Description

本発明は、各辺を一つ以上の部材で構成し、四辺は部材を組み合わせることにより構成する分電盤の筺体の構造に関するものである。 The present invention relates to a structure of a housing of a distribution board in which each side is constituted by one or more members and four sides are constituted by combining the members.

分電盤は、筺体に主幹ブレーカや分岐ブレーカといった電気機器を配列して構成される。従来筺体は、電気機器の配置部分は一体に形成しており、背面部は通線や通気のための穴を形成している。筺体に収納される機器の種類や数により筺体の大きさが変わり、出荷要請に対応できるように、何種類かの筺体を在庫していた。
特開２００２−１３５９４３号公報 The distribution board is configured by arranging electrical devices such as a main breaker and a branch breaker in a housing. In the conventional case, the arrangement part of the electric device is integrally formed, and the back part is formed with a hole for a line or ventilation. Depending on the type and number of devices housed in the chassis, the size of the chassis changed, and several types of chassis were in stock so that they could respond to shipping requests.
JP 2002-135943 A

筺体は、壁面に取り付けられるときと同じ状態で在庫されているため、在庫のスペースが多く必要で、スペースを確保するのも困難であり、スペースの費用も多く必要であった。また、種々在庫しなくてはならず、在庫管理に大きな手間が掛かっていた。また、筺体の製造費用も高くかかるという欠点があった。 Since the housings are stocked in the same state as when they are attached to the wall surface, a lot of stock space is required, it is difficult to secure the space, and the space cost is also high. In addition, various stocks had to be stocked, and it took a lot of work to manage the stock. In addition, the manufacturing cost of the housing is high.

以上の問題点に鑑み、本発明は、簡単な構造で、容易に組み立てられる住宅用分電盤の筺体を提供することを目的とし、その構造は、部材の端部には、隣接する部材と互いに係合するように少なくとも一ヶ所に係合部及び係合受け部を設け、部材は、隣接する部材の係合部と係合受け部とを互いに係合させて接続状態とすると共に、係合受け部は、先端を筺体の内側から外側へ向かって傾斜を形成したことを特徴とする。 In view of the above problems, an object of the present invention is to provide a housing for a housing distribution board that can be easily assembled with a simple structure, and the structure includes an adjacent member at an end of the member. An engagement portion and an engagement receiving portion are provided in at least one place so as to engage with each other, and the members are brought into a connected state by engaging the engagement portions and the engagement receiving portions of adjacent members with each other. The receiving portion is characterized in that the tip is inclined from the inside to the outside of the housing.

また、接続状態である部材を螺着固定し筺体を構成することを特徴とする。 Further, the housing is configured by screwing and fixing members in a connected state.

本発明に係る筺体の構造は、部材の端部には、隣接する部材と互いに係合するように少なくとも一ヶ所に係合部及び係合受け部を設け、部材は、隣接する部材の係合部と係合受け部とを互いに係合させて接続状態とすると共に、係合受け部は、先端を筺体の内側から外側へ向かって傾斜を形成したため、筺体を分割された部材を組み合わて構成することで、筺体の在庫スペースを縮小できる。また、組み立ては、隣接する部材の係合部を互いに係合させるだけで、容易であるので、分割したことで作業性が悪くなることもない。 In the structure of the housing according to the present invention, the end portion of the member is provided with an engagement portion and an engagement receiving portion in at least one position so as to engage with the adjacent member, and the member is engaged with the adjacent member. The engagement receiving portion is connected to each other by engaging with each other, and the engagement receiving portion is formed by combining the members divided into the casing because the tip is inclined from the inside to the outside of the casing. By doing so, the inventory space of the chassis can be reduced. In addition, the assembly is easy by simply engaging the engaging portions of adjacent members with each other, so that the workability does not deteriorate due to the division.

また、接続状態である部材を螺着固定し筺体を構成するため、筺体を分割された部材を組み合わて構成することで、筺体の在庫スペースを縮小できる。また、組み立ては、隣接する部材の係合部を互いに係合させるだけで、容易であるので、分割したことで作業性が悪くなることもない。隣接する部材は螺着することができるため、確実に固定可能である。 In addition, since the casing is configured by screwing and fixing the members in the connected state, the inventory space of the casing can be reduced by configuring the casing in combination with the divided members. In addition, the assembly is easy by simply engaging the engaging portions of adjacent members with each other, so that the workability does not deteriorate due to the division. Since adjacent members can be screwed together, they can be reliably fixed.

本発明に係る筺体の構造の実施例を図１〜図５の添付図面に基いて説明する。 An embodiment of the structure of the housing according to the present invention will be described with reference to the accompanying drawings of FIGS.

