Description

[Detailed Description of the Invention] The present invention relates to a distribution board equipped with a spacer for the purpose of facilitating attachment of the distribution board to the wall of a box and preventing damage during transportation.

As shown in FIGS. 1 and 2, a conventional distribution board 1 consists of a box 2 that houses distribution equipment and a frame 4 that covers the opening rim 3 of the box 2. Since there is a gap 5 between the box 2 and the frame 4, when the distribution board 1 is mounted on a wall (not shown), the frame 4 tends to shift by the gap 5, and the box 2 and the frame 4 The mounting holes (not shown) were misaligned, making installation difficult.

In addition, 6 in the figure is a door surrounded by the frame 4.

For this purpose, the first spacer 7 shown in FIG. 3 is fixed to the frame 4 by welding or the like as shown in FIG. 4, and the first spacer 7 shown in FIG. By eliminating the gap 5 by abutting or pressing the first spacer 7, the misalignment of the mounting holes between the frame 4 and the box 2 (8 in FIG. 4 is the mounting hole of the frame 4) is eliminated. .

Furthermore, when transporting this distribution board 1, if the free end 9 of the frame 4 shown in FIG. A second spacer 10 made of an elastic material as shown in FIG. 6 is attached to the opening periphery 3 of the box body 2 as shown in FIG.
1 is fitted, and the leg 1 is inserted between the box body 2 and the free end 9 of the frame body 4.
By interposing 2, the free end 9 of the frame 4 and the box 2
This prevents the contact surface from coming into contact with the product during transportation.

However, since two spacers are required, the distribution board becomes expensive.

In view of such conventional examples, the present invention is designed to achieve the above-mentioned two conventional objects using a single spacer component.

Next, the structure of the first embodiment of the present invention will be explained using FIGS. 8 to 11.

Parts that are the same as or equivalent to those in FIGS. 1 to 7 are designated by the same numbers and redundant descriptions will be omitted.

In the figure, 20 is a spacer, and the spacer 20 is the box body 2.
The locking portions 22, 22 are inserted into the through holes 21 and 21 formed in the opening periphery 3, and have a width larger than the gap 5 between the opening periphery 3 and the frame 4. A head 23 separating the end 3 and the frame 4, and a through hole 2 as shown in FIG.
When the locking parts 22, 22 are inserted into the frame 4, the legs 25 are integrally formed with a length sufficient to form a gap 24 between the free end 9 of the frame 4 and the box 2. .

Therefore, in the first embodiment of the present invention, when transporting the distribution board 1a, the spacer 20 is placed so that the legs 25 of the spacer 20 are directed toward the front of the distribution board 1a, as shown in FIG. The locking part 22.22 is inserted into the through hole 21.2 of the opening periphery 3 of the box.
1 and then lift the frame 4 with the legs 25 of the spacer 20 so that the free end 9 of the frame 4 is separated from the box 2 by the gap 24.

Also, when attaching the frame 4 to the box 2, use the spacer 2
0 to 7 with the vertical relationship reversed from the case of Figure 10.
As shown in Figure 1, connect the head 23 of the spacer 20 to the distribution board 1.
By inserting and locking the locking parts 22, 22 into the through holes 21.21 of the opening periphery 3 of the box body in the front direction of a, and compressing and inserting the head 23 into the gap 5, the box body 2. Determine the position of the frame 4 with respect to 2.

Then insert the screw from the mounting hole 8 of the frame 4 shown in Fig. 4]
, and screw it onto the box body 2.

12 to 14 are structural explanatory diagrams according to a second embodiment of the present invention. In the figures, 30 is a spacer, and the spacer 30 is a bifurcated spacer extending over the opening periphery 3 of the box body 2. head 31
leg portions 32 integrally formed with the box body 2 and having a length sufficient to form a gap 33 between the box body 2 and the free end 9 of the frame body 4;
It becomes more.

The head 31 has a thick portion that provides a desired gap between the frame 4 and the opening edge 3 of the box 2.

Therefore, in the second embodiment of the present invention, when transporting the distribution board 1a, the spacer 30 and the ends of the legs 32 of the spacer 30 are brought into contact with the box body 2 as shown in FIG. That is, the spacer 30 is placed across the opening periphery 3 of the box 2 so that the leg portion 32 is outside the opening periphery 3 of the box 2, and the free end 9 of the frame 4 is connected to the vertical length of the spacer 30. A gap 33 is formed so that the box body 2 and the box body 2 do not come into contact with each other.

Also, when attaching the frame 4 to the box 2, use the spacer 3
0 is reversed from the case of Fig. 13 (, that is, the relation of Fig. 14
As shown in the figure, the spacer 30 is placed over the opening edge 3 of the box so that the thick part of the head 31 is inside the opening edge 3 of the box, and the thick part of the head 31 is placed inside the opening edge 3 of the box. The frame body 4 is positioned between the inside of the opening edge 3 of the body and the frame body 4 to determine the position of the frame body 4 with respect to the box body 2.

Then, screws are inserted into the mounting holes 8 of the frame body 4 shown in FIG. 4 and screwed onto the box body 2.

Therefore, according to the first and second embodiments of the present invention, damage during transportation can be prevented by simply using the same spacer,
This has the advantage of being able to prevent the frame and the box from shifting when attached to a wall, thereby reducing the cost of the distribution board.
