ELECTRONIC DEVICE HAVING WATERPROOF STRUCTURE

According to one embodiment of the present disclosure, an electronic device may comprise: a housing comprising a first through hole, which is formed so as to pass through a lateral surface, and a second through hole which is disposed adjacent to the first through hole and formed so as to pass through the lateral surface; a protruding portion disposed so as to at least partially face the second through hole inside the housing; a socket disposed inside the housing so as to be aligned with the first through hole; a push bar disposed on one side of the socket so as to be linearly reciprocatable, and at least partially aligned with the second through hole; and a waterproof pin accommodated in the second through hole to seal the second through hole, and formed so as to move the push bar by linearly reciprocating inside the second through hole by an external force. In one example, when the waterproof pin reaches a designated location in the second through hole, a first area of one end face of the waterproof pin comes into contact with the push bar, and a second area, different from the first area, of the one end face of the waterproof pin comes into contact with the protruding portion. Various other embodiments are possible.
