Abstract
The invention relates to a housing for an electric or an electronic component, in particular a motor vehicle control unit, for which the housing parts or housing connections are designed such that the electric or electronic components are sealed watertight and airtight. Such housings, which are composed if only in part of a thermoplastic synthetic material, are provided with a pressure compensation feature. As a result, the pressure inside the housing is constantly adapted to the outside pressure. With this type of pressure adaptation, it is not possible for gases, particularly water vapor, to permeate the synthetic housing under pressure and reach the electric or electronic components. As a result, damage caused by humidity is greatly reduced and the service life is increased.
