Abstract

PROBLEM TO BE SOLVED: To provide a sufficient strength, to prevent the deformation of a case main body with the weight of a transformer and to make the attachment of the transformer easy by providing and fixing angles in parallel with the depth direction at the bottom part of the case main body, and making it possible to mount and attach the transformer on the angle. SOLUTION: At a bottom part 6 of a case main body 2, a thin-type channel base 7 is provided as a unitary body with the case main body 2. Angles 8 are provided in parallel with the depth direction and fixed. A transformer 9 is mounted and attached on the angles 8. Thus, the attaching work of the transformer 9 becomes easy, and the strength of the case main body 2 is increased. Therefore, the deformation of the case main body 2 with the weight of the transformer is avoided. Furthermore, even when the channel base 7 is required, the base of the compact configuration can be used. Therefore, the manufacturing cost can be decreased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to improvement of the structure of a box for housing electrical equipment for housing a transformer.

[0002]

2. Description of the Related Art Conventionally, a box for housing an electric device, which mainly houses a transformer, has been as shown in FIGS. That is, the electrical equipment storage box 21 is the box body 2
2 is provided with an opening 23 on the front surface, and the opening 23 is covered with a door (not shown).
The transformer 26 is placed so as to abut the back plate 25 and the L-shaped mounting stay 27 mounted on the upper surface of the transformer 26 is screwed and fixed to the back plate 25 of the box body 22 by the screw 28. The front side of 26 was fastened and fixed to the draining part 29 of the box body 22 with bolts 30 and nuts 31.

Further, as shown in FIGS. 6 to 7, a box body 41 for accommodating electric equipment is provided with an opening 43 on the front surface of a box body 42, and the opening 43 is provided by a door (not shown). It is made up of a lid and the transformer 46 is placed on the bottom portion 44 of the box body 42.
The bottom surface of the transformer 46 was fixed by tightening the bolt 50 and the nut 51.

[0004]

However, in the electric equipment housing box 21 shown in FIGS. 4 to 5, the installation work of the transformer 26 is complicated, and the transformer 26 is installed in the box body 2
Since the transformer 26 is fixed to the water draining portion 29, the weight of the transformer 26 is unevenly applied to the water draining portion 29 of the box body 22.
However, there is a drawback that the box body 22 centering around may deform.

Further, in the electric equipment housing box 41 shown in FIGS. 6 to 7, since it is necessary to allow the bolt 50 to escape, a relatively large channel base 52 is required, and the manufacturing cost increases accordingly. was there.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional electrical equipment housing box, an object of the present invention is to provide a sufficient strength and prevent the box body from being deformed by the weight of the transformer.
Further, it is an object of the present invention to provide a box body for accommodating an electric device, which is easy to attach a transformer and is inexpensive, and which has an opening at least on the front surface of the box body and which is covered with a door. In the storage box, angles are arranged in parallel in the depth direction on the bottom of the box body, and the angles are fixed so that the transformer can be mounted and mounted on the angles.

Further, in the electric device storage box,
The angle is provided with a transformer mounting hole having a long hole shape.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A transformer is placed on an angle at the bottom of a box body of an electrical equipment housing box, and is tightened and fixed with bolts and nuts at appropriate positions.

[0009]

1 to 3 show an embodiment of a box for housing an electric device according to the present invention. Hereinafter, the present invention will be described with reference to these drawings.

The box 1 for housing electrical equipment comprises an opening 3 on the front surface of a box body 2 and a door 5 rotatably attached to a hinge 4 for covering the opening 3. On the bottom 6 of the box body 2, a thin channel base 7 is provided integrally with the box body 1, and angles 8 are arranged side by side in the depth direction and fixed, and a transformer 9 is mounted on the angle 8. To do.

The transformer 9 is placed on the angle 8 of the bottom portion 6 of the box body 2 of the electrical equipment housing box 1, and is fixed by bolts and nuts at appropriate positions.

If the angle 8 is provided with the elongated hole-shaped transformer mounting hole 8a, it becomes possible to mount the transformers 9 having different mounting dimensions within the range of the dimension of the elongated hole.

The channel base 7 is not always necessary for the construction of the present invention, and is appropriately provided integrally with the box body 2 in consideration of the weight of the transformer and the like. There is no problem even if 8 is attached.

[0014]

As described above, the box for housing electrical equipment according to the present invention is provided with an opening at least on the front surface of the box body,
In a box for storing electric equipment, which is formed by covering the opening with a door, an angle is provided in parallel in the depth direction at the bottom of the box body, and a transformer can be placed and mounted on the angle. As a result, the work of mounting the transformer is facilitated, and the strength of the box body is increased, so that the weight of the transformer does not deform the box body. Further, even when a channel base is required, a small size is sufficient, which has an effect of reducing manufacturing cost.

Further, in the box for housing the electric device,
Providing a transformer mounting hole having a long hole shape in the angle has an effect that transformers having different mounting dimensions can be mounted within the range of the dimension of the long hole.
