Description

本発明は、ブレーカ等の電気機器或いは情報端末機器を収納する分電盤のハウジングに関し、特に壁面に埋設して設置する形態と壁面から露出させて設置する形態の双方を可能とする分電盤ハウジングに関する。   The present invention relates to a power distribution board housing for housing electrical equipment or information terminal equipment such as a breaker, and more particularly to a power distribution board which can be installed in a form buried in a wall surface or in a form exposed from the wall surface. Regarding the housing.

ブレーカ等を収容する分電盤のハウジングには、ハウジングの主要部を壁面に埋設させて設置するものと、壁面に埋設せずに全体を壁面から露出させて設置するものとがある。そのため、この双方の設置形態に対応できるハウジングが提案されている。
例えば、特許文献１の分電盤ハウジングは、ハウジングの周囲に段部（段差）を設けて背部を一回り小さく形成し、この段差より後方を壁面に埋設可能とした。一方、埋設せずにハウジング全体を露出させる場合は、一回り小さいハウジング後部を覆って段差を無くすよう形成したカバー枠（被覆部材）をハウジング周囲に取り付けて対応した。 There are two types of housings of a distribution board that house a breaker or the like, in which the main part of the housing is buried in a wall surface and installed, and in which the main part of the housing is not buried in the wall surface but is exposed entirely from the wall surface. Therefore, a housing that can cope with both types of installation has been proposed.
For example, in the distribution board housing of Patent Document 1, a step (step) is provided around the housing to make the back one size smaller, and the rear of the step can be embedded in a wall surface. On the other hand, when exposing the entire housing without embedding, a cover frame (covering member) formed so as to cover a slightly smaller rear portion of the housing and eliminate the step is mounted around the housing.

特開平８−２０５３２５号公報JP-A-8-205325

上記カバー枠をハウジングに取り付ける構成は、露出設置した場合に段差部に塵が溜まり難いし、露出した埋設部が隠れるため外観的にも好ましかった。
しかしながら、ハウジングの周囲を覆うカバー枠は、一様な幅を有して隙間が発生しないよう形成されているため、ハウジング側面の埋設される部位に電線入出のため穴、或いは穴を形成可能なノックアウトが設けられている場合、この穴或いはノックアウトが使用できなくなった。
また、埋設部はハウジングの途中に段差を設けて形成されているため、この段差によりカバー枠の着脱はハウジングを壁面に取り付けた状態では難しかった。 The configuration in which the cover frame is attached to the housing is also preferable in appearance since dust is less likely to accumulate in the step portion when the cover frame is exposed and the exposed embedded portion is hidden.
However, since the cover frame that covers the periphery of the housing has a uniform width and is formed so as not to generate a gap, a hole or a hole can be formed in a buried portion of the side surface of the housing for inserting and removing electric wires. If a knockout was provided, this hole or knockout could not be used.
In addition, since the buried portion is formed by providing a step in the middle of the housing, it is difficult to attach or detach the cover frame when the housing is mounted on the wall surface due to the step.

そこで、本発明はこのような問題点に鑑み、埋設仕様のハウジング側面に設けられている電線入出部を、ハウジングを露出設置する場合でも使用することができ、またハウジングの埋設部を覆うカバー枠の着脱が容易な分電盤ハウジングを提供することを目的としている。   In view of such a problem, the present invention can use the wire entry / exit portion provided on the side surface of the housing of the embedded specification even when the housing is exposed and installed, and a cover frame that covers the embedded portion of the housing. It is an object of the present invention to provide a distribution board housing that allows easy attachment and detachment.

上記課題を解決する為に、請求項１の発明は、背板及び当該背板の周囲４辺を囲む側面板を有して、前面が開放されたハウジング本体と、ハウジング本体の前面を閉塞する前面板とを有し、内部に電気機器を収容可能とした分電盤ハウジングであって、側面板全体を覆うカバー枠を有する一方、側面板は少なくとも１側面板に電線を入出させるための穴を形成可能とするノックアウトが設けられており、カバー枠のノックアウトに対応する部位には、開口部の形成を容易とする薄肉部が形成されて成ることを特徴とする。

