Description

【０００１】
【発明の属する技術分野】
本発明は、スイッチやコンセントのような配線器具の器体に収納されて電線を接続する速結端子装置に関するものである。
【０００２】
【従来の技術】
従来より、端子板と錠ばねとを備えた速結端子装置を端子部に用いた配線器具が提供されている。このような配線器具では、図４２に示すように器体１０１の背面に電線挿通用の挿通孔１０２を設けてあり、挿通孔１０２から導入される電線１０４に接触する端子板と、ばね力を利用して端子板との間で電線１０４の芯線を挟持する接触片及び電線１０４の一部に食い込むことで電線１０４を鎖錠する鎖錠片を具備した鎖錠ばねと、鎖錠片を端子板から離れる方向に押圧するための解除釦とを器体１０１の内部に収納してある（例えば特許文献１参照）。
【０００３】
ここで、端子部に電線１０４を接続する際には、被覆が剥かれた電線１０４の芯線を挿通孔１０２から器体１０１の内部に挿入すると、電線１０４の芯線が端子板と鎖錠ばねとの間に挿入され、接触片及び鎖錠片と端子板との間で電線１０４の芯線が挟持されるとともに、鎖錠片の先端が芯線に食い込むことによって、芯線の脱落が防止される。したがって、この速結端子装置では挿通孔１０２から電線１０４の芯線を挿入するだけで、電線１０４の芯線を接続できるようになっている。

【０００５】
【発明が解決しようとする課題】
ところで、上述の速結端子装置から電線１０４の芯線を外す場合は、器体１０１の背面に開口した操作孔１０３からマイナスドライバー１１０の先端を挿入して解除釦を押圧することによって、解除釦により鎖錠ばねの鎖錠片を端子板から離れる方向に撓ませており、鎖錠片が電線１０４の芯線から離れ、鎖錠状態が解除されるので、電線１０４を器体１０１から引き抜くことができる。しかしながら、片方の手で配線器具の器体１０１を持ち、もう一方の手に持ったマイナスドライバー１１０を操作孔１０３に挿入して解除釦を押した状態では、両方の手が塞がってしまうため、電線１０４を挿通孔１０２から引き抜くことが困難であった。
【０００６】
本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、電線の引き抜き作業を容易に行える速結端子装置を提供することにある。
【０００７】

【発明の実施の形態】
以下、本発明に係る速結端子装置をコンセントの端子部に適用した実施形態について図面を参照して説明する。但し、配線器具はコンセントに限定されるものではなく、例えばスイッチなどのコンセント以外の配線器具にも本発明の技術思想が適用可能であることは言うまでもない。
【００２９】
（実施形態１）
本発明の実施形態１を図１〜図２４に基づいて説明する。尚、以下の説明では特に断りがない限り、図２（ａ）に示す向きにおいて上下左右の方向を規定し、図２（ａ）における正面を前面とする。したがって、同図（ｂ）における右端は後端となる。
【００３０】
コンセントの器体１は、図１〜図４に示すように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）を用いて前面が開放された略函形に形成されたボディ２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）を用いて後面が開放された略函形に形成されたカバー３とを、後述する組立枠４を用いて結合することにより形成され、器体１の内部には電圧極用の導電部材４０ａ，４０ｂと接地極用の導電部材４０ｃと３個の解除レバー５０とが納装されている。
【００３１】
カバー３の前壁には、図７及び図８に示すように、突台状のボス部３ａが突設され、長手方向に沿う両側面の中央部には肩部３ｂが突設されている。また、ボス部３ａの前面には、栓刃や導電ピン等の接触子が挿入される一対の接触子挿入口６，６から成るコンセント口（所謂ユニバーサル型のコンセント口）５と、各々に接地極を含む平板状の栓刃が挿入される３個の接触子（栓刃）挿入口８…から成るコンセント口（３極のコンセント口）７とが長手方向に並べて１口ずつ設けてある。
【００３２】
ユニバーサル型のコンセント口５の各接触子挿入口６，６は平板状の栓刃や円柱状の導電ピン等の種々の接触子に対応可能な形状、すなわち、栓刃が挿入される矩形孔６ａと導電ピンが挿入される半円形孔６ｂとを一体に連通させた形状に形成してある。また、３極のコンセント口７の各接触子挿入口８…は平板状の栓刃に対応させて矩形に形成され、接地極の栓刃が挿入される接触子挿入口８ａの両側に残り（電圧極）の接触子挿入口８ｂ，８ｂが逆ハ字形に配置してある。また、ボス部３ａの前壁の裏面には、接触子挿入口６，６の間の部位と、接極子挿入口８ｂ，８ｂの間の部位とからそれぞれ後方に突出する絶縁壁９，９が突設されている。
【００３３】
一方、ボディ２の略中央には、図５及び図６に示すように底部より立設された周壁１１で周りを囲まれて、接地極用の導電部材４０ｃが収納される収納凹部１２が形成されている。この収納凹部１２の底部には、後述する解除レバー５０のレバー部５４を挿通する貫通孔２ｆが貫設されている。貫通孔２ｆの両側部には収納凹部１２の底部からリブ１１ａが立設されており、このリブ１１ａによって収納凹部１２の内部が後述の刃受部３２を収納する刃受部収納室１２ａと、後述の端子部２０’を収納する端子部収納室１２ｂとに仕切られている。また収納凹部１２の外側には、底部より立設された隔壁１３によって左右２つの空間に仕切られて、それぞれ電圧極用の導電部材４０ａ，４０ｂを収納する収納凹部１４，１４が形成されている。各収納凹部１４は、底部より立設された隔壁１６によってさらに３つの空間に仕切られ、後述の刃受部３０，３１をそれぞれ収納する刃受部収納室１４ａが長手方向の両側に設けられるとともに、後述の端子部２０を収納する端子部収納室１４ｂが長手方向の中間部に設けられる。ここで、電圧極側の端子部収納室１４ｂ，１４ｂと接地極側の端子部収納室１２ｂとがボディ２の左右方向に並べて設けられており、端子部収納室１２ｂ，１４ｂの底部には外部より電線を導入するための電線挿入孔１５が２個ずつ開口している。また、ボディ２の長手方向に沿う両側壁にはカバー３の肩部３ｂに対応する部位に膨出部２ａが形成されており、この膨出部２ａには端子部収納室１４ｂと連通する縦溝１７が前後方向に沿って形成されている。また、膨出部２ａの表面には縦溝１７の上下両側縁に段部１７ａ，１７ａが形成されており、縦溝１７の後側には円弧状に窪んだ凹部１７ｂが形成されている。なお、カバー３の肩部３ｂ，３ｂの後縁には、縦溝１７，１７に嵌合する凸部３ｅ，３ｅが突設されている。
【００３４】
ここで、ボディ２の収納凹部１４に収納される導電部材４０ａ又は４０ｂと解除レバー５０について以下に説明を行う。導電部材４０ａ，４０ｂは端子板２１及び刃受部３０，３１を一体に連結して構成され、端子板２１と解除レバー５０とで端子部２０（速結端子装置）が構成される。なお、導電部材４０ａ，４０ｂは面対称に形成されており、互いに鏡像の関係にあるので、以下では導電部材４０ａについて図１０〜図１２を参照して説明を行い、導電部材４０ｂについては説明を省略する。
【００３５】
刃受部３０は、ばね性を有する金属板を加工することによって、コ字形の基部３０ｃと、基部３０ｃの両側片先端部の前端縁から突設されて互いに対向配置される一対の導電ピン用刃受ばね３０ａと、基部３０ｃの中央片の前端縁から両刃受ばね３０ａと略直角に突設された栓刃用刃受ばね３０ｂと、基部３０ｃの一側片の先端部から延設され後述する端子板２１にかしめ固定される固定片３０ｄとを連続一体に形成してある。
【００３６】
刃受部３１は、ばね性を有する金属板を加工することによって、コ字状の基部３１ｂと、基部３１ｂの両側片の前端縁から突設されて互いに対向配置される一対の刃受ばね３１ａと、基部３１ｂの一側片の先端部から延設され後述する端子板２１にかしめ固定される固定片３１ｃとを連続一体に形成してある。
【００３７】
また、端子板２１は、図１０〜図１２に示すように、略凸字形の主片２１ａと、主片２１ａの幅狭の一端側の両側部から後方（図１２における下方、以下同じ）へそれぞれ垂下された接触片２２，２２と、主片２１ａの幅広の他端側の両側部から後方へそれぞれ垂下された略Ｊ字形の鎖錠片２３，２３と、鎖錠片２３，２３の側端縁から側方へ突出する連結片２５，２５とを有し、弾性を有する帯状の金属板を加工することで、接触片２２の先端部と鎖錠片２３の先端部が交差するように折り曲げて一体に形成される。接触片２２にはほぼ平坦な面を有して電線に弾接する接触部２２ａと、電線の挿入方向に沿った接触部２２ａの両側において電線を押圧する一対の押圧部２２ｂ，２２ｃが設けられている。また、接触片２２に対して内側に位置する鎖錠片２３には、電線を接触部２２ａの方へ押圧するとともに電線の一部に食い込んで抜け止めする鎖錠部２３ａと、鎖錠部２３ａよりも接触片２２に近づく向きに突出する受け部２３ｃとが先端に並設され、鎖錠部２３ａよりも後方の部位に電線（接触片２２）から離れる向きに凸となる曲げ部２３ｂが設けられている。なお、図１０（ｂ）に示すように鎖錠部２３ａが接触片２２に対向するとともに受け部２３ｃが接触片２２と対向しないように、接触片２２の幅寸法が鎖錠片２３の幅寸法のおよそ半分に設定されている。また、各連結片２５には刃受部３０，３１の連結片３０ｄ，３１ｃに突設された一対の突起が挿通される挿通孔２５ａが一対ずつ貫設されており、これら一対の挿通孔２５ａに挿通した突起をかしめることで刃受部３０，３１の連結片３０ｄ，３１ｃに連結片２５が固定される。
【００３８】
