Clip buckle type magnetic ring in electronic equipment in the, we often can see, has many magnetic ring and convergence cable constitute a inductance device (cable in the of wire in magnetic ring Shang around several circle as inductance coil), magnetic ring is electronic circuit in the common of anti-interference components, on high frequency noise has is good of shield role, so was called absorption magnetic ring flat shaped magnetic ring, due to usually using ferrite information made, so and said buckle type magnetic ring also said, block button type magnetic ring, assembled type magnetic ring, assembly type magnetic ring referred to magnetic ring.
