【発明の属する技術分野】
本発明は、テーブルタップに関するものである。
【０００２】
【従来の技術】
従来のテーブルタップとしては図２４に示すように、幅方向（両側方向）よりも高さ方向が短い略矩形の函体に形成された合成樹脂製の外殻１００を備えて、外郭１００の上面（幅方向の面）に設けた２つのコンセント口１０１には矩形状の栓刃挿入孔１０１ａが１対づつ形成されており、外郭１００の一端からはブッシング１０２を介して電源コード１０３が導入されており、電源コード１０３を介して外部の商用電源から給電される。しかしプラグＰを接続した場合に、上面に接続したプラグＰの出っ張りＸ２によって狭いスペースに設置することができなかった。
【０００３】
そこで、外郭１の高さ方向の面である側面にコンセント口を設けたテーブルタップが提案されていた。（例えば、特許文献１参照。）

【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１５】
本実施形態は、図１〜図４に示すように、合成樹脂製のカバー１０およびボディ２０からなる外殻１を備え、外郭１は幅方向（両側方向）よりも高さ方向が短い略矩形の細長の函体に形成されており、その内部には、プラグの栓刃を受ける３つの刃受けばね３１を各々有する２つの端子板３０ａ，３０ｂと、端子板３０ａ、３０ｂを納装する合成樹脂製の中ボディ４０とが収納されている。そして、外部の商用電源（図示なし）からの電源コード３の端末が、外殻１の一端側に取着したブッシング６０を介して外殻１内部に導入され、端子板３０ａ，３０ｂには電源コード３を介して外部の商用電源から通電される。またカバー１０およびボディ２０の外面には化粧板５が各々取り付けられている。
【００１６】
端子板３０ａ，３０ｂは各々一枚の金属板を折り曲げることで形成され、電源コード３の芯線３ａ，３ａに接続される端子片３２，３２を長手方向の一端側に各々備える。各端子板３０ａ，３０ｂに各々設けた３つの刃受けばね３１は、各々一枚の栓刃を挟み込んで電気的に接触する２つの接触片３１ａからなり、うち２つの刃受けばね３１は各端子板３０ａ，３０ｂの長手方向に沿って外郭１の一方の側面（すなわち高さ方向の面）に向かって配列し、残りの１つの刃受けばね３１は外郭１の他端面（すなわち高さ方向の面）に向かって各端子板３０ａ，３０ｂの長手方向の他端側に配されている。
【００１７】
中ボディ４０は、一面を開口して長辺側と短辺側とを備える略Ｌ字型に形成されており、底面には内部に収められる端子板３０ａ，３０ｂを各々絶縁隔離するための複数の隔離壁４２が形成されている。略Ｌ字型の中ボディ４０の長辺側にはプラグの栓刃が挿入される１対２組の栓刃挿入溝４３が外郭１の一方の側面に向かって形成され、略Ｌ字型の中ボディ４０の短辺側には１対の栓刃挿入溝４３が外郭１の他端面に向かって形成されており、各栓刃挿入溝４３の内側には刃受けばね３１が位置している。
【００１８】
カバー１０およびボディ２０は、各々一面を開口した略矩形の函体に形成され、外殻１は、ボディ２０にカバー１０を各々の周縁部が当接するように取り付け、カバー１０に設けた２つのねじ孔１１を挿通させた組立ねじ６をボディ２０の内底面上に設けた２つの円柱状のリブ２１の軸方向に各々形成したねじ孔２１ａに螺合させることで構成される。
【００１９】
外郭１の一方の側面には、表裏に貫通して後述する受口カバー４１を露出する略矩形の露出孔が２つ形成されるとともに、外郭１の他端面には、表裏に貫通して受口カバー４１を露出する略矩形の露出孔が１つ形成されており、各露出孔の内側には中ボディ４０の栓刃挿入溝４３が一対づつ各々位置している。
【００２０】
