Description
本発明は分電盤に関し、詳しくは分電盤に組み付けられたブレーカに引き込み線或いは分岐配線を接続する接続形態の改良に関する。 The present invention relates to a distribution board, and more specifically to an improved connection method for connecting drop wires or branch wiring to a breaker installed in a distribution board.
分電盤に組み付けられたブレーカは、主幹ブレーカ、分岐ブレーカの種類によらず、一次側端子或いは二次側端子の少なくとも一方が電線を挿入或いはネジ止めして接続される構成となっている。
この場合の電線の接続は、分電盤の背部に設けられた開口部から電線を分電盤内に引き込んだ後、接続対象のブレーカまで引き回して接続した（例えば、特許文献１参照）。
Regardless of the type of breaker, whether it is a main breaker or a branch breaker, the breaker assembled to the distribution board is configured so that at least one of the primary side terminal or secondary side terminal is connected by inserting or screwing in an electric wire.
In this case, the electric wires are connected by pulling them into the distribution board through an opening provided at the back of the distribution board, and then running them to the breaker to be connected (see, for example, Patent Document 1).
上記従来のブレーカへの電線接続形態は、分電盤背部に電線挿入或いは電線引き回しのための開口部を大きく形成しても、電線の接続はブレーカを組み付けた後に行われるため、組み付けられるブレーカで開口部の殆どが塞がれることになったため、電線の引き込み及び引き回しがし辛かった。
また、引き込んだ位置から接続先の回路遮断器が遠い位置にあったらその分電線を長くしなければならないため、電線の余長を多く確保する必要があった。
In the above-mentioned conventional wire connection configuration to the breaker, even if a large opening for inserting or routing the wire is formed on the back of the distribution board, the wire is connected after the breaker is assembled, so most of the opening is blocked by the assembled breaker, making it difficult to insert or route the wire.
Furthermore, if the circuit breaker to which the cable is connected is located far from the cable pull-in position, the cable must be made longer accordingly, so it was necessary to leave a lot of excess cable length.
そこで、本発明はこのような問題点に鑑み、ブレーカを組み付ける前の広い空間の中での電線の引き込み及び配線作業を可能とした分電盤を提供することを目的としている。 In light of these problems, the present invention aims to provide a distribution board that allows for wire pulling and wiring work in a large space before installing the breaker.
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が組み付けられた分電盤であって、分岐ブレーカの二次側端子を分岐配線に接続する際に介在させる分岐用コネクタを配置し、分岐用コネクタは、分岐ブレーカの二次側端子に接続される端子金具を有して、分岐ブレーカに装着される第１分岐ユニットと、分岐配線が接続される電線接続部を有して、分電盤のハウジングに取り付けられる第２分岐ユニットとから成り、第１分岐ユニットと第２分岐ユニットとは、端子金具と電線接続部との電気的接続を可能とする連結部をそれぞれ有し、分岐ブレーカに装着された第１分岐ユニットの連結部と、ハウジングに取り付けられた第２分岐ユニットの連結部とは、分岐ブレーカを分電盤に組み付けた際に互いに連結され、分岐ブレーカの二次側端子が分岐配線に接続されることを特徴とする。
この構成によれば、分岐配線の分岐ブレーカへの接続は、分岐用コネクタの分電盤ハウジングに取り付けられた第２分岐ユニットへ分岐配線を接続することで実施される。よって、分岐ブレーカを分電盤に組み付ける前の広い空間の中で分岐配線の接続作業を行うことができ、分岐配線の接続作業がし易い。
In order to solve the above problem, the invention of claim 1 is a distribution board in which a main breaker and multiple branch breakers are assembled, and a branch connector is arranged to be interposed when connecting the secondary terminal of the branch breaker to the branch wiring, and the branch connector comprises a first branch unit having terminal fittings connected to the secondary terminal of the branch breaker and attached to the branch breaker, and a second branch unit having an electric wire connection portion to which the branch wiring is connected and attached to the housing of the distribution board, and the first branch unit and the second branch unit each have connecting portions that enable electrical connection between the terminal fittings and the electric wire connection portion, and the connecting portion of the first branch unit attached to the branch breaker and the connecting portion of the second branch unit attached to the housing are connected to each other when the branch breaker is assembled to the distribution board, and the secondary terminal of the branch breaker is connected to the branch wiring.
