<p>This invention relates to filter structures for filter pin electrical connectors, and is more particularly concerned with pi filters for filter pin application. The prior art recognizes several approaches to the provision of pi filters for filter pin applications. Generally speaking, the pi filters have heretofore taken up too much space and were expensive. As an example, it is common in the art to provide a two unit multicapacitor with a ferrite insert and to connect the structure between the pin contact and the metal shell of an electrical connector. This requires two contacts to the capacitor terminations in two locations, one for each capacitor. An electrical connector assembly constructed in accordance with the present invention comprises a metal connector shell which carries a dieletric member therein. The dielectric member includes a contact passageway therethrough for receiving and mounting a pin contact. A hollow tubular inductance, in the form of a ferrite tube, is provided for receiving the pin contact therethrough. The ferrite tube has an inner electrical contact area on the inner surface which is electrically connected to the pin contact and at least one outer contact area on the outer surface which is electrically connected to the inner electrical contact area. A plurality of planar capacitor ground plates are spaced apart and connected in common to the metal connector shell, while another plurality of capacitor plates, the positive plates, extend between the ground plates and are electrically connected to the outer contact area of the ferrite tube.</p> |
