ABSTRACT:
A card cage for holding printed circuit cards comprising modular cage elements each having a pair of parallel slots formed therein and spaced apart a distance to slidably receive the edges of a printed circuit card and to retain said card therein. The said modular elements are stacked together, one upon the other, to form the card cage with each module having contact retaining cavities formed in the corners thereof. Securing means in the form of conductive rods or bolts extend through the corner edges of the stack of card holding modules to supply the required power supply voltages into the card cage system and also to secure together the stack of modules. Such conductive rods are exposed to the cavities in the ends of the modules. Individual contact means retained in the cavities connect the rods or bolts to conductive areas on the corners of the individual printed circuit cards and thereby supply the power voltages to said cards.