一方、解除レバー５０は合成樹脂成型品からなり、図１４〜図１６に示すように、ボディ２に設けられた軸受け台１８に摺動自在に載置される円柱状の軸部５１と、軸部５１における軸受け台１８との摺接部位以外の円周面から外側に向かって突出し、先端面に軸部５１と同心で軸部５１よりも大径の円周面が形成された支持部５２と、支持部５２の円周方向における一端部の両側面から側方に向かって突出し、一面を軸部５１と同心で支持部５２の円周面よりも径の小さい円周面とした略三角柱状の押動部５３，５３と、支持部５２の円周方向における一端部から斜めに突出するＴ字形の操作部５４とを一体に形成して構成される。尚、軸部５１における軸受け台１８側の半円部５１ａは、残りの半円部に比べて肉厚に形成されており、軸受け台１８と接触する部分を肉厚とすることで、回転運動を行う際に軸受け台１８からの荷重が加わる半円部５１ａの強度を高めている。
【００３９】
そして、この解除レバー５０は、縦溝１７を通して操作部５４の先端部がボディ２の外に露出され、端子部収納室１４ｂの底部に設けられた軸受け台１８に軸部５１を載置するとともに、支持部５２の円周面を膨出部２ａ（ボディ２）の内壁に当接させることで、軸部５１を支点に器体１の前後方向に沿って回動自在に配設される（図１８（ａ）（ｂ）参照）。そして、端子部収納室１４ｂに解除レバー５０を収納した後に、各一対の刃受部３０、３１がそれぞれ隣り合うようにして、端子板２１と該端子板２１の連結片２５，２５に固定された刃受部３０，３１からなる導電部材４０ａ，４０ｂを、ボディ２の収納凹部１４に収納すると、解除レバー５０の押動部５３，５３が、端子板２１の鎖錠片２３，２３における受け部２３ｃ，２３ｃと当接する（図１７及び図１８参照）。
【００４０】
次に、ボディ２の収納凹部１２に収納される導電部材４０ｃ及び解除レバー５０について説明する。導電部材４０ｃは、図１及び図１３に示すように端子板２１’と刃受部３２とを一体に連結して構成され、端子板２１’と解除レバー５０とで接地極側の端子部２０’（速結端子装置）が構成される。
【００４１】
刃受部３２は、ばね性を有する金属板を加工することによって、略コ字形の基部３２ｂと、基部３２ｂの両側片の先端縁から突設されて互いに対向配置される一対の栓刃用刃受ばね３２ａと、側面視の形状がＬ字形に形成され、基部３２ｂの中央片から連続一体に延出して端子板２１’の中央片２１ａにかしめ固定される連結片３２ｃとを連続一体に形成してある。また、端子板２１’は連結片２５を無くした点以外は端子部２０の端子板２１と同様の構造を有しているので、共通する構成要素には同一の符号を付して、その説明は省略する。
【００４２】
解除レバー５０は、端子部２０の解除レバー５０と同一形状且つ同一寸法であるので、その説明は省略する。解除レバー５０は、凹部１２の底部に設けた貫通孔２ｆを通して操作部５４の先端部がボディ２の外に露出され、端子部収納室１２ｂの底部に設けられた軸受け台１８に軸部５１を載置することによって、軸部５１を支点に器体１の前後方向に沿って回動自在に配設される。そして、端子部収納室１２ｂに解除レバー５０を収納した後に、端子板２１’と該端子板２１’の中央片２１ａに固定された刃受部３２からなる導電部材４０ｃを収納凹部１２に収納すると、解除レバー５０の押動部５３，５３が、端子板２１’の鎖錠片２３，２３における受け部２３ｃ，２３ｃと当接する。
【００４３】
そして、以上のような端子部２０，２０’に電線を接続する際は、電線挿入孔１５を通して端子板２１，２１’の接触片２２と鎖錠片２３との間に電線を挿入すると、鎖錠片２３の鎖錠部２３ａが電線に食い込むことによって電線が抜け止めされるとともに、鎖錠片２３のばね力によって電線が接触片２２の接触部２２ａに弾接し、さらに電線は一対の押圧部２２ｂ，２２ｃによって鎖錠片２３の方へ押圧されるから、鎖錠部２３ａと押圧部２２ｂ，２２ｃの押圧力とが均衡して電線が挟持される。すなわち、端子部２０，２０’は電線挿入孔１５に電線を挿入するだけで結線することが可能な速結端子となっている。ここに、鎖錠片２３から電線接続手段が構成され、端子板としての接触片２２と鎖錠片２３とを一体に連結することで端子板２１，２１’を形成してある。
【００４４】
一方、端子部２０，２０’から電線を外す際には、器体１を持った一方の手でボディ２の縦溝１７或いは貫通孔２ｆから露出する操作部５４を器体１の前側に押すと、軸部５１ａを支点に解除レバー５０が回動し、押動部５３が鎖錠片２３の受け部２３ｃを押圧することによって、電線に食い込んでいる鎖錠部２３ａを接触片２２（電線）から離れる向きに撓ませるので、他方の手で電線挿入孔１５から電線を引き抜くことができ、従来に比較して電線の取り外し作業が容易に行える。その後、操作部５４を押す力を無くすと、解除レバー５０は鎖錠片２３のばね力によって初期位置まで回転する。
【００４５】
なお、本実施形態では支持部５２の両側面に一対の押動部５３を突設してあるので、解除レバー５０により２個の鎖錠片２３を同時に撓ませて、２本の電線を同時に引き抜くことができる。また、２個の鎖錠片２３を同時に撓ませるため、１個の鎖錠片２３を撓ませる場合に比べて約２倍の操作力が必要になるが、解除レバー５０はてこの原理を使って押動部５３により鎖錠片２３を押し動かしているため、操作部５４にかかる荷重が低減できる。そのうえ、回動支点となる軸部５１を鎖錠片２３の内側に配置しているので、軸部５１の回動中心Ｏから操作部５４の操作点Ａまでの距離ａと、回動中心Ｏから押動部５３による鎖錠部２３ａの押圧点Ｂまでの距離ｂとの比率（梃子比ａ：ｂ）をできるだけ大きくとることができ、梃子比をかせぐことによって、できるだけ小さな操作力で鎖錠部２３ａを撓ませることができる。
【００４６】
ところで、解除レバー５０を回動自在に支持するためには、軸部５１ａの円周面を軸受け台１８に載置するとともに、解除レバー５０を別の方向（前方或いは側方）から支持する必要があり、本実施形態では図１８（ａ）に示す非解除操作位置（解除操作を行っていない時の位置）において押動部５３（第１の押さえ部）の円周面を膨出部２ａの内壁に当接させることで、側方から支持し、図１８（ｂ）に示す解除操作位置（回転位置）において支持部５２（第２の押さえ部）の円周面を端子板２１の中央片２１ａに当接させることで、解除レバー５０を前方から支持している。軸部５１の円周面を軸受け台１８との間で挟持することで解除レバー５０を枢支するためには、軸部５１の円周面を前方から押さえる部材が別途必要になるが、本実施形態では解除レバー５０の回動に伴って、解除レバー５０を押さえる部位を押動部５３の円周面から支持部５２の円周面に移行させているので、別途の部材を追加することなく、端子板２１の中央片２１ａなどで解除レバー５０を枢支することができる。
【００４７】
また、解除操作時以外で電圧極用の解除レバー５０の操作部５４が膨出部２ａの表面よりも外側に突出していると、器体１の施工時に操作部５４の突出部位が邪魔になったり、器体１の周りに配設してある電線などが操作部５４に当たって電線が外れる可能性があるが、本実施形態では、非解除操作時に操作部５４の先端位置が膨出部２ａの表面よりも後退した位置となるように解除レバー５０を配置しているので（図１７参照）、ボディ２の表面から外側に突出する部分がなく、器体１の施工の邪魔になったり、器体１の周りに配設してある電線などが操作部５４に当たって電線が外れるのを防止できる。また、接地極用の解除レバー５０の操作部５４を挿通する貫通孔２ｆは、ボディ２の後面に形成された凹部２ｇの底に形成されているので、図１９及び図２０に示すように、操作部５４の先端がボディ２の後面から外側に突出することがなく、さらに解除操作時には操作部５４の先端を凹部２ｇの底側に倒すように押し込めば良い。このように凹部２ｇを設けて、凹部２ｇの底の貫通孔２ｆから解除レバー５０の操作部５４を露出させているので、初期状態における解除レバー５０と端子板２１，２１’との位置関係を電圧極側と接地極側とで同じ位置関係にして、電圧極側と接地極側とで解除レバー５０を共通化することができ、その結果、開発や製造に必要な投資を抑制したり、部品の種類を減らすことで品質管理が容易になるという効果が得られる。
【００４８】
また、図２０に示すように、膨出部２ａの表面には操作部５４との対向部位に円弧状に窪んだ凹部１７ｂが設けられ、さらに凹部２ｇの内側面における操作部５４との対向部位にも円弧状に窪んだ凹部１７ｂが形成されているので、凹部１７ｂと操作部５４との間に手の指を入れやすく、電線解除時に操作部５４を容易に引き出すことができる。
【００４９】
また、本実施形態では操作部５４の先端部に、操作部５４に対して直交する方向に延びる三角柱状の操作片５４ａを突設しており、この操作片５４ａを操作することで、解除レバー５０を回転させているのであるが、解除レバー５０を初期位置に戻す際に、段部１７ａ，１７ａと凹溝１７ｂとの角部に操作片５４ａの両側縁がこすれるような位置関係に設定してある。したがって、解除レバー５０を非解除操作位置に戻そうとすると、段部１７ａと凹部１７ｂとの角部に操作片５４ａの両側縁が当たって操作部５４が撓み、この角部を操作片５４ａが乗り越えることで、解除レバー５０が初期位置に仮固定されるから、解除レバー５０が不用意に動いて電線の鎖錠状態が解除されるのを防止できる。ここに、段部１７ａと凹部１７ｂとでできる角部と、操作部５４の操作片５４ａとで解除レバー５０を仮保持する保持手段が構成される。
【００５０】
なお、操作片５４ａの先端部が細いと、手に加わる圧力が高くなって、手が痛くなるため、図２４に示すように、図１７の操作片５４ａに比べて幅寸法の大きな操作片５４ｂを設けても良く、操作片５４ｂの内側面（ボディ２の側壁との対向面）５４ｃは解除操作時に指を入れるため、丸みを持たせるのが望ましい。
【００５１】
