【発明の属する技術分野】
本発明は、コンセントに関するものである。
【０００２】
【従来の技術】
壁面等に埋め込み配設するコンセントとして、平型栓刃と丸ピン型栓刃の両方を接続することができるコンセントが従来提供されている（特許文献１）
ところで、この種のコンセントには、図８に示すように器体１を構成するボディ１Ａとカバー１Ｂにおいて、ボディ１Ａ内に設けられた収納室２、２を仕切る仕切壁３Ａの端面に凸部４を一体形成し、この凸部４により収納室２、２に収納される刃受け部材５、５間の絶縁距離を長く取るものがあった。
【０００３】
この場合、更に絶縁性能を高めるためにボディ１Ａに被着するカバー１Ｂ側の仕切壁３Ｂには上記凸部４が嵌め込まれる凹部６を形成していた。
【０００４】
またボディ１Ａの上記収納室２に刃受け部材５とともに収納される電線接続用の速結端子装置の端子板７は図９（ａ）（ｂ）に示すように平板状に形成され、仕切壁３Ａに沿って配置されていた
また、上記の特許文献１に記載のコンセントは図１０、図１１に示すようにカバー１Ｂ内に、カバー１Ｂの天井部（前面壁）の両側に開口した栓刃挿入口７、７を両端部で塞ぐように配置された一対の扉体９、９と、両扉体９、９の各中央部９０を両扉体９、９を対向する方向に弾性付勢するばね体（図示せず）と、両扉体９、９及び前記ばね体を支持する中枠（図示せず）とからなる栓刃挿入口閉鎖手段を備え、栓刃挿入時以外は充電部が栓刃挿入口７、７から露出しないようにしていた。

【発明が解決しようとする課題】
ところで、上述のように絶縁性能を良くするためにボディ１Ａの仕切壁３Ａに凸部４を、またカバー１Ｂの仕切壁３Ｂに凹部６を形成しているコンセントでは、部品寸法ばらつきの許容範囲を大きくすると、凹部６とこの凹部６に嵌る凸部４との間に隙間ができ、栓刃と刃受け部材５との接触時に発生する金属粉（切粉）が上記隙間に入り込む恐れがあった。
【０００７】
そして壁面等に埋め込み配設されるコンセントの場合、凹部６が垂直方向に配置されるため、上記のような上記隙間に金属粉が入り込めば、凹部６の下端６ａに溜まり、絶縁破壊の経路になる可能性があった。
【０００８】
一方、上述のような端子板８の配置では、仕切壁３Ａを挟んで背中合わせに配置される端子板８、８同士の距離が短いため、上述のように凹部６の下端６ａに金属粉が溜まる場合、短絡経路が形成され易かった。
【０００９】
更に丸ピン型栓刃と平型栓刃とに対応するコンセントでは、カバー１Ｂに設けられる栓刃挿入口７は平型栓刃挿入口７ａと、仕切壁とは反対側位置において平型栓刃挿入口７ａの一側縁に連通した丸ピン型栓刃挿入口７ｂとから形成されているが、カバー１Ｂ内に栓刃挿入口閉鎖手段を設けている場合、平型栓刃挿入口７ａから挿入される栓刃の押入力を受けて各扉体９に反対向方向に移動させる力を与える栓刃受け斜面１０ａに臨む前記中央部９０の垂立面９０ａが平型栓刃挿入口７ａの内壁面付近に位置するため、部品寸法ばらつきによっては、両扉体９、９の中央部９０、９０の突き合わせ部位の隙間９０ｂが図１１に示すように平型栓刃挿入口７ａを介して図１０に示すように外部から見え、そのため比較的容易に隙間９ｂに鋭利な物を差し込むことができ、例えば隙間９０ｂに鋭利な物を引っ掛けて扉体９を開く方向に力を加えた場合、開いてしまうことがあった。
【００１０】
尚栓刃受け斜面１０ａ及び丸ピン型栓刃の押入力を受ける栓刃受け斜面１０ｂを設けている扉体９、９の端部での突き合わせ部位の隙間に物を差し込んだときには扉体９、９は中枠に支持されている支点部９１を中心に当該端部を図において下方へ移動させるように回転し、中枠等に設けたロック片に下方移動側の端部が引っ掛かったり、或いは反対側の端部がカバー１Ｂに引っ掛かることで扉体９、９が開く方向に動かないようなっている。
