【０００１】
【発明の属する技術分野】
本発明は、基台にパネルを載置し、パネル上にブレーカ等の電気機器を配置して成る住宅用分電盤のパネルの取り付け構造に関する。
【０００２】
【従来の技術】
従来の分電盤は、ブレーカ２１を載置するパネル２２の一部を切り起こして掛止部を設け、掛止部にブレーカ２１を掛止させて取り付け位置を決め、図４に示すように、ブレーカ２１の左右端部でねじ止めをし固定していた（例えば特許文献１参照。）。
【０００３】
【特許文献１】
特開２００１−３２７００９号公報
【０００４】
【発明が解決しようとする課題】
しかしながら上記従来技術における分電盤では、ブレーカ２１をねじ止めするためのスペースが必要となり、パネル２２が大きくなっていた。ねじ止めは左右端部で行うため、中央部分の強度が低かった。その他、銅バーが直近にある場合には、パネルに掛止部を設けてブレーカを固定することはできなかった。
【０００５】
【課題を解決するための手段】
そこで本発明は、部品点数を抑え安価に組み立て可能である住宅用分電盤を提供することを目的とし、その構造は、基台の底面には、ブレーカの取り付け位置に対向させた係止部を突設し、係止部には食い切り穴とブレーカに設けられた突出部に対向する取り付け穴とを設けると共に、パネルには食い切り穴に差し込み可能な差し込み部と、取り付け穴に対向する係止穴とを設け、パネルの差し込み部を基台の食い切り穴に差し込み、ブレーカの突出部を取り付け穴と係止穴とに係止させて、ブレーカを固定可能としたことを特徴とする。
【０００６】
【発明の実施の形態】
住宅用分電盤は、基台にパネルを敷き、パネルにブレーカ等の電気機器を配置する。基台にはパネルとブレーカとを共に係止する係止部を突設し、係止部には食い切り穴と取り付け穴とをそれぞれ設ける。パネルには食い切り穴に対向する位置に差し込み部を、取り付け穴に対向する位置に係止穴を設ける。パネルを食い切り穴に差し込み部を差し込み、取り付け穴に係止穴を対向させて基台に載置し、その状態で、ブレーカの突出部を係止穴と取り付け穴とに係止させて、ブレーカを基台に固定すると同時にパネルも基台に固定する。
【０００７】
【実施例】
本発明に係る住宅用分電盤のパネル取り付け構造の実施例を図１〜図２の添付図面に基づいて説明する。
【０００８】
住宅用分電盤は、底面と該底面の四辺に側面を設け、前面に開口を有する箱状の基台１にパネル２を載置し、パネル２上にブレーカ３等の電気機器を配置して構成される。本発明はパネル２の取り付け構造に関する。
【０００９】
基台１には、底面に住宅用分電盤内側に向けて係止部４を突設し、係止部４には食い切り穴５と取り付け穴６とをそれぞれ設ける。
【００１０】
パネル２には、基台１に設けた食い切り穴５に差し込み可能である差し込み部７を形成すると共に、取り付け穴６に対向する位置には係止穴８を設ける。
【００１１】
ブレーカには、端部側面に基台１に固定するための突出部９を形成する。
【００１２】
パネル２の差し込み部７を食い切り穴５に差し込んでパネル取り付けの位置決めをしながら、取り付け穴６に係止穴８を対向させて基台１にパネル２を載置する。その上からブレーカ３を取り付けるが、ブレーカ３の突出部９をパネル２に設けた係止穴８と基台１に設けた取り付け穴６に係止させる。ブレーカ３を基台１に固定すると同時に、パネル２も基台１に固定する。
【００１３】
本発明の住宅用分電盤のパネル取り付け構造に使用するパネルは、配置するブレーカの個数は問わず、複数個載置可能としても、１個のみ載置できるものでもよい。
【００１４】
また、基台に設けるパネル固定用の係止部は食い切り穴に限定されるものではなく、袋状の形状に変更してもよく、本発明の趣旨を逸脱しない範囲において適宜変更可能である。
【００１５】
【発明の効果】
以上述べたように、本発明は、基台の底面には、ブレーカの取り付け位置に対向させた係止部を突設し、係止部には食い切り穴とブレーカに設けられた突出部に対向する取り付け穴とを設けると共に、パネルには食い切り穴に差し込み可能な差し込み部と、取り付け穴に対向する係止穴とを設け、パネルの差し込み部を基台の食い切り穴に差し込み、ブレーカの突出部を取り付け穴と係止穴とに係止させて、ブレーカを固定可能としたため、ねじ等の他の部品も必要なく、ブレーカとパネルの基台への取り付けが同時に行えるため作業性が向上する。ブレーカの取り付けは差し込むだけでよいため、位置決めも容易である。パネルやブレーカは１個ずつ基台に固定されるため、分岐中央部の強度も増すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a panel mounting structure for a residential distribution board in which a panel is placed on a base and electric devices such as breakers are arranged on the panel.
