【０００１】
【発明の属する技術分野】
本発明は、電気幹線用バスダクトを３方向又は４方向に接続できる垂直分岐用バスダクト接続ユニットに関する。
【０００２】
【従来の技術】
従来、バスダクトを垂直に分岐する方式として、実開昭５５−１０６４２３号のように、（ａ）導体本体の所定位置に長手方向に対して直角に凹溝を設けると共に、分岐導体端部に前記凹溝に合致する切欠部を設け、前記凹溝に分岐導体端部の切欠部を嵌合し、その接触面をはんだ付けして接続するものがある。
【０００３】
また、特公昭５１−１５５９２号のように、（ｂ）バスダクトの中間分岐部の導体にＶ字切欠部を設け、このＶ字切欠部にボルト挿通溝を設け、前記導体の中間分岐部側面と分岐するためのプラグインブレーカの分岐導体端部側面とを導電性接続板を介して電気的に接触させ、ボルトで一括緊締するものがある。
【０００４】
【発明が解決しようとする課題】
しかし、上記バスダクトの垂直分岐方式の（ａ）の場合には、半田付けの作業や半田付け部の仕上げ作業が必要となり、非常な労力を要する。また、（ｂ）の場合には、バスダクトの導体の略中間部で分岐を行っており、垂直分岐用のバスダクトが長くなることから、組立、運搬、施工等の作業性が非常に悪いという不具合を生じている。
【０００５】
本発明は上記不具合を解消するためのなされたものであって、構造が簡単で取扱いが容易な垂直分岐用バスダクト接続ユニットを提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
本発明の垂直分岐用バスダクト接続ユニットは、対向配置された基準バスダクトと、該基準バスダクトの導体幅方向から該基準バスダクト相互間の略中心に向けられ、その導体が該基準バスダクトの導体と略同一面内になるように配置された分岐バスダクトとを接続する垂直分岐用バスダクト接続ユニットであって、該接続ユニットが、挿入される該基準バスダクト及び該分岐バスダクトの同相の導体端部に接触可能に配置された導電性接続部材と、挿入される該基準バスダクト及び該分岐バスダクトの最外側の導体端部を外方から収納するダクト側板継ぎ板と、挿入される該基準バスダクト及び該分岐バスダクトの異相の導体端部間及び該最外側の導体端部と該ダクト側板継ぎ板との間に配置される絶縁セパレータと、挿入される該基準バスダクト及び該分岐バスダクトの導体端部、該導電性接続部材、該ダクト側板継ぎ板、該絶縁セパレータを一括緊締することが可能な締着具とを備えることを特徴とする。前記垂直分岐用バスダクト接続ユニットは、例えば一直線状に対向配置された接続すべき２本の基準バスダクトを接続し、更に対向配置された基準バスダクト相互間の中心部に対して垂直に配置された分岐バスダクトを分岐接続するものである。
【０００７】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記導電性接続部材と前記絶縁セパレータと前記ダクト側板継ぎ板の対応箇所にそれぞれ貫通孔が設けられ、該貫通孔に締着具が挿通されて一括仮締着されていることを特徴とする。前記構成により、前記接続ユニットを締着具で予め一括仮締着しておくことができる。
【０００８】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記接続ユニットが、前記基準バスダクトの導体端部間を接続する主接続部と、前記主接続部と前記分岐バスダクトの導体端部間を接続する分岐接続部とを有し、前記締着具として、該主接続部を緊締する基準締着具と、該分岐接続部を緊締する分岐締着具とを設けたことを特徴とする。
