Problems solved by technology

[0004] However, the above technical solution has the following problems: since all the turns of this coil are in one plane, this structure cannot be applied to axial coils, and this structure leads to an increase in the turn spacing, resulting in a large coil structure size

Embodiment 1

[0016] Embodiment 1: The interlacing mode between adjacent turns is continuously interlaced at a fixed interlacing angle from the initial turn. For example: make the first turn first, the second turn is staggered at an angle of a / 4 relative to the first turn, the third turn is also staggered at an angle of a / 4 relative to the second turn, and the fourth turn is staggered at an angle of a / 4 relative to the third turn, and so on Repeat the cycle until you complete the full circle.

Embodiment 2

[0017] Embodiment 2: The interlacing mode between adjacent turns is continuously interlaced at an unfixed interlacing angle from the initial turn. For example: make the first turn first, the second turn is staggered by an angle of a / 4 relative to the first turn, the third turn is staggered by an angle of a / 2 relative to the second turn, the fourth turn is staggered by an angle of 3a / 4 relative to the third turn, and so on Cycle until the full circle is complete.

Embodiment 3

[0018] Embodiment 3: The staggering method between adjacent turns takes the staggered axis of symmetry as the axis and staggers symmetrically at a fixed staggered angle, wherein the staggered axis of symmetry is the perpendicular bisector of one side of the first turn, and the perpendicular bisector is the same as the first turn The two sides of are parallel. For example: make the first turn first, the second turn is staggered to the left at an angle of a / 4 with respect to the axis of staggered symmetry, the third turn is also staggered at an angle of a / 4 to the right with the axis of staggered symmetry, and the fourth turn The phases are staggered to the left at an angle of a / 4 with the symmetrical staggered axis as the axis, and the cycle is repeated until the entire circle is completed.

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

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an inductance coil and an inductance. Background technique [0002] Most of the coils used in existing inductors adopt a structure with no spacing between turns. The overlap between the wires of each turn and the large distributed capacitance between turns will lead to an increase in the impedance of the coil and a decrease in the quality factor, which seriously affects its efficiency. It is accompanied by noise and electromagnetic compatibility. Even in some special fields, the system cannot work properly due to the large distributed capacitance. [0003] In order to solve the above technical problems, the Chinese invention patent with publication number CN104576003A provides the following technical solution: provide a wireless power transmission system coil with a planar spiral structure, each turn of the coil is a regular polygon, and the geometric center of each ...
