Description

【０００１】
【発明の属する技術分野】
本発明は、配線器具等の接続に用いられる電線接続端子装置及び電線接続端子装置を備えたコンセントやスイッチやコネクタや端子台やジョイントボックス等の配線器具に関するものである。
【０００２】
【従来の技術】
従来より、電線の接続作業を容易にするため、いわゆる速結端子構造のものを用いた電線接続端子装置が知られている。この速結端子構造のものを用いた電線接続端子装置は端子板と、電線の芯線を端子板に圧接接続するとともに電線の抜け止めを行う錠ばねと、錠ばねを撓ませることで電線の抜け止めを解除する解除釦とから成るものである。
【０００３】
【発明が解決しようとする課題】
上記の従来例においては、１つの端子部に複数の電線を接続する場合に、１枚の端子板に複数の錠ばねを並設し、コンセント装置本体に各錠ばねに対応させて複数の電線挿入口を設けている。そのため、電線挿入口から挿入された電線の芯線が、隣接する電線挿入口と対応する錠ばねの方へ挿入されてしまい、電線の接続がうまくいかずに接続作業に手間がかかるという問題があり、電線の芯線が撚線の場合には正確な接続作業が一層手間取るという問題があった。
【０００４】
本発明は上記問題点の解決を目的とするものであり、端子部に複数の電線を接続する際の接続作業を容易にすることができる電線接続端子装置及び電線接続端子装置を備えたコンセント及び電線接続端子装置を備えたスイッチ及び電線接続端子装置を備えたコネクタ及び電線接続端子装置を備えた端子台及び電線接続端子装置を備えたジョイントボックスを提供するにある。

【００２４】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて詳述する。本発明の電線接続端子装置は、本体１内に端子板２を収容するための収容部３を設け、この収容部３に端子板２を収容し、該端子板２に複数の錠ばね４を内装し、本体１に各錠ばね４に対応する電線挿入口５を設け、更に、本体１内には電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７が設けてあって、いわゆる速結端子構造となっている。そして、本発明は、上記速結端子構造の電線接続端子装置において、複数の錠ばね４を各別に収納するための複数のスペース１５を形成するために仕切り部８により仕切って、複数に仕切ったスペース１５内にそれぞれ錠ばね４を配置し、本体１に設けた複数の電線挿入口５が仕切り部８により仕切った各スペース１５にそれぞれ各別に連通するようになっている点に特徴がある。
【００２５】
図１乃至図１８には上記の構成の端子装置を備えた配線器具としてコンセントＡの例が示してある。
図１乃至図１８に示すコンセントＡは、英国工業規格（ＢＳ）に準拠する３ピンの接地コンセントＡに対応したコンセントＡについて例示するが、これに限定する趣旨ではなく、他の３ピンのコンセントＡや２ピンのコンセントＡに対応したコンセントＡについても、本発明の技術思想を適用することができることは言うまでもない。
【００２６】
このコンセントＡは、合成樹脂により略函形に形成されたボディ９と、ボディ９の前面に被着される板状の合成樹脂性のカバー１０とをねじ１１０で結合して本体１が構成してある。カバー１０には図２に示すように、３つの栓刃挿入口３５が開口させてあり、ボディ９の内部には、上記３つの栓刃挿入口３５にそれぞれ対向させて３つの刃受金具１４が配設してある。
【００２７】
さらに、ボディ９の内部には、３つの収容部３が設けてあり、ボディ９の背面にはそれぞれの収容部３と連通する電線挿入口５がそれぞれ３つずつ設けてある。また、３つの刃受金具１４と各別に電気的に接続された端子板２が各収容部３内に配設してある。
端子板２は図１乃至図８に示す実施形態では３個設けてあり、このうち２つの端子板２には略コ字状をした端子部１１から一体に連出した連出片１２に先端部に図１５のように鋲１３により刃受金具１４をかしめ固定して構成してある。残りの端子板２は端子部１１を設けてあるが、この端子部１１と刃受金具１４とは分離しており、端子部１１と刃受金具１４とはスイッチ機構を介して電気的に接離自在となっている。
【００２８】
各端子板２の端子部１１の内側は仕切り部８により３つのスペース１５に仕切ってあり、この実施形態では仕切り部８は板状の仕切り板よりなり、２枚の仕切り板が端子板２に電線６の芯線６ａの挿入方向と平行に端子板２と一体に折り曲げ形成してあって、２枚の仕切り板により端子板２内を３つのスペース１５に仕切ってある。
【００２９】
各端子板２の端子部１１内部を仕切り部８により仕切られて形成された３つのスペース１５はそれぞれ３つの電線挿入口５と各別に連通させてある。
上記各スペース１５には、弾性を有する金属製の板状部材で形成された錠ばね４がそれぞれ配設してある。この錠ばね４は、導電性の板状部材をまず略く字型に折り曲げ、折り曲げた一方の端をさらにＳ字型に折り曲げて形成してあり、く字型の先端片部４ａを電線挿入口５に対向させている。すなわち、上記の端子板２、２枚の仕切板よりなる仕切り部８、３つの電線挿入口５及び３つの錠ばね４により１つの速結端子構成部１７が構成してあり、各刃受金具１４ごとに計３個の速結端子構成部１７がボディ９に設けてある。
【００３０】
