Description

本発明は、外部から引き込んだ電源線を一旦送り端子台に接続して、この送り端子台から一次送りのブレーカと主幹ブレーカに配線を行う分電盤に関するものである。   The present invention relates to a distribution board for temporarily connecting a power line drawn from outside to a feed terminal block and wiring from the feed terminal block to a primary feed breaker and a main breaker.

送り端子台に一旦電源線を接続して、この送り端子台から一次送りブレーカと主幹ブレーカに配線を行う従来の分電盤は、送り端子台として、電源側に３極の接続端子を同一高さとして備えて、負荷側に該接続端子のうち電圧相である両側の接続端子と接続した２つの接続バーを備えた構造のものを搭載して該接続バーを２線分の大きさの一次送りブレーカの端子に接続するものであった。（例えば、特許文献１参照）   The conventional distribution board that connects the power line to the feed terminal block and then connects the primary feed breaker and the main breaker from this feed terminal block has the same height as the feed terminal block. In addition, a load having a structure having two connection bars connected to the connection terminals on both sides of the voltage phase among the connection terminals is mounted on the load side, and the connection bar is a primary size of two lines. It was connected to the terminal of the feed breaker. (For example, see Patent Document 1)

ところが、これは送り端子台の電源側を主幹ブレーカと接続する際に、３つの接続端子が同一高さであるため、同一高さにおいて３本の中継用電線を引き回さなければならず大きな配線スペースが必要で、分電盤をその分大きくする必要であった。   However, when connecting the power supply side of the feed terminal block to the main breaker, since the three connection terminals have the same height, three relay wires must be routed at the same height. Wiring space was required, and the distribution board had to be enlarged accordingly.

特開２００３−１７１５６公開公報Japanese Patent Laid-Open No. 2003-17156

本発明は前記のような従来の問題点を解決して、送り端子台の電源側と主幹ブレーカとを接続するための配線スペースを小さくすることができ、分電盤を小型化できる分電盤を提供するものである。   The present invention solves the conventional problems as described above, and can reduce the wiring space for connecting the power supply side of the feed terminal block and the main breaker, and the distribution board can be downsized. Is to provide.

本発明の分電盤は、３極の端子座受部のうち両側の２極の端子座受部と中央の１極の端子座受部の高さを異ならせて並設した送り端子台の一方側に３極の電源線を接続するとともに、主幹ブレーカへの３極の中継用電線を接続し、また、送り端子台の他方側に両側の２極の端子座受部の端子板を延出して一次送りブレーカに接続したことを特徴とするものを基本の発明とする。   The distribution board according to the present invention is a feed terminal block provided in parallel with the heights of the two-pole terminal seat receiving portions on both sides of the three-pole terminal seat receiving portions being different from the height of the central one-pole terminal seat receiving portion. Connect a 3-pole power line to one side, connect a 3-pole relay cable to the main breaker, and extend the terminal board of the 2-pole terminal seats on both sides to the other side of the feed terminal block. A basic invention is characterized in that it is connected to a primary feed breaker.

また、この発明において、送り端子台の他方側の下方に係止用脚板部を延設して、該係止用脚板部の先端に一次送りブレーカのケースの電源側に設けた係止部を係合させて、該一次送りブレーカを分電盤に固定することが好ましい。   Further, in this invention, a locking leg plate portion is provided below the other side of the feed terminal block, and a locking portion provided on the power source side of the case of the primary feed breaker is provided at the tip of the locking leg plate portion. It is preferable to engage and fix the primary feed breaker to the distribution board.

前記した本発明の分電盤は、送り端子台が３極の端子座受部のうち両側の２極の端子座受部と中央の１極の端子座受部の高さを異ならせて並設したもので、一方側に３極の電源線を接続するとともに、主幹ブレーカへの３極の中継用電線を接続したものであるから、主幹ブレーカへ接続する３極の中継用電線は両側の２極の端子座受部と中央の１極の端子座受部に接続したものを高さの異なるところで引き回すので上下に重合させることができ平面的なスペースを大きくとる必要がないのでその分分電盤を小型化することができるものである。   In the distribution board according to the present invention described above, the feed terminal block is arranged in parallel with the height of the two-pole terminal seat receiving portion on the both sides of the three-pole terminal seat receiving portion being different from the height of the central one-pole terminal seat receiving portion. Because it has a three-pole power line connected to one side and a three-pole relay cable to the main breaker, the three-pole relay cable connected to the main breaker Since the two-pole terminal seat receiving part and the one-pole terminal seat receiving part connected at the center are routed at different heights, they can be superposed up and down, so there is no need for a large plane space. The electric panel can be reduced in size.

