Abstract

A mounting structure for circuit boards in an electronic device is provided. The mounting structure includes a housing, a first circuit board, a second circuit board, and an electrical connector. The housing houses parts. The first circuit board is fixed to the housing. The second circuit board is overlapped in at least a portion with the first circuit board and is fixed to the housing. The electrical connector is configured to electronically connect the first circuit board and the second circuit board.

Claims

1. A mounting structure for circuit boards in an electronic device, the mounting structure comprising:

a housing;

a first circuit board fixed to the housing;

a second circuit board overlapped with at least a portion with the first circuit board and fixed to the housing; and

an electrical connector configured to electronically connect the first circuit board and the second circuit board.

2. The mounting structure of claim 1, wherein a void space is present between the housing and the first circuit board, and wherein the at least portion of the second circuit board is disposed in the void space.

3. The mounting structure of claim 1, wherein the housing includes a window, wherein the first circuit board includes a display panel mounted on the first circuit board and configured to display an image, and wherein the display panel of the first circuit board is attached to the window of the housing.

4. The mounting structure of claim 3, wherein the at least portion of the second circuit board is disposed in a space that the display panel does not occupy between the housing and the first circuit board.

5. The mounting structure of claim 3, wherein the housing includes a button indicator part, wherein the first circuit board includes circuitry configured to perform a function according to a touch induced in the second circuit board, wherein the second circuit board includes a module configured to receive the touch, and wherein the module comprises:

an opening not covering the button indicator part of the housing;

an electrode surface constructed around the opening;

a Printed Circuit Board (PCB) or Flexible PCB (FPCB) including a circuit connected to the electrode surface; and

a light guide film extended to forward light of a light source constructed in the first circuit board or second circuit board, to the opening.

6. The mounting structure of claim 5, wherein the first circuit board or second circuit board includes a mounted touch sensor configured to sense the touch through the electrode surface.

7. The mounting structure of claim 5, wherein the light guide film fills the opening.

8. The mounting structure of claim 5, wherein the light guide film is not disposed between the first circuit board and the second circuit board.

9. The mounting structure of claim 5, wherein the light guide film is fitted at one portion into the opening and is disposed horizontally, instead of being laminated with the PCB or FPCB.

10. The mounting structure of claim 9, wherein the opening is opened in at least one side and wherein an opened portion of the opening has a bottleneck shape.

11. The mounting structure of claim 1, wherein the first circuit board and the second circuit board are not in contact with each other.

12. The mounting structure of claim 1, wherein the electrical connector comprises at least one of an FPCB, a cable, or a wire.

13. An electronic device comprising:

a housing including a window and a button indicator part;

a main board attached to the window of the housing and including a display panel mounted on the main board, the display panel configured to display an image;

a sub board attached to the button indicator part of the housing and including a module configured to receive a touch; and

an electrical connector configured to electrically connect the main board and the sub board,

wherein at least a portion of the sub board is disposed in a space that the display panel does not occupy between the housing and the main board.

14. The electronic device of claim 13, wherein the module comprises:

an opening not covering the button indicator part of the housing;

an electrode surface constructed around the opening;

a Printed Circuit Board (PCB) or Flexible PCB (FPCB) including a circuit connected to the electrode surface; and

a light guide film extended to forward light of a light source constructed in the first circuit board or second circuit board, to the opening.

15. The electronic device of claim 14, wherein the first circuit board or second circuit board includes a mounted touch sensor configured to sense the touch through the electrode surface.

16. The electronic device of claim 14, wherein the light guide film fills the opening.

17. The electronic device of claim 14, wherein the light guide film is not disposed between the first circuit board and the second circuit board.

18. The electronic device of claim 14, wherein the light guide film is fitted at one portion into the opening and is disposed horizontally, instead of being laminated with the PCB or FPCB.

19. The electronic device of claim 18, wherein the opening is opened in at least one side and wherein an opened portion of the opening has a bottleneck shape.

20. The electronic device of claim 13, wherein the first circuit board and the second circuit board are not in contact with each other.

21. The electronic device of claim 13, wherein the electrical connector comprises at least one of an FPCB, a cable, or a wire.