さらに、速結端子構成部１７に接続された電線を取り外すための電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７が設けてある。この解除釦７は１つの速結端子構成部１７に対して１個ずつ設けてある。この解除釦７はＴ字状をしており、図１４に示すように略三角形状に形成された幅広の解除部７ａと、該解除部７ａの前部の中央から前方に突出した幅狭のレバー部７ｂとで構成してある。幅広の解除部７ａは３つの錠ばね４に対向する幅を有している。解除釦７の解除部７ａとレバー部７ｂとは図９乃至図１１に示す図面で上に位置する上面に該当する面が弧状に連続している。幅狭のレバー部７ｂはボディ９に設けた挿入孔１８にスライド自在に挿入してあり、レバー部７ｂの両側に設けたガイド用フランジ６０が挿入孔１８の入口側の両端部に設けた逃がし溝６１にスライド自在にはめこんであり、また、レバー部７ｂを挿入孔１８に挿入して上記のようにガイド用フランジ６０を逃がし溝６１に嵌め込んだ状態でレバー部７ｂの弧状面７ｃが挿入孔１８の壁面に設けた弧状壁面１８ａに図９乃至図１１のように対応し、電線６の芯線６ａを挿入していない状態では錠ばね４のく字型の先端片部４ａのばね力により解除釦７が押されて図１０の実線のように弧状面７ｃが弧状壁面１８ａに押圧されている。ここで、仕切り部８を構成する仕切り板の一側縁は弧状面７ｃが当接する解除釦ガイド部１９となっている。また、幅広の解除部７ａは挿入孔１８よりも幅広なので、図１０の実線の状態で解除釦７が挿入孔１８から脱落することがなく、また、ガイド用フランジ６０が逃がし溝６１に挿入してあることで、解除釦７が挿入孔１８の所定の位置に位置決めされることになる。
【００３１】
今、電線６の芯線６ａを電線挿入口５から挿入すると、電線６は仕切り部８を構成する仕切り板により確実に対応する錠ばね４とコ字状の端子部１１の一片との間に挿入され、錠ばね４のく字型の先端片部４ａとＳ字型の先端片部４ｂとの各先端とにより芯線６ａが上記コ字状の端子部１１の一片に弾性的に押圧される。ここで、芯線６ａの接続を解除するには図１１（ａ）のようにドライバ２０をボディ９に設けた挿入孔１８の開口部の一内面とレバー部７ｂの前端との間から挿入し、図１１（ａ）→図１１（ｂ）のようにドライバ２０を差し込む。すると、解除釦７はドライバ２０により前方に押されるのであるが、この場合、弧状面７ｃが弧状壁面１８ａにガイドされながら前方に滑るように移動し、同時に解除部７ａの弧状面７ｃが仕切り部８を構成する仕切り板の一側縁に形成された解除釦ガイド部１９によりガイドされながら奥側に移動しながら錠ばね４のく字型の先端片部４ａを図１１（ｂ）のように押圧していき、このことによりく字型の先端片部４ａによる芯線６ａへの押圧が解除されるので、この状態で図１１（ｃ）のように電線６を引き抜くのである。この図１１（ｃ）の状態では、く字型の先端片部４ａのばね力により、弧状面７ｃの一部が解除釦ガイド部１９と弧状壁面１８ａに押し付けられた状態で図１１（ｃ）の矢印のようにレバー部７ｂによりドライバ２０を弾性的に押し付けてドライバ２０を保持することになって、電線６の引き抜き時にドライバ２０が脱落して先端片部４ａが芯線６ａに再び食い込まないようになっている。
【００３２】
図１６には解除釦７のレバー部７ｂに突起７ｄを設け、挿入孔１８の開口部の一内面に凹部１８ｄを設け、突起７ｄが凹部１８ｄに摺動自在に嵌め込んである例を示している。このように突起７ｄを設けておくと、ドライバ２０をボディ９に設けた挿入孔１８の開口部の一内面とレバー部７ｂの前端との間から挿入した場合、ドライバ２０により突起７ｄを押して突起７ｄの分だけ余分にドライバ２０により解除釦７を錠ばね４のく字型の先端片部４ａを押し付けて撓ませることができるものであり、また、ドライバ２０を差し込んだ状態での錠ばね４によるドライバ２０を押して保持する力も突起７ｄで余分に先端片部４ａを押した分だけ強く押圧支持されることになる。
【００３３】
ここで、本実施形態においては、幅広の解除部７ａは３つの錠ばね４に対向する幅を有しているので、上記電線６の引き抜きに当たって、単一の解除釦７をドライバ２０を挿入して奥側に移動させた際、１つの端子板２の内部を仕切り部８により仕切った３つのスペース１５に各別に内装した３つの錠ばね４を単一の解除釦７の幅広の解除部７ａにより同時に解除できるものである。また、本実施形態においては、１つの端子板２の内部を仕切り部８により３つの電線挿入口５に１対１に対応させて３つのスペース１５に仕切ってあるので、１つの電線挿入口５から挿入した電線６の芯線６ａが、隣接する電線挿入口５に対応したスペース１５に侵入するのを仕切り部８によって阻止することができる。
【００３４】
ところで、本実施形態においては、電線挿入口５の形状に特徴を有している。すなわち、図１２に示すように電線挿入口５は、その開口端付近の形状は略円形であり、内部に行くにしたがってその径が徐々に狭くなるテーパ面を備えた円錐状のガイド体２２を備え、ガイド体２２の先端部が略四角形に開口させてある。すなわち、この電線挿入口５は、その開口端付近は略円形であるが、内部において略四角形の四角孔５ａとなっている。
【００３５】
したがって、撚線からなる芯線を電線挿入口５に挿入していく過程において、上記電線挿入口５の略四角形の部分により、錠ばね４により押さえ込み易い形状に撚線をばらしてスムーズに撚線を差し込んで接続できるものであり、撚線と単線とで端子部１１の構造を変える必要がなく、いずれの芯線にも共用することができて汎用性が拡大するとともに取付作業も容易になるという利点がある。
【００３６】
また、本実施形態においては、前述のように、３つの端子部１１のうち１つの端子板２（実施形態では電圧極側の端子板２）について、その刃受金具１４と端子板２との間に、両者の電気的接続をオン・オフするスイッチ機構を設けてある。
このスイッチ機構は、図７に示すように端子板２より延設された端子片２ｂの端部に揺動自在に設けられて、一端に可動接点２４が固着された可動接触子２５と、上記端子板２に対応する刃受金具１４より延設された刃受端子片１４ａの端部に固着された固定接点２６と、可動接触子２５の表面を滑動する滑動子２７と、この滑動子２７が突出方向に弾性付勢されて進退自在に取着されたハンドル２８とから成り、ハンドル２８をカバー１０にシーソ動自在に取着してなる、いわゆるシーソスイッチである。
【００３７】
可動接触子２５は短冊形の金属部材により形成されており、その略中央部の両側辺に切欠部２５ａが対向させて設けてある。一方、端子板２より延設された端子片２ｂの先端両側辺にはリブ２ｃが突設してあり、このリブ２ｃを上記可動接触子２５の切欠部２５ａに嵌合してリブ２ｃにより可動接触子２５を揺動自在に保持している。すなわち、上記リブ２ｃと切欠部２５ａとを嵌合することによって、可動接触子２５の位置を固定することができる。
