Abstract
A rack assembly (1) includes cross-connecting bars (5) and guide bars (15) for printed circuit boards (59). These guide bars each include a fixing device (36) for the placement of a receiving element (17) which has a contact zone (37) and is placed into electric contact on a cross-connecting bar. The invention also provides for front elements (13) having centering contacts (25) that protrude into, and thereby come into contact with, the contact zone, in a low-ohmic, current-carrying manner, when the front element is set in place. The receiving element preferably has a contact blade (54) which extends into a guide groove (26) of the guide bar.
