It is also conceivable for the printed circuit board to be fastened to the attachment interface by means of a material-locking connection, such as by adhesive bonding. The printed circuit board preferably has a side facing the housing unit and a side facing the interior of the housing unit, particularly the housing device. The electronics unit preferably has cooling ribs arranged on the side of the printed circuit board facing the housing unit, preferably at least in contact with the printed circuit board.

The at least two side walls preferably extend at least substantially parallel to one another. The at least partially open side preferably extends at least substantially perpendicular to at least one of the side walls. Preferably, the two side walls and the at least partially open side are at least partially integrally formed with one another.
