Description

【０００１】
【発明の属する技術分野】
本件の発明は，分電バーに接続されるプラグイン端子を備えた複数の分岐ブレーカの一部について，電源を前記分電バー以外から接続する手段に関わり，特に主幹ブレーカと複数の分岐ブレーカを備える分電盤の一部の分岐ブレーカに主幹ブレーカの１次側から電源を供給するための手段に関わる。
【０００２】
分電盤は，主幹ブレーカーの２次側に分岐用銅バーを配し，該分岐用銅バーに複数の分岐ブレーカーを接続し，分岐ブレーカーから負荷機器へ電気を供給する構成となっている。負荷機器として火災報知器などの安全監視機器を接続する場合など，過負荷や漏電などで主幹ブレーカーが切となった場合，電源電圧の供給が停止されるため監視機器が働かなくなり，安全上問題がある。このため，そのような監視機器については主幹ブレーカーの１次側から専用分岐ブレーカーを介して電源を供給（１次送り）するように１次送り配線を行い，主幹ブレーカーが切れても安全監視機器への電源電圧が継続して供給されるようになっている。
【０００３】
【従来の技術】
従来，前述の１次送りの配線は，図１０に示すように，電源側がプラグイン端子構造の分岐ブレーカーを有する分電盤において，分岐用銅バー（分電バー）の一部を１次送り配線用に改変し接続バー１０２１０と１０２２０を配置し，該接続バーの一端に主幹ブレーカー１の１次側端子と接続された１次送り用電線１０２３０と１０２４０を接続し，他端に１次送り専用の分岐ブレーカー１０２００をプラグイン接続するよう配線していた。
【０００４】
【発明が解決しようとする課題】
しかし，１次送り専用分岐ブレーカーを分電盤に配設するにあたり，前記接続バーを設ける必要があるために１次送り専用分岐ブレーカー以外に該１次送り専用分岐ブレーカーと分岐用銅バー（分電バー）を挟んで対峙する分岐ブレーカーを取り外して配線する必要があり，分岐ブレーカーの回路数が減少してしまうという問題があった。
【０００５】
そこで，本件発明は，分電盤内に１次送り分岐ブレーカーを配設する場合に，１次送り専用分岐ブレーカーをその他の２次側の分岐ブレーカーと同一場所に配設でき，なおかつ分岐ブレーカーの回路数を最大限に設けることができる端子台と分電盤を提供することを課題としている。
【０００６】
【課題を解決するための手段】
そこで，本件発明の請求項１は，基板への固定手段とプラグイン端子を有し，該プラグイン端子に導体を接続するための開口を具備し該開口は短側面から長側面に連続して開口しているブレーカのプラグイン端子に電源導体を接続する端子台であって，
該端子台は，主幹ブレーカの１次側と接続する端子部と，前記プラグイン端子に接続され，プラグイン端子の開口のうち，長側面方向の開口長と同程度の幅を有して形成されて，短側面の開口から挿入されて，接続時には長側面方向においては開口内に収納されるバー状端部を備える導電体，該導電体を保持するとともに前記基板への固定手段を備える絶縁枠体から成り，該端子台は，分電盤に設けられる主幹ブレーカの２次側に接続される分電バーに接続するプラグイン端子を含み前記基板に長側面が隣合うように並べて固定される複数の分岐ブレーカを載置する基板の前記複数の分岐ブレーカの側端部に位置する分岐ブレーカへの分電バーからの給電を行わないよう分電バーを予め切断加工したうえで，該側端部に位置する分岐ブレーカの長側面に接して基板に取付けられるとともに，前記導電体のバー状端部はプラグイン端子に挿入接続されて前記ブレーカの長側面側の開口から導出されることを特徴としてブレーカ用端子台を提供したものである。
【０００７】
