Problems solved by technology

The magnetic module is at least composed of permanent ferrite and enameled wire wound on the permanent ferrite. The permanent ferrite is mixed with iron oxide and strontium (or barium, etc.) Manufactured, the finished permanent magnet ferrite has a relatively regular shape. If you need an irregular permanent magnet ferrite, it is more difficult to manufacture. In addition, the enameled wire is wound on the permanent magnet ferrite by manual or mechanical automation. tougher

Embodiment Construction

[0012] see Figure 1 to Figure 4 As shown, the magnetic module 100 of the present invention is used to be welded on a circuit board (not shown) to reduce noise and electromagnetic interference of the product, which includes a plastic magnet 10 and several coils 20 wound on the plastic magnet 10 . Magnetic materials are added to the heat-melted plastic material and injected into the mold cavity by high pressure. After cooling and solidification, the plastic magnet 10 is formed, that is, the plastic magnet 10 is made by injection molding. The magnetic material includes NdFeB, silicon steel, non-magnetic Crystalline, nanocrystalline, ferrite, magnetic powder core, etc., the plastic magnet 10 has the same performance as the permanent ferrite in the prior art. The plastic magnet 10 in this embodiment is rectangular, but according to the needs of the product, by changing the structure of the mold cavity, the plastic magnet 10 can be easily injection molded into any regular or irregu...

Abstract

A magnetic module comprises a plastic magnet and a coil wound on the plastic magnet. The plastic magnet is formed by adding magnetic material into plastic material. The shape of the magnetic module can be changed by changing the shape of the plastic material after undergoing forming so that the shape of the magnetic module can be changed easily, and finally the magnetic module required by a product is obtained.

Description

technical field [0001] The invention relates to a magnetic module, in particular to a magnetic module with plastic magnets. Background technique [0002] Network interface connector RJ45 usually has a magnetic module to filter noise. For the prior art related to this case, please refer to an electrical connector disclosed in Chinese Patent Publication No. CN 101964485A. The connection module and the magnetic module, the transfer module is used to connect with the mother circuit board, the sub-circuit board is connected between the conductive terminal and the transfer module, and the magnetic module is installed on the sub-circuit board to achieve conductive The terminal is connected to the magnetic module and the transfer module through the conductive circuit on the sub-circuit board. [0003] The electrical connector can filter noise and reduce electromagnetic interference by setting a magnetic module. The magnetic module is at least composed of permanent magnet ferrite ...
