Abstract
A high frequency noise suppressor for engagement around a cable comprises a pair of case halves made of nylon or other rugged synthetic material which can be snapped around a cable in clam shell like fashion. A ferrite core half is positioned in each case half for defining a ferrite core member around the cable. Each case half has opposite end walls with semicircular recesses. A plurality of triangular fingers extend into each recess and are positioned at a slight angle outwardly with respect to an interior of each case half. The fingers have truncated apexes for defining a small opening in each recess. If a cable which is larger than the small opening is to be engaged by the suppressor, the fingers bend outwardly on opposite sides of the case for firmly engaging the cable. This resists relative movement between the closed case and the cable in either direction along the cable.
