ABSTRACT:
An electric noise suppressor is provided for suppressing high-frequency electric noise which comprises a thermoplastic housing and two ferrite members disposed therein. The thermoplastic housing is formed from two hingedly connected case halves, which are substantially identical. A ferrite member is secured to each case half by a laminated compressible adhesive-foam element, which is comprised of a resilient foam core layer and opposing adhesive layers disposed thereabout. Due to the resiliency of the foam core layer, the ferrite members are pressed into tight engagement within the thermoplastic housing. The end walls of the thermoplastic housing are formed with circular apertures, which are each formed with a diameter which is slightly smaller than the diameter of the cable which is engaged by the electric noise suppressor. The dimensional differences between the cable and the apertures allows the end walls to grippingly engage the cable at a predetermined location. With the electric noise suppressor being in a closed position, the thermoplastic housing ensures the ferrite members encircle a predetermined location along the length of a cable. A locking arrangement may be provided with the thermoplastic housing to maintain the thermoplastic housing in a closed position at the predetermined location.