【００１１】
本発明は、上述の点に鑑みて為されたもので、その目的とするところは部材寸法のばらつきによって器体内へ異物が入り易くなった場合にも、電気的な安全面におけるトラブル発生を防ぐことができるコンセントを提供することにある。
【００１２】
【課題を解決するための手段】
上述の目的を達成するために、請求項１の発明では、一面開口の箱型であって、内部が底部から立ち上がった第１の仕切壁により長手方向に２分され、該仕切壁の両側に刃受け部材を含む充電部位を収納する収納室が設けられたボディと、該ボディの開口側に被着される面側が開口された箱型であって、内部が天井部から垂下した第２の仕切壁により長手方向に２分されるとともに、被着時に前記ボディ側の前記各収納室内の刃受け部材に対向する天井部に栓刃挿入口を開口しているカバーとから器体が構成されたコンセントにおいて、前記第１の仕切壁の端面に凸部を、前記第２の仕切壁に前記凸部が嵌り込む凹部を夫々形成するとともに、前記凸部及び凹部の両端方向の長さを両端が前記器体の両側の外側面に至る長さに形成していることを特徴とする。

【００１５】
請求項２の発明によれば、凸部によりボディの両側の収納部内の充電部位間の絶縁距離を長くすることができるとともに、凸部を嵌め込む凹部により絶縁性能を更に向上でき、また壁面等に配設して凹部の一端部が下端側になり、しかも部品寸法のばらつきにより生じた凸部と凹部の間に隙間に、刃受け部材に対する栓刃の挿脱の際に生じる金属粉が入って上記下端側に落下してきても、下端側に位置する両側の収納部内の端子板の端部間の距離が長く取れているため、金属粉による短絡経路が形成しにくく、電気的な安全面におけるトラブル発生を防げる。
【００１６】
請求項３の発明では、一面開口の箱型であって、内部が底部から立ち上がった第１の仕切壁により長手方向に２分され、該仕切壁の両側に刃受け部材を含む充電部位を収納する収納室が設けられたボディと、該ボディの開口側に被着される面側が開口された箱型であって、内部が天井部から垂下した第２の仕切壁により長手方向に２分されるとともに、被着時に前記ボディ側の前記各収納室内の刃受け部材に対向する天井部に栓刃挿入口を開口しているカバーとから器体が構成されたコンセントにおいて、前記第１の仕切壁の端面に凸部を、前記第２の仕切壁に前記凸部が嵌り込む凹部を夫々形成するとともに、前記凸部及び凹部の両端方向の長さを両端が前記器体の両側の外側面に至る長さに形成し、前記各収納部内で上記第１の仕切壁に壁面に沿うように配置される端子装置の端子板の両側端を第１の仕切壁の壁面から離れる方向に形成していることを特徴とする。
【００１７】
請求項３の発明によれば、凸部によりボディの両側の収納部内の充電部位間の絶縁距離を長くすることができるとともに、凸部を嵌め込む凹部により絶縁性能を更に向上でき、また壁面等に配設して凹部の一端部が下端側になり、しかも部品寸法のばらつきにより生じた凸部と凹部の間に隙間に、刃受け部材に対する栓刃の挿脱の際に生じる金属粉が入って上記下端側に落下してきても凹部の下端から金属粉を排出することができ、その上下端側に位置する両側の収納部内の端子板の端部間の距離が長く取れているため、金属粉による短絡経路が形成しにくく、電気的な安全面におけるトラブル発生をより確実に防げる。
【００１８】
