形成されたハウジング支持部３は、互いに対向する側面部３ａ、３ａと、奥側に後面部３ｂとが形成されて、図示下方の前端部側が開放されている。また、互いに対向する側面部３ａ、３ａの奥面部３ｂ近傍には、底面２ａを四角形状に切り欠いた切り欠き部３ｃ、３ｃが、互いに対向する位置に所定深さで切り欠き形成されている。
前記切り欠き部３ｃ、３ｃの外側の底面２ａには、後述するハウジング４を回動可能に支持する略半円形状の支持部３ｄ、３ｄが彫り込み形成されている。
【００２２】
このようなハウジング支持部３には、図６に示すような、外形が略矩形状のハウジング４が回動自在に支持可能になっていると共に、ハウジング４を係止して動きを規制するようになっている。
前記ハウジング４は、樹脂材料等の絶縁材料で形成され、図６Ａに示す下方の前端部４ａ側が開放されて、後述する第１カード部材１４を装着可能な第１カード装着部５が形成されている。
【００２３】
この第１カード装着部５は、図６Ｃに示すように、下部には平坦状の底壁５ａが形成され、この底壁５ａの図示左右には、後述する第１カード部材１４をガイド可能な、互いに対向する側壁５ｂ、５ｂが形成され、この側壁５ｂ、５ｂの上部には側壁５ｂ、５ｂの奥行き方向に沿って上部壁５ｃ、５ｃが形成されて、第１カード装着部５の左右にコ字状のガイド溝５ｄが形成されており、このガイド溝５ｄに後述する第１カード部材１４が装着可能になっている。
また、第１カード装着部５は、図６Ａに示す上方の奥側に奥壁５ｅが形成されて、挿入される第１カード部材１４の前側部１４ａが当接可能になっている。
【００２４】
また、ハウジング４は、第１カード装着部５に後述する第１カード部材１４を挿入する側である前端部４ａ寄りの側壁５ｂ、５ｂの外面に、それぞれ舌片状の係止部材５ｆ、５ｆが突出形成されている。
前記係止部材５ｆ、５ｆは、舌片状の板バネからなり、一端部側を側壁５ｂの下部にインサート成型等で埋設すると共に、他端部側を側壁５ｂから上方に向けて突出形成している。
そして、係止部材５ｆは、側壁５ｂから外側に突出する部分を上方に撓み変形させて形成されている。
【００２５】
前記係止部材５ｆは、図６Ｃに示すように、他端部側である上端部側が側壁５ｂから離れる方向に斜めになって、側壁５ｂ側に弾性変形可能になっている。
また、ハウジング４は、奥壁５ｅ近傍の左右の側壁５ｂ、５ｂから外側に向かって、一対の回動支持部５ｇ、５ｇが突出形成されている。
この回動支持部５ｇは、円柱状に形成され、コネクタ本体部２の半円状の支持部３ｄに支持されて回動可能になっている。
【００２６】
また、図６Ａに示すように、回動支持部５ｇ、５ｇに隣接する上方側には、抜け止め部５ｈ、５ｈが突出形成されている。
そして、ハウジング４を、コネクタ本体部２の底面２ａに対して略直立させた状態で、抜け止め部５ｈを切り欠き部３ｃに嵌合させると、回動支持部５ｇが支持部３ｄに嵌合し、ハウジング４が回動支持部５ｇを支点として、ハウジング支持部３に回動自在に支持可能になっている。
このようにハウジング支持部３に支持されて回動自在のハウジング４は、図１５に示すように、抜け止め部５ｈが切り欠き部３ｃ上部の底面を構成する壁部材に当接することにより、ハウジング支持部３から抜け止めされている。
【００２７】
また、ハウジング４の前端部４ａ寄りには、底壁５ａを貫通する複数の第１開口部４ｂが手前側と奥側の前後２列に整列形成されている。この第１開口部４ｂは、後述する第１カード部材１４の接触部１２ｃの数に対応して、例えば６個形成されている。
また、第１カード装着部５の奥側には、奥壁５ｅに接して底壁５ａを貫通する第２開口部４ｃが１個形成されている。
【００２８】
前記複数の第１開口部４ｂ内には、第１端子部材６がそれぞれ配設されている。この第１端子部材６は、弾性を有する金属板からなり、図８、９に示すように、一端部側に形成した階段状の基部６ａと、この基部６ａから一方側に延長形成した片持ち梁状の第１、第２腕部６ｂ、６ｃとからなり、この第１、第２腕部６ｂ、６ｃは、先端部側が互いに離れる方向に湾曲形成されている。

