ABSTRACT:
A noise suppressor for engagement over a cable or ribbon, has a pair of ferrite core halves held in a pair of case halves which are closed around the cable or ribbon. The noise suppressor has a pair of case portions made of resilient material, each case portion having opposite side walls and a floor for defining a space with an open top for receiving a ferrite portion, and ends for passing the conductor. Hinges and latches or latches only hold the case portions together in a closed position around a conductor with the open tops of the case portions facing each other. Ferrite portions are in each case portion, each ferrite portion having a channel and at least one face. The faces engage each other and the channels merging when the case portions are in the closed position for passage of the conductor through the channel. A raised platform on the floor of each case portion is made as one piece with the case portion and extends into the space and into engagement of the ferrite portion. The platform is spaced inwardly of the opposite side walls and ends of the case portion for allowing the ferrite which is in engagement with the platform to rock so that when the case portions are in the closed position, the faces engage flatly against each other and are held securely in that position by a slight distortion of the top and bottom case floors.