受口カバー４１は、裏面の上下辺略中央に各々設けた係止片４１ｂを中ボディ４０の栓刃挿入溝４３の間に位置する切欠部４４に係止させることで、中ボディ４０の栓刃挿入溝４３周辺を覆うように取り付けられる。各受口カバー４１には矩形状の栓刃挿入孔４１ａが１対形成されており、栓刃挿入孔４１ａは中ボディ４０の栓刃挿入溝４３を介して刃受けばね３１に通じている。
【００２１】
図５は本実施形態のテーブルタップの使用状態を示しており、幅方向（両側方向）よりも高さ方向が短い函体に形成された外郭１の高さ方向の面である一方の側面と他端面とにプラグＰの栓刃を挿入する栓刃挿入孔４１ａを設けているので、プラグＰの栓刃を挿入した場合でも高さ方向の長さＸ１を一辺とするスペースがあれば設置でき、狭いスペースでも設置可能となる。
【００２２】
また本実施形態のテーブルタップは、受口カバー４１と中ボディ４０との間に介装された略矩形の扉部５０とさらばね５１とで挿入孔開閉手段を構成している。この扉部５０は、栓刃を栓刃挿入孔４１ａに挿入していないときには栓刃挿入孔４１ａを閉じる位置に移動し、栓刃を栓刃挿入孔４１ａに挿入したときには栓刃挿入孔４１ａを開く位置に移動するものであり、以下、この挿入孔開閉手段について説明する。
【００２３】
図６、図７は受口カバー４１への扉部５０とさらばね５１との取り付けを示しており、受口カバー４１はその裏面に略矩形の凹部４１ｄを形成しており、扉部５０は、凹部４１ｄの底面上に形成した突片４１ｆが扉部５０に穿設した孔５０ｄに挿通した状態で凹部４１ｄ内に収納される。さらばね５１は金属片の両端部５１ａ，５１ａを同方向に折曲した形状を有しており、その両端部５１ａが扉部５１の一端側に当接するように凹部４１ｄの一端側に収納される。
【００２４】
次に図８（ａ）は図７を上面から見た断面図であり、栓刃を栓刃挿入孔４１ａに挿入していないとき扉部５０はさらばね５１の両端部５１ａのばね力によって凹部４１ｄの他端側に移動して、孔５０ｄの一端側が突片４１ｆに係止し、栓刃挿入孔４１ａの内側の開口端は扉部５０によって閉じた状態となる。
【００２５】
図８（ｂ）は栓刃Ｐ１，Ｐ２を栓刃挿入孔４１ａに挿入した時の図である。栓刃Ｐ１，Ｐ２を栓刃挿入孔４１ａに挿入していないとき（図８（ａ）参照）、扉部５０の栓刃挿入孔４１ａに対向する扉部５０の両端部は一端側から他端側に向かって奥に傾斜した傾斜部５０ａ，５０ｅを各々形成して栓刃挿入孔４１ａを閉じている。栓刃Ｐ１，Ｐ２を栓刃挿入孔４１ａに挿入すると栓刃Ｐ１，Ｐ２が傾斜部５０ａ，５０ｅに当接し、傾斜部５０ａ，５０ｅに加えられた栓刃Ｐ１，Ｐ２の押圧力は、扉部５０を押圧力に対して略垂直方向に移動させる力に変換されて、扉部５０はさらばね５１の両端部５１ａのばね力に抗して一端側に移動する。そして、扉部５０の他端側と孔５０ｄの一端側とが栓刃Ｐ１，Ｐ２に各々係止して、栓刃挿入孔４１ａの内側の開口端は開いた状態となり、栓刃挿入孔４１ａに挿入された栓刃Ｐ１は扉部５０の他端側外部を通り、栓刃Ｐ２は孔５０ｄを通り、さらに栓刃挿入溝４３を各々介して、刃受けばね３１ａに挿入される。
【００２６】
栓刃Ｐ１，Ｐ２を引き抜くと、扉部５０はさらばね５１の両端部５１ａのばね力によって凹部４１ｄの他端側に再び移動して、栓刃挿入孔４１ａの内側の開口端を閉じる。このように栓刃Ｐ１，Ｐ２を栓刃挿入孔４１ａに挿入していないときは扉部５０が栓刃挿入孔４１ａの内側開口端を閉じることによって、栓刃挿入孔４１ａから外郭１内へのホコリやゴミの侵入を防止している。
【００２７】