請求項４の発明では、一面開口の箱型であって、内部が底部から立ち上がった第１の仕切壁により長手方向に２分され、該仕切壁の両側に刃受け部材を含む充電部位を収納する収納室が設けられたボディと、該ボディの開口部側に被着する面が開口された箱型であって、内部が天井部から垂下した第２の仕切壁により長手方向に２分されるとともに、被着時に前記ボディ側の前記各収納室内の刃受け部材に対向する天井部に栓刃挿入口を開口しているカバーとから器体が構成されたコンセントにおいて、前記刃受け部材が平型栓刃の刃受け部位と丸ピン型栓刃の刃受け部位を備えた刃受け部材であり、前記栓刃挿入口が前記第２の仕切壁に並行する方向に形成した平型栓刃挿入口と、前記第２の仕切壁とは反対側位置において前記平型栓刃挿入口の一側縁に連通した丸ピン型栓刃挿入口とから形成され、前記カバー内には、両側の前記栓刃挿入口を並行する両端部で塞ぐように配置された一対の扉体と、両扉体を対向する方向に弾性付勢するばね体と、両扉体及びばね体を支持する中枠とからなる栓刃挿入口閉鎖手段を備え、前記一対の扉体の両端部には、対応する前記栓刃挿入口の平型栓刃挿入口及び丸ピン型栓刃挿入口に夫々対向する部位に夫々の栓刃挿入口から挿入される栓刃の押入力を受けて各扉体に反対向方向に移動させる力を与える栓刃受け斜面を形成し、各扉体の中央部には上記中枠に両端方向に揺動自在に支持される支点部を形成し、前記平型栓刃挿入口に対応する前記栓刃受け斜面側に臨む前記中央部の垂立面の位置を、平型栓刃挿入口の内壁面より離れたカバーの天井部の下側位置として成ることを特徴とする。
【００１９】
請求項４の発明によれば、多少の部品寸法ばらつきがあっても、平型栓刃挿入口に対応する前記栓刃受け斜面側に臨む両扉体の中央部の突き合わせ部位の隙間が平型栓刃挿入口を介して外部から見えず、子供の悪戯などで隙間に物が差し込まれるのを防ぐことができ、電気的な安全面におけるトラブル発生を防げる。
【００２０】
請求項５の発明では、請求項４の発明において、前記第１の仕切壁の端面に凸部を、前記第２の仕切壁に前記凸部が嵌り込む凹部を夫々形成するとともに、前記凸部及び凹部の両端方向の長さを両端が前記器体の両側の外側面に至る長さに形成していることを特徴とする。
【００２１】
請求項５の発明によれば、多少の部品寸法ばらつきがあっても、平型栓刃挿入口に対応する前記栓刃受け斜面側に臨む両扉体の中央部の突き合わせ部位の隙間が平型栓刃挿入口を介して外部から見えず、子供の悪戯などで隙間に物が差し込まれるのを防ぐことができる上に、凸部によりボディの両側の収納部内の充電部位間の絶縁距離を長くすることができるとともに、凸部を嵌め込む凹部により絶縁性能を更に向上でき、また壁面等に配設して凹部の一端部が下端側になり、しかも部品寸法のばらつきにより生じた凸部と凹部の間に隙間に、刃受け部材に対する栓刃の挿脱の際に生じる金属粉が入って上記下端側に落下してきても凹部の下端から金属粉を排出することができ、金属粉の溜まりによる短絡経路の形成を防止でき、電気的な安全面におけるトラブル発生を防げる。
【００２２】
請求項６の発明では、請求項５の発明において、前記各収納部内で上記第１の仕切壁に壁面に沿うように配置される端子装置の端子板の両側端を第１の仕切壁の壁面から離れる方向に形成していることを特徴とする。
【００２３】
