Abstract

An electronic device includes a case, an antenna supported by the case, a display module disposed within the case, a conductive chassis disposed within the case, the conductive chassis structurally supporting the display module, an electronics module disposed within the case such that the conductive chassis is positioned between the antenna and the electronics module, and an interconnect that electrically connects the conductive chassis and the case, the interconnect extending around the electronics module.

First claim

What is claimed is:

1. An electronic device comprising:
a case;
a display module disposed within the case;
a conductive chassis disposed within the case, the conductive chassis structurally supporting the display module;
an electronics module disposed within the case such that the conductive chassis is disposed between the display module and the electronics module;
an interconnect that electrically connects the conductive chassis and the case; and
an antenna positioned relative to the electronics module such that the conductive chassis and the interconnect shield the antenna from noise generated by the electronics module.

2. The electronic device of claim 1 , wherein the interconnect is disposed along a perimeter of the conductive chassis to surround the electronics module.

3. The electronic device of claim 1 , wherein the interconnect is discontinuous to allow air flow passing through the case to reach the electronics module.

4. The electronic device of claim 3 , wherein the interconnect comprises a plurality of spaced apart contacts that extend from the conductive chassis and/or the case.

5. The electronic device of claim 4 , wherein each contact comprises a spring oriented to convert a vertical force imposed upon the display module into a lateral force.

6. The electronic device of claim 4 , wherein each contact comprises a respective strip.

7. The electronic device of claim 6 , wherein the strips along a first wall of the interconnect are oriented in parallel with a plane of the first wall, and wherein the strips along a second wall of the interconnect are oriented orthogonally to a plane of the second wall.

8. The electronic device of claim 3 , wherein each contact comprises a resilient wedge configured to slidably engage a further contact of the plurality of spaced apart contacts.

9. The electronic device of claim 8 , wherein the resilient wedge has an aperture oriented to allow the air flow passing through the case to reach the electronics module.

10. The electronic device of claim 1 , wherein:
the display module comprises a frame and a plurality of display components supported by the frame; and
the frame is disposed within, and supported by, the conductive chassis.

11. An electronic device comprising:
a case;
a display module disposed within the case;
a conductive chassis disposed within the case, the conductive chassis structurally supporting the display module;
an electronics module disposed within the case such that the conductive chassis is disposed between the display module and the electronics module;
an interconnect that electrically connects the conductive chassis and the case, the interconnect comprising a plurality of spaced apart contacts configured and oriented to convert a vertical force imparted on the display module into a lateral force; and
an antenna positioned relative to the electronics module such that the conductive chassis and the interconnect shield the antenna from noise generated by the electronics module.

12. The electronic device of claim 11 , wherein the interconnect is discontinuous to allow air flow passing through the case to reach the electronics module.

13. The electronic device of claim 11 , wherein the plurality of spaced apart contacts extend from the conductive chassis and/or a conductive component of the case.

14. The electronic device of claim 11 , wherein each contact comprises a spring oriented to convert the vertical force imposed upon the display module into the lateral force.

15. The electronic device of claim 11 , wherein each contact comprises a respective strip.

16. An electronic device comprising:
a case comprising a conductive component disposed along a rear side of the case;
a display module disposed within the case;
a conductive chassis disposed within the case, the conductive chassis structurally supporting the display module;
an electronics module disposed within the case such that the conductive chassis is positioned between the display module and the electronics module; and
an interconnect that electrically connects the conductive chassis and the conductive component of the case; and
an antenna positioned relative to the electronics module such that the conductive chassis and the interconnect shield the antenna from noise generated by the electronics module.

17. The electronic device of claim 16 , wherein the conductive component is disposed along a rear side of the case.

18. The electronic device of claim 16 , wherein:
the display module comprises a frame and a plurality of display components supported by the frame; and
the frame is disposed within, and supported by, the conductive chassis.

19. The electronic device of claim 16 , wherein:
the case comprises a sidewall;
the conductive chassis comprises a sidewall disposed inward of, and extending along, the sidewall of the case; and
the antenna is mounted on the sidewall of the case outward of the sidewall of the conductive chassis.

20. The electronic device of claim 16 , wherein the interconnect comprises a plurality of spaced apart contacts that extend from the conductive chassis and/or the case.
