Abstract

Disclosed is an electronic device that includes a housing; a printed circuit board disposed within the housing; a communication circuit disposed on the printed circuit board; at least one exterior metal frame forming at least a part of the housing, and is electrically connected with the communication circuit; a first electric path that electrically connecting the at least one exterior metal frame and the printed circuit board with each other; a support structure including a metal region and a non-metal region, and supporting the printed circuit board and/or the at least one exterior metal frame; and a second electric path disposed between the printed circuit board and the metal region of the support structure and is electrically connected with the first electric path.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a printed circuit board disposed within the housing;
a communication circuit disposed on the printed circuit board;
one or more high speed data processing units disposed on the printed circuit board;
at least one exterior metal frame forming at least a part of the housing, and is electrically connected with the communication circuit;
a first electric path electrically connecting the at least one exterior metal frame and the PCB with each other;
a support structure including a metal region and a non-metal region, and supporting the printed circuit board and/or the at least one exterior metal frame; and
a second electric path disposed between the printed circuit board and the metal region of the support structure and is electrically connected with the first electric path,
wherein the first electric path and the second electric path are configured to prevent static electricity, which is generated on the at least one exterior metal frame, from flowing to the one or more high speed data processing units.

2. The electronic device of claim 1 , wherein the second electric path is disposed between a first surface of the printed circuit board and a first region of the metal region of the support structure facing the first region of the printed circuit board.

3. The electronic device of claim 2 , wherein the second electric path comprises a conductor or a clip-type connection terminal.

4. The electronic device of claim 1 , wherein the first electric path is configured in a form of a clip.

5. The electronic device of claim 1 , wherein the metal region is spaced apart from one surface of the printed circuit board in a vertical direction.

6. The electronic device of claim 1 , wherein, when static electricity is generated on the at least one exterior metal frame, the generated static electricity is discharged to the metal region of the support structure through the first electric path and the second electric path.

7. The electronic device of claim 1 , wherein the one or more high speed data processing units include at least one of an application processor (AP), a communication processor (CP), a sensor unit, and at least one camera.

8. The electronic device of claim 7 , wherein among the one or more high speed data processing units, the at least one camera is disposed adjacent to the first electric path.

9. The electronic device of claim 1 , wherein the at least one exterior metal frame further includes a third electric path that is disposed between a second portion, which is spaced, by a non-conductive material, apart from a first portion that is in contact with the first electric path, and the printed circuit board.

10. The electronic device of claim 9 , wherein the static electricity generated on the at least one exterior metal frame is directed toward the printed circuit board through at least one of the first electric path and the third electric path, and is discharged to the second portion of the at least one exterior metal frame by the third electric path.

11. The electronic device of claim 10 , wherein the second portion of the at least one exterior metal frame includes one of a metallic rear case, a metallic back cover, and a metallic component case.

12. The electronic device of claim 1 , wherein the at least one exterior metal frame includes a plurality of portions that are spaced apart from each other by a non-conductive material to operate as antenna radiators.

13. The electronic device of claim 12 , wherein the at least one exterior metal frame includes an upper end exterior metal frame and a lower end exterior metal frame which are positioned on upper and lower ends of the electronic device, respectively.

14. An electronic device comprising:
a printed circuit board located within the electronic device;
one or more high speed data processing units disposed on the printed circuit board;
a first segmented antenna radiator forming at least a part of an exterior of the electronic device;
a first contact electrically connecting the first segmented antenna radiator and the printed circuit board with each other;
a support structure including a metal region and a non-metal region, and which supports the printed circuit board and/or the first segmented antenna radiator; and
a second contact disposed between the printed circuit board and the metal region and is electrically connected with the first contact,
wherein the first contact and the second contact are configured to prevent the static electricity, which is generated on the first segmented antenna radiator, from flowing to the one or more high speed data processing units.

15. The electronic device of claim 14 , wherein the support structure includes a second segmented antenna radiator.

16. The electronic device of claim 15 , wherein each of the first and second segmented antenna radiators includes an outer peripheral metal frame of the electronic device.

17. The electronic device of claim 15 , wherein the second segmented antenna radiator includes one of a metallic rear case, a metallic back cover, and a metallic component case.

18. The electronic device of claim 14 , wherein, when static electricity is generated on the first segmented antenna radiator, the generated static electricity is discharged to the metal region of the support structure through the first and second contacts.

19. The electronic device of claim 18 , wherein each of the first and second contacts comprises one of a conductor or a clip-type terminal.