ところで、上述のように構成される導電部材４０ａ，４０ｂは、ボディ２の四隅に設けた刃受部収納室１４ａに刃受部３０，３１を収納するとともに、端子部収納室１４ｂに端子板２１を収納するようにして、ボディ２の各収納凹部１４に納装される。なお、両収納室１４ａ，１４ｂを仕切る隔壁１６には端子板２１の連結片２５，２５を挿通するためのスリット１６ａを設けてある。また導電部材４０ｃは、ボディ２の刃受部収納室１２ａに刃受部３２を収納するとともに、端子部収納室１２ｂに端子板２１’を収納するようにして収納凹部１２内に収納される。そして、ボディ２の開口面にカバー３を突き合わせた状態では、刃受部３０とカバー３の前壁に設けたユニバーサル型のコンセント口５の接触子挿入口６とが対向するとともに、刃受部３１，３２と３極のコンセント口７の接触子挿入口８ｂ，８ａとが対向することになる。
【００５２】
ここで、接触子挿入口６から対向する一対の刃受ばね３０ａの間に円柱状の導電ピンが挿入されると、一対の刃受ばね３０ａの間に導電ピンが弾性挟持されて、導電部材４０ａ，４０ｂと導電ピンとが電気的に接続され、一対の刃受ばね３０ａの側縁と刃受ばね３０ｂとの間に平板状の栓刃が挿入されると、一対の刃受ばね３０ａの側縁と刃受ばね３０ｂとの間で栓刃が弾性挟持されて、導電部材４０ａ，４０ｂと栓刃とが電気的に接続されるのである。また接触子挿入口８から一対の刃受ばね３１ａの間に平板状の栓刃が挿入されると、一対の刃受ばね３１ａの間に栓刃が弾性挟持されて、導電部材４０ａ，４０ｂと栓刃とが電気的に接続されるのである。また接触子挿入口８ａから対向する一対の刃受ばね３２ａの間に平板状の栓刃が挿入されると、一対の刃受ばね３２ａの間に栓刃が弾性挟持され、導電部材４０ｃと栓刃とが電気的に接続されるのである。ここに、刃受部３０の一対の刃受ばね３０ａ、刃受部３１の一対の刃受ばね３１ａ、並びに刃受部３２の一対の刃受ばね３２ａは、ともに対向する互いの間隔が前方ほど幅狭となるように傾斜し且つ前端間が導電ピンあるいは栓刃が挿入し易いように前方ほど間隔が拡がるように傾斜させてあり、導電ピンあるいは栓刃が挿入し易いようになっている。また、刃受部３０の刃受ばね３０ｂも、刃受ばね３０ａとの間隔が前方ほど幅狭となるように傾斜し且つ前端間は栓刃が挿入し易いように前方ほど間隔が拡がるように傾斜させてあり、栓刃が挿入し易いようにしてある。
【００５３】
次に、ボディ２とカバー３とを結合して器体１を組み立てる構造について説明する。本実施形態においては、ボディ２とカバー３との双方に設けた嵌合突起２ｂ，３ｃに組立枠４を凹凸嵌合することでボディ２とカバー３とを結合して器体１を組み立てるようになっている。
【００５４】
ボディ２の長手方向に沿う両側面には膨出部２ａの両側部に角柱状の嵌合突起２ｂが突設され、さらに嵌合突起２ｂの前側（図５（ｂ）における左側）には凹溝２ｃが形成されている。また、カバー３の長手方向に沿う両側面には、嵌合突起２ｂと同形状且つ同寸法の嵌合突起３ｃが肩部３ｂの両側部に突設されており、ボディ２の開口面にカバー３を突き合わせた状態では、それぞれの嵌合突起２ｂ，３ｃが凹溝２ｃを挟んで前後方向に一列に配置されることになる。
【００５５】
一方、組立枠４は弾性を有する合成樹脂成型品からなり、図９（ａ）〜（ｃ）に示すように嵌合突起２ｂ，３ｃと各々嵌合する嵌合孔４ｂ，４ｂが長手方向に並設された短冊状の縦片４ａを有し、器体１と対向する縦片４ａの背面側において嵌合孔４ｂ，４ｂで挟まれた略中央部からは先端に係止爪４ｄを有する係止突片４ｃが背方へ突設されている。また、縦片４ａの前端面には、埋込型の配線器具を造営面に埋込配設するための取付枠、又は配線器具の取付構造を有したフラッシプレート（以下、単に「プレート」という）が具備する係合孔と係合して器体１を取付枠又はプレート枠に取り付けるための取付爪４ｅが突設されている。そして、カバー３の長手方向に沿う両側壁の後縁には、嵌合突起３ｃ近傍の部位に、後方に向かうにつれて内側に傾斜するガイド面３ｄが形成されている。
【００５６】
而して、ボディ２とカバー３とを結合して器体１を組み立てるには、ボディ２とカバー３を開口面側で突き合わた状態で係止突片４ｃを凹溝２ｃに挿入するように組立枠４を器体１の長手方向に対向する両側面の方へ押しつければ、組立枠４の各嵌合孔４ｂ，４ｂにボディ２及びカバー３の嵌合突起２ｂ，３ｃがそれぞれ嵌合してボディ２とカバー３とが結合されると同時に、係止突片４ｃの先端に設けた係止爪４ｄがカバー３の両側壁のガイド面３ｄに沿うように係止突片４ｃが後方に撓み、やがて係止突片４ｃの係止爪４ｄがカバー３の両側壁の開口縁に係止することによって、組立枠４の嵌合突起２ｂ，３ｃからの脱落が防止でき、ボディ２とカバー３とが結合されるのである。
【００５７】
（実施形態２）
図２５に本実施形態の速結端子装置に用いる解除レバー５０’の側面図を、図２６にこの解除レバー５０’を端子板２１に組み込んだ状態の側面図をそれぞれ示す。この解除レバー５０’は電圧極側の端子部２０から電線を外すためのものであり、電圧極側の解除レバー５０’以外は実施形態１と同様であるので、共通する構成要素には同一の符号を付して、その説明は省略する。
【００５８】
解除レバー５０’は合成樹脂成型品からなり、ボディ２に設けられた軸受け台１８に摺動自在に載置される円柱状の軸部５１と、側面視の形状が略Ｌ字形に形成され、軸部５１における軸受け台１８との摺接部位以外の円周面から外側に向かって突出する連結部５５と、連結部５５の縦片５５ｂの先端部両側面に突設された押動部５６と、連結部５５の先端部から連結部５５の横片５５ａと略平行な方向に突出するＴ字形のレバー部５７とを一体に形成して構成される。
【００５９】
この解除レバー５０’は、縦溝１７を通してレバー部５７の先端部がボディ２の外に露出された状態で、端子部収納室１４ｂの底部の軸受け台１８に軸部５１が載置される。そして、端子部収納室１４ｂに解除レバー５０を収納した後に、導電部材４０ａ，４０ｂを収納凹部１４に収納すると、解除レバー５０’の上側から端子板２１が挿入され、解除レバー５０’の押動部５６が、端子板２１の鎖錠片２３，２３における受け部２３ｃ，２３ｃと当接する。また、端子板２１の一部を切り起こして形成した押え片２４が、軸部５１における軸受け台１８と反対側の周面と当接することで、解除レバー５０’が軸部５１を支点に回動自在に枢支される（図２６参照）。
【００６０】
ここで、本実施形態では軸部５１の回動中心Ｏから操作部５７の操作点Ａまでの距離ａと、回動中心Ｏから押動部５６による鎖錠部２３ａの押圧点Ｂまでの距離ｂとの比率（梃子比ａ：ｂ）をできるだけ大きくとることで、てこの原理を用いて解除レバー５０’の操作力を低減している。また、実施形態１の解除レバー５０のように支点となる軸部５１が押動部５３と操作部５４の間に位置する場合は、図１８（ａ）（ｂ）に示すように解除操作時に押動部５３が右斜め上方へ移動するのに対して操作部５４が左斜め上方へ移動するというように、変位の方向が異なるために無駄な動きが生じるが、本実施形態では操作点Ａと押圧点Ｂとを略同じ高さとし、支点となる軸部５１と操作部５７との間に押動部５３を配置させているので、鎖錠部２３ａが変位する方向と操作部５７が変位する方向とが略同じ方向になる。したがって、解除レバー５０’の操作部５７は、鎖錠部２３ａの変位をそのまま追いかけるように回転するから、解除レバー５０’の動きに無駄がなくなり、鎖錠部２３ａを確実に押圧することができる。また、端子板２１の一部を切り起こして形成した押え片２４で軸部５１を前側（図２６の上側）から押さえることによって、解除レバー５０’の回動支点となる軸部５１を安定して軸支することができ、そのうえ端子板２１における鎖錠片２３以外の部位（端子板２１の下部）を切り起こして押え片２４を形成しているので、鎖錠部２３ａの変位に影響を与えることもない。
【００６１】
ところで、押動部５６と操作部５７とを略同じ高さとした場合は、レバー回転時に操作部５７が入り込む逃がし溝を端子板２１に形成する必要があり、その結果、端子板２１の強度が低下する虞がある。そこで、図２７及び図２８に示すように、押動部５６を操作部５７よりも前方（図中の上方）へ突出させるとともに、端子板２１の接触片２２における中央片２１ａとの連結部２１ｂを幅広に形成しても良い。すなわち、押動部５６を操作部５７よりも連結部２１ｂ側に突出させることで、レバー回転時に操作部５７が連結部２１ｂに干渉するのを防止でき、押動部５７と操作部５７とを略同じ高さとした場合に比べて連結部２１ｂの幅を幅広に形成できるから、端子板２１の強度を十分に確保できる。尚、図２７（ｂ）に示すように、解除レバー５０’の連結部５５は端子板２１の隣接する鎖錠片２３，２３の間に配置されている。
【００６２】
また、本実施形態の解除レバー５０’は電圧極側の端子部２０から電線を外すために用いられるものであるが、この解除レバー５０’を接地極側の端子部２０に用いても良く、その場合は図２９及び図３０に示すように操作部５７の側面視の形状を略Ｌ字形に形成して、この操作部５７をボディ２の底面に設けた凹部２ｇの貫通孔２ｆから突出させるように配置する。
【００６３】
この解除レバー５０’は、凹部２ｇの底部に設けた貫通孔２ｆを通してレバー部５７の先端部がボディ２の外に露出された状態で、端子部収納室１２ｂの底部に設けられた軸受け台１８に軸部５１が載置される。そして、端子部収納室１２ｂに解除レバー５０’を収納した後に、導電部材４０ｃを収納凹部１２に収納すると、解除レバー５０’の上側から端子板２１が挿入され、解除レバー５０’の押動部５６が、端子板２１の鎖錠片２３における受け部２３ｃと当接する。また、端子板２１の一部を切り起こして形成した押え片２４が、軸部５１における軸受け台１８と反対側の周面と当接することで、解除レバー５０’が軸部５１を支点に回動自在に枢支される（図３０参照）。また、解除レバー５０’の連結部５５は端子板２１の隣接する鎖錠片２３，２３の間に配置されている（図２９（ｂ）参照）。
【００６４】