請求項６の発明によれば、多少の部品寸法ばらつきがあっても、平型栓刃挿入口に対応する前記栓刃受け斜面側に臨む両扉体の中央部の突き合わせ部位の隙間が平型栓刃挿入口を介して外部から見えず、子供の悪戯などで隙間に物が差し込まれるのを防ぐことができる上に、凸部によりボディの両側の収納部内の充電部位間の絶縁距離を長くすることができるとともに、凸部を嵌め込む凹部により絶縁性能を更に向上でき、また壁面等に配設して凹部の一端部が下端側になり、しかも部品寸法のばらつきにより生じた凸部と凹部の間に隙間に、刃受け部材に対する栓刃の挿脱の際に生じる金属粉が入って上記下端側に落下してきても凹部の下端から金属粉を排出することができ、金属粉の溜まりによる短絡経路の形成を防止でき、更に端側に位置する両側の収納部内の端子板の端部間の距離が長く取れているため、金属粉による短絡経路が形成しにくく、電気的な安全面におけるトラブル発生をより確実に防げる。
【００２４】
【発明の実施の形態】
以下本発明を実施形態により説明する。
【００２５】
（実施形態）
本実施形態の構成を図１〜図５に示す。器体１は、耐トラッキング性に優れた熱硬化性合成樹脂（例えば、ユリア樹脂）を用いて前面が開口された箱体状のボディ１Ａと、同じく耐トラッキング性に優れた熱硬化性合成樹脂（例えば、ユリア樹脂）を用いて後面が開口された箱体状のカバー１Ｂとを被着結合することにより形成されるもので、外形寸法は規定の単位寸法に基づいた寸法となっている。
【００２６】
ボディ１Ａは長手方向の中間部に設けた仕切壁３Ａにより内部を２分し、仕切壁３Ａの両側に刃受け部材５などの充電部材が収納される収納室２、２を設けている。またカバー１Ｂ内にも仕切壁３Ｂが図１に示されるように形成され、ボディ１Ａとカバー１Ｂとを結合するとボディ１Ａの仕切壁３Ａとカバー１Ｂの仕切壁３Ｂとが突き合わされることによって器体１の内部空間を独立した２室に分割するようなっている。
【００２７】
ここで仕切壁３Ａの端面には凸部４を一体に突設し、仕切壁３Ｂには凸部４を嵌め込む凹部６を形成しており、これら凸部４及び凹部６の両端部はボディ１Ａ、カバー１Ａの外側側面に至るとともに凹部６の両端が外部に開口している。
【００２８】
ボディ１Ａ内において仕切壁３Ａの両側の各収納室２には、それぞれ刃受け部材５が収納される。
【００２９】
各刃受け部材５は、互いに対向する一対のばね片５０と、両ばね片５０の一方の側面に対向するばね片５１と、ばね片５０、５１を連続一体に結合する連結片５２とを備え、互いに対向する一対のばね片５０で丸ピン型栓刃に弾接する刃受け部を、ばね片５１とこのばね片５１の板面に対向する一対のばね片５１の端面で平型栓刃に弾接する刃受け部を構成する。
【００３０】
また各連結片５２は中央に穿設している孔５２ａを挿通させたかしめ鋲１２を対応する端子金具１１の平板片１１ａの中央に穿設している孔１３に挿通してかしめることで端子金具１１に一体的に固定される。
【００３１】
各端子金具１１は、平板片１１ａの一端側には立片１１ｂ、１１ｂを板面に垂立するように延長形成し、この立片１１ｂ、１１ｂの一側端から外側方へ直角に折り曲げ形成した位置片１１ｃ、１１ｃを夫々形成してある。
【００３２】
また平板片１１の他端側縁に端子板８を板面に対して垂直に折り曲げ形成している。この端子板８の両側端には上記端子片１１ｃ、１１ｃに並行するように端子片１１ｄ、１１ｄを一体形成し、この端子片１１ｄ、１１ｄと端子板８の両側端とを連結する部位を平板片１１ａ側に夫々折曲し、また各端子片１１ｄの上端には小片１１ｅ、１１ｅを平板片１１ａ方向に折り曲げ形成してある。
【００３３】
而して端子金具１１を刃受け部材５とともにボディ１Ａの収納部２に収納するに当たっては、端子片１１ｃ、１１ｃを収納部２内に形成している位置決めリブ１４、１４に当接するとともに、端子板８の板面を仕切壁３Ａの壁面に図３（ａ）に示すように当接することで、端子金具１１及び刃受け部材５が収納部２内の定位置に位置決めして配置する。またこの配置時に並行する端子片１１ｃ、１１ｄの間に鎖錠ばね１５を配置する。
