Patent ID: 7489224

Claim:
A ferrite core assembly for suppressing electromagnetic interference, comprising: a plurality of ferrite cores, each having a respective head end with a rounded, convex shape and a respective tail end with a rounded, concave shape that provides a recess, each ferrite core additionally having an intermediate region between its head and tail ends, wherein each ferrite core comprises sintered material at the head end thereof, sintered material at the tail end thereof, and sintered material at the intermediate region thereof, wherein the ferrite cores are assembled in articulated, flexible sequence such that the head ends of at least some of the ferrite cores extend into the recesses of adjacent ferrite cores, and wherein the head ends of the ferrite cores have approximately the shape of a spherical cap of a sphere with a predetermined radius, and the tail ends of the ferrite cores have approximately the shape of a spherical cap of a sphere with a radius that is approximately the same as the predetermined radius.