そして、この解除レバー５０’では軸部５１の回動中心Ｏから操作部５７の操作点Ａまでの距離ａと、回動中心Ｏから押動部５６による鎖錠部２３ａの押圧点Ｂまでの距離ｂとの比率（梃子比ａ：ｂ）をできるだけ大きくとることで、てこの原理を用いて解除レバー５０’の操作力を低減している。また、電圧極側の解除レバー５０’では操作部５７の先端位置をボディ２の表面から後退した位置に配置するために、操作部５７の大きさに制約があるが、接地極側の解除レバー５０’ではボディ２の中央に凹部２ｇを設け、この凹部２ｇに貫設した貫通孔２ｆから操作部５７を突出させているので、操作部５７を大きくすることで、電圧極側に比べて梃子比を大きくとることができ、鎖錠部２３ａを解除するのに必要な力をさらに低減できるという効果がある。
【００６５】
（実施形態３）
図３１に本実施形態の速結端子装置に用いる電圧極側の解除レバー６０ａの外観斜視図を、図３２（ａ）（ｂ）に解除レバー６０ａを器体１に組み込んだ状態の断面図をそれぞれ示す。また図３５に接地極側の解除レバー６０ｂの外観斜視図を、図３６（ａ）（ｂ）に解除レバー６０ｂを器体１に組み込んだ状態の断面図をそれぞれ示す。尚、解除レバー６０ａ，６０ｂ以外は実施形態１と略同様であるので、共通する構成要素には同一の符号を付して、その説明は省略する。
【００６６】
先ず電圧極側の解除レバー６０ａについて説明する。解除レバー６０ａは合成樹脂成型品からなり、ボディ２及びカバー３の側壁の対向面に形成した軸受け台３ｆに回転自在に軸支される円柱状の軸部６１と、軸部６１の周面から後方（図３１中の下方）に突出する連結片６２と、連結片６２の下部に突設された押動部６３と、押動部６３の下側部略中央から下方に突出する幅細の操作部６４とを一体に形成して構成される。
【００６７】
一方、ボディ２の端子部収納室１４ｂの底部には、操作部６４を挿通させる貫通孔２ｊが形成されており、解除レバー６０ａは、貫通孔２ｊを通して操作部６４の先端部をボディ２の外に露出させるとともに、軸部６１を膨出部２ａの側壁の前縁に設けた軸受け台（図示せず）に載置した状態で、端子部収納室１４ｂ内に配置される（図３３参照）。端子部収納室１４ｂに解除レバー６０ａを収納した後に、導電部材４０ａ，４０ｂを収納凹部１４に収納すると、解除レバー６０ａの上側から端子板２１が挿入され、解除レバー６０の押動部６３が、端子板２１の鎖錠片２３，２３における受け部２３ｃ，２３ｃと当接する。そして、ボディ２の開口面にカバー３を突き合わせた状態では、カバー３の開口縁に設けた軸受け台３ｆに軸部６１が摺接することによって、解除レバー６０ａがボディ２とカバー３との間で回動自在に枢支される。なお、膨出部２ａの縦溝１７は閉塞されている。
【００６８】
而して、端子部２０から電線を外す際には、器体１を持った一方の手でボディ２の貫通孔２ｊから露出する操作部６４を図３２（ａ）中の右側に押すと、軸部６１を支点に解除レバー６０ａが図中反時計回りに回転し（図３２（ｂ）参照）、押動部６３が鎖錠片２３の受け部２３ｃを押圧することによって、電線に食い込んでいる鎖錠部２３ａを接触片２２（電線）から離れる向きに撓ませるので、他方の手で電線挿入孔１５から電線を引き抜くことができ、従来に比較して電線の取り外し作業が容易に行え、且つ２本の電線の取り外し作業を一度に行うことができる。その後、操作部６４を押す力を無くすと、解除レバー６０ａは鎖錠片２３のばね力によって初期位置まで回転する。尚、図３２（ｂ）では図示を簡単にするために端子板２１を省略して図示してある。
【００６９】
ここで、本実施形態では、図３３に示すように隣接する電線挿入孔１５，１５の間に解除レバー５０の移動代を設けているので、操作部６４の幅を細くする必要があるが、回動中心Ｏから操作部６４の操作点Ａまでの距離ａと、回動中心Ｏから押動部６３による鎖錠部２３ａの押圧点Ｂまでの距離ｂとの比率（梃子比ａ：ｂ）をできるだけ大きくとることで、てこの原理を用いて、より少ない操作力で鎖錠部２３ａを解除することができる。
【００７０】
また、本実施形態ではボディ２とカバー３との対向面に設けた軸受け台で軸部６１を挟持することによって、解除レバー６０ａを回動自在に軸支しているが、ボディ２又はカバー３の何れかに解除レバー６０ａを枢支する枢支手段を設けても良く、例えば図３４（ａ）に示すように、膨出部２ａの側壁の開口縁略中央に係止片１９を設け、軸部６１の両端部を側壁の開口縁に設けた軸受け台（図示せず）に載置するとともに、軸部６１の中央部に係止片１９の先端の爪１９ａを係止させることで、解除レバー６０ａをボディ２に回動自在に軸支させるようにしても良い（図３４（ｂ）参照）。尚、係止片１９の両側には凹溝１９ｂを形成してあるので、係止片１９が撓みやすくなっている。
【００７１】
次に、接地極側の解除レバー６０ｂについて説明する。解除レバー６０ｂは合成樹脂成型品からなり、短冊状の操作部６５と、操作部６５の一端部から二股に分かれた連結部６２と直方体状の押動部６３とで側面視の形状が略Ｙ字状に形成されており、連結部６２の先端部の両側縁からは回動軸６１，６１が側方に向かってそれぞれ突出している。
【００７２】
一方、ボディ２の収納凹部１２の底部には、操作部６５を挿通させる貫通孔２ｆが形成されており、解除レバー６０ｂは、貫通孔２ｆを通して操作部６５の先端部がボディ２の外に露出された状態で（図３６（ａ）参照）、ボディ２の底部から立設された軸受け台２７に回動自在に載置される。収納凹部１２に解除レバー６０ｂを収納した後に、導電部材４０ｃを収納凹部１２に収納すると、解除レバー６０ｂの上側から端子板２１が挿入され、解除レバー６０ｂの押動部６３が、端子板２１の鎖錠片２３における受け部２３ｃと当接する。そして、ボディ２の開口面にカバー３を突き合わせた状態では、カバー３の前壁の裏面に立設されたリブ（図示せず）と軸受け台２７との間で軸部６１が挟持され、解除レバー６０’が回動自在に軸支される。
【００７３】
ここで、解除レバー６０ｂには一対の軸部６１，６１の間の部位に切欠溝６２ａ（逃がし部）が形成されているので、解除レバー６０ｂの上側に配置される刃受部材４０ｃの連結片３２ｃを切欠溝６２ａに通すことで、この連結片３２ｃと解除レバー６０ｂとが干渉するのを防止できる。
【００７４】
また、接地極側の解除レバー６０ｂは、ボディ２底部の凹部２ｇに設けた貫通孔２ｆから操作部６５を露出させており、電圧極側の解除レバー６０ａの操作部６４を挿通させる貫通孔２ｊに比べて貫通孔２ｆの幅を大きくとることができるから、操作部６５の幅を広げて、解除操作時に手に加わる圧力を低減でき、より大きな力を加えることができる。
【００７５】
また、本実施形態では解除レバー６０ｂの操作部６５が凹部２ｇの底面から浮いた状態で配設されるので、施工時に器体１の周りに配置される電線などによって操作部６５に外力が加わって、解除レバー６０ｂが変形する虞があるが、図３６及び図３７に示すように、ボディ２底部の凹部２ｇにおける貫通孔２ｆの周縁部に、非操作状態において操作部６５と当接する変形防止用のリブ２８を突設しているので、操作部６５に加わる外力をリブ２８で受けることができ、解除レバー６０ｂの変形を防止できる。
【００７６】
（実施形態４）
本発明の実施形態４について図３８〜図４１を参照して説明を行う。本実施形態では、実施形態１の速結端子装置において、解除レバー５０の代わりに軸部と同心の円周面に操作部を設けた回転体からなるダイヤル式の解除釦７０ａ，７０ｂを用いている。尚、解除釦７０ａ，７０ｂ以外は実施形態１と略同様であるので、共通する構成要素には同一の符号を付して、その説明は省略する。
【００７７】
先ず電圧極側の解除釦７０ａについて図３８及び図３９を参照して説明を行う。解除釦７０ａは合成樹脂成型品からなり、円盤の一部を切り欠くことによって側面視の形状が略三日月形に形成され、器体１の開口１ａから円周面を露出させた操作部７２と、操作部７２の円周面と同心の円周面７１ａを有し、操作部７２における円周面と対向する面に突設された軸部７１と、操作部７２の軸部７１が突設された面に軸部７１と並べて突設された押動部７３とを一体に形成して構成される。ここで、操作部７２には、端子板２１の中央片２１ａから延設された円弧状の引掛片２１ｃに軸部７１の円周面７１ａを当接させた状態で、端子板２１の中央片２１ａ及び接触片２２を逃がすための切欠部７２ａが形成され、さらに円周面の一部には手の指を引っ掛けるための引掛部７２ｂが形成されている。
【００７８】
この解除釦７０ａは、軸部７１の円周面７１ａを端子板２１の円弧状の引掛片２１ｃに当接させた状態で、軸部７１を引掛片２１ｃに引っ掛けることで、端子板２１に対して回動自在に軸支されており、解除釦７０ａの押動部７３が鎖錠片２３，２３の受け部２３ｃ，２３ｃに対向して配置される。なお、ボディ２の端子部収納室１４ｂの側壁の前端面には、解除釦７０ｂの操作部７２を逃がすための凹溝２ｋが形成されている。
【００７９】
而して、端子部２０から電線を外す際には、器体１を持った手の指で開口１ａから露出する操作部７２の引掛部７２ｂを図３９（ａ）中の下側に押圧すると、解除釦７０ｂが軸部７１を中心に図中反時計回りに回転し（図３９（ｂ）参照）、押動部７３が鎖錠片２３の受け部２３ｃを押圧することによって、電線に食い込んでいる鎖錠部２３ａを接触片２２（電線）から離れる向きに撓ませるので、他方の手で電線挿入孔１５から電線を引き抜くことができ、従来に比べて電線の引き抜き作業を容易に行える。その後、操作部７２の引掛部７２ｂを押す力を無くすと、解除釦７０ｂは鎖錠片２３のばね力によって初期位置まで回転する。
【００８０】
このように、本実施形態では、レバー形の解除手段の代わりに軸部７１と同心の円周面に操作部７２を設けた回転体からなるダイヤル式の解除釦７０ａを用いているので、図３９に示すように、上述の各実施形態のように解除手段を納めるための大きな穴をボディ２に形成する必要がなく、ボディ２の剛性を高めることができる。また本実施形態においても軸部７１の中心（回動中心）から操作部７２の操作点までの距離と、回動中心から押動部７３による鎖錠部２３ａの押圧点までの距離との比率（梃子比）をできるだけ大きくとることで、てこの原理を用いて、より少ない操作力で鎖錠部２３ａを解除することができる。
