Abstract

The invention provides an inductance coil; its turns is of regular polygonal structure arrayed in the same lead angle along the same axis; the adjacent turns are in staggered contact; in the inductance coil and the inductor, the adjacent turns are arranged in the same lead angle; the adjacent turns are in non-overlapping contact; therefore the overlapping area of the adjacent turns is reduced, the spaces among the turns are increased at the same time, the distribution capacitance is greatly reduced; it is tested that under the same conditions of lead specifications, turns and turn sizes, compared with the current inductance coil, the distribution capacitance of the inductance coil provided by the invention is reduced by 50 %-80, the heat radiation effect is good, and various high current demands can be satisfied. The invention also provides an inductor.

Description

Inductance coil and inductance

Technical field

The present invention relates to technical field of electronic equipment, particularly a kind of inductance coil and inductance.

Background technology

Existing inductance coil used adopts the structure of turn-to-turn distance continuously mostly, overlap between every circle wire, turn-to-turn distributed capacitance is large, the impedance of coil can be caused to increase, quality factor reduce, and have a strong impact on its efficiency, and are attended by the shortcoming such as noise, Electro Magnetic Compatibility difference, even at some special dimension, system is caused just cannot normally to work because distributed capacitance is large.

For solving the problems of the technologies described above, publication No. is: the Chinese invention patent of CN104576003A provides following technical scheme: the radio energy transmission system coil providing a kind of planar spiral structures, every circle coil is regular polygon, and the geometric center of each regular polygon is all positioned at same point, the emphasis on any polygonal summit of circle and adjacent turn polygon limit is just right, and this loop construction solves high effective ways of the plane class stary capacity of coil.

But technique scheme exists following problem: because all circles of this coil are all in a plane, this structure cannot be applied to axial class coil, and this structure causes turn-to-turn apart from increasing, and causes loop construction size large.

Summary of the invention

In view of this, be necessary to provide a kind of turn-to-turn distributed capacitance little and circle line axially-aligned inductance coil.

There is a need to provide a kind of inductance.

A kind of inductance coil, its circle is the regular polygon structure arranged with identical lead angle along common axis line, interlacing contact between described adjacent turn.

A kind of inductance, comprises above-mentioned inductance coil.

In above-mentioned inductance coil and inductance, adjacent turn is with the arrangement of identical lead angle, and adjacent turn not overlying contact, so make the overlapping area between adjacent turn diminish, increase the spacing of turn-to-turn simultaneously, to make to reach the object significantly reducing distributed capacitance.After tested, under the measure-alike condition of wire gauge, the number of turn and circle, the more existing inductance coil of distributed capacitance of inductance coil provided by the invention can reduce by 50% ~ 80%; And good heat dissipation effect, various big current requirement can be met.
