Abstract

An electronic device is provided. The electronic device includes a housing, a main circuit board, a battery, a battery protection module disposed on one side surface of the battery, a protective holder that surrounds at least part of the battery protection module, and a flexible printed circuit board that extends from one side surface of the battery protection module and that is connected to the main circuit board. The flexible printed circuit board includes a first portion extending from the battery protection module in a second direction perpendicular to a first direction toward the main circuit board, a second portion extending from the first portion while being bent, a third portion extending from the second portion in a third direction opposite to the second direction, a fourth portion extending from the third portion in the first direction, and a connector connected to an end portion of the fourth portion and connected to the main circuit board.

First claim

What is claimed is:

1. A portable communication device comprising:
a housing;
a first printed circuit board (PCB) disposed in the housing and including at least one of an application processor, memory, a communication chip, or a sensor disposed thereon;
a battery disposed in the housing;
a battery protection module disposed between the first PCB and a lateral surface of the battery, the battery protection module including a second PCB including a protection integrated circuit (IC) disposed thereon and electrically connected to an inside of the battery;
a tape covering the battery protection module; and
a flexible printed circuit board (FPCB) including a first connecting portion and a second connecting portion connected to the battery protection module and the first PCB, respectively, the FPCB further including a first FPCB portion extending from the first connecting portion in a first direction parallel to the lateral surface of the battery, a second FPCB portion extending upwardly from the first FPCB portion as bent, a third FPCB portion extending from the second FPCB portion over the first FPCB portion in a second direction opposite to the first direction, and a fourth FPCB portion extending from the third FPCB portion in a third direction perpendicular to the second direction and facing toward the first PCB, the first FPCB portion being at least partially covered by the tape, and a an entire portion of the third FPCB portion extending along an outer surface of the tape and not being covered by the tape.

2. The portable communication device of claim 1 ,
wherein the housing includes a rear case, and
wherein when viewed from the rear case, the third FPCB portion is placed on top of the tape.

3. The portable communication device of claim 2 , wherein when viewed from the rear case, the fourth FPCB portion is not placed on top of the tape.

4. The portable communication device of claim 1 further comprising:
a display;
wherein when viewed from a direction in which the display is facing, the third FPCB portion is placed on bottom of the tape.

5. The portable communication device of claim 4 , wherein when viewed from a direction in which the display is facing, the fourth FPCB portion is not placed on bottom of the tape.

6. The portable communication device of claim 1 , wherein the tape covers at least part of the battery.

7. The portable communication device of claim 1 , wherein the first direction is a direction toward a first side surface of the portable communication device.

8. The portable communication device of claim 1 , wherein the second direction is a direction toward a second side surface of the portable communication device.

9. The portable communication device of claim 1 , wherein the battery includes a plurality of electrodes disposed along the third direction and connected to the battery protection module.

10. The portable communication device of claim 1 , wherein the housing includes a partition disposed between the first PCB and the battery and, wherein the fourth FPCB portion is disposed as crossing over the partition.

11. The portable communication device of claim 1 , wherein at least one of the first FPCB portion, the third FPCB portion, or the fourth FPCB portion comprises a V-shaped bending portion or a W-shaped bending portion on at least a part thereof.

12. The portable communication device of claim 1 , wherein a width of the first FPCB portion and a width of the third FPCB portion are the same.

13. The portable communication device of claim 1 , wherein a width of the fourth FPCB portion is greater than a width of the third FPCB portion.

14. The portable communication device of claim 1 , wherein a width of the second connecting portion is greater than a width of the fourth FPCB portion.

15. The portable communication device of claim 1 , wherein the third FPCB portion and the fourth FPCB portion are disposed on the same plane and are formed in an “L” shape.

16. The portable communication device of claim 1 , wherein the second FPCB portion forms a “U” shape.