【００８１】
次に接地極側の解除釦７０ｂについて説明する。解除釦７０ｂは合成樹脂成型品からなり、側面視の形状が略三日月形に形成された操作部７２と、操作部７２の円周面から斜め下向きに突出し、器体１底面の凹部２ｇに設けた貫通孔２ｆから外側に露出させる棒状のレバー部７２ｃと、操作部７２の円周面と同心の円周面７１ａを有し、操作部７２における円周面と対向する面に突設された軸部７１と、操作部７２の軸部７１が突設された面に軸部７１と並べて突設された押動部７３とを一体に形成して構成される。ここで、操作部７２には、軸部７１の円周面７１ａを端子板２１の引掛片２１ｃに当接させた状態で、端子板２１の中央片２１ａ及び接触片２２を逃がすための切欠部７２ａが形成されている。
【００８２】
この解除釦７０ｂは、軸部７１の円周面７１ａを端子板２１の円弧状の引掛片２１ｃに当接させた状態で、軸部７１を引掛片２１ｃに引っ掛けることで、端子板２１に対して回動自在に軸支されており、解除釦７０ｂの押動部７３が鎖錠片２３の受け部２３ｃに対向して配置される。なお、解除釦７０ｂのレバー部７２ｃはボディ２の底壁の貫通孔２ｆから外側に突出している。
【００８３】
而して、端子部２０’から電線を外す際には、器体１を持った一方の手の指で、ボディ２の貫通孔２ｆから露出する操作部７２のレバー部７２ｃを図４１（ａ）中の上側に押圧すると、解除釦７０ｂが軸部７１を中心に図中反時計回りに回転し（図４１（ｂ）参照）、押動部７３が鎖錠片２３の受け部２３ｃを押圧することによって、電線に食い込んでいる鎖錠部２３ａを接触片２２（電線）から離れる向きに撓ませるので、他方の手で電線挿入孔１５から電線を引き抜くことができ、従来に比べて電線の引外し作業が容易に行える。その後、操作部７２のレバー部７２ｃを押す力を無くすと、解除釦７０ｂは鎖錠片３のばね力によって復帰位置まで回転する。
【００８４】
【発明の効果】
上述のように、請求項１の発明は、配線器具の器体の底面に貫設した電線挿入孔を通して器体に導入される電線に接触する複数の端子板と、それぞればね力を利用して端子板との間で電線を狭持するとともに鎖錠部が該電線に食い込んで抜け止めする複数の電線接続手段と、２個の鎖錠部に対して１つ設けられ、２個の鎖錠部による抜け止め状態を一度に解除する解除手段とを備え、電線接続手段は端子板と一体に形成され、端子板は、ばね性を有する金属板の両端部を重なり合うように対向して折り曲げることによって、主片の一端側から器体の底面側に垂下した接触片と、主片の他端側から器体の底面側に垂下したＪ形の鎖錠片とが設けられるとともに、接触片には電線に弾接する平坦な接触部と、電線の挿入方向に沿った接触部の両側において電線を押圧する一対の押圧部が設けられ、鎖錠片には、電線を接触部側へ押圧するとともに電線の一部に食い込んで抜け止めする鎖錠部が先端に設けられ、接触片が設けられた端子板の一方の端部と鎖錠片が設けられた端子板の他方の端部とが、器体内に導入される電線から離れる向きに撓み可能であり且つ接触部の電線挿入孔から遠い側の先端部よりも電線挿入孔に近い側の後端部が電線に近付く向きに傾斜するように端子板が器体内に収納されてなり、解除手段は、器体の表面に露出して手動操作される操作部と、器体内に枢支されて該操作部を回動自在とする軸部と、該軸部を支点に操作部が手動操作によって回動したときにばね力に抗して２個の鎖錠部を電線から引き離す向きに押し動かす押動部とを具備して成ることを特徴とし、器体を持った一方の手で操作部を操作すれば、電線に食い込んでいる２個の鎖錠部が押動部によって押し動かされて抜止状態が解除され、他方の手で電線挿入孔から電線を引き抜くことができ、従来に比較して電線の取り外し作業が容易に行え、且つ２本の電線の取り外し作業を一度に行うことができる。さらに、解除手段はてこの原理を使って押動部により鎖錠部を押し動かしているため、操作部にかかる荷重が低減でき、２個の鎖錠部を同時に押し動かす場合でもより小さな操作力で行うことができる。

And a substantially triangular shape that protrudes laterally from both side surfaces of one end portion in the circumferential direction of the support portion 52 and has one surface concentric with the shaft portion 51 and having a smaller diameter than the circumferential surface of the support portion 52. The columnar pushing portions 53 and 53 and the T-shaped operation portion 54 that obliquely protrudes from one end portion in the circumferential direction of the support portion 52 are integrally formed. In addition, the semicircle part 51a by the side of the bearing stand 18 in the shaft part 51 is formed in thickness compared with the remaining semicircle part, and rotational movement is made by making the part which contacts the bearing stand 18 thick. The strength of the semicircular portion 51a to which a load from the bearing base 18 is applied when performing the above is increased.
[0039]
The release lever 50 is configured such that the distal end portion of the operation portion 54 is exposed to the outside of the body 2 through the vertical groove 17, and the shaft portion 51 is placed on the bearing base 18 provided at the bottom portion of the terminal portion storage chamber 14 b. The circumferential surface of the support portion 52 is brought into contact with the inner wall of the bulging portion 2a (body 2), so that the shaft portion 51 is pivotally disposed along the front-rear direction of the container body 1 (see FIG. (See FIGS. 18A and 18B). After the release lever 50 is stored in the terminal portion storage chamber 14b, the pair of blade receiving portions 30, 31 are fixed to the terminal plate 21 and the connecting pieces 25, 25 of the terminal plate 21 so that they are adjacent to each other. When the conductive members 40 a, 40 b comprising the blade receiving portions 30, 31 are stored in the storage recess 14 of the body 2, the pushing portions 53, 53 of the release lever 50 are received by the locking pieces 23, 23 of the terminal plate 21. It contacts the portions 23c and 23c (see FIGS. 17 and 18).
[0040]
Next, the conductive member 40c and the release lever 50 housed in the housing recess 12 of the body 2 will be described. As shown in FIGS. 1 and 13, the conductive member 40 c is configured by integrally connecting the terminal plate 21 ′ and the blade receiving portion 32, and the terminal plate 20 ′ and the release lever 50 form the terminal portion 20 on the grounding pole side. '(Quick connection terminal device) is configured.