そして、カバー枠は前面板の外郭に一致する大きさを有するため、前面板を外すだけでカバー枠の着脱が可能であるし、ハウジング本体を露出して使用する場合はカバー枠を取り付けることで、前面板とハウジング本体との段差を無くしてすっきりした形状にでき、外観的に好ましい。 According to a second aspect of the present invention, in the configuration according to the first aspect, the front plate has a larger outer shell than the housing body and has a step between the two, and the cover frame has a size matching the outer shell of the front plate. The step is eliminated by the cover frame covering the side plate.
According to this configuration, since the front plate has a larger outer shell than the housing main body, if the cover frame is removed and the housing main body is embedded in the wall surface, the gap between the housing main body and the wall surface can be closed by the mounted front plate. No additional closing member is required.
And, since the cover frame has a size corresponding to the outline of the front plate, the cover frame can be attached and detached simply by removing the front plate, and when the housing body is exposed and used, the cover frame is attached. It is possible to eliminate the step between the front plate and the housing main body to form a simple shape, which is preferable in appearance.

請求項３の発明は、請求項１又は２に記載の構成において、カバー枠は前面板に連結される連結部を有し、前面板に連結された状態でハウジング本体の周囲に配置されて固定されることを特徴とする。
この構成によれば、カバー枠の取り付けは前面板に取り付ける操作のみで良く、簡易な操作で取り付けできる。 According to a third aspect of the present invention, in the configuration according to the first or second aspect, the cover frame has a connecting portion connected to the front plate, and is disposed around the housing body and fixed while being connected to the front plate. It is characterized by being performed.

図３は前面板３とカバー枠４の説明図であり、後方からみた分解斜視図である。図３に示すように、カバー枠４はハウジング本体２の側面板２２毎に分割され、４分割されて形成されている。そして、前面板３への連結部を有し、前面板３をハウジング本体２に取り付けることで、カバー枠４もハウジング本体２に装着されるよう構成されている。以下具体的に説明する。
前面板３は、周囲が後方に折り曲げられ、背部方向に一様な厚みを有するスカート部３１が形成されている。このスカート部３１は二重に形成されており、その間にカバー枠４を組み付けるためのスリット状の溝３３が形成され、且つ周設されている。 FIG. 3 is an explanatory view of the front plate 3 and the cover frame 4, and is an exploded perspective view seen from the rear. As shown in FIG. 3, the cover frame 4 is divided for each side plate 22 of the housing body 2 and is formed into four parts. The cover frame 4 has a connection portion to the front plate 3 and is attached to the housing body 2 by attaching the front plate 3 to the housing body 2. This will be specifically described below.
The front plate 3 is bent rearward at the periphery, and is formed with a skirt portion 31 having a uniform thickness in the back direction. The skirt portion 31 is formed in a double shape, and a slit-like groove 33 for assembling the cover frame 4 is formed between the skirt portion 31 and is provided around the skirt portion 31.

一方、カバー枠４は、ハウジング本体２の側面板２２のそれぞれの面に対応する部位が分割形成され、４つの部材から構成されている。側面板２２の左右側面２２ａ，２２ｂに対応する２つの縦分割片４ａ、天面２２ｃ、底面２２ｄに対応する２つの横分割片４ｂから成り、左右に配置される縦分割片４ａは同一形状の部材が使用され、上下に配置される横分割片４ｂは同一形状の部材が使用され、２種類の部材で形成されている。
各分割片４ａ，４ｂには、溝３３に挿入される舌状の挿入片４１が突設されており、それぞれの挿入片４１が溝３３に挿入されることで、前面板３に連結される。
尚、カバー枠４はハウジング本体２を壁面に埋設せず、壁面上に露出設置する場合に使用され、埋設する場合は取り外されて使用されない。 On the other hand, the cover frame 4 is divided into portions corresponding to the respective surfaces of the side plate 22 of the housing body 2 and is made up of four members. The vertical split pieces 4a corresponding to the left and right side faces 22a and 22b of the side plate 22 and the two horizontal split pieces 4b corresponding to the top face 22c and the bottom face 22d have the same shape. A member is used, and the horizontally divided pieces 4b arranged vertically have the same shape and are formed of two types of members.
Each of the divided pieces 4a and 4b is provided with a tongue-shaped insertion piece 41 that is inserted into the groove 33, and is connected to the front plate 3 by inserting the respective insertion piece 41 into the groove 33. .
The cover frame 4 is used when the housing main body 2 is not installed on the wall surface but is exposed and installed on the wall surface. When the housing frame 2 is embedded, it is removed and not used.