With this configuration, the branch wiring is connected to the branch breaker by connecting the branch wiring to the second branch unit attached to the distribution board housing of the branch connector. This makes it possible to connect the branch wiring in a large space before assembling the branch breaker to the distribution board, making the branch wiring connection work easier.
請求項２の発明は、請求項１に記載の構成において、前記第１分岐ユニットの前記分岐ブレーカに接続する前記端子金具と、前記第２分岐ユニットの分岐配線を接続する前記電線接続部とは、同一方向を向いていることを特徴とする。
この構成によれば、端子金具と電線接続部とが同一方向であるため、電線接続部に接続する電線は、分岐ブレーカへ直接接続する方向とは逆方向に配設される。よって、分電盤背部から引き込んだ電線をスムーズに接続処理でき、従来のように分岐ブレーカ横の狭いスペースで電線を引き回して接続処理する必要がない。
尚、「同一方向」とは、正確な同一方向に加えて、ほぼ同一方向も含むものである。
The invention of claim 2 is characterized in that, in the configuration described in claim 1, the terminal fittings connected to the branch breaker of the first branch unit and the wire connection portion connecting the branch wiring of the second branch unit face in the same direction.
With this configuration, the terminal fittings and the wire connection parts are oriented in the same direction, so the wires connected to the wire connection parts are arranged in the opposite direction to the direction in which they would be directly connected to the branch breaker. This allows for smooth connection of the wires pulled in from the back of the distribution board, eliminating the need to route the wires through the narrow space next to the branch breaker as in the past.
The term "same direction" includes not only exactly the same direction but also almost the same direction.
請求項３の発明は、主幹ブレーカと複数の分岐ブレーカが組み付けられた分電盤であって、主幹ブレーカの一次側端子を引き込み線に接続する際に介在させる主幹用コネクタを配置し、主幹用コネクタは、主幹ブレーカの一次側端子に接続される端子金具を有して、主幹ブレーカに装着される第１主幹ユニットと、引き込み線が接続される電線接続部を有して、分電盤のハウジングに取り付けられる第２主幹ユニットとから成り、第１主幹ユニットと第２主幹ユニットとは、端子金具と電線接続部との電気的接続を可能とする連結部をそれぞれ有し、主幹ブレーカに装着された第１主幹ユニットの連結部と、ハウジングに取り付けられた第２主幹ユニットの連結部とは、主幹ブレーカを分電盤に組み付けた際に互いに連結され、主幹ブレーカの一次側端子が引き込み線に接続されることを特徴とする。
この構成によれば、引き込み線の主幹ブレーカへの接続は、主幹用コネクタの分電盤ハウジングに取り付けられた第２主幹ユニットへ引き込み線を接続することで実施される。よって、主幹ブレーカを分電盤に組み付ける前の広い空間の中で引き込み線の接続作業を行うことができ、引き込み線の接続作業がし易い。
The invention of claim 3 is a distribution board in which a main breaker and a plurality of branch breakers are assembled, and which is provided with a main connector that is interposed when connecting the primary terminal of the main breaker to a drop line, and which comprises a first main unit that has terminal fittings connected to the primary terminal of the main breaker and is attached to the main breaker, and a second main unit that has an electric wire connection portion to which the drop line is connected and is attached to the housing of the distribution board, and the first main unit and the second main unit each have connecting portions that enable electrical connection between the terminal fittings and the electric wire connection portion, and the connecting portion of the first main unit attached to the main breaker and the connecting portion of the second main unit attached to the housing are connected to each other when the main breaker is assembled to the distribution board, and the primary terminal of the main breaker is connected to the drop line.
With this configuration, the drop wire is connected to the main breaker by connecting it to the second main unit attached to the distribution board housing of the main connector. This allows the drop wire to be connected in a large space before the main breaker is installed in the distribution board, making the connection process easier.
