【発明の属する技術分野】
本発明は、扉の吊元端部内まで電線管を介して案内された電気錠側の電線と、前記電気錠に低電圧の電力を送る為にコンクリートに設けられた電線管を介し、建物の開口部に組み込まれた「たて枠内」まで配線された制御盤（操作盤）側の電線とを結線する通電用金具の結線方法に関する。
【０００２】
【従来の技術】
普通一般に電気錠は扉の開口端部内に設けられ、一方、該電気錠をコントロールする制御盤（操作盤）は、建物の出入り口等の壁面に設置されている。この場合扉側の電気錠と壁面側の制御盤は、扉の吊元端部及び該吊元端部と対向するたて枠にそれぞれ取付けられる「通電用金具」を介して電気的に接続される。
【０００３】
従来、この種の通電用金具の一例としては、実開昭６２−１２０６７０号公報に示されている。この公報記載の実施例は考案であるが、この考案から導き出せる通電用金具の結線方法を図に示すと、図１乃至図５の通りである。なお、説明の便宜上、図１乃至図５を従来の一実施例とする。
【０００４】
しかして、図１乃至図５に示す従来の通電用金具の結線方法に於いて、図１は全体の工程図であり、また図２乃至図５は各工程Ａ乃至Ｃの具体的な説明図である。
【０００５】
まずＡは、図２で示すように通電用金具１を扉２の吊元端部及び該吊元端部と対向するコンクリート側のたて枠３にそれぞれ取付ける為に、前記扉２の吊元端部の端面２ａ及びたて枠３の端面３ａをそれぞれ切欠する対向端面切欠工程である。この対向端面切欠工程Ａは、例えば扉２及びたて枠３を建物の出入り口に取付ける前に切欠図にしたがって行われる。その際予め後述する扉側ケース７と枠側ケース８の内壁面にそれぞれ上下段差状の取付けステーを切欠部５、６から突出するように溶着固定する。周知のように扉２は蝶番を介してたて枠３側に取付けられる。一方、たて枠３は建物の開口部を形成するコンクリート４の壁面に固定的に取付けられる。普通一般に扉２及びたて枠３は中空状態であり、この場合扉２の中は全体的に空っぽであるのに対し、たて枠３はその端面３ａからの奥行き空間は、２ｃｍ程度しかない。
【０００６】
この対向端面切欠工程Ａに於いては、前述したように、一般的に通電用金具１の取付け現場以外の場所（例えば製造工場）で予め行われるが、もちろん、現場でたて枠３及び扉２の取付け前後に行っても良い。切欠部５、６を形成する行為は、図示しない切欠手段を用い、扉２の吊元端部の端面２ａ及びこの端面２ａに対向するたて枠３の端面３ａに対して行われるが、各切欠部５、６の形成部位や大きさは、通電用金具１を構成する対向ケース７、８のそれぞれのフロント１０、１１の大きさを考慮して設定される。
【０００７】
また対向ケース７、８の大きさや形状は、扉２側並びにたて枠３側の内部空間や電気錠側の電線１２を案内する電線管１３並びにたて枠３内まで配線された制御盤側の電線１４を案内する電線管１５の位置を考慮する必要がある。
【０００８】
そこで、通電用金具１は、図２で示すように構成されている。すなわち、扉２側の切欠部５内に嵌め込まれ、かつ、奥行きが４乃至５ｃｍ程度の扉側ケース７と、一方、たて枠３側の切欠部６に嵌め込まれ、かつ、奥行きが２ｃｍ程度の枠側ケース８と、これらのケース７、８の全面開口部にそれぞれ垂直に固定され、かつ、前記切欠部５、６に左右・上下がぴったり嵌まり合う対向フロント１０、１１と、中間部がこれらのケース７、８に余裕を持ってＵ字型状に掛け渡され、かつ、一方の接続リード線端部１６は前記扉側ケース７の上壁７ａの貫通孔１７から突出すると共に、他方の接続リード線端部１８は前記枠側ケース８のテーパー状上壁８ａの貫通孔１９から突出する通電用電線本体２０とから構成されている。
【０００９】
次にＢは、通電用金具１の通電用電線本体２０の両方の接続リード線端部１６、１８を、それぞれ対応する電気錠側の電線１２と制御盤側の電線１４に結線する結線工程である。図３は特に枠側ケース８の接続リード線端部１８と制御盤側の電線１４との結線工程を示している。この場合制御盤側の電線１４はたて枠３の切欠部６から引き出した状態で接続リード線端部１８との結線が行われる。
【００１０】
ところで、一般に通電用電線本体２０は、被覆パイプ内にソレノイド用のリードを２本、施解錠用の信号を拾うためのリード線を３本、扉の開閉状態の信号を拾うためのリード線を２本有しているので、例えばこれら複数本のリード線を圧着端子を介して結線したり、或いは線端同士を固く寄り合わせた上からハンダ付けをすると、複数個の結線粒状部或いは圧着端子部２１が生じる。この点は、特に結線工程Ｂでは図示しないが、扉側ケース７の接続リード線端部１６の複数本のリード線と電気錠側の電線１２とを結線した場合も同様である。
