Patent number: 11980766Abstract: A self-centering washer is positioned between the feedthrough and filter capacitor of a filtered feedthrough. The washer has openings through which first and second terminal pins extend. A first opening has an inner arcuate portion contacting the first terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. A second opening has an inner arcuate portion contacting the second terminal pin and an outer perimeter portion exposing the braze sealing the terminal pin to the insulator. In an imaginary configuration with the first and second washer openings superimposed one on top of the other, the cumulative arcuate distance of the inner arcuate portions about one of the terminal pins, subtracting overlap, results in a gap between the superimposed washer openings that is less than a diameter of the first and second terminal pins so that the washer is prevented from lateral movement.Type: GrantFiled: October 6, 2023Date of Patent: May 14, 2024Assignee: Greatbatch Ltd.Inventors: Jason Woods, Robert A.