【００３８】
上記構成では、ハンドル２８をシーソ動させることによって、滑動子２７が可動接触子２５の表面を滑動しながら可動接触子２５を揺動させ、可動接点２４と固定接点２６とを接離させて刃受金具１４と端子板２との接続をオン・オフさせることができる。
また、可動接点２４と固定接点２６とが接触しているときに通電されて点灯し、上記スイッチ手段のオン・オフ状態を表示するパイロットランプ３０がボディ９の前面に配設してある。パイロットランプ３０の前面にはガラスあるいは透明樹脂からなるランプカバー３１が取着され、このランプカバー３１によってパイロットランプ３０が保護されている。そして、このパイロットランプ３０と対向する位置のカバー１０にはパイロットランプ３０の灯を前面に透過させる透孔１０ａが穿孔してあり、この透孔１０ａより上記ランプカバー３１の一部が外部に露出させてある。
【００３９】
よって、ハンドル２８を操作し、必要に応じて刃受金具１４と端子板２との電気的接続をオン・オフすることができるので、コンセントＡを使用しないときにオフにしておくことによって、感電事故の防止を図ることができるものである。また、刃受金具１４と端子板２との電気的接続をオンにしたときには、パイロットランプ３０が点灯してオン状態であることを容易に視認することができるという利点がある。
【００４０】
ところで、本実施形態においては、３つの栓刃挿入口３５のうちの２つを開閉自在に閉塞する扉部３７を備えた扉体３６をボディ９の前面に平行移動自在に取着してある。この扉体３６は、図１、図３に示すように、一端部が１つの栓刃挿入口３５の内部に進退自在に突出する主片３８と、主片３８の他端部両側面より一体に延設された一対の側片３９とにより全体が略Ｙ形に形成されている。すなわち、主片３８の栓刃挿入口３５の内部に突出する一端部が押動部４０であり、側片３９の先端部が扉部３７となる。
【００４１】
上記扉体３６は、コイルばね４１により主片３８の端部からなる押動部４０が栓刃挿入口３５内部に突出する方向に弾性付勢されている。さらに、栓刃挿入口３５より挿入される栓刃と当接する押動部４０の先端は斜めにカットされており、栓刃挿入口３５の内部に行くに従って押動部４０の突出量が多くなるようにしてある。
【００４２】
上記構成では、栓刃挿入口３５に栓刃を挿入していないときには、扉体３６がコイルばね４１により弾性付勢されているため、２つの栓刃挿入口３５が扉部３７によって閉塞され、万一の感電事故の防止を図ることができる。一方、栓刃を栓刃挿入口３５に挿入すれば、最初に押動部４０の先端に栓刃の先端が当接し、栓刃の挿入に伴い押動部４０がコイルばね４１の弾発力に抗して押動される。その結果、主片３８がボディ９の前面において平行移動し、側片３９も一体に移動するので、扉部３７によって閉塞されていた他の２つの栓刃挿入口３５が露出し、栓刃と刃受金具１４との接続が可能となる。逆に、栓刃を抜けばコイルばね４１の弾発力によって扉体３６は元の位置に復帰し、栓刃挿入口３５は閉塞される。
【００４３】
本実施形態のコンセントＡ装置は、例えば壁面などの造営面に配設されるもので、ボディ９の前面にねじにより取付けらたカバー１０によって造営面に取り付けられる。すなわち、カバー１０はボディ９よりも大きな外形寸法に形成してあって、カバー１０の外周部がボディ９の外周部よりも外側方に突出して取付け枠部４５を構成している。このようにカバー１０に取付け枠部４５を設けた本体１の取付けに当たっては、ボディ９を壁面に設けた取付孔に埋め込み、取付孔の周りの壁面にカバー１０の周縁部を当接して本体１が壁面に配設される。ここで、壁面の取付孔には予め取付用の埋込ボックス（図示せず）が埋設してあり、この埋込ボックスに取付ねじによってカバー１０を螺着するようにしている。したがって、カバー１０には上記取付ねじを挿通するための挿通孔１０ｂが設けてある。
【００４４】
しかしながら、上記のようにして本体１を壁面に配設した場合には、取付ねじがカバー１０の前面に露出し、見栄えが悪い。そこで、本実施形態においては、カバー１０の前面に取着される化粧プレート４６によってカバー１０の前面を覆い、コンセントＡの外観の見栄えを良くしている。
この化粧プレート４６は、合成樹脂により略四角形状に形成してあり、栓刃挿入口３５、ハンドル２８及びランプカバー３１を露出させるための孔が設けてあり、カバー１０に穿設された係止孔１０ｃに係止される係止片４６ａを背面より突設してある。すなわち、上記係止片４６ａをカバー１０の係止孔１０ｃに係止することにより、化粧プレート４６を容易にカバー１０に被着することができ、取付作業を簡単にすることができるという利点がある。
【００４５】
ところで、ボディ９の収容部３に端子板２を収納するに当たり、端子板２をボディ９に組み込む前に先に略Ｔ字状をした解除釦７をボディ９内に組み込み、その後、端子板２を組み込むものである。この場合、先に組み込んだ解除釦７はレバー部７ｂがボディ９の挿入孔１８に挿入されると共に弧状面７ｃがボディ９に設けた弧状壁面１８ａに当接した状態で納められる。この状態で、端子板２を収納するのであるが、この端子板２の挿入の際に、端子板２に設けた仕切り部８となる仕切り板の先端が解除釦７の幅広の解除部７ａの先端に当たって、端子板２の挿入ができなくなるおそれがある。このため、本発明においては、図１４に示すように解除釦７の幅広の解除部７ａの先端の仕切り板の先端が当たる部分に端子板２に一体に形成した仕切り板の挿入を容易にするための仕切り部逃がし用溝４８を設けてある。この仕切り部逃がし用溝４８を設けることで、ボディ９に先に解除釦７を組み込み、その後に端子板２を組み込む際に仕切り部８となる仕切り板を端子板２に設けたにもかかわらず解除釦７に引っ掛かることなくスムーズに端子板２を組み込むことができる。ここで、仕切り部８となる仕切り板の先端部はボディ９内に設けた係止溝４９に挿入係止されて位置決めされる。図１３には仕切り部８となる仕切り板の先端部はボディ９内に設けた係止溝４９に挿入係止されて位置決めされる状態が示してある。また、ボディ９の収容部３の開口縁部には図１０に示すように、収容部３の内面部を構成する内壁又はリブに端子板２組み込みガイド用のテーパ部５０が設けてあり、収容部３内に端子板２を組み込む際にこの端子板２組み込みガイド用のテーパ部５０の存在によりスムーズに端子板２を組み込むことができるものである。
