Description

本発明は住宅用分電盤に関し、特に速結端子から成る二次側端子を有し、この二次側端子が分電盤正面を向かず、電線の接続がし難い分岐ブレーカが組み付けられて成る住宅用分電盤に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board for residential use, and in particular, a branch breaker having a secondary side terminal composed of a quick-connecting terminal, the secondary side terminal not facing the front of the distribution board, and having difficulty in connecting electric wires is assembled. It relates to a distribution board for residential use.

近年、分岐ブレーカの小型化、薄型化が進んでおり、従来左右に配置していた速結端子から成る二次側端子を縦に配置することで、幅方向の薄型化を図ったものが普及している。
特許文献１は、このような薄型の分岐ブレーカを組み付けた住宅用分電盤の一例を示し、組み付けられている分岐ブレーカは、一次側端子と二次側端子とがブレーカハウジングの前面と背面に対向するように配置されている。そのため、特許文献１に開示されているように、分電盤に組み付けた際に一次側端子が上方に向けて配置されると、二次側端子は下方に向けて配置された。 In recent years, branch breakers have become smaller and thinner, and by vertically arranging the secondary terminals, which consist of quick-connect terminals that were conventionally arranged on the left and right, thinning in the width direction has become popular. is doing.
Patent Literature 1 shows an example of a distribution board for residential use in which such a thin branch breaker is assembled. arranged to face each other. Therefore, as disclosed in Patent Literature 1, when the primary side terminals were arranged facing upward when assembled to the distribution board, the secondary side terminals were arranged facing downward.

特開２０１５－１３９２５０号公報JP 2015-139250 A

上記特許文献１に開示されているように、一次側端子、二次側端子の双方をブレーカハウジングに縦配置することで分岐ブレーカを薄くでき、分電盤内に省スペースで多数の分岐ブレーカの組み付けが可能となった。
しなしながら、分電盤に組み付けられた分岐ブレーカは、薄型化した弊害として分岐配線する電線を接続する二次側端子が下方（或いは上方）等分電盤前方から見て側方を向き、且つ端子が前後方向に重なるように配置されているため、二次側端子が見辛く特に奥側の端子への結線がし辛かった。 As disclosed in Patent Document 1, by arranging both the primary side terminal and the secondary side terminal vertically in the breaker housing, the branch breaker can be thinned, and a large number of branch breakers can be installed in the distribution board while saving space. It was possible to assemble.
However, the branch breaker installed in the distribution board faces sideways when viewed from the front of the distribution board, such that the secondary side terminals that connect the electric wires for branch wiring face downward (or upward) as a side effect of the thinning. In addition, since the terminals are arranged so as to overlap in the front-rear direction, it is difficult to see the secondary side terminals, and it is particularly difficult to connect to the terminals on the far side.

そこで、本発明はこのような問題点に鑑み、二次側端子が縦配置された薄型ブレーカが組み付けられた住宅用分電盤であっても、個々の分岐ブレーカへの分岐配線の結線作業が容易な住宅用分電盤を提供することを目的としている。 Therefore, the present invention has been made in view of such problems, and even in a residential distribution board in which thin breakers with vertically arranged secondary terminals are assembled, it is not necessary to connect branch wires to individual branch breakers. The object is to provide a simple residential distribution board.

上記課題を解決する為に、請求項１の発明は、主幹ブレーカと複数の分岐ブレーカとが収容される住宅用分電盤であって、分岐ブレーカが組み付けられる基台に、負荷に至る分岐配線を接続するための分岐配線接続端子と、分岐ブレーカの二次側端子と電線を介して接続されて、分岐配線接続端子に基台内で接続されて成る中継端子とを設け、分岐配線を分岐配線接続端子に接続すると、分岐配線が分岐ブレーカの二次側端子に電気的に接続されると共に、中継端子及び分岐配線接続端子のうち少なくとも中継端子は、組み付けられる分岐ブレーカの二次側端子が位置する部位の近傍に配置され、且つ中継端子及び分岐配線接続端子は電線を挿入して接続を完了する速結端子で形成されて成り、更に分岐配線接続端子には検電孔が設けられ、分岐配線接続端子の通電状態を容易に確認できることを特徴とする。
この構成によれば、負荷へ至る分岐配線を分岐配線接続端子に接続すれば、分岐ブレーカの二次側端子に接続される。そのため、分岐ブレーカの二次側端子が電線を接続し難い配置であっても、分岐配線接続端子を基台上の視認し易い場所に配置すれば、この分岐配線接続端子を使用して分岐配線を容易に分岐ブレーカに接続できる。 In order to solve the above-mentioned problems, the invention of claim 1 is a distribution board for residential use in which a main breaker and a plurality of branch breakers are accommodated, and a base on which the branch breakers are assembled is provided with a branch wiring leading to a load. and a relay terminal connected to the secondary side terminal of the branch breaker via an electric wire and connected to the branch wiring connection terminal in the base, branching the branch wiring When connected to the wiring connection terminal, the branch wiring is electrically connected to the secondary side terminal of the branch breaker , and at least the relay terminal of the relay terminal and the branch wiring connection terminal is connected to the secondary side terminal of the branch breaker to be assembled.