また、送り端子台の他方側の下方に係止用脚板部を延設して、該係止用脚板部の先端に一次送りブレーカのケースの電源側に設けた係止部を係合させて、該一次送りブレーカを分電盤に固定するものとすると、一次送りブレーカを交換する際に、一次送りブレーカの端子部への端子座からの延出部のねじ止めを外した後に、該一次送りブレーカの負荷側の分電盤に対する固定を解いて、一次送りブレーカを負荷側にスライドすることにより係止部が係止用脚板部の先端との係止を解除するとともに延出部も一次送りブレーカから離脱するので端子座からの延出部を送り端子台から外すことなく一次送りブレーカを分電盤から取り外すことができる。そして、交換する新たな一次送りブレーカは前記と逆の手順により取り付ければよいものである。   Also, a locking leg plate portion is extended below the other side of the feed terminal block, and a locking portion provided on the power supply side of the case of the primary feed breaker is engaged with the tip of the locking leg plate portion. When the primary feed breaker is fixed to the distribution board, when the primary feed breaker is replaced, the primary feed breaker is unscrewed from the terminal seat to the terminal portion of the primary feed breaker, and then the primary feed breaker is removed. Unlock the feed breaker from the load-side distribution board and slide the primary feed breaker to the load side to release the latching part from the tip of the latching leg plate and the extension part to the primary. Since it is detached from the feed breaker, the primary feed breaker can be removed from the distribution board without removing the extension from the terminal seat from the feed terminal block. The new primary feed breaker to be replaced may be attached by the reverse procedure.

次に、本発明の好ましい実施の形態を図に基づき説明する。
図１はカバーを外して示す本発明に係る分電盤の全体図である。１は外部から分電盤ケース１００内に引き込んだ２本の電圧線２ａ（Ｌ１）、２ｂ（Ｌ２）と１本の中性線２ｃ(Ｎ)の３本の電源線２ａ、２ｂ、２ｃと接続する送り端子台、３は一次送り端子台１の２つの極すなわち図示のものは電圧相（Ｌ１、Ｌ２）と接続する２００Ｖ配線用の一次送りブレーカである。 Next, a preferred embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an overall view of a distribution board according to the present invention with the cover removed. Reference numeral 1 denotes three power lines 2a, 2b, 2c, which are two voltage lines 2a (L1), 2b (L2) and one neutral line 2c (N) drawn into the distribution board case 100 from the outside. The feed terminal block 3 to be connected is the two poles of the primary feed terminal block 1, that is, the one shown in the figure is a primary feed breaker for 200V wiring connected to the voltage phase (L1, L2).

４は主幹ブレーカであり、該主幹ブレーカ４の３相の電源側端子には送り端子台１に接続した２本の電圧線２ａ（Ｌ１）、２ｂ（Ｌ２）と１本の中性線２ｃ(Ｎ)に該送り端子台１において接続した３本の中継用電線５ａ、５ｂ、５ｃが接続されている。そして、前記主幹ブレーカ４の側方には負荷側端子に接続した２本の電圧相と１本の中性相の３本の分岐用母線バー６のうち一方の電圧相と中性相と接続して１００Ｖ配線、両電圧相同士に接続して２００Ｖ配線を行う多数の分岐用ブレーカ７が配設してある。   Reference numeral 4 denotes a main breaker. Two voltage lines 2 a (L 1), 2 b (L 2) connected to the feed terminal block 1 and one neutral line 2 c ( N), three relay wires 5a, 5b, 5c connected in the feed terminal block 1 are connected. Further, on the side of the main breaker 4, one voltage phase and one neutral phase of the two branch bus bars 6 of two voltage phases connected to the load side terminal and one neutral phase are connected to the neutral phase. In addition, a number of branch breakers 7 are arranged to perform 100V wiring and 200V wiring by connecting both voltage phases.

