JP 2006-166645 A

分電盤３２に付加機能ユニット３１を組み込む場合には、付加機能ユニット３１専用に設けたスペースに取り付けるため、基台３３のサイズが大きくなり、製造コストが引き上げられると共に、分電盤３２の設置場所も制約されてしまうという欠点があった。 When the additional function unit 31 is incorporated in the distribution board 32, the base 33 is increased in size because it is installed in a space provided exclusively for the additional function unit 31, the manufacturing cost is increased, and the distribution board 32 is installed. There was a disadvantage that the place was also restricted.

そこで本発明は、基台上に付加機能ユニットを取り付ける専用のスペースを空けることなく、付加機能ユニットを取り付け可能とする付加機能ユニットの取り付け構造を提供することを目的とし、その構造は、付加機能ユニットの底面にはブレーカの内部に配置されている各極導電バーに対向する位置に溝部と共にブレーカの上面に付加機能ユニットの挿入口を設け、溝部には端子を設け、付加機能ユニットを挿入口に差し込むことで、端子と導電バーとを接続し導通可能としたことを特徴とする。 Therefore, the present invention has an object to provide an additional function unit mounting structure that allows an additional function unit to be mounted without leaving a dedicated space for mounting the additional function unit on the base. On the bottom of the unit, an insertion slot for the additional function unit is provided on the top surface of the breaker together with the groove at a position facing each pole conductive bar arranged inside the breaker. By connecting the terminal to the conductive bar, the terminal and the conductive bar are connected to be conductive.

また、ブレーカの内部に配置されている各極導電バーの上側には配線を渡さず、挿入口は各極導電バーの直上に設けることを特徴とする。 In addition, the wiring is not passed above the respective pole conductive bars arranged inside the breaker, and the insertion port is provided directly above each pole conductive bar.

また、ブレーカの内部には、各極導電バーの他に外部接点用導電バー・アース用導電バーを設けることができると共に、付加機能ユニットには、外部接点用導電バー・アース用導電バーに対向する接点を設けることを特徴とする。 In addition to each pole conductive bar, an external contact conductive bar and a ground conductive bar can be provided inside the breaker, and the additional function unit faces the external contact conductive bar and the ground conductive bar. A contact point is provided.

Since the terminal is provided in the groove and the additional function unit is inserted into the insertion port, the terminal and the conductive bar can be connected to be conductive, so there is no need to secure a dedicated space for the additional function unit on the distribution board. As a result, the distribution board can be made smaller, manufacturing costs can be reduced, and restrictions on the installation location of the distribution board can be reduced. Further, the additional function unit is a plug-in type, and it is easy to attach and remove. The additional function unit can exchange various functions such as a lightning protection function, a seismic function, an overcurrent alarm function, a safety light function, and a leakage alarm function, and these functions can be attached to the breaker itself.

本発明に係る付加機能ユニットの取り付け構造の実施例を図１〜図８の添付図面に基いて説明する。 An embodiment of the attachment structure of the additional function unit according to the present invention will be described with reference to the accompanying drawings of FIGS.

住宅用分電盤に取り付ける付加機能ユニット１の取り付け構造である。分電盤には、基台に主幹ブレーカや分岐ブレーカ等の電気機器を配列し、これらのブレーカ２間は導電バーで接続して構成される。このように構成された分電盤に、避雷機能、感震機能、過電流警報機能、保安灯機能、漏電警報機能等の機能を付加するために、これらの機能を持つ付加機能ユニット１を用いる。 It is the attachment structure of the additional function unit 1 attached to the distribution board for houses. In the distribution board, electric devices such as a main breaker and a branch breaker are arranged on a base, and these breakers 2 are connected by a conductive bar. In order to add functions such as a lightning protection function, a seismic function, an overcurrent alarm function, a safety light function, and a leakage alarm function to the distribution board configured in this way, the additional function unit 1 having these functions is used. .