【００４６】
ところで、本発明の端子装置において、仕切り部８を形成するに当たって、上記実施形態あるいは図５４のように端子板２の一部を折り曲げて仕切り部８を構成してもよいが、端子板２に別体の仕切り板を固着手段により固着して仕切り部８を形成してもよく、また、ボディ９乃至カバー１０の少なくとも一方（両方でもよい）に一体に仕切り部８となる突部を形成してもよい。端子板２の一部を折り曲げて仕切り部８を形成する際、仕切り部８の折り曲げ基部にスリット７０を設けて端子板２の一部を折り曲げて仕切り部８を形成しやすくするのが好ましい。また、図５５に示すように端子板２やボディ９のいずれとも別体の仕切り板よりなる仕切り部８をボディ９の係止溝４９に係止することでスペース１５を仕切るようにしてもよいものである。
また、図１７に示すように、ボディ１の収容部３の錠ばね４の先端片部４ａの先端部の幅方向の両側に対向するようにテーパ面部７２を有する撚線挿入ガイド用のリブ７１を設けておくのが好ましい。すなわち、図１８（ａ）はテーパ面部７２を有する撚線挿入ガイド用のリブ７１がない場合、図１８（ｂ）はテーパ面部７２を有する撚線挿入ガイド用のリブ７１を設けた場合をそれぞれ示している。しかしてテーパ面部７２を有する撚線挿入ガイド用のリブ７１がない場合、電線６の撚線よりなる芯線６ａはボディ１の収容部３の側面に押し付けられ、一番下に位置する撚線の素線は、錠ばね４の先端片部４ａをたわます力が上に位置する素線よりも必要である。このため、一番下の撚線の素線ほど座屈しやすくなる。これに対し、テーパ面部７２を有する撚線挿入ガイド用のリブ７１を設けると、撚線挿入ガイド用のリブ７１に設けたテーパ面部７２の効果で、撚線の素線が矢印の方向に移動し、錠ばね４の先端片部４ａの先端部に集まりやすくなり、挿入時に錠ばね４の先端片部４ａをたわます力が下に位置する素線も上に位置する素線のように小さくなって、下に位置する素線が座屈しくくなるものである。
【００４７】
上記した実施形態においては、カバー１０はボディ９よりも大きな外形寸法に形成してカバー１０の外周部にボディ９の外周部よりも外側方に突出した取付け枠部４５をカバー１０と一体に形成した例を示したが、取付け枠部４５を本体１を構成するボディ９及びカバー１０とは別体の部材により形成し、ボディ９又はカバー１０に別体の取付け枠部４５を取付けるようにしてもよい。
【００４８】
図１９乃至図３１にはボディ９又はカバー１０に別体の取付け枠部４５を取付ける一実施形態が示してある。
ボディ９又はカバー１０（実施形態においてはカバー１０）には外周部の両側壁にそれぞれ係止部１２０が設けてある。本実施形態においては、係止部１２０は上突部１２０ａと、下受け部１２０ｂとで構成してあり、上突部１２０ａと下受け部１２０ｂとは横方向に少しずれ且つ上下方向に隙間を介して突設してあり、更に上突部１２０ａの外側面は上に行くほどカバー１０の側壁からの突出長さが短くなるような傾斜面１２０ｈとなっている。このような上突部１２０ａと下受け部１２０ｂからなる係止部１２０はカバー１０の両側壁にそれぞれ複数設けてあるが、一方の側壁に設けた複数の係止部１２０と他方の側壁に設けた複数の係止部１２０とは位置を横方向にずらしてある。ここで、下受け部１２０ｂは一方の側壁側においては突起により構成してあり、他方の側壁部においては段状凹みにより構成してある。
【００４９】
カバー１０やボディ９とは別体の取付け枠部４５は図２７、図２８に示す実施形態においては合成樹脂により形成してあり、開口部の周囲の開口縁部のうち対向する開口縁部に複数の被係止部１２１が設けてあり、この被係止部１２１は上突部１２０ａが係止する係止溝部１２１ａと、下受け部１２０ｂが係止する係止突起１２１ｂとで構成してある。取付け枠部４５の上記被係止部１２１を設けた対向する開口縁部のうち一方の開口縁部の近傍に該開口縁部と平行にスリット１２４が設けてあり、このようにスリット１２４を設けることで、被係止部１２１を設けた一方の開口縁部分に弾性力を付与するような構成となっている。取付け枠部４５には壁面に埋設した埋込ボックスに取付けるための取付けねじを挿入するための挿通孔１０ｂが設けてあり、更に、４箇所に化粧プレート４６の背面側に設けた係止片４６ａを係止するための係止孔１０ａが設けてある。化粧プレート４６には図２７のように上記係止片４６ａ、コンセントＡの栓刃挿入口３５を露出する孔４６ｂ、ランプカバー３１が露出する孔４６ｃ、ハンドル２８を露出する孔４６ｄが設けてある。
【００５０】
しかして、ボディ９にカバー１０を組合せて構成した本体１に別体の取付け枠部４５を取付けるに当たっては、取付け枠４５の開口部に本体１をはめ込んで、取付け枠部４５の開口部の周囲の対向する開口縁部にそれぞれ設けた被係止部１２１と、本体１の両側壁にそれぞれ設けた（実施形態においてはカバー１０の両側壁にそれぞれ設けた）係止部１２０とを弾性的に係止することで取付けるものである。この場合、係止部１２０を構成する上突部１２０ａと係止溝部１２１ａとが係止し、下受け部１２０ｂと係止突起１２１ｂとが係止して、取付け枠４５が前後方向に外れないようになっている。ここで、上突部１２０ａに傾斜面１２０ｈを設けてあることで、該傾斜面１２０ｈをガイドとして上突部１２０ａを係止溝部１２１ａにはめ込むことができ、この際、スリット１２４を設けることで取付け枠部４５の一方の開口縁部に弾性が付与され、傾斜面１２０ｈのはめ込みに従って取付け枠部４５の一方の開口縁部が弾性変形しながらはめ込み作業が行われ、上突部１２０ａが係止溝部１２１ａに至った状態で取付け枠部４５の開口縁部の弾性復元力で係止溝部１２１ａと上突部１２０ａとが弾性的に係止することになる。なお、取付けに当たって、一方の係止部１２０と一方の被係止部１２１とを先に係止した状態で、この部分を支点として取付け枠部４５を回動して他方の係止部１２０と他方の被係止部１２１とを弾性的に係止するようにしてもよい。