【００２９】
このような第１開口部４ｂ内に配設された第１端子部材６は、図１５の要部断面図に示すように、基部６ａがインサート成形等により底壁５ａに埋設され、この基部６ａから延長形成されて第１開口部４ｂ内に露出させた片持ち梁状の第１、第２腕部６ｂ、６ｃが配設されている。
そして、第１、第２腕部６ｂ、６ｃは、後述するカード部材である第１カード部材１４を第１カード装着部５に挿入する時の挿入方向と平行に配設されている。
また、互いに離れる方向に湾曲形成されたカード接点部６ｄと可動接点部６ｅとは、カード接点部６ｄが第１開口部４ｂから上方に飛び出し、可動接点部６ｅが第１開口部４ｂから下方に飛び出した状態になっている。
【００３０】
また、第２開口部４ｃ内には、弾性を有する金属板からなるスイッチ端子７が配設されている。このスイッチ端子７は、図１０、１１に示すように、左側に形成した基部７ａと、この基部７ａから一方側である図示右方向に延長形成してスイッチ端子用第１、第２腕部７ｂ、７ｃが設けられている。
前記スイッチ端子用第１腕部７ｂは、基部７ａ側に対して先端部側が幅広に形成されており、この幅広部分を３つ股状に分割して形成され、中央部のカード弾接部７ｄが上方側に湾曲形成されており、このカード弾接部７ｄを下方に押圧すことにより、スイッチ端子用第１腕部７ｂが下方に弾性変形するようになっている。
【００３１】
また、中央部のカード弾接部７ｄの両隣には、プリント基板の表面に形成した一対の固定接点部（図示せず）の一方側に弾接可能な可動接点部７ｅ、７ｅが一対形成されている。そして、カード弾接部７ｄと可動接点部７ｅ、７ｅとは、互いに離れる方向に湾曲形成されている。
また、スイッチ端子用第２腕部７ｃは、プリント基板に形成した一対の固定接点部の他方側に弾接する弾接部７ｆが下方側に湾曲形成されている。前記弾接部７ｆは、延長形成された第２腕部７ｃが途中から下方側に折り曲げて、可動接点部７ｅより下方に位置している。
【００３２】
このようなスイッチ端子７は、図１５の要部断面図に示すように、基部７ａが底壁５ａにインサート成形等で埋設され、基部７ａから延長形成して第２開口部４ｃ内に露出させた片持ち梁状の一対のスイッチ端子用腕部７ｂ、７ｃが配設され、この一対のスイッチ端子用腕部７ｂ、７ｃは、後述する第１カード部材１４を第１カード装着部５に挿入する時の挿入方向と平行に配設されている。
また、スイッチ端子７は、図１５に示すように、第２開口部４ｃ内に延出する片持ち梁状のスイッチ端子用第１腕部７ｂのカード弾接部７ｄが、第２開口部４ｃから上方に飛び出しており、可動接点部７ｅ、７ｅは、第２開口部４ｃ内に位置して第２開口部４ｃ内に沈んだ状態になっている。
そして、カード弾接部７ｄを下方に押圧すると、スイッチ端子用第１腕部７ｂが下方に弾性変形して、一対の可動接点部７ｅ、７ｅが第２開口部４ｃから下方に出っ張るようになっている。
【００３３】
また、コネクタ本体部２は、図５に示すように、表面側の底面２ａを所定量へこませて、後端壁２ｄと、互いに対向する左側壁２ｂと右側壁２ｃとに囲まれた部分の底面２ａ上に、第２カード装着部８が形成されている。
この第２カード装着部８は、ハウジング２の表面側を所定量凹ませて形成されて前方側が開放されており、この前方側の開放部分から後述する第２カード１３が挿入されて装着可能になっている。
【００３４】
また、後端壁２ｄには、複数の第２端子部材９が埋設形成され、この第２端子部材９の一端部側が、第２カード装着部８の内方に向けて露出して片持ち梁状に延出形成されている。そして、片持ち梁状の先端部が上方側に湾曲形成されて接点部９ａが形成されている。
この接点部９ａは、先端部が底面２ａに当接しており、湾曲形成された接点部９ａに上方から押圧荷重が加わると、接点部９ａが延びる方向に弾性変形可能となっている。
