Abstract
A housing for an electronic circuit configuration includes a housing seal disposed on an inner surface of the housing, integrally bonded to at least one outer housing wall and made of a liquid silicone elastomer. An electrical connecting element extends from the interior of the housing through an outer housing wall and out of the housing. A space between the outer housing wall and the electrical connecting element is sealed by the housing seal.

A housing for an electronic circuit configuration, the housing comprising:
- an inner housing wall, an outer housing wall and a housing interior;
- a housing seal disposed on said inner housing wall and connected in an integrally bonded manner to said outer housing wall, said housing seal being formed of an elastomer manufactured from a liquid silicone;
- an electrical connecting element guided out of said housing from said housing interior through said at least one outer housing wall;
- said inner housing wall having an extension extending towards said outer housing wall, said outer housing wall having an extension extending towards said inner housing wall, said electrical connecting element extending through said extension of said inner housing wall and said extension of said outer housing wall, and said housing seal surrounding said extension of said inner housing wall and said extension of said outer housing wall;
- and
- said outer housing wall and said electrical connecting element forming a gap therebetween being sealed by said housing seal.
A method for sealing a housing for an electronic circuit configuration, the method comprising the following steps:
- providing the housing with an outer housing wall and an inner housing wall, wherein the inner housing wall has an extension extending towards the outer housing wall, and the outer housing wall has an extension extending towards the inner housing wall;
- providing an electrical connecting element extending through the extension of the inner housing wall and the extension of the outer housing wall;
- sealing the inner wall of the housing by using a housing seal connected in an integrally bonded manner to outer housing wall;
- sealing a gap between the outer housing wall and the electrical connecting element guided out of the housing from an interior of the housing through the outer housing wall by using the housing seal, the housing seal surrounding the extension of the inner housing wall and the extension of the outer housing wall;
- and
- providing the housing seal with at least one sealing region formed from an elastomer injection molded from a liquid silicone.
