Filtered electrical connector
First Claim
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.

Abstract
A filter connector comprising a conductive housing containing a pin array traversing corresponding holes in a grommet, a dielectric body, a planar capacitor array, ferrite inductor beads mounted on at least some of the pins, a non-conductive body to insulate said beads from one another and from said capacitor, a non-conductive seal, a second capacitor array, a second grommet, a second interface seal a grounding cylinder surrounding said capacitor arrays and said beads in an electrical contact with a ring of contact fingers mounted in the interior of said housing. Optionally, a conductive O-ring encircles said shell, to improve shielding.