請求項４の発明は、請求項３に記載の構成において、前記第１主幹ユニットの前記主幹ブレーカに接続する前記端子金具と、前記第２主幹ユニットの引き込み線を接続する前記電線接続部とは、同一方向を向いていることを特徴とする。
この構成によれば、端子金具と電線接続部とが同一方向であるため、電線接続部に接続する電線は、主幹ブレーカへ直接接続する方向とは逆方向に配設される。よって、分電盤背部から引き込んだ電線をスムーズに接続処理でき、従来のように主幹ブレーカ横の狭いスペースで電線を引き回して接続処理する必要がない。
The invention of claim 4 is characterized in that, in the configuration described in claim 3, the terminal fittings connected to the main breaker of the first main unit and the wire connection portion connecting the drop wire of the second main unit face in the same direction.
With this configuration, the terminal fittings and the wire connection parts are oriented in the same direction, so the wires connected to the wire connection parts are arranged in the opposite direction to the direction in which they would be directly connected to the main breaker. This allows for smooth connection of the wires pulled in from the back of the distribution board, eliminating the need to route the wires through the narrow space next to the main breaker as in the past.
本発明によれば、分岐配線の分岐ブレーカへの接続は、分岐用コネクタの分電盤ハウジングに取り付けられた第２分岐ユニットへ分岐配線を接続することで実施される。よって、分岐ブレーカを分電盤に組み付ける前の広い空間の中で分岐配線の接続作業を行うことができ、分岐配線の接続作業がし易い。
また、引き込み線の主幹ブレーカへの接続は、主幹用コネクタの分電盤ハウジングに取り付けられた第２主幹ユニットへ引き込み線を接続することで実施される。よって、主幹ブレーカを分電盤に組み付ける前の広い空間の中で引き込み線の接続作業を行うことができ、引き込み線の接続作業がし易い。
According to the present invention, the branch wiring is connected to the branch breaker by connecting the branch wiring to the second branch unit attached to the distribution board housing of the branch connector. This allows the branch wiring to be connected in a large space before the branch breaker is installed in the distribution board, making the branch wiring connection work easier.
In addition, the service line is connected to the main breaker by connecting it to the second main unit attached to the distribution board housing of the main connector. This allows the service line to be connected in a large space before the main breaker is installed in the distribution board, making the service line connection easy.
以下、本発明を具体化した実施の形態を、図面を参照して詳細に説明する。図１，２は本発明に係る分電盤の一例を示し、図１は分電盤の斜視図、図２はブレーカを組み付けた基台を分電盤のハウジングから分離した状態を示している。分電盤１のハウジング１０内には、主幹ブレーカ２と複数の分岐ブレーカ３が組み付けられている。
尚、分電盤の前面を塞ぐ蓋部材は省略してある。
[0016] An embodiment of the present invention will now be described in detail with reference to the drawings. Figures 1 and 2 show an example of a distribution board according to the present invention, with Figure 1 being a perspective view of the distribution board and Figure 2 showing a base on which breakers are mounted separated from the housing of the distribution board. A main breaker 2 and multiple branch breakers 3 are mounted within the housing 10 of the distribution board 1.
The cover member that covers the front of the distribution board is omitted.

The main connector 5 is composed of a first main unit 5a that is attached to the main breaker 2 and a second main unit 5b that is attached to the housing 10 of the distribution board 1.
そして、図２に示すように、分岐配線９はハウジング１０に取り付けられた第２分岐ユニット４ｂに接続される。また、引き込み線８はハウジング１０に取り付けられた第２主幹ユニット５ｂに接続される。この接続により、分電盤１への分岐配線９及び引き込み線８の接続は完了となる。 Then, as shown in Figure 2, the branch wiring 9 is connected to the second branch unit 4b attached to the housing 10. Furthermore, the service line 8 is connected to the second main unit 5b attached to the housing 10. This connection completes the connection of the branch wiring 9 and service line 8 to the distribution board 1.
ここで、基台１１に主幹ブレーカ２及び分岐ブレーカ３を組み付けたユニットＤを説明する。ユニットＤは、金属板からなる基台１１に主幹ブレーカ２、分岐ブレーカ３、主幹ブレーカ２と分岐ブレーカ３とを接続する銅バーから成る主幹バー１２が組み付けられている。但し、主幹バー１２は保護カバー１３に覆われている。 Here, we will explain unit D, which has a main breaker 2 and branch breakers 3 assembled to a base 11. Unit D has a main breaker 2, branch breakers 3, and a main bar 12 made of a copper bar that connects the main breaker 2 and branch breakers 3 assembled to a base 11 made of a metal plate. However, the main bar 12 is covered with a protective cover 13.