ここで、傾斜部５０ｅのみに栓刃Ｐ２が当接した場合は図８（ａ）の２点鎖線５０’に示すように、扉部５０は上下方向を軸として回転し、扉部５０の表面の他端側に形成された凸部５０ｂが栓刃挿入孔４１ａの内側の一端側を切り欠いたストッパ部４１ｃに係止して、扉部５０の移動が抑制されてプラグＰの挿入を防止する。傾斜部５０ａのみに栓刃Ｐ１が当接した場合も図８（ａ）の２点鎖線５０’’に示すように、扉部５０は上下方向を軸として回転し、扉部５０の表面の一端側に形成された凸部５０ｃが栓刃挿入孔４１ａの内側の一端側を切り欠いたストッパ部４１ｄに係止する。
【００２８】
また図９に示すように、さらばね５１は受口カバー４１の裏面の凹部４１ｄの一端側に収納されており、栓刃Ｐ１，Ｐ２の間には他の金属部品もないため、トラッキング現象による絶縁破壊が起こり難い構造となっている。
【００２９】
次に図４（ａ）、図１０を用いて外郭１へのブッシング６０の取り付けについて説明する。ブッシング６０は外郭１から引き出された電源コード３の外周を覆って内部の芯線３ａの屈曲による断線を防止するもので、その一端側は筒状を成し、他端側は外郭１に固定するための構造を有して、他端側から一端側にかけて滑らかに細くなっている。外殻１の一端側は電源コード３を導入するための開口を形成されており、ブッシング６０はその開口に覆設される。ブッシング６０の他端の両側面には、半円弧状の凸部６３（固定部）が両側方向に突出しており、凸部６３が外郭１の一端側の開口内側の周縁に係止することで外郭１に固定される。
【００３０】
また図１１、図１２に示すように、ブッシング６０の他端側上下部には他端方向に延びた矩形状の弁６１が形成されている。またカバー１０の表面には一端側を開放して形成された凹部１４の一端に凹部１５を設けており、凹部１５の底面上には３つの突起１３が形成されている。そして弁６１は凹部１５に嵌め込まれると共に、弁６１に形成された３つの孔６１ａに突起１３を挿通させて、次にカバー１０の凹部１４，１５に化粧板５が嵌め込まれる。ボディ２０側も同様である。
【００３１】
ここで、ブッシング６０の取り付け部を側面から見た拡大断面である図１３に示すように弁６１は、カバー１０と化粧板５との間、およびボディ２０と化粧板５との間に各々位置しており、電源コード３を上下方向に折り曲げたときに外郭１とブッシング６０との間（Ｓ部）に発生するすきまを弁６１によって隠すことができ、さらに弁６１に形成された３つの孔６１ａに突起１３を挿通して係止させることで、発生するすきまを低減させている。
【００３２】
化粧板５はその両側に各２つづつの計４つの係止片５ａを備え、他端に１つの係止片５ｂを備える。またカバー１０の凹部１４はその両側に各２つの計４つの係止孔１０ａを備え、他端に１つの係止孔１０ｂを備える。そして、係止片５ｂを係止孔１０ｂに係止させた状態で係止片５ａを係止孔１０ａに係止させることで、化粧板５をカバー１０に取り付けることができる。ボディ２０への化粧板５の取り付けも同様である。
【００３３】
上述のように取り付けた化粧板５は、図１４に示すように一端側をブッシング６０、他端側および両側をカバー１０の凹部１４の壁面に囲まれて位置しており、取り外す際は図１５に示すように、化粧板５の一端を臨むブッシング６０の他端に化粧板５の側端を露出させる切り欠き６２を設け、この切り欠き６２にドライバーＤ等を挿入して矢印方向に回転させることによって、簡単に取り外すことができる。ボディ２０からの化粧板５の取り外しも同様である。
【００３４】
