[0002] The high frequency anti-interference inductance coil of multilayer subsection winding is a kind of special inductance coil, mainly used in high-frequency circuit to reduce interference and improve the stability of circuit, and the high frequency anti-interference inductance coil of multilayer subsection winding is wound along the length direction of inductance coil by wire, and the multiple layers of coil are staggered, and the adjacent coils are partially overlapped. This structure makes that there is no overlapping part between the coils, only a wire is left at each end point, and these wires are connected along the direction of coil shell or core column, forming a compact structure.

[0003] At present, the high frequency current of the existing high frequency anti-interference inductance coil of multilayer subsection winding can cause the current density of wire surface layer to increase during use, and the magnetic field between wires interferes with each other, the resistance loss increases significantly, and heat is generated. Although the multilayer subsection winding can reduce the distributed capacitance, the increase of the winding density and the interlayer insulation material in the coil hinder heat conduction. If the heat cannot be quickly dissipated during use, the heat will accumulate in the central area, causing the service life of the inductance coil to be shortened. Therefore, we propose a high frequency anti-interference inductance coil of multilayer subsection winding. UTILITY MODEL CONTENTS