引き込み線８は、２つの電圧相（電圧極）Ｌ１，Ｌ２と中性相（中性極）Ｎを備えた単相３線式電路で構成されており、主幹ブレーカ２は一次側端子２１及び二次側端子２２は３端子で構成され、主幹バー１２は３本の銅バーで構成されている。
そして、分岐ブレーカ３の一次側端子３１はこの３つの銅バーのうちの特定の２本が選択されて接続される。３本の銅バーのうちの２本を選択することで、１００Ｖ／２００Ｖが選択されて２次側に接続された分岐配線９に出力される。
The service line 8 is composed of a single-phase three-wire circuit with two voltage phases (voltage poles) L1 and L2 and a neutral phase (neutral pole) N, and the main breaker 2 has three terminals, including a primary terminal 21 and a secondary terminal 22, and the main bar 12 is composed of three copper bars.
Two specific copper bars are selected and connected to the primary terminal 31 of the branch breaker 3. By selecting two of the three copper bars, 100V/200V is selected and output to the branch wiring 9 connected to the secondary side.
図３は、 図１の上段の分岐ブレーカ３の群を抜き出した図で、分岐ブレーカ３に接続されている分岐用コネクタ４の一部を成す第１分岐ユニット４ａを合わせて示している。但し、第１分岐ユニット４ａの１つは取り外した状態で示している。
図３に示すように、分岐ブレーカ３は、一次側端子３１が３つの凹部を設けて形成され、挿入した主幹バー１２を把持して接続するよう構成されている。尚、３つの凹部のうち２つに端子金具が配置されて主幹バー１２に接続される。
また、二次側端子３２は３端子を有しているが、使用しない端子は蓋部材３３で閉塞され、使用する２端子が露出するよう構成されている。この二次側端子３２は速結端子で構成されている。
3 is a diagram of the group of branch breakers 3 in the upper row of FIG. 1, and also shows the first branch units 4a that form part of the branch connectors 4 connected to the branch breakers 3. However, one of the first branch units 4a is shown in a detached state.
As shown in Figure 3, the branch breaker 3 has a primary terminal 31 formed with three recesses, which are configured to grip and connect to the inserted main bar 12. Terminal fittings are placed in two of the three recesses and connected to the main bar 12.
The secondary terminal 32 has three terminals, but the unused terminals are covered with a cover member 33, leaving the two used terminals exposed. The secondary terminal 32 is a quick-connect terminal.
尚、図３に示している第１分岐ユニット４ａを取り外した分岐ブレーカ３は、中性極Ｎの二次側端子３２が閉塞され、２つの電圧極Ｌ１，Ｌ２の二次側端子３２が使用される構成、即ち２００Ｖを分岐出力する構成となっている。対応する第１分岐ユニット４ａも、２つの電圧極Ｌ１，Ｌ２の二次側端子３２に接続されるように後述する端子金具４１が配置されている。 In the branch breaker 3 shown in Figure 3 with the first branch unit 4a removed, the secondary terminal 32 of the neutral pole N is blocked and the secondary terminals 32 of the two voltage poles L1 and L2 are used, i.e., the branch breaker is configured to branch out and output 200V. The corresponding first branch unit 4a also has terminal fittings 41, described below, arranged to connect to the secondary terminals 32 of the two voltage poles L1 and L2.
次に、分岐用コネクタ４を具体的に説明する。
図４は、分岐用コネクタ４の第１分岐ユニット４ａと第２分岐ユニット４ｂを分離した状態を示し、（ａ）は図１に示す角度からみた斜視図、（ｂ）は反対方向からみた斜視図である。また、図５は、第１分岐ユニット４ａの端子金具の位置を示し、（ａ）は第１電圧極Ｌ１と中性極Ｎの端子金具４１を備えた構成、（ｂ）は第２電圧極Ｌ２と中性極Ｎの端子金具４１を備えた構成を示している。
尚、図４では第１電圧極Ｌ１と中性極Ｎに接続する端子金具４１を備えた構成を示している。
Next, the branch connector 4 will be described in detail.
