INDUCTIVE ELEMENT Russian patent published in 2015 - IPC H01F17/04 H01F27/30 

FIELD: electricity.

SUBSTANCE: inductive element contains the coil assembly with the core and two flanges protruding in radial direction, formed at opposite end faces of the core. One of flanges is intended for fastening to printed-circuit board and its size is greater, than that of another flange. From the outer side the coil assembly is surrounded with the shading ring placed on the larger flange. For this purpose the shading ring at the lower end face has the step facing inwards one side of which forms the bearing surface placed on the inner side of the flange. Another side of the step forms the bearing surface thrusting against the external periphery of the flange. The step mainly passes along the whole periphery of the shading ring.

EFFECT: air gap formed between the upper flange and inner side of the shading ring is fixed in terms of its sizes and position.
