Coil set for iron-cored inductors, a coil former for the coil set, and a method for producing the same

摘要

A coil set for iron-cored inductors, a coil former for the coil set, and a method for producing the same. The coil body of the iron-cored inductor is provided with a cylindrical or quadrilateral cavity for the iron core and the coils are wound on walls which run parallel to the outer surface of the cavity. Two or more - interleaved coaxially in one another - coil formers are provided in the coil body. That wall of the first coil former which carries the coil partially surrounds the coil which is carried by the second coil former, and a side wall of the first coil former projects into the second coil former, at least partially bounding the internal space.