4A and 4B show the first and second branching units 4a and 4b of the branching connector 4 separated from each other, with (a) being a perspective view seen from the angle shown in FIG. 1 and (b) being a perspective view seen from the opposite direction. Also, Fig. 5A shows the positions of the terminal fittings of the first branching unit 4a, with (a) showing a configuration including terminal fittings 41 for the first voltage pole L1 and the neutral pole N, and (b) showing a configuration including terminal fittings 41 for the second voltage pole L2 and the neutral pole N.
4 shows a configuration including terminal fittings 41 connected to the first voltage pole L1 and the neutral pole N.
第１分岐ユニット４ａに設けられている端子金具４１は、分岐ブレーカ３の速結端子から成る二次側端子３２に接続可能な一対の棒状突起を有して形成されている。一方、第２分岐ユニット４ｂとの連結部４２は凹部を有して雌型に形成されている。
また、端子金具４１を設けた面と対峙する反対側の面には検電口４ｃを備えている。この検電口４ｃは端子金具４１毎に設けられ、対を成して設けられている。
The terminal fitting 41 provided on the first branching unit 4a is formed with a pair of rod-shaped protrusions that can be connected to the secondary terminal 32, which is a quick-connect terminal of the branch breaker 3. On the other hand, the connecting portion 42 with the second branching unit 4b is formed in a female shape with a recess.
Furthermore, a voltage detector 4c is provided on the surface opposite to the surface on which the terminal fittings 41 are provided. The voltage detector 4c is provided for each terminal fitting 41, and is provided in pairs.
このように、第１分岐ユニット４ａは分岐ブレーカ３毎に独立して形成されているが、第２分岐ユニット４ｂは図４に示すように第１分岐ユニット４ａとの連結部が複数列設され、１つの第２分岐ユニット４ｂで複数の分岐ブレーカ３に対応するよう形成されている。
第２分岐ユニット４ｂの連結部４３は凸部を有して雄型に形成され、この凸部が連結金具４３ａから成り、第１分岐ユニット４ａの凹部に形成された連結部４２に挿入されて連結され、電気的接続がなされる。また、個々の連結部４３に合わせて、分岐配線９を接続する電線接続部４４を備えている。
In this way, the first branching unit 4a is formed independently for each branch breaker 3, but the second branching unit 4b has multiple rows of connecting portions with the first branching unit 4a as shown in Figure 4, and is formed so that one second branching unit 4b can correspond to multiple branch breakers 3.
The connecting portion 43 of the second branching unit 4b is formed in a male shape with a protrusion, and this protrusion is made of a connecting metal fitting 43a, which is inserted into the connecting portion 42 formed in the recess of the first branching unit 4a to connect and establish an electrical connection. In addition, each connecting portion 43 is provided with an electric wire connecting portion 44 for connecting the branch wiring 9.
図６，７は、第１分岐ユニット４ａの内部構造を示し、図６（ａ）は検電口４ｃ配置面を正面とした平面図、図６（ｂ）はＡ－Ａ線断面図、図６（ｃ）はＢ－Ｂ線断面図、図７は第１分岐ユニット４ａの内部に配設した電路金具４５を抜き出した図である。
図６、７に示すように、対を成して形成されている連結部４２と端子金具４１とは、対応する極が内部で２本の電路金具４５にそれぞれ連結されている。連結部４２は、挿入された第２分岐ユニット４ｂの凸部を構成する連結金具４３ａを把持する把持金具４２ａを有し、電路金具４５は途中に検電口４ｃに露出する検電金具４５ａを備えている。
Figures 6 and 7 show the internal structure of the first branching unit 4a, with Figure 6(a) being a plan view with the surface where the voltage detector 4c is located facing forward, Figure 6(b) being a cross-sectional view along line A-A, Figure 6(c) being a cross-sectional view along line B-B, and Figure 7 being a view of the electrical circuit fittings 45 arranged inside the first branching unit 4a.
6 and 7, the corresponding poles of the paired connecting portion 42 and terminal fitting 41 are internally connected to two electric circuit fittings 45. The connecting portion 42 has a gripping fitting 42a that grips the connecting fitting 43a that forms the protrusion of the inserted second branching unit 4b, and the electric circuit fitting 45 has an electric detector fitting 45a that is exposed in the electric detector port 4c.
