Sliding expansion data card

1. A sliding expansion data card, comprising:

a main bearing plate;

a data card interface;

a shield located on a lower surface of the main bearing plate;

a spring plate, one end of the spring plate being set on the shield, wherein, when the data card interface is connected with an external device, an opposite end of the spring plate contacts the data card interface; and

a data card interface connector bearing plate and a sliding soft plate, wherein one end of the data card interface connector bearing plate is connected with the sliding soft plate and an opposite end is configured to fix the data card interface.

2. The sliding expansion data card of claim 1 , wherein the shield is located on the lower surface of the main bearing plate adjacent the data card interface.

3. The sliding expansion data card of claim 2 , wherein the one end of the spring plate is fixed beside the shield.

4. The sliding expansion data card of claim 1 , further comprising a tongue set on the opposite end of the spring plate.

5. The sliding expansion data card of claim 4 , wherein when the data card interface is connected with the external device, the tongue contacts the data card interface.

6. The sliding expansion data card of claim 4 , wherein the spring plate has a width that is not greater than a width of the data card interface.

7. The sliding expansion data card of claim 6 , wherein the spring plate has a thickness that is not greater than a thickness of the shield.

8. The sliding expansion data card of claim 6 , wherein the width of the tongue is between 0.2 mm to 0.3 mm.

9. The sliding expansion data card of claim 1 , wherein the data card interface connector bearing plate is moved to drive the data card interface to slide on the main bearing plate.

10. The sliding expansion data card of claim 1 , wherein the sliding soft plate comprises a flexible printed circuit.

11. The sliding expansion data card of claim 1 , wherein the data card interface is a universal serial bus (USB) interface.

12. A sliding expansion data card, comprising:

a main bearing plate;

a data card interface;

a shield located on a lower surface of the main bearing plate;

a spring plate, one end of the spring plate being set on the shield, wherein, when the data card interface is connected with an external device, an opposite end of the spring plate contacts the data card interface; and

a data card interface connector bearing plate and a sliding soft plate, wherein the data card interface connector bearing plate is configured to fix the data card interface, wherein the data card interface connector bearing plate is connected with one end of the sliding soft plate and another end of the sliding soft plate is connected with the main bearing plate, and wherein the data card interface connector bearing plate is moved to push the data card interface to slide on the main bearing plate.

13. The sliding expansion data card of claim 12 , wherein the shield is located on the lower surface of the main bearing plate adjacent the data card interface.

14. The sliding expansion data card of claim 13 , wherein the one end of the spring plate is fixed beside the shield.

15. The sliding expansion data card of claim 12 , further comprising a tongue set on the opposite end of the spring plate.

16. The sliding expansion data card of claim 15 , wherein when the data card interface is connected with the external device, the tongue contacts the data card interface.

17. The sliding expansion data card of claim 15 , wherein the spring plate has a width that is not greater than a width of the data card interface.

18. The sliding expansion data card of claim 17 , wherein the spring plate has a thickness that is not greater than a thickness of the shield.

19. The sliding expansion data card of claim 17 , wherein the width of the tongue is between 0.2 mm to 0.3 mm.

20. The sliding expansion data card of claim 12 , wherein the sliding soft plate comprises a flexible printed circuit.