【００５１】
このようにして図２４に示すように本体１に本体１の外周部から外側に突出するように取付け枠４５が取付けられるものである。取付け枠４５はすでに述べた実施形態と同様に化粧プレート４６を取付けて外観の見栄えを良くしている。化粧プレート４６は図２０乃至図２３のように取付けられるものである。すなわち、取付け枠部４５の係止孔１０ｃに化粧プレート４６の係止片４６ａが係止され、取付け枠部４５の全前面とカバー１０の前面の一部とが化粧プレート４６により覆われ、孔４６ｂ、４６ｃ、４６ｄからそれぞれ栓刃挿入口３５、ランプカバー３１、ハンドル２８が露出するものである。ここで、前述のように、一方の側壁に設けた複数の係止部１２０と他方の側壁に設けた複数の係止部１２０とを横方向に位置をずらし、これに対応して取付け枠部４５の対向する開口縁部に設けた被係止部１２１の位置もずらしているので、本体１と取付け枠部４５との取付け位置関係が一定になり、この結果、孔４６ｂ、４６ｃ、４６ｄと栓刃挿入口３５、ランプカバー３１、ハンドル２８との位置合わせが簡単になり、正確に取付けることができるものである。
【００５２】
ところで、取付け枠部４５と化粧プレート４６との合わせ面にはキーやドライバー等の化粧プレート外し用治具を挿入して化粧プレート４６を外すことを可能とするための化粧プレート外し用治具挿入部１２９が設けてある。図２７に示す実施形態においては該化粧プレート外し用治具挿入部１２９が取付け枠部４５に設けてあるが、化粧プレート４６の外周端部の背面側に化粧プレート外し用治具挿入部１２９を設けてもよい。また、図２７の実施形態においては、ボディ９やカバー１０とは別体の取付け枠部４５に化粧プレート外し用治具挿入部１２９を設けたが、図２に示す実施形態のように取付け枠部４５がカバー１０と一体物のものにおいても同様に化粧プレート外し用治具挿入部１２９を設けてもよい。このように取付け枠部４５と化粧プレート４６との合わせ面に化粧プレート外し用治具挿入部１２９を設けることで、化粧プレート４６を外す場合に、該化粧プレート外し用治具挿入部１２９にキーやドライバー等の化粧プレート外し用治具を挿入して簡単に化粧プレート４６を外すことができるものである。
【００５３】
次に他の実施形態を図１９、図２６、図３２乃至図３５に基づいて説明する。
本実施形態においては、本体１を構成する部材であるカバー１０又はボディ９の外周部の両側壁にそれぞれ係止部１２０を構成する孔１２０ｃを複数設けてあり、一方の側壁に設けた複数の孔１２０ｃの位置と他方の側壁に設けた複数の孔１２０ｃの位置とは横方向にずれて形成してある。本体１を構成する部材であるカバー１０又はボディ９とは別体の取付け枠部４５は金属により形成してあり、図３４に示すように開口部の対向する開口縁部にそれぞれ複数の突片１２１ｃよりなる被係止部１２１が設けてある。対向する開口縁部のうち一方の開口縁部には突片１２１ｃの開口部側とは反対側に沿って切り抜き孔１４０が設けてあり、このため、一方の開口縁部に設けた突片１２１ｃは両側が連結片１４１を介して取付け枠部４５に一体に連結された状態となっている。
【００５４】
しかして、本体１とは別体の取付け枠部４５を本体１に取付けるに当たっては、取付け枠部４５の開口部を本体１にはめ込み、本体１に対して取付け枠部４５を横方向に移動して切り抜き孔１４０を設けていない方の突片１２１ｃを一方の側壁の孔１２０ｃにはめ込んで係止し、この状態で、切り抜き孔１４０を設けた方の突片１２１ｃが図３５（ａ）のように他方の側壁の孔１２０ｃに対向するので、ドライバのような治具１４２を切り抜き孔１４０に挿入してドライバのような治具１４２を操作して突片１２１ｃの両側の連結片１４１部分を塑性変形させて突片１２１ｃを孔１２０ｃにはめ込んで係止することで取付けるものである。この場合、図３５（ａ）のようにまず切り抜き孔１４０の突片１２１ｃの背方側にドライバのような治具１４２を挿入して回転操作することで突片１２１ｃを孔１２０ｃにはめ込むことができるのであるが、ここで、図３５（ｂ）のように、突片１２１ｃを孔１２０ｃにはめ込んだ後に、更に、切り抜き孔１４０の連結片１４１の背方側に治具１４２を挿入して回転操作することでより深く突片１２１ｃを孔１２０ｃにはめ込むことができるものである。このようにして強度の強い金属製の取付け枠部４５を本体１に取付けることができる。
【００５５】
ところで、取付け枠部４５を導電性を有する金属により形成し、取付け枠部４５に導電性を有する係止片部１２２を設け、この導電性を有する係止片部１２２を接地極となる端子板２に設けた係止孔部１２３に圧入して端子板２及び取付け枠部４５を同電位とするようにしてもよいものである。
すなわち、図３４に示すように、取付け枠部４５の突片１２１ｃを設けた対向する両側縁部のうち切り抜き孔１４０を設けない方の側縁部から係止片部１２２を突設してある。一方、図１９に示すように、端子板２には係止孔部１２３が形成してあり、該端子板２の係止孔部１２３は図３２に示すようにカバー１０の側部の孔部１４３に対向している。そして、前述の実施形態と同様にして取付け枠部４５と本体１とを取付ける際、取付け枠部４５の開口部を本体１にはめ込み、本体１に対して取付け枠部４５を横方向に移動して切り抜き孔１４０を設けていない方の突片１２１ｃを一方の側壁の孔１２０ｃにはめ込んで係止する時に同時に孔部１４３から係止片部１２２を挿入して、該係止片部１２２を端子板２の係止孔部１２３に圧入し、その後、前述の実施形態と同様にして他方の突片１２１ｃ側を塑性変形させて他方の孔１２０ｃにはめ込んで係止するものである。このようにして端子板２及び取付け枠部４５を同電位にするものであり、取付け枠部４５は前述の実施形態と同様にして壁面に埋め込まれる埋め込みボックスに取付けられることでアースされることになる。
【００５６】