【００１１】
次にＣは、通電用金具１の扉側ケース７と枠側ケース８を扉２の吊元端部内及びたて枠３内にそれぞれ嵌合固定する嵌合取付け工程である。図４は特に枠側ケース８をたて枠３内に嵌合固定する場合を示している。
【００１２】
なお、図２で示すように、扉２側とたて枠３側の各内壁面にそれぞれ上下段差状の取付けステー２５、２６が切欠部５、６に臨むように溶着固定されている。
【００１３】
しかして、扉側の取付けステー２５及びたて枠側の取付けステー２６の前記切欠部５、６に臨む挾持部２５ａ、２６ａには、それぞれメネジ２７が形成されているので、図４で示すように枠側ケース８をたて枠３内に嵌合固定する場合には、枠側ケース８のフロント１１の両端部にそれぞれ形成されたオネジ２８用嵌合孔２９を前記メネジ２７に符合させる。そして、枠側ケース８をたて枠３内に挿入し、そのフロント１１が切欠部６にぴったり一致した所で、前記固着手段としてのオネジ２８を介して枠側ケース８をたて枠３に固着する。
【００１４】
ところで、この嵌合取付け工程Ｃに於いては、図５で示すように枠側ケース８側の接続リード線端部１８と電線管１５側の電線１４との結線部分が、枠側ケース８のテーパ状上壁８ａと電線１４を案内する電線管１５との内部空間３０内に押し込まれた格好となる。
【００１５】
しかるに、上記構成に於いては、前記内部空間３０が非常に狭いので、電線１４、１８の収まりが悪いのみならず、電線本体を無理に内部空間３０に押し込むと、複数個の結線粒状部或いは圧着端子部２１が互いに干渉し合うと言う欠点があった。特に嵌合取付け工程Ｃに於いて、電線本体と共に枠側ケース８をたて枠３内に無理に押し込むと、時には結線部分が変に折れ曲がったり、或いは傷が付くという問題点があった。また電線の結線部分を点検、修理等をする場合には、フロントのみならず枠側ケースをたて枠の切欠部から取り外した上で行わなければならないので、手間や時間がかかると言う問題点があった。
【００１６】
【発明が解決しようとする課題】
本発明は以上のような従来の問題点に鑑み、第１の目的は電線を結線した際に生じた複数個の結線粒状部或いは圧着端子部が、電線本体の無理な押し込みより互いに干渉し合わないようにし、よって、結線部分が変に折れ曲がったり、或いは傷が付かないようにすることである。第２の目的は結線部分の点検、修理等を容易に行うことができることである。第３の目的は枠側ケースの上壁の形状を工夫し、たて枠内の狭い内部空間を少しでも有効的に活用することである。第４の目的は通電用金具の枠側ケースをたて枠に容易かつ確実に取付けることができることである。
【００１７】
【課題を解決するための手段】
本発明の通電用金具の結線方法は、扉の吊元端部内まで電線管を介して案内された電気錠側の電線と、前記電気錠に電力を送る為に電線管を介してたて枠内まで配線された制御盤側の電線とを結線する通電用金具の結線方法に於いて、前記たて枠は、建物の開口部に組み込まれ、かつ、上下段差状で切欠部を臨むように固定された取付けステーを有する中空状態であり、また、前記通電用金具１Ａは、扉側ケース７Ａと、枠側ケース８Ａと、これらのケース７Ａ、８Ａの全面開口部にそれぞれ垂直に固定された或いは固定される対向フロント１０Ａ、１１Ａとから構成されており、少なくとも通電用金具１Ａを扉２の吊元端部並びに該吊元端部に対向するたて枠３Ａにそれぞれ取付ける前に、扉２の吊元端部の端面２ａ及びたて枠３Ａの端面３ａにそれぞれ切欠部５、６Ａを形成する対向端面切欠工程Ａ１と、予め制御盤側の電線１４Ａを枠側ケース８Ａ内に導入した後に、該枠側ケース８Ａを該枠側ケースの上下端部にそれぞれ突出形成された垂直係合突片４１がたて枠３Ａ内の取付けステー２６Ａに係合するまで押し込んでたて枠３Ａの切欠部６Ａ内に嵌合する枠側ケース嵌合工程Ｂ１と、予め枠側ケース８Ａ内に支持片３６を介して収まっている通電用電線本体２０Ａの他方の接続リード線端部１８Ａと枠側ケース８Ａ内に導入された前記電線１４Ａとを枠側ケース８Ａ内で結線する結線工程Ｃ１と、最終工程に於いて、固着手段２８Ａを介してフロント１１Ａをたて枠３Ａの切欠部６Ａにぴったり嵌合するように前記取付けステー２６Ａに固定するフロント固定工程Ｄ１とを含むことを特徴とする。
【００１８】
上記構成に於いて、通電用金具１Ａを構成する枠側ケース８Ａの上壁８ｂが水平板状に形成されていることを特徴とする。またフロント固定工程Ｄ１では、固着手段２８Ａとしてのオネジ２８Ａをフロント１１Ａの嵌合孔２９Ａ及び枠側ケース８Ａの垂直係合突片４１の貫通孔４２に挿入し、かつ、取付けステー２６Ａのメネジ２７Ａに螺合させることにより、枠側ケース８Ａをたて枠３Ａ内に完全に固定することを特徴とする。
