[0119] Reference Fig. 9The second waterproof packaging structure 900 of the present disclosure may be disposed at one side of the connection hole 117 and may be configured to close an opening area of ​​the connection hole 117 while supporting at least a portion of the flexible PCB.

[0120] For example, the connection hole 117 may be formed at the bottom of the housing (eg Figure 2 The second bottom 120b of the embodiment of the present invention is provided. The connection hole 117 may be formed vertically through the bottom. The connection hole 117 may be formed so that in the drawings shown, the lower opening area is larger than the upper opening area. The track grooves 901a and 902a may be provided in the connection hole 117.

In the present disclosure, the surface on which the display 1250 is disposed is defined as a first surface or front surface of the electronic device 1200. The surface opposite to the front surface is defined as a second surface or rear surface of the electronic device 1200. In addition, a surface surrounding the space formed between the front surface and the rear surface is defined as a third surface or side surface of the electronic device 1200.

[0156] In one embodiment, the foldable housing 1500 may include a first housing structure 1510, a second housing structure 1520 including a sensor area 1524, a first back cover 1580 and a second back cover 1590. The foldable housing 1500 of the electronic device 1200 is not limited to Fig.12 and Figure 2 The forms and connections shown in the drawings may be realized by combinations and / or connections of other shapes or components. For example, in another embodiment, the first housing structure 1510 and the first back cover 1580 may be formed integrally with each other, and the second housing structure 1520 and the second back cover 1590 may be formed integrally with each other.

[0157] In the illustrated embodiment, the first housing structure 1510 and the second housing structure 1520 may be disposed on opposite sides of the folding axis (axis A), and may have shapes that are completely symmetrical to each other about the folding axis A. As will be described below, the angle or distance between the first housing structure 1510 and the second housing structure 1520 may vary depending on whether the electronic device 1200 is in a flat state, a folded state, or an intermediate state. In the illustrated embodiment, unlike the first housing structure 1510, the second housing structure 1520 may additionally include a sensor region 1524 in which various sensors are arranged, but may have shapes that are symmetrical to each other in other regions.

However, the arrangement, shape and size of the sensor area 1524 are not limited to the example shown. For example, in another embodiment, the sensor area 1524 may be provided in another corner of the second housing structure 1520, or provided in any area between the upper corner and the lower corner of the second housing structure 1520. In one embodiment, the components embedded in the electronic device 1200 for performing various functions may be exposed on the front surface of the electronic device 1200 through the sensor area 1524 or through one or more openings formed in the sensor area 1524. In various embodiments, the components may include various types of sensors. The sensor may include, for example, at least one of a front camera, a receiver or a proximity sensor.

[0162] The first rear cover 1580 may be provided on the rear surface of the electronic device 1200 and may be located on one side of the folding axis A. The first rear cover 1580 may have, for example, a substantially rectangular perimeter, and the perimeter may be surrounded by the first housing structure 1510. Similarly, the second rear cover 1590 may be provided on the rear surface of the electronic device 1200 and may be located on the opposite side of the folding axis A. The second rear cover 1590 may have a perimeter surrounded by the second housing structure 1520.

[0163] In the illustrated embodiment, the first back cover 1580 and the second back cover 1590 may have a shape that is substantially symmetrical about the folding axis (axis A). However, the first back cover 1580 and the second back cover 1590 do not necessarily have mutually symmetrical shapes. In another embodiment, the electronic device 1200 may include a first back cover 1580 and a second back cover 1590 having various shapes. In another embodiment, the first back cover 1580 may be formed integrally with the first housing structure 1510, and the second back cover 1590 may be formed integrally with the second housing structure 1520.
