Abstract

The invention relates to the field of magnetic ferrites, in particular to a ferrite magnetic core. The ferrite magnetic core is characterized by comprising a circular central cylinder and a square framework. One side of the square framework is provided with a U-shaped opening, and the circular central cylinder is arranged in the U-shaped opening. The ferrite magnetic core has the advantages that the magnetic core is in the stereoscopic structure of the central cylinder, is wound by windings completely except the tail end contacting with a PCB (printed circuit board) and is fine in shielding property. Meanwhile, the section of a wound coil is circular, so that winding of the coil is easier. Impact of an air gap reserved on a contact surface of two magnetic core pieces which are assembled is minimized by the aid of the unique shape, and the ratio of the size to the general space utilization rate is increased.

Description

technical field

[0001] The invention relates to the field of magnetic ferrite, in particular to a ferrite core. Background technique

[0002] The existing commonly used ferrite core is E-type, which has a simple and economical shape and a large effective area of ​​the core. However, the square cross-section is not easy to wind thick wires, and the magnetic shielding is also poor. It is not suitable for low-leakage transformers such as pulse transformers or broadband transformers. magnetic requirements. Therefore, it is necessary to design a new type of ferrite core, which should have a cross-section that is easy to wind a coil and should have good magnetic shielding performance. Contents of the invention

[0003] The object of the present invention is to overcome the above problems and provide a ferrite core with a circular cross-section, easy to wind coils, small flux leakage and high effective permeability.

[0004] In order to achieve the above object, the technical s...