本件発明の請求項２は，基板と，主幹ブレーカと，主幹ブレーカの２次側に接続される分電バーと，該分電バーに接続するプラグイン端子を含み前記基板に長側面が隣合うように並べて固定される複数の分岐ブレーカを備える分電盤において，前記複数の分岐ブレーカを載置する基板の主幹ブレーカ側の側端部に請求項１記載のブレーカ用端子台を取付けて，主幹ブレーカの１次側端子と該ブレーカ用端子台を接続したことを特徴として１次送りブレーカ付き分電盤を提供したものである。
【０００８】
これにより，本件発明は，分電盤内に１次送り分岐ブレーカーを配設する場合に，１次送り専用分岐ブレーカーをその他の２次側の分岐ブレーカーと同一場所に配設でき，なおかつ分岐ブレーカーの回路数を最大限に設けることができる端子台と分電盤を提供することができる。
【０００９】
【発明の実施の形態】
以下に本件発明を，図面を用いて詳細に説明する。図６から図９は，分岐ブレーカーの電源端子がプラグイン方式で１次送り専用分岐ブレーカーがない分電盤の説明図である。
図６において１は主幹ブレーカー，２と３は分岐ブレーカー配設部であり，複数の分岐ブレーカーが２列に配列され，図では，２側に４個，３側に４個，計８個の分岐ブレーカーを有している。主幹ブレーカーと複数の分岐ブレーカーは，９と４の分電バーにより，主幹ブレーカーの２次側端子１０２と複数の分岐ブレーカーの電源側端子が電気的に接続されている。また，２側と３側の分岐ブレーカーは分電バーを挟んで対峙している。５と６は図の一番左側の上下に位置する分岐ブレーカーの電圧切替装置で５は上側７の分岐ブレーカーの，６は下側８の分岐ブレーカーの電圧切替装置で夫々の分岐ブレーカーへの供給電圧を単相３線式の１００Ｖと２００Ｖに切替えるようになっている。
【００１０】
図７は図６の主幹ブレーカーと分岐ブレーカーと分電バーの部分を詳細に表した図で，図８は１００Ｖ２００Ｖ電圧切替手段を含む分電バーの分解構造を示す。図８において，１１〜１３は主導体で１１は単相３線式のＬ１極，１２はＮ極，１３はＬ２極で，それぞれ主幹ブレーカー１の２次側に接続される。１２のＮ極の主導体からは１２０１のように分岐ブレーカーの数だけＵ字状切欠部が設けられており，１１と１３の主導体には，Ｕ字状切欠部１１０１，１３０１および，接続部１１０２，１３０２が片方の列の分岐ブレーカーの数分だけ設けられている。５０１と６０１は切替ねじ，５０２と６０２は接続板，５０３と６０３は切替接続子，５０４と６０４は雌ねじ部材で，５０１〜５０４と１１０１，１２０１で５の電圧切替装置を，６０１〜６０４，１２０２，１３０１で６の電圧切替装置を構成している。
【００１１】
図９の１０は各電圧切替装置間を絶縁する絶縁枠体で，内部が電圧切替装置の数分の区画に仕切られており，夫々の区画には接続板と主導体の分岐ブレーカーへの接続部を延出する切欠窓部１００１と１００２が設けられている。
【００１２】
図８の電圧切替装置は次のように組み合わせられる。ねじ５０１は接続板５０２の長穴部と切替接続子５０３を貫通し，雌ねじ部材５０４に螺装されるが，雌ねじ部材５０４と切替接続子５０３の間にＵ字状切欠部１１０１または１２０１を挟んで螺着される。１１０１と１２０１のＵ字状切欠部は互いにＵ字の開放部が向かい合わせになるよう配置されており，ねじ５０１を緩めた状態では，ねじ５０１と切替接続子５０３と雌ねじ部材５０４は，接続板５０２の長穴内を移動して，Ｕ字状切欠部１１０１と１２０１の間を行き来できるよう構成されている。
【００１３】