【００３４】
鎖錠ばね１５は帯板の一端部をＪ字状に曲成して接触片１５ａを形成するとともに、他端部をＳ字状に曲成して鎖錠片１５ｂを形成したものであって、接触片１５ａ及び鎖錠片１５ｂを端子片１１ｃに対向させる形でボディ１Ａに収納され、端子板８を含む端子金具１１とで速結端子装置を構成する。
【００３５】
ところで、上記にように両収納部２、２内に配置された端子金具１１の各端子板８、８の両端部は夫々仕切壁３Ａから離れるため、仕切壁３Ａを介して背中合わせの両端子板８の端部間距離は仕切壁３Ａに沿っている部位間の距離よりも大きくなる。
【００３６】
尚刃受け部材５の端子片１１ｃ及び鎖錠ばね１５はカバー１Ｂ内に設けた押さえリブ（図示せず）によりボディ１Ａから浮き上がらないように押さえられる。
【００３７】
ボディ１Ａの後壁には鎖錠ばね１５と端子片１１ｃとの間に電線を導入することができるように電線挿入孔（図示せず）が形成されている。この電線挿入孔を通して鎖錠ばね１５と端子片１１ｃとの間に、鎖錠片１５ａ側から電線を挿入すると、接触片１５ａ及び鎖錠片１５ａのばね力によって電線が端子片１１ｃとの間に挟持され、かつ鎖錠片１５ｂが電線に食い込むことによって電線を引き抜くことができなくなる。このように、電線挿入孔に電線を挿入するだけで結線することができるから、ねじ付きの端子などを用いる場合に比較して結線作業が容易になる。
【００３８】
各収納室２には、各刃受け部材５に設けた一対の端子片１１ｃにそれぞれ対向する一対の鎖錠ばね１５に跨がるように熱硬化性合成樹脂（例えばユリア樹脂等）の成型品からなる解除釦１７が配設される。解除釦１７は両鎖錠ばね１５の鎖錠片１５ｂに当接し、ボディ１Ａの後壁に沿ってスライド可能となるように配置されている。
【００３９】
解除釦１７が鎖錠片１５ｂに当接する部位は鎖錠片１５ｂが端子片１１ｃとの間に電線を挟持する部位からずれている。また、解除釦１７に対応する部位でボディ１Ａの後壁には操作孔１６が形成され、操作孔１６にマイナスドライバの先端部などを挿入して解除釦１７を押すことにより、電線に食い込んでいる鎖錠片１５ｂを電線から離すように撓ませて電線の引き抜きが可能となるようにしてある。
【００４０】
ところで、カバー１Ｂの天井部、つまり前壁には一つのプラグに設けた一対の栓刃を挿入することができる一対の栓刃挿入口７を形成しており、各栓刃挿入口７は各刃受け部材５のばね片５０、５１に対応する部位にそれぞれ開口し、平板状の平型栓刃が差し込まれる平型栓刃挿入口７ａと、丸ピン型栓刃が差し込まれる丸ピン型栓刃挿入口７ｂとを連通させた形状に形成されている。つまり、平型栓刃挿入口７ａは矩形状であって、長手方向の中間部の一側縁に円状の丸ピン型栓刃挿入口７ｂが連通した形状になっている。また、平型栓刃挿入口７ａの中心間の距離よりも、丸ピン型栓刃挿入口７ｂの中心間の距離の方が広くなっている。平型栓刃挿入口７ａに挿入される平型栓刃はばね片５０の側面とばね片５１との間で挟持され、丸ピン型栓刃挿入口７ｂに挿入される丸ピン型栓刃は一対のばね片５０の間で挟持される。尚平型栓刃挿入口７ａは電圧線側と接地線側とで長さ寸法を異ならせてある。
【００４１】
また栓刃挿入口７、７を非栓刃挿入時において閉鎖する栓刃挿入口閉鎖手段を栓刃挿入口７、７の下方に配置してある。
【００４２】
この、栓刃挿入口閉鎖手段は、扉体９、コイルばね１８並びに中枠１９とから構成され、コイルばね１８により弾性付勢される扉体９で栓刃挿入口７を開閉自在に塞ぐものである。
【００４３】