また、縦分割片４ａ及び横分割片４ｂは、隣接する分割片同士で隙間が発生しないよう係合部４２（４２ａ，４２ｂ）が形成されている。縦分割片４ａの係合部４２ａは、横分割片４ｂの係合部４２ｂを挿入して挟持する挟持片を設けて形成され、横分割片４２ｂの係合部４２ｂは、その挟持片に挿入される帯片を設けて形成されている。   The vertical divided pieces 4a and the horizontal divided pieces 4b are formed with engaging portions 42 (42a, 42b) so that no gap is generated between adjacent divided pieces. The engaging portion 42a of the vertical split piece 4a is formed by providing a holding piece for inserting and holding the engaging portion 42b of the horizontal split piece 4b, and the engaging portion 42b of the horizontal split piece 42b is inserted into the holding piece. It is formed by providing a strip to be formed.

そして、横分割片４ｂのハウジング本体２に形成されたノックアウト２４に対応する部位には、ノックアウト２４の位置に合わせて薄肉部４３が形成されている。薄肉部４３を形成するこよで、ノックアウト２４に連通する切り欠き（開口部）を形成し易くしている。   A thin portion 43 is formed in a portion of the horizontal divided piece 4b corresponding to the knockout 24 formed in the housing main body 2 in accordance with the position of the knockout 24. By forming the thin portion 43, a notch (opening) communicating with the knockout 24 is easily formed.

一方、前面板３は、その外郭がハウジング本体２の外郭より大きく形成され、スカート部３１の内側にハウジング本体２が収容されるよう形成されている。図５はカバー枠４を取り外した分電盤ハウジングの斜視図を示し、この図５に示すように前面板３はハウジング本体２より一回り大きく形成されて、連結した際は周囲に段差Ｂが形成される。こうして段差Ｂを設けることで、ハウジング本体２を壁面に埋設した場合に、周囲に発生する壁面との隙間を前面板３により隠すことを可能としている。
また、カバー枠４を取り付けた前面板３をハウジング本体２に取り付ければ、前面板３とハウジング本体２との間の段差Ｂが隠れて段差の無い一様な側面が形成される。 On the other hand, the front panel 3 is formed such that the outer shell is formed larger than the outer shell of the housing main body 2, and the housing main body 2 is accommodated inside the skirt portion 31. FIG. 5 is a perspective view of the distribution board housing from which the cover frame 4 is removed. As shown in FIG. 5, the front plate 3 is formed to be slightly larger than the housing body 2, and when connected, a step B is formed around the periphery. It is formed. By providing the step B in this manner, when the housing main body 2 is embedded in the wall surface, it is possible to hide the gap between the housing body 2 and the surrounding wall surface by the front plate 3.
Further, if the front plate 3 to which the cover frame 4 is attached is attached to the housing main body 2, a step B between the front plate 3 and the housing main body 2 is hidden, and a uniform side surface having no step is formed.

図４は、カバー枠４を前面板３に取り付ける手順を示す後方から見た斜視説明図であり、（ａ）は縦分割片４ａを取り付ける説明図、（ｂ）は横分割片４ｂを取り付ける説明図、（ｃ）は取り付けが完了した状態の説明図をそれぞれ示している。図４では、最初に左右の縦分割片４ａを前面板３に取り付け、その後横分割片４ｂを取り付ける流れを示している。この場合、横分割片４ｂの取り付けは、縦分割片４ａの係合部４２ａに、横分割片の係合部４２ｂを挿入しながらスライドさせて前面板３に連結させる。各分割片４ａ，４ｂは、挿入片４１が溝３３に挿入されて連結される。
そして、このように分割片４ａ，４ｂ同士の当接部に重なり部を設けて係合部４２を形成することで、隙間の発生を防止すると共に、分割片４ａ，４ｂ同士を連結させて一体化を実施している。
尚、取り付け順序は逆でも良く、最初に横分割片４ｂを前面板３に取り付け、その後係合部４２同士を合致させた状態で縦分割片４ａをスライドさせて前面板３に連結しても良い。 4A and 4B are rear perspective views illustrating a procedure for attaching the cover frame 4 to the front plate 3, where FIG. 4A is an explanatory view of attaching the vertical split piece 4a, and FIG. 4B is an explanatory view of attaching the horizontal split piece 4b. FIG. 2C is an explanatory view showing a state in which the mounting is completed. FIG. 4 shows a flow in which the left and right vertical divided pieces 4a are first attached to the front plate 3, and then the horizontal divided pieces 4b are attached. In this case, the horizontal split piece 4b is attached to the front plate 3 by sliding while inserting the horizontal split piece engaging portion 42b into the engaging portion 42a of the vertical split piece 4a. Each of the divided pieces 4a and 4b is connected by inserting the insertion piece 41 into the groove 33.
By forming the engaging portion 42 by providing the overlapping portion at the contact portion between the divided pieces 4a and 4b in this way, it is possible to prevent the occurrence of a gap and to connect the divided pieces 4a and 4b together to form an integral part. Has been implemented.
Note that the mounting order may be reversed. First, the horizontal split piece 4b is mounted on the front plate 3 and then the vertical split piece 4a is slid in a state where the engaging portions 42 are aligned with each other to be connected to the front plate 3. good.

