ABSTRACT:
A ferrite toroid retainer 10 provides an apparatus for retaining ferrite toroids 1 on an electrical cable 2 to prevent chafing of the cable's insulation. The device is constructed from an elastomer material. Ferrite toroid retainer 10 is constructed from a toroidal sleeve 11 having an inside diameter B equal to that of the outside diameter A of electrical cable 2. The outside diameter C of ferrite toroid retainer 10 is equal to that of the inside diameter F of ferrite toroid 1. A retaining ridge 12 is attached around the circumference of one end of toroidal sleeve 11 and has a tapered leading edge 13. Attached around the circumference of the opposite end of toroidal sleeve 11 is a non-tapered retaining ridge 15. Perpendicular edges 14 prevent ferrite toroids 1 from sliding off of toroidal sleeve 11.
