Description

本発明は、主として建築物の屋内配線に使用されている平形被覆電線、通常ＶＶＦケーブル又は単にＦケーブルと呼ばれている電線（以下Ｆケーブルという）を使用した屋内配線時の電線どうしの接続や、分岐線の取り出し、必要に応じて行われる片切スイッチ用電線や３路スイッチ用電線の取り出し箇所において使用するための端子台に関するものである。 The present invention mainly relates to the connection of wires during indoor wiring using a flat coated electric wire, which is mainly used for indoor wiring of buildings, or an electric wire (hereinafter referred to as F cable), usually called a VVF cable or simply an F cable. The present invention relates to a terminal block for use at a place where a branch line is taken out and a wire for a one-way switch or a three-way switch is taken out as necessary.

現在では、建築物等の屋内配線に際して使用される電線は、Ｆケーブルがその大半を占めるに至っている。その電線どうしの接続や分岐線の取り出しには、特許文献１にみられるような、被覆を剥離した複数の裸電線を絶縁被覆を施した銅スリーブ内に挿通し、先端を閉塞した被覆の外部から加圧して銅スリーブを圧着変形させることによって電線どうしを接続する手段が広く知られている。 At present, F cables are the majority of electric wires used for indoor wiring of buildings and the like. For connecting the wires and taking out the branch line, as shown in Patent Document 1, a plurality of bare wires with the coating peeled are inserted into a copper sleeve with insulation coating, and the outside of the coating with the tip closed Means for connecting electric wires by pressurizing and deforming a copper sleeve by pressure are widely known.

また、このような電線どうしを集めて接続するという通電手段に代えて、特許文献２にみられるように、被覆を剥離した裸電線を、抜け止め用スプリングを嵌め込んだ良導体の通電金具の長手方向の両側から差し込んで、電線どうしを接続するようにした電線接続用コネクタも知られていて広く使用されている。
特開平１１−２２４７００号公報特開平９−５５２３９号公報 Further, in place of the energizing means for collecting and connecting the electric wires, as shown in Patent Document 2, the length of the conductive metal fitting with a good conductor fitted with a retaining spring is used to remove the bare electric wire from which the coating has been peeled off. Wire connection connectors that are inserted from both sides of the direction to connect the wires are also known and widely used.

しかしながら、従来から知られ実行されているこの種の電線接続手段にあっては、何れの手段のものも、単純に電線どうしを接続するものであって、必要数の分岐線を任意に取り出すことはできないものであった。また、片切スイッチ回路用線や３路スイッチ回路用線を、これらの金具から直接取り出すこともできないという課題を有するものであった。 However, with this type of wire connecting means known and practiced in the past, any means simply connects the wires, and the necessary number of branch lines can be taken out arbitrarily. It was something that could not be done. In addition, there is a problem that it is not possible to directly take out a single-cut switch circuit line or a three-way switch circuit line from these fittings.

殊に、従来のこの種の電線接続手段にあっては、一旦所要の配線が終わった後に、追加的に分岐回路用の線や片切スイッチ回路用や３路スイッチ回路用の線を増設することは、実質的に多大な手数と時間を必要とするものであった。 In particular, in the conventional wire connecting means of this type, after the required wiring is finished, additional lines for branch circuits, one-side switch circuits, and three-way switch circuits are additionally added. That required a substantial amount of work and time.

そこで、本発明は、このような従来の電線接続手段が有していたこれらの課題を解決することを目的とし、初期の配線時には必要な自由な数の分岐線や、片切スイッチ回路用線や、３路スイッチ回路用線を直接取り出すことができ、一旦当初の所要の配線が終わった後に生じた追加的な分岐回路線の増設や、片切スイッチ回路用線や３路スイッチ回路用線の増設を、極めて容易に短時間でできるようにした平形被覆電線用端子台を提供しようとするものである。 Therefore, the present invention aims to solve these problems that the conventional electric wire connecting means has, and a free number of branch lines required for initial wiring, and a line for one-side switch circuit. Also, the three-way switch circuit line can be directly taken out, and additional branch circuit lines created after the initial required wiring is once completed, the one-way switch circuit line, and the three-way switch circuit line Therefore, it is intended to provide a terminal block for a flat coated electric wire which can be expanded easily in a short time.

