Abstract
A filter electrical connector includes a plug housing, a center housing and a receptacle housing connected in series by a number of connecting screws. The plug housing and center housing define a central filter cavity. The plug housing and receptacle housing provide means for receiving electrical connectors associated with an electronic device requiring EMI filtering. A T-type filter arrangement is provided within the filter cavity of the connector adapter. The filter arrangement includes PC board mounted capacitors, each in electrical connection between a corresponding connecting pin and a robust common ground. This ground is extended through the ground plane of the PC board, to the plug housing, through an electrical gasket to the conductive case of the electrical device requiring the EMI filtered signal. Each connecting pin extends through corresponding openings in a pair of ferrite wafers. Each one of the pair of ferrite wafers is situated on opposite sides of the PC board to sandwich the capacitors therebetween.
