Patent ID: 7429908

Claim:
A coil form for forming an inductive element with a core and at least two coils, including a) a hollow coil body for insertion of the core, the coil body having an outer surface b) and at least one separating plate which surrounds the outer surface of the coil body thereby providing at least one coil area on the surface of the coil body, wherein c) the coil body is made of plastic and includes at least one recess on its outer surface for positioning and holding the at least one separating plate, d) the separating plate is made of metal, having an opening for pushing the separating plate over the coil body and having a slit for prohibiting leakage currents within the separating plate, e) the separating plate forms a winding of one of the at least two coils f) and in that another coil of said at least two coils includes an insulated wire wound around the coil body in said at least one coil area, the separating plate being a side support for said wire and dissipating heat generated within the wire.
