Description

Technical Field

[0002] Ferrite cores are high-frequency magnetic materials primarily used in the manufacture of high-frequency transformers and high-frequency magnetic rings, and are widely used in instruments, communication equipment, and household appliances. However, existing ferrite cores still have some shortcomings in practical use. For example, traditional ferrite cores are typically installed using bolts, a method prone to stripping during operation. Once stripped, the core must be removed and re-tightened, increasing installation steps and time, causing significant inconvenience to users. Furthermore, under high-frequency conditions, existing UB-type cores exhibit high losses and require improvement in permeability, limiting their application in high-efficiency electronic devices.