そしてカバー１Ｂの内部に一対の扉体９、９と一対のコイルばね１８、１８、そして中枠１９が納められる。中枠１９は一対の貫通孔１９１、１９１と、この貫通孔１９０、１９０の間に位置する溝１９１と、各貫通孔１９１の両側に位置する突部１９２、１９２とを備えたもので、カバー１Ｂ内壁に設けられた突起（図示せず）との係合でカバー１Ｂに仮止めすることができるものとなっている。そして、上記の一対の扉体９、９と一対のコイルばね１８、１８とは該中枠１９とカバー１Ｂの内面との間に配設される。
【００４４】
同形のものとして形成されている一対の扉体９、９は、両端部に張り出す翼片９２、９２と、中央部９に他方の扉体９側に突出する棒状の支点部９１とを備えたもので、支点部９１は中央よりも翼片９１側に寄った位置に設けられており、両扉体９、９を相対させて組み合わせたとき、支点部９１、９１同士が並ぶとともに、相互にスライド自在となっている。また、各翼片９１、９１の上面は他方の扉体９側が低くなる傾斜面となっており、この傾斜面が栓刃押入時の押入力を受けて扉体９、９を反対向方向へ動かす力に変換する刃受け斜面１０ａ、１０ｂを構成する。刃受け斜面１０ａが平型栓刃挿入口７ａに、刃受け斜面１０ｂが丸ピン型栓刃挿入口７ｂに夫々対向する。
【００４５】
これら扉体９、９は、上記支点部９１、９１が中枠１９の溝１９１に納められるとともに、その外面側とカバー１Ｂの内壁との間にコイルばね１８、１８が配された状態でカバー１Ｂ内に納められ、コイルばね１８、１８による付勢で両扉体９、９は相互に接する状態となる。
【００４６】
中枠１９及び扉体９、９を納めたカバー１Ｂは、後述する組立枠２０を用いてボディ１Ａと結合されるのであるが、ボディ１Ａとカバー１Ｂとを組立枠２０で結合して器体１を組み立てたとき、中枠１９の貫通孔１９１内に刃受け部材５のばね片５０、５１からなる刃受け部が位置するとともに、中枠１９はボディ１Ａにおける仕切壁３Ａと係合して、両刃受け部間を分離し、プラグの抜き差しによって発生する切り粉の回り込みで短絡が生じてしまうことを防いでいる。また、貫通孔１９１の内部に刃受け部を位置させることで、ばね片５０、５１の異常開きを阻止している。そして扉体９、９は、カバー１Ｂの栓刃挿入口７と刃受け部材５との間に位置する。
【００４７】
すなわち、一方の扉体９の翼片９１は他方の扉体９の翼片９１に少し被さることで隙間が両扉体９、９間に生ずることがない状態で両扉体９、９がコイルばね１８、１８による付勢で接触しているのであるが、このように閉じた扉体９、９が挿入口７と刃受け部材５との間に位置して、挿入口７の奥に位置する刃受け部材５を隠すことになる。
【００４８】
ここにおいて、カバー１Ｂの内面には、図示しない位置決めリブが突出しており、コイルばね１８で付勢されている扉体９は当接面１６６を位置決めリブに当接させることで、両扉体９、９は閉じた状態の位置が定められる。
【００４９】
この状態で、プラグの栓刃を両挿入口７に差し込めば、各栓刃は扉体９、９の翼片９１、９１の傾斜面１６３を押すことで、扉体９をコイルばね１８に抗して動かして、両扉体９、９の間を広げるものであり、このために栓刃は刃受け部材５にまで達して、栓刃が平型のものであればばね片５０、５１からなる刃受け部に、丸ピン型のものであれば一対のばね片５０、５０からなる刃受け部に差し込まれる。プラグを抜けば、両扉体９、９はコイルばね１８、１８による付勢で復帰して再度挿入口７を閉じる状態となる。
【００５０】