【０００９】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記接続ユニットが、前記基準バスダクトの導体端部間を接続する主接続部と、前記主接続部と前記分岐バスダクトの導体端部間を接続する分岐接続部とを有し、前記絶縁セパレータとして、該主接続部に配置される基準絶縁セパレータと、該分岐接続部に配置される分岐絶縁セパレータとを設けたことを特徴とする。また、本発明の垂直分岐用バスダクト接続ユニットは、前記主接続部と前記分岐接続部のダクト側板継ぎ板が連続して一体形成されていることを特徴とする。
【００１０】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記接続ユニットが、対向する一方の前記基準バスダクトの導体端部と前記分岐バスダクトの導体端部を接続する第１接続部と、対向する他方の前記基準バスダクトの導体端部と前記分岐バスダクトの導体端部を接続する第２接続部とを有し、前記締着具として、該第１接続部を緊締する第１締着具と、該第２接続部を緊締する第２締着具とを設けたことを特徴とする。また、本発明の垂直分岐用バスダクト接続ユニットは、対向配置された基準バスダクトと、該基準バスダクトの導体幅方向から該基準バスダクト相互間の略中心に向けられ、その導体が該基準バスダクトの導体と略同一面内になるように配置された分岐バスダクトとを接続する垂直分岐用バスダクト接続ユニットであって、該接続ユニットが、挿入される該基準バスダクト及び該分岐バスダクトの同相の導体端部に接触可能に配置された導電性接続部材と、挿入される該基準バスダクト及び該分岐バスダクトの最外側の導体端部を外方から収納するダクト側板継ぎ板と、挿入される該基準バスダクト及び該分岐バスダクトの異相の導体端部間及び該最外側の導体端部と該ダクト側板継ぎ板との間に配置される絶縁セパレータと、挿入される該基準バスダクト及び該分岐バスダクトの導体端部、該導電性接続部材、該ダクト側板継ぎ板、該絶縁セパレータを一括緊締することが可能な締着具とを備えると共に、該基準バスダクトの長手方向に離間した状態で配置される、該締着具である第１締着具を有する第１接続部と、該締着具である第２締着具を有する第２接続部とを有し、該第１接続部と該第２接続部のダクト側板継ぎ板が一体に形成されていることを特徴とする。
【００１１】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記分岐バスダクトの導体端部が、対向する前記基準バスダクトの導体端部間に配置される構成であることを特徴とする。
【００１２】
さらに、本発明の垂直分岐用バスダクト接続ユニットは、上記接続ユニットに於いて、前記基準バスダクトの導体幅方向の両側に対向配置された分岐バスダクトを接続可能に構成されていることを特徴とする。例えば直線状に対向配置する２本の基準バスダクト相互間の中心部を中心にして、基準バスダクトの垂直方向である導体幅方向の両側に２本の分岐バスダクトを対向させ、分岐バスダクトの導体と基準バスダクトの導体が同一平面内になるように配置し、上記接続ユニットに各基準バスダクトの導体端部及び各分岐バスダクトの導体端部を挿入して接続を行う。
【００１３】
【作用】
本発明の垂直分岐用バスダクト接続ユニットは、基準バスダクトの導体端部及び分岐バスダクトの導体端部を接続ユニットに挿入嵌着するだけで分岐を可能にする構成であるため、施工時の分岐の作業性が向上する。また、バスダクトの接続とバスダクトの垂直分岐を同時に行うことが可能で、一体型の垂直分岐用バスダクトを製造する必要がなくなり、コストダウンに繋がる。
【００１４】
また、基準バスダクトと分岐バスダクトを接続する前は、本発明の垂直分岐用バスダクト接続ユニットを締着具で仮止めした状態にしておくことで、持ち運び或いは接続作業時に分解することがなくなり、持ち運び及び接続作業を容易に行うことが可能となる。
