发明名称 Trap filter assembly
摘要 A trap filter assembly, of the type which can be employed with a video cable system to block a particular channel or band of channels and pass the remaining video signal, is formed of a circuit board, a centrally-disposed cylindrical ground block, and a housing formed of male and female housing halves which are press-fit over the circuit board onto the ground block. The housing halves form a solderless connection with the ground block, and the latter forms a solderless connection with ground pads on the printed circuit board. A slot cut in the cylindrical ground block receives the printed circuit board, and a zig-zag channel structure formed in one wall of the slot permits a zig-zag signal lead to extend from one end of the printed circuit board through a ground area of the board, to the other end thereof.
