ABSTRACT:
A condensed profile electrical connector to be used in electrically coupling a flexible conductor connector plug to a primary printed circuit board. The electrical connector includes a support unit (11) having a secondary printed circuit board (17) and a connector housing (18), a first plurality of conductors (12) for electrical connection to the flexible conductors, a second plurality of conductors (13) for connecting the first plurality of conductors (12) to the primary printed circuit board, a third conductor (14) comprising a conductive material disposed over a substantial portion of one side of the secondary printed circuit board (17) for providing a ground plane, and a plurality of capacitors (16) for capacitively coupling each of the first conductors (12) to the third conductor (14) for providing EMI filtering. The electrical connector may be connected to the primary printed circuit board in a minimum of profile area (32) and, once connected, provides beneficial EMI filtering and RF filtering.