[0041]
The blade receiving part 32 is a pair of blades for plug blades that are provided so as to protrude from the tip edges of both side pieces of the base 32b and to be opposed to each other by processing a metal plate having a spring property. The receiving spring 32a is formed in an L shape in a side view, and a connecting piece 32c that extends continuously and integrally from the central piece of the base 32b and is caulked and fixed to the central piece 21a of the terminal plate 21 'is formed integrally. It is. Further, since the terminal plate 21 ′ has the same structure as the terminal plate 21 of the terminal portion 20 except that the connecting piece 25 is eliminated, common constituent elements are denoted by the same reference numerals, and description thereof is made. Is omitted.
[0042]
Since the release lever 50 has the same shape and the same size as the release lever 50 of the terminal portion 20, the description thereof is omitted. In the release lever 50, the distal end portion of the operation portion 54 is exposed to the outside of the body 2 through the through hole 2f provided in the bottom portion of the concave portion 12, and the shaft portion 51 is attached to the bearing base 18 provided in the bottom portion of the terminal portion storage chamber 12b. By mounting, it arrange | positions rotatably along the front-back direction of the container 1 by using the axial part 51 as a fulcrum. Then, after the release lever 50 is stored in the terminal storage chamber 12b, the conductive member 40c including the terminal plate 21 ′ and the blade receiving portion 32 fixed to the central piece 21a of the terminal plate 21 ′ is stored in the storage recess 12. The pushing portions 53, 53 of the release lever 50 come into contact with the receiving portions 23c, 23c of the locking pieces 23, 23 of the terminal plate 21 ′.
[0043]
And when connecting an electric wire to the above terminal parts 20 and 20 ', if an electric wire is inserted between the contact piece 22 and the locking piece 23 of the terminal plates 21 and 21' through the electric wire insertion hole 15, a chain | strand will be obtained. When the lock portion 23a of the lock piece 23 bites into the electric wire, the electric wire is prevented from coming off, and the electric wire elastically contacts the contact portion 22a of the contact piece 22 by the spring force of the lock piece 23, and the electric wire further includes a pair of pressing portions. Since it is pressed toward the locking piece 23 by 22b, 22c, the locking portion 23a and the pressing force of the pressing portions 22b, 22c are balanced and the electric wire is clamped. That is, the terminal portions 20, 20 ′ are fast connection terminals that can be connected simply by inserting an electric wire into the electric wire insertion hole 15. Here, the wire connecting means is constituted by the locking pieces 23, and the terminal plates 21 and 21 'are formed by integrally connecting the contact pieces 22 and the locking pieces 23 as terminal boards.
[0044]
On the other hand, when the electric wires are removed from the terminal portions 20 and 20 ′, the operating portion 54 exposed from the longitudinal groove 17 or the through hole 2 f of the body 2 is pushed to the front side of the body 1 with one hand holding the body 1. Then, the release lever 50 rotates around the shaft portion 51a, and the pushing portion 53 presses the receiving portion 23c of the locking piece 23, so that the locking portion 23a biting into the electric wire is removed from the contact piece 22 (electric wire). ), The electric wire can be pulled out from the electric wire insertion hole 15 with the other hand, and the electric wire can be removed more easily than in the prior art. Thereafter, when the force for pressing the operation portion 54 is removed, the release lever 50 is rotated to the initial position by the spring force of the locking piece 23.
[0045]
In this embodiment, since the pair of pushing portions 53 are provided on both side surfaces of the support portion 52, the two locking pieces 23 are bent at the same time by the release lever 50, and the two electric wires are simultaneously sent. Can be pulled out. In addition, since the two locking pieces 23 are bent at the same time, an operation force about twice as large as that required when the single locking piece 23 is bent is required. However, the release lever 50 uses the lever principle. Since the lock piece 23 is pushed and moved by the pushing portion 53, the load applied to the operation portion 54 can be reduced. In addition, since the shaft portion 51 serving as a rotation fulcrum is arranged inside the locking piece 23, the distance a from the rotation center O of the shaft portion 51 to the operation point A of the operation portion 54, and the rotation center O The ratio (the lever ratio a: b) to the distance b from the pressing portion 53 to the pressing point B of the locking portion 23a can be made as large as possible, and the locking is performed with the smallest possible operating force by increasing the lever ratio. The part 23a can be bent.
[0046]
Incidentally, in order to rotatably support the release lever 50, it is necessary to place the circumferential surface of the shaft portion 51a on the bearing base 18 and to support the release lever 50 from another direction (front or side). In this embodiment, the circumferential surface of the pushing portion 53 (first pressing portion) is swollen at the non-release operation position (position when the release operation is not performed) shown in FIG. The circumferential surface of the support portion 52 (second pressing portion) is centered on the terminal plate 21 at the release operation position (rotation position) shown in FIG. 18B. The release lever 50 is supported from the front by abutting against the piece 21a. In order to pivotally support the release lever 50 by sandwiching the circumferential surface of the shaft portion 51 with the bearing base 18, a member for pressing the circumferential surface of the shaft portion 51 from the front is separately required. In the embodiment, as the release lever 50 is rotated, the portion that holds the release lever 50 is shifted from the circumferential surface of the pushing portion 53 to the circumferential surface of the support portion 52, so that a separate member is added. The release lever 50 can be pivotally supported by the central piece 21a of the terminal board 21 or the like.
[0047]
Further, when the operation portion 54 of the release lever 50 for the voltage electrode protrudes outside the surface of the bulging portion 2a except during the release operation, the protruding portion of the operation portion 54 becomes an obstacle when the container 1 is constructed. However, in this embodiment, the distal end position of the operation portion 54 is the position of the bulging portion 2a at the time of the non-release operation, although an electric wire or the like disposed around the container body 1 may hit the operation portion 54 and come off. Since the release lever 50 is disposed so as to be in a position retracted from the surface (see FIG. 17), there is no portion protruding outward from the surface of the body 2, which may obstruct the construction of the body 1, It can prevent that the electric wire etc. which are arrange | positioned around the body 1 contact | win the operation part 54, and an electric wire remove | deviates. Further, since the through hole 2f through which the operation part 54 of the release lever 50 for the ground electrode is inserted is formed at the bottom of the recess 2g formed on the rear surface of the body 2, as shown in FIGS. The distal end of the operation unit 54 does not protrude outward from the rear surface of the body 2, and it is only necessary to push the distal end of the operation unit 54 down to the bottom side of the recess 2g during the release operation. Since the recess 2g is provided in this way and the operation portion 54 of the release lever 50 is exposed from the through hole 2f at the bottom of the recess 2g, the positional relationship between the release lever 50 and the terminal plates 21 and 21 ′ in the initial state is determined. With the same positional relationship between the voltage electrode side and the ground electrode side, the release lever 50 can be shared between the voltage electrode side and the ground electrode side. As a result, the investment required for development and manufacturing can be suppressed, The effect that quality control becomes easy by reducing the kind of parts is acquired.
[0048]
As shown in FIG. 20, the surface of the bulging portion 2a is provided with a concave portion 17b recessed in an arc shape at a portion facing the operation portion 54, and further, a portion facing the operation portion 54 on the inner side surface of the recess 2g. Further, since the concave portion 17b that is recessed in an arc shape is formed, it is easy to put a finger between the concave portion 17b and the operation portion 54, and the operation portion 54 can be easily pulled out when releasing the electric wire.
[0049]
In this embodiment, a triangular prism-shaped operation piece 54a extending in a direction orthogonal to the operation unit 54 is projected from the distal end of the operation unit 54, and the release lever is operated by operating the operation piece 54a. However, when the release lever 50 is returned to the initial position, the positional relationship is set such that both side edges of the operation piece 54a are rubbed at the corners of the step portions 17a, 17a and the groove 17b. It is. Therefore, when the release lever 50 is returned to the non-release operation position, both side edges of the operation piece 54a hit the corners of the stepped portion 17a and the recess 17b and the operation portion 54 bends. Since the release lever 50 is temporarily fixed at the initial position by getting over, it is possible to prevent the release lever 50 from inadvertently moving and releasing the locked state of the electric wire. Here, a holding means for temporarily holding the release lever 50 is configured by the corner portion formed by the step portion 17 a and the concave portion 17 b and the operation piece 54 a of the operation portion 54.
[0050]
If the tip of the operation piece 54a is thin, the pressure applied to the hand increases and the hand becomes painful. As shown in FIG. 24, the operation piece 54b having a larger width than the operation piece 54a of FIG. The inner surface (opposite surface facing the side wall of the body 2) 54c of the operation piece 54b is preferably rounded in order to insert a finger during the release operation.
[0051]
By the way, the conductive members 40a and 40b configured as described above store the blade receiving portions 30 and 31 in the blade receiving portion storage chambers 14a provided at the four corners of the body 2, and the terminal plate 21 in the terminal portion storage chamber 14b. Is stored in each storage recess 14 of the body 2. In addition, the partition 16 which partitions both the storage chambers 14a and 14b is provided with a slit 16a for inserting the connecting pieces 25 and 25 of the terminal plate 21. The conductive member 40c is housed in the housing recess 12 so that the blade receiving portion 32 is housed in the blade receiving portion housing chamber 12a of the body 2 and the terminal plate 21 'is housed in the terminal portion housing chamber 12b. In a state where the cover 3 is abutted against the opening surface of the body 2, the blade receiving portion 30 and the contact insertion port 6 of the universal outlet 5 provided on the front wall of the cover 3 face each other, and the blade receiving portion 31 and 32 and the contact insertion ports 8b and 8a of the three-pole outlet port 7 face each other.