ここで、更に、図３２、図３４に示すように、化粧プレート４６を導電性を有する材料により形成し、該化粧プレート４６を導電性ねじ１３０により導電性を有する取付け枠部４５に取付けて化粧プレート４６を端子板２とを同電位として化粧プレート４６を介して壁にアースするようにしてもよい。図中１４９は化粧プレート４６に設けた導電性ねじ１３０の挿入孔であり、１５０は導電性ねじ１３０が螺合される取付け枠部４５に設けたねじ孔である。
【００５７】
ところで、図１９、図２６に示す実施形態においては本体１に、係止部１２０として上突部１２０ａ、下受け部１２０ｂ、孔１２０ｃを設けてあり、このように係止部１２０として上突部１２０ａ、下受け部１２０ｂ、孔１２０ｃを設けておき、更に、端子板２に係止孔部１２３を設けておくと、図２７に示すように被係止部１２１として係止溝部１２１ａと係止突起１２１ｂとを設けた合成樹脂製の取付け枠部４５の場合には係止部１２０として上突部１２０ａ、下受け部１２０ｂを用いて取付け枠部４５の弾性を利用して取付け、また、図３４に示すように被係止部１２１として突片１２１ｃを設けたもの金属製の取付け枠部４５の場合には係止部１２０として孔１２０ｃを利用して突片１２１ｃ部分の塑性変形を利用して取付けることができるものであって、共通の本体１に２種類の取付け枠部４５を選択的に取付けることができるものである。
【００５８】
もちろん図示を省略しているが、係止部１２０として上突部１２０ａ、下受け部１２０ｂのみを備えただけもの、あるいは係止部１２０として孔１２０ｃのみを備えただけのものであってもよいものである。
図３６乃至図３９には導電性を有する金属製の取付け枠部４５と接地極となる端子板２とを電気的に接続して同電位にするための他の実施形態が示してある。すなわち、本実施形態においては、接地極となる端子板２から突出片１５１を突設すると共に該突出片１５１にＭ字形をした突起１２７を設け、該Ｍ字形をした突起１２７を有する突出片１５１を本体１（実施形態においてはカバー１０）の側壁に設けた孔部１４３から外に突出させてある。一方、取付け枠部４５には図３８に示すように、孔１２６を有する突起片を設けてある。
【００５９】
そして、前述の実施形態と同様にして取付け枠部４５と本体１とを取付ける際、取付け枠部４５の開口部を本体１にはめ込み（この場合、取付け枠部４５を図３９（ａ）のＸ方向に移動して開口部を本体１にはめ込むことで、図３９（ａ）、（ｂ）のように取付け枠部４５に設けた孔１２６にＭ字形をした突起１２７がはめ込まれる）、次に、取付け枠部４５を横方向（つまり図３９（ａ）の矢印Ｙ方向）に移動することで、切り抜き孔１４０を設けていない方の突片１２１ｃを一方の側壁の孔１２０ｃにはめ込み、その後、前述の実施形態と同様にして他方の突片１２１ｃ側を塑性変形させて他方の孔１２０ｃにはめ込んで係止し、更に、孔１２６に挿入したＭ字形をした突起１２７を図３９（ｃ）のようにかしめて突起１２７と取付け枠部４５とを接続するものである。このようにして端子板２及び取付け枠部４５を同電位にするものであり、取付け枠部４５は前述の実施形態と同様にして壁面に埋め込まれる埋め込みボックスに取付けられることでアースされることになる。この実施形態においても、図３７、図３８に示すように、化粧プレート４６を導電性を有する材料により形成し、該化粧プレート４６を導電性ねじ１３０により導電性を有する取付け枠部４５に取付けて化粧プレート４６を端子板２とを同電位として化粧プレート４６を介して壁にアースするようにしてもよいものである。
【００６０】
次に、本発明の他の実施形態につき説明する。本実施形態においては、取付け枠部４５に本体１をはめ込んで取付けるための複数個の開口部を設け、取付け枠部４５に複数個の本体１を連設して取付けるものである。
図４０には取付け枠部４５に複数個の本体１を連設して取付ける場合の一実施形態が示してある。図４０には図２６に示す本体１を取付け枠部４５に複数個連設して取付けた例を示している。この実施形態においては、合成樹脂製の取付け枠部４５に複数個の取付け用の開口部が設けてあり、各開口部の対向する開口縁部にそれぞれすでに述べた実施形態と同様に被係止部１２１としての係止溝部１２１ａと係止突起１２１ｂとを設け、各開口部にそれぞれ本体１をはめ込んで、図１９乃至図３２に示す実施形態と同様の方法で各本体１をそれぞれ取付け枠部４５に設けた複数の開口部に取付けるものである。
【００６１】
また、図４１には図２６に示す本体１を取付け枠部４５に複数個連設して取付ける他例が示してあり、この実施形態においては、金属製の取付け枠部４５に複数個の取付け用の開口部が設けてあり、各開口部の対向する開口縁部にそれぞれすでに述べた実施形態と同様に被係止部１２１としての突片１２１ｃを設けると共に一方の開口縁部側において突片１２１ｃの近傍に切り抜き孔４０を設け、各開口部にそれぞれ本体１をはめ込んで、図３２乃至図３５に示す実施形態と同様の方法で各本体１をそれぞれ取付け枠部４５に設けた複数の開口部に取付けるものである。
【００６２】
次に、本発明の他の実施形態につき説明する。取付け枠部４５には既に述べたように、壁面に埋設した埋込ボックス１２８に取付け枠部４５を取付けるための取付けねじ１２５を挿入するための挿通孔１０ｂが形成してあるが、この挿通孔１０ｂは長円形となっている。このように挿通孔１０ｂを長円形とすることで、図４２に示すように埋め込みボックス１２８の施工時に傾いて取付けられても、取付け枠部４５を挿入孔１０ｂの長円方向に沿って回転させることで本体１を傾けることなく取付けることができるものである。
【００６３】
図４３には取付け枠部４５に複数の本体１を連設して取付けた場合における例であり、図４３に示すように埋め込みボックス１２８の施工時に傾いて取付けられても、取付け枠部４５を挿入孔１０ｂの長円方向に沿って回転させることで本体１を傾けることなく取付けることができるものである。
