Description

【０００１】
【発明の属する技術分野】
本発明は、分電盤において箱体に基板を取付けるための技術に関するものである。
【０００２】
【従来の技術】
既設の分電盤において、分電盤の外殻を形成する箱体に主幹開閉器や分岐開閉器等の電気機器を取着した基板を取付けてあるが、この場合、箱体の背板部の略四隅位置にボルトが突設してあって、該ボルトに基板の四隅部に設けた孔を通し、ナットにより取付けてあった。ところが、従来にあっては、基板のサイズが一定でなく、種々のサイズがあり、これに応じて箱体の四隅に突設するボルトの突設位置が決定してあった。このため、既存の分電盤においては、ボルトの突設位置が種々異なっていた。
【０００３】
一方、現在は基板のサイズが標準化されている。そして、既存の分電盤において箱体を残したまま、基板を新たに取り替えようとした場合、既存の箱体に固着しているボルトは前述のように、突出位置が種々異なっているので、現在の標準化された基板を既存のボルトに取付けることができないという問題があった。そこで、強いて既存の箱のみ残して新たに基板を取り換えようとする場合、既存の箱のボルトの突設位置に取付けることができるようなサイズの新たな基板を特別に形成する必要があり、現在標準化されている基板を使用できないという問題があった。
【０００４】
【発明が解決しようとする課題】
本発明は上記の従来例の問題点に鑑みて発明したものであって、箱体に突設したボルトの位置の違いにかかわらず標準化されたサイズの基板を簡単且つ確実に取付けることができる分電盤を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、本発明の分電盤は、背板部１の略四隅位置において各々前方に突出するボルト２を固着した前面開口の箱体３と、この箱体３内に配設され、主幹開閉器４や分岐開閉器５等の電気機器を取着した基板６と、該基板６の上部両端部及び下部両端部に架設され且つ両側にそれぞれ横長孔１５を有する架設部材１２と、架設部材１２の横長孔１５に貫通する基板固定ボルト７の挿通部８及び箱体３から突設したボルト２が貫通する貫通孔９を各々有し、該挿通部８及び貫通孔９の一方を長孔状に形成して各基板固定ボルト７及びボルト２に各々ナットを取着することにより基板６を箱体３に固定する４つの基板取着調整部材１１と、を備えて成ることを特徴とするものであってもよい。このような構成とすることで、箱体３に設けたボルト２に基板取着調整部材１１、架設部材１２を介して基板６を取付けることができるものであり、また、ボルト２又は基板固定ボルト７の基板取着調整部材１１に設けた長孔に貫通する位置を調整することで、箱体３における基板６の取付け位置を調整することができるものであり、また、架設部材１２の横長孔１５に沿って基板固定ボルト７の位置調整をすることで、箱体３内における基板６の水平方向の位置調整が簡単にできることになる。
【０００７】
また、基板取着調整部材１１が、貫通孔９を有する本体片部１１ａの端部から前方に前向き突片部１３を折曲突設すると共に該前向き突片部１３の先端部から本体片部１１ａの突出方向と略同じ方向に向けて前横片部１４を折曲突設して構成され、前横片部１４に挿通部８を形成することが好ましい。このような構成とすることで、箱体３に突設してあるボルト２と基板６との位置が近接する場合であっても、簡単に取着することができるものである。
【０００８】
【発明の実施の形態】
本発明は以下添付図面に示す実施形態に基づいて説明する。
まず、図１乃至図４には本発明の一実施形態が示してある。図１には本発明の一実施形態の分解斜視図が示してあり、この実施形態においては、既設の分電盤の箱体３を残し、この箱体３から既設の基板を外し、これに代えて新たに標準化された新しい基板６を取付ける場合の例が示してある。
【０００９】
既設の箱体３は前面が開口しており、箱体３の内部において背板部１の略四隅位置からぞれぞれ既設のボルト２が固着してあって、各ボルト２は前方に向けて突出している。このボルト２は、既設の基板を取付けるために既設の箱体３に固着してあったボルトである。
新たに取付ける新設の基板６は主幹開閉器４や分岐開閉器５等の電気機器を取着したもので、該基板６の上部両端部と、下部両端部とにはそれぞれ孔１６が設けてある。そして、この新たに取付ける基板６はサイズが規格化されており、したがって上記基板６の四隅に設けた孔１６の位置も規格化された一定の位置となっている。