[0052]
Here, when a cylindrical conductive pin is inserted between a pair of blade receiving springs 30a facing from the contact insertion port 6, the conductive pins are elastically sandwiched between the pair of blade receiving springs 30a, and the conductive member When the flat blades are inserted between the side edges of the pair of blade receiving springs 30a and the blade receiving springs 30b, the side surfaces of the pair of blade receiving springs 30a are electrically connected. The plug blade is elastically sandwiched between the edge and the blade receiving spring 30b, and the conductive members 40a, 40b and the plug blade are electrically connected. When a flat plug blade is inserted between the contact insertion port 8 and the pair of blade receiving springs 31a, the plug blade is elastically held between the pair of blade receiving springs 31a, and the conductive members 40a and 40b. The blade is electrically connected. When a flat plug blade is inserted between the pair of blade receiving springs 32a facing from the contact insertion port 8a, the plug blade is elastically sandwiched between the pair of blade receiving springs 32a, and the conductive member 40c and the plug are plugged. The blade is electrically connected. Here, the pair of blade receiving springs 30a of the blade receiving part 30, the pair of blade receiving springs 31a of the blade receiving part 31, and the pair of blade receiving springs 32a of the blade receiving part 32 are opposed to each other as the distance between them becomes more forward. It is inclined so as to be narrower, and the front end is inclined so that the distance between the front ends is increased so that the conductive pin or the plug blade can be easily inserted, so that the conductive pin or the plug blade can be easily inserted. The blade receiving spring 30b of the blade receiving portion 30 is also inclined so that the distance from the blade receiving spring 30a is narrower toward the front, and the distance between the front ends is increased toward the front so that the plug blade can be easily inserted. It is inclined so that the plug blade can be easily inserted.
[0053]
Next, a structure in which the body 1 is assembled by joining the body 2 and the cover 3 will be described. In this embodiment, the body 1 is assembled by joining the body 2 and the cover 3 by fitting the assembly frame 4 to the fitting protrusions 2b and 3c provided on both the body 2 and the cover 3 so as to be uneven. It has become.
[0054]
On both side surfaces along the longitudinal direction of the body 2, prismatic fitting protrusions 2 b project from both sides of the bulging portion 2 a, and further concave on the front side of the fitting protrusion 2 b (left side in FIG. 5B). A groove 2c is formed. Further, on both side surfaces along the longitudinal direction of the cover 3, fitting projections 3 c having the same shape and the same dimensions as the fitting projections 2 b are provided on both side portions of the shoulder portion 3 b, and the cover is provided on the opening surface of the body 2. In a state where the three are abutted, the respective fitting protrusions 2b and 3c are arranged in a line in the front-rear direction across the concave groove 2c.
[0055]
On the other hand, the assembly frame 4 is made of a synthetic resin molded product having elasticity. As shown in FIGS. 9A to 9C, the fitting holes 4b and 4b for fitting with the fitting protrusions 2b and 3c are provided in the longitudinal direction. It has strip-like vertical pieces 4a arranged side by side, and has a locking claw 4d at the tip from the substantially central portion sandwiched between the fitting holes 4b and 4b on the back side of the vertical piece 4a facing the container 1. The locking protrusion 4c protrudes backward. Further, on the front end surface of the vertical piece 4a, a mounting plate for embedding and arranging an embedded wiring device on the construction surface or a flash plate having a wiring device mounting structure (hereinafter simply referred to as "plate"). A mounting claw 4e for mounting the container 1 to the mounting frame or the plate frame by engaging with the engaging hole provided in FIG.

And the cover 3 are combined.
[0057]
(Embodiment 2)
FIG. 25 shows a side view of a release lever 50 ′ used in the quick connection terminal device of this embodiment, and FIG. 26 shows a side view of the release lever 50 ′ incorporated in the terminal plate 21. The release lever 50 'is for removing the electric wire from the voltage electrode side terminal portion 20, and is the same as that of the first embodiment except for the release electrode 50' on the voltage electrode side. A reference numeral is attached and the description thereof is omitted.
[0058]
The release lever 50 ′ is made of a synthetic resin molded product, and is formed with a cylindrical shaft portion 51 that is slidably mounted on a bearing base 18 provided on the body 2, and a side view shape that is substantially L-shaped. A connecting portion 55 that protrudes outward from a circumferential surface other than the sliding contact portion with the bearing base 18 in the shaft portion 51, and a pushing portion 56 that protrudes from both side surfaces of the distal end portion of the vertical piece 55 b of the connecting portion 55. And a T-shaped lever portion 57 that protrudes from the distal end portion of the connecting portion 55 in a direction substantially parallel to the horizontal piece 55a of the connecting portion 55.
[0059]
In the release lever 50 ′, the shaft portion 51 is placed on the bearing base 18 at the bottom of the terminal portion storage chamber 14 b with the distal end portion of the lever portion 57 exposed to the outside of the body 2 through the vertical groove 17. Then, after the release lever 50 is stored in the terminal portion storage chamber 14b, when the conductive members 40a and 40b are stored in the storage recess 14, the terminal plate 21 is inserted from above the release lever 50 ', and the release lever 50' is pushed. The portion 56 contacts the receiving portions 23 c and 23 c of the locking pieces 23 and 23 of the terminal plate 21. Further, the pressing piece 24 formed by cutting and raising a part of the terminal plate 21 abuts on the peripheral surface of the shaft portion 51 on the side opposite to the bearing base 18, so that the release lever 50 ′ rotates around the shaft portion 51 as a fulcrum. It is pivotally supported (see FIG. 26).
[0060]
Here, in the present embodiment, the distance a from the rotation center O of the shaft portion 51 to the operation point A of the operation portion 57 and the distance from the rotation center O to the pressing point B of the lock portion 23a by the pushing portion 56. By making the ratio (the lever ratio a: b) with b as large as possible, the operating force of the release lever 50 ′ is reduced using the lever principle. Further, when the shaft portion 51 serving as a fulcrum is located between the pushing portion 53 and the operation portion 54 as in the release lever 50 of the first embodiment, during the release operation as shown in FIGS. Although the pushing portion 53 moves obliquely upward to the right and the operation portion 54 moves obliquely upward to the left, useless movement occurs due to the different directions of displacement. And the pressing point B have substantially the same height, and the pressing portion 53 is disposed between the shaft portion 51 serving as a fulcrum and the operating portion 57, so the direction in which the locking portion 23a is displaced and the operating portion 57 are displaced. The direction to do is substantially the same direction. Accordingly, since the operation portion 57 of the release lever 50 ′ rotates so as to follow the displacement of the lock portion 23a as it is, the movement of the release lever 50 ′ is not wasted and the lock portion 23a can be reliably pressed. . Further, by pressing the shaft portion 51 from the front side (upper side in FIG. 26) with the presser piece 24 formed by cutting and raising a part of the terminal plate 21, the shaft portion 51 serving as the pivot point of the release lever 50 ′ is stabilized. In addition, since the presser piece 24 is formed by cutting and raising a portion of the terminal plate 21 other than the lock piece 23 (lower part of the terminal plate 21), the displacement of the lock portion 23a is affected. I will not give it.
[0061]
By the way, when the pushing part 56 and the operation part 57 are made substantially the same height, it is necessary to form a relief groove in the terminal plate 21 into which the operation part 57 enters when the lever rotates, and as a result, the strength of the terminal board 21 is increased. May decrease. Therefore, as shown in FIGS. 27 and 28, the pushing portion 56 protrudes forward (upward in the drawing) from the operation portion 57, and the connecting portion 21 b with the central piece 21 a of the contact piece 22 of the terminal plate 21. May be formed wide. That is, by causing the pushing portion 56 to protrude to the connecting portion 21b side from the operating portion 57, it is possible to prevent the operating portion 57 from interfering with the connecting portion 21b when the lever rotates, and the pushing portion 57 and the operating portion 57 are Compared to the case where the heights are substantially the same, the width of the connecting portion 21b can be formed wider, so that the strength of the terminal plate 21 can be sufficiently ensured. As shown in FIG. 27 (b), the connecting portion 55 of the release lever 50 ′ is disposed between the adjacent locking pieces 23, 23 of the terminal plate 21.
[0062]
Further, the release lever 50 ′ of the present embodiment is used to remove the electric wire from the voltage electrode side terminal portion 20, but the release lever 50 ′ may be used for the ground electrode side terminal portion 20. In this case, as shown in FIGS. 29 and 30, the shape of the operation portion 57 in a side view is formed in a substantially L shape, and the operation portion 57 is protruded from the through hole 2 f of the recess 2 g provided on the bottom surface of the body 2.

FIG. Each is shown. 35 is an external perspective view of the release lever 60b on the ground electrode side, and FIGS. 36 (a) and 36 (b) are cross-sectional views showing the state in which the release lever 60b is incorporated in the container body 1, respectively. The components other than the release levers 60a and 60b are substantially the same as those in the first embodiment. Therefore, common components are denoted by the same reference numerals, and description thereof is omitted.
[0066]
First, the release lever 60a on the voltage electrode side will be described. The release lever 60a is made of a synthetic resin molded product, and includes a cylindrical shaft portion 61 that is rotatably supported by a bearing base 3f formed on the opposing surfaces of the body 2 and the cover 3, and a peripheral surface of the shaft portion 61. A connecting piece 62 that protrudes rearward (downward in FIG. 31), a pushing portion 63 that projects from the lower portion of the connecting piece 62, and a narrow portion that protrudes downward from the approximate center of the lower portion of the pushing portion 63. The operation unit 64 is integrally formed.
[0067]
On the other hand, a through hole 2j through which the operation part 64 is inserted is formed at the bottom of the terminal part storage chamber 14b of the body 2, and the release lever 60a allows the distal end of the operation part 64 to be attached to the outside of the body 2 through the through hole 2j. The shaft portion 61 is placed in the terminal portion storage chamber 14b with the shaft portion 61 placed on a bearing base (not shown) provided on the front edge of the side wall of the bulging portion 2a (see FIG. 33). . After the release lever 60a is stored in the terminal portion storage chamber 14b, when the conductive members 40a and 40b are stored in the storage recess 14, the terminal plate 21 is inserted from above the release lever 60a, and the pushing portion 63 of the release lever 60 is It contacts the receiving portions 23c, 23c of the locking pieces 23, 23 of the terminal plate 21. In a state where the cover 3 is abutted against the opening surface of the body 2, the release lever 60 a is moved between the body 2 and the cover 3 by the shaft portion 61 slidingly contacting the bearing base 3 f provided at the opening edge of the cover 3. It is pivotally supported. In addition, the vertical groove 17 of the bulging part 2a is obstruct | occluded.