Therefore, even if the secondary side terminal of the branch breaker is arranged so that it is difficult to connect the electric wire, if the branch wiring connection terminal is arranged on the base at a place where it is easy to see, the branch wiring connection terminal can be used to connect the branch wiring. can be easily connected to the branch breaker.

更に、中継端子は分岐ブレーカの二次側端子近傍に配置されるため、二次側端子と接続操作し易いし、中継端子及び分岐配線接続端子が速結端子で形成されることで、容易に接続操作できる。 Furthermore, since the relay terminal is arranged near the secondary side terminal of the branch breaker, it is easy to connect with the secondary side terminal. You can operate the connection.

加えて、分岐ブレーカの検電孔を使用すること無く、また分岐配線を抜き取ることなく導通検査を実施でき、利便性が良い。 In addition, the continuity test can be performed without using the voltage detection hole of the branch breaker and without extracting the branch wiring, which is convenient.

請求項２の発明は、請求項１に記載の構成において、基台の分岐配線接続端子の近傍には、分電盤ハウジングの背部から分岐配線を引き込んで分岐配線接続端子に接続するための電線挿通口が形成されていることを特徴とする。
この構成によれば、分岐配線接続端子の近傍に電線挿通口が設けられているため、分電盤の背部から導入した分岐配線を、分電盤ハウジング内で引き回すことなく分岐配線接続端子に接続でき、別途引き回し空間を設ける必要がない。
According to the invention of claim 2 , in the structure of claim 1 , an electric wire for drawing the branch wiring from the back of the distribution board housing and connecting it to the branch wiring connection terminal is provided in the vicinity of the branch wiring connection terminal of the base. It is characterized in that an insertion hole is formed.

It is possible, and there is no need to provide a separate routing space.

本発明によれば、負荷へ至る分岐配線を分岐配線接続端子に接続すれば、分岐ブレーカの二次側端子に接続される。そのため、分岐ブレーカの二次側端子が電線を接続し難い配置であっても、分岐配線接続端子を基台上の視認し易い場所に配置すれば、この分岐配線接続端子を使用して分岐配線を容易に分岐ブレーカに接続できる。 According to the present invention, when the branch wiring leading to the load is connected to the branch wiring connection terminal, it is connected to the secondary side terminal of the branch breaker. Therefore, even if the secondary side terminal of the branch breaker is arranged so that it is difficult to connect the electric wire, if the branch wiring connection terminal is arranged on the base at a place where it is easy to see, the branch wiring connection terminal can be used to connect the branch wiring. can be easily connected to the branch breaker.

The base 1 constitutes the back of the distribution board housing and is formed as a member attached to the wall surface. The cover plate (not shown) and the base 1 constitute a distribution board housing.

基台１には、主幹ブレーカ取付部１１、分岐ブレーカ取付部１２、後方から電線を導入する電線挿通口１３、更に後述する中継端子５、分岐配線接続端子６が設けられ、決められた部位に主幹ブレーカ２、複数の分岐ブレーカ３が組み付けられる。
そして、蓋板により機器が組み付けられた基台１の前面のうち少なくとも機器の操作部を除く部位が閉塞されて分電盤は構成される。 The base 1 is provided with a main breaker mounting portion 11, a branch breaker mounting portion 12, a wire insertion port 13 for introducing a wire from the rear, a relay terminal 5 and a branch wiring connection terminal 6, which will be described later. A main breaker 2 and a plurality of branch breakers 3 are assembled.
Then, the distribution board is configured by closing at least a part of the front surface of the base 1 to which the equipment is assembled with a cover plate, excluding at least the operation part of the equipment.