【００１０】
図中１１は基板取着調整部材であって、図５に示す実施形態においては、短冊状をした本体片部１１ａの端部から前方に前向き突片部１３を突設し、該前向き突片部１３の前端部から本体片部１１ａと反対方向に前横片部１４を突設してある。ここで、本体片部１１ａに上記箱体３の背板部１に突設したボルト２が挿通される貫通孔９が形成してあり、前横片部１４に基板固定ボルト７を挿通するための挿通部８が設けてあり、上記貫通孔９、挿通部８のうち、本体片部１１ａに設けた貫通孔９が短冊状の本体片部１１ａの長手方向と平行な方向に長くなった長孔状となっている。
【００１１】
しかして、既設の箱体３のボルト２に新たに新設の基板６を取付けるにあたっては、既設の箱体３の内部の略四隅付近に設けた各ボルト２にそれぞれ基板取着調整部材１１を仮取付けしておく。つまり、基板取着調整部材１１に設けた貫通孔９をボルト２に通し、ボルト２にナット１７を緩く締め付けておく。そして、このようにして取付けた４つの基板取着調整部材１１の各挿通部８と、基板６の上部両端部及び下部両端部に設けた孔１６とを合わせて基板固定ボルト７を上記挿通部８と孔１６とに貫挿させて、該基板固定ボルト７にナット１８を螺合するものである（図３、図４参照）。
【００１２】
上記説明ではボルト２に先に基板取着調整部材１１を取付け、その後に、基板取着調整部材１１に基板６を取付けた例を示したが、基板６の四隅に設け孔１６にそれぞれ基板取着調整部材１１の挿通部８を合わせて基板固定ボルト７を貫挿し、ナット１８を緩く締め付けておき、その後、基板６の四隅に取付けた各基板取着調整部材１１の貫通孔９をそれぞれ箱体３の背板部１の略四隅に突設した各ボルト２に通し、ナット１７を螺合して取付けるようにしてもよい。
【００１３】
なお、上記いずれの場合においても、ナット１７、ナット１８の本締めの前に、貫通孔９又は挿通部８の長孔状となった部分を利用してボルト２や基板固定ボルト７を長孔に沿ってスライドさせることにより基板６の位置調整を行い、位置調整後にナット１７、ナット１８を本締するものである。
図３には既存の４本のボルト２に４つの基板取着調整部材１１を介して新規の基板６を取付けた状態の正面図が示してある。
【００１４】
図中１９は中蓋であって、箱体３に対して着脱自在に取付けられるものである。また、箱体３には図２に示すように扉２０を開閉自在に取付けた扉枠２１が取付けられるものである。
次に、図６乃至図８に基づいて本発明の他の実施形態につき説明する。本実施形態においては、既設の箱体１の背板部１の略四隅位置からぞれぞれ既設のボルト２が前方に突設してある点、図４に示すような基板取着調整部材１１を４つ使用する点、サイズが規格化された新たに取付ける基板６の四隅の一定の位置に孔１６が設けてある点は前述の実施形態と同様であるので、同じ構成についての説明は重複するので省略し、前述の実施形態と異なる点についてのみ説明する。
【００１５】
すなわち、新たに取付けるサイズが規格化された基板６の四隅に設けた孔１６の位置は前述のように規格化された一定の位置であるが、この基板６の四隅に設けた孔１６を利用して図８に示すような架設部材１２を基板６の上部の両端部間及び下部の両端部間に架設する。架設部材１２は断面Ｌ状をした長尺の本体部２２の両側の前端部にそれぞれ後片２３と平行な前固定片２４を設けて構成してあり、後片２３の両側部にはそれぞれ長尺の本体部２２の長手方向に平行な方向に長くなった横長孔１５が形成してある。また、前固定片２４には挿通部２５が設けてある。
【００１６】
そして、基板６の上部の両端部に設けた孔１６に架設部材１２の両端部の前端部に設けた挿通部２５を合わせてボルト２７を挿通してナット３０により固定し、また、同様にして基板６の下部の両端部に設けた孔１６に別の架設部材１２の両端部の前端部に設けた挿通部２５を合わせてボルト２７を挿通してナット３０により固定することで、基板６の上部及び下部にそれぞれ架設部材１２を架設するものである。
【００１７】
一方、既設の箱体３の内部の略四隅付近に設けた各ボルト２にそれぞれ基板取着調整部材１１を仮取付けし、このようにして取付けた４つの基板取着調整部材１１の各挿通部８と、基板６の上部及び下部に架設した架設部材１２に設けた横長孔１５とに基板固定ボルト７を挿通して、該基板固定ボルト７にナット１８を螺合するものである。
