Description

【０００１】
【発明の属する技術分野】
この発明は、プリント基板実装装置及びプリント基板実装方法に係り、詳しくは、プリント基板を水平方向に着脱可能に実装するように構成して成るプリント基板実装装置及びプリント基板実装方法に関する。
【０００２】
【従来の技術】
ＩＣ（半導体集積回路）、トランジスタ、コンデンサ、抵抗、インダクタ等の各種の電子部品を用いることにより、コンピュ−タのような情報処理機器を含む各種の電子機器が組み立てられている。このような電子機器の組立には、予め所望の回路パターンが印刷されたプリント基板（第１のプリント基板）がマザーボード、メインボード等と称される主プリント基板（第２のプリント基板）に電気的に接続されて成るプリント基板群が用いられて、第１及び第２のプリント基板のいずれか片面に、あるいは両面に上記したような電子部品が取り付けられる。ここで、電子機器の組立を行う場合に、あるいは修理、電子部品の取換え等のメンテナンスを行う場合に、第１のプリント基板の取り付けあるいは取り外し（以下、着脱とも称する）を容易にするために、第１のプリント基板はコネクタを介して第２のプリント基板に着脱可能に接続される。
【０００３】
図２１は、上述したようなプリント基板群によって組み立てられた電子機器の一例を概略的に示す図である。同電子機器１００は、図２１に示すように、筐体１０１内が複数のモジュール室１０２により区切られて、各モジュール室１０２には第１のプリント基板１０３がコネクタ１０４を介して第２のプリント基板１０５に接続されて成るプリント基板群１０６が配置されている。第１及び第２のプリント基板１０３、１０５には、電子機器１００としての機能を実現するための電気回路を構成する各種の電子部品１０７が取り付けられている。そして、第１のプリント基板１０３は着脱可能にコネクタ１０４に実装されている。同プリント基板１０３の端部には外部と電気信号をやり取りするための外部信号接続用コネクタ１０８が設けられている。説明を簡単にするために、図２１の構成では一つのモジュール室１０２のみにプリント基板群１０６を配置した例で示している。
【０００４】
ところで、従来においては、上述したように第１のプリント基板１０３をコネクタ１０４に着脱する場合は、図２２に示すように、所望のモジュール室１０２を筐体１０１から前面方向（例えば図示の右方向）に引き出してから、同プリント基板１０３をコネクタ１０４に対して垂直方向（上下方向）に取り付け、あるいは取り外しすることが行われている。
しかしながら、そのためには筐体１０１の前面に垂直方向の余分の作業スペースを確保しなければならないので、作業場所が制約されるという問題が生ずる。また、電子機器１００を稼働した状態で同プリント基板１０３の着脱を行うことが効率的であるが、このためには、プリント基板群１０６に接続されている各種のケーブル類を外部に引き出さなければならないので、引き出すのに必要なケーブル類の余長を予めとっておく必要がある。さらに、ケーブル類をスムーズに引き出すためのガイド機構も必要になる。
【０００５】
上述したようにプリント基板を着脱可能にコネクタに実装する場合、プリント基板を垂直方向にではなく水平方向に着脱するように構成したコネクタ（プリント基板実装装置）が開示されている（例えば、特許文献１参照。）。図２３及び図２４は同コネクタを示す斜視図、図２５は同コネクタを用いて組み立てた電子機器（パーソナルコンピュ−タ）を概略的に示す図である。同コネクタ１１０は、図２３及び図２４に示すように、プリント基板１２１を実装すべきスリット１１１の一方端に開放部１１２が設けられて、この開放部１１２からスリット１１１に沿ってプリント基板１２１を水平方向に着脱可能に実装するように構成されている。そして、開放部１１２の反対側に摺動可能に設けた押出し部１１３をプリント基板１２１の端子部１２２が押すことにより、揺動部１１４の一端が押出し部１１３の斜面１１５に押されて支持部１１６回りに回転して中間部１１７が押圧板１１８を内側に押し、押圧板１１８がスリット１１１の両側に配置されたコネクタ端子を押してスリット１１１内の端子部の基板端子に接触させるように構成されている。
【０００６】
図２３及び図２４のコネクタ１１０を用いて組み立てられたパーソナルコンピュ−タ１２０は、図２５に示すように、コネクタ１１０がマザーボード１１９上に取り付けられて、コネクタ１１０の開放部１１２からプリント基板１２１の端子部１２２をスリット１１１に挿入することにより、プリント基板１２１がコネクタ１１０に実装されている。
