INDUCTANCE COIL Russian patent published in 2015 - IPC H01F17/02 H01F5/02 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and can be used in frequency filters for radio devices for various purposes, e.g. in harmonic filters of high-power high-frequency radio transmitters. An inductance coil, comprising a cylindrical layer winding with spacing on an assembling frame, consisting of two side panels lying in parallel and connected to combs in the form of bars with a rectangular cross-section with grooves for the wire, wherein the winding is made from an insulated wire with a circular cross-section in the form of N coils laid in corresponding grooves of the combs to form turns with a non-circular shape and connected in parallel, wherein each turn of each coil has N edges, where M is the number of combs, from which two diametrically opposite combs lying in the same plane have a longer length, protrude from the side panels and have a hole for fastening. The coils are divided into K parts, where K=2, 3, 4…, wherein the turns of each subsequent part of the coils are shifted by one groove from the turns of the previous part of the coils, where in each part of the coils, the wire of each subsequent coil is laid in the corresponding grooves on top of the wire of the previous coil, and each turn of the wire of each of the parts of the coils is a broken line and has K shifts by one groove into the neighbouring plane of the winding. Each side panel is provided with a metal plate mounted thereon, having at least N+1 holes, from which N holes are intended for fastening wires at the beginning and at the end of each winding by soldering, and one hole is intended for installing an additional contact, wherein each side panel also has at least N+1 holes interfaced with holes in the metal plate mounted in the side panel, wherein the remaining M-2 combs also have a longer length and protrude from the side panels.

EFFECT: broader functional capabilities of the inductance coil.