【００１５】
また、それぞれ基準バスダクトの導体端部間を接続する主接続部と、該主接続部と分岐バスダクトの導体端部を接続する分岐接続部を設け、それぞれ基準締着具、分岐締着具で緊締する構成とすることにより、接続すべき基準バスダクト及び分岐バスダクトを強固に接続することが可能となる。
【００１６】
また、主接続部及び分岐接続部にそれぞれ別体の基準絶縁セパレータ、分岐絶縁セパレータを設けることにより、通常のバスダクトの直線接続に用いられる絶縁セパレータを基準絶縁セパレータや分岐絶縁セパレータとしてそのまま用いることが可能となって、新たに垂直分岐用の絶縁セパレータを製造する必要がなくなり、コストダウンに繋がる。
【００１７】
また、本発明の別の垂直分岐用バスダクト接続ユニットは、２本の基準バスダクトの何れか一方の導体端部と前記分岐バスダクトの導体端部とを接続する第１接続部と、他方の基準バスダクトの導体端部と分岐バスダクトの導体端部とを接続する第２接続部とを有し、それぞれ第１締着具、第２締着具で緊締する構成とすることにより、接続すべき基準バスダクト及び分岐バスダクトを強固に接続することが可能となる。
【００１８】
また、分岐用バスダクトの導体端部を２本の基準バスダクトの導体端部間に配置することにより、接続強度をより増加させることができる。
【００１９】
また、本発明の垂直分岐用バスダクト接続ユニットを２本の分岐バスダクトを接続可能に構成し、基準バスダクトに対して上下（又は左右）の２方向に分岐を可能にしても好適である。
【００２０】
【発明の実施の形態】
以下、本発明の垂直分岐用バスダクト接続ユニットの実施例について図面に基づき説明する。図１から図４までは、本発明の垂直分岐用バスダクト接続ユニットの第１実施例について示し、図１は垂直分岐用バスダクト接続ユニットの非接続状態を示す正面図、図２は前記接続ユニットの接続状態を示す正面図、図３は図１の側面説明図、図４は図２の側面説明図である。
【００２１】
垂直分岐用バスダクト接続ユニット１０は、図１及び図３に示すように、２本の基準バスダクト２０・２０と１本の分岐バスダクト３０とを接続するものである。基準バスダクト２０と分岐バスダクト３０は、それぞれ絶縁物で被覆された三線の導体２１、３１がダクト側板２２・２２間又はダクト側板３２・３２間に収納され、導体２１、３１の先端である導体端部２１ａ、３１ａは絶縁物の被覆が無く露出している構成である。前記２本の基準バスダクト２０・２０は対向して、垂直分岐用バスダクト接続ユニット１０の左右両側にそれぞれ配置され、分岐バスダクト３０は、基準バスダクト２０の長手方向と垂直で接続ユニット１０の上方に配置されている。
【００２２】
垂直分岐用バスダクト接続ユニット１０は、２枚のダクト側板継ぎ板１１を備え、前記２枚のダクト側板継ぎ板１１・１１の間に、接続するバスダクト２０、３０の異相の導体端部２１ａ・２１ａ間若しくは３１ａ・３１ａ間、及び最外側の導体端部２１ａ、３１ａとダクト側板継ぎ板１１間の絶縁を行うための４枚の絶縁セパレータ１２が設けられている。前記絶縁セパレータ１２・１２間には、絶縁セパレータ１２に沿ってそれぞれ２枚の導電性接続部材１３・１３が設けられており、接続する対向配置された基準バスダクト２０・２０の導体端部２１ａ・２１ａ及び接続する分岐バスダクト３０の導体端部３１ａが導電性接続部材１３・１３間に挿入嵌合された際に、各導体端部２１ａ、３１ａは導電性接続部材１３・１３間で狭持され電気的に接続されるようになっている。
【００２３】
