Abstract: A housing for electronic components that includes a tubular, extruded aluminum, mid-section, a flat or plate-like front panel and a die-cast double-domed rear wall. Arranged in one of the domes of the rear wall is a printed circuit board with first female plugs. Fitting through the second dome, from the outside, are second female plugs, to which outwardly-leading cables are attached. Circuit boards with integrated electronic circuits slide into the housing and are secured laterally by guide grooves integral with the middle section of the housing. The boards, at their frontal edges, make contact through their male plugs with the appropriate ones of the female plugs. The boards are further secured by fitting into notches in a reinforcement rib between the two domes. A strip having three contact points is secured, if desired, to each circuit board for the purpose of reducing mechanical vibration. Each circuit board can be replaced individually. For this purpose, withdrawal arms are provided.
