Description

Technical Field

The rapid development of the electronics industry has promoted the refined demand for inductor performance. Modern inductors have realized flexible adjustment of inductance values by introducing technologies such as adjustable magnetic cores, sliding contacts, or electronic controls, meeting the dynamic requirements of different circuits for inductance parameters.

[0003] The patent application with the application number CN202022405623.0 discloses an inductor that is convenient to adjust the inductance intensity, including a base, a magnetic core assembly installed on the base, and several coils respectively installed in the magnetic core assembly. The magnetic core assembly includes four identical magnetic core monomers. Each magnetic core monomer includes a base portion, wall portions perpendicularly extending in the same direction from both sides of the base portion, and a core portion extending in the same direction as the wall portions from the middle of the base portion. The core portion includes a core body sleeve.
