Patent ID: 8624697

Claim:
A magnetic component assembly, which includes: a top cover; a bottom cover, wherein each of the top and bottom covers are respectively symmetrical and have a cylindrical cup-like shape and a centrally arranged through hole and a rectangular hole arranged at a side at the side, and wherein the top and bottom covers are cold-formed of insulating magnetic powder of iron or Fe—Si with a width range of the rectangle hole of 0.5 mm to 10 mm, and a diameter of the top and bottom covers is 20 mm to 120 mm and wherein a wall thickness of the top and bottom covers is more than 1 mm and wherein the top and bottom covers define a magnetic field path and provide environment protection; a separate solid cylindrical rod core of cold-formed insulating Fe—Al—Si with 0.1% to 10% copper magnetic powder and having reduced release friction and increased green part strength and an outer diameter less than an inner diameter of the through holes in the top and bottom covers and a length of more than 52 mm; and a coil wound on the rod core so as to provide an inductive magnetic field with two electrical connectors at two ends wherein the electrical connectors extend through a respective rectangular hole of the top and bottom covers separately and wherein the top cover is glued to the bottom cover.
