US Patent 7428148 Component support

A component support having at least one insert card reception chamber with two insert card guidance devices, which have oppositely located guides for receiving at least one insert card. The guides are arranged and spaced apart from each other by a size of a height of the insert card. Insert cards of different structural height can be installed in the component support if the insert card receptacle is divided at a half of the height between the two guides by a guide rail. The guide rails, together with the guides of the insert card guidance devices, form partial receptacles, into which printed circuit boards of a reduced insert card height can be introduced.