既に述べた実施形態においては、端子板２に鋲１３により刃受金具１４をかしめ固定したり、あるいは端子板２に接点を固着したりしているが、図４４（ａ）、（ｂ）、（ｃ）に示すように、端子板２に刃受金具１４を一体に形成したり、あるいは端子板２に固定接点２６を一体に形成したりしてもよい。また、固定接点２６に対応する刃受金具１４より延設された刃受端子片１４ａの端部にハンドル２８に設けた開閉素子１６０を回動自在に支持するための開閉素子受け部１６１を一体に形成してもよい（図４４（ｄ）参照）。
【００６４】
ここで、ハンドル２８の下部にはコイルスプリング１６２の上部がはめ込んであり、該コイルスプリング１６２の下部に開閉素子１６０が取付けてあり、開閉素子１６０に可動接点２４が設けてあり、ハンドル１６２を操作することで、コイルスプリング１６２が死点を越えると、反転して可動接点２４が固定接点２６に接触したり、あるいは離れたりするものである。
【００６５】
次に、ランプカバー３１をカバー１０に取付ける実施形態につき説明する。パイロットランプ３０を内装したランプカバー３１には弾性を有する係止脚片１３６が設けてあり、係止脚片１３６に係止爪部１３６ａが設けてある。本体の構成部材であるカバー１０にはランプカバーはめ込み孔１３５が形成してあり、このランプカバーはめ込み孔１３５に係止面部１３７が設けてある。しかして、パイロットランプ３０を内装したランプカバー３１を取付けるにはランプカバーはめ込み孔１３５にランプカバー３１をはめ込んで図２３に示すように係止脚片１３６の係止爪部１３６ａを係止面部１３７に弾性的に係止することで、ワンタッチで取付けるものである。
【００６６】
次に、図４５乃至図４８に基づいて本発明の他の実施形態につき説明する。本実施形態においては、図４８に示すように解除釦７のレバー部７ｂのドライバ挿入側の面と反対側の面（つまり弧状面７ｃを設けた方の面）の端部にドライバ誤挿入防止用の凸部１３２を設けてあり、また、ボディ９の挿入口１８の弧状壁面１８ａを設けた方の面の端部に凸部１３２を逃がすための凹部１３３を設けてある。ドライバ誤挿入防止用の凸部１３２は図４７に示すように正面視で略半円形状をしており、凹部１３３も正面視略半円形状をしており、ドライバ２０を挿入しない状態では図４５、図４７のようにドライバ誤挿入防止用の凸部１３２がボディ９の挿入口１８の入口の一面に位置しており、正面視略半円形状のドライバ誤挿入防止用の凸部１３２とこれを逃がすための正面視略半円形状の凹部１３３との間の隙間にドライバ２２を挿入しようとしても、該隙間が略半円形状の隙間であるため、マイナスドライバを挿入できず、したがって、誤って、レバー部７ｂの弧状面７ｃ側にドライバ２０を挿入して解除釦７を誤操作するのを防止するようになっている。このため、解除釦７をドライバ２０で操作するには必ず、解除釦７のレバー部７ｂのドライバ誤挿入防止用の凸部１３２と反対側の面とボディ９の挿入口１８の内面との間に図４６のようにして挿入する。そして、既に述べたようにドライバ２０を挿入して解除釦７を解除する動作が確実に行えることになる。ここで、ドライバ２０の操作で解除釦７は図４６の実線の状態から破線の状態に移動するが、この移動に伴い上記ドライバ誤挿入防止用の凸部１３２は凹部１３３内を奥に移動して解除釦７の移動の支障にならないようになっている。
【００６７】
上記した実施形態では本発明の電線接続端子装置を備えたコンセントＡの例を示したが、図４９には本発明の電線接続端子装置を備えたスイッチＢの例が示してある。この実施形態においては、ボディ９とカバー１０とで本体１を構成してあるが、この実施形態においては、ボディ９とカバー１０とを別体の組立て枠８０を用いて連結してある。すなわち、カバー１０に組立て枠８０を嵌め込んで取付け、この組立て枠８０に設けたＵ字状をした脚部８１を折り曲げてボディ９に設けた係止突起８２に係止することでボディ９をカバー１０に取付けるようになっており、このように本体１に取付けた組立て枠８０は壁面に取付けられる取付け枠に係止突片８２を利用して取付けられる。この実施形態においては、３個の端子板２のうち１つの端子板２に開閉接触子９０が回動自在に載置してあり、残りの２つの端子板２に接点部９１が設けてあり、開閉接触子９０は回動することで上記２つの接点部９１のいずれかに接触している。カバー１０に設けた枢支溝９２にはハンドル９３の支点用突起９３ａが回動自在に嵌め込んであり、ハンドル９３に設けた筒部９４内にコイルスプリング９５の上部を嵌め込み、コイルスプリング９５の下部が開閉接触子９０に嵌め込んである。したがって、ハンドル９３を支点用突起９３ａを中心に回動することで、コイルスプリング９５の作用により開閉接触子９０を反転回動させて上記接点を切り換えるものであり、ハンドル９３を逆に回動するとコイルスプリング９５が死点を越えることで反転回動し、上記と逆に開閉接触子９０を反転回動させて上記接点を切り換えるものである。この切り換えスイッチＢの機構は従来から公知の切り換えスイッチと同様である。但し、本発明においては、上記各端子板２にそれぞれ端子板２の端子部１１の内部を仕切り部８により仕切って複数のスペース１５を設けた点に特徴がある。仕切り部８を設けるに当たっては、この実施形態においては端子板２の一部を折り曲げて仕切り板を形成して仕切り部８を構成している例を示しているが、ボディ９乃至カバー１０の少なくとも一方又は両方に仕切り用のリブを設けて仕切り部８を構成してもよい。この端子板２の端子部１１内の仕切り部８により仕切られた複数のスペース１５内には前述のコンセントＡの実施形態と同様にそれぞれ各別に錠ばね４が内装され、また、この実施形態では図示を省略しているが、端子板２の端子部１１内部を仕切り部８により仕切られた複数のスペース１５はそれぞれ各別に電線挿入口と連通させてある。端子部１１、複数の電線挿入口及び複数の錠ばね４により１つの速結端子構成部１７が構成してある。速結端子構成部１７に接続された電線を取り外すための電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７が設けてある。この解除釦７の基本的な構造は前述のコンセントＡの実施形態の場合と同様であるので説明は省略する。この解除釦７の動作等は前述の図９乃至図１１に示す実施形態と同様であるので、この点の説明は省略する。また、電線挿入口の奥を四角形状にするということや、撚線挿入ガイド用のリブ７１に設けることや、解除釦７のレバー部７ｂ一面にドライバ誤挿入防止用の凸部１３２を設けるとと共にボディ９の挿入口１８に該凸部１３２を逃がすための凹部１３３を設けること等も同様に本実施形態にも適用できるものである。
