Abstract

According to certain embodiments, an electronic device comprises: a housing including a first support member; a cover member coupled with and facing the first support member; a second support member coupled with and facing the first support member; a printed circuit board assembly disposed to face the first support member, the printed circuit board assembly having a part disposed between the first support member and the cover member and another part disposed between the first support member and the second support member; wherein the printed circuit board assembly comprises: a first circuit board including a first part disposed between the first support member and the cover member, and a second part disposed between the first support member and the second support member; a second circuit board disposed to at least partially face the first part and disposed between the first circuit board and the cover member; and an interposer board disposed to correspond to at least a part of an edge of the second circuit board and coupling the second circuit board with the first circuit board, and wherein the second support member biases a part of the edge of the second circuit board.

First claim

1 . An electronic device comprising:
a housing including a first support member; a cover member coupled with and facing the first support member; a second support member coupled with and facing the first support member; a printed circuit board assembly disposed to face the first support member, the printed circuit board assembly having a part disposed between the first support member and the cover member and another part disposed between the first support member and the second support member; wherein the printed circuit board assembly comprises:
a first circuit board including a first part disposed between the first support member and the cover member, and a second part disposed between the first support member and the second support member;
a second circuit board disposed to at least partially face the first part and disposed between the first circuit board and the cover member; and
an interposer board disposed to correspond to at least a part of an edge of the second circuit board and coupling the second circuit board with the first circuit board, and
wherein the second support member biases a part of the edge of the second circuit board.

2 . The electronic device of claim 1 , wherein the second support member is configured to bias the second circuit board in an area overlapping a part of the interposer board.

3 . The electronic device of claim 1 , wherein the cover member is configured to bias another part of the edge of the second circuit board at an edge of the printed circuit board assembly.

4 . The electronic device of claim 3 , wherein the cover member is configured to bias the second circuit board in an area overlapping another part of the interposer board.

5 . The electronic device of claim 1 , further comprising a first electrical or electronic component mounted on the first circuit board in the second part,
wherein the second support member is spaced apart from the first electrical or electronic component.

6 . The electronic device of claim 1 , wherein the cover member further includes an extension piece extending toward the first support member and located at a center of the printed circuit board assembly, and
wherein an end of the extension piece is interposed between the second circuit board and the second support member and with the second support member biases a part of the edge of the second circuit board.

7 . The electronic device of claim 1 , further comprising a display attached to an inner surface of a front plate,
wherein the housing further includes the front plate facing forward, and a rear plate disposed facing an opposite direction of the front plate, and wherein the first support member is disposed in a space between the front plate and the rear plate, and the printed circuit board assembly is disposed in a space between the display and the first support member.

8 . The electronic device of claim 1 , wherein the housing further includes a front plate disposed to face forward and a rear plate disposed to face an opposite direction of the front plate, and
wherein the first support member is disposed in a space between the front plate and the rear plate, and the printed circuit board assembly is disposed in a space between the front plate and the first support member or a space between the rear plate and the first support member.

9 . The electronic device of claim 1 , wherein the second support member is configured to bias a part of an edge of the first circuit board in the second part.

10 . The electronic device of claim 1 , further comprising:
a plurality of first fastening pieces extending from an edge of the cover member; a plurality of second fastening pieces extending from the edge of the second support member; and a plurality of fastening members, wherein at least one of the first fastening pieces overlaps with one of the second fastening pieces, and wherein one of the fastening members penetrates through the first fastening piece and the second fastening piece that overlap with each other and is fastened with the first support member.

11 . The electronic device of claim 10 , wherein the second support member comprises a biasing portion at an edge, wherein the biasing portions is bent toward the first support member,
wherein each of at least a pair of second fastening pieces overlaps with one of the first fastening pieces, and wherein the biasing portion is configured to bias the second circuit board between the second fastening pieces overlapping with the first fastening pieces.

12 . The electronic device of claim 1 , further comprising a plurality of electrical or electronic components arranged on the second circuit board,
wherein the cover member contacts at least one of the electrical or electronic components.

13 . The electronic device of claim 12 , wherein the at least one electrical or electronic component contacting the cover member is disposed to overlap with at least a part of an area corresponding to the interposer board.

14 . An electronic device comprising:
a housing including a first support member; a first circuit board facing the first support member; a second circuit board facing the first support member, with a first part of the first circuit board therebetween; an interposer board corresponding to at least a part of an edge of the second circuit board and coupling the second circuit board with the first circuit board; a cover member coupled with the first support member to face the first support member, with the first part of the first circuit board or the second circuit board therebetween; and a second support member coupled with and facing the first support member, with a second part of the first circuit board therebetween, wherein the cover member biases a part of an edge of the second circuit board toward the first circuit board, and wherein the second support member is biases the first circuit board toward the first support member in the second part, and biases another part of the edge of the second circuit board toward the first circuit board.

15 . The electronic device of claim 14 , further comprising:
a plurality of first fastening pieces extending from an edge of the cover member; a plurality of second fastening pieces extending from the edge of the second support member; and a plurality of fastening members, wherein at least one of the first fastening pieces is overlaps with one of the second fastening pieces, and wherein one of the fastening members penetrates through the first fastening piece and the second fastening piece that overlap with each other and is fastened with the first support member.

16 . The electronic device of claim 15 , further wherein the second support member comprises a biasing portion at an edge of the second support member bent toward the first support member,