付加機能ユニット１の底面部３にはブレーカ２内部に配列された導体４に対向する位置に溝部５を設ける。溝部５にはそれぞれＬ１相６ａ、Ｎ相６ｂ、Ｌ２相６ｃの電源用端子６を設けると共に、付加機能ユニット１の機能によって、アース用端子または外部接点用端子６ｄを設ける。電源用端子やアース用端子または外部接点用端子６はブレーカ２のケース内部に配列された導体４に接続し、ブレーカ２に種々の機能を付加する。 A groove portion 5 is provided on the bottom surface portion 3 of the additional function unit 1 at a position facing the conductors 4 arranged inside the breaker 2. The groove 5 is provided with a power terminal 6 for the L1 phase 6a, N phase 6b, and L2 phase 6c, respectively, and a ground terminal or an external contact terminal 6d depending on the function of the additional function unit 1. The power terminal, the ground terminal, or the external contact terminal 6 is connected to the conductor 4 arranged inside the case of the breaker 2, and various functions are added to the breaker 2.

付加機能ユニット１は、容易に取り付け取り外しのできるカートリッジ式とし、ブレーカ２の挿入口７に差し込める大きさのケースに、避雷機能、感震機能、過電流警報機能、保安灯機能、漏電警報機能等を成す部品を収納し、ブレーカ２の挿入口７に用途に合わせて選択した付加機能ユニット１を差し込む。設置後、他の機能を持たせる場合にも、取り付けてある付加機能ユニット１を外しまた別のユニット１を差し込み、簡単に機能の取替えが行える。また、挿入口７を複数設けることも可能であり、複数の付加機能ユニットを差し込み、ブレーカ２に機能を重ねて付加することができる。 The additional function unit 1 is a cartridge type that can be easily attached and removed, and in a case that can be inserted into the insertion slot 7 of the breaker 2, a lightning protection function, a seismic function, an overcurrent alarm function, a safety light function, and a leakage alarm function Etc. are accommodated, and the additional function unit 1 selected according to the application is inserted into the insertion port 7 of the breaker 2. Even when other functions are provided after installation, the attached additional function unit 1 can be removed and another unit 1 can be inserted to easily replace the functions. Also, a plurality of insertion ports 7 can be provided, and a plurality of additional function units can be inserted and functions can be added to the breaker 2 in an overlapping manner.

ブレーカ２にはケース表面に操作ハンドル８が設けられ、ケース内部にはＬ１相４ａ、Ｎ相４ｂ、Ｌ２相４ｃの電源極導体４が配列されている。これらの電源用導体４の上側には配線を渡さず、その直上に挿入口７を設ける。付加機能ユニット１を挿入口７に差し込むことで、付加機能ユニット１の端子がブレーカ２内部の導体に接続され、導通可能となりブレーカに種々の機能を付加することができる。種々の機能付加の必要がない場合には、分電盤に組み込み、ブレーカ２の端子部９に導電バーを接続し、通常用いるブレーカ２として使用する。 The breaker 2 is provided with an operation handle 8 on the case surface, and the L1 phase 4a, N phase 4b, and L2 phase 4c power supply electrode conductors 4 are arranged inside the case. The wiring 7 is not passed over the power supply conductors 4 and an insertion port 7 is provided immediately above them. By inserting the additional function unit 1 into the insertion port 7, the terminal of the additional function unit 1 is connected to the conductor inside the breaker 2 and becomes conductive, so that various functions can be added to the breaker. When it is not necessary to add various functions, the breaker 2 is incorporated into a distribution board, a conductive bar is connected to the terminal portion 9 of the breaker 2, and the breaker 2 is normally used.

図６〜図８に示すように、ブレーカ２内部には電源用導体の他にアース用導体や外部接点用導体４ｄを設ける。付加機能ユニット１側には、電源用端子の他にアース用端子または外部接点用端子６ｄを設けられているので、導体４と端子６を接続する。アース用導体はアースに接続されているので、避雷器ユニットを取り付けた場合、ブレーカから直接アースへと導電させる。また、外部接点用導体はブレーカの外部の接点に接続でき、例えば過電流警報ユニットを設けた場合、ブレーカから外部接点へ導電させ、警報音を発する。 As shown in FIGS. 6 to 8, the breaker 2 is provided with a grounding conductor and an external contact conductor 4d in addition to the power supply conductor. Since the additional function unit 1 is provided with a ground terminal or external contact terminal 6d in addition to the power supply terminal, the conductor 4 and the terminal 6 are connected. Since the earthing conductor is connected to earth, when the lightning arrester unit is installed, it conducts directly from the breaker to earth. The external contact conductor can be connected to an external contact of the breaker. For example, when an overcurrent alarm unit is provided, the breaker conducts from the external contact to generate an alarm sound.
