Problems solved by technology

[0006] However, housings with a pressure relief hole have the disadvantage that dirty water can penetrate into the interior through this hole
[0011] In current solutions, the structurally increased effort required for the pressure equalization between the housing interior and the surroundings has proven to be disadvantageous

Embodiment Construction

[0033] figure 1 A not further illustrated first housing part 1 of the housing according to the invention, which is produced from plastic and is embodied as a housing lower part, is shown. The housing serves to accommodate the electronic control unit, so that special requirements must be met with regard to protection against environmental influences. For this purpose, the first housing part 1 is in a position of use not shown in relation to the image 3 A second housing part 8 , identifiable in , is gas-tightly connected along a sealing surface 3 delimiting a contact plane 2 . In order to compensate for pressure fluctuations, the first housing part 1 has an elastically deformable region 4 which deforms outwards in the event of an overpressure, thereby providing a seal between the housing parts 1 , 8 in the figure 2 The sealing element 7 shown in is pushed outwards onto the bearing surface 5 in the plane of the sealing surface 3 .

Abstract

The invention relates to a housing for accommodating at least one technical functional unit. A first housing part (1) is connected to a second housing part (8) by means of a sealing element (7) along a sealing surface (3), which adjoins a support surface, which is integrally connected to the sealing surface, on the outside. At least one housing part (8) has an elastically deformable deformation area in order to compensate pressure fluctuations. Thus, the housing part (8) can be moved together with the sealing element (7) in the contact plane from the sealing surface (3) to the support surface so that pressure equalization is accomplished by means of the groove-shaped openings of the support surface, which allow for flow under the sealing element (7). According to the invention, the sealing element (7) is covered at the outer periphery thereof by a projection (9) of the second housing part (8). The second housing part supports the return of the sealing element (7) after a displacement for the purpose of the pressure equalization.

Description

technical field [0001] The invention relates to a housing, in particular a housing made of synthetic material, for accommodating at least one technical functional unit, in particular an electronic component, wherein the housing has at least two housing parts, the At least two housing parts are gas-tightly connected to each other in a contact plane along the sealing surface, at least one housing part having an elastically deformable deformation region for compensation of pressure fluctuations. Furthermore, the invention relates to the arrangement of sealing elements in such housings. Background technique [0002] Such housings, for example for electronic or mechatronic functional units, are produced in large quantities. Such housings enable adequate protection of the functional units arranged in the housing, especially when used under harsh ambient conditions, as in vehicles. In particular, uncontrolled ingress of water into the housing must be prevented. For this purpose,...