上述したようなコネクタ１１０によれば、プリント基板１２１を水平方向に着脱可能に実装するので、前述したような作業場所が制約されるという問題を改善することができ、またケーブル類の余長を予めとっておいたり、ケーブル類のガイド機構を設ける等の余分な手間を不要にして、電子機器を稼働した状態でプリント基板の着脱を行うことができるようになる。

【発明が解決しようとする課題】
ところで、従来のプリント基板実装装置では、プリント基板を垂直方向にではなく水平方向に着脱可能に実装するように構成されているので、作業スペースの点で有利になるものの、異なる種類のプリント基板を誤実装し易い、という問題がある。
すなわち、図２１に示したようにプリント基板群１０６によって電子機器１００を組み立てる場合、特許文献１に示されたようなコネクタ１１０を用いてプリント基板を水平方向に実装すれば実装作業が容易になるが、図２１のコネクタ１０４に実装されるプリント基板１０３は用途に応じて仕様の異なる複数種類のものが用意されるので、目的のものと異なる種類の他のプリント基板を誤実装し易くなる。したがって、プリント基板をコネクタに誤実装したままで電子機器を稼働させてしまう可能性があり、電子機器を誤動作させるおそれがあるので、電子機器の信頼性を損ねることになる。
【０００９】
この発明は、上述の事情に鑑みてなされたもので、プリント基板を水平方向に着脱可能に実装する構成において、プリント基板の誤実装を確実に防止することができるようにしたプリント基板実装装置及びプリント基板実装方法を提供することを目的としている。

【００２１】
【発明の実施の形態】
以下、図面を参照して、この発明の実施の形態について説明する。説明は実施例を用いて具体的に行う。
図１は、この発明の一実施例であるプリント基板実装装置の構成を概略的に示す示す斜視図、図２は図１のＡ−Ａ矢視断面図、図３は図１のＢ−Ｂ矢視断面図、図４は図１のＣ−Ｃ矢視断面図、図５は同プリント基板実装装置を構成する第２の実装部材を示す平面図、図６は図５のＤ−Ｄ矢視断面図、図７は同プリント基板実装装置に実装されるプリント基板の一例を示す正面図である。
この例のプリント基板実装装置１０は、図１に示すように、プリント基板の挿入方向であるＸ方向（長手方向）に沿って開口４が設けられ、Ｘ方向と直交するＹ方向（短手方向）に沿って凹状の断面形状を有する絶縁性の第１の実装部材１と、第１の実装部材１の開口４内にＸ方向に沿って摺動可能に配置され、Ｘ方向に沿ってプリント基板を挿入するためのスリット５が設けられたＹ方向に沿って凹状の断面形状を有する絶縁性の第２の実装部材２と、第２の実装部材２のスリット５にプリント基板が挿入されたとき、第１の実装部材１と第２の実装部材との間に挿入方向に沿って挿入されて、プリント基板に設けられている誤実装防止用溝に嵌合される可撓性の誤実装チェック板３とを備えている。
【００２２】
第１の実装部材１は樹脂、セラミックス等の絶縁材料から成り、図１及び図２に示すように、Ｘ方向に沿って伸びる一対の側板６、７及び両側板６、７を結合する底板８を有し、両側板６、７には細長状の複数の接続端子１１、１２がＸ方向に沿ってそれぞれ上端部１１Ａ、１２Ａを内面に露出するように、下方（縦方向Ｚ）に向かうように設けられている。ここで、接続端子１１、１２としては、実装されるプリント基板の端子と良好な接触を確保するために、銅のように弾力性に優れた導電材料が用いられる。また、第１の実装部材１の底板８の内面には、図１〜図３に示すように、Ｘ方向に沿って誤実装チェック板３を挿入するためのガイド溝９が途中位置まで設けられて、ガイド溝９の端部９Ａの表面は誤実装チェック板３を滑らかに挿入できるように曲面に加工されている。
【００２３】
第２の実装部材２は樹脂、セラミックス等の絶縁材料から成り、図１及び図４に示すように、Ｘ方向に沿って伸びる一対の側板１３、１４及び両側板１３、１４を結合する底板１５を有し、両側板１３、１４にはそれぞれ、第１の実装部材１に設けられている接続端子１１、１２のピッチＰ１と同じピッチＰ２で、かつ同接続端子１１、１２と同数の細長状の複数の貫通孔１６、１７が、Ｘ方向に沿って設けられている。また、第２の実装部材２のＹ方向に沿った幅寸法は、第２の実装部材２が第１の実装部材１の開口４内に配置された際に、摺動可能となるように開口４の幅寸法よりもやや小さくなるように選ばれている。また、第２の実装部材２の底板１５には、図５及び図６に示すように、Ｘ方向に沿った途中位置に誤実装チェック板３を挿入するためのガイド溝１８が設けられて、このガイド溝１８は大きい幅の第１の溝１８Ａ（奥側）と小さい幅の第２の溝１８Ｂ（手前側）とにより構成されている。
