Description

【０００１】
【産業上の利用分野】
本発明は、分電盤用ボックスの内部に配設される電気機器や配線を被覆するための配線被覆板の取り付け構造に関する。
【０００２】
【従来の技術】
従来、図５に示すように分電盤用ボックス３１は、箱体本体３２の前面に開口部３３が設けられ、開口部３３の全周に亘って略Ｌ字状に段部３２ａが折曲形成されている。箱体本体３２の背面板３２ｂには略平板状の機器取り付けパネル３４が取り付けられ、機器取り付けパネル３４には主幹ブレーカ（図示せず）や分岐ブレーカ（図示せず）等の電気機器（図示せず）が配設され、電気機器には配線（図示せず）が施されている。また、機器取り付けパネル３４の四隅近傍には配線被覆板用支柱３５，３５，３５，３５が立設され、開口部３３から挿入できるように開口部３３より小さい寸法に形成した配線被覆板３６を配線被覆板用支柱３５，３５，３５，３５に取り付けて電気機器や配線を被覆していた。
【０００３】
【発明が解決しようとする課題】
上記従来の分電盤用ボックスは、配線被覆板３６を開口部３３より小さい寸法に形成しているために配線被覆板３６と箱体本体３２の段部３２ａとの間に間隙３７ができ、箱体本体３２を前面側から見た際に間隙３７から電気機器への配線等が見えてしまうため、体裁が悪いという欠点があった。また、電気機器に配線する際に配線被覆板用支柱３５，３５，３５，３５が邪魔になるという欠点があった。
【０００４】
【課題を解決するための手段】
上記従来の分電盤用ボックスの問題点に鑑み、本発明の目的は、電気機器への配線がしやすく、箱体本体の外側から箱体本体内部の配線が見えないようにした体裁の良好な分電盤用ボックスを提供するもので、その構造は、少なくとも箱体本体の前面に開口部を設け、開口部の全周に亘り端縁を内側方向に折曲した後、前面方向に折曲して断面略Ｌ字状に段部を折曲形成した分電盤用ボックスにおいて、箱体本体内側の全周に亘って段部に連設して配線被覆板取付面を有する断面略Ｌ字状の取り付け板を配線被覆板取付面が開口部より内側に張出するように設け、取り付け板の配線被覆板取付面に配線被覆板を取り付けたことである。
【０００５】
【発明の実施の形態】
請求項１に記載の分電盤用ボックスによれば、少なくとも箱体本体の前面に開口部を設け、開口部の全周に亘り端縁を内側方向に折曲した後、前面方向に折曲して断面略Ｌ字状に段部を折曲形成した分電盤用ボックスにおいて、箱体本体内側の全周に亘って段部に連設して配線被覆板取付面を有する断面略Ｌ字状の取り付け板を配線被覆板取付面が開口部より内側に張出するように設け、取り付け板の配線被覆板取付面に配線被覆板を取り付けたことにより、電気機器への配線がしやすく、箱体本体の外側から箱体本体内部の配線が見えなくなり、外観が向上する。
【０００６】
【実施例】
本発明に係る分電盤用ボックスの構造の第一実施例を図１及び図２の添付図面に基づいて説明する。
【０００７】
分電盤用ボックス１は、箱体本体２の前面に開口部３が設けられ、開口部３の全周に亘って端縁を内側方向に折曲した後、前面方向に折曲して断面略Ｌ字状に段部２ａが折曲形成されている。箱体本体２内側の側面板２ｂの前面側近傍の全周には、開口部３の内側方向に向けて配線被覆板取付面を有する断面略Ｌ字状の取り付け板４が配線被覆板取付面が開口部より内側に張出するように溶接等により固定されている。取り付け板４は側面板２ｂから開口部３までの段部２ａの幅寸法５よりも長い寸法に形成され、箱体本体２の前面側から見ると、取り付け板４が段部２ａよりも突出している。
【０００８】
箱体本体２の背面板２ｃには、略平板状の機器取り付けパネル６が取り付けられ、機器取り付けパネル６には主幹ブレーカ（図示せず）や分岐ブレーカ（図示せず）等の電気機器（図示せず）が配設され、電気機器には配線（図示せず）が施されている。
【０００９】
