Abstract

Connector shielding devices are described herein. One connector shielding device includes a circuit board having a connector; and a plurality of spring fingers extending from a first surface of the circuit board, the plurality of spring fingers positioned around the connector of the circuit board, wherein each spring finger of the plurality of spring fingers is configured to deflect toward the first surface of the circuit board when the connector of the circuit board is connected with a connector of an additional circuit board.

First claim

What is claimed is:

1. A device comprising:
a circuit board having a connector; and
a plurality of spring fingers, each spring finger having a first part and a second part,
wherein the first part of each spring finger of the plurality of spring fingers extends in a perpendicular direction from a first surface of the circuit board,
wherein the first parts of the plurality of spring fingers provide four walls around the connector of the circuit board when the connector of the circuit board is connected with a connector of an additional circuit board, wherein the four walls are positioned in an opening between the circuit board and the additional circuit board,
wherein the second part of each spring finger of the plurality of spring fingers is configured to deflect toward the first surface of the circuit board when the connector of the circuit board is connected with the connector of the additional circuit board, and
wherein the four walls of the plurality of spring fingers are configured to shield electrical noise generated from the connection between the circuit board and the additional circuit board.

2. The device of claim 1 , wherein the circuit board is a printed circuit board or a flexible printed circuit.

3. The device of claim 1 , further comprising:
a camera module connected to the circuit board.

4. The device of claim 1 , wherein at least one spring finger of the plurality of spring fingers comprises an aperture.

5. The device of claim 1 , wherein at least two adjacent spring fingers of the plurality of spring fingers comprise a gap between the respective two adjacent spring fingers.

6. The device of claim 1 , wherein the plurality of spring fingers is a single piece of metal.

7. The device of claim 1 , wherein the plurality of spring fingers comprises individual spring fingers separately connected to the first surface of the circuit board.

8. A device comprising:
a circuit board having a connector; and
a plurality of spring fingers extending from a base support adjacent to a first surface of the circuit board, each spring finger having a first part and a second part,
wherein the first part of each spring finger of the plurality of spring fingers extends in a perpendicular direction from the first surface of the circuit board,
wherein the first parts of the plurality of spring fingers provide four walls around the connector of the circuit board when the connector of the circuit board is connected with a connector of an additional circuit board, wherein the four walls are positioned in an opening between the circuit board and the additional circuit board,
wherein the second part of each spring finger of the plurality of spring fingers is configured to deflect toward the first surface of the circuit board when the connector of the circuit board is connected with the connector of the additional circuit board, and
wherein the four walls of the plurality of spring fingers are configured to shield electrical noise generated from the connection between the circuit board and the additional circuit board.

9. The device of claim 8 , further comprising:
a camera module connected to the circuit board.

10. The device of claim 8 , wherein at least one spring finger of the plurality of spring fingers comprises an aperture.

11. The device of claim 8 , wherein at least two adjacent spring fingers of the plurality of spring fingers comprise a gap between the respective two adjacent spring fingers.

12. The device of claim 8 , wherein the plurality of spring fingers and the base support are a single piece of metal.

13. A device comprising:
a first circuit board having a first connector;
a second circuit board having a second connector connectable with the first connector of the first circuit board; and
a plurality of spring fingers positioned between the first circuit board and the second circuit board,
wherein the plurality of spring fingers is positioned around the first connector and the second connector when the first connector and the second connector are connected,
wherein a portion of each spring finger is positioned perpendicular to a surface of the first circuit board and a surface of the second circuit board when the first connector and the second connector are connected,
wherein the first circuit board provides a first wall of a Faraday cage, the second circuit board provides a second wall of the Faraday cage, and the portions of the plurality of spring fingers provide four walls of the Faraday cage when the first connector and the second connector are connected,
wherein the four walls are positioned in an opening between the first circuit board and the second circuit board such that the four walls of the plurality of spring fingers are configured to shield electrical noise generated from the connection between the first connector and the second connector.

14. The device of claim 13 , wherein the first circuit board is a printed circuit board, and the second circuit board is a flexible printed circuit.

15. The device of claim 14 , further comprising:
a camera module connected to the second circuit board.

16. The device of claim 13 , wherein at least one spring finger of the plurality of spring fingers comprises an aperture.

17. The device of claim 13 , wherein at least two adjacent spring fingers of the plurality of spring fingers comprise a gap between the respective two adjacent spring fingers.

18. The device of claim 13 , wherein the plurality of spring fingers comprises individual spring fingers separately connected to the first circuit board or the second circuit board.

19. The device of claim 13 , wherein a retention force is provided by the connection of the first connector and the second connector,
wherein a spring force is provided in an opposite direction of the retention force by a deflection of the spring fingers between the first and second circuit boards when the first connector and the second connector are connected, and
wherein the retention force is greater than the spring force.

20. The device of claim 13 , wherein a fraction of the plurality of spring fingers is connected to and extends from a surface of the first circuit board or a base support adjacent to the surface of the first circuit board, and wherein a remaining fraction of the plurality of spring fingers is connected to and extends from a surface of the second circuit board or a base support adjacent to the surface of the second circuit board.