【００２４】
誤実装チェック板３はアルミニウム、樹脂等の薄板から成り、図１に示すように、挿入方向であるＸ方向に向かって左側縁の途中位置に切欠け部１９が設けられ、この切欠け部１９は、図５に示すように、第２の実装部材２の底板１５に設けられているガイド溝１８の第２の溝１８Ｂに接している突出部１５Ａに対応して形成される。この誤実装チェック板３の切欠け部１９は、後述するように、プリント基板を実装する際に、第２の実装部材２のガイド溝１８との係合状態を変化させることによって、実装されるプリント基板の接続状態を切り替えるように構成されている。このような誤実装チェック板３を用いることにより、プリント基板の誤実装を確実に防止することができるようになる。なお、この例のプリント基板実装装置１０に実装されるプリント基板は、誤実装チェック板３を嵌合するための誤実装防止用溝が設けられていることが前提要件となる。
【００２５】
図７は、この例のプリント基板実装装置１０に実装されるプリント基板の一例を示す正面図である。同プリント基板２０は、図７に示すように、基板のいずれか片面に、あるいは両面には所望の電子部品２１が取り付けられて、下端部にはプリント基板実装装置１０の第１の実装部材１の接続端子１１、１２にそれぞれ接続するための複数の接続端子２２（２３）が設けられる。但し、接続端子２３は裏面側に設けられている。また、外部と電気信号をやり取りるための外部信号接続用コネクタ２４が側面部に設けられる。そして、接続端子２２（２３）に隣接する所望の位置には、上述したような誤実装チェック板３を嵌合するための誤実装防止用溝２５が設けられる。この誤実装防止用溝２５を設ける位置は、第２の実装部材２の底板１５に設けられているガイド溝１８と対応する位置が選ばれる。
【００２６】
次に、図８〜図１６を参照して、この例のプリント基板実装装置１０を用いてプリント基板を実装する方法を工程順に説明する。なお、図９〜図１３において、（ａ）は図８のＥ−Ｅ矢視断面図に相当した断面図を、（ｂ）は図８のＦ−Ｆ矢視断面図に相当した断面図を、（ｃ）は上面図を示している。
まず、図８に示すように、第１の実装部材１の開口４内に第２の実装部材２をＸ方向に沿って摺動可能に配置する。この場合、図９（ａ）〜（ｃ）に示すように、第１の実装部材１の底板８に設けられているガイド溝９の端部９Ａに対して、第２の実装部材２の底板１５に設けられているガイド溝１８の奥側の第１の溝１８Ａの端部が一致するように配置する。なお、第１の実装部材１は、予めその接続端子１１、１２を介してマザーボード、メインボード等の第２のプリント基板（図示せず）に接続しておくものとする。
【００２７】
次に、図１０（ａ）〜（ｃ）に示すように、誤実装チェック板３をＸ方向に沿って第１の実装部材１の底板８のガイド溝９に押し込むようにして挿入する。ガイド溝９の端部９Ａに到達した誤実装チェック板３の先端部は、端部９Ａが曲面に加工されているので滑らかにガイドされて、第２の実装部材２の底板１５のガイド溝１８の第１の溝１８Ａまで達する。この状態で誤実装チェック板３はガイド溝及びガイド溝１８の第１の溝１８Ａと係合しているので、抜け落ちることはない。
【００２８】
次に、図１１（ａ）〜（ｃ）に示すように、図７に示したような実装すべきプリント基板２０をＸ方向に沿って第２の実装部材２のスリット５に挿入する。すなわち、図１４に示すように、両側に接続端子２２、２３を有するプリント基板２０を、対応した第１の実装部材１の接続端子１１、１２と接続する前段階として、第２の実装部材２のスリット５に摺動させながら挿入する。そして、図１１（ａ）に示すように、第２の実装部材２の底板１５のガイド溝１８の第１の溝１８Ａに対して、誤実装防止用溝２５が一致するように、プリント基板２０を位置決めする。
【００２９】
次に、図１２（ａ）〜（ｃ）に示すように、誤実装チェック板３をさらに押し込んで、その先端部をプリント基板２０の誤実装防止用溝２５に嵌合させる。