そして、カバー枠４を取り付けて蓋状に形成された前面板３を、ハウジング本体２に対して前方から外挿するように取り付けることで、カバー枠４はハウジング本体２の側面板２２を覆うように配置される。その後、前面板３の左右に設けられたねじ挿通孔３４を使用してねじ止めすれば、ハウジング本体２に前面板３が固定され、同時にカバー枠４も位置決めされ固定される。   The cover frame 4 is attached to the housing body 2 so that the front plate 3 formed in a lid shape and attached to the housing body 2 is externally inserted from the front, so that the cover frame 4 covers the side plate 22 of the housing body 2. Placed in Thereafter, by screwing using the screw insertion holes 34 provided on the left and right of the front plate 3, the front plate 3 is fixed to the housing main body 2, and the cover frame 4 is also positioned and fixed at the same time.

このように、ハウジング本体２をカバー枠４で覆っても、カバー枠４にはハウジング本体２のノックアウト２４の位置に合わせて薄肉部４３が設けられているので、カバー枠４を取り付けてもノックアウト２４を使用した電線の入出が可能である。そして、カバー枠４でハウジング本体２が覆われるため、ハウジング本体２を壁面から露出させても外観的に好ましくできる。
また、前面板３はハウジング本体２より外郭が大きいため、カバー枠４を取り除いてハウジング本体２を壁面に埋設すれば、装着した前面板３によりハウジング本体２と壁面との間の隙間を塞ぐことができ、別途閉塞部材を必要としない。
そして、カバー枠４は前面板３の外郭に一致する大きさを有するため、前面板３を外すだけでカバー枠４の着脱が可能であるし、ハウジング本体２を露出して使用する場合はカバー枠４を取り付けることで、前面板３とハウジング本体２との段差を無くしてすっきりした形状にでき、外観的に好ましい。
加えて、カバー枠４の取り付けは、前面板３に挿入して取り付ける操作のみで良く、ねじ止め等必要なく簡易な操作で取り付けできるし、取り外したカバー枠４は４枚の板片に分割できるため、省スペースで保管できる。 As described above, even when the housing body 2 is covered with the cover frame 4, the thin portion 43 is provided on the cover frame 4 in accordance with the position of the knockout 24 of the housing body 2. It is possible to enter and exit the electric wire using 24. And since the housing main body 2 is covered with the cover frame 4, even if it exposes the housing main body 2 from a wall surface, external appearance can be preferable.
Further, since the front plate 3 has a larger outer shell than the housing body 2, if the cover frame 4 is removed and the housing body 2 is buried in the wall surface, the gap between the housing body 2 and the wall surface can be closed by the mounted front plate 3. And a separate closing member is not required.
Since the cover frame 4 has a size corresponding to the outline of the front plate 3, the cover frame 4 can be attached and detached only by removing the front plate 3. By attaching the frame 4, the step between the front plate 3 and the housing main body 2 can be eliminated to form a neat shape, which is preferable in appearance.
In addition, the cover frame 4 can be attached only by inserting it into the front plate 3 and attaching it. The cover frame 4 can be attached by a simple operation without screwing or the like, and the removed cover frame 4 can be divided into four plate pieces. Therefore, it can be stored in a small space.
