Abstract

A waterproof housing with a plug-and-socket connection for protecting electronic circuits includes a hard plastic upper part and a hard plastic lower part. A soft plastic extruded seal is disposed between the upper part and the lower part. A plug part is constructed in one piece with the upper or lower part. The plug part has a hard plastic inner part containing contact pins and a soft plastic sealing collar surrounding the inner part.

Claims
