Abstract: The disclosure relates to a housing for a power electronics device, including a tray for receiving power electronics components and a cover for placing on the tray so that a closed housing is formed. The cover is fixed on the tray by a plurality of fixing screws. At least one opening element is provided that is made of one of the fixing screws, each of which is guided through a sleeve with deformation structures. The sleeve is arranged between the screw head of the fixing screw and the housing such that a pressing force is exerted by the screw head between the cover and the tray via the sleeve. The deformation structures are designed such that under the effect of the force of an explosion that exceeds the pressing force, the sleeve is compressed in a manner defined by the deformation structures such that a gap with a specified width is formed between the cover and the tray.

Abstract: The disclosure relates to a housing of an electrical device for converting electrical power, including a main body and a cover. The cover closes the main body to define a self-contained interior space, wherein electrical and electronic components of the electrical device are arranged in the interior space of the housing. The cover is connected to the main body via a detchable securing structure, which may be arranged in the geometrical center of the cover. An electrical device has a housing of this type.

Abstract: A method for testing the adhesion of elastic adhesives or elastic sealing materials on surfaces of components including: a) applying the adhesive/sealing material to a component surface, b) attempting by exerting a peeling force to detach the applied adhesive/sealing material from the component surface, and c) assessing the adhesion of the adhesive/sealing material on the basis of fractures caused in the adhesive/sealing material and the detachment of the adhesive/sealing material from the component surface by the exertion of the peeling force. Prior to and/or during step a), an anti-adhesion material layer is applied to at least one first part of the component surface, which causes poorer adhesion of the adhesive/sealing material to the component surface and therefore can be detached from the component surface with less peeling force than directly from the component surface.