箱体本体２には、開口部３より僅かに小さい寸法に形成した配線被覆板７が設けられる。そのため、配線被覆板７の四隅近傍には螺子挿通孔８，８，８，８が穿設され、螺子挿通孔８，８，８，８と対向する箱体本体２の取り付け板４には螺子孔９，９，９，９が穿設されている。配線被覆板７は螺子挿通孔８，８，８，８と取り付け板４の螺子孔９，９，９，９に螺子１０，１０，１０，１０を挿通させて螺着固定される。
【００１０】
箱体本体２の内部は配線被覆板７と取り付け板４とにより完全に被覆されるため、箱体本体２の外側から箱体本体２の内部の配線は見えなくなる。また、箱体本体２内側の側面板２ｂの全周には、取り付け板４が溶接等により固定されるため、箱体本体２の強度が増す。また、従来の分電盤用ボックスに設けられていた配線被覆板用支柱がないために電気機器への配線をスムーズに行うことができる。
【００１１】
尚、本実施例において、配線被覆板を箱体本体の取り付け板に螺着固定したが、固定手段に限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００１２】
また、本実施例において、取り付け板の形状に限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００１３】
本発明に係る分電盤用ボックスの構造の第二実施例を図３及び図４の添付図面に基づいて説明する。
【００１４】
分電盤用ボックス２１は、箱体本体２２の前面に開口部２３が設けられ、開口部２３の全周に亘って端縁を内側方向に折曲した後、前面方向に折曲して断面略Ｌ字状に段部２２ａが折曲形成されている。また、段部２２ａの先端部２２ｂはヘミング曲げされて更に開口部２３の内側方向に向けて折曲されて取り付け部２２ｃが形成されている。
【００１５】
箱体本体２２の背面板２２ｄには、略平板状の機器取り付けパネル２４が取り付けられ、機器取り付けパネル２４には主幹ブレーカ（図示せず）や分岐ブレーカ（図示せず）等の電気機器が配設され、電気機器には配線（図示せず）が施されている。
【００１６】
箱体本体２２には、開口部２３より僅かに小さい寸法に形成した配線被覆板２５が設けられる。そのため、配線被覆板２５の四隅近傍には螺子挿通孔２６，２６，２６，２６が穿設され、螺子挿通孔２６，２６，２６，２６と対向する箱体本体２２の取り付け部２２ｃには螺子孔２７，２７，２７，２７が穿設されている。配線被覆板２５は螺子挿通孔２６，２６，２６，２６と取り付け部２２ｃの螺子孔２７，２７，２７，２７に螺子２８，２８，２８，２８を挿通させて螺着固定される。
【００１７】
箱体本体２２の内部は配線被覆板２５と取り付け部２２ｃとにより完全に被覆されるため、箱体本体２２の外側から箱体本体２２の内部の配線は見えなくなる。また、従来の分電盤用ボックスに設けられていた配線被覆板用支柱がないために電気機器への配線をスムーズに行うことができる。
【００１８】
尚、本実施例において、配線被覆板と取り付け板とを螺着固定したが固定手段に限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００１９】
また、本実施例において、段部及び取り付け部の形状に限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００２０】
【発明の効果】
以上のように本発明に係る分電盤用ボックスは、少なくとも箱体本体の前面に開口部を設け、開口部の全周に亘り端縁を内側方向に折曲した後、前面方向に折曲して断面略Ｌ字状に段部を折曲形成した分電盤用ボックスにおいて、箱体本体内側の全周に亘って段部に連設して配線被覆板取付面を有する断面略Ｌ字状の取り付け板を配線被覆板取付面が開口部より内側に張出するように設け、取り付け板の配線被覆板取付面に配線被覆板を取り付けたことにより、従来の分電盤用ボックスに設けられる配線被覆板用支柱が無いために電気機器への配線がしやすく、箱体本体の外側から箱体本体内部の配線が見えなくなるために外観が向上するという優れた効果がある。
