【発明の属する技術分野】
本発明は、前面に開口を有する箱体本体に電気機器を収納し、開口周縁に枠体を取り付け、箱体本体内の配線を配線覆いで被覆して成る分電盤の配線覆いの固定構造に関する。
【０００２】
【従来の技術】
従来、分電盤の配線覆いは、固定用の専用部品を機器取り付け用パネルやレールまたは箱体本体の底面に取り付け、その専用部品によって支持させていた（例えば特許文献１参照。）。また、従来分電盤の製作においては、内機の製作やアッセンブリを行う、いわゆる分電盤製造業者とボックスを製作する業者は別々であったため、内機に属する配線覆いは、箱体本体に取り付けるのではなく、機器取り付けパネルに取り付ける方法が一般的であった。分電盤の箱体本体全体の深さと配線覆い取り付け位置の深さは内部機器により異なる。

【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の配線覆い固定構造では、専用部品が必要であるため、部品にかかる費用が高くなると共に、部品点数の増加によって組み立て時間がかかり組み立て作業費も嵩むという欠点があった。また、使用部品が多くなると、分電盤の重量が多くなり施工に時間がかかっていた。それから、配線覆いを支持する専用部品が結線時に障害となり、作業がしづらくなっていた。また、電線が専用部品に絡まってゆがみを生じ、配線覆いが正常の位置に取り付けられず、配線覆いが内部機器に干渉してしまう虞があった。
【０００５】
【課題を解決するための手段】
そこで本発明は、部品点数を抑え組み立て作業を楽に行える分電盤の配線覆いの固定構造を提供することを目的とし、その構造は、箱体本体には覆い立てを設けず、枠体で配線覆いを支持固定することを特徴とする。
【０００６】
また、枠体の開口周縁に固定穴を有する折曲部を背面板に平行になるよう設けると共に、配線覆いには固定穴と対向する位置にねじ穴を形成し、配線覆いを折曲部にねじ止めにより固定することを特徴とする。
【０００７】
【発明の実施の形態】
本発明に係る配線覆いの固定構造は、箱体本体開口周縁に取り付ける枠の端部に箱体本体の背面に平行に折曲部を設ける。折曲部には固定穴を設け、また配線覆いには固定穴に対向する位置にねじ穴を形成する。配線覆いはねじ穴を固定穴に対向させ、それぞれにねじ止めをし固定する。
【０００８】
【実施例】
本発明に係る配線覆いの固定構造の実施例を図１の添付図面に基づいて説明する。
【０００９】
分電盤１は前面に開口２ａを有する箱体本体２に電気機器を収納し、開口２ａ周縁には枠体３を取り付ける。開口２ａは配線覆い４で施蓋し、電気機器の配線を被覆する。
【００１０】
箱体本体２には従来用いていた覆い立てを設けず、枠体３を加工することによって配線覆い４を支持する。枠体３の開口２ａ周縁には配線覆い４を支持するための折曲部５を形成する。折曲部５は開口の上下端部から分電盤の内部方向に形成し、それぞれの両端に固定穴６を設ける。
【００１１】
配線覆い４は四隅に折曲部５に設けられた固定穴６と対向するようにねじ穴７を形成する。配線覆い４には内部機器の操作ハンドルが突出可能である突出穴４ａが開口され、取り付け作業がしやすいように取っ手４ｂを取り付けても良い。配線覆い４を固定穴６にねじ穴７を対向させて、固定穴６とねじ穴７それぞれに指で回転させてねじ締めできるローレットねじ８で固定する。
【００１２】
本発明に係る配線覆いの固定構造は、図２に示すように、折曲部９を箱体本体１０とは別部品とし、固定用のねじ穴１１を複数個設ける。箱体本体１０に収納される機器の高さによって配線覆いの固定位置をねじ穴１１を選択することによって変更できる。
【００１３】
本発明に係る配線覆いの固定構造は、図１〜図２に示す構造に限定されるものではなく、折曲部を開口の上下ではなく、左右に設けても良い。固定穴の数も三以上設けても良い。また、折曲部９と枠体３は別々に形成するのではなく、一体構造とした枠体でも良い。以上のように、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。
【００１４】
【発明の効果】
以上述べたように、本発明に係る配線覆いの固定構造は、箱体本体には覆い立てを設けず、枠体で配線覆いを支持固定するため、配線覆いを固定するための特別な専用部品が必要なく、部品点数を減らすことができ、組み立て作業も軽減できる。
【００１５】
また、枠体の開口周縁に固定穴を有する折曲部を背面板に平行になるよう設けると共に、配線覆いには固定穴と対向する位置にねじ穴を形成し、配線覆いを折曲部にねじ止めによるため、配線覆いを固定するための特別な専用部品が必要なく、部品点数を減らすことができるので、製造費用を抑えると共に、分電盤全体の重量も軽くなり施工が楽になる。また、部品点数の少ない分、組み立ても簡単になり、組み立て作業が軽減、組み立て加工費も抑えることができる。専用部品が配線の邪魔になることもなく、電線が従来の専用部品を押して発生していたゆがみなどもないため、配線覆いは常に正常な状態で取り付けが可能であり施工後のクレーム等も発生しない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fixing structure of a wiring cover of a distribution board in which an electric device is housed in a box body having an opening on the front surface, a frame is attached to the periphery of the opening, and wiring in the box body is covered with the wiring cover. About.