以上の説明から既に明らかなように、本発明にいうところの平形被覆電線用端子台は、建築物の任意の箇所に固定できるようにした第１エンド部材と第２エンド部材との間に介在させるコネクタブロック体を、これらのエンド部材と連結可能で、ブロック体どうしも相互に連結可能なものとし、これらの連結を相互に差込むという極めて簡易な操作によって、ブロック体どうしの連結とブロック体相互の電気的接続とを同時に行うことができるようにし、必要な任意の数だけ順次的に差込むという操作だけで、屋内配線時に必要な電線どうしの接続や、必要な数の分岐線の取り出しを容易に行うことができるという顕著な効果を期待することが出来るに至ったのである。 As is apparent from the above description, the flat coated electric wire terminal block according to the present invention is interposed between the first end member and the second end member which can be fixed to any place of the building. The connector block body to be connected can be connected to these end members, the block bodies can be connected to each other, and the connection between the block bodies and the block body can be performed by an extremely simple operation of inserting these connections into each other. It is possible to make electrical connections to each other at the same time, and it is possible to connect the wires necessary for indoor wiring and to take out the required number of branch lines by simply inserting the required number in sequence. It was possible to expect a remarkable effect that it can be easily performed.

また、本発明は、前記のように、第１エンド部材と第２エンド部材との間に、必要な数と、必要な種類のコネクタブロックを差し込む操作によって、同時に電気的接続をも完了することが出来るようにしたものであるから、当初の屋内配線のみならず、後に必要性が生じた増設線を得ることも極めて容易に短時間でできるという効果をも期待することが出来るに至ったのである。 Further, as described above, according to the present invention, the electrical connection can be completed at the same time by inserting a necessary number and a necessary type of connector block between the first end member and the second end member. Because it was possible to obtain not only the original indoor wiring, but also the effect that it is possible to obtain an extension line that has become necessary later in a very short time. is there.

このエンド部材間に介在させるブロック体として、片切スイッチ回路を組込んだブロック体や、３路スイッチ回路を組込んだブロック体を形成し、これらのブロック体をエンド部材や分岐回路線等のブロック体との差し込み操作によって、ブロック体どうしの連結とブロック体相互の電気的接続とを同時に行うことができるようにしたので、片切スイッチ回路や、３路スイッチ回路を極めて容易に得ることができ、広範囲の配線に用いることができるという顕著な効果も期待することが出来るに至ったのである。 As a block body interposed between the end members, a block body incorporating a one-sided switch circuit or a block body incorporating a three-way switch circuit is formed, and these block bodies are used as end members, branch circuit lines, etc. By connecting the block bodies and electrically connecting the block bodies at the same time by the insertion operation with the block bodies, it is possible to obtain a single-cut switch circuit and a three-way switch circuit very easily. It is possible to expect a remarkable effect that it can be used for a wide range of wirings.

本発明は、上記の構成としたものであるから、その実施に当たっては、本発明にいうところの電線接続用又は電線分岐用のブロック体の場合には、電源線及び接続線又は分岐線を挿入する通電金具５を、各ブロック体の結合と同時に結合ブロック体間の電気的接続ができるものとし、片切スイッチ用のブロック体は、片切スイッチ線用のハウジングと片切負荷線用のハウジングとの組み合わせによって片切スイッチ回路を組込んだブロック体とし、３路スイッチ用のブロック体は、一方の３路スイッチ線用ハウジングと、他方の３路スイッチ線用ハウジングと、３路負荷線用ハウジングとの組み合わせによって３路スイッチ用回路を組込んだブロック体としておくことができる。 Since the present invention has the above-described configuration, in the case of the implementation, in the case of the block body for electric wire connection or electric wire branching according to the present invention, a power supply line and a connection line or branch line are inserted. The energizing metal fitting 5 to be connected can be electrically connected to each other at the same time as the respective block bodies are coupled. And a block body for a three-way switch, one for the three-way switch line housing, the other for the three-way switch line housing, and for the three-way load line A block body in which a circuit for a three-way switch is incorporated can be provided in combination with the housing.

このようにしておくことによって、必要な任意数の接続線や分岐線やの取り出し、片切スイッチ用線や３路スイッチ用線の取り出しを行うことができる。また、配線工事後の増設工事に当たっても、これら所要のブロック体を所要個数増結することによって、所要の増設線を取り出すことができるので、好都合なばかりではなく、屋内配線作業や屋内線の増設作業の能率を大幅に向上させることができる。 By doing in this way, it is possible to take out an arbitrary number of necessary connection lines and branch lines, and to take out one-off switch lines and three-way switch lines. Also, even if the expansion work after the wiring work is done, the required extension lines can be taken out by adding the required number of these block bodies, so it is not only convenient, but also the indoor wiring work and the indoor line extension work The efficiency of can be greatly improved.
