Abstract: An electronic signal filter is provided, including a first filter housing having a filter cavity, a circuit board having a slot positioned within the filter cavity, and a ground clip. The ground clip includes a slot-retaining portion positioned within and in contact with an inner edge of the circuit board slot, at least one grounding arm engaged in solderless grounding contact with an inner surface of the filter cavity, and at least one grounding leg. Upon assembly, an end portion of a distal end of the slot-retaining portion intimately contacts a portion of the grounding leg interposed between the filter housing and the circuit board to achieve secure ground contact between the circuit board and the filter housing in a solderless manner.

Abstract: An electronic signal filter includes a cylindrical housing and a circuit board positioned therein having a plurality of peripheral edges and at least two circular through-holes formed therein. Each through-hole is inwardly spaced from one of the peripheral edges of the circuit board, defining a first distance between a respective one of the through-holes and a respective peripheral edge of the circuit board and defining a second distance between the through-holes. The filter also includes a ground strap attached to and spaced a distance above the circuit board. The ground strap includes a first portion, an integral second portion residing in and extending through each through-hole, and an integral third portion that contacts a portion of the second surface of the circuit board. At least a portion of the first portion of the ground strap contacts the inner peripheral surface of the cylindrical housing to ground the circuit board.