【００１８】
上記説明では、基板６の上部及び下部に架設部材１２を先に取付け、また、箱体３に突設した４つのボルト２に先に基板取着調整部材１１を取付け、その後、基板６に取付けた架設部材１２に４つのボルト２に先に取付けた基板取着調整部材１１を取付ける例につき説明したがこれにのみ限定されるものではない。すなわち、基板６の上部及び下部に架設部材１２を先に取付け、更に、この基板６の上下部に取付けた架設部材１２の両側の横長孔１５にそれぞれ基板取着調整部材１１に形成した挿通部８を基板固定ボルト７、ナット１８で仮取付けし、その後、このようにして取付けた４つの基板取着調整部材１１の各貫通孔９を箱体３の内部の略四隅付近に設けた各ボルト２に通してナット１７を螺合することで取付けるようにしたり、あるいは、既設の箱体３の内部の略四隅付近に設けた各ボルト２にそれぞれ基板取着調整部材１１の貫通孔９を通してナット１７で仮取付けし、上部の両側に位置する基板取着調整部材１１の挿通部８と上部の架設部材１２の両側の横長孔１５とを合わせて基板固定ボルト７、ナット１８で仮取付けし、同様にして下部の両側に位置する基板取着調整部材１１の挿通部８と下部の架設部材１２の両側の横長孔１５とを合わせて基板固定ボルト７、ナット１８で仮取付けし、その後、新設の基板６の上部両側に設けた孔１６と上の架設部材１２の両端部の挿通部２５とを合わせてボルト２７を貫挿してナット３０により取付けると共に基板６の下部両側に設けた孔１６と下の架設部材１２の両端部の挿通部２５とを合わせてボルト２７を貫挿してナット３０により取付けものである。
【００１９】
なお、上記いずれの場合においても、ナット１７、ナット１８の本締めの前に、貫通孔９又は挿通部８の長孔状となった部分や横長孔１５を利用してボルト２や基板固定ボルト７をスライドさせることにより基板６の位置調整を行い、位置調整後にナット１７、ナット１８を本締するものである。
そして、本実施形態においては、架設部材１２が水平となるように取付けることで、基板６を水平に取付けることができ、また、このように架設部材１２を水平に取付けた状態で、横長孔１５に沿ってスライドさせることで、基板６を箱体１内の横方向の任意の位置に配設することができ、例えば箱体１内の横方向の中心に基板６の中心が位置するように配置することが可能となる。
【００２０】
図９には本発明に用いる基板取着調整部材１１の他の実施形態が示してある。この実施形態においては、基板取着調整部材１１は、貫通孔９を有する本体片部１１ａの端部から前方に前向き突片部１３を折曲突設し、該前向き突片部１３の先端部から本体片部１１ａの突出方向と略同じ方向に向けて挿通部８を有する前横片部１４を折曲突設して構成してある。このような構成とすることで、前述のいずれの実施形態においてもボルト２の位置と、基板６の挿通部８との取付け位置とが近接するような場合であっても容易に基板６を取付けることができるものである。
【００２１】
なお、上記した各実施形態においては、既設の箱体１から既設の基板６を外して新しい基板６を取付ける例につき説明したが、これのみに限定されるものではなく、新規の箱体１の内部の背板部１の四隅部分に突設するボルト７に新規の基板６を取付ける際に、上記基板取着調整部材１１を介して取付けたり、あるいは、基板取着調整部材１１と架設部材１２とを介して取付けたりするようにしてもよいのは勿論である。
【００２３】

【００２４】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、基板取着調整部材が、貫通孔を有する本体片部の端部から前方に前向き突片部を折曲突設すると共に該前向き突片部の先端部から本体片部の突出方向と略同じ方向に向けて前横片部を折曲突設して構成され、前横片部に挿通部を形成してあるので、箱体に突設してあるボルトと基板との位置が近接する場合であっても、簡単に取着することができるものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for attaching a substrate to a box in a distribution board.
