In a rack system for inserting electrical printed circuit board assemblies, front elements (52,8) for slots are provided with projecting plug-in and withdrawable centering and contact elements (13,49). These elements have associated receiving elements (16,21) composed of electrically conductive material and are mounted with low impedance to a transverse connecting rail (36,38). During an insertion process, the receiving elements and the centering and contact elements come into contact in a centered manner. When inserted, the receiving elements and the centering and contact elements provide a vibration-proof mechanical connection with a high adhesion force and a low-impedance contact with a high current carrying capacity.

[ What is claimed is:] [1.]1. A rack system, comprising:a mounting rack having an insertion side and slots;electrical printed circuit board assemblies structured to be inserted into the slots in an insertion direction from the insertion side of the mounting rack;opposite transverse connecting rails mounted at the mounting rack and made of electrically conductive material to bound the slots;receiving elements made of electrically conductive material and mounted at the transverse connecting rails at the insertion side of the mounting rack so as to provide a low-impedance contact between the receiving elements and the transverse connecting rails, wherein each of the receiving elements is associated with one of the slots; andplug-on and plug-off front elements made of electrically conductive material, wherein each of the front elements is associated with one of the slots and wherein each of the front elements has at least one centering and contact element, the centering and contact elements projecting in the insertion direction and being plugged into or withdrawn from a corresponding one of the receiving elements; wherein the centering and contact elements and the receiving elements are structured to be in a mechanically centered contact during an insertion process of the centering and contact elements into the receiving elements, and wherein, in a completely inserted state, the centering and contact elements and the receiving elements respectively provide a vibration-proof, highly adhesive mechanical contact and an electrically low-impedance contact with a high-current carrying capacity.
