ABSTRACT:
A filter connector is provided which is rugged and can be constructed at very low cost. The connector includes a front shell of metal which has a rearwardly-facing ledge, a circuit board device which includes a board of insulative material with a circuit layer on its rearward face, a rear insulator with a front portion lying within the rear of the front shell, and several contacts extending through holes in the circuit board device and insulator. The circuit layer includes capacitors around holes through which the contacts extends, with each contact soldered to a terminal of the capacitor, and the edge of the circuit soldered to the front shell. The rear insulator is molded in place to the circuit board device and within the rear of the front shell, with some of the insulator extending rearwardly of the front shell. The portion of the insulator extending rearwardly of the front shell is devoid of any metal shell immediately surrounding it.