この基台１に組み付けられる分岐ブレーカ３は、ブレーカハウジング上部に電路をオン／オフ操作する操作ハンドル３１、背部に電源側端子である一次側端子３２、前面に負荷側端子である二次側端子３３が配置されている。一次側端子３２は銅バーを把持して接続される差込式端子、二次側端子３３は電線を挿入するだけで接続される速結端子で構成され、何れの端子も縦に配置された薄型ブレーカである。基台１には、操作ハンドル３１を前方に向けて組み付けられる。 The branch breaker 3 assembled to the base 1 has an operation handle 31 for turning on/off the electric circuit on the top of the breaker housing, a primary terminal 32 as a power source terminal on the back, and a secondary terminal as a load terminal on the front. 33 are arranged. The primary side terminal 32 is a plug-in type terminal that is connected by gripping a copper bar, and the secondary side terminal 33 is a quick-connecting terminal that is connected by simply inserting an electric wire. Both terminals are arranged vertically. It is a thin breaker. The base 1 is assembled with the operating handle 31 facing forward.

また、主幹ブレーカ２及び分岐ブレーカ３は単相３線式電路に対応し、２つの電圧極Ｌ（Ｌ１，Ｌ２）と中性極Ｎから成る３端子を有している。そして、分岐配線８は２本の電線から成り、１００ボルト負荷に至る電路を形成する場合は、分岐ブレーカ３の一方の電圧極Ｌと中性極Ｎに接続され、２００Ｖ負荷に対応する電路を形成する場合は、２つの電圧極Ｌ１，Ｌ２の端子に接続される。尚、分岐配線８は、接地線を具備する場合は３線で構成される。 The main breaker 2 and the branch breaker 3 correspond to a single-phase three-wire electric circuit, and have three terminals consisting of two voltage poles L (L1, L2) and a neutral pole N. The branch wiring 8 consists of two electric wires, and when forming an electric circuit up to a 100V load, it is connected to one voltage pole L and neutral pole N of the branch breaker 3 to form an electric circuit corresponding to a 200V load. If formed, it is connected to the terminals of the two voltage poles L1 and L2. Incidentally, the branch wiring 8 is composed of three wires when the ground wire is provided.

主幹ブレーカ２は、下部に一次側端子２１、上部に二次側端子２２を配置して基台１に組み付けられる。また、基台１の分岐ブレーカ取付部１２の上部には、分岐ブレーカ３の一次側端子３２を接続するために、前後に重なるように且つ左右方向に帯状に形成された３枚の銅バー４が配設されている。
主幹ブレーカ２の二次側端子２２は、この銅バー４の一端から棒状に延設された接続バー４ａが接続される。 The main breaker 2 is assembled to the base 1 with the primary side terminal 21 arranged in the lower part and the secondary side terminal 22 arranged in the upper part. In addition, three copper bars 4 formed in a belt shape in the left-right direction so as to overlap in the front-rear direction are provided on the upper portion of the branch breaker mounting portion 12 of the base 1 in order to connect the primary side terminal 32 of the branch breaker 3 . are arranged.
A secondary side terminal 22 of the main breaker 2 is connected to a connecting bar 4a extending from one end of the copper bar 4 in a bar shape.

一方、分岐ブレーカ３は、差込式端子で形成された一次側端子３２を上方に向け、速結端子で形成された二次側端子３３を下方に向けて取り付けられ、基台１に組み付けた状態で一次側端子３２は銅バー４に接続される。 On the other hand, the branch breaker 3 is attached to the base 1 with the primary side terminal 32 formed of a plug-in terminal directed upward and the secondary side terminal 33 formed of a quick connection terminal directed downward. The primary side terminal 32 is connected to the copper bar 4 in this state.

電線挿通口１３は、組み付けられた分岐ブレーカ３の二次側端子３３が配置される位置の近くとなる分岐ブレーカ取付部１２の下方に形成されている。そして、この電線挿通口１３と分岐ブレーカ取付部１２の間に、中継端子５及び分岐配線接続端子６の一部が形成されている。特に、中継端子５は組み付けられた分岐ブレーカ３の二次側端子３３が配置される位置の近傍に配置されている。
尚、分岐配線接続端子６は、この中継端子５に隣接する電線挿通口１３の上部と、電線挿通口１３の下部とに分けて形成されている。 The wire insertion opening 13 is formed below the branch breaker mounting portion 12 near the position where the secondary side terminal 33 of the assembled branch breaker 3 is arranged. A portion of the relay terminal 5 and the branch wiring connection terminal 6 is formed between the wire insertion opening 13 and the branch breaker mounting portion 12 . In particular, the relay terminal 5 is arranged near the position where the secondary side terminal 33 of the assembled branch breaker 3 is arranged.
The branch wiring connection terminal 6 is divided into an upper portion of the wire insertion opening 13 adjacent to the relay terminal 5 and a lower portion of the wire insertion opening 13 .