[0068]
Thus, when the electric wire is removed from the terminal portion 20, when the operating portion 64 exposed from the through hole 2j of the body 2 is pushed to the right side in FIG. The release lever 60a rotates counterclockwise in the drawing with the shaft portion 61 as a fulcrum (see FIG. 32 (b)), and the pushing portion 63 pushes the receiving portion 23c of the locking piece 23, thereby biting into the electric wire. Since the locking portion 23a is bent in a direction away from the contact piece 22 (electric wire), the electric wire can be pulled out from the electric wire insertion hole 15 with the other hand, and the electric wire can be easily detached compared to the conventional case. And the removal operation | work of two electric wires can be performed at once. Thereafter, when the force to push the operation portion 64 is removed, the release lever 60a is rotated to the initial position by the spring force of the locking piece 23. In FIG. 32 (b), the terminal plate 21 is omitted to simplify the illustration.
[0069]
Here, in this embodiment, as shown in FIG. 33, since the movement allowance of the release lever 50 is provided between the adjacent wire insertion holes 15, 15, it is necessary to reduce the width of the operation portion 64. Ratio of the distance a from the rotation center O to the operation point A of the operation unit 64 and the distance b from the rotation center O to the pressing point B of the lock portion 23a by the pressing unit 63 (the lever ratio a: b) By taking as large as possible, the locking portion 23a can be released with a smaller operating force using the lever principle.
[0070]
Further, in this embodiment, the release lever 60a is pivotally supported by holding the shaft portion 61 by a bearing base provided on the opposing surface of the body 2 and the cover 3, but the body 2 or the cover 3 is supported. For example, as shown in FIG. 34 (a), a locking piece 19 is provided at substantially the center of the opening edge of the side wall of the bulging portion 2a. By placing both ends of the shaft portion 61 on a bearing base (not shown) provided at the opening edge of the side wall, and locking the claw 19a at the tip of the locking piece 19 to the center portion of the shaft portion 61, The release lever 60a may be pivotally supported on the body 2 (see FIG. 34B). In addition, since the recessed groove 19b is formed in the both sides of the latching piece 19, the latching piece 19 becomes easy to bend.
[0071]
Next, the release lever 60b on the ground electrode side will be described. The release lever 60b is made of a synthetic resin molded product, and has a strip-like operation part 65, a connecting part 62 that is divided into two forks from one end of the operation part 65, and a rectangular parallelepiped pushing part 63, and the shape in a side view is substantially Y. The rotary shafts 61 and 61 protrude from the both side edges of the distal end portion of the connecting portion 62 toward the side.
[0072]
On the other hand, a through hole 2f through which the operation part 65 is inserted is formed at the bottom of the housing recess 12 of the body 2, and the release lever 60b is exposed to the outside of the body 2 through the through hole 2f. In this state (see FIG. 36 (a)), the body 2 is rotatably mounted on a bearing base 27 standing from the bottom of the body 2. After the release lever 60 b is stored in the storage recess 12, when the conductive member 40 c is stored in the storage recess 12, the terminal plate 21 is inserted from the upper side of the release lever 60 b, and the pushing portion 63 of the release lever 60 b is connected to the terminal plate 21. It abuts on the receiving portion 23c of the locking piece 23. When the cover 3 is abutted against the opening surface of the body 2, the shaft portion 61 is sandwiched between the rib (not shown) standing on the back surface of the front wall of the cover 3 and the bearing base 27 and released. The lever 60 'is pivotally supported so as to be rotatable.
[0073]
Here, since the notch groove 62a (relief part) is formed in the site | part between a pair of axial parts 61 and 61 in the cancellation | release lever 60b, it is a connection piece of the blade receiving member 40c arrange | positioned above the cancellation | release lever 60b. By passing 32c through the notch groove 62a, it is possible to prevent the coupling piece 32c and the release lever 60b from interfering with each other.
[0074]
Further, the release lever 60b on the ground electrode side exposes the operation portion 65 from the through hole 2f provided in the recess 2g on the bottom of the body 2, and the through hole 2j through which the operation portion 64 of the release lever 60a on the voltage electrode side is inserted. Since the width of the through hole 2f can be made larger than that, the width of the operation portion 65 can be widened to reduce the pressure applied to the hand during the release operation, and a larger force can be applied.
[0075]
In the present embodiment, since the operation portion 65 of the release lever 60b is disposed in a state of floating from the bottom surface of the recess 2g, an external force is applied to the operation portion 65 by an electric wire or the like disposed around the container body 1 during construction. The release lever 60b may be deformed, but as shown in FIGS. 36 and 37, the deformation prevention that abuts the operating portion 65 in the non-operating state on the peripheral portion of the through hole 2f in the recess 2g at the bottom of the body 2 is possible. Therefore, the external force applied to the operation portion 65 can be received by the rib 28, and deformation of the release lever 60b can be prevented.
[0076]
(Embodiment 4)
A fourth embodiment of the present invention will be described with reference to FIGS. In this embodiment, instead of the release lever 50, dial type release buttons 70a and 70b made of a rotating body provided with an operation portion on a circumferential surface concentric with the shaft portion are used instead of the release lever 50. Yes. Since the buttons other than the release buttons 70a and 70b are substantially the same as those in the first embodiment, common components are denoted by the same reference numerals, and description thereof is omitted.
[0077]
First, the release button 70a on the voltage electrode side will be described with reference to FIGS. The release button 70a is made of a synthetic resin molded product, and a part of the disk is cut out to form a substantially crescent shape in a side view, and an operation portion 72 having a circumferential surface exposed from the opening 1a of the vessel 1; The shaft portion 71 has a circumferential surface 71 a concentric with the circumferential surface of the operation portion 72, and projects from the surface of the operation portion 72 that faces the circumferential surface. The shaft portion 71 of the operation portion 72 projects. On the formed surface, a shaft portion 71 and a pushing portion 73 projecting side by side are integrally formed. Here, the operation piece 72 has a central piece of the terminal plate 21 in a state in which the circumferential surface 71a of the shaft portion 71 is in contact with an arcuate hook piece 21c extending from the central piece 21a of the terminal plate 21.

Thus, when the electric wire is disconnected from the terminal portion 20, the hook 72b of the operation portion 72 exposed from the opening 1a is pressed downward with the finger of the hand holding the body 1 in FIG. 39 (a). The release button 70b rotates counterclockwise in the drawing around the shaft portion 71 (see FIG. 39 (b)), and the pushing portion 73 pushes the receiving portion 23c of the locking piece 23 to bite into the electric wire. Since the protruding locking portion 23a is bent in a direction away from the contact piece 22 (electric wire), the electric wire can be pulled out from the electric wire insertion hole 15 with the other hand, and the drawing operation of the electric wire can be performed more easily than in the past. Thereafter, when the force to push the hooking portion 72b of the operation portion 72 is removed, the release button 70b is rotated to the initial position by the spring force of the locking piece 23.
[0080]
Thus, in the present embodiment, instead of the lever-shaped release means, the dial-type release button 70a made of a rotating body having the operation portion 72 provided on the circumferential surface concentric with the shaft portion 71 is used. As shown in 39, it is not necessary to form a large hole in the body 2 for accommodating the release means as in the above-described embodiments, and the rigidity of the body 2 can be increased.

By taking (the lever ratio) as large as possible, the lock portion 23a can be released with a smaller operating force using the principle of the lever.
[0081]
Next, the release button 70b on the ground electrode side will be described. The release button 70b is made of a synthetic resin molded product, and has an operation portion 72 formed in a substantially crescent shape when viewed from the side, and protrudes obliquely downward from the circumferential surface of the operation portion 72, and is provided in a recess 2g on the bottom surface of the vessel 1 The rod-shaped lever portion 72c exposed to the outside from the through-hole 2f and the circumferential surface 71a concentric with the circumferential surface of the operation portion 72 are provided so as to protrude from the surface facing the circumferential surface of the operation portion 72. The shaft portion 71 and a pushing portion 73 projecting side by side with the shaft portion 71 are integrally formed on the surface of the operation portion 72 on which the shaft portion 71 projects. Here, the operation portion 72 has a notch for allowing the center piece 21a and the contact piece 22 of the terminal plate 21 to escape in a state where the circumferential surface 71a of the shaft portion 71 is in contact with the hook piece 21c of the terminal plate 21. 72a is formed.
[0082]
The release button 70b is engaged with the terminal plate 21 by hooking the shaft portion 71 on the hook piece 21c in a state where the circumferential surface 71a of the shaft portion 71 is in contact with the arcuate hook piece 21c of the terminal plate 21. The pushing portion 73 of the release button 70b is disposed to face the receiving portion 23c of the locking piece 23. The lever portion 72c of the release button 70b protrudes outward from the through hole 2f in the bottom wall of the body 2.
[0083]
Thus, when the electric wire is removed from the terminal portion 20 ′, the lever portion 72c of the operation portion 72 exposed from the through hole 2f of the body 2 is moved with the finger of one hand holding the vessel 1 as shown in FIG. ), The release button 70b rotates around the shaft 71 counterclockwise in the figure (see FIG. 41 (b)), and the pushing part 73 pushes the receiving part 23c of the locking piece 23. By doing so, the locking part 23a biting into the electric wire is bent in a direction away from the contact piece 22 (electric wire), so that the electric wire can be pulled out from the electric wire insertion hole 15 with the other hand. Tripping work can be done easily. Thereafter, when the force to push the lever portion 72 c of the operation portion 72 is removed, the release button 70 b is rotated to the return position by the spring force of the locking piece 3.