【００１９】
【発明の実施の形態】
以下、図面に示す本発明の実施の形態を通電用金具１Ａを用いて説明する。なお、本発明の実施例の説明に当たって前述した従来の一実施例と同一の構成部分には同一又は同様の符号を付し、重複する説明を省略する。また通電用金具１Ａを用いた場合に於ける扉側ケース７Ａの方の電線１２Ａの結線方法は、結線工程の後に扉側ケース７Ａの扉の吊元端部に対する嵌合取付け工程が行われる等、従来の実施例と同一なので、重複する説明を省略する。
【００２０】
まず図６は本発明の全体の工程図、図７は本発明の通電用金具１Ａ、図８乃至図１０は通電用金具１Ａを用いた場合に於ける枠側ケース８Ａの方の電線１４Ａの結線方法を示す各説明図、図１１は通電用金具１Ａの取付け状態を示す説明図である。
【００２１】
図６に於いて、Ａ１は対向端面切欠工程である。この対向端面切欠工程Ａ１は従来の実施例と特に異なる点はない。
【００２２】
次に枠側ケース８Ａの方の電線１４Ａの結線方法を説明する前に、通電用金具１Ａの具体的構成について説明する。
【００２３】
図７で示すように、通電用金具１Ａは、比較的奥行きがある扉側ケース７Ａと、奥行きが２ｃｍ程度の枠側ケース８Ａと、これらのケース７Ａ、８Ａの全面開口部にそれぞれ垂直に固定された、或いは固定される対向フロント１０Ａ、１１Ａと、中間部がこれらのケース７Ａ、８Ａに余裕を持ってＵ字型状に掛け渡され、かつ、一方の接続リード線端部１６Ａは前記扉側ケース７Ａの上壁７ａの貫通孔１７Ａからゴムブッシュ３５を介して突出すると共に、他方の接続リード線端部１８Ａは前記枠側ケース８Ａ内に固定的に設けられた支持片３６を介して水平板状の上壁８ｂから突出しないように該枠側ケース８Ａ内に収納されている通電用電線本体２０Ａとから構成されている。
【００２４】
なお、通電用電線本体２０Ａは、扉側ケース７Ａ内に固定された電線支持片３７を介して支持されている。また前記枠側ケース８Ａの上壁８ｂに形成された貫通孔１９Ａにはゴムブッシュ３８が設けられている。
【００２５】
しかして、この通電用金具１Ａが従来の通電用金具１と主に異なる点は、通電用電線本体２０Ａの他方の接続リード線端部１８Ａが枠側ケース８Ａ内に収まっていること、また枠側ケース８Ａの上壁８ｂが枠側ケース８Ａ内のスペースを極力広く活用するために水平板状に形成されていること、また結線行為の容易化を図るために、枠側ケース８Ａの開口上下縁部に上下段差状の取付けステー２６Ａとそれぞれ係合する垂直係合突片４１、４１を形成したこと、さらに、枠側ケース８Ａの垂直係合突片４１、４１と重なり合うようにたて枠３Ａの切欠部６Ａにぴったり嵌合するフロント１１Ａが枠側ケース８Ａと別体であることである。
【００２６】
なお、枠側ケース８Ａの前記垂直係合突片４１、４１には、メネジ２７Ａと符合する貫通孔４２が形成され、この貫通孔４２はフロント１１Ａの嵌合孔２９Ａとも一致する。
【００２７】
次にＢ１は、通電用金具１Ａの枠側ケース８Ａをたて枠３Ａの切欠部６Ａ内に嵌合する枠側ケース嵌合工程である。この枠側ケース嵌合工程Ｂ１では、枠側ケース８Ａをたて枠３Ａの切欠部６Ａ内に押し込む前に、予め制御盤側の電線１４Ａをゴムブッシュ３８を介して枠側ケース８Ａ内に導入し、しかる後に図８で示すように上下の垂直係合突片４１、４１がたて枠３Ａ内の取付けステー２６Ａにそれぞれ面接触状態になるまで枠側ケース８Ａ内に押し込む。本実施例では、この枠側ケース嵌合工程Ｂ１の段階ではまだ枠側ケース８Ａを取付けステー２６Ａに固定していないが、例えば取付けステー２６Ａ及び上下の垂直係合突片４１、４１に仮止め用ネジ孔を形成し、図示しない別個のネジにより枠側ケース８Ａを取付けステー２６Ａに仮固定しても良い。
【００２８】
次にＣ１は、枠側ケース８Ａ内に収まっている通電用電線本体２０Ａの他方の接続リード線端部１８Ａと枠側ケース８Ａ内に導入された制御盤側の電線１４Ａとを枠側ケース８Ａ内で結線する結線工程である。この結線工程Ｃ１に於ける結線行為は従来の実施例と同様であり、例えば圧着端子を利用して対応する信号用、作動用の各リード線を図９で示すようにそれぞれ接続する。したがって、この場合枠側ケース８Ａ内に複数個の結線粒状部或いは圧着端子部２１Ａが出来上がる。
【００２９】