ダクト側板継ぎ板１１、絶縁セパレータ１２、導電性接続部材１３には、図に省略した締着具を挿通するための貫通孔が形成されており、締着具１４である絶縁スリーブ付きのボルト１４ａが、一方のダクト側板継ぎ板１１の外方から座金１４ｃを介して前記貫通孔に挿通され、他方のダクト側板継ぎ板１１の外方から座金１４ｃを介して前記ボルト１４ａにナット１４ｂが螺合され、接続ユニット１０は一括して仮締着されている。接続ユニット１０が前記締着具１４で一括して仮締着されていることにより、接続ユニット１０の持ち運び時、或いは基準バスダクト２０及び分岐バスダクト３０に対する接続作業時に分解することがなく、容易に持ち運び及び接続作業を行うことが可能となる。
【００２４】
ダクト側板継ぎ板１１の外側面の略中央には、位置決め凸部１５が設けられ、位置決め凸部１５は弾性を有し、座金１４ｃよりも幅狭に形成され、且つ位置決め凸部１５の上端が座金１４ｃの上端よりも下に位置するように構成されており、前記位置決め凸部１５は接続ユニット１０が仮締着された状態で、ダクト側板継ぎ板１１と座金１４ｃとの間に位置する。前記位置決め凸部１５は、基準バスダクト２０の接続位置の決定に役立つと共に、バスダクト２０、３０の機械的接続強度を向上することができる。
【００２５】
尚、ダクト側板継ぎ板１１、絶縁セパレータ１２、導電性接続部材１３は、接続するバスダクト２０、３０を接続した状態であるＴ字形に合わせて略Ｔ字形に形成されており、接続状態で優れた外観となるように構成されている。
【００２６】
前記垂直分岐用バスダクト接続ユニット１０で基準バスダクト２０・２０及び分岐バスダクト３０を接続する場合には、図２及び図４に示すように、基準バスダクト２０のダクト側板２２が、垂直分岐用バスダクト接続ユニット１０のダクト側板継ぎ板１１の外方に位置するように、且つ位置決め凸部１５に当接するまで、対向する基準バスダクト２０・２０を接続ユニット１０に挿入する。その後、分岐バスダクト３０も同様に、ダクト側板３２が接続ユニット１０のダクト側板継ぎ板１１の外方に位置するように、且つ基準バスダクト２０のダクト側板２２に当接するまで接続ユニット１０に挿入する。
【００２７】
前記のように基準バスダクト２０・２０及び分岐バスダクト３０を最適位置まで接続ユニット１０に挿入することにより、接続するバスダクト２０、３０の導体端部２１ａ、３１ａが導電性接続部材１３・１３間に所定寸法挿入されて良好な電気的接続を確保することができ、また、バスダクト２０、３０の良好な機械的接続強度を確保することができるように構成されている。そして、バスダクト２０、３０を接続ユニット１０に挿入し終えた後には、ナット１４ｂを緊締して締着具１４で一括して本締着し、良好な電気的接続性及び機械的接続強度を確保することができる前記最適位置で、バスダクト２０、３０を接続ユニット１０を介して接続することができる。
【００２８】
締着具１４で本締着した際に、接続ユニット１０のダクト側板継ぎ板１１と座金１４ｃとの間の位置決め凸部１５は弾性を有することから、位置決め凸部１５の左右にそれぞれ配置された基準バスダクト２０・２０のダクト側板２２・２２と、位置決め凸部１５の上方に配置された分岐バスダクト３０のダクト側板３２は、ダクト側板継ぎ板１１と座金１４ｃで強固に狭持されて接続されることとなる。
【００２９】
そして、前記本締着でバスダクト２０、３０を接続ユニット１０を介して接続した後、接続箇所に於ける粉塵等の入り込みを防止するため、垂直分岐用バスダクト接続ユニット１０の対応開口部に、断面略コ字形で略長方形平板状のカバー部材４０ａと、断面略コ字形で略Ｌ字形平板状のカバー部材４０ｂとをそれぞれ配設し、カバー部材４０ａ、４０ｂをビス等で接続ユニット１０或いはバスダクト２０、３０に固定し、最終的な接続作業が終了する。尚、カバー部材４０ａ、４０ｂで接続するバスダクト２０・２０間又はバスダクト２０・３０間のケースアースを接続するように構成すると、新たにアース線を必要としなくなり、より安価に垂直分岐用バスダクト接続ユニット１０を提供することができる。
