Patent ID: 10186812

Abstract:
A connector assembly suppresses electromagnetic interference (EMI) generated by electronic circuitry on a printed circuit board (PCB). Certain embodiments of the connector assembly include common features such as conductive through-holes on the PCB, and a connector having terminal pins positionable through the conductive through-holes. The first embodiment includes a magnetic wafer positionable between the connector and the PCB. The second embodiment includes a plurality of stackable magnetic wafers positionable in a stack between the connector and the PCB. The third embodiment includes a magnetic cup wafer positionable between the connector and the PCB. The fourth embodiment, combines the cup wafer with the stackable magnetic wafers of the second and third embodiments. Each magnetic wafer includes wafer holes for the terminal pins to pass through. The magnetic wafers are configured to increase inductance and provide effective EMI noise suppression.
