Patent ID: 7692927

Claim:
A shielding and heat dissipation device comprising: a conductive bracket ( 1 ) provided on a Printed Circuit Board (PCB) around a shielded heat-generating electronic component arid electrically connected to a conductive layer of the PCB; and a heat sink ( 2 ) arranged above the heat-generating electronic component ( 3 ) and provided with a conductive surface electrically connected to the conductive bracket ( 1 ), a shielding case ( 9 ), wherein a bottom of the shielding case ( 9 ) is electrically connected to the conductive layer of the PCB, the conductive surface of the heat sink serves as a top of shielding case ( 9 ) so as to form a complete shielding cavity with said shielding case ( 9 ), and the conductive bracket is arranged within the shielding cavity in the shielding case and is connected to the shielding case.
