Description

本発明は、幅薄型の分岐ブレーカを幅方向に複数並設して収納した分電盤に関する。   The present invention relates to a distribution board in which a plurality of thin branch breakers are arranged side by side in the width direction.

近年、電気機器の増加とともに分電盤の分岐回路数が増加している。分電盤は分岐回路を異常から保護するための分岐ブレーカが幅方向に必要数並設されており、分岐回路数が増加すると分岐ブレーカの設置スペースが拡大して分電盤が大型化するという問題がある。そこで、幅薄化された分岐ブレーカが開発され、分岐ブレーカの配置スペースを縮小して分電盤の小型化が図られている。分岐ブレーカは一般的にケース前面の長手方向に分岐回路をオン・オフするためにハンドル型の操作スイッチが設けられ、並設された分岐ブレーカは操作スイッチがケースの幅方向に一列になっている（特許文献１，特許文献２参照）。   In recent years, the number of branch circuits in the distribution board has increased with the increase in electrical equipment. The distribution board is equipped with the necessary number of branch breakers in the width direction to protect the branch circuit from abnormalities. As the number of branch circuits increases, the installation space for the branch breakers increases and the distribution board increases in size. There's a problem. Therefore, a branch breaker with a reduced width has been developed, and the distribution space of the branch breaker is reduced to reduce the size of the distribution board. The branch breaker is generally provided with a handle-type operation switch for turning on and off the branch circuit in the longitudinal direction of the front surface of the case, and in the branch breaker arranged in parallel, the operation switches are arranged in a row in the width direction of the case. (See Patent Document 1 and Patent Document 2).

特開２００２−３２４４７５号公報（図２）JP 2002-324475 A (FIG. 2) 特開２００２−２９１１１９号公報（図１）JP 2002-291119 A (FIG. 1)

薄型化された分岐ブレーカの幅寸法は具体的に１６ｍｍ程度であるが、更に分岐ブレーカを幅薄化した場合、操作スイッチの幅寸法が狭くなるとともに、隣り合う分岐ブレーカの操作スイッチ間の距離が狭くなるため、操作スイッチを操作する際に誤って隣の分岐ブレーカの操作スイッチを操作する虞があった。   The width of the thinned branch breaker is specifically about 16 mm. However, when the branch breaker is further thinned, the width of the operation switch becomes narrower and the distance between the operation switches of adjacent branch breakers becomes smaller. Therefore, when operating the operation switch, the operation switch of the adjacent branch breaker may be erroneously operated.

本発明は、ケース前面に電路をオン・オフするための操作スイッチが設けられ、ケース前面における幅方向の寸法を直交する長手方向の寸法より小さく形成した分岐ブレーカをケースの幅方向に複数並設した分電盤において、隣り合う分岐ブレーカの操作スイッチをケースの長手方向に交互にずらしてケースの幅方向に千鳥状となるようにしたことを特徴とする。 The present invention, the operation switch is provided for turning on and off an electrical path to the front of the case, a plurality of branch breakers smaller than the formed longitudinal dimension perpendicular to the width dimension of the case front to the width direction of the case parallel In the distribution board provided, the operation switches of adjacent branch breakers are alternately shifted in the longitudinal direction of the case so as to be staggered in the width direction of the case .

本発明によれば、分岐ブレーカの幅寸法が小さい場合において操作しようとする分岐ブレーカに隣接する分岐ブレーカの操作スイッチを誤って操作することがないようにするという効果がある。   According to the present invention, there is an effect that the operation switch of the branch breaker adjacent to the branch breaker to be operated is not erroneously operated when the width dimension of the branch breaker is small.

分電盤は主幹ブレーカの二次側に接続された導電バーに沿って分岐ブレーカをケースの幅方向に複数並設する。分岐ブレーカは操作スイッチをケースの長手方向にずらした２種類を用意し、分岐ブレーカの配置は隣り合う分岐ブレーカの操作スイッチがケースの長手方向に交互にずれてケースの幅方向に千鳥状となるようにする。 The distribution board has a plurality of branch breakers arranged in parallel in the width direction of the case along a conductive bar connected to the secondary side of the main breaker. Two types of branch breakers are prepared by shifting the operation switch in the longitudinal direction of the case. The arrangement of the branch breakers is staggered in the width direction of the case by alternately shifting the operation switches of adjacent branch breakers in the longitudinal direction of the case. Like that.

本発明に係る分電盤の実施例１を図１及び図２の添付図面に基づいて説明する。   First Embodiment A distribution board according to a first embodiment of the present invention will be described with reference to the accompanying drawings of FIGS.

