Description of the Related Art Conventionally, when an electronic device such as a portable wireless device has two printed boards, when it becomes necessary to strengthen the ground between the two printed boards, as shown in FIG. Shield plate 11 attached to one printed circuit board 3
The leaf spring 11A is extended from the
In contact with the ground pattern. Further, as shown in FIG. 3, the ground is strengthened by setting pins 12 between the respective ground patterns of the printed boards 3 and 4 and fixing them by soldering. [0004] However, in the conventional ground reinforcement using a leaf spring, there are many problems that the contact of the leaf spring moves to generate gas noise because it is not stable. An object of the present invention is to provide a ground terminal mounting structure for an electronic device which solves the above-mentioned conventional problems. According to a first aspect of the present invention, there is provided a ground terminal mounting structure for an electronic device, comprising: a plurality of pre- printed terminals having a predetermined interval within the electronic device;
Arrange the ground terminal between the edges of the
Round terminals are elongated in the width direction of one printed circuit board
Has a lower edge that contacts the formed ground pattern
Formed on both sides of the sheet metal part and the other printed circuit board in the width direction.
Mounting part to make contact with the ground pattern
, Two attachments extending further outward from both ends of the lower edge
And two printed circuit boards are connected to the ground terminal.
The lower edge and the two mounting parts secure the printed circuit board in the width direction.
Characterized by being configured to so that is constant. FIG. 1 shows an embodiment of a ground terminal mounting structure for an electronic device according to the present invention, wherein (A) is an exploded perspective view, and (B) is a cross-sectional view after mounting. . In FIG. 1, reference numeral 1 denotes a ground terminal, which includes a sheet metal part 1A and mounting parts 1B formed at both ends of the sheet metal part 1A. The sheet metal portion 1A is bent at both ends, a cutout portion 1b is formed at a lower portion of the bent portion, and a mounting portion 1B is formed at an upper portion. Reference numeral 2 denotes a case of an electronic device, and a screw hole 2B
Are formed integrally with the connecting rib 2A formed with the connecting rib 2A and the connecting portion 2C connected to the thin wall portion 2D. Reference numeral 3 denotes a printed circuit board having a ground pattern 3A formed linearly near the edge thereof. Reference numeral 4 denotes a printed circuit board having a ground pattern 4A on both front and back sides and a cutout 4B at the corner. Reference numeral 5 denotes a chassis of the electronic device, in which a screw hole 5A is formed. Reference numeral 6 denotes a screw, and reference numeral 7 denotes a rubber key top that comes into contact with the key switch pattern of the printed circuit board 3. At the time of assembling, the key top 7 and the printed circuit board 3 are positioned on the bottom of the case 2, and then the ground terminal 1 is arranged with its notch 1b straddling the connecting portion 2C. Is brought into contact with the ground pattern 3A of the printed circuit board 3. Next, the cutout portion 4B of the printed circuit board 4 is positioned and placed on the mounting portion 1B of the ground terminal 1, and is brought into contact with the ground pattern. Further, the chassis 5 is placed on the printed circuit board 4, and the screws 6 are screw holes 5A, notches 4B, and screw holes 1C.
It is inserted into the screw hole 2B and fixed with screws. Thus, the two printed circuit boards 3 and 4
The ground pattern 3A and 4A of each printed circuit board are connected via the ground terminal 1 by screwing the ground terminal 1 between them, so that the ground of the two printed circuit boards 3 and 4 is stabilized. be able to. Further, the printed board 3 may be warped because the waterproof ribs on the entire periphery of the key top 7 are pressed by the printed board 3, but the printed board 3 may be warped by the lower edge 1 a of the ground terminal 1.
Pressing the surface prevents warpage and prevents printed circuit board 3
The structure can hold the original position of the. The ground terminal 1 is a screw 6 (for fixing the case and the chassis).
It is very close to the building, is space efficient, requires no tools, and can enhance the ground. According to the ground terminal mounting structure of the present invention, it is possible to stably strengthen the ground between the printed boards and to prevent warpage of the printed boards.