[0002]
[Prior art]
In the conventional distribution board, a part of the panel 22 on which the breaker 21 is placed is cut and raised to provide a latching portion, and the breaker 21 is latched on the latching portion to determine the mounting position. The left and right ends of the breaker 21 are fixed with screws (for example, see Patent Document 1).
[0003]
[Patent Document 1]
[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-327209
[Problems to be solved by the invention]
However, in the distribution board in the above-described prior art, a space for screwing the breaker 21 is required, and the panel 22 is large. Since screwing is performed at the left and right ends, the strength of the central portion was low. In addition, when the copper bar was closest, it was not possible to fix the breaker by providing a latching portion on the panel.
[0005]
[Means for Solving the Problems]
Therefore, the present invention has an object to provide a residential distribution board that can be assembled at a low cost with a reduced number of parts, and its structure is a locking portion that is opposed to a breaker mounting position on the bottom surface of the base. The locking part is provided with a countersunk hole and a mounting hole facing the protruding part provided in the breaker, and the panel has an insertion part that can be inserted into the countersink hole and a locking part that opposes the mounting hole. The breaker can be fixed by providing a hole, inserting the insertion portion of the panel into the cut-out hole of the base, and locking the protruding portion of the breaker to the mounting hole and the locking hole.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
A residential distribution board has a panel on the base and electrical devices such as breakers on the panel. The base is provided with a locking portion for locking the panel and the breaker together, and a cut-off hole and a mounting hole are provided in the locking portion. The panel is provided with an insertion portion at a position facing the cutout hole and a locking hole at a position facing the mounting hole. Insert the panel into the cut-out hole, place the mounting hole on the base with the locking hole facing the mounting hole, and in this state, lock the breaker's protrusion into the locking hole and the mounting hole. At the same time, fix the panel to the base.
[0007]
【Example】
An embodiment of a panel mounting structure for a residential distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0008]
A residential distribution board is provided with a panel 2 mounted on a box-shaped base 1 having a bottom surface and four sides on the bottom surface, and an opening on the front surface. Configured. The present invention relates to a panel 2 mounting structure.
[0009]
The base 1 is provided with a locking portion 4 protruding from the bottom toward the inside of the residential distribution board, and the locking portion 4 is provided with a countersink hole 5 and a mounting hole 6.
[0010]
The panel 2 is formed with an insertion portion 7 that can be inserted into the cut-out hole 5 provided in the base 1, and a locking hole 8 is provided at a position facing the attachment hole 6.
[0011]
The breaker is formed with a protruding portion 9 for fixing to the base 1 on the side surface of the end portion.
[0012]
The panel 2 is placed on the base 1 while the insertion portion 7 of the panel 2 is inserted into the cut-out hole 5 and positioning of the panel attachment is performed, with the locking hole 8 facing the attachment hole 6. The breaker 3 is attached from above, and the protruding portion 9 of the breaker 3 is engaged with the engagement hole 8 provided in the panel 2 and the attachment hole 6 provided in the base 1. At the same time that the breaker 3 is fixed to the base 1, the panel 2 is also fixed to the base 1.
[0013]
The panel used for the panel mounting structure of the residential distribution board of the present invention is not limited to the number of breakers to be arranged, and a plurality of panels may be placed or only one may be placed.
[0014]
Further, the locking portion for fixing the panel provided on the base is not limited to the counterbore, but may be changed to a bag shape, and can be changed as appropriate without departing from the gist of the present invention.
[0015]
【The invention's effect】
As described above, according to the present invention, a locking portion is provided on the bottom surface of the base so as to face the mounting position of the breaker , and the locking portion faces the biting hole and the protruding portion provided on the breaker. The panel is provided with an insertion part that can be inserted into the cut-off hole and a locking hole that faces the attachment hole. The insertion part of the panel is inserted into the cut-out hole of the base, and the protruding part of the breaker Since the breaker can be fixed by being locked in the mounting hole and the locking hole, other parts such as screws are not necessary, and the breaker and the panel can be attached to the base at the same time, thereby improving workability. Since it is only necessary to insert the breaker, positioning is easy. Since the panels and breakers are fixed to the base one by one, the strength of the center of the branch can be increased.
