Abstract

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.
