Card retention assembly

A card retention assembly for retaining a plurality of expansion cards of the type having a mounting bracket including a securing tab within the chassis of an electronic device, the card retention assembly comprising:

• a tab retaining surface suitable for receiving the securing tab of each of the plurality of expansion cards received in the chassis so that the securing tab rests against the tab retaining surface;
• an arm assembly capable of being moved between an open position and a closed position, the arm assembly having an inner end attached to the chassis and an outer end suitable for at least partially engaging the tab retaining surface when the arm assembly is moved to the closed position, the outer end of the arm assembly including a channel formed therein for at least partially enclosing the tab retaining surface when the arm assembly is in the closed position and a plurality spring members disposed within the channel for engaging the securing tab of each of the plurality of expansion cards retained in the chassis when the arm assembly is in the closed position to at least partially restrain the securing tab against the tab retaining surface,
• wherein, when the arm assembly is moved to the closed position, the arm assembly is suitable for securing the plurality of expansion cards in the chassis.