図８において，分電バーと分岐ブレーカーは，絶縁枠体１０から延出した接続板６０２と接続部１１０２に分岐ブレーカー８の電源側プラグイン端子８０１と８０２が差し込まれて弾性的に接続される。この状態でねじ６０１を送り板６０２の長穴内で分岐ブレーカー８に近い位置に寄せてねじを締めつければ，接続板６０２は，Ｎ極に電気的に接続されて，分岐ブレーカー８は単相３線式のＮ極とＬ２極に接続され，１００Ｖの電圧が分岐ブレーカー８に供給され，また長穴内で分岐ブレーカー８から遠い位置に寄せてねじを締めつければ，接続板６０２は，Ｌ１極に電気的に接続されて，分岐ブレーカー８は単相３線式のＬ１極とＬ２極に接続され，２００Ｖの電圧が分岐ブレーカー８に供給されることになる。同様に向かい合って設置される分岐ブレーカー７も電圧切替装置５により供給電圧を切替えることができる。
【００１４】
図１および図２は本件発明のブレーカ用端子台の説明図である。図１において２０はブレーカ，２１は基板，２２は端子台，２３，２４は電源導体である。ブレーカ２０は基板２１に対する取付面に図示しない系合凹部を有し，該系合凹部に基板２１の系合凸起２１１が系合するとともに，基板２１の溝２１２に対し図示しない爪がブレーカ２０から突出して基板２１に固定される。またブレーカ２０の短側面２０１にはプラグイン端子の開口部２０５１，２０６１を有し，該開口は長側面２０２側に連続する開口２０５２，２０６２を有している。
【００１５】
２２は端子台で，該端子台は図２に示すように端子部２２２２と２２３２およびバー状端部２２２１と２２３１を有する導電体２２２と２２３，および絶縁枠体２２１から成り，該絶縁枠体から前記バー状端部２２２１と２２３１および端子部２２２２と２２３２を露出するよう図１のように組み立てられバー状端部２２２１と２２３１はブレーカ２０の短側面２０１のプラグイン端子開口２０５１，２０６１から挿入されてプラグイン端子に接続され，開口２０５２，２０６２に収納されるとともに絶縁枠体は長側面２０２に接して位置し，絶縁枠体の穴２２１１により基板２１の穴２１３にねじ２５で固定される。その後，端子部２２２２，２２３２には電源導体２３，２４が接続され，ブレーカ２０は電源導体２３，２４から電圧を供給される。
【００１６】
図３は，図１に示す端子台２２とブレーカ２０を分電盤に実装する場合の分岐ブレーカと基板および分電バー部の図で，分電バー４および該分電バー４に接続される複数の分岐ブレーカ３１〜３７が基板２１に取り付けられており，分岐ブレーカ３１〜３３の側端部にブレーカ２０と端子台２２が取付られている。なお，導電バー４のブレーカ２０に接続するための接続部は予め切断されている。
【００１７】
図４は，図３に示す分電バーと複数の分岐ブレーカにさらに主幹ブレーカ１を取付け分電盤として構成した概念図で，３１〜３７の分岐ブレーカは主幹ブレーカ１の２次側端子１０２に接続された分電バー４から電圧を供給され，ブレーカ２０のみは端子台２２に接続された電源導体２３，２４を通じ主幹ブレーカ１の１次側端子１０３から電圧を供給するよう構成されている。また図５は図４に示す３４の分岐ブレーカの変わりにブレーカ２０’と端子台２２’を取付け，端子台２２’には主幹ブレーカ１の１次側端子１０３から電圧を供給するようにした場合の実施例である。なお，主幹ブレーカ１の２次側端子１０２から分電バー４までの接続は省略して表してある。このように本件発明によれば，分岐ブレーカの側端部に２個の１次送りブレーカを設置することも可能である。
【００１８】
【発明の効果】
以上によるブレーカ用端子台および１次送りブレーカ付き分電盤によれば，分岐ブレーカ設置部に１次送りブレーカを配設する場合も図１０のように分岐ブレーカの数を犠牲にすることなく図４のように８回路のブレーカ設置スペースがあれば８個のブレーカを設置することが可能なブレーカ端子台および１次送りブレーカ付き分電盤を提供できる。また図５に示すように側端部であれば他のブレーカ３４もまた１次送りブレーカに改変できるという効果がある。
