Filter connector with latchable mounting frame

Claim 1

A filter connector adapted to releasably latch in a metal chassis of an electrical apparatus comprising a filter unit formed of a flat substrate of electrically insulating material having a plurality of filter capacitor elements formed on at least one side thereof, a plurality of contact elements extending through apertures in said substrate aligned with said filter capacitor elements, each of said contact elements being in electrical contact with one of said filter capacitor elements, a common ground electrode formed along at least one of peripheral lateral side edges of said substrate, and a mounting frame of electrically conducting material having a flat base with a plurality of apertures therein corresponding to said contact elements, said filter unit being secured to said mounting frame so that a bottom surface of said flat substrate rests adjacent a top surface of said flat base and the contact elements extending from said bottom surface of said flat substrate pass through said respective corresponding apertures in the flat base, said common ground electrode being in electrical contact with said mounting frame, a plurality of resilient mounting lips formed integrally with said flat base, each said mounting lip extending away from a bottom surface of the flat base at an angle so as to extend beyond the planes of one or the other of the respective lateral peripheral sides of the flat base, whereby when the filter connector is inserted through an aperture in the metal chassis, said mounting lips are resiliently flexed inward toward said planes of said lateral peripheral side of the substrate until fully inserted into the chassis aperture when said mounting lips return to their initial position to releasably latch and electrically connect said filter connector to said metal chassis.
