At least a portion of the printed circuit board 540 may be located in the first area 500a.

According to one embodiment, the sealing member 550 may be disposed between the plate and the printed circuit board 540. The sealing member 550 may be disposed between the plate on which the second hole 522 is formed and the printed circuit board 540 . For example, the sealing member 550 may be disposed between the first plate 510 on which the second hole 522 is formed and the printed circuit board 540. The sealing member 550 may be an adhesive member such as a double-sided tape (eg, PET double-sided tape).

According to one embodiment, the sealing member 550 may include one or more holes. The sealing member 550 is disposed along the edge of the plate and may include a third hole 551 that at least partially corresponds to the first hole 521. The key 530 may penetrate the third hole 551 of the sealing member 550. According to one embodiment, unlike FIG. 7A, the first area 500a may not include a hole corresponding to the second hole 522.

According to one embodiment, the bonding member 560 may be applied to the first area 500a of the key assembly 500. For example, the bonding member 560 may be applied inside the second hole 522 formed in the second plate 520 to adhere a portion of the printed circuit board 540 to the second plate 520. . The bonding member 560 may be formed to surround the printed circuit board 540 . The bonding member 560 may be applied to the second hole 522 formed in the second plate 520 and the internal space surrounded by the sealing member 550. The printed circuit board 540 may be fixed to the first area 500a of the key assembly 500 by the bonding member 560.

According to one embodiment, moisture may not be transmitted to the edge of the key assembly 500 in the first area 500a of the key assembly 500 by the sealing member 550. According to one embodiment, the first area 500a of the key assembly 500 may be configured to include a bonding member 560. According to one embodiment, the first area 500a of the key assembly 500 may have an ultrasonic fusion structure.

According to one embodiment, the bonding member 560 may be formed to surround the printed circuit board 540. According to one embodiment, one side of the first area 500a of the key assembly 500 facing the 3-1 direction (+Z direction) of the printed circuit board 540 with respect to the printed circuit board 540 is a bonding member. It is waterproofed by 560 , and one side of the printed circuit board 540 facing the 3-2 direction (-Z direction) may be waterproofed by the sealing member 550 . When at least one surface is in contact with the bonding member 560, stress due to a change in position that occurs when the user presses the key 530 may not be transmitted to the bonding member 560. Bending stress of the printed circuit board 540 drawn out of the key assembly 500 may not be transmitted to the bonding member 560.

Structurally, electronic devices may have an increased display screen area compared to the housing area. As the area of the display screen increases, the mounting space for the key assembly 500 is reduced and the area of the applicable sealing member 550 is reduced, which may cause problems with poor waterproofing.

According to a typical electronic device, the waterproof structure of the key assembly 500 may depend only on the adhesive force between the waterproof tapes. As the printed circuit board 540 and the waterproof tape overlap, excessive stress may occur between the first plate 510 and the second plate 520 of the key assembly 500. When the user presses the key 530 of the key assembly 500, the printed circuit board 540 disposed inside the key assembly 500 is also pressed, causing the waterproof structure of the printed circuit board 540 to be damaged, or You can become vulnerable. Since the adhesive area of the waterproof tape is not sufficient, the adhesive strength may be weak, which may cause the space between the waterproof tapes of the key assembly 500 to spread. To prevent this, a problem may arise that requires a long production time through a complex process.

According to one embodiment of the present invention, the bonding member 560 is applied to the printed circuit board 540 inside the key assembly 500 to fix the position of the printed circuit board 540 and improve waterproofing quality. .