分電盤１は、背面が壁面に取り付けられ前面が開口された本体２と、本体２の前面開口を施蓋するカバー３とで成っている。本体２は主幹ブレーカ４が取り付けられ、主幹ブレーカ４の二次側に３本の導電バー５，５，５が接続されて主幹ブレーカ４から離れるように右方向に延びている。この導電バー５を挟んで長手方向の両側には分岐ブレーカ６が対向して配置され、分岐ブレーカ６は導電バー５にケース６ａの一端面に設けられたプラグイン式の電源側端子６ｂを差し込み接続して導電バー５に沿って分岐ブレーカ６がケース６ａの幅方向に複数並設されている。   The distribution board 1 includes a main body 2 having a rear surface attached to a wall surface and an open front surface, and a cover 3 that covers the front opening of the main body 2. A main breaker 4 is attached to the main body 2, and three conductive bars 5, 5, 5 are connected to the secondary side of the main breaker 4, and extend to the right so as to be away from the main breaker 4. Branch breakers 6 are arranged opposite to each other in the longitudinal direction across the conductive bar 5, and the branch breaker 6 is inserted into the conductive bar 5 with a plug-in type power supply side terminal 6b provided on one end surface of the case 6a. A plurality of branch breakers 6 are connected along the conductive bar 5 in the width direction of the case 6a.

分岐ブレーカ６はケース６ａの前面に電路をオン・オフするためのハンドル型の操作スイッチ６ｃがケース６ａの長手方向に起倒可能に設けられ、操作スイッチ６ｃがケース６ａの長手方向にずらして設けられて２種類が用意されている。そして、分岐ブレーカ６の配置に際して隣り合う分岐ブレーカ６の操作スイッチ６ｃの位置がケース６ａの長手方向に交互にずれるようにケース６ａの幅方向に千鳥状になるようにされている。 The branch breaker 6 is provided with a handle-type operation switch 6c on the front surface of the case 6a that can be turned up and down in the longitudinal direction of the case 6a, and the operation switch 6c is shifted in the longitudinal direction of the case 6a. Two types are prepared. When the branch breakers 6 are arranged, the positions of the operation switches 6c of the adjacent branch breakers 6 are staggered in the width direction of the case 6a so as to be alternately shifted in the longitudinal direction of the case 6a .

このように取り付けられた分岐ブレーカ６は負荷側端子６ｄに接続される負荷名称を表示するための負荷名称表示板７が導電バー５の前面を覆うように充電部カバーの機能を兼ねて取り付けられている。それから、カバー３が主幹ブレーカ４と分岐ブレーカ６の操作スイッチ４ａ，６ｃを操作窓３ａ，３ｂから露出させるとともに、負荷名称表示板７を負荷名称窓３ｃから露出させて本体２に取り付けられる。   The branch breaker 6 attached in this way is attached with the function of the charging unit cover so that the load name display plate 7 for displaying the load name connected to the load side terminal 6d covers the front surface of the conductive bar 5. ing. Then, the cover 3 is attached to the main body 2 while exposing the operation switches 4a and 6c of the main breaker 4 and the branch breaker 6 from the operation windows 3a and 3b and exposing the load name display plate 7 from the load name window 3c.

尚、本実施例において、操作スイッチ６ｃの位置をケース６ａの長手方向にずらした２種類の分岐ブレーカ６を用いることによって分岐ブレーカ６の配列を一定にして隣り合う分岐ブレーカ６の操作スイッチ６ｃの位置をケース６ａの幅方向に千鳥状となるように配置したが、図３に示すように操作スイッチ１６ｃの位置が同じ１種類の分岐ブレーカ１６を用い、導電バー１５の長手方向端縁を分岐ブレーカ１６の幅寸法以上の間隔で凸凹状に形成して隣り合う分岐ブレーカ１６のケース１６ａの長手方向に分岐ブレーカ１６自体をずらすことにより隣り合う分岐ブレーカ１６の操作スイッチ１６ｃの位置をケース１６ａの幅方向に千鳥状となるように配置しても良い。   In this embodiment, by using two types of branch breakers 6 in which the position of the operation switch 6c is shifted in the longitudinal direction of the case 6a, the arrangement of the branch breakers 6 is fixed and the operation switches 6c of the adjacent branch breakers 6 are arranged. The positions are arranged in a staggered manner in the width direction of the case 6a. However, as shown in FIG. 3, one type of branch breaker 16 having the same position of the operation switch 16c is used, and the longitudinal edge of the conductive bar 15 is branched. By shifting the branch breaker 16 itself in the longitudinal direction of the case 16a of the adjacent branch breaker 16 formed in an uneven shape with an interval equal to or larger than the width dimension of the breaker 16, the position of the operation switch 16c of the adjacent branch breaker 16 is changed to the position of the case 16a. You may arrange | position so that it may become zigzag form in the width direction.

また、分岐ブレーカ６は導電バー５を挟んで両側に上下２列に配列しているが１列に配列しても良く、分岐ブレーカ６が配列される方向についても横方向ではなく縦方向であっても良い。また、操作スイッチ６ｃはハンドル型のものを用いているが、押しボタン型やシーソー型などでも良く、操作スイッチの形式及び形状について限定はなく、その他の形状及び構造についても本発明の趣旨を逸脱しない範囲において適宜に変更して実施することが可能である。   Further, the branch breakers 6 are arranged in two rows on both sides across the conductive bar 5, but may be arranged in one row, and the direction in which the branch breakers 6 are arranged is not a horizontal direction but a vertical direction. May be. The operation switch 6c is a handle type, but may be a push button type or a seesaw type, and the type and shape of the operation switch are not limited, and other shapes and structures also depart from the spirit of the present invention. It is possible to implement by changing appropriately within the range not to be.