ここで、上述したようにプリント基板２０の誤実装防止用溝２５に誤実装チェック板３を嵌合した状態では、図１５に示すように、第２の実装部材２の両板１３、１４の複数の貫通孔１６、１７の位置を、各貫通孔１６、１７がいずれも第１の実装部材１の両側板６、７にそれぞれ設けられている複数の接続端子１１、１２からずれる関係となるように、予め設定しておくものとする。したがって、図１５に示したように、対向する関係となるように配置されている第１の実装部材１の接続端子１１、１２と、プリント基板２０の接続端子２２、２３との間には、絶縁性の第２の実装部材２が介在されることになるので、プリント基板２０の接続端子２２、２３はそれぞれプリント基板実装装置１０の接続端子１１、１２と非導通となる。なお、図１５では、説明を簡単にするために、第１及び第２の実装部材１、２のそれぞれの片側の側板６、１３と、プリント基板２０の片側の接続端子２３との対応関係についてのみ示している。
【００３０】
次に、図１３（ａ）〜（ｃ）に示すように、第２の実装部材２をＸ方向に沿って距離Ｌだけ摺動させる。この結果、誤実装チェック板３は、先端部がプリント基板２０の誤実装防止用溝２５に嵌合されていて固定されているので、第２の実装部材２が摺動してもこれと一体にＸ方向に移動することができない。したがって、誤実装チェック板３は、図１３（ｃ）に示すように、ガイド溝１８内で距離Ｌだけ第１の溝１８Ａから第２の溝１８Ｂに移動することになるので、ガイド溝１８との係合状態が変化することになる。
ここで、上述したように第２の実装部材２が距離Ｌだけ摺動した状態では、図１６に示すように、第２の実装部材２の両板１３、１４の複数の貫通孔１６、１７の位置を、各貫通孔１６、１７がいずれも第１の実装部材１の両側板６、７にそれぞれ設けられている複数の接続端子１１、１２と一致する関係となるように、予め設定しておくものとする。したがって、図１６に示したように、対向する関係となるように配置されている第１の実装部材１の接続端子１１、１２と、プリント基板２０の接続端子２２、２３とは、その弾力性により貫通孔１６、１７内に突出した各接続端子１１、１２により接続されることになるので、プリント基板２０の接続端子２２、２３はそれぞれプリント基板実装装置１０の接続端子１１、１２と導通する。なお、図１６では、説明を簡単にするために、第１及び第２の実装部材１、２のそれぞれの片側の側板６、１３と、プリント基板２０の片側の接続端子２３との対応関係についてのみ示している。
【００３１】
第２の実装部材２の両側板１３、１４にそれぞれ設けられている貫通孔１６、１７は、第１の実装部材１の両側板６、７にそれぞれ設けられている接続端子１１、１２と、プリント基板２０の接続端子２２、２３との間の接続状態を切り替えるように作用している。
【００３２】
上述のようにして、プリント基板２０の実装が終了するので、電子機器が稼働状態にあるときは、プリント基板は即動作するようになる。
ここで、もし、誤実装防止用溝２５が設けられないプリント基板、あるいは誤実装防止用溝２５が所定の位置に設けられていないプリント基板を実装したときは、図１２（ａ）〜（ｃ）に相当した工程において、誤実装チェック板３の先端部がプリント基板に嵌合されなくなる。したがって、この状態で、図１３（ａ）〜（ｃ）に相当した工程において、第２の実装部材２をＸ方向に摺動したとすると、誤実装チェック板３はプリント基板２０により固定されていないので、第２の実装部材３と一体にＸ方向に移動するようになり、図１３（ａ）〜（ｃ）に示したように、ガイド溝１８内で距離Ｌだけ第１の溝１８Ａから第２の溝１８Ｂに移動することができなくなる。すなわち、図１７に示すように、誤実装チェック板３は第２の実装部材２がＸ方向に摺動しても、ガイド溝１８の第１の溝１８Ａに留まったままで、第２の溝１８Ｂに移動することはできない。したがって、所望の距離Ｌだけ移動できないので、前述したように、第１の実装部材１の接続端子１１、１２と、プリント基板２０の接続端子２２、２３とを複数の貫通孔１６、１７を通じて導通させることができなくなる。
【００３３】
なお、プリント基板２０をプリント基板実装装置１０から取り外す場合は、図１３（ａ）〜（ｃ）の状態から、第２の実装部材２を逆の方向に距離Ｌだけ摺動させて、図１２（ａ）〜（ｃ）の状態の元の位置に戻すようにする。これによって、第１の実装部材１の接続端子１１、１２とプリント基板２０の接続端子２２、２３との間を非導通にしてから、誤実装チェック板３を第１の実装部材１のガイド溝９に沿って引き出した後に、プリント基板２０を取り外すようにする。
【００３４】
図１８は、上述のようにプリント基板２０を水平方向に着脱可能に実装するようにして、モジュール室２６にプリント基板２０（第１のプリント基板）がプリント基板実装装置１０を介して第２のプリント基板２７に接続されて成るプリント基板群２８を配置することにより、電子機器２９を組み立てる例を示すものである。第１及び第２のプリント基板２０、２７には、電子機器２９としての機能を実現するための電気回路を構成する各種の電子部品２１が取り付けられている。図１９はモジュール室２６の拡大図を示し、このモジュール室２６には複数のプリント基板２０がそれぞれ、図２０に示すように、プリント基板実装装置１０に実装される。
