INDUCTANCE COIL Russian patent published in 2016 - IPC H01F17/02 H01F5/02 

FIELD: electrical engineering.

SUBSTANCE: invention is related to electric engineering and may be used in frequency filters for wireless devices for various applications, for example, in harmonic filters of powerful high-frequency radio transmitters. Inductance coil comprises layer cylindrical winding form wire with pitch, arranged on collecting frame. Frame is made up of two plates, connected to each other and located parallel to each other. First plate is located inside winding and has at ends two rows of slots to accommodate wires with pitch equal to pitch of winding. Second plate is located outside winding and has at ends slots for winding leads. Both plates along the length project beyond end surfaces of winding and are equipped in this part with holes for fastening plates with each other and together with winding by means of screw connection. Wherein width of first plate at end parts, as well as distance between opposed slots in their lower part are equal to inner diameter of winding. Row of slots at one end of first plate is shifted relative to row of slots at other end by half pitch.

EFFECT: technical result consists in design simplification, reduced labor input and possibility of adjusting inductance.
