Abstract

An electronic device according to various embodiments may include: a first frame at least partially exposed to an outside of the electronic device and comprising a metal material, a flexible printed circuit board at least a portion of which is disposed adjacent to the first frame, a first connector electrically connecting the flexible printed circuit board and a main board of the electronic device, a bendable second connector electrically connecting the flexible printed circuit board and the first frame, a bolt including a bolt body extending through a groove formed in the second connector to be bolt-coupled to a bolt groove formed in the first frame and a bolt head formed integrally with the bolt body and disposed in a first direction with respect to the first frame, a plate disposed adjacent to the bolt head of the bolt and coupled to the first frame in the first direction to allow the bolt body of the bolt to be maintained in a state of being coupled to the bolt groove formed in the first frame, and an integrated circuit disposed on the flexible printed circuit board.

First claim

What is claimed is:

1. An electronic device comprising:
a first frame at least partially exposed to an outside of the electronic device and comprising a metal material;
a flexible printed circuit board, at least a portion of which is disposed adjacent to the first frame;
a first connector electrically connecting the flexible printed circuit board and a main board of the electronic device;
a bendable second connector electrically connecting the flexible printed circuit board and the first frame;
a bolt comprising a bolt body extending through a groove formed in the second connector to be bolt-coupled to a bolt groove formed in the first frame and a bolt head formed integrally with the bolt body and disposed in a first direction with respect to the first frame;
a plate disposed adjacent to the bolt head of the bolt and coupled to the first frame in the first direction to allow the bolt body of the bolt to be maintained in a state of being coupled to the bolt groove formed in the first frame; and
an integrated circuit disposed on the flexible printed circuit board.

2. The electronic device of claim 1 , wherein a distance between the bolt head of the bolt and the plate is in a range of at least 0.1 μm and a pitch corresponding to an interval of a screw line provided on the bolt body of the bolt.

3. The electronic device of claim 1 , wherein a distance between the bolt head of the bolt and the plate is in a range of at least 0.1 μm and twice a pitch corresponding to an interval of a screw line provided on the bolt body of the bolt.

4. The electronic device of claim 1 , wherein the plate includes an outer plate at least a portion of which is exposed to the outside of the electronic device.

5. The electronic device of claim 1 , wherein the plate includes an inner plate disposed in the electronic device.

6. The electronic device of claim 1 , further comprising:
a second frame disposed in the electronic device; and
a bendable third connector electrically connecting the flexible printed circuit board and the first frame.

7. The electronic device of claim 6 , wherein at least a portion of the flexible printed circuit board is supported by the second frame.

8. The electronic device of claim 1 , wherein the flexible printed circuit board is formed in a shape in which the flexible printed circuit board can be disposed in the space between the main board and the first frame.

9. The electronic device of claim 1 , wherein the flexible printed circuit board comprises a first area in which the first connector and the second connector are positioned, and at least one second area branched and extending from the first area, and
the at least one second area of the flexible printed circuit board comprising an additional antenna configured to transmit and/or receive an RF signal.

10. The electronic device of claim 1 , wherein the flexible printed circuit board comprises at least one additional antenna comprising a conductive material and electrically connected to the flexible printed circuit board configured to transmit and/or receive an RF signal.

11. The electronic device of claim 1 , wherein the first frame is segmented into a plurality of areas comprising a first area and a second area separated by an insulating material disposed between the first area and the second area.

12. The electronic device of claim 11 , wherein the electronic device comprises a plurality of second connectors,
at least one of the plurality of second connectors electrically connecting the first area of the first frame and the flexible printed circuit board, and
at least one of the plurality of second connectors electrically connecting the second area of the first frame and the flexible printed circuit board.

13. The electronic device of claim 1 , wherein the flexible printed circuit board comprises a plurality of layers,
a signal line configured to transmit an RF signal disposed on at least one of the plurality of layers, and
a ground via extending through the plurality of layers disposed around the signal line.

14. The electronic device of claim 1 , wherein the integrated circuit comprises a matching circuit configured to provide impedance matching, and
the matching circuit is disposed at a part adjacent to the part in which the second connector and the flexible printed circuit board are connected to each other.