【００３５】
上述したように、この例によれば、所望の位置に誤実装防止用溝２５が設けられた目的とするプリント基板２０以外の異なる種類のプリント基板が実装されたときは、第１の実装部材１の接続端子１１、１２と、プリント基板２０の接続端子２２、２３とを導通させることがなくなるので、プリント基板の誤実装を確実に防止することができるようになる。したがって、プリント基板を誤実装したままで電子機器を稼働させてしまう可能性はなくなり、電子機器を誤動作させることがなくなるので、電子機器の信頼性を向上させることができる。
【００３６】
また、プリント基板２０は、図１２（ａ）〜（ｃ）に示すように、誤実装防止用溝２５に誤実装チェック板３が嵌合されてプリント基板実装装置１０に実装された時点では、図１５に示したように、第１の実装部材１の接続端子１１（１２）とプリント基板２０の接続端子２３（２２）との間は非導通になっている。そして、プリント基板２０は、図１３（ａ）〜（ｃ）に示すように、その後に第２の実装部材２を摺動させて誤実装チェック板３を第２の実装部材２のガイド溝１８内で距離Ｌだけ第１の溝１８Ａから第２の溝１８Ｂに移動させることにより、図１６に示したように、第１の実装部材１の接続端子１１（１２）とプリント基板２０の接続端子２３（２３）との間を導通させている。したがって、電子機器２９を稼働した状態でプリント基板２０を実装しても、上記接続端子１１、１２と上記接続端子２２、２３との間の接触状態を安定にしてから、プリント基板２０を動作させるので、プリント基板実装時の接触抵抗を低減できるという効果が得られる。

[Prior art]
2. Description of the Related Art Various electronic devices including information processing devices such as computers have been assembled by using various electronic components such as ICs (semiconductor integrated circuits), transistors, capacitors, resistors, and inductors. To assemble such an electronic device, a printed circuit board (first printed circuit board) on which a desired circuit pattern is printed in advance is electrically connected to a main printed circuit board (second printed circuit board) called a motherboard, a main board, or the like. The electronic components as described above are attached to one or both surfaces of the first and second printed circuit boards by using a group of printed circuit boards that are electrically connected. Here, when assembling an electronic device or performing maintenance such as repair or replacement of an electronic component, the first printed circuit board is easily attached or detached (hereinafter, also referred to as detachment). The first printed circuit board is detachably connected to the second printed circuit board via a connector.
