Abstract: An EMI shielded system in which a motherboard is permanently shielded behind a shielding plate defining an aperture for each corresponding connector carried by the motherboard so as to allow expansion cards or the like to be connected to the motherboard without having to unshield the latter. The expansion cards are preferably separately mounted and shielded within respective loading cartridges.

Abstract: A system (22) for removably connecting a circuit card, such as an extension card (54), to an electronic device, comprises a sliding component (28) adapted to support the circuit card (54) and having a guiding edge (32) configured to be slidably inserted in a channel (26) disposed adjacent a connector (20) of the electronic device so as to position the card mating edge (56) in register with the connector (20). A lever (40) is provided for lowering the mating edge 56 of the extension card (54) until suitable connection is made between the card connector and the connector (20). Advantages of the present invention include the fact that the system allows for ergonomic insertion and removal of extension cards without the need for manual dexterity on behalf of the user.