次にＤ１は、固着手段の一例であるオネジ２８Ａを介し、フロント１１Ａをたて枠３Ａの切欠部６Ａにぴったり嵌合するようにたて枠３Ａ内の取付けステー２６Ａに固定するフロント固定工程である。このフロント固定工程ではオネジ２８Ａをフロント１１Ａの嵌合孔２９Ａ及び垂直係合突片４１の貫通孔４２に挿入し、かつ、取付けステー２６Ａのメネジ２７Ａに螺合させることにより、最終的には枠側ケース８Ａをたて枠３Ａ内に固定する。したがって、枠側ケース８Ａが取付けステー２６Ａに仮止めされている場合には、このフロント固定工程Ｄ１により、枠側ケース８Ａはフロント１１Ａにカバーされた状態でたて枠３Ａ内に完全に固定される。
【００３０】
【実施例】
以下、この欄では本発明の通電用金具の結線方法に使用される他の通電用金具１Ｂについて説明する。なお、この通電用金具１Ｂを説明するに当たって、本発明の通電用金具の結線方法に用いられた通電用金具１Ａと構成上同一の部分には同一又は同様の符号を付し、重複する説明を省略する。
【００３１】
しかして、図１２に示す通電用金具１Ｂの特徴は、やや大きめの２線変換アダプタ４０が通電用電線本体２０Ｂの扉側ケース７Ｂ内に位置する一方の接続リード線端部１６Ｂに設けられている点、またコネクタ４１が枠側ケース８Ｂ内に位置する前記通電用電線本体２０Ｂの端部に設けられている点、また予め枠側ケース８Ｂ内に支持片３６Ｂを介して収まっている通電用電線本体２０Ｂの他方（２本）の接続リード線端部１８Ｂと枠側ケース８Ｂ内に導入された制御盤側の電線１４Ｂとを、２個の圧着端子４２を介して該枠側ケース８Ｂ内で結線されている点である。なお、この通電用金具１Ｂの構成に於いては、２線変換アダプタ４０を枠側ケース８Ｂ内に配設しても良い。
【００３２】
したがって、このような通電用金具１Ｂを使用しても本発明の通電用金具の結線方法を利用することができる。
【００３３】
【発明の効果】
以上の説明から明らかなように、本発明にあっては次に列挙するような効果がある。
（１）電線を結線した際に生じた複数個の結線粒状部或いは圧着端子部を、そのまま枠側ケースに内蔵するので、従来のように電線本体の無理な押し込みにより結線部分が互いに干渉し合うようなこともない。よって、結線部分が変に折れ曲がったり、或いは傷が付かない。
（２）フロントを取り外すだけで、結線部分の点検、修理等を容易に行うことができる。
（３）枠側ケースの上壁の形状を工夫してあるので、たて枠内の狭い内部空間を少しでも有効的に活用することができる。したがって、枠側ケースに内蔵される結線部分の収まりが良く成る。
（４）請求項３記載の発明は、通電用金具の枠側ケースをたて枠に容易かつ確実に取付けることができる。
（５）請求項４記載の発明は、結線工程の容易化を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electric wire on the electric lock side guided through the electric conduit to the inside end of the door of the door, and an electric conduit provided on the concrete for sending low-voltage power to the electric lock. The present invention relates to a method of connecting a current-carrying metal fitting for connecting an electric wire on a control panel (operation panel) side wired up to “within a vertical frame” incorporated in an opening.
[0002]
[Prior art]
Generally, the electric lock is generally provided in the open end of the door, while the control panel (operation panel) for controlling the electric lock is installed on a wall surface such as a doorway of a building. In this case, the electric lock on the door side and the control panel on the wall surface side are electrically connected through a hanging end portion of the door and a “current-carrying metal fitting” attached to the vertical frame facing the hanging end portion. The