分電盤は、主幹ブレーカや分岐ブレーカ等の電気機器を筺体に配列して構成される。筺体１を少なくとも上部部材２、下部部材３、左部材４、右部材５とを組み合わせて形成する。これらの部材の係合構造は、互いに接続する部分にそれぞれ係合部６及び係合受け部７を設ける。係合方法は、一つの部材に正面側から差し込んで係合させるものである。 The distribution board is configured by arranging electrical devices such as a main breaker and a branch breaker in a housing. The housing 1 is formed by combining at least the upper member 2, the lower member 3, the left member 4, and the right member 5. The engagement structure of these members is provided with an engagement portion 6 and an engagement receiving portion 7 at portions connected to each other. The engaging method is to insert and engage one member from the front side.

上部部材２と右部材５との係合部分で説明する。上部部材２には、右部材５と接する壁体８を形成し、この壁体８に係合部６を設ける。図５においては、櫛状にリブを形成し係合部６を設け、壁体８の強度を増強させている。 The engagement portion between the upper member 2 and the right member 5 will be described. The upper member 2 is formed with a wall body 8 in contact with the right member 5, and an engaging portion 6 is provided on the wall body 8. In FIG. 5, ribs are formed in a comb shape and the engaging portions 6 are provided to increase the strength of the wall body 8.

一方、右部材５には、筺体１の壁面の上部部材２に設けられた係合部６に対向する位置に係合受け部７を突設する。係合受け部７の先端は、筺体１の内側から外側へ下る傾斜９を設ける。 On the other hand, on the right member 5, an engagement receiving portion 7 protrudes at a position facing the engagement portion 6 provided on the upper member 2 of the wall surface of the housing 1. The tip of the engagement receiving portion 7 is provided with a slope 9 that descends from the inside to the outside of the housing 1.

上部部材２の係合部６に右部材５の係合受け部７を正面から差し込むように係合させ、上部部材２と右部材５とを接続する。上部部材２と右部材５との接続動作の際、係合受け部７に設けられた傾斜９により、部材間の位置決めができることはもちろん、上部部材２が右部材５の壁面１０ａに沿う方向に進み、上部部材２と右部材５との壁面１０ｂ，１０ａが同一面上に形成され、接続部の凹凸が発生しない。 The engagement member 6 of the right member 5 is engaged with the engagement portion 6 of the upper member 2 so as to be inserted from the front, and the upper member 2 and the right member 5 are connected. During the connecting operation of the upper member 2 and the right member 5, the inclination 9 provided in the engagement receiving portion 7 enables positioning between the members, and the upper member 2 is in a direction along the wall surface 10a of the right member 5. As a result, the wall surfaces 10b and 10a of the upper member 2 and the right member 5 are formed on the same surface, and the unevenness of the connection portion does not occur.

以上、部材の接続を上部部材２と右部材５とを例として示したが、上部部材２と左部材４、左部材４と下部部材３、下部部材３と右部材５も同様な形状に構成し、それぞれを係合させることによって一つの筺体１を構成する。 Although the upper member 2 and the right member 5 are shown as examples of connection of the members, the upper member 2 and the left member 4, the left member 4 and the lower member 3, and the lower member 3 and the right member 5 are configured in the same shape. And one housing 1 is comprised by engaging each.

部材間の接続部は、部材同士が重なることになり、さらに係合部としてのリブが設けられるので、強度も確保でき、安全な分電盤の筺体を提供することが可能となる。 The connecting portions between the members are overlapped with each other, and the ribs are further provided as the engaging portions, so that the strength can be ensured and a safe distribution board housing can be provided.

筺体に収める機器によって、筺体の寸法を変える必要があるが、このときは、それぞれ部材を交換することで対応する。できるだけ、部材は共用することで、部品管理の手間や費用を抑える。 Although it is necessary to change the dimension of a housing by the apparatus accommodated in a housing, at this time, it respond | corresponds by replacing each member. By sharing parts as much as possible, the labor and cost of parts management are reduced.

本発明の請求項２に係る筺体の構造について述べる。上部部材２と右部材５の接合部を例に説明する。上部部材２の壁体８に囲まれた部分と、右部材５の壁面１０ａに囲まれた部分とにそれぞれ、上部部材２と右部材５とを接続したときに対向する位置に螺子が挿通可能である螺子挿通孔１１を設ける。請求項１に記載の通り、部材をそれぞれ係合させて筺体１を構成した状態で、螺子挿通孔１１に螺子を挿通し、締め付けることで、部材間の接着をさらに堅固なものにする。 The structure of the housing according to claim 2 of the present invention will be described. A description will be given of a joint portion between the upper member 2 and the right member 5 as an example. Screws can be inserted into positions facing each other when the upper member 2 and the right member 5 are connected to the portion surrounded by the wall 8 of the upper member 2 and the portion surrounded by the wall surface 10a of the right member 5, respectively. A screw insertion hole 11 is provided. As described in claim 1, in a state where the members are engaged with each other and the housing 1 is configured, the screws are inserted into the screw insertion holes 11 and tightened, thereby further strengthening the adhesion between the members.
