Abstract

A support device for a printed circuit board includes a plate body and a shielding cover formed integrally with the plate body, the plate body is provided with an opening and a mounting structure for mounting a printed circuit board, the shielding cover is formed from an extension of a side wall of the opening and covers the printed circuit board.

First claim

What is claimed is:

1. A support device for a printed circuit board, comprising a plate body and a shielding cover formed integrally with the plate body, wherein, the plate body is provided with an opening and a mounting structure for mounting the printed circuit board, and the shielding cover is formed from an extension of a side wall of the opening and covers the printed circuit board; and
wherein the shielding cover comprises a top plate and at least one side plate, a bottom edge of the side plate is connected to the plate body, and a top edge of the side plate is connected to the top plate.

2. The support device according to claim 1 , wherein a thickness of the top plate ranges from 2 mm to 3 mm.

3. The support device according to claim 2 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

4. The support device according to claim 1 , wherein a minimum distance between the top plate and an electronic element provided on the printed circuit board is at least 0.2 mm.

5. The support device according to claim 4 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

6. The support device according to claim 1 , wherein the mounting structure comprises a riveting seat and a riveting stud inserted in the riveting seat, and the printed circuit board is mounted to the plate body by means of the riveting seat and the riveting stud.

7. The support device according to claim 6 , wherein the shielding cover comprises one side plate, which is located between two riveting seats, and a length of the side plate in a direction from one riveting seat to the other riveting seat is less than a spacing between the two riveting seats.

8. The support device according to claim 7 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

9. The support device according to claim 6 , wherein the shielding cover comprises two side plates, which are arranged in parallel with each other, and two riveting seats are provided between the two side plates.

10. The support device according to claim 9 , wherein notches are respectively provided in the two side plates at positions corresponding to the two riveting seats, and mounting lugs corresponding to the respective notches are provided on the plate body, the mounting lugs being associated with the notches.

11. The support device according to claim 10 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

12. The support device according to claim 9 , wherein mounting holes are provided in the top plate at positions corresponding to the two riveting seats respectively.

13. The support device according to claim 12 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

14. The support device according to claim 9 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

15. The support device according to claim 6 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

16. The support device according to claim 1 , wherein the shielding cover is of a hood-shaped structure formed by punching the plate body.

17. The support device according to claim 1 , wherein the plate body and the shielding cover each forms a structure made from aluminum.

18. The support device according to claim 1 , wherein the plate body is a back plate for supporting a printed circuit board of a liquid crystal display device.
