Description

本発明は、たとえば分電盤や配電盤等を収納するためのキャビネットに関するものである。 The present invention relates to a cabinet for storing, for example, a distribution board or a distribution board.

従来、たとえば分電盤や配電盤等を収納するためのキャビネットとしては、特許文献１に記載されているように、前面を除く他の５面を閉塞するキャビネット本体と、当該キャビネット本体の前面開口を開閉する扉体とを備えてなるものが知られている。
また、そのようなキャビネット本体を形成するにあたっては、背板、天板、底板、及び一対の側板を夫々別途成形するとともに、それらの板体を溶接して一体化することにより形成することが多い。そして、板体同士を溶接するにあたっては、図４（ｂ）に示すように、一方の板体の端面を他方の板体の内面側に当接させた状態（たとえば、天板３１の端面を側板３２の内面側に当接させた状態）で、板体同士を隅肉溶接（図４（ｂ）のハッチング部）して一体化していた。 Conventionally, as a cabinet for storing, for example, a distribution board or a distribution board, as described in Patent Document 1, a cabinet body that closes the other five surfaces except the front surface, and a front opening of the cabinet body are provided. What is provided with the door body which opens and closes is known.
Further, in forming such a cabinet body, the back plate, the top plate, the bottom plate, and the pair of side plates are separately formed and are often formed by welding and integrating these plate bodies. . And when welding plate bodies, as shown in FIG.4 (b), the state which made the end surface of one plate body contact | abut to the inner surface side of the other plate body (For example, the end surface of the top plate 31 is used. In the state of being in contact with the inner surface side of the side plate 32), the plate bodies were integrated by fillet welding (hatched portion in FIG. 4B).

しかしながら、上記隅肉溶接により背板、天板、底板、及び一対の側板を一体化しようとすると、溶接箇所となる合わせ面（図４（ｂ）では、側板３２における天板３１の当接箇所が合わせ面となる）として広い面積を確保する必要があるため、キャビネット本体の内部空間における有効スペースが減少するという問題がある。また、溶接箇所の周辺部、特にキャビネット本体の外面に露出した板体の端面には塗装がのりにくいため、当該端面から錆が発生してしまうという問題もある。 However, when the back plate, the top plate, the bottom plate, and the pair of side plates are integrated by the fillet welding, a mating surface that becomes a welding location (in FIG. 4B, the contact location of the top plate 31 on the side plate 32). Therefore, there is a problem that the effective space in the internal space of the cabinet body is reduced. Moreover, since it is hard to apply | coat to the peripheral part of a welding location, especially the end surface of the plate exposed to the outer surface of a cabinet main body, there also exists a problem that rust will generate | occur | produce from the said end surface.

そこで、本発明は、上記問題に鑑みなされたものであって、合わせ面として確保する面積を削減することができ、キャビネット本体の外面に錆も発生しにくいキャビネットを提供しようとするものである。 Therefore, the present invention has been made in view of the above problem, and an object of the present invention is to provide a cabinet that can reduce the area to be secured as a mating surface and hardly cause rust on the outer surface of the cabinet body.

上記目的を達成するために、本発明に係るキャビネットは、前面を除く他の５面を閉塞するキャビネット本体と、キャビネット本体の前面開口を開閉する前扉とを備えたキャビネットであって、キャビネット本体は、複数の板部同士の当接部を溶接することによって形成されており、当接部においては、一方の板部の端面上に、他方の板部の外縁部における内面側が当接した状態となっており、両板部の端面が、露出しないように溶接箇所により覆われていることを特徴とする。 In order to achieve the above object, a cabinet according to the present invention is a cabinet comprising a cabinet body that closes the other five surfaces except the front surface, and a front door that opens and closes the front opening of the cabinet body. Is formed by welding the contact portions of a plurality of plate portions, where the inner surface side of the outer edge portion of the other plate portion is in contact with the end surface of one plate portion. The end faces of both plate portions are covered with welded portions so as not to be exposed.

本発明によれば、当接部においては、一方の前記板部の端面上に、他方の前記板部の外縁部における内面側が当接した状態となっており、両前記板部の端面が、露出しないように溶接箇所により覆われている。したがって、従来のキャビネットと比べると、溶接箇所において合わせ面として確保する面積を削減することができ、キャビネット本体の内部空間における有効スペースを増大することができる。また、両板部の端面が溶接箇所に覆われて露出しない上に溶接箇所がＲ状となることから、当該溶接箇所及びその周辺部に塗装がのりやすく、従来の如く溶接箇所の周辺部から錆が発生するという事態を抑制することができる。さらに、全ての板部を別個に準備するものと比べて溶接箇所を少なくすることができ、組み立て作業の簡易化を図ることができる。 According to the present invention, in the contact portion, the inner surface side of the outer edge portion of the other plate portion is in contact with the end surface of one of the plate portions, and the end surfaces of both the plate portions are It is covered with welded parts so as not to be exposed. Therefore, compared with the conventional cabinet, the area to be secured as the mating surface at the welding location can be reduced, and the effective space in the internal space of the cabinet body can be increased. In addition, since the end surfaces of both plate portions are not exposed because they are covered with the welded portion, and the welded portion has an R shape, it is easy to paint on the welded portion and its peripheral portion. The situation where rust occurs can be suppressed. Furthermore, compared with what prepares all the board parts separately, a welding location can be decreased and an assembly operation can be simplified.