一方、第２分岐ユニット４ｂは、図４に示すように分岐配線９を接続する電線接続部４４を有し、電線接続部４４を配置した面と第１分岐ユニット４ａと接続する連結部４３を配置した面とは略直交するように形成されている。即ち、第１分岐ユニット４ａの端子金具４１の突出方向と、第２分岐ユニット４ｂの電線接続部４４とは、略同一方向を向いている。そして、連結部４３の連結金具４３ａと電線接続部４４とは、それぞれ対を成しており、対応する極同士は内部で連結されている。
電線接続部４４は、挿入された電線（分岐配線９）を挟持して電気的な接続が成される速結端子（図示せず）となっている。
4, the second branch unit 4b has a wire connection portion 44 for connecting the branch wiring 9, and is formed so that the surface on which the wire connection portion 44 is arranged is substantially perpendicular to the surface on which the linking portion 43 for connecting to the first branch unit 4a is arranged. That is, the protruding direction of the terminal fittings 41 of the first branch unit 4a and the wire connection portion 44 of the second branch unit 4b face substantially the same direction. The linking fittings 43a of the linking portion 43 and the wire connection portion 44 each form a pair, and corresponding poles are internally linked.
The electric wire connection portion 44 is a quick-connect terminal (not shown) that clamps the inserted electric wire (branch wiring 9) to establish an electrical connection.
この第２分岐ユニット４ｂは、分岐ブレーカ３のハウジング１０内の組み付け位置に合わせて取り付けられる。詳しくは、分岐ブレーカ３に装着されている第１分岐ユニット４ａの位置に合わせて、この第１分岐ユニット４ａに連結されるようハウジング１０の所定部位に取り付けられる。その際、電線接続部４４は、組み付けられる分岐ブレーカ３に向けて配置され、分岐ブレーカ３の二次側端子３２の接続方向とは逆の方向から分岐配線９が第２分岐ユニット４ｂに接続される。
そして、分岐ブレーカ３を分電盤１のハウジング１０に組み付けた際に、双方の連結部４２，４３同士が連結されて分岐ブレーカ３に分岐配線９が接続される。
The second branch unit 4b is attached to the housing 10 of the branch breaker 3 in accordance with its installation position. More specifically, the second branch unit 4b is attached to a predetermined portion of the housing 10 so as to be connected to the first branch unit 4a, aligned with the position of the first branch unit 4a attached to the branch breaker 3. At this time, the wire connection portion 44 is positioned facing the branch breaker 3 to be installed, and the branch wiring 9 is connected to the second branch unit 4b from the direction opposite to the connection direction of the secondary terminals 32 of the branch breaker 3.
When the branch breaker 3 is assembled into the housing 10 of the distribution board 1 , the connecting portions 42 , 43 are connected to each other, and the branch wiring 9 is connected to the branch breaker 3 .
このように、分岐配線９の分岐ブレーカ３への接続は、分岐用コネクタ４の分電盤１のハウジング１０に取り付けられた第２分岐ユニット４ｂへ分岐配線９を接続することで実施される。よって、分岐ブレーカ３を分電盤１に組み付ける前の広い空間の中で、分岐配線９の接続作業を行うことができ、分岐配線９の接続作業がし易い。
また、端子金具４１と電線接続部４４とが同一方向であるため、電線接続部４４に接続する分岐配線９である電線は、分岐ブレーカ３へ直接接続する方向とは逆方向に配設される。よって、分電盤１の背部から引き込んだ電線をスムーズに接続処理でき、従来のように分岐ブレーカ３横の狭いスペースで電線を引き回して接続処理する必要がない。
In this way, the branch wiring 9 is connected to the branch breaker 3 by connecting the branch wiring 9 to the second branch unit 4b attached to the housing 10 of the distribution board 1 of the branch connector 4. Therefore, the connection work of the branch wiring 9 can be performed in a large space before the branch breaker 3 is assembled to the distribution board 1, making the connection work of the branch wiring 9 easy.
Furthermore, since the terminal fittings 41 and the electric wire connection parts 44 are oriented in the same direction, the electric wires that are the branch wiring 9 connected to the electric wire connection parts 44 are arranged in the opposite direction to the direction in which they are directly connected to the branch breaker 3. Therefore, the electric wires that are pulled in from the back of the distribution board 1 can be smoothly connected, and there is no need to route the electric wires in the narrow space next to the branch breaker 3 for connection, as in the conventional case.