中継端子５、分岐配線接続端子６は、分岐ブレーカ取付部１２の分岐ブレーカ３組み付け可能数と同数設形成され、何れも一対の速結端子５ａ，６ａにより形成されている。
中継端子５は、分岐ブレーカ３の列に平行するよう１列に形成され、対応する分岐ブレーカ３の二次側端子３３に合わせて配置されている。そして、分岐ブレーカ３の二次側端子３３の使用する２端子と一対の速結端子５ａとが電線７を介して接続されて使用される。 The relay terminals 5 and the branch wiring connection terminals 6 are formed in the same number as the branch breaker 3 can be attached to the branch breaker mounting portion 12, and each is formed of a pair of quick connection terminals 5a and 6a.
The relay terminals 5 are formed in a line parallel to the line of the branch breakers 3 and are arranged in alignment with the secondary terminals 33 of the corresponding branch breakers 3 . The two terminals used by the secondary side terminal 33 of the branch breaker 3 and the pair of quick-connection terminals 5a are connected via the electric wire 7 and used.

また分岐配線接続端子６は、中継端子５と対を成して形成され、対を成す中継端子５と分岐配線接続端子６とは基台１の内部で接続されている。
図４はＡ部拡大説明図であり、中継端子５と分岐配線接続端子６とが基台１内で導体９により接続されている様子を示している。このように、対を成す中継端子５と分岐配線接続端子６とが接続されており、中継端子５と分岐ブレーカ３の二次側端子３３とを電線７で接続すれば、分岐配線接続端子６を分岐ブレーカ３の二次側端子３３としての使用が可能となる。
結果、分岐配線８を分岐配線接続端子６に接続すれば、分岐ブレーカ３への接続が完了し、分岐ブレーカ３の二次側端子３３に分岐配線８を直接接続する必要がなくなる。 The branch wiring connection terminal 6 is paired with the relay terminal 5 , and the paired relay terminal 5 and the branch wiring connection terminal 6 are connected inside the base 1 .
FIG. 4 is an enlarged explanatory view of part A, showing how the relay terminal 5 and the branch wiring connection terminal 6 are connected by the conductor 9 within the base 1. As shown in FIG. In this way, the paired relay terminal 5 and the branch wiring connection terminal 6 are connected. can be used as the secondary side terminal 33 of the branch breaker 3.
As a result, when the branch wiring 8 is connected to the branch wiring connection terminal 6 , the connection to the branch breaker 3 is completed, and the branch wiring 8 does not need to be directly connected to the secondary side terminal 33 of the branch breaker 3 .

ここで、分岐配線接続端子６の構成を具体的に説明する。分岐配線接続端子６は、一対の速結端子６ａで形成されるが、図１に示すように２つの群（第１の群Ｇ１、第２の群Ｇ２）に分けて形成されている。
第１の群Ｇ１は、中継端子５の列に隣接する電線挿通口１３の上部に配置され、第２の群Ｇ２は電線挿通口１３の下部に配置されている。
また、各分岐配線接続端子６は、速結端子６ａ毎にその近傍に検電孔６ｂを備えている。検電孔６ｂは、基台１の内部で速結端子６ａに電気的に接続されており、テスター等のプローブを挿入して通電状態を確認できるよう構成されている。 Here, the configuration of the branch wiring connection terminal 6 will be specifically described. The branch wiring connection terminals 6 are formed of a pair of quick-connection terminals 6a, which are divided into two groups (a first group G1 and a second group G2) as shown in FIG.
The first group G1 is arranged above the wire insertion opening 13 adjacent to the row of the relay terminals 5, and the second group G2 is arranged below the wire insertion opening 13. As shown in FIG.
Each branch wiring connection terminal 6 has a voltage detection hole 6b in the vicinity of each quick connection terminal 6a. The voltage detection hole 6b is electrically connected to the quick connection terminal 6a inside the base 1, and is configured so that a probe such as a tester can be inserted to check the energized state.

