Patent ID: 7218198

Claim:
A coil form for forming an inductive element with a core comprising: a) at least two coils, b) a hollow coil body for insertion of the core, the coil body being made of an electrically insulating material and c) at least two separating plates which surround the outer surface of the coil body thereby providing at least one coil area on the outer surface of the coil body for holding a wire that forms a part of a coil, wherein d) each separating plate is made of metal, includes an opening for pushing the separating plate over the coil body and a slit for prohibiting short circuits and leakage currents within the separating plate, and in that the separating plate forms a winding of another coil; e) the separating plates are spaced at a specific plate-distance, f) where a ratio of the plate-distance to a diameter of the wire is between 1 and 2.