尚、上記実施形態では、第１分岐ユニット４ａと第２分岐ユニット４ｂとの連結を、凹部と凸部で構成して挿入接続する構成としているが、連結部４２，４３同士の連結形態は他の形態でも良く、例えば互いにネジ締め端子としてネジ締めにより連結しても良い。
また、分岐ブレーカ３の二次側端子３２が速結端子では無く、ネジ締めにより接続する形態であれば、第１分岐ユニット４ａの端子金具４１もネジ締め可能な端子形状となる。
また、第２分岐ユニット４ｂを、複数の第１分岐ユニット４ａを接続する構成としているが、第１分岐ユニット４ａと同様に分岐ブレーカ３毎に独立させても良い。
In the above embodiment, the connection between the first branch unit 4a and the second branch unit 4b is configured by inserting and connecting using a concave portion and a convex portion, but the connection between the connecting portions 42 and 43 may be in other forms, for example, they may be connected to each other by screwing them together as screw-fastened terminals.
Furthermore, if the secondary terminal 32 of the branch breaker 3 is not a quick-connect terminal but is connected by screwing, the terminal fitting 41 of the first branch unit 4a also has a terminal shape that can be fastened by screws.
Furthermore, the second branching unit 4b is configured to connect a plurality of first branching units 4a, but may be configured to be independent for each branch breaker 3, similar to the first branching units 4a.
次に、主幹ブレーカ２に適用される主幹用コネクタ５を説明する。図８は図１の主幹ブレーカ２と主幹用コネクタ５の第１主幹ユニット５ａを抜き出した斜視図で、第１主幹ユニット５ａを分離して示している。また、図９は分離した主幹用コネクタ５を示し、（ａ）は図８に示す角度から見た斜視図、（ｂ）は反対方向から見た斜視図である。
主幹ブレーカ２は、単相３線式電路に使用される３端子で構成され、一次側端子２１及び二次側端子２２はネジ締め構造の端子となっている。但し、図ではネジを省略している。そして、一次側端子２１に主幹用コネクタ５の第１主幹ユニット５ａが接続される。尚、二次側端子２２は主幹バー１２が接続される。
Next, we will explain the trunk connector 5 that is applied to the trunk breaker 2. Figure 8 is a perspective view of the trunk breaker 2 and the first trunk unit 5a of the trunk connector 5 in Figure 1, with the first trunk unit 5a shown separated. Figure 9 also shows the separated trunk connector 5, with (a) being a perspective view seen from the angle shown in Figure 8 and (b) being a perspective view seen from the opposite direction.
The main breaker 2 is composed of three terminals used in a single-phase three-wire circuit, with the primary terminal 21 and secondary terminal 22 being screw-fastened terminals. The screws are omitted in the figure. The first main unit 5a of the main connector 5 is connected to the primary terminal 21. The main bar 12 is connected to the secondary terminal 22.
第１主幹ユニット５ａは、主幹ブレーカ２の一次側端子２１に接続する３つの端子金具５１を有し、図示しない端子ネジで連結される。そして、後端に第２主幹ユニット５ｂと連結する連結部５２を備えている。この連結部５２は凹部を有して雌型に形成され、内部に第２主幹ユニット５ｂの後述する連結金具５３ａを把持する把持金具５２ａを有し、把持金具５２ａと端子金具５１とがユニット内で連結されている。 The first main unit 5a has three terminal fittings 51 that connect to the primary terminals 21 of the main breaker 2 and are connected with terminal screws (not shown). It also has a connecting portion 52 at its rear end that connects to the second main unit 5b. This connecting portion 52 is formed in a female shape with a recess, and has a gripping fitting 52a inside that grips the connecting fitting 53a (described below) of the second main unit 5b, and the gripping fitting 52a and terminal fitting 51 are connected within the unit.
