Abstract
A modular card cage allows for improved access to the rear panel of a backplane, while providing for enhanced EMI shielding. First and second side panels, in combination with top and bottom covers, form the card cage. The top and bottom covers are adapted for removably mounting to the side panels, and, when mounted, provide lateral rigidity to the card cage. At least one of the top and bottom covers comprises a front portion and a rear portion. The front portion of the cover is preferably separable from the rear portion such that one of the front and rear portions is removable from the side panels, while the other of the front and rear portions remains mounted for providing lateral rigidity. EMI shielding is provided in all portions of the cage, including the removably mounted covers, preferably by means of embedded, continuous gasketing. In this manner, a cost effective card cage is provided that is relatively simple to assemble and provides improved lateral and torsional rigidity over conventional configurations, while maintaining EMI shielding requirements.
