본 고안은 전기기기 등 각종 장치의 전선이나 케이블 등을 고정하는 복합 케이블 그랜드에 관한 것으로서, 좀더 상세하게는 피팅 등의 부품을 하우징 내부로 삽입되게 결합 구성하여 내외부를 차단하는 기밀구조를 제공함은 물론 유니언의 내부로 고이는 수분을 차폐상태에서 즉시 외부로 드레인 배출하여 각종 안전사고의 위험성을 방지하는 드레인구조를 갖는 복합 케이블그랜드에 관한 것이다.The present invention relates to a composite cable gland for fixing wires or cables of various devices such as electric devices, and more specifically, to provide a gas tight structure to block the inside and outside by combining components such as fittings to be inserted into the housing. The present invention relates to a composite cable gland having a drain structure which prevents the risk of various safety accidents by immediately draining moisture accumulated in the union to the outside in a shielded state.

일반적으로 전기기기 등 각종 장치의 케이싱 내부에서 외부로 인출된 전선이나 케이블을 장치의 케이싱 일측에 견고하게 고정시킴과 동시에 케이싱의 내부와 외부가 차단된 상태를 유지하면서 방수, 방염, 방폭을 제공하도록 케이블 그랜드(Cable grand)를 사용하고 있다.In general, to secure the wire or cable drawn out from the inside of the casing of various devices such as electrical equipment to one side of the casing of the device to provide a waterproof, flameproof, explosion-proof while maintaining the state of the casing is blocked. I use a cable grand.

이러한 케이블 그랜드는 본 출원인에 의해 등록실용 제20-376324호에 선 출원 및 등록받은 바 있는데, 이는 피팅의 일측에 캡너트가 결합되고, 타측은 고무패킹과 함께 그랜드(부싱) 내부에 삽입되어 결합되되, 상기 고무패킹이 내부에 삽입되는 케이블을 압착하여 실링을 행하게 구성된다.This cable gland has been filed and registered in advance by the applicant in the registration room No. 20-376324, which is a cap nut is coupled to one side of the fitting, the other side is inserted into the gland (bushing) with rubber packing The rubber packing is configured to compress the cable inserted therein to perform sealing.