【００３０】
次に、本発明の垂直分岐用バスダクト接続ユニットの第２実施例について、上記第１実施例と構成が異なる箇所を中心に説明する。図５から図１０までは本発明の第２実施例を示し、図５は垂直分岐用バスダクト接続ユニットの非接続状態を示す正面図、図６は前記接続ユニットの接続状態を示す正面図、図７は前記接続ユニットの分解側面図、図８は図５の側面説明図、図９は図６の側面説明図、図１０は第２実施例の導電性接続部材の斜視図である。
【００３１】
垂直分岐用バスダクト接続ユニット１０１は、図５から図９に示すように、基準バスダクト２０・２０を接続するための主接続部１０１ａと、主接続部１０１ａと分岐バスダクト３０を接続するための分岐接続部１０１ｂとで構成され、主接続部１０１ａと分岐接続部１０１ｂのダクト側板継ぎ板１１１及び導電性接続部材１３１はそれぞれ連続して略Ｔ字形に一体形成されている。尚、導電性接続部材１３１やダクト側板継ぎ板１１１は、接続するバスダクト２０、３０を接続した状態である略Ｔ字形に形成されているため、外観に優れている。
【００３２】
主接続部１０１ａは、接続する基準バスダクト２０の導体端部２１ａ・２１ａ間及び最外側の導体端部２１ａとダクト側板継ぎ板１１１間を絶縁するための基準絶縁セパレータ１２１ａと、基準バスダクト２０の導体端部２１ａ、導電性接続部材１３１、基準絶縁セパレータ１２１ａ、ダクト側板継ぎ板１１１を一括緊締するための基準締着具１４１ａを備える。また、分岐接続部１０１ｂは、接続する分岐バスダクト３０の導体端部３１ａ・３１ａ間及び最外側の導体端部３１ａとダクト側板継ぎ板１１１間を絶縁するための分岐絶縁セパレータ１２１ｂと、分岐バスダクト３０の導体端部３１ａ、導電性接続部材１３１、分岐絶縁セパレータ１２１ｂ、ダクト側板継ぎ板１１１を一括緊締するための分岐締着具１４１ｂを備える。
【００３３】
各相の導電性接続部材１３１は、図５から図１０に示すように、２枚の導線性接続部材１３１ｍ、１３１ｎにより形成され、各導電性接続部材１３１ｍ、１３１ｎには締着具１４１ａ、１４１ｂのボルト１４ｃを挿通するための貫通孔１３１ｏが設けられている。また、基準絶縁セパレータ１２１ａと分岐絶縁セパレータ１２１ｂとの間に位置する部分には段差部１３１ｐが形成され、段差部１３１ｐ・１３１ｐ間の導電性接続部材１３１ｍ、１３１ｎは隣接した状態となっており、前記隣接箇所は絶縁物１３１ｑで被覆されている。
【００３４】
前記ダクト側板継ぎ板１１１には、主接続部１０１ａの略中央に、接続される基準バスダクト２０の導体幅方向を長手方向とする略長方形の位置決め凸部１５１ａが設けられ、同様に分岐接続部１０１ｂの略中央に、接続される分岐バスダクト３０の導体幅方向を長手方向とする略長方形の位置決め凸部１５１ｂが設けられている。
【００３５】
第２実施例の接続ユニット１０１による基準バスダクト２０・２０の接続に関しては、第１実施例の場合と同様であり、主接続部１０１ａに於ける導電性接続部材１３１ｍ・１３１ｎ間に導体端部２１ａを挿入する等により接続する。また、分岐バスダクト３０を接続する際には、導体端部３１ａを分岐接続部１０１ｂに於ける導電性接続部材１３１ｍ・１３１ｎ間に挿入しながら、ダクト側板３２の先端が分岐接続部１０１ｂの略中央に配設された位置決め凸部１５１ｂに当接するまで分岐バスダクト３０を分岐接続部１０１ｂに挿入し、前記挿入後に分岐締着具１４１ｂで一括緊締して接続する。
【００３６】