一方、第２主幹ユニット５ｂは、第１主幹ユニット５ａと連結する連結部５３と、引き込み線が連結される電線接続部５４とを備えている。連結部５３は３つの連結金具５３ａが突出形成され、雄型に形成されている。連結部５３と電線接続部５４とは直交する向きで配置され、双方がユニット内で連結されている。
即ち、第１主幹ユニット５ａの端子金具５１の突出方向と、第２主幹ユニット５ｂの電線接続部５４とは、略同一方向を向いている。
On the other hand, the second main unit 5b has a connecting portion 53 that connects to the first main unit 5a and an electric wire connection portion 54 to which the drop wire is connected. The connecting portion 53 has three protruding connecting fittings 53a and is formed as a male type. The connecting portion 53 and the electric wire connection portion 54 are arranged in a perpendicular direction and are connected to each other within the unit.
That is, the protruding direction of the terminal fittings 51 of the first main unit 5a and the wire connecting portion 54 of the second main unit 5b are oriented in substantially the same direction.
この第２主幹ユニット５ｂは、主幹ブレーカ２のハウジング１０内の組み付け位置に合わせて、所定部位に取り付けられる。即ち、組み付けられた主幹ブレーカ２に装着されている第１主幹ユニット５ａの位置に合わせて、第１主幹ユニット５ａに連結されるようハウジング１０の所定部位に取り付けられる。尚、その際、電線接続部５４は、主幹ブレーカ２の背部に向けて、ハウジング１０の取付面に平行に配置され、主幹ブレーカ２の一次側端子２１の接続方向とは逆の方向から引き込み線８が接続される。
そして、主幹ブレーカ２を分電盤１のハウジング１０に組み付けた際に、双方の連結部５２，５３同士が連結されて、主幹ブレーカ２に引き込み線８が接続される。
This second main unit 5b is attached to a predetermined location in accordance with the assembly position within the housing 10 of the main breaker 2. That is, it is attached to a predetermined location on the housing 10 so as to be connected to the first main unit 5a, in accordance with the position of the first main unit 5a attached to the assembled main breaker 2. At this time, the wire connection portion 54 is positioned parallel to the mounting surface of the housing 10, facing the back of the main breaker 2, and the drop wire 8 is connected from the direction opposite to the connection direction of the primary terminal 21 of the main breaker 2.
When the main breaker 2 is assembled into the housing 10 of the distribution board 1 , the connecting portions 52 , 53 of both are connected to each other, and the lead-in wire 8 is connected to the main breaker 2 .
このように、引き込み線８の主幹ブレーカ２への接続は、主幹用コネクタ５の分電盤１のハウジング１０に取り付けられた第２主幹ユニット５ｂへ引き込み線８を接続することで実施される。よって、主幹ブレーカ２を分電盤１に組み付ける前の広い空間の中で、引き込み線８の接続作業を行うことができ、引き込み線８の接続作業がし易い。
また、端子金具５１と電線接続部５４とが同一方向であるため、電線接続部５４に接続する引き込み線８である電線は、主幹ブレーカ２へ直接接続する方向とは逆方向に配設される。よって、分電盤１の背部から引き込んだ電線をスムーズに接続処理でき、従来のように主幹ブレーカ２横の狭いスペースで電線を引き回して接続処理する必要がない。
In this way, the connection of the service line 8 to the main breaker 2 is achieved by connecting the service line 8 to the second main unit 5b attached to the housing 10 of the distribution board 1 of the main connector 5. Therefore, the connection work of the service line 8 can be performed in a large space before the main breaker 2 is assembled to the distribution board 1, making the connection work of the service line 8 easy.
Furthermore, since the terminal fittings 51 and the electric wire connection parts 54 are oriented in the same direction, the electric wires that are the lead-in wires 8 that connect to the electric wire connection parts 54 are arranged in the opposite direction to the direction in which they are directly connected to the main breaker 2. Therefore, the electric wires that are led in from the back of the distribution board 1 can be smoothly connected, and there is no need to route the electric wires in the narrow space next to the main breaker 2 and connect them as in the conventional case.
尚、上記実施形態では、第１主幹ユニット５ａと第２主幹ユニット５ｂとの連結を、凹部と凸部で構成して挿入接続する構成としているが、連結部５２，５３同士の連結形態は他の形態でも良く、例えば互いにネジ締め端子としてネジ締めにより連結しても良い。 In the above embodiment, the first main unit 5a and the second main unit 5b are connected by inserting a recess and a protrusion into each other. However, the connection between the connecting portions 52 and 53 may be in other forms. For example, they may be connected to each other by screwing together as screw terminals.