【００６８】
図５０にはコネクタＣの例が示してある。この実施形態ではボディ９に設けた収容部に端子板２、錠ばね４、解除釦７を収容し、カバー１０をボディ９に取付けて本体１を構成してある。この実施形態においては端子板２の一部を折り曲げて仕切り板を形成して該仕切り板により仕切り部８を構成し、端子板２内を複数のスペース１５に仕切ってあって、各スペース１５にそれぞれ錠ばね４が収納してあり、この実施形態では図示を省略しているが、端子板２の端子部１１内部を仕切り部８により仕切られた複数のスペース１５はそれぞれ各別に電線挿入口と連通させてある。端子部１１、複数の電線挿入口及び複数の錠ばね４により１つの速結端子構成部１７が構成してある。速結端子構成部１７に接続された電線を取り外すための電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７の基本的な構造は前述のコンセントＡの実施形態の場合と同様であるので説明は省略する。また、この解除釦７の動作等は前述の図９乃至図１１に示す実施形態と同様であるので、この点の説明は省略する。また、電線挿入口の奥を四角形状にするということや、撚線挿入ガイド用のリブ７１に設けることや、解除釦７のレバー部７ｂ一面にドライバ誤挿入防止用の凸部１３２を設けるとと共にボディ９の挿入口１８に該凸部１３２を逃がすための凹部１３３を設けること等も同様に本実施形態にも適用できるものである。
【００６９】
図５１には端子台Ｄの例が示してある。この実施形態ではボディ９の収容部には解除釦７と、コ字状をした端子部１１を有する２個の端子板２と各端子部１１内に納めた錠ばね４とが収納してある。そして端子部１１の上横片から上方に向けて電線結線用突片１００を突設し、ボディ９にカバー１０を取付けて本体１を構成してある。この状態で上記電線結線用突片１００がカバー１０の孔１０１から突出し、この部分に電線を結線できるようになっている。この実施形態においてはボディ９の一部にボディ９と一体に仕切りリブを突設して、該仕切りリブを仕切り部８としてあって、端子板２同士を上記仕切り部８により仕切ってある。この場合、各端子板２に設けたコ字状をした端子部１１内の錠ばね４が納められるスペース１５が仕切り部８により仕切られることになる。この実施形態では図示を省略しているが、錠ばね４を納めた各スペース１５はそれぞれ各別に電線挿入口と連通させてある。複数の端子部１１、複数の電線挿入口及び複数の錠ばね４により１つの速結端子構成部１７が構成してある。速結端子構成部１７に接続された電線を取り外すための電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７の基本的な構造は前述のコンセントＡの実施形態の場合と同様であるので説明は省略する。また、この解除釦７の動作等は前述の図９乃至図１１に示す実施形態と同様であるので、この点の説明は省略する。また、電線挿入口の奥を四角形状にするということや、撚線挿入ガイド用のリブ７１に設けることや、解除釦７のレバー部７ｂ一面にドライバ誤挿入防止用の凸部１３２を設けるとと共にボディ９の挿入口１８に該凸部１３２を逃がすための凹部１３３を設けること等も同様に本実施形態にも適用できるものである。
【００７０】
図５２にはジョイントボックスＥの例が示してある。内部に錠ばね４が収納されるコ字状をした端子部１１を連結片１０３により連結して端子板２が形成してあり、複数の端子板２をボディ９に設けた収容部３に収容してある。ここで、互いに対となった端子板２同士は送り用リード板９７により電気的に接続してある。ボディ９には解除釦７がスライド自在に納装され、解除釦７のレバー部７ｂがボディ９の挿入孔にスライド自在に納装される。またボディ９にはカバー１０が取付けられて本体１が形成される。カバー１０には電線挿入口５が形成してある。ボディ９及びカバー１０の内部には仕切り部８を構成するための仕切り壁が形成してあって、該仕切り壁により隣合う端子板２の端子部１１同士が仕切ってあって、隣合う錠ばね４が収納されるスペース１５を仕切るようになっている。錠ばね４を納めた上記各スペース１５はそれぞれ各別に電線挿入口５と連通させてある。仕切り部８、複数の電線挿入口５及び複数の錠ばね４により１つの速結端子構成部１７が構成してある。速結端子構成部１７に接続された電線を取り外すための電線６の押圧を解除する方向に錠ばね４を押圧することができる解除釦７の基本的な構造は前述のコンセントＡの実施形態の場合と同様であるので説明は省略する。また、この解除釦７の動作等は前述の図９乃至図１１に示す実施形態と同様であるので、この点の説明は省略する。また、電線挿入口の奥を四角形状にするということや、撚線挿入ガイド用のリブ７１に設けることや、撚線挿入ガイド用のリブ７１に設けることや、解除釦７のレバー部７ｂ一面にドライバ誤挿入防止用の凸部１３２を設けるとと共にボディ９の挿入口１８に該凸部１３２を逃がすための凹部１３３を設けること等も同様に本実施形態にも適用できるものである。
【００７１】
なお、上記した各実施形態においては、仕切り部８により錠ばね４を各別に収納するスペース１５を仕切るに当たって、１つの仕切り部８により２つのスペース１５に仕切る例、２つの仕切りにより３つのスペース１５に仕切る例等を示しているが、必ずしもこれにのみ限定されず、４つ以上のスペース１５に仕切るものであってもよいのは勿論であり、この場合、１つの端子板２の内部を仕切り部８により複数のスペース１５に仕切る場合と、１つの端子板２の内部に１つに錠ばね４を納める１つのスペース１５を形成し、隣合う端子板２同士を仕切る仕切り部８により隣合う端子板２に設けたスペース１５同士を仕切るようにする場合とがあるのは上記各実施形態で述べた通りである。
