Abstract

An electronic device includes: a housing; a substrate disposed in the housing; an antenna radiator; and an electrical connection member electrically interconnecting the antenna radiator and the substrate, wherein the electrical connection member includes: a plate portion including a first surface facing the antenna radiator and a second surface facing away from the first surface; a first fixing portion provided at a first end of the plate portion, the first fixing portion including a through hole and a tension structure; and a second fixing portion provided at a second end of the plate portion and electrically connecting the electrical connection member to the substrate, wherein the first fixing portion is fixed to the antenna radiator via a locking device that passes through the through hole, and wherein the tension structure is configured to contact the antenna radiator and maintain tension between the electrical connection member and the antenna radiator during fastening of the locking device.

First claim

What is claimed is:

1. An electronic device comprising:
a housing;
a substrate disposed in the housing;
an antenna radiator; and
an electrical connection member electrically interconnecting the antenna radiator and the substrate,
wherein the electrical connection member comprises:
a plate portion comprising a first surface facing the antenna radiator and a second surface facing away from the first surface;
a first fixing portion provided at a first end of the plate portion, the first fixing portion comprising a through hole and a tension structure; and
a second fixing portion provided at a second end of the plate portion and electrically connecting the electrical connection member to the substrate,

wherein the first fixing portion is fixed to the antenna radiator via a locking device that passes through the through hole, and
wherein the tension structure is configured to contact the antenna radiator and maintain tension between the electrical connection member and the antenna radiator during fastening of the locking device.

2. The electronic device of claim 1 , wherein the tension structure comprises at least one tension rib extending from the first surface of the plate portion or the first fixing portion at a first angle.

3. The electronic device of claim 2 , wherein the at least one tension rib extends from an end of the first fixing portion.

4. The electronic device of claim 2 , wherein the first fixing portion comprises an opening spaced apart from the through hole, and wherein the at least one tension rib extends into the opening.

5. The electronic device of claim 1 , wherein the tension structure comprises at least one tension rib extending in a direction parallel to the first surface from the through hole.

6. The electronic device of claim 5 , wherein the at least one tension rib has a curved shape.

7. The electronic device of claim 6 , wherein the at least one tension rib has a curvature that is smaller than a curvature of an inner diameter of the through hole.

8. The electronic device of claim 5 , wherein the at least one tension rib protrudes beyond a plane defined by the first surface in a direction toward the antenna radiator.

9. The electronic device of claim 1 , wherein the tension structure comprises a bend in the plate portion, and the through hole is disposed between an end of the first fixing portion and the bend.

10. The electronic device of claim 1 , wherein the antenna radiator has a fastening hole in which the locking device is inserted to fix the first fixing portion to the antenna radiator,
wherein a recess is provided in an outer surface of the antenna radiator around the fastening hole, and
wherein the first fixing portion comprises a protrusion seated in the recess.

11. The electronic device of claim 10 , wherein the tension structure comprises at least one tension rib disposed on the protrusion and extending outward from the protrusion to elastically contact an inner wall of the recess.

12. The electronic device of claim 11 , wherein the at least one tension rib is disposed on the first surface and is at least partially bent in a direction in which the second surface is oriented.

13. The electronic device of claim 11 , wherein the at least one tension rib extends outward from the protrusion through an opening in the protrusion.

14. The electronic device of claim 10 , wherein the tension structure comprises a conductive contact disposed on the plate portion or the first fixing portion, and configured to continuously provide a contact force to an inner wall of the recess.

15. The electronic device of claim 1 , wherein the antenna radiator comprises a unit conductive portion provided via at least one non-conductive portion in a portion of the housing.

16. The electronic device of claim 15 , wherein the unit conductive portion forms a portion of an exterior of the electronic device.

17. The electronic device of claim 1 , further comprising a flexible substrate disposed between the electrical connection member and the substrate and electrically connected to the substrate,
wherein the second fixing portion of the electrical connection member is electrically connected to the flexible substrate.

18. The electronic device of claim 1 , wherein the first fixing portion is fastened to the antenna radiator in a direction parallel to the substrate.

19. The electronic device of claim 1 , wherein the first fixing portion is fastened to the antenna radiator in a direction perpendicular to the substrate.

20. The electronic device of claim 15 , wherein the antenna radiator is disposed in the housing.