前記送り端子台１は、図３に示すように３極の端子座受部１１ａ、１１ｂ、１１ｃのうち両側の２極の端子座受部１１ａ、１１ｂと中央の１極の端子座受部１１ｃの高さを異ならせて並設したものである。そして、図示のものは、両側の２つの端子座受部１１ａ、１１ｂを電圧相（Ｌ１、Ｌ２）の電源線２ａ、２ｂと中央の１つの端子座受部１１ｃを中性相（Ｎ）の電源線２ｃと接続するものとして、該送り端子台１は端子座受部１１ａ、１１ｂ、１１ｃの一方側に端子座１２ａ、１２ｂ、１２ｃに端子ネジ１３をもって外部から２本の電圧線２ａ（Ｌ１）、２ｂ（Ｌ２）と１本の中性線２ｃ(Ｎ)を接続するとともに、主幹ブレーカ４への３本の中継用電線５ａ、５ｂ、５ｃを接続している。また、該送り端子台１の他方側に電圧相の端子座受部１１ａ、１１ｂの端子座１２ａ、１２ｂからの延出部として形成した接続バー１４ａ、１４ｂを一次送りブレーカ３の電源側端子部３ａ、３ｂに接続して２００Ｖの電力機器に対応するものとしている。なお、一次送りブレーカ３を１００Ｖの電気機器に配線する場合には、一次送りブレーカ３の電源側端子部３ａ、３ｂに接続する送り端子台の両側の端子座受部１１ａ、１１ｂの一方に中性相（Ｎ）の電源線２ｃを接続して他方の電圧線を接続バーの無い中央の端子座受部１１ｃに接続すればよいものである。なお、この場合主幹ブレーカ４の３極の電源側端子には対応した電源線を接続するものとする。   As shown in FIG. 3, the feed terminal block 1 has two pole terminal seat receiving portions 11a, 11b on both sides of the three pole terminal seat receiving portions 11a, 11b, 11c and a central one pole terminal seat receiving portion 11c. Are arranged side by side with different heights. In the illustrated example, the two terminal seat receiving portions 11a and 11b on both sides are connected to the power supply lines 2a and 2b in the voltage phase (L1, L2) and the one terminal seat receiving portion 11c in the center to the neutral phase (N). As the connection to the power supply line 2c, the feed terminal block 1 has two voltage lines 2a (L1 from the outside with terminal screws 12 on the terminal seats 12a, 12b and 12c on one side of the terminal seat receiving portions 11a, 11b and 11c. ) 2b (L2) and one neutral wire 2c (N) are connected, and three relay wires 5a, 5b, 5c to the main breaker 4 are connected. Further, connecting bars 14a and 14b formed as extending portions from the terminal seats 12a and 12b of the voltage phase terminal seats 11a and 11b on the other side of the feed terminal block 1 are connected to the power supply side terminal portions of the primary feed breaker 3. 3a and 3b are connected to support 200V power equipment. When the primary feed breaker 3 is wired to a 100 V electrical device, it is placed in one of the terminal seat receiving portions 11a and 11b on both sides of the feed terminal block connected to the power supply side terminal portions 3a and 3b of the primary feed breaker 3. It is only necessary to connect the power line 2c of the sex phase (N) and connect the other voltage line to the central terminal seat 11c having no connection bar. In this case, a corresponding power supply line is connected to the three-pole power supply side terminal of the main breaker 4.

前記したとおり、送り端子台１が３極の端子座受部１１ａ、１１ｂ、１１ｃのうち両側の２極の端子座受部１１ａ、１１ｂと中央の１極の端子座受部１１ｃの高さを異ならせて並設したもので、一方側に３極の電源線である２つの電圧線２ａ（Ｌ１）、２ｂ（Ｌ２）と１つの中性線２ｃ(Ｎ)を接続するとともに、主幹ブレーカ４への３極の中継用電線５ａ、５ｂ、５ｃを接続したものであるから、主幹ブレーカ４へ接続する３極の中継用電線５ａ、５ｂ、５ｃは両側の２極の端子座受部１１ａ、１１ｂと中央の１極の端子座受部１１ｃに接続したものを高さの異なるところで引き回すので図２に示すように上下に重合させることができ平面的なスペースを広くとる必要がなくその分分電盤を小型化することができるものである。   As described above, the feed terminal block 1 has the heights of the two-pole terminal seat receiving portions 11a, 11b and the central one-pole terminal seat receiving portion 11c of the three-pole terminal seat receiving portions 11a, 11b, 11c. Two voltage lines 2a (L1), 2b (L2), which are three-pole power supply lines, and one neutral line 2c (N) are connected to one side, and the main breaker 4 Since the three-pole relay wires 5a, 5b, and 5c are connected to the main breaker 4, the three-pole relay wires 5a, 5b, and 5c are connected to the two-pole terminal seat receiving portions 11a on both sides, Since the one connected to the terminal seat receiving portion 11c of 11b and the central one pole is drawn around at different heights, it can be superposed up and down as shown in FIG. The electric panel can be reduced in size.

