Winding system of high-frequency inductance coil

Abstract

The invention discloses a winding system of a high-frequency inductance coil. The system comprises a spiral inductance coil formed by plastically bending a copper wire, a gap is formed between every two adjacent circles of the spiral inductance coil, and the continuous gaps form a spiral insulation heat dissipation gap consistent with the spiral path of the spiral inductance coil; according to theinvention, the copper wire is gradually and spirally wound into the spiral inductance coil; the space between every two adjacent circles of the spiral inductance coil is rigidly restrained by the spiral distance restraining pile; and the distance between any two circles of the spiral inductance coil is strictly restrained by the spiral distance restraining pile, so that the situation that two circles of copper wires are close to each other in the winding process of the spiral inductance coil due to uneven internal stress in the copper wires in the winding process is avoided.

Description

technical field [0001] The invention belongs to the field of inductor preparation. Background technique [0002] Air-core inductors have only coils and no iron core. High-frequency large inductors need to use air-core inductors, which need to be wound on the reel before taking off the reel; high-frequency, especially high-current inductors, in order to enhance heat dissipation, A predetermined gap should be formed between two adjacent coils, and they cannot be close together. The existing reels are all polished rods. Although they are wound according to a predetermined helical pitch during the winding process, two coils may still appear in the actual operation process. When the copper wires are close to each other, if two coils of copper wires are close to each other, if the enameled wire close to each other is damaged, a short circuit will occur, which will make a circle of copper wires invalid, and the close proximity will also affect heat dissipation, so It is necessary ...

[0002] Air-core inductors have only coils and no iron core. High-frequency large inductors need to use air-core inductors, which need to be wound on the reel before taking off the reel; high-frequency, especially high-current inductors, in order to enhance heat dissipation, A predetermined gap should be formed between two adjacent coils, and they cannot be close together. The existing reels are all polished rods. Although they are wound according to a predetermined helical pitch during the winding process, two coils may still appear in the actual operation process. When the copper wires are close to each other, if two coils of copper wires are close to each other, if the enameled wire close to each other is damaged, a short circuit will occur, which will make a circle of copper wires invalid, and the close proximity will also affect heat dissipation, so It is necessary to strictly control the helical pitch between two adjacent turns of copper wire in the process of winding the coil
