ABSTRACT:
A module support structure is proposed for printed circuit boards which can be inserted on guide rails. The four parallel module rails of the module support structure to which the guide rails are mounted are connected to the two parallel side walls via a special mounting technique. Specially shaped mounting bolts are used with a head bolt having a flat seating surface, a substantially cylindrical threaded shaft, as well as a transition piece disposed between the bolt head and the threaded shaft and tapering in a conical manner towards the threaded shaft. The mounting bolts are fed through cylindrical mounting holes in the module rails. During tightening, the transition piece abuts against the outer edge of the mounting holes to force the module rails against the projections disposed above or below the mounting holes. In this manner, an exact positioning of the module rails relative to the side walls is necessarily effected. The outer edge of each mounting hole can be deformed by the transition piece until the seating surface of the corresponding bolt head seats on the side wall.