また、図３―図４に示す実施例の１のように前記接続バー１４ａ、１４ｂと送り端子台１の基台１０上においては端子座受部１１ａ、１１ｂの上面にフラット状に続かせる形状として曲げ加工を不要なものとしている。このように接続バー１４ａ、１４ｂの形状をフラット状としても、前記したとおり両側の２つの電圧相とした端子座受部１１ａ、１１ｂを高く、中央に１つの中性相とした端子座受部１１ｃを低く形成したものであるから、中央の端子座受部１１ｃは端子座１２ｃの固定を接続バー１４ａ、１４ｂとの絶縁を確保して行うことができるものであり、さらに、接続バー１４ａ、１４ｂは端子座１２ｃが障害とならず基端側から内よりに形成でき幅を大きくすることが可能になり容量の大きな一次送りブレーカ３にも対応できるものである。   Further, as in the first embodiment shown in FIGS. 3 to 4, the connection bars 14a and 14b and the base 10 of the feed terminal block 1 have a shape that is flattened on the upper surfaces of the terminal seat receiving portions 11a and 11b. As a result, bending is unnecessary. Thus, even if the shape of the connection bars 14a and 14b is flat, as described above, the terminal seat receiving portions 11a and 11b having two voltage phases on both sides are high and the terminal seat receiving portion has one neutral phase in the center. Since 11c is formed low, the central terminal seat receiving portion 11c can secure the terminal seat 12c while ensuring insulation from the connection bars 14a, 14b. Further, the connection bar 14a, No. 14b can be formed from the base end side to the inside without causing the terminal seat 12c to become an obstacle, so that the width can be increased and the primary feed breaker 3 having a large capacity can be accommodated.

また、一次送りブレーカ３の電源側端子部３ａ、３ｂに接続する接続バー１４ａ、１４ｂは両側の端子座受部１１ａ、１１ｂの端子座１２ａ、１２ｂから延設して一体とすることにより、接続バー１４ａ、１４ｂは左右対称となり、同一形状のものを一種類製造して左右反転して使用すればよいので製造コストが削減できるものである。また、接続バー１４ａ、１４ｂは端子座受部１１ａ、１１ｂの一方側に螺合する端子ネジ１３をもって取り付けるものとしているので、基台１０の大きさを小さくできるものである。なお、接続バー１４ａ、１４ｂを端子板１２ａ、１２ｂと一体に形成してもよい。   Further, the connection bars 14a and 14b connected to the power supply side terminal portions 3a and 3b of the primary feed breaker 3 extend from the terminal seats 12a and 12b of the terminal seat receiving portions 11a and 11b on both sides to be connected together. The bars 14a and 14b are left-right symmetric, and it is only necessary to manufacture one type of the same shape and use it by turning it left and right, so that the manufacturing cost can be reduced. Moreover, since the connection bars 14a and 14b are attached with the terminal screw 13 screwed to one side of the terminal seat receiving portions 11a and 11b, the size of the base 10 can be reduced. Note that the connection bars 14a and 14b may be formed integrally with the terminal plates 12a and 12b.