第１の群Ｇ１は、列設された複数の中継端子５のうち、奇数番目の中継端子５と基台１内で接続されている。即ち、奇数番目の分岐ブレーカ３が配置された構成となっている。一方、第２の群Ｇ２は、偶数番目の中継端子５と基台１内で接続されている。即ち、偶数番目の分岐ブレーカ３が配置された構成となっている。このように配置することで、例えば、第１の群Ｇ１を一方の電圧極Ｌ１と中性極Ｎとを接続する群とし、第２の群Ｇ２を他方の電圧極Ｌ２と中性極Ｎとを接続する群にでき、２つの電圧極Ｌ１，Ｌ２のバランスのとれた配電が可能となる。 The first group G1 is connected within the base 1 to the odd-numbered relay terminals 5 among the plurality of relay terminals 5 arranged in line. That is, the configuration is such that odd-numbered branch breakers 3 are arranged. On the other hand, the second group G2 is connected to even-numbered relay terminals 5 within the base 1 . That is, the configuration is such that even-numbered branch breakers 3 are arranged. By arranging in this way, for example, the first group G1 is a group connecting one voltage pole L1 and the neutral pole N, and the second group G2 is a group connecting the other voltage pole L2 and the neutral pole N. can be connected in groups, allowing a balanced distribution of the two voltage poles L1, L2.

このように、負荷へ至る分岐配線８を分岐配線接続端子６に接続すれば、分岐ブレーカ３の二次側端子３３に接続される。そのため、分岐ブレーカ３の二次側端子３３が電線を接続し難い配置であっても、分岐配線接続端子６を基台１上の視認し易い場所に配置すれば、この分岐配線接続端子６を使用して分岐配線８を容易に分岐ブレーカ３に接続できる。
また、中継端子５は分岐ブレーカ３の二次側端子３３の近傍に配置されるため、二次側端子３３と接続操作し易いし、中継端子５及び分岐配線接続端子６が速結端子で形成されることで、容易に接続操作できる。
更に、分岐配線接続端子６には検電孔６ｂが設けられているため、分岐ブレーカ３の検電孔を使用すること無く、また分岐配線８を抜き取ることなく導通検査を実施でき利便性が良い。
また、分岐配線接続端子６の近傍に電線挿通口１３が設けられているため、分電盤の背部から導入した分岐配線８を、分電盤ハウジング内で引き回すことなく分岐配線接続端子６に接続でき、別途引き回し空間を設ける必要がない。 If the branch wiring 8 leading to the load is connected to the branch wiring connection terminal 6 in this way, it is connected to the secondary side terminal 33 of the branch breaker 3 . Therefore, even if the secondary side terminal 33 of the branch breaker 3 is arranged so that it is difficult to connect an electric wire, the branch wiring connection terminal 6 can be easily connected by arranging the branch wiring connection terminal 6 on the base 1 at an easily visible location. The branch wiring 8 can be easily connected to the branch breaker 3 by using.
In addition, since the relay terminal 5 is arranged near the secondary side terminal 33 of the branch breaker 3, it is easy to connect with the secondary side terminal 33, and the relay terminal 5 and the branch wiring connection terminal 6 are formed of quick connection terminals. can be easily connected.
Furthermore, since the branch wiring connection terminal 6 is provided with the voltage detection hole 6b, the continuity test can be performed without using the voltage detection hole of the branch breaker 3 and without removing the branch wiring 8, which is convenient. .
In addition, since the wire insertion opening 13 is provided near the branch wiring connection terminal 6, the branch wiring 8 introduced from the back of the distribution board is connected to the branch wiring connection terminal 6 without routing inside the distribution board housing. It is possible, and there is no need to provide a separate routing space.

尚、分岐配線接続端子６を第１の群Ｇ１と第２の群Ｇ２とに分けて配置しているが、全ての分岐配線接続端子６を１列に配置しても良い。また、分岐配線接続端子６に接地端子を更に加えても良い。
また、基台１を分電盤ハウジングの一部を構成する部材として説明しているが、分電盤ハウジングの内部に配置される部材としても良い。 Although the branch wiring connection terminals 6 are divided into the first group G1 and the second group G2 and arranged, all the branch wiring connection terminals 6 may be arranged in one row. Also, a ground terminal may be added to the branch wiring connection terminal 6 .
Moreover, although the base 1 is described as a member forming part of the distribution board housing, it may be a member arranged inside the distribution board housing.
