Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a mounting structure for mounting an electric device on a panel.

<< Prior Art >> For example, an electric device 1 such as a power supply device shown in FIG. 3 includes a substrate 2 on which a resistor and a capacitor are mounted and which is supported by a support plate 3. The support plate 3 is composed of a horizontal piece 4 (a plane parallel to the substrate 2. The same applies hereinafter) and a vertical piece 5 bent substantially at a right angle to the horizontal piece 4, and at both end portions of the pieces 4 and 5, Panel mounting holes 6, 7 and 8, 9 are formed, one of which is a round hole and the other of which is a cutout hole.

When mounting such an electric device 1 on a panel, or when mounting it on a horizontal panel 10 as shown, a vertical strip 5
The screws 11 and 12 which are tapping screws are inserted into the panel mounting holes 8 and 9 and fixed to the panel 10. Alternatively, with the horizontal piece 4 facing downward, the screws 11 and 12 are inserted into the panel mounting holes 6 and 7 and fixed to the panel 10.

Further, in the illustrated state, the screws 11 and 12 can be inserted into the pawl mounting holes 6 and 7 of the horizontal piece 4 to fix the electric device 1 to the side panel 13. Similarly, turn the vertical piece 5 toward the side panel 13 and screw 1 into the panel mounting holes 8 and 9.
The electric device 1 can be fixed to the side panel 13 by inserting the electric devices 1 and 12.

<< Problems to be Solved by the Invention >> However, such an electric device 1 cannot be attached to the front panel 14 due to the shape of the support plate 3. Therefore, in general, when it is desired to attach the electric device to the front panel 14, as shown in FIG. 4, another support having the flange portions 17 and 18 formed on one side of the horizontal piece 15 and the vertical piece 16 is provided. It is necessary to use the plate 19. However, with the support plate 19 having such a shape, the electrical equipment cannot be attached to the horizontal panel 10 or the side panel 13 because of the flange portions 17 and 18, and the front panel 14 is used exclusively.

Further, as another method for attaching the electric device to the front panel 14, as shown in FIG.
There is a way to use. For this, first, the mounting bracket 20 is attached to the front panel 14, and then the support plate 21 is mounted to the mounting bracket 20, and conversely, the support plate 21 is first mounted to the mounting bracket 20, and then the mounting bracket 20 is mounted.
Is attached to the front panel 14. The former is
In order to attach the support plate 21 to the metal fitting 20, it is necessary to attach the screw 22 from below, and a space for performing the attachment work is required below the metal fitting 20, which causes a problem of poor workability. In the latter, since the support plate 21 to which the electric device is attached is attached to the mounting member 20 and the mounting member 20 is attached to the front panel 14, it is necessary to support the electric device during the mounting work, and when the electric device is heavy, Has a problem that it is difficult to work.

Therefore, an object of the present invention is to provide a mounting structure for an electric device provided with a mounting bracket that can be easily and surely mounted on a front panel even if it is a support plate for mounting flat and side panels.

<< Means for Solving the Problem >> A mounting structure for an electric device according to the present invention is one in which an electric device mounted on a support plate composed of a horizontal piece and a vertical piece bent at a substantially right angle is attached to the horizontal piece and the vertical piece. A mounting structure for an electric device that is fixed to a panel with screws through panel mounting holes provided at both ends, and one end of panel mounting holes provided in a horizontal piece and a vertical piece of a support plate. A mounting bracket with a hook that locks the panel mounting hole and a projecting piece that is bent obliquely toward the panel side is previously screwed to the panel, and the electrical device is fixed to the panel through this mounting bracket. It has a structure.

<< Embodiment >> FIG. 1 shows an embodiment of the present invention. An electric device (not shown) is attached to the support plate 31. The support plate 31 is composed of a horizontal piece 32 parallel to the board of the electric device and a vertical piece 33 bent substantially at a right angle to the board. Holes 34 and 35 (only one end is shown) are formed.

On the other hand, the mounting bracket 36 is a plate member formed in an L shape along the side edge of the support plate 31, and has a front panel 3 at the top end.
The projecting piece 38 that is bent obliquely toward the 7 side, and the hook 39 that is bent and formed toward the front side on the upper right side of the L-shaped vertical portion
And another hook 40 that is also bent toward the front side on the upper right side of the horizontal portion. These hooks 3
9 and 40 are panel mounting holes 34 and 3 of the support plate 31.
5, the panel mounting holes 3
It is formed in a size into which 4, 35 can be inserted.

The mounting bracket 36 is temporarily fixed to the front panel 37 by inserting screws 43 and 44 into screw insertion holes 41 and 42 formed in the vertical and horizontal portions thereof. This temporary fixing is the second
As shown in the figure, the projecting piece 38 at the upper end is the front panel 37.
The upper part of the metal fitting 31 is held in a state of being floated from the panel 37 by lightly abutting against it. Retighten 44 and fix it permanently. As a result, the protruding piece 38 is pinched between the metal fitting 31 and the panel 37 and becomes flat.

As described above, when the mounting bracket 31 is temporarily fixed to the panel 37 and is held in a state of being slightly floated from the panel 37 by the projecting piece 38, it becomes easy to mount the supporting plate 31, that is, the electric device on the bracket 31. Further, although the projecting piece 38 is crushed at the time of the final fixing, the repulsive force due to the spring work makes it possible to perform the same firm mounting as through the spring washer.

In this invention, the position where the protrusion 38 is formed is arbitrary, and the position and shape of the hooks 39 and 40 are changed according to the position and shape of the panel mounting hole formed in the support plate of the electric device to be used. .

<Effects of the device> As described above, the mounting structure of the electric device according to the present invention is
Of the panel mounting holes provided in the horizontal piece and the vertical piece of the support plate to which the electric device is attached, a hook for locking the panel mounting hole at one end and a projecting piece obliquely bent toward the panel side Since the mounting bracket with is fixed to the panel in advance and the electrical device is fixed to the panel via this mounting bracket, the mounting bracket can be held in a state of being floated from the panel by the projecting piece. The panel mounting hole of the plate can be easily engaged with the hook of the mounting bracket, which has the effect of easily and reliably mounting the electric device on the front panel. Further, since the panel mounting holes of the support plate are provided at both side ends of the horizontal piece and the vertical piece of the support plate, the electric device can be directly attached to the flat panel or the side panel.
