Abstract: An explosion-proof housing for a power electronics unit includes a housing pan and a cover that closes the housing pan via a seal, wherein the cover and the housing pan are pressed against each other at two opposing sides formed by edge regions of the cover and the housing pan via a plurality of fasteners that are configured to be released by rotation and that engage in latching structures. The plurality of fasteners are arranged in a central third of the respective sides. The explosion-proof housing can be used, for example, for a photovoltaic inverter.

Abstract: A housing of an electrical device for converting electrical power has a main body with a rear wall, side walls and a cover. The cover and body define a an interior space. Components of the electrical device are arranged in the interior space. The cover is connected to the body by a cover closure that includes a fastening structure and a closure housing. The fastening structure is retained in the closure housing, which is fastened to the cover. The body includes a pin that extends from the rear wall of the housing to the cover. A connection between the cover and pin is releasable by turning the fastening structure using a guide peg of the pin and a helically encircling guide groove of the fastening structure.

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.
