Abstract

A fixing structure includes a first case whereon a first boss is disposed, a circuit board whereon a hole is disposed in a position corresponding to the first boss, a fixing component for screwing in the first boss of the first case so as to fix the circuit board above the first case, a first elastic component disposed on a first side of the circuit board for supporting the circuit board above the first case, and a second elastic component disposed on a second side opposite to the first side of the circuit board for clamping the circuit board with the first elastic component.

Claims

1. A fixing structure comprising:

a first case whereon a first boss is disposed;

a circuit board whereon a hole is disposed in a position corresponding to the first boss;

a fixing component for screwing in the first boss of the first case so as to fix the circuit board above the first case;

a first elastic component disposed on a first side of the circuit board for supporting the circuit board above the first case; and

a second elastic component disposed on a second side opposite to the first side of the circuit board for clamping the circuit board with the first elastic component.

2. The fixing structure of claim 1 wherein the fixing component is a screw.

3. The fixing structure of claim 1 wherein the first elastic component is connected to the first boss.

4. The fixing structure of claim 3 wherein the second elastic component is connected to the fixing component.

5. The fixing structure of claim 1 wherein the second elastic component is connected to the fixing component.

6. The fixing structure of claim 1 wherein the first elastic component and the second elastic component are connected integrally.

7. The fixing structure of claim 6 wherein the first elastic component and the second elastic component are formed as a washer for sheathing the fixing component.

8. The fixing structure of claim 6 wherein the first elastic component and the second elastic component are connected to the circuit board.

9. The fixing structure of claim 6 further comprising a rigid washer disposed inside the first elastic component and the second elastic component for sheathing the fixing component.

10. The fixing structure of claim 9 wherein the rigid washer is made of plastic material or metal material.

11. The fixing structure of claim 1 further comprising a second case whereon a second boss is disposed, and the fixing component passing through the first boss of the first case and the second boss of the second case so as to fix the circuit board between the first case and the second case.

12. The fixing structure of claim 11 wherein the first elastic component is connected to the first boss.

13. The fixing structure of claim 11 wherein the second elastic component is connected to the second boss.

14. The fixing structure of claim 1 wherein the first elastic component is made of rubber.

15. The fixing structure of claim 1 wherein the first elastic component is a spring.

16. The fixing structure of claim 1 wherein the first elastic component is made of conductive material.

17. The fixing structure of claim 1 wherein the second elastic component is made of rubber.

18. The fixing structure of claim 1 wherein the second elastic component is a spring.

19. The fixing structure of claim 1 wherein the second elastic component is made of conductive material.

20. The fixing structure of claim 1 wherein the circuit board is a motherboard.
