DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board which is constructed by placing various electric devices on a device mounting plate and storing them in a box body.

[0002]

2. Description of the Related Art In the prior art, when electric equipment is housed in a distribution board, as shown in FIG.
Is mounted and fixed on the device mounting plate 32. Since the device mounting plate 32 is bent, the central portion does not adhere to the back plate 33 and is attached to the box body 34 in a floating state. The attachment of the device mounting plate 32 to the box body 34 is fixed to the back plate 33 of the box body 34 by screws or the like. In this way, the electric equipment was stored in the distribution board.

[0003]

However, according to the above-mentioned prior art, the equipment mounting plate is mounted on the box body with its central portion floating from the back plate of the box body, so that the equipment mounted on the equipment mounting plate can be mounted. Due to the weight of the device, the device mounting plate may be bent or vibration may be easily transmitted, which may lead to malfunction of the device.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for bending an equipment mounting plate on which electrical equipment is mounted and preventing the electrical equipment from being bent .
For the purpose of preventing vibration, in a distribution board in which a device mounting plate to which various electric devices are mounted is housed in a box, an end of the device mounting plate is directed toward a back plate of the box body. A bent portion is provided, the bent portion is extended to the vicinity of the back plate, and the device mounting plate is supported at a plurality of support points.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A distribution board is constructed by housing various electric devices in a box body. The electric devices are mounted and fixed on a device mounting plate, and the device mounting plate is attached to the box body. Attach to the back plate. The device mounting plate is provided with a bent portion by bending both ends, and the bent portion contacts the back plate, can support the device mounting plate, and prevents the device mounting plate from bending or vibrating.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of the distribution board according to the present invention is shown in FIGS.
Explanation will be made based on the attached drawing of FIG.

FIG. 1 is a sectional view showing the structure of a distribution board according to the present invention. The electric device 2 is housed in the box body 1, and the inner device 3 covers the electric device 2 and the wiring portion, and the door 4 covers the opening of the box body 1.

When the electric equipment 2 is stored in the box body 1, it is placed and fixed on the equipment mounting plate 5. Rails 7 for mounting the device mounting plate 5 are provided on the left and right sides of the back plate 6 of the box body 1. The device mounting plate 5 is formed by bending both left and right ends into an L-shaped cross section and fixing the bent portion 8 to the rail 7, thereby mounting the device mounting plate 5 to the box body 1.

A bent portion 8 is provided by bending the upper and lower ends of the device mounting plate 5. The bent portion 8 extends substantially at the center, and its tip is in contact with the back plate 6 of the box body 1, and supports the device mounting plate 5 at a plurality of support points. Since the bent portion 8 supports the device mounting plate 5, when the electric device 2 is mounted on the device mounting plate 5, it is possible to prevent the device mounting plate 5 from bending or being easily transmitted with vibration.

As shown in FIG. 2, a base 10 is mounted on the box body 9 of the distribution board, and a device mounting plate 12 having an electric device 11 mounted on the base 10 is fixed. There is also. In such a case, the equipment mounting plate 1
Since the second bent portion hits the base 10, a concave notch 14 may be provided in the broken line A in FIG. 2 as shown in FIG. 3 so that the bent portion 13 can be cut off .

FIGS. 4 and 5 show a modified embodiment of the distribution board according to the present invention. The shape of the notch 15 for cutting off the bent portion of the device mounting plate is not limited to a concave shape, but may be a V shape as shown in FIG.

As shown in FIG. 5, the position of the notch for cutting off the bent portion 17 of the equipment mounting plate 16 is as follows.
A plurality of bases 18 may be provided so that they can be changed according to the height of the base 18.

The structure of the distribution board according to the present invention is shown in FIGS.
It is not limited to those shown in, for example,
The bent portion of the device mounting plate may be bent instead of being cut off, and may be appropriately changed without departing from the spirit of the present invention.

[0014]

As described above, according to the present invention, the end of the equipment mounting plate is bent in the direction of the back plate of the box body to provide a bent portion, and the bent portion is extended to the vicinity of the back plate. However, by supporting the device mounting plate at the plurality of support points, even if the electric device is mounted on the device mounting plate, it can be reliably supported by the bent portion, and the device mounting plate can be prevented from bending. In addition, since the device mounting plate is stable , vibration from electric devices can be prevented.
