1. A multi-pin filtered electrical connector providing EMI filtering, for as many as desired of pins in said connector, which filter connector comprises:

  • a multiplicity of electrical pins;

    a first non-conductive grommet seal provided with openings for said pins, said first grommet being positioned at the outer face of a dielectric body;

    said dielectric body having openings corresponding to said pins;

    a first planar body having openings corresponding to said pins;

    a first planar ceramic capacitor array having openings corresponding to said pins, positioned against said dielectric body;

    ferrite inductor beads mounted on and around each of said pins which are desired to be filtered;

    a non-conductive elastomer body provided with openings to accept each of said beads and each of the non-filtered pins, and to insulate said ferrite beads from each other and from said first capacitor array, said elastomer body being positioned against said first capacitor array;

    a first non-capacitor interface seal, provided with openings for said pins, positioned against the outer face of said elastomer body;

    a second planar ceramic capacitor array having openings corresponding to said pins, positioned against said first interface seal;

    a second non-conductive grommet seal, provided with openings for said pins, positioned at the outer face of said second capacitor;

    a second non-conductive interface seal, provided with openings for said pins, positioned at the outer face of said second grommet;

    a conductive grounding cylinder encircling said second grommet seal and said first capacitor array and also a portion of said dielectric body, and capable of being placed into electrical contact with said grounding cylinder;

    a conductive shell adapted for housing said pins, seals, dielectric body, elastomer body, capacitor arrays, and ground cylinder; and

    supported within said shell, a conductive ring element providing a multiplicity of resilient contact fingers for making electrical contact with said grounding cylinder and providing an electrical grounding path from said pin array to said shell.