また、化粧板５として図１６に示すようにだるま型の孔５ｃを他端側に設けたものを用いてもよい。この場合図１７に示すように、ボディ２の両端方向には両端を開口した溝部２２が形成されて、その一端側にはブッシング６０が前記同様に取り付けられている。溝部２２はその両側の一端側、略中央、他端側に、各３つの計６つの係止孔２０ａを備えており、図１８に示すように化粧板５の両側の一端側、略中央に備えた係止片５ａを、溝部２２の略中央と他端側の係止孔２０ａに各々係止させることで、化粧板５の他端側がボディ２０の外部に突出する。そして孔５ｃを構造物等に設けた突起に掛止させることで、簡易用フックとして利用することができる。
【００３５】
上記実施形態では、外郭１の一方の側面に２つの栓刃挿入孔４１ａを設け、他端面に１つの栓刃挿入孔４１ａを設けた３口のテーブルタップについて説明したが、図１９に示される外郭１の他方の側面側に空いている内部スペースＣを利用して、図２０（ａ）〜（ｄ）に示すように外郭１の他方の側面にも２つの栓刃挿入孔４１ａを設けて５口のテーブルタップを構成したり、あるいは図２１に示すように全ての刃受けばね３１ａへの給電をオン・オフして、全てのコンセント口を一括してオン・オフできるスイッチＳＷ１を設けたり、あるいは図２２に示すようにトラッキング現象の発生時に刃受けばね３１ａへの給電を遮断するトラッキング防止用ブレーカを収容して外郭１の上面にブレーカリセットスイッチＳＷ２を設けたり、あるいは図２３に示すように過電流を検出時に刃受けばね３１ａへの給電を遮断する過電流検知ブレーカを収容して外郭１の上面に過電流検知ブレーカリセットスイッチＳＷ３を設けるとともに、通電電流が５Ａ時に点灯する電流値表示ランプＬａ１、１０Ａ時に点灯する電流値表示ランプＬａ２、１５Ａ時に点灯する電流値表示ランプＬａ３を設けてもよい。
【００３６】
【発明の効果】
請求項１の発明は、幅方向よりも高さ方向が短い外郭と、前記外郭の高さ方向の面に設けられてプラグの複数の栓刃が各々挿入される複数の栓刃挿入孔と、前記外郭に収納されて前記各栓刃挿入孔から内部に挿入された栓刃を受ける刃受けばねを有すると共に外部電源から電線を介して給電される複数の端子板と、前記栓刃挿入孔に挿入される栓刃の押圧力によって前記栓刃挿入孔のいずれかの開口端側に位置する扉部を移動させる挿入孔開閉手段と、前記外郭から引き出された電線の外周を覆って内部の芯線の屈曲による断線を防止するとともに、前記外郭内に固定するための固定部を側面に具備し、さらには前記外郭の外面に係止して取り付けられる面状の弁部を具備するブッシング部とを備え、前記挿入孔開閉手段は、前記栓刃挿入孔に挿入されたプラグの栓刃が当接し、該当接した栓刃の押圧力を前記栓刃挿入孔を開く位置に移動するための力に変換する当接部を有して、１つのプラグに設けた複数の栓刃が各々挿入される前記複数の栓刃挿入孔に対して１つ設けられた扉部と、プラグに設けた複数の栓刃に挟まれない位置に配置されるとともに前記扉部に圧接して、栓刃を前記栓刃挿入孔に挿入していないときに前記扉部を前記複数の栓刃挿入孔を閉じる位置に移動させる力を付勢する金属ばねとから構成され、前記扉部は、栓刃を前記栓刃挿入孔に挿入していないときには前記複数の栓刃挿入孔を閉じる位置にあり、栓刃を前記栓刃挿入孔に挿入したときには前記複数の栓刃挿入孔を開く位置に移動するので、プラグを接続した場合でも狭いスペースに設置できるとともに、プラグを接続していない場合には栓刃挿入孔から内部へのホコリやゴミの侵入を防止することができるという効果がある。また、プラグの栓刃の間に金属ばねがなく、トラッキング現象による絶縁破壊が発生し難いという効果がある。また、ブッシング部の端部に固定部を備えたテーブルタップに比べて、長さを短くすることができ、さらにはブッシング部が曲がったときに外郭とブッシングとの間に発生するすきまを弁によって隠すことができ、さらに弁を外郭の外面に係止させることで発生するすきまを低減させることができるという効果がある。
