Description

本発明は、時間帯別電灯契約回路または一次送り回路を備えた分電盤に配置される時間帯別電灯契約回路用ブレーカまたは一次送り回路用ブレーカの端子と接続される端子台に関するものである。   The present invention relates to a terminal block connected to a terminal of a circuit breaker for hourly light contract circuit or a circuit breaker for primary feed circuit arranged on a distribution board equipped with a light contract circuit for each time zone or a primary feed circuit. .

住宅用分電盤は、商用電源を電灯やコンセント等へ分電するために設置される。住宅用分電盤には、主幹ブレーカや分岐ブレーカが配列され、商用電源と各ブレーカとを接続する端子台が搭載される。   Residential distribution boards are installed to distribute commercial power to electric lights and outlets. Residential distribution boards are equipped with trunk breakers and branch breakers, and are equipped with terminal blocks that connect commercial power sources to each breaker.

端子台には、商用電源と接続される一次側端子と、主幹ブレーカに接続される二次側端子とが設けられており、二次側端子に隣接するように時間帯別電灯契約回路用ブレーカまたは一次送り回路用ブレーカが接続される第二の二次側端子が設けられていた。この端子には、限定された数の時間帯別電灯契約回路用ブレーカまたは一次送り回路用ブレーカの接続が可能であった。
特開２００１−１５７３２２号公報 特開２００７−２０７４３４号公報 The terminal block is provided with a primary side terminal connected to the commercial power source and a secondary side terminal connected to the main circuit breaker. Alternatively, a second secondary terminal to which the primary feed circuit breaker is connected is provided. A limited number of breaker for electric light contract circuit or breaker for primary feed circuit could be connected to this terminal.
JP 2001-157322 A JP 2007-207434 A

しかしながら上記示した端子台では、二次側端子に接続できるブレーカの数が限定されてしまい、その接続されるブレーカの数に合わせた端子台を準備していたので、その都度、端子台を選択して取り付け作業をしなくてはならず、作業の効率が悪かった。また、端子台の取り付け構造も端子台の大きさにより異なってくるため、端子台に適応できる取り付け構造を住宅用分電盤に搭載しなくてはならなかった。   However, in the terminal block shown above, the number of breakers that can be connected to the secondary side terminal is limited, and a terminal block that matches the number of breakers to be connected was prepared. Therefore, the installation work had to be done, and the work efficiency was poor. Moreover, since the mounting structure of the terminal block varies depending on the size of the terminal block, a mounting structure that can be adapted to the terminal block must be mounted on the residential distribution board.

そこで本発明は、簡単な構造で、接続するブレーカの数を増やすことのできる端子台を提供することを目的とし、その構造は、時間帯別電灯契約回路用ブレーカまたは一次送り回路用ブレーカが接続される二次側端子部に、端子部延長用の接続バーを設け、接続バーは略Ｌ字状形状とし、端部を二次側端子部に回動可能にねじ止めすることを特徴とする。 Therefore, the present invention has an object to provide a terminal block that can increase the number of breakers to be connected with a simple structure, and the structure is connected to a breaker for an electric power contract circuit or a breaker for a primary feed circuit according to time of day. The secondary side terminal portion is provided with a connection bar for extending the terminal portion , the connection bar is substantially L-shaped, and the end portion is rotatably screwed to the secondary side terminal portion. .

以上述べたように、本発明に係る端子台は、時間帯別電灯契約回路用ブレーカまたは一次送り回路用ブレーカが接続される端子部に、端子部延長用の接続バーを設け、接続バーは略Ｌ字状形状とし、端部を二次側端子部に回動可能にねじ止めするため、同じ端子台で、接続するブレーカの数を増やすことができる。接続バーを使用する際には、接続バーを回転させることで、端子部を延長することができ、特別な加工は必要なく使用できる。 As described above, the terminal block according to the present invention is provided with the connection bar for extending the terminal part at the terminal part to which the breaker for the hourly electric power contract circuit or the breaker for the primary feed circuit is connected. Since it is L-shaped and the end portion is rotatably screwed to the secondary terminal portion, the number of breakers to be connected can be increased with the same terminal block. When the connection bar is used, the terminal portion can be extended by rotating the connection bar and can be used without any special processing.

本発明に係る端子台の実施例を図１〜図４の添付図面に基いて説明する。   An embodiment of a terminal block according to the present invention will be described with reference to the accompanying drawings of FIGS.

