DESCRIPTION OF THE PREFERRED EMBODIMENTS In a distribution board box according to the present invention, a device such as a breaker is placed on a device mounting plate and screwed. The device mounting plate is bent substantially at the center of the device mounting plate so as to prevent the tip of the screw from jumping out on the rear surface, and a bulging flat portion is provided. A screw hole is formed in the bulging flat portion, and the device is mounted there.

Further, the cover of the distribution board box according to the present invention has a front plate and left and right upper and lower side plates formed integrally with each other, and covers the device by facing the device mounting plate on which the device is mounted. Cover. The hook provided on the upper end of the device mounting plate is inserted into the fitting portion provided on the end of the upper plate of the cover, and then screwed to fix the cover to the device mounting plate.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a distribution board according to the present invention will be described with reference to FIGS.

As shown in FIG. 1, a device 1 is directly mounted on a device mounting plate 2. Equipment mounting plate 2
As shown in FIGS. 2 and 3, a substantially central portion is bent to have a bulging flat portion 3, a screw hole 4 is formed in the bulging flat portion 3, and the device 1 is formed in the bulging flat portion 3. When the screws are screwed, the screws come out from the back of the device mounting plate 2 and are mounted on the wall surface of the distribution board box 5.
The tip of the screw does not hit the wall when attaching the. On the bulging flat portion 3 of the device mounting plate 2,
Only the screw hole 4 facing the device 1 to be mounted is machined, and the device 1 is screwed into the screw hole 4.

The both ends of the equipment mounting plate 2 are bent to form the wire stoppers 6. As shown in FIGS.
The electric wire 7 connected to the electric wire 7 hits the electric wire stopper 6 and fits within the width of the distribution board box 5 without any special operation. As shown in FIG. 6, the distribution board box 5 is configured by covering with a cover 8 or the like.

Since only the screw hole 4 of the device 1 to be mounted is provided in the bulging flat portion 3 of the device mounting plate 2, it is easy to assemble and the work can be simplified and the assembling time can be shortened. Conventionally, the installation of the distribution board was heavy, so the inner unit was removed from the box, the box was attached to the wall first, and then the inner unit was reinstalled again. Because it is lightweight, it can be installed without removing the internal unit.

As a second embodiment of the distribution board according to the present invention,
As shown in FIG. 1, the device 1 is directly mounted on the device mounting plate 2. Therefore, the device mounting plate 2 is shown in FIGS.
As shown in the figure, the substantially central portion is bent to have a bulging flat portion 3, a screw hole 4 is formed in the bulging flat portion 3, and a screw is formed when the device 1 is screwed to the bulging flat portion 3. Comes out from the back of the box,
When the distribution board box 5 is mounted on the wall, the tips of the screws do not hit the wall.

Only the screw hole 4 facing the device 1 to be mounted is machined on the bulging flat portion 3 of the device mounting plate 2. The device 1 is screwed into the screw hole 4 and covered with a cover 9 as shown in FIG. The cover 9 is formed by integrally forming a front plate 11 and upper, lower, left and right side plates 12. As shown in FIG. 8, fitting portions 13 are provided at upper and lower ends of the cover 9, and hook portions 14 are provided at upper and lower plate ends of the device mounting plate 2. The hook portions 14 are inserted into the fitting portions 13, and the device 1 is connected. Cover. At the lower end of the front plate of the cover 9, a screw hole 15 is provided, and a knurled screw is inserted to fix the cover 9 to the device mounting plate 2.

As a third embodiment of the distribution board according to the present invention,
For a structure in which the screw for mounting the device in the screw hole provided on the device mounting plate does not protrude to the back surface, for example, only the screw hole 16 may be depressed as shown in FIG. It can be changed appropriately within a range not to be performed. Since the screw hole 16 is provided in the recessed portion, the screw 17 does not project when the screw 17 is inserted, and the projection of the screw 17 does not interfere with the wall surface when the distribution board is mounted on the wall surface.

Further, the method of fixing the cover to the device mounting plate is not limited to the method of inserting the hook portion provided on the device mounting plate into the fitting portion of the cover as shown in the second embodiment. Can be changed as appropriate without departing from the spirit of the present invention.

[0017]

As described above, the distribution board according to the present invention has an equipment mounting plate for mounting equipment and a cover for covering and covering the equipment constituting the distribution board mounted on the equipment mounting plate. Since the device mounting plate has a bulging flat portion by bending the substantially central portion, forming a screw hole in the bulging flat portion, and bending both end portions to form an electric wire stopper, When assembling the distribution board, the screw holes to be used are limited, so that the assembling time can be shortened and the manufacturing cost can be reduced. By greatly reducing the number of components, the weight of the distribution board can be reduced, the construction cost can be reduced, and the manufacturing cost can be reduced. Also,
The wire stops at the wire stop and does not protrude beyond the width of the box, so there is no need to put the wires in the box and the cover is easy to close.

Further, the cover is formed integrally with the front plate and the upper, lower, left and right side plates, and a fitting portion and a hook portion are provided at positions facing each other near the upper and lower ends of the cover and the device mounting plate, and the hook portion is fitted. After inserting it into the department
To fix with screws, remove the cover at the time of wiring work,
Since there are no upper, lower, left and right side plates, there is no obstacle and it is easy to construct. By greatly reducing the number of components, the weight of the distribution board can be reduced, the construction cost can be reduced, and the manufacturing cost can be reduced.
Also, since the wires stop at the wire stop and do not protrude beyond the width of the box, there is no need to put the wires in the box,
The cover is easy to close.
