Abstract

A cover of a portable terminal, the cover includes a conductive layer having conductive tiles formed in a region corresponding to a coil, and a protective layer disposed on a surface of the conductive layer.

First claim

What is claimed is:

1. A cover of an electronic device, the cover comprising:
a conductive layer comprising a plurality of conductive tiles spaced apart from each other such that electromagnetic waves pass through spaces between the plurality of conductive tiles, and disposed in a region corresponding to a coil; and
a protective layer disposed on a surface of the conductive layer.

2. The cover of claim 1 , wherein the protective layer comprises an insulating layer formed by anodizing the surface of the conductive layer.

3. The cover of claim 1 , wherein the conductive layer comprises graphite.

4. The cover of claim 1 , further comprising:
an insulating member disposed in the spaces.

5. The cover of claim 4 , wherein the protective layer comprises an insulating member covering another surface of the conductive layer.

6. The cover of claim 1 , wherein a shape of the conductive layer corresponds to a shape of the coil.

7. The cover of claim 6 , wherein a region of the conductive layer other than the region corresponding to the coil has a substantially rectangular shape.

8. The cover of claim 1 , further comprising a cutout part formed in a region corresponding to a winding center of the coil.

9. An electronic device comprising:
a device body;
a coil wiring connected to the device body; and
a cover disposed over a surface of the coil wiring,
wherein the cover comprises
a conductive layer comprising a plurality of conductive tiles spaced apart from each other such that electromagnetic waves pass through spaces between the plurality of conductive tiles, and disposed in a region corresponding to the coil wiring, and
a protective layer disposed on a surface of the conductive layer.

10. The electronic device of claim 9 , wherein the protective layer comprises an insulating layer formed by anodizing another surface of the conductive layer.

11. The electronic device of claim 9 , wherein the conductive layer comprises graphite.

12. The electronic device of claim 9 , wherein the cover further comprises an insulating member disposed in the spaces.

13. The electronic device of claim 12 , wherein the protective layer comprises another insulating member covering the surface of the conductive layer.

14. The electronic device of claim 9 , wherein the protective layer comprises an insulating member disposed in the spaces and covers the surface of the conductive layer.

15. The electronic device of claim 9 , wherein a shape of the conductive layer corresponds to a shape of the coil wiring.

16. The electronic device of claim 15 , wherein the tiles have an arc shape and are arranged concentrically around a central axis of the coil wiring.

17. The electronic device of claim 9 , further comprising a portable terminal and a display, and wherein the cover further comprises a cutout part formed in a region corresponding to a winding center of the coil wiring.

18. The electronic device of claim 9 , wherein a region of the conductive layer other than the region corresponding to the coil wiring has a substantially rectangular shape.

19. An electronic device comprising:
a coil wiring; and
a cover disposed over the coil wiring,
wherein the cover comprises a conductive layer comprising
an insulating layer disposed on a first surface of the conductive layer,
protrusions extending from the insulating layer,
grooves disposed between the protrusions and extending from first surface of the conductive layer to a second surface of the conductive layer, opposite the first surface, and
an insulating material disposed in the grooves,

wherein the conductive layer is configured to prevent a current from flowing between the protrusions.

20. The electronic device of claim 19 , wherein the protrusions are arranged concentrically around a central axis of the coil wiring.
