Abstract

Claims (48)

1 . An electronic device comprising:

a hinge module;

a first housing coupled at least in part to a first side of the hinge module, the first housing including a first substrate assembly;

a second housing coupled at least in part to a second side of the hinge module, the second housing including a second substrate assembly, and the second housing formed to be folded and unfolded with respect to the first housing by using the hinge module;

a flexible display supported by upper portions of the first housing and the second housing, the flexible display configured to be folded and unfolded;

at least one flexible printed circuit board (FPCB) electrically connecting the first substrate assembly and the second substrate assembly;

a through hole formed in the first housing to form a path through which the at least one FPCB passes;

a first sealing member disposed to press a first side surface of the at least one FPCB disposed in the through hole; and

a second sealing member disposed to press a second side surface of the at least one FPCB disposed in the through hole,

wherein the first sealing member comprises at least one first coupling portion formed to protrude from one side surface,

wherein the second sealing member comprises at least one second coupling portion formed at a position corresponding to the at least one first coupling portion, and

wherein the at least one first coupling portion and the at least one second coupling portion are coupled via interference fitting.

2 . The electronic device of claim 1 , wherein the first sealing member comprises:

a body part constituting a body of the first sealing member;

an elastic part surrounding a specified portion of the body part; and

a first packing portion formed to protrude from one side surface of the elastic part.

3 . The electronic device of claim 1 , wherein a region of the through hole of the first housing where the at least one FPCB is not disposed is formed to constitute a diaphragm structure by using a first packing portion formed to protrude from the first sealing member and a second packing portion formed to protrude from the second sealing member.

4 . The electronic device of claim 1 ,

wherein the at least one FPCB is disposed above the first sealing member, and

wherein a height of the first sealing member is formed to be lower than that of the second sealing member.

5 . The electronic device of claim 2 , wherein the body part and the elastic part are made of different materials or are made of substantially the same material.

6 . The electronic device of claim 2 ,

wherein the body part is made of one of polycarbonate, polyimide, plastic, polymer, or ceramic, and

wherein the elastic part is made of one of rubber and silicone.

7 . The electronic device of claim 2 ,

wherein the second sealing member comprises a second packing portion made of one of rubber and silicone, and

wherein the second packing portion is formed to protrude from a specified position of the second sealing member at a preset interval.

8 . The electronic device of claim 7 ,

wherein the first packing portion formed on the first sealing member and the second packing portion formed on the second sealing member are disposed at different positions, and

wherein some of the first packing portion and some of the second packing portion are coupled to overlap each other.

9 . The electronic device of claim 1 ,

wherein the first sealing member and the second sealing member are coupled using the first coupling portion and the second coupling portion in a state where the at least one FPCB is kept upright in a substantially vertical direction, and

wherein the coupled first sealing member and second sealing member are slid through the at least one FPCB and are seated in the through hole of the first housing.

10 . The electronic device of claim 1 ,

wherein the first housing includes a first rear cover disposed on a first side frame, and a protection member disposed on at least a portion of an inner surface of the first rear cover,

wherein at least a portion of the first housing and at least a portion of the first rear cover are adhered by using an adhesive member, and

wherein a third sealing member is disposed between the protection member and the at least one FPCB.

11 . The electronic device of claim 4 , wherein a portion of the at least one FPCB and a portion of the first housing are coupled by using an adhesive.

12 . The electronic device of claim 1 ,

wherein a portion of an upper end of the first sealing member includes an inclined surface, and

wherein the inclined surface is formed in a manner that an inner surface of a bent portion of the at least one FPCB does not contact a portion of the upper end of the first sealing member.

13 . The electronic device of claim 1 ,

wherein a gap is included between a portion of the side surface of the first sealing member and a portion of the first housing, and

wherein the gap is formed in a manner that a portion of the first housing does not contact a portion of the first sealing member during folding and unfolding operations of the first housing and the second housing.

14 . The electronic device of claim 1 ,

wherein the first sealing member includes an elastic part formed on one side surface,

wherein at least a portion of the elastic part is coupled to at least a portion of an inner surface of the through hole formed in the first housing, and

wherein at least a portion of one side surface of the second sealing member is coupled to at least a portion of the other side surface of the at least one FPCB.
