AI Technical Summary
The ferrite core is prone to expand or contract when the temperature of the working environment changes, resulting in extrusion and fracture with the coil. The prior art lacks a high-strength structure to reduce this risk.
A chamfer is arranged between the groove bottom wall of the receiving groove of the core body and the groove side wall. The chamfer includes a C chamfer and two R chamfers, and the R chamfer is arranged on both sides of the C chamfer to enhance the strength of the core structure.
By setting the chamfer, the strength of the core is increased, deformation is reduced, and the risk of core breakage is reduced.

Technical Field
[0001] The utility model belongs to the technical field of magnetic cores, and particularly relates to a magnetic core structure with high strength. Background Art
[0002] A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability, high magnetic flux density, and low loss. Nickel-zinc ferrite has extremely high impedance and low magnetic permeability of less than a few hundred. Ferrite magnetic cores are used in coils and transformers of various electronic devices.
[0003] Due to the influence of the working environment temperature and its own heat generation, the ferrite magnetic core will expand and contract to varying degrees. During this process, it is extremely easy to be squeezed by the coil and break. Therefore, there is an urgent need for a magnetic core structure with high strength to improve the strength of the magnetic core structure and reduce the risk of fracture.
