Amorphous magnetic ring inductor facilitating wire winding

Abstract

The invention relates to the technical field of inductors, in particular to an amorphous magnetic ring inductor facilitating wire winding. The inductor structurally comprises an annular magnetic core, a first coil, a second coil and a partition board, wherein the first coil and the second coil are wound on the two sides of the annular magnetic core respectively, and the partition board is arranged on the annular magnetic core and used for separating the first coil from the second coil. The inductor further comprises a bottom plate and a support capable of being detachably connected with the bottom plate and the annular magnetic core. The annular magnetic core comprises a shell and nanocrystalline alloy disposed in the shell. The bottom plate and the annular magnetic core are detachably connected through the support, so that the bottom plate and the annular magnetic core can be conveniently installed, connected and detached. If the amorphous magnetic ring inductor facilitating wire winding goes wrong in use, the annular magnetic core can be detached from the bottom plate and repaired. The amorphous magnetic ring inductor facilitating wire winding has the advantages of being small in size, excellent in performance and simple in structure, and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of inductors, in particular to an easy-to-wind amorphous magnetic loop inductor. Background technique [0002] In many electronic equipment, the circuit or device itself will generate a certain amount of electromagnetic interference, especially the electronic equipment gradually tends to be miniaturized, and multiple electronic components are closely crowded together, which is more prone to electromagnetic interference problems, and the electronic equipment Excessive electromagnetic interference will interfere with the normal operation of other surrounding electronic equipment, or interfere with other electronic devices. Inductors are often used in electronic equipment. They are commonly used anti-interference components in electronic circuits. They have a good shielding effect on high-frequency noise and can be used for anti-interference filtering and energy storage. In addition, existing inductors usually...

AI Technical Summary

Problems solved by technology

And the existing inductors usually use ferrite and iron powder cores as magnetic cores, while common mode inductors generally use ferrite cores, which are not very effective for some circuits, and the volume is too large

With the development of high power, high frequency and low power consumption, the previous ferrite magnetic materials can no longer fully meet the requirements

That is, the inductors in the prior art have an unsatisfactory suppression effect on conducted interference, and are prone to saturation in the case of strong current interference, and the performance stability is not very good in the case of large temperature changes, and the change is non-linear. prone to problems

The frequency characteristics are relatively smooth, which cannot meet the filtering requirements of different bands, and the impedance value is difficult to make high, etc. A series of problems

[0003] Existing inductors usually use the method of connecting the lead wires to the pins on the base plate after winding. However, since the base plate and the magnetic ring are separated, it is difficult to assemble and fix the base plate and the magnetic ring, and glue is required. To fix the magnetic ring and the bottom plate, the installation connection between the magnetic ring and the bottom plate is not firm, and the installation efficiency is low, which makes the production efficiency low, and its repairability is relatively poor

Because the bottom plate and the magnetic ring are fixed by dispensing glue, and the glue cannot be disassembled after it dries, so if there is a problem with this inductor, it is basically impossible to repair it