また、送り端子台１は、図５−図１０に示す実施例の２のように基台１０を下部基台部１０ａと上部基台部１０ｂとに分割できるものとして、下部基台部１０ａは中央の上面を端子座受部１１ｃに形成してその両側を連結部に形成したものであり、また、上部基台部１０ｂは両側に端子座受部１１ａ、１１ｂを中央前隔壁部１５により連結して形成したものである。そして、下部基台部１０ａと上部基台部１０ｂを重ね合わせて連結することにより、３極の端子座受部１１ａ、１１ｂ、１１ｃのうち両側の２極の端子座受部１１ａ、１１ｂと中央の１極の端子座受部１１ｃの高さを異ならせて並設した送り端子台１となる。このように基台１０を下部基台部１０ａと上部基台部１０ｂとに分割できるものとすると、高さの異なる種々の下部基台部１０ａを用意して同じ上部基台部１０ｂと組み合わせることにより、高さの異なる一次送りのブレーカに対応できる種々の送り端子台を提供することができて製造コストを安くすることができる。   Further, the feed terminal block 1 can divide the base 10 into a lower base portion 10a and an upper base portion 10b as in the second embodiment shown in FIGS. 5 to 10, and the lower base portion 10a The center upper surface is formed in the terminal seat receiving portion 11c and both sides thereof are formed in the connecting portion, and the upper base portion 10b is connected to the terminal seat receiving portions 11a and 11b on both sides by the central front partition wall portion 15. Formed. Then, the lower base portion 10a and the upper base portion 10b are overlapped and connected to each other so that the two-pole terminal seat receiving portions 11a, 11b, and 11c on both sides are centered on the center. This is a feed terminal block 1 arranged in parallel with different heights of the terminal seat receiving portions 11c of one pole. When the base 10 can be divided into the lower base portion 10a and the upper base portion 10b as described above, various lower base portions 10a having different heights are prepared and combined with the same upper base portion 10b. Thus, it is possible to provide various feed terminal blocks that can correspond to the primary feed breakers having different heights, and the manufacturing cost can be reduced.

さらに、送り端子台１を図１１―図１４に示す実施例の３及び図１５―図１７に示す実施例の４のような電源側の端子３ａ、３ｂの高さを異ならせた一次送りのブレーカ３に対応できるものとするものにあっては、この一次送りのブレーカ３の端子３ａ、３ｂに接続する両側の２つの端子座受部１１ａ、１１ｂの高さを端子３ａ、３ｂの高さの中間に合わせた構造を採用する。そして、接続バー１４ａ、１４ｂは送り端子台１側の接続片部１４１と一次送りのブレーカ３側の接続片部１４２との間の連結板部１４３を傾斜させた構成とすることにより、接続バー１４ａ、１４ｂを同一形状のものを反転させることにより対応でき製造コストを安くすることができる。   Further, in the feed terminal block 1, the primary feeds 3a and 3b on the power source side having different heights as in the third embodiment shown in FIGS. 11 to 14 and the fourth embodiment shown in FIGS. In the case where the breaker 3 can be used, the heights of the two terminal seat receiving portions 11a and 11b on both sides connected to the terminals 3a and 3b of the primary feed breaker 3 are set to the heights of the terminals 3a and 3b. Adopt a structure that matches the middle. The connecting bars 14a and 14b are formed by inclining the connecting plate part 143 between the connecting piece part 141 on the feed terminal block 1 side and the connecting piece part 142 on the primary feed breaker 3 side. 14a and 14b can be dealt with by reversing the same shape, and the manufacturing cost can be reduced.

なお、図示のものは、一次送りのブレーカ３を２基並設したものであるので、接続バー１４ａ、１４ｂは一次送りのブレーカ３側の接続片部１４２を二股状として２つ設けているが、３基並設したものにあっては三股状として３つ設けたり、１基の場合には接続片部１４２を１つとすることは勿論である。   Since the illustrated one has two primary feed breakers 3 arranged side by side, the connection bars 14a and 14b are provided with two connection pieces 142 on the primary feed breaker 3 side in a bifurcated shape. Of course, in the case of three units arranged side by side, three are provided in a trifurcated shape, and in the case of one unit, one connection piece 142 is provided.