FIG. 3 is an explanatory view showing a state where the cabinet body 2 is developed.
The cabinet main body 2 is a metal plate-like member, and includes a back plate portion 11 positioned substantially at the center, a top plate portion 12 protruding upward from the back plate portion 11, and protruding downward from the back plate portion 11. It is formed in a single plate shape having a bottom plate portion 13 and a pair of side plate portions 14 and 14 protruding from the back plate portion 11 to the left and right sides. Note that bent portions 20a, 20b, and 20c that are bent and raised are provided on the outer edge portions of the top plate portion 12, the bottom plate portion 13, and the side plate portions 14 and 14, respectively. The bent portions 20a to 20c become a series when the cabinet body 2 is assembled as will be described later, and as shown in FIG. 2, a draining portion 20 surrounding the front opening 4 of the cabinet body 2 is formed. Yes.

そして、上記キャビネット本体２は、背板部１１に対し、天板部１２、底板部１３、及び側板部１４、１４を夫々前側へ折り曲げるとともに、背板部１２と側板部１４、１４との当接部１５（図１や図２に示す）、及び底板部１３と側板部１４、１４との当接部１５を夫々溶接することによって組み立てられる。この溶接にあたっては、図４（ａ）に示すように、一方の板部の端面を半分程度露出させつつ、当該一方の端面上に他方の板部の外縁部における内面側を当接させた状態（たとえば、側板部１４の端面を半分程度露出させるような状態で、側板部１４の端面上に天板部１２の外縁部における内面側を当接させた状態）とする。そして、該当接部１５に沿ってレーザー溶接を行い、両板部の端面を溶接箇所（図４（ａ）のハッチング部）により覆う。 The cabinet body 2 bends the top plate portion 12, the bottom plate portion 13, and the side plate portions 14, 14 forward with respect to the back plate portion 11, and also contacts the back plate portion 12 with the side plate portions 14, 14. The contact portion 15 (shown in FIGS. 1 and 2) and the contact portion 15 between the bottom plate portion 13 and the side plate portions 14 and 14 are assembled by welding. In this welding, as shown in FIG. 4 (a), while the end surface of one plate portion is exposed about half, the inner surface side of the outer edge portion of the other plate portion is brought into contact with the one end surface. (For example, a state in which the end surface of the side plate portion 14 is exposed about half and the inner surface side of the outer edge portion of the top plate portion 12 is in contact with the end surface of the side plate portion 14). And laser welding is performed along the applicable contact part 15, and the end surface of both board parts is covered with a welding location (hatching part of Fig.4 (a)).

以上のような構成を有するキャビネット１によれば、キャビネット本体２が、背板部１１、天板部１２、底板部１３、及び側板部１４、１４を有する一枚板状に形成されている。そして、当該キャビネット本体２は、背板部１１に対して、天板部１２や底板部１３、側板部１４、１４を折り曲げ、天板部１２と側板部１４、１４との当接部１５、及び底板部１３と側板部１４、１４との当接部１５を溶接することにより組み立てられる。また、当接部１５の溶接については、一方の板部の端面を半分程度露出させつつ、当該一方の端面上に他方の板部の外縁部における内面側を当接させた状態とし、該当接部１５に沿ってレーザー溶接を行い、両板部の端面を溶接箇所により覆うようにした。したがって、従来のキャビネットと比べると、溶接箇所において合わせ面として確保する面積を削減することができる（上記実施形態では、合わせ面の面積を従来の略半分とすることができる）ことになり、キャビネット本体２の内部空間における有効スペースを増大することができる。また、両板部の端面が溶接箇所に覆われて露出しない上に溶接箇所がＲ状となることから、当該溶接箇所及びその周辺部に塗装がのりやすく、従来の如く溶接箇所の周辺部から錆が発生するという事態を抑制することができる。さらに、キャビネット本体２を、背板部１１、天板部１２、底板部１３、及び側板部１４、１４を有する一枚板状に形成したことで、全ての板部を別個に準備するものと比べて溶接箇所を少なくすることができ、組み立て作業の簡易化を図ることができる。 According to the cabinet 1 having the above configuration, the cabinet body 2 is formed in a single plate shape having the back plate portion 11, the top plate portion 12, the bottom plate portion 13, and the side plate portions 14 and 14. And the said cabinet main body 2 bend | folds the top-plate part 12, the bottom-plate part 13, and the side-plate parts 14 and 14 with respect to the backplate part 11, and the contact part 15 of the top-plate part 12 and the side-plate parts 14 and 14, And it is assembled by welding the contact part 15 of the baseplate part 13 and the side-plate parts 14 and 14. FIG. For welding of the contact portion 15, the end surface of one plate portion is exposed about half and the inner surface side of the outer edge portion of the other plate portion is contacted on the one end surface. Laser welding was performed along the portion 15 so that the end faces of both plate portions were covered with the welded portion. Therefore, compared with the conventional cabinet, the area to be secured as the mating surface at the welded portion can be reduced (in the above embodiment, the area of the mating surface can be reduced to about half of the conventional size), and the cabinet The effective space in the internal space of the main body 2 can be increased. In addition, since the end surfaces of both plate portions are not exposed because they are covered with the welded portion, and the welded portion has an R shape, it is easy to paint on the welded portion and its peripheral portion. The situation where rust occurs can be suppressed. Furthermore, the cabinet body 2 is formed in a single plate shape having the back plate portion 11, the top plate portion 12, the bottom plate portion 13, and the side plate portions 14 and 14, so that all the plate portions are separately prepared. Compared with this, it is possible to reduce the number of welding locations, and to simplify the assembling work.