[0003]
Conventionally, an example of this type of energizing metal fitting is disclosed in Japanese Utility Model Publication No. 62-120670. The embodiment described in this publication is a device, and the connection method of the current-carrying metal fittings that can be derived from this device is shown in FIGS. 1 to 5. For convenience of explanation, FIGS. 1 to 5 are taken as a conventional example.
[0004]
Thus, in the conventional method of connecting the current-carrying metal fittings shown in FIGS. 1 to 5, FIG. 1 is an overall process diagram, and FIGS. 2 to 5 are specific explanatory diagrams of the processes A to C. It is.
[0005]
First, as shown in FIG. 2, A is used to attach the current-carrying metal fitting 1 to the hanging end portion of the door 2 and the concrete frame 3 facing the hanging end portion, respectively. This is an opposing end surface notch process in which the end surface 2a of the end portion and the end surface 3a of the vertical frame 3 are notched. This facing end face notch process A is performed according to a notch view before, for example, attaching the door 2 and the vertical frame 3 to the entrance of the building. At that time, upper and lower step-like mounting stays are welded and fixed to the inner wall surfaces of the door side case 7 and the frame side case 8 described later in advance so as to protrude from the notches 5 and 6, respectively. As is well known, the door 2 is attached to the vertical frame 3 via a hinge. On the other hand, the vertical frame 3 is fixedly attached to the wall surface of the concrete 4 forming the opening of the building. In general, the door 2 and the vertical frame 3 are in a hollow state. In this case, the interior of the door 2 is entirely empty, whereas the vertical frame 3 has a depth space of only about 2 cm from its end surface 3a. .