住宅用分電盤１に主幹ブレーカ２や分岐ブレーカ３等が配列されている。主幹ブレーカ２や分岐ブレーカ３の他に、電流制限器（図示せず）や一次送り回路用ブレーカや時間帯別電灯契約回路用ブレーカ４等が搭載される場合には、主幹ブレーカ２の一次側に端子台５が設けられる。端子台５は、支持台６に導体７を組み込んで構成されている。端子台５には商用電源からの電源線を接続する一次側端子８と、主幹ブレーカ２へ接続されるねじ式二次側端子９と、時間帯別電灯契約回路用ブレーカや一次送り回路用ブレーカ４とに接続されるプラグイン式二次側端子１０とを設けている。   A main circuit breaker 2 and a branch breaker 3 are arranged on the residential distribution board 1. In addition to the main breaker 2 and the branch breaker 3, when the current limiter (not shown), the breaker for the primary feed circuit, the breaker 4 for the electric light contract circuit according to time zone, etc. are mounted, the primary side of the main breaker 2 Is provided with a terminal block 5. The terminal block 5 is configured by incorporating a conductor 7 into a support base 6. The terminal block 5 includes a primary terminal 8 for connecting a power line from a commercial power source, a screw-type secondary terminal 9 connected to the main breaker 2, a breaker for an electric light contract circuit and a breaker for a primary feed circuit according to time of day. 4 is provided with a plug-in type secondary terminal 10 connected to the terminal 4.

プラグイン式二次側端子１０には、端子の板厚分下げた位置に延長体１１が設けられ、この延長体１１に接続バー１２が取り付けられる。接続バー１２は、住宅用分電盤１においてスペースに余裕のある方に向けて設けられ、端子台５のプラグイン式二次側端子１０が延長されることになる。   The plug-in type secondary terminal 10 is provided with an extension body 11 at a position lowered by the thickness of the terminal, and a connection bar 12 is attached to the extension body 11. The connection bar 12 is provided in the residential distribution board 1 so as to have a sufficient space, and the plug-in type secondary terminal 10 of the terminal block 5 is extended.

プラグイン式二次側端子１０にはプラグイン式端子を有する時間帯別電灯契約回路用ブレーカや一次送り回路用ブレーカ４が接続される。端子部の長さ分だけのブレーカ４しか接続することができないが、本発明では、プラグイン式二次側端子１０を延長可能である接続バー１２が設けられ、端子部に接続できるブレーカ４の数を増やすことができる。   The plug-in-type secondary terminal 10 is connected to a breaker for an hourly electric power contract circuit and a breaker 4 for a primary feed circuit having plug-in terminals. Although only the breaker 4 corresponding to the length of the terminal portion can be connected, in the present invention, a connection bar 12 that can extend the plug-in type secondary terminal 10 is provided, and the breaker 4 that can be connected to the terminal portion is provided. You can increase the number.

端子台５の構造は、プラグイン式二次側端子１０に設けられた延長体１１に取り付けられた接続バー１２を略Ｌ字状に形成し、端子部にはねじ止めにより回動可能に取り付けることを特徴とする。接続したいブレーカ４の数に対応させて、端子部の長さを変更できる構造である。少ない数のブレーカ４を接続する場合は、接続バー１２は端子台５に収納された状態である。さらにブレーカ４を増設する場合には、接続バー１２を端子台５から引き出して端子部を延長させて、その延長部分にもブレーカ４を接続して用いる。延長体１１が板厚分下げて端子部に設けられているので、接続バー１２を回動させ引き出したときには接続バー１２はプラグイン式二次側端子１０と同一面上に延長される。 Structure of terminal block 5 forms a connection bar 12 attached to the extension member 11 provided in the plug-in secondary terminal 10 in a substantially L shape, so as to be rotated by screwing the terminal portion It is characterized by being attached. The length of the terminal portion can be changed according to the number of breakers 4 to be connected. When connecting a small number of breakers 4, the connection bar 12 is housed in the terminal block 5. Further, when the breaker 4 is added, the connection bar 12 is pulled out from the terminal block 5 to extend the terminal portion, and the breaker 4 is connected to the extended portion. Since the extension body 11 is provided at the terminal portion with the plate thickness lowered, the connection bar 12 is extended on the same plane as the plug-in type secondary terminal 10 when the connection bar 12 is rotated and pulled out.

本発明に係る端子台では、従来のように回路数ごとに異なる端子台を準備する必要がなく、端子台にかかる金型費を抑え、安価に端子台を提供できる。   In the terminal block according to the present invention, it is not necessary to prepare a different terminal block for each number of circuits as in the prior art, and the mold cost for the terminal block can be suppressed, and the terminal block can be provided inexpensively.
