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.