【００３５】
また、第２端子部材９は、他端部側が後端壁２ｄから外方に突出して、図２に示すような端子部９ｂが、Ｌ字状に折り曲げ形成されている。この端子部９ｂが情報機器側のプリント基板（図示せず）にリフロー半田等で実装可能になっている。
また、右側壁２ｃ寄りの底面２ａ上には、第２カード装着部８に挿入される後述する第２カード１５と共に後端壁２ｄ方向にスライド移動可能なスライド部材１０と、このスライド部材１０を手前側の前端部側に弾性付勢可能なコイルバネ１１とが配設されている。前記スライド部材１０は、略４５度の角度で傾斜する傾斜面１０ａが形成されている。
また、図５に示すコネクタ本体部２の左側壁２ｂ、右側壁２ｃの下方側には、金属板からなる半田付け部１６がインサート成型等により形成されている。
そして、半田付け部１６及び第２端子部材９の端子部９ｂを情報機器側のプリント基板（図示せず）にリフロー半田等することにより、本発明のカード用コネクタ装置１が実装可能になっている。
【００３６】
また、本発明のカード用コネクタ装置１は、ハウジング支持部３にハウジング４を回動自在に支持した状態のコネクタ本体部２の上部に、金属板からなるカバー１２が配設されて、コネクタ本体部２の上部がカバー１２で覆われている。
このカバー１２は、図１に示すように、２個の矩形状の開口部１２ａ、１２ａと、第２カード装着部８に装着した第２カード１３の上面に当接可能な舌片部１２ｂ、１２ｃとが形成されている。
このようなカバー１２は、図１に示すように、左右側端部を下方側に折り曲げて折り曲げ部１２ｄを形成し、この折り曲げ部１２ｄがコネクタ本体部２の左右の側壁２ｂ、２ｃにスナップ係合させて取り付けられている。
【００３７】
また、コネクタ本体部２は、図２、３に示すように、裏面側から下方に向けて突出する位置決め突起１３が形成されている。この位置決め突起１３は、プリント基板（図示せず）側の位置決め穴に嵌合可能になっており、本発明のカード用コネクタ装置１を情報機器側のプリント基板に実装するときに位置決めして仮止め可能になっている。
また、第１カード装着部５には、内部にＩＣ（集積回路）を埋設した、記録媒体として一般的に使用されている公知の第１カード部材１４が装着可能になっている。
【００３８】
この第１カード部材１４は、図１３に示すように、前側部１４ａの一方のコーナ部１４ｂが面取り状に斜めにカットされて、前側部１４ａ側が非対称形状になって、第１カード装着部５への第１カード部材１４の逆挿入を防止するようになっている。
また、第１カード部材１４の一方の面である図示上面には、内部のＩＣ（図示せず）に導通する複数の接触部１４ｃが露出して２列に整列形成されている。
また、第２カード装着部８には、第１カード部材１４より表面積の大きな第２カード部材１５が装着可能になっている。
【００３９】
前記第２カード部材１５は、図１４に示すように、前側部１５ａ寄りの一方の面である下面側に、内部のＩＣ（図示せず）に導通する複数の接触部１５ｂが露出して１列に整列形成されている。
また、前側部１５ａの一方のコーナ部１５ｃが斜めに面取り状にカットされて、前側部１５ａが非対称形状となっている。
そのために、第２カード１５を第２カード装着部８に挿入すると、コーナ部１５ｃが、スライド部材１０の傾斜面１０ａに当接して、第２カード装着部８に装着する第２カード１５の逆挿入を防止するようになっている。
【００４０】
このような構成の本発明のカード用コネクタ装置１の組立は、図５に示すような、スライド部材１０とコイルバネ１１とを取り付けた状態のコネクタ本体部２のハウジング支持部３に、ハウジング４を位置させる。
前記ハウジング４は、コネクタ本体部２の底面２ａに対して略直立させることにより、抜け止め部５ｈが切り欠き部３ｃに嵌合して挿通すると共に、円柱状の回動支持部５ｇが半円状の支持部３ｄに位置して嵌合する。
