본 발명은 전기기기용 밀폐슬리브에 관한 것으로서, 보다 상세하게는 외부케이싱 및 내부패널 사이에서의 발포시 내부패널에 관통 결합되어 있는 전원커넥터로의 발포액 유입을 방지할 수 있도록 한 전기기기용 밀폐슬리브에 관한 것이다.The present invention relates to an airtight sleeve for an electric device, and more particularly, to an electric device that prevents a foam liquid from flowing into a power connector that is penetrated to an inner panel during foaming between an outer casing and an inner panel. Relates to a sleeve.

일반적으로, 냉장고 등과 같은 전기기기는 외부의 전원공급원으로부터 내부의 전원기구 각각으로 전원을 공급하게 되며, 이러한 전원기구는 내부에 분산 장착됨으로써 전원커넥터를 통해 통합 관리되는 복수의 리드선을 사용하여 전기적으로 연결된다.In general, an electric device such as a refrigerator supplies power to an internal power supply device from an external power supply source, and the power supply device is electrically distributed by using a plurality of lead wires integrated and managed through a power connector by being distributedly mounted therein. Connected.

종래의 전기기기는 도 1에서와 같이, 외부케이싱(1)과; 외부케이싱(1)의 내측에 마련되며, 커넥터결합홀(2)이 형성되어 있는 내부패널(3)과; 내부패널(3)의 커넥터결합홀(2)에 결합되는 전원커넥터(4)와; 내부패널(3)의 판면에 지지되어, 외부케이싱(1) 및 내부패널(3) 사이에서의 발포시 전원커넥터(4)로의 발포액(5) 유입을 방지하는 밀폐슬리브(6)를 포함하여 구성된다. Conventional electric equipment, as shown in Figure 1, the outer casing (1); An inner panel 3 provided inside the outer casing 1 and having a connector coupling hole 2 formed therein; A power connector 4 coupled to the connector coupling hole 2 of the inner panel 3; A sealing sleeve 6 supported by the plate surface of the inner panel 3 to prevent the inflow of the foaming liquid 5 into the power supply connector 4 when foaming between the outer casing 1 and the inner panel 3; It is composed.

특히, 전원커넥터(4)는 발포영역에 노출될 경우 각종 전기적인 문제점을 야기시킬 수 있으므로, 밀폐슬리브(6)의 밀폐부(6a)가 전원커넥터(4)에 연결되어 있는 판스프링(7)의 탄성력에 의해 내부패널(3)의 판면에 밀착 지지되는 구조를 지니고 있다. 이러한 밀폐슬리브(6) 구조는 이미 공지(등록번호:10-0334030)되어 있는 기술의 일부이므로 그 자세한 설명은 생략하기로 한다.In particular, since the power connector 4 may cause various electrical problems when it is exposed to the foamed area, the leaf spring 7 in which the sealing part 6a of the sealing sleeve 6 is connected to the power connector 4.
