Description

[Detailed Description of the Invention] (a) Technical Field The present invention relates to a panel mounting device for electronic equipment that electrically and mechanically connects a panel to a housing body with screws.

(b) Prior art Conventionally, in order to attach a surface-treated non-conductive panel to the housing body, conductive paint was applied to each contact area in order to ensure continuity between the panel and the housing body. , the panel and the main body of the casing were screwed together.
Alternatively, as shown in Fig. 1, attach the chrysanthemum washers 2 to the casing body 1, and screw the screws 6 into the screw holes 5 of the casing body 1 through the mounting holes 4 of the panel 3 to perform these installations. was.

(c) Disadvantages of the prior art In the prior art, there was a problem that the conductive paint was very expensive and the use of this paint led to an increase in the cost of the product. Also, the first
As shown in the figure, in order to attach the chrysanthemum washer 2 to the housing body 1, the chrysanthemum washer 2 is usually spot welded to the housing body 1, which makes the work complicated and increases the working time. Furthermore, processing costs also increased, and since the chrysanthemum washers 2 had to be used, the number of parts also increased.

(d) Purpose of the invention The present invention solves the above-mentioned drawbacks, does not use conductive paint or chrysanthemum wax, and can be done easily and inexpensively.
The present invention provides a novel panel mounting device for electronic equipment in which a panel is mounted on a housing body.

(E) Embodiment FIG. 2 is a perspective view showing an embodiment of the panel mounting device for electronic equipment according to the present invention, in which only a screw hole 5 is provided in the casing body 1. The surface-treated non-conductive panel 3 does not have a simple circular mounting hole 4 like the conventional example shown in FIG. A mounting hole 8 having a plurality of projecting pieces 7 is formed. The projecting piece 7 is formed using a simple mold so as to have a twist with respect to the vertical direction of the panel 3, so that it projects toward the side where it is attached to the housing body 1.

Therefore, as shown in FIG.
When the panel 3 and the housing body 1 are connected mechanically, the screw 6 is inserted into the screw hole 5 of the housing body 1 through the mounting hole 8, and the screw 6 is tightened and fixed. 7 is wedged into the housing body 1, so
Each painting is destroyed, panel 3 and housing body 1
conduction, and they are also electrically coupled.

(F) Effect The panel mounting device for electronic equipment according to the present invention has a plurality of protrusions on the periphery that protrude toward the mounting side of the casing body, instead of forming a circular mounting hole in the panel as in the conventional case. After forming the mounting hole with the panel and then simply tightening the screws, electrical continuity between the panel and the casing body can be ensured, and the number of work steps can be reduced. In addition, since the mounting hole with the protrusion can be easily formed using a simple mold, the processing cost is reduced.Furthermore, in addition to screws, special materials such as chrysanthemum washer or conductive paint are used to measure continuity. No parts or materials are required.