[0006]
In the facing end face notch process A, as described above, it is generally performed in advance at a place other than the installation site of the current-carrying metal fitting 1 (for example, a manufacturing factory). You may carry out before and after attachment of 2. The act of forming the notches 5 and 6 is performed on the end surface 2a of the hanging end portion of the door 2 and the end surface 3a of the vertical frame 3 facing the end surface 2a using not-shown notch means. The formation part and size of the notches 5 and 6 are set in consideration of the sizes of the fronts 10 and 11 of the opposing cases 7 and 8 constituting the metal fitting 1 for energization.
[0007]
The size and shape of the opposing cases 7 and 8 are such that the inner space on the door 2 side and the vertical frame 3 side, the conduit 13 for guiding the electric wire 12 on the electric lock side, and the control panel side wired up to the vertical frame 3. It is necessary to consider the position of the conduit 15 that guides the other wires 14.
[0008]
Therefore, the current-carrying metal fitting 1 is configured as shown in FIG. That is, it is fitted in the notch 5 on the door 2 side and has a depth of about 4 to 5 cm, and on the other hand, is fitted in the notch 6 on the vertical frame 3 side, and the depth is about 2 cm. Frame-side case 8, opposed fronts 10 and 11 that are fixed vertically to the entire openings of these cases 7 and 8, and that fit right and left and up and down in the notches 5 and 6, and an intermediate portion Is stretched around these cases 7 and 8 in a U-shape with a margin, and one connecting lead wire end 16 projects from the through hole 17 of the upper wall 7a of the door-side case 7, The other end portion 18 of the connecting lead wire is composed of a current-carrying electric wire body 20 protruding from the through hole 19 of the tapered upper wall 8a of the frame side case 8.
[0009]
Next, B is a wiring process for connecting both the connecting lead wire ends 16 and 18 of the energizing electric wire body 20 of the energizing bracket 1 to the corresponding electric lock side electric wire 12 and control panel side electric wire 14 respectively. is there. FIG. 3 particularly shows a connection process between the connection lead wire end 18 of the frame side case 8 and the electric wire 14 on the control panel side. In this case, the electric wire 14 on the control panel side is connected to the connecting lead wire end 18 in a state where the electric wire 14 is pulled out from the notch 6 of the vertical frame 3.
[0010]
By the way, in general, the current-carrying electric wire body 20 has two solenoid leads in the sheathed pipe, three lead wires for picking up signals for locking and unlocking, and lead wires for picking up signals for the door open / close state. Since it has two, for example, when these lead wires are connected via crimp terminals, or soldered after the ends of the wires are firmly brought together, a plurality of connected granular parts or crimp terminals Part 21 is produced. Although this is not shown in the connection process B in particular, the same applies to the case where a plurality of lead wires at the connection lead wire end portion 16 of the door side case 7 and the electric wire 12 on the electric lock side are connected.
[0011]
Next, C is a fitting attachment process in which the door-side case 7 and the frame-side case 8 of the metal fitting 1 are fitted and fixed in the hanging end portion of the door 2 and in the vertical frame 3, respectively. FIG. 4 particularly shows a case where the frame side case 8 is fitted and fixed in the frame 3.
[0012]
As shown in FIG. 2, upper and lower step-like mounting stays 25 and 26 are welded and fixed to the inner wall surfaces on the door 2 side and the vertical frame 3 side so as to face the notches 5 and 6, respectively.
[0013]
Then, female screws 27 are formed in the holding portions 25a and 26a facing the notches 5 and 6 of the door side mounting stay 25 and the vertical frame side mounting stay 26, respectively, as shown in FIG. When the frame side case 8 is vertically fitted and fixed in the frame 3, the male screw 28 fitting holes 29 respectively formed at both ends of the front 11 of the frame side case 8 are aligned with the female screw 27. Then, the frame side case 8 is inserted into the vertical frame 3 and the frame side case 8 is inserted into the vertical frame 3 via the male screw 28 as the fixing means when the front 11 exactly matches the notch 6. Stick.