[0003]
FIG. 21 is a diagram schematically illustrating an example of an electronic device assembled by the above-described printed circuit board group. In the electronic device 100, as shown in FIG. 21, the inside of a housing 101 is divided by a plurality of module rooms 102, and a first printed circuit board 103 is provided in each module room 102 via a connector 104 for a second print. A printed board group 106 connected to the board 105 is arranged. Various electronic components 107 constituting an electric circuit for realizing the function as the electronic device 100 are attached to the first and second printed circuit boards 103 and 105. The first printed circuit board 103 is detachably mounted on the connector 104. An external signal connection connector 108 for exchanging electric signals with the outside is provided at an end of the printed circuit board 103. For the sake of simplicity, the configuration of FIG. 21 shows an example in which the printed circuit board group 106 is arranged only in one module room 102.
[0004]
By the way, conventionally, when the first printed circuit board 103 is attached to or detached from the connector 104 as described above, as shown in FIG. ), The printed circuit board 103 is attached to or detached from the connector 104 in the vertical direction (up and down direction) with respect to the connector 104.
However, for this purpose, an extra work space in the vertical direction must be ensured on the front surface of the housing 101, so that there is a problem that the work place is restricted. It is efficient to attach and detach the printed circuit board 103 while the electronic device 100 is operating. For this purpose, various cables connected to the printed circuit board group 106 must be pulled out to the outside. Therefore, it is necessary to previously reserve the extra length of the cables necessary for drawing. Further, a guide mechanism for smoothly pulling out cables is required.
[0005]
As described above, when a printed circuit board is detachably mounted on a connector, a connector (printed circuit board mounting device) configured to detach and mount the printed circuit board in a horizontal direction instead of a vertical direction is disclosed (for example, Patent Document 1). 1). 23 and 24 are perspective views showing the connector, and FIG. 25 is a view schematically showing an electronic device (personal computer) assembled using the connector. As shown in FIGS. 23 and 24, the connector 110 is provided with an opening 112 at one end of a slit 111 on which the printed board 121 is to be mounted. It is configured to be mounted detachably in the horizontal direction. Then, when the terminal portion 122 of the printed circuit board 121 pushes the pushing portion 113 slidably provided on the opposite side of the opening portion 112, one end of the swing portion 114 is pushed by the slope 115 of the pushing portion 113, and the supporting portion is pushed. Rotating around 116, the intermediate portion 117 pushes the pressing plate 118 inward, and the pressing plate 118 pushes the connector terminals arranged on both sides of the slit 111 to make contact with the board terminals of the terminal portions in the slit 111. ing.
[0006]
As shown in FIG. 25, the personal computer 120 assembled using the connector 110 shown in FIGS. 23 and 24 has the connector 110 mounted on the motherboard 119 and the printed circuit board 121 from the open portion 112 of the connector 110. The printed circuit board 121 is mounted on the connector 110 by inserting the terminal portion 122 into the slit 111.
According to the connector 110 as described above, since the printed circuit board 121 is detachably mounted in the horizontal direction, it is possible to improve the problem that the work place is restricted as described above, and to reduce the extra length of cables and the like. The printed circuit board can be attached and detached while the electronic device is operating, without requiring extra work such as setting in advance or providing a guide mechanism for cables and the like.
