Unitary die-cast assembly for electronic circuits

Claim 1

An assembly housing for electronic circuits, the assembly comprising a unitary die-cast, said unitary die-cast having at least a pair of compartments, each for receiving a circuit board, the two compartments being partitioned by a wall, said wall having a channeled cavity for providing a thermal separation between the two compartments whereby said wall acts as a thermal insulator, at least one of said compartments forming a housing with a cavity for receiving a circuit board therein, said housing being made of a rigid and a highly acoustically dampening material, a cover adapted to cover said housing and enclose the cavity, said cover being a rigid but flexible material, and means for forcibly fastening the cover to the housing through an aperture situated substantially at the center thereof, said fastening means comprising a center tap post positioned substantially in the center of the cavity, said post being an integral part of the die-cast, and a threaded screw adapted to fasten said cover forcibly onto the housing through a tap in the center of the cover so that the force applied to the cover by the tightened screw applies pressure onto the cover whereby the pressure applied to the cover causes the cover to apply lateral and downward pressure to provide microphonically enclosed and dampened housing for said circuit board.