[0002]
[Prior art]
Conventionally, as a wiring cover of a distribution board, a dedicated component for fixing is attached to a panel for mounting equipment, a rail, or a bottom surface of a box body, and is supported by the dedicated component (for example, see Patent Document 1). In addition, in the conventional production of a distribution board, the so-called distribution board manufacturer and the manufacturer of the box that manufacture and assemble the inner machine were separate from each other, so the wiring cover belonging to the inner machine was attached to the box body. Rather than mounting, it was common to mount it on an equipment mounting panel. The depth of the entire box body of the distribution board and the depth of the wiring cover attachment position differ depending on the internal device.
[0003]

Japanese Patent Application Laid-Open No. 2002-238115
[Problems to be solved by the invention]
However, the conventional structure for fixing the wiring cover of the distribution board in the prior art requires dedicated parts, so that the cost of the parts is high, and the increase in the number of parts increases the assembly time and the assembly work cost. Was. In addition, when the number of parts used increases, the weight of the distribution board increases, and it takes a long time to perform the construction. Then, a dedicated part for supporting the wiring cover becomes an obstacle at the time of connection, and the work becomes difficult. In addition, there is a possibility that the electric wire is entangled with the dedicated component and warps, and the wiring cover is not attached to a normal position, and the wiring cover interferes with the internal device.
[0005]
[Means for Solving the Problems]
Therefore, an object of the present invention is to provide a fixing structure of a wiring cover of a distribution board that can reduce the number of parts and facilitate an assembling operation. The cover is fixedly supported.
[0006]
In addition, a bent portion having a fixing hole on the periphery of the opening of the frame body is provided so as to be parallel to the back plate, and a screw hole is formed in a position facing the fixing hole in the wiring cover, and the wiring cover is formed in the bent portion. It is characterized by being fixed by screwing.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
In the fixing structure of the wiring cover according to the present invention, a bent portion is provided at an end of a frame attached to a peripheral edge of the opening of the box body in parallel with the back surface of the box body. A fixing hole is provided in the bent portion, and a screw hole is formed in the wiring cover at a position facing the fixing hole. The wiring cover has the screw holes facing the fixing holes, and each is screwed and fixed.
[0008]
【Example】
An embodiment of a fixing structure of a wiring cover according to the present invention will be described with reference to the accompanying drawings of FIG.
[0009]
The distribution board 1 accommodates electric devices in a box body 2 having an opening 2a on the front surface, and a frame 3 is attached to the periphery of the opening 2a. The opening 2a is covered with a wiring cover 4 to cover the wiring of the electric device.
[0010]
The wiring cover 4 is supported by processing the frame 3 without providing the cover body conventionally used in the box body 2. A bent portion 5 for supporting the wiring cover 4 is formed around the opening 2 a of the frame 3. The bent portions 5 are formed from the upper and lower ends of the opening toward the inside of the distribution board, and fixed holes 6 are provided at both ends.
[0011]
The wiring cover 4 has screw holes 7 at four corners so as to face the fixing holes 6 provided in the bent portions 5. The wiring cover 4 is provided with a protruding hole 4a through which an operation handle of the internal device can protrude, and a handle 4b may be attached to facilitate the attaching operation. The wiring cover 4 is fixed to the fixing hole 6 with the screw hole 7 opposed to the fixing hole 6 and the knurled screw 8 that can be rotated and finger-tightened to each of the fixing hole 6 and the screw hole 7 with a finger.
[0012]
In the wiring cover fixing structure according to the present invention, as shown in FIG. 2, the bent portion 9 is a separate component from the box body 10, and a plurality of fixing screw holes 11 are provided. The fixing position of the wiring cover can be changed by selecting the screw hole 11 according to the height of the device stored in the box body 10.
[0013]
The structure for fixing the wiring cover according to the present invention is not limited to the structure shown in FIGS. 1 and 2, and the bent portion may be provided on the left and right rather than above and below the opening. The number of fixing holes may be three or more. Further, the bent portion 9 and the frame 3 are not separately formed, but may be a frame having an integrated structure. As described above, changes can be made as appropriate without departing from the spirit of the present invention.
[0014]
【The invention's effect】
As described above, the fixing structure of the wiring cover according to the present invention is a special dedicated component for fixing the wiring cover because the box body is not provided with a cover and the frame body supports and fixes the wiring cover. , The number of parts can be reduced, and the assembling work can be reduced.
[0015]
In addition, a bent portion having a fixing hole on the periphery of the opening of the frame body is provided so as to be parallel to the back plate, and a screw hole is formed in a position facing the fixing hole in the wiring cover, and the wiring cover is formed in the bent portion. Because of the screwing, no special parts for fixing the wiring cover are required, and the number of parts can be reduced, so that the manufacturing cost is reduced, and the weight of the entire distribution board is reduced and the construction is facilitated. In addition, as the number of parts is small, assembling is simplified, assembling work is reduced, and assembling processing costs can be reduced. The dedicated parts do not interfere with the wiring, and the wires are not distorted by pushing the conventional dedicated parts.Therefore, the wiring cover can always be installed in a normal state, and complaints after construction also occur do not do.