[0014]
By the way, in this fitting and attaching step C, as shown in FIG. 5, the connection portion between the connection lead wire end 18 on the frame side case 8 side and the electric wire 14 on the conduit 15 side is connected to the frame side case 8. It becomes the shape pushed into the internal space 30 between the tapered upper wall 8a and the conduit 15 that guides the electric wire 14.
[0015]
However, in the above configuration, since the internal space 30 is very narrow, not only is the fit of the wires 14 and 18 bad, but when the wire body is forced into the internal space 30, a plurality of connected granular parts or There was a drawback that the crimp terminal portions 21 interfere with each other. In particular, in the fitting and attaching step C, if the frame side case 8 is forcibly pushed into the frame 3 together with the electric wire main body, there is a problem that the connecting portion is sometimes bent or damaged.

Each explanatory view showing a connection method, FIG. 11 is an explanatory view showing a mounting state of the energizing bracket 1A.
[0021]
In FIG. 6, A1 is a facing end face notch process. This facing end face notch process A1 is not particularly different from the conventional embodiment.
[0022]
Next, before explaining the method of connecting the wire 14A of the frame side case 8A, the specific configuration of the energizing bracket 1A will be described.
[0023]
As shown in FIG. 7, the current-carrying metal fitting 1A is fixed vertically to the door-side case 7A having a relatively deep depth, the frame-side case 8A having a depth of about 2 cm, and the openings of the entire surfaces of these cases 7A and 8A. Or fixed opposed front 10A, 11A and an intermediate portion are spanned around these cases 7A, 8A in a U-shape with a margin, and one connecting lead wire end 16A is connected to the door. The side case 7A protrudes from the through hole 17A of the upper wall 7a through the rubber bush 35, and the other connecting lead wire end 18A is fixed to the frame side case 8A via a support piece 36 fixedly provided. The electric wire main body 20A for energization is accommodated in the frame side case 8A so as not to protrude from the horizontal plate-shaped upper wall 8b.

Next, B1 is a frame-side case fitting step for fitting the frame-side case 8A of the energizing bracket 1A into the notch 6A of the vertical frame 3A. In this frame side case fitting step B1, before the frame side case 8A is pushed into the notch 6A of the frame 3A, the electric wire 14A on the control panel side is introduced into the frame side case 8A via the rubber bush 38 in advance. Thereafter, as shown in FIG. 8, the upper and lower vertical engagement protrusions 41, 41 are pushed into the frame side case 8A until they come into surface contact with the mounting stay 26A in the vertical frame 3A. In the present embodiment, the frame side case 8A is not yet fixed to the mounting stay 26A at the stage of the frame side case fitting step B1, but it is temporarily fixed to the mounting stay 26A and the upper and lower vertical engagement protrusions 41, 41, for example. A screw hole may be formed, and the frame side case 8A may be temporarily fixed to the mounting stay 26A with a separate screw (not shown).
[0028]
Next, C1 connects the other connecting lead wire end 18A of the energizing electric wire body 20A housed in the frame side case 8A and the control panel side electric wire 14A introduced into the frame side case 8A to the frame side case 8A. It is a wiring process which connects within. The connecting action in this connecting step C1 is the same as that in the conventional example. For example, the corresponding signal and actuating lead wires are respectively connected using crimp terminals as shown in FIG. Therefore, in this case, a plurality of connected granular portions or crimp terminal portions 21A are completed in the frame side case 8A.
[0029]
Next, D1 is a front fixing process in which the front 11A is fixed to the mounting stay 26A in the vertical frame 3A so that the front 11A is fitted to the notch 6A of the vertical frame 3A through the male screw 28A which is an example of fixing means. is there. In this front fixing step, the male screw 28A is inserted into the fitting hole 29A of the front 11A and the through hole 42 of the vertical engaging protrusion 41, and is screwed into the female screw 27A of the mounting stay 26A. The side case 8A is fixed in the vertical frame 3A. Therefore, when the frame side case 8A is temporarily fixed to the mounting stay 26A, the frame side case 8A is completely fixed in the vertical frame 3A while being covered by the front 11A by the front fixing step D1.