尚、分岐接続部１０１ｂの導電性接続部材１３１ｍ・１３１ｎ間で、接続する分岐バスダクト３０の導体端部３１ａ等が挿入されない箇所には、予め導体間座部材１６１を填め込んでおくことにより、接続ユニット１０１のダクト側板継ぎ板１１１が分岐締着具１４１ｂ等の締付で変形することを防止できる。また、同様に分岐接続部１０１ｂに於けるダクト側板継ぎ板１１１で、分岐バスダクト３０のダクト側板３２が外側に接触しない箇所には、予め側板間座部材１６２を填め込んでおくことにより、分岐締着具１４１ｂ等の緊締強度をより向上することができる。
【００３７】
第２実施例では主接続部１０１ａに対する基準締着具１４１ａと、分岐接続部１０１ｂに対する分岐締着具１４１ｂとをそれぞれ別個に設けているため、接続ユニット１０１とバスダクト２０、３０との接続をより強固に行うことが可能となる。また、同様に主接続部１０１ａの基準絶縁セパレータ１２１ａと分岐接続部１０１ｂの分岐絶縁セパレータ１２１ｂも別個に設けているため、これらに通常のバスダクトの直線接続時で使用する接続ユニットの絶縁セパレータをそのまま使用することが可能となり、新たに垂直分岐用の絶縁セパレータを別途製造する必要がなく、コストダウンに繋がる。
【００３８】
次に、本発明の垂直分岐用バスダクト接続ユニットの第３実施例について、上記第１、２実施例と構成が異なる箇所を中心に説明する。図１１から図１４までは本発明の第３実施例を示し、図１１は垂直分岐用バスダクト接続ユニットの非接続状態を示す正面図、図１２は前記接続ユニットの接続状態を示す正面図、図１３は図１１の底面説明図、図１４は図１２の底面説明図である。
【００３９】
本実施例の垂直分岐用バスダクト接続ユニット１０２は、図１１から図１４に示すように、左右に長く形成された略長方形であって、一方の基準バスダクト２０と分岐バスダクト３０とを接続する第１接続部１０２ａと、他方の基準バスダクト２０と分岐バスダクト３０とを接続する第２接続部１０２ｂとで構成されており、それぞれ左右に第１締着具１４２ａ、第２締着具１４２ｂが設けられ、ダクト側板継ぎ板１１２、絶縁セパレータ１２２、導電性接続部材１３２が第１締着具１４２ａ及び第２締着具１４２ｂで仮締着されている。
【００４０】
前記接続ユニット１０２の左右に長く形成されている外形に対応して、ダクト側板継ぎ板１１２、絶縁セパレータ１２２、導電性接続部材１３２は左右に長く形成された略長方形平板状に形成されている。また、ダクト側板継ぎ板１１２には、基準バスダクト２０の導体幅方向を長手方向とする略長方形の位置決め凸部１５２ａ、１５２ｂが、ダクト側板継ぎ板１１２の左右対称に２箇所、それぞれ第１締着具１４２ａ、第２締着具１４２ｂの略中央に設けられ、分岐バスダクト３０の導体幅方向を長手方向とする略長方形の位置決め凸部１５２ｃが、ダクト側板継ぎ板１１２の略下方中央位置に１箇所設けられており、バスダクト２０、３０を接続ユニット１０２に接続するときの接続位置を決定するのに役立つようになっている。
【００４１】
位置決め凸部１５２ａ、１５２ｂ相互の配置間隔は、前記相互間に分岐バスダクト３０のダクト側板３２が挿入可能なように、少なくともダクト側板３２の幅方向の長さよりも長くなっており、接続ユニット１０２に挿入される基準バスダクト２０・２０の導体端部２１ａ・２１ａの間に、分岐バスダクト３０の導体端部３１ａを挿入して接続するようになっている。また位置決め凸部１５２ｃは、位置決め凸部１５２ｃまで分岐バスダクト３０のダクト側板３２を挿入した場合に、接続ユニット１０２内の導電性接続部材１３２の下端の厚み面と、分岐バスダクト３０の導体長手方向の最先端にある導体端部３１ａの厚み面とが略同一面上になるようにし、分岐バスダクト３０の導体端部３１ａと導電性接続部材１３２の接触面積をできる限り大きくするように構成している。
【００４２】
