Description

The invention relates to a housing with a seal. Liquid-tight sealed housings are well-known in the prior art because it is a typical requirement to house a moisture-sensitive component in a liquid-tight sealed enclosure. The housing is designed in two parts: a first housing part and a second housing part. When their facing surfaces meet, these parts form a gap that must be sealed. It is known that a seal is inserted into the gap, resting against the two opposing surfaces. However, this design has disadvantages with regard to sealing and durability. If, for example, the seal lifts away from one of the surfaces at only one point, the seal is no longer guaranteed. It is also known that a groove is incorporated into one of the two opposing, facing surfaces, and a complementary projection is provided on the other opposing surface, with a seal arranged between the opposing surfaces. The projection forms a continuous circumferential ridge. However, such a design has also proven disadvantageous with regard to sealing and durability. In certain situations, particularly with steam, it is possible for the steam to overcome the projection and penetrate into the interior of the housing. Furthermore, a continuous circumferential ridge can prevent water from draining out of the interior of the housing. The document DE 21 2015 000 078 U1 reveals a seal with grooves and compatible projections on the sealing surfaces of housing parts. The object of the present invention is to create a housing with a seal which is improved in terms of sealing compared to the prior art and yet is easy to manufacture. The problem is solved using the features of claim 1. One embodiment of the invention relates to a housing with a seal, comprising a first housing part and a second housing part enclosing an interior of the housing. The first housing part has a first surface, and the second housing part has a second surface, which, in the closed state, face each other and form a gap between them. The first surface forms a first sub-surface and a second sub-surface, and the second surface forms a third and a fourth sub-surface. The first sub-surface forms a first groove, and the second sub-surface forms a second groove. The third sub-surface forms a first projection compatible with the first groove, and the fourth sub-surface forms a second projection compatible with the second groove, such that, in the closed state of the housing, the first projection engages in the first groove, and the second projection engages in the second groove. A seal is arranged in the gap between the first housing part and the second housing part. This ensures improved sealing of the housing, particularly against water and steam, and this sealing is permanent. It is particularly advantageous if the first surface is offset by one step relative to the second surface, and if the third surface is offset by one step relative to the fourth surface, each in a direction perpendicular to the surfaces. This achieves a particularly good sealing effect, as the step, especially when moving from the outside to the interior of the housing, must be overcome, resulting in a further improved seal. In one embodiment, it is also advantageous if the step has a height H and the first projection a height h1 and the second projection a height h2, where H is greater than h1 and H is greater than h2, in particular H is several times greater than h1 and h2, or at least three times greater than h1 and h2. This also achieves an improved sealing effect. It is particularly advantageous if the third surface adjacent to the interior of the housing is positioned higher than the fourth surface adjacent to the exterior. This would cause the water to rise inwards to penetrate the housing. Since this would have to occur against gravity, the sealing effect is improved. It is also advantageous if the first projection and/or the second projection is designed as a circumferential or nearly circumferential projection, with the first groove and/or the second groove also being designed as a circumferential or nearly circumferential groove. This enables a sealing variant that is easy to manufacture and easy to assemble. It is also advantageous if the first projection and/or the second projection are subdivided into partial projections that are arranged in a row to form an essentially circumferential or nearly circumferential projection, and if the first groove and/or the second groove are subdivided into partial grooves that are arranged in a row to form an essentially circumferential or nearly circumferential groove. This makes another sealing variant possible. It is also advantageous if the first projection and/or the second projection, or the partial projections of the first projection and/or the second projection, are straight or curved, wherein the first groove and/or the second groove, or the partial grooves of the first groove and/or the second groove, are straight or curved. This curved variant is advantageous