【００４１】
この状態で、ハウジング４を反時計回り方向に回動させると、回動支持部５ｇを支点としてハウジング４が回動し、左右の側壁５ｂ、５ｂから外側に突出する係止部材５ｆ、５ｆが、図４に示すように、ハウジング支持部３の側面部３ａ、３ａに当接して、ハウジング４の反時計回り方向への回動がストップする。
この時のハウジング４は、図１５に示すように、奥壁５ｅに対して前端部４ａ側が持ち上がった傾斜状になってコネクタ本体部２に支持される。
【００４２】
このコネクタ本体部２に傾斜状に支持されたハウジング４は、回動支持部５ｇ、および抜け止め部５ｈによって、コネクタ本体部２のハウジング支持部３から抜け止めされて、回動支持部５ｇを支点として回動自在になっている。
また、図１５に示す傾斜状のハウジング４を、底面２ａに対して直立させる方向の時計回り方向に回動させると、ハウジング４はコネクタ本体部２から着脱できるようになっている。
次に、ハウジング４を傾斜状に支持したコネクタ本体部２の上方からカバー１２をかぶせてスナップ係合させるとにより、本発明のカード用コネクタ装置１の第１次組立が終了する。
【００４３】
次に、本発明のカード用コネクタ装置１を情報機器等のプリント基板（図示せず）にリフロー半田等で実装する第２次組立について説明する。
まず、コネクタ本体部２の裏面側の２本の位置決め突起１３を、プリント基板の位置決め穴（図示せず）に嵌合させて、カード用コネクタ装置１をプリント基板に仮止めする。
すると、コネクタ本体部２の後端壁２ｄから後方に突出する複数の第２端子部材９の端子部９ｂが、プリント基板側に形成している複数の端子パターン（図示せず）に当接、または近接する。
また、一対の半田付け部１６がプリント基板側の半田ランドに当接、または近接する。
【００４４】
この時のハウジング４は、前端部４ａ側が上方に持ち上がった傾斜状になっているので、ハウジング４の背面から下方に出っ張った第１端子部材６の可動接点部６ｅは、プリント基板から離間した状態になっている。
この状態で、コネクタ本体部２の複数の第２端子部材９及び半田付け部１６をプリント基板にリフロー半田等で半田付けすることにより、本発明のカード用コネクタ装置１がプリント基板に実装される。
このプリント基板にコネクタ本体部２を実装時は、ハウジング４が斜めになっているので、複数の第１端子部材６がプリント基板から離間している。
【００４５】
前記カード用コネクタ装置１を実装したプリント基板が常温まで冷却されると、係止部材５ｆの弾性力に抗して、傾斜状のハウジング４の前端部４ａ側を下方に押圧する。
すると、係止部材５ｆがハウジング支持部３の側面部３ａに押されて側壁５ｂの外面に密着するように弾性変形して、係止部材５ｆがハウジング支持部３の側面部３ａを通過して、ハウジング４が水平状態になる。
このようにハウジング４が水平状態になると、図３に示すように、係止部材５ｆは、自身の弾性力で初期状態に復帰して、先端部が側面部３ａを構成する壁部の下面に当接して、ハウジング４の動きが規制されて、ハウジング４ががコネクタ本体部２に係止される。
【００４６】
前記ハウジング４が水平状態となってコネクタ本体部２に係止されると、第１端子部材６の可動接点部６ｅがプリント基板側の固定端子に弾接して、ハウジング４は、上方に回動しょうとする力が働くが、係止部材５ｆによって、動きが規制されている。
この時のスイッチ端子７の第２腕部７ｃに形成した弾接部７ｆは、プリント基板の他方の固定接点部に弾接している。
そして、プリント基板に実装した本発明のカード用コネクタ装置１のハウジング４の第１カード装着部５に、第１カード部材１４を挿入して装着すると、第１カード部材１４の接触部１４ｃに第１端子部材６のカード接点部６ｄが弾接して、プリント基板側の固定端子と第１カード部材１４の接触部１４ｃとが第１端子部材６を介して電気的に導通される。
