Abstract

PROBLEM TO BE SOLVED: To secure sufficient strength without using components for exclusive use by fixing an intermediate section of a rail for installing an inner machine to a rail supporting metal fitting 5 which is installed at an intermediate section of a main body 2 of a box and fixing the rail for installing an inner machine with a plurality of screw holes which are formed in a column fixing metal fitting installed on a column located at an intermediate section of the box. SOLUTION: An intermediate section of a rail for installing an inner machine 3 is fixed to a rail supporting metal fitting 5 installed at an intermediate section of a main body 2 of a box. Then, a column fixing metal fitting 6 is installed on the rail for installing an inner machine 3. In the column fixing metal fitting 6, screw holes 6a for installing the rail for installing an inner machine 3 on the metal fitting 6 are made at a plurality of places. The rail for installing an inner machine 3 is fixed with any screw hole 6a and thereby the width of the main body 2 of the box can be varied. By this method, there is no necessity of preparing component for exlusive use such as a rail for installing a column at an intermediate section of the box and thereby the complexity in component administration can be lessened and then the manufacturing cost can be reduced. In addition, sufficient strength can be secured.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an intermediate support for mounting a plurality of wiring cover plates on a distribution board in a vertically divided manner.

[0002]

2. Description of the Related Art Conventionally, the structure of an intermediate column for vertically dividing and installing a wiring cover plate of a distribution board is as follows.
There was what was shown in FIGS. That is, columns 33 are erected in the vicinity of the four corners of the back plate of the box body 32 of the distribution board 31, and the upper and lower ends of the inner unit mounting rails 34 are fixed to these columns 33 to fix the inner unit mounting rails 34. An intermediate column (not shown) is erected in the intermediate section, and the wiring cover plate 35 is placed on the intermediate column.
Was placed and fixed.

As shown in FIGS. 7 to 9, this distribution board 31
When changing the box body 32 to a box body 32A having a large width by using the inner machine of the same as it is, the inner machine mounting rail 3 is used.
Attach the rail 36 for mounting the intermediate column in parallel with 4a,
The intermediate support column 37 is erected on the intermediate support column mounting rail 36, and the wiring covering plate 38 is placed and fixed on the intermediate support column 37.

[0004]

However, according to the above-mentioned prior art, the distribution board 31 requires the dedicated intermediate-portion mounting rail 36 for changing the width of the box body, and the parts management is complicated. It had the drawback of increasing costs. Further, since the rails for mounting the inner unit 34a and the rails for mounting the middle column support 36 are fixed only at the upper and lower ends, the rails roll due to the weight of the inner unit, and the strength of the distribution board 31 becomes insufficient. It was

[0005]

In view of the above problems of the conventional distribution board, the object of the present invention is to eliminate the need for dedicated parts,
(EN) Provided is a distribution board which can reduce the complexity of parts management and reduce the manufacturing cost, and has sufficient strength. An inner unit mounting rail that is mounted on the box body, an inner unit that is mounted on the inner unit mounting rail, and a plurality of wiring covering plates that cover the opening of the box body to which the inner unit is mounted, Upper struts and lower struts for fixing the wiring cover plate to the upper and lower parts of the box body, an intermediate stanchion for fixing at a plurality of adjacent wiring cover plates, and the box body covered with the wiring cover plate. In a distribution board configured with a door body that covers the opening of, the middle support column fixes the middle part of the inner machine mounting rail to a rail support fitting provided in the middle part of the box body, Attach the column fixing bracket to the inner unit mounting rail, and fix the column The box is formed by attaching an intermediate support to the metal fitting, forming a plurality of screw holes for mounting the inner machine mounting rail on the pillar fixing metal fitting, and fixing the inner machine mounting rail by screwing with any screw hole. To change the width of the body.

Further, in the distribution board, a screw hole for mounting a strut fixing bracket is provided at a plurality of places on the intermediate strut, and the strut fixing bracket is screwed and fixed by an arbitrary screw hole, whereby the height of the box main body is increased. Is to change.

In the distribution board, a bent portion is provided at the base end of the intermediate column, and the bent portion and the back plate of the box body are brought into contact with each other.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Since the rails for mounting the internal unit are screwed and fixed by arbitrary screw holes of the pillar fixing fitting, the width of the box body can be changed.

Further, since the support fixtures are screwed and fixed in any screw holes of the intermediate support, the height of the box body can be changed.

Further, since the bent portion of the base end portion of the intermediate portion column comes into contact with the back plate of the box body, the strength of the distribution board is sufficiently secured.