また、図１４に示すように、一次送りブレーカ３はケース３１の電源側と負荷側の下方に設けた凹状の係止部３１ａ、３１ａに取付用金具８を係合させて、該取付用金具８を止めねじにより分電盤の取付ベース１０１に固定するのが普通とするものである。しかし、これでは一次送りブレーカ３を交換する必要がある場合には、電源側の取付用金具８を取付ベース１０１に固定している止めねじを外す際に接続バー１４ａ、１４ｂが障害となるので、接続バー１４ａ、１４ｂを一次送り端子台１から外す必要がある。   Further, as shown in FIG. 14, the primary feed breaker 3 is configured such that the mounting bracket 8 is engaged with concave locking portions 31a, 31a provided below the power source side and the load side of the case 31, and the mounting bracket 8 is engaged. It is usual to fix 8 to the mounting base 101 of a distribution board with a set screw. However, when the primary feed breaker 3 needs to be replaced, the connection bars 14a and 14b become obstacles when removing the set screw that fixes the power supply side mounting bracket 8 to the mounting base 101. It is necessary to remove the connection bars 14a and 14b from the primary feed terminal block 1.

そこで、図１５―図１７に示す実施例の４においては、送り端子台１の他方側の下方に係止用脚板部１６を延設して、該係止用脚板部１６の先端に形成した突起部を一次送りブレーカ３のケース３１の電源側の側面下方に設けた凹状の係止部３１ａを係合させて、該一次送りブレーカ３を分電盤の取付ベース１０１に固定するものとしている。なお、係止用脚板部１６の先端を凹状に形成して、一次送りブレーカ３のケース３１の電源側の側面下方に凸状の係止部３１ａを形成して係合するものとしてもよい。   Therefore, in the fourth embodiment shown in FIGS. 15 to 17, the locking leg plate portion 16 is extended below the other side of the feed terminal block 1 and formed at the tip of the locking leg plate portion 16. The primary feed breaker 3 is fixed to the mounting base 101 of the distribution board by engaging the concave engaging portion 31a provided on the lower side of the power supply side of the case 31 of the primary feed breaker 3 with the protrusion. . The front end of the locking leg plate portion 16 may be formed in a concave shape, and a protruding locking portion 31a may be formed and engaged below the side surface on the power source side of the case 31 of the primary feed breaker 3.

これは、一次送りブレーカ３を交換する際に、一次送りブレーカ３への接続バーのねじ止めを外した後に、該一次送りブレーカ３の負荷側の下方に取り付けた取付用金具８による分電盤の取付ベース１０１に対する固定を解けば、一次送りブレーカ３を負荷側にスライドすることにより係止部３１ａが係止用脚板部１６の先端との係止を解除するとともに接続バー１４ａ、１４ｂも一次送りブレーカ３から離脱するので送り端子台１から接続バー１４ａ、１４ｂを外すことなく分電盤から取り外すことができる。そして、交換する新たな一次送りブレーカは前記と逆の手順により取り付けできるものである。   This is because when the primary feed breaker 3 is replaced, the distribution board by the mounting bracket 8 attached to the lower side of the load side of the primary feed breaker 3 after unscrewing the connecting bar to the primary feed breaker 3 is removed. If the fixing to the mounting base 101 is released, by sliding the primary feed breaker 3 to the load side, the locking part 31a releases the locking with the tip of the locking leg plate part 16 and the connection bars 14a, 14b are also primary. Since it is detached from the feed breaker 3, it can be removed from the distribution board without removing the connection bars 14a, 14b from the feed terminal block 1. The new primary feed breaker to be replaced can be attached by the reverse procedure.

また、図１８に示すように、一次送り端子台１には、端子ネジ１３をもって、２本の電圧線２ａ、２ｂと１本の中性線２ｃを接続するとともに、主幹ブレーカ４に接続される３本の中継用電線５ａ、５ｂ、５ｃが接続されており、各極において２本の線が接続されている。この際、下側になった線（図示のものをは電圧線２ａ）の先端に取り付けられた圧着端子１８が下に曲がり、取付ベース１０１に接しないよう、一次送り端子台１の一方の側の各極の側面に、圧着端子１８が下に曲がるのを規制する曲がり防止リブを設けることが好ましい。   As shown in FIG. 18, the primary feed terminal block 1 is connected to the main breaker 4 while connecting the two voltage lines 2 a and 2 b and the one neutral line 2 c with the terminal screw 13. Three relay wires 5a, 5b, and 5c are connected, and two wires are connected at each pole. At this time, one side of the primary feed terminal block 1 is attached so that the crimp terminal 18 attached to the tip of the lower wire (the voltage wire 2a in the drawing) is bent downward and does not contact the attachment base 101. It is preferable to provide a bending prevention rib for restricting the crimp terminal 18 from bending downward on the side surface of each of the electrodes.