[0002]
[Prior art]
In the existing distribution board, a board on which electrical equipment such as a main switch and a branch switch is attached to a box forming the outer shell of the distribution board. Bolts protruded at approximately four corners of the board, and the bolts were passed through holes provided at the four corners of the substrate, and attached with nuts. However, in the related art, the size of the substrate is not constant, and there are various sizes, and the protruding positions of the bolts protruding from the four corners of the box are determined according to the size. For this reason, in the existing distribution board, the projecting positions of the bolts are variously different.
[0003]
On the other hand, at present, the size of the substrate is standardized. Then, when the board is to be replaced anew with the box body left in the existing distribution board, the bolts fixed to the existing box body have different projection positions as described above, There is a problem that the current standardized board cannot be attached to the existing bolt. Therefore, when trying to replace a new board while leaving only the existing box, it is necessary to specially form a new board of a size that can be attached to the projecting position of the bolt of the existing box. There is a problem that a standardized substrate cannot be used.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the related art, and can easily and surely mount a substrate having a standardized size regardless of the position of a bolt protruding from a box. It is an object to provide a power board.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the distribution board of the present invention is provided with a box body 3 having a front opening to which bolts 2 protruding forward are fixed at substantially four corner positions of a back plate 1, and arranged inside the box body 3. A board 6 on which electric devices such as the main switch 4 and the branch switch 5 are mounted, and an erecting member 12 which is installed at both upper and lower ends of the substrate 6 and has horizontally long holes 15 on both sides. And a through hole 9 through which the board fixing bolt 7 penetrates the horizontally long hole 15 of the erection member 12 and a through hole 9 through which the bolt 2 protruding from the box body 3 penetrates. Four substrate attachment adjusting members 11 for fixing one of the substrates 6 to the box body 3 by forming one of the holes into a long hole shape and attaching nuts to the substrate fixing bolts 7 and the bolts 2 respectively. May be characterized. With such a configuration, the board 6 can be attached to the bolt 2 provided on the box 3 via the board attachment adjusting member 11 and the bridging member 12. By adjusting the position penetrating the elongated hole provided in the substrate attachment adjusting member 11 of FIG. 7, the mounting position of the substrate 6 in the box body 3 can be adjusted. By adjusting the position of the board fixing bolt 7 along 15, the horizontal position of the board 6 in the box 3 can be easily adjusted.
[0007]
Further, the substrate attachment adjusting member 11 bends and protrudes a forward protruding piece 13 forward from an end of the main body piece 11 a having the through-hole 9. It is preferable that the front horizontal piece 14 be bent and protruded in substantially the same direction as the projecting direction of 11 a, and the insertion part 8 be formed in the front horizontal piece 14. With such a configuration, even when the positions of the bolts 2 projecting from the box body 3 and the substrate 6 are close to each other, the bolts 2 can be easily attached.
