ABSTRACT:
The invention provides improved high voltage, low pass filtering connectors. The connectors described herein comprise an assembly having a low impedance path to ground for use in the connector. The assembly comprises a plurality of circuit elements which contribute a fixed amount of impedance to the ground path, a printed circuit board adapted to house the circuit elements, the printed circuit board further having a corresponding plurality of traces in electrical communication with the plurality of circuit elements wherein the traces are adapted to minimize in-line insertion loss to the circuit elements, and a plurality of ground planes in the printed circuit board electrically interfaced in the ground path for providing a low impedance path to ground for the signals bussed to the connector. Connectors described herein ensure efficient low pass filtering of signals at frequencies above the resonant frequency of the connector. Furthermore, the connectors described herein contain epoxy strips and adhesive coatings which prevent high voltage arcing from the circuit elements to other portions of the connector.
