記安全性、作業性が大幅に向上出来る。Next, the ground metal plate mounting structure of the present invention having the above-mentioned structure will be described. In the present invention, as shown in FIG. 2, the ground metal plate 4 has a shape in which the tip 4a does not protrude from the edge 1a of the box body 1, and the printed circuit board 3 of FIG. From the cross-sectional view in this state, the ground metal plate 4 soldered to the printed circuit board 3
One piece 4b is pressed by the bent portion 2a of the metal cover 2 to rotate clockwise around the edge 3a of the printed circuit board 3, and the tip 4a of the ground metal plate 4 is pushed to the inner side 2b of the metal cover 2. When pressed, the ground metal plate 4 and the metal cover 2 become electrically conductive, and the printed circuit board 3 and the metal cover 2 are electrically connected.
Can be electrically connected to. Although electrical conduction is possible by contact between the bent portion 2a of the metal cover 2 and one piece 4b of the ground metal plate 4, the surface design of the metal cover 2 often has an insulating resin. , Incomplete electrical conduction is likely to occur. The present invention provides complete electrical continuity. In the conventional structure, as shown in FIG. 4, the tip 5a of the ground metal plate 5 is projected from the edge 1a of the box 1. As described above, in the conventional structure, since the tip 5a of the ground metal plate 5 projects from the edge 1a of the box body 1, the tip 5a of the ground metal plate 5 is easy to touch and there is a safety problem. When turning the inside out, the tip 5 of the ground metal plate 5
There was a problem in workability because a touched the stand. However, according to the ground metal plate mounting structure of the present invention, the ground metal plate 4
Since the front end 4a of the box is located lower than the edge 1a of the box body 1, the safety and workability can be greatly improved.
