Application No. 09/592,058
providing a first circuit board that includes the connector, the connector
having: a conductive outer shell, and one or more receptacles for receiving
signals that are coupled to components on the first circuit board, and
providing suppression plate that is configured to provide a galvanically
isolated high frequency coupling between the conductive outer shell of the
connector and the chassis in proximity to the opening of the chassis that receives
the connector when the first circuit board and the suppression plate are attached
to the chassis, wherein the suppression plate includes a second circuit board,
and
attaching the first circuit and the suppression plate to the chassis.
15. An EMI suppression plate comprising:
a circuit board that includes:
one or more contact items that provide electrical contact between a
conductive outer shell of a connector and a first conductor on the circuit board,
and
one or more capacitors that are configured to couple high
frequency signals from the first conductor on the circuit board to a second
conductor on the circuit board that is configured to become electrically coupled to
a chassis ground when the EMI suppression plate is attached to a chassis,
thereby providing galvanic isolation between the outer shell of the
connector and the chassis ground while also providing a high frequency coupling
between the outer shell of the conductor and the chassis ground.
Weidler's invention relates to an electrical connector which is capacitively
coupled to the chassis of an electrical device. As shown in Figures 1-9, Weidler's
invention is a capacitive coupling assembly 60 for an electrical connector 10, where the
connector comprises a dielectric housing 12 holding a plurality of contacts 16 and a
conductive shell 14 on the housing. The capacitive coupling assembly 60 is electrically
coupled to the conductive shell 14, and comprises a dielectric member 61 which is
sandwiched between conductive sheets 62, 63, the dielectric member 61 holding one or
