Abstract:
1. An electronic signal filter comprising: a cylindrical housing adapted to be electrically grounded and having a first end, an opposed second end and an inner peripheral surface defining an interior compartment; a circuit board positioned within said interior compartment of said cylindrical housing, said circuit board having a first surface and an opposed second surface, said circuit board substantially dividing said interior compartment into a first compartment defined by said first surface of said circuit board and a first portion of said inner peripheral surface of said cylindrical housing, and a second compartment defined by said second surface of said circuit board and a second portion of said inner peripheral surface of said cylindrical housing, said circuit board further having a plurality of peripheral edges and at least two circular through-holes formed therein, each said through-hole being inwardly spaced from one of said peripheral edges of said circuit board, defining a first distance between an outer peripheral portion of a respective one of said through-holes and a respective peripheral edge of said circuit board and defining a second distance between respective centers of said through-holes; and a ground strap attached to and spaced a distance above said circuit board, said ground strap having a first portion extending from said first surface of said circuit board and spanning a portion of said circuit board over at least said second distance, an integral second portion residing in and extending through each said through-hole, and an integral third portion immediately adjacent said second portion, said third portion contacting a portion of said second surface of said circuit board; wherein at least a portion of said first portion of said ground strap contacts a portion of said inner peripheral surface of said cylindrical housing to ground said circuit board.
