Patent ID: 8462514

Claim:
An electronic device, comprising: a housing; a circuit board; a tray operative to receive a module, the module in communication with the circuit board when the tray is inserted in the housing, the tray comprising at least one detent, the tray further comprising a proximal end and a distal end, the proximal end located adjacent to the periphery of the housing and the distal end located directly opposite the proximal end; a cage coupled to the housing and forming an enclosure between the housing and the cage for receiving the tray; a ramp positioned such that an end of the tray rests on top of the ramp when the tray is fully inserted within the housing, wherein the ramp is operative to bias the removable module towards the cage when the tray is fully inserted within the housing; a first displaceable spring operative to engage the at least one detent; a secondary displaceable spring operative to retain the first spring engaged with the at least one detent to retain and substantially immobilize the module within the tray; and a compression spring coupled to a portion of the housing and positioned between the distal end of the tray and the secondary spring when the tray is inserted in the housing, the compression spring being directly compressed by the distal end of the tray toward the portion of the housing when the tray is inserted in the housing, and the portion of the housing being aligned with the distal end of the tray.