そして、この扉付きコンセントにおいては、プラグにおける一対の栓刃が同時に差し込まれないとき、つまり片側の栓刃のみが差し込まれるときには、扉体９、９が開かず、片方の栓刃のみが刃受け部に差し込まれるという状態が生じないようになっている。すなわち、片方の栓刃のみを差し込んだときや異物を隙間に差し込むときには、両扉体９、９は中枠１９の溝１９１によって受けられている支点部９１、９１を中心として栓刃で押されて片側に傾くものであり、この傾きによって、翼片９１、９１は中枠１９の突部１９２、１９２間に入り込み、栓刃が栓刃受け斜面１０ａ、又は１０ｂを押すことで両扉体９、９を押し開こうとしても、ストッパーである突部１９２との干渉で開くことがないものである。尚栓刃を差し込んだとき、傾斜面１６３に栓刃が当たる関係で、上下方向にも扉体９が傾こうとするが、この傾きは支点部９１で阻止される。
【００５１】
ここで、一対のコイルばね１８、１８を扉体９、９の間に設けずに両サイドに設けているのは、扉体９、９の開閉によってコイルばね１８、１８が折れても異極間の短絡が生じることがないようにしている意味を有している。尚扉体９におけるコイルばね１８を受ける部分は、内部にボス２１が突出する穴２２として形成されており、コイルばね１８を穴２２に嵌め込めば、根元が太くなっているボス２１にコイルばね１８が係合するようになっている。組み立てに際しては、扉体９にコイルばね１８を組み付けた状態でカバー１Ｂ内に組み入れるわけであるが、コイルばね１８が扉体９から抜け落ちることがなくて、組み立て作業性が良いものである。

ところで、上記の内部部材を収納してボディ１Ａとカバー１Ｂとを結合する際にはボディ１Ａとカバー１Ｂとの双方に設けた嵌合部２３、２４に組立部材たる組立枠２０を凹凸嵌合することでボディ１Ａとカバー１Ｂとが結合され、所望のコンセントが完成することになる。
【００５３】
さて実施形態のコンセントではボディ１Ａとカバー１Ｂとを被着結合したときに側の仕切壁３Ａの凸部４がカバー１Ｂ側の凹部６に嵌る込むことになり、そのためボディ１Ａの両側の収納部２、２に収納された刃受け部材５等の充電部間の絶縁距離を長くすることができ、絶縁性能を高めることができるのである。また部品寸法のばらつきよってできる凹部６と凸部４の隙間に、栓刃等から出る金属粉が入っても凹部６の両端部６ａ、６ａが外部に開口しているため、壁面に配設した際に下側となる凹部６の端部６ａから金属粉が外部へ排出されるため、金属粉の繋がりによって絶縁破壊の経路が形成されることもなく、電気面で安全性の高いコンセントを提供できる。
【００５４】
また仕切壁３Ａに沿って配設される端子板８の両端が仕切壁３Ａより離れるように形成されているため、部品の寸法ばらつきによって上述のような隙間が凹部６と凸部４の間にでき、壁面に配設した際に下側となる凹部６の端部６ａに隙間から侵入してきた金属粉が落下してきても、両側の端子板８、８の下端間の絶縁距離が長く取れるため短絡発生を防止できる。この端子板８、８の構成を用いる場合、従来と同様に図６に示すように凹部６の端部が閉じられている場合にも短絡発生に対する防止策として有効である。
【００５５】
また本実施形態のコンセントでは、上述した栓刃挿入口閉鎖手段の扉体９、９の中央部９の垂立面９ａの位置（図１０参照）が、部品寸法ばらつきが多少あっても、平型栓刃挿入口５ａの内壁面よりも、例えば１ｍｍ程度奥方向、つまりカバー１Ｂの天井部方向側に必ず位置するよう、扉体９の寸法設定を行っており、そのため図７に示すように平型栓刃挿入口５ａを介して外部から両扉体９の垂立面９ａにおける突き合わせ部位の隙間が見えなくなる。結果、この隙間に物を差し込めなくなり、子供の悪戯などによる事故防止を図れる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to embodiments.
