도 1 내지 도 3에서 도시된 바와 같이, 본 발명의 일 실시예에 따른 전기 자동차용 충전기의 실링장치는 하우징(10), 밀봉부(20), 수분차단부(30) 및 커버부(40)를 포함한다. As shown in Figures 1 to 3, the sealing device of the charger for an electric vehicle according to an embodiment of the present invention is the housing 10, the sealing portion 20, the moisture blocking portion 30 and the cover portion 40 It includes.

하우징(10)은 케이블(C)이 삽입되는 부위에 설치홈부(11)가 함몰 형성된다.In the housing 10, the installation groove 11 is recessed in a portion where the cable C is inserted.

이러한 하우징(10)은 전기 자동차의 충전을 위한 전기부품들을 수용하여 외부로부터 안전하게 보호한다. 이때, 설치홈부(11)는 밀봉부(20), 수분차단부(30) 및 커버부(40)가 설치될 수 있는 공간을 제공한다. The housing 10 accommodates electrical components for charging the electric vehicle to protect it from the outside. At this time, the installation groove 11 provides a space in which the sealing portion 20, the moisture blocking portion 30 and the cover portion 40 can be installed.

밀봉부(20)는 케이블(C)이 관통 가능하게 삽입되는 삽입부(21)와, 삽입부(21)에 돌출 형성되어 설치홈부(11)의 일측면에 접촉되는 접촉부(22)를 포함한다.The sealing part 20 includes an insertion part 21 through which the cable C is inserted so as to penetrate therethrough, and a contact part 22 protruding from the insertion part 21 to be in contact with one side of the installation groove 11. .