[0025]
(Embodiment)
The configuration of the present embodiment is shown in FIGS. The casing 1 is made of a box-shaped body 1A having a front opening using a thermosetting synthetic resin (for example, urea resin) having excellent tracking resistance, and a thermosetting synthetic resin also having excellent tracking resistance. (For example, urea resin), and is formed by attaching and bonding to a box-shaped cover 1B having an open rear surface, and the outer dimensions are based on prescribed unit dimensions.
[0026]
The interior of the body 1A is divided into two parts by a partition wall 3A provided at an intermediate portion in the longitudinal direction, and storage chambers 2 and 2 for storing a charging member such as a blade receiving member 5 are provided on both sides of the partition wall 3A. Also, a partition wall 3B is formed in the cover 1B as shown in FIG. 1, and when the body 1A and the cover 1B are connected, the partition wall 3A of the body 1A and the partition wall 3B of the cover 1B abut against each other. The internal space of the body 1 is divided into two independent rooms.
[0027]
Here, a projection 4 is integrally formed on the end face of the partition wall 3A, and a concave portion 6 is formed on the partition wall 3B. The concave portion 6 into which the convex portion 4 is fitted. 1A and the outer side surface of the cover 1A, and both ends of the concave portion 6 are open to the outside.
[0028]
Blade receiving members 5 are stored in the respective storage chambers 2 on both sides of the partition wall 3A in the body 1A.
[0029]
Each blade receiving member 5 includes a pair of spring pieces 50 opposed to each other, a spring piece 51 opposed to one side face of both spring pieces 50, and a connecting piece 52 for connecting the spring pieces 50 and 51 continuously and integrally. The blade receiving portion elastically contacting the round pin type blade with a pair of spring pieces 50 facing each other is formed into a flat blade by the spring piece 51 and the end face of the pair of spring pieces 51 facing the plate surface of the spring piece 51. A blade receiving portion that makes elastic contact is configured.
[0030]
Each connecting piece 52 is formed by inserting a caulking stud 12 into a hole 13a formed in the center of the flat plate piece 11a of the corresponding terminal metal fitting 11 through a hole 52a formed in the center. It is integrally fixed to the terminal fitting 11.
[0031]
Each of the terminal fittings 11 is formed by extending the standing pieces 11b, 11b on one end side of the flat plate piece 11a so as to be perpendicular to the plate surface, and bending the standing pieces 11b, 11b outwardly at right angles from one side end thereof. Position pieces 11c, 11c are formed respectively.
[0032]
Further, a terminal plate 8 is formed on the other end side edge of the plate piece 11 by bending it perpendicularly to the plate surface. Terminal strips 11d, 11d are integrally formed on both side ends of the terminal plate 8 so as to be parallel to the terminal strips 11c, 11c, and a portion connecting the terminal strips 11d, 11d and both side ends of the terminal plate 8 is flat.
