Problems solved by technology

[0002] With the rapid development of the electronics industry, the performance requirements of products are getting higher and higher. With the continuous upgrading of high-end electronic equipment and technological innovation, it directly drives the further development of electronic components. In the existing technology, inductors are the core electronic components. , the coil usually needs to be die-cast with the magnetic material, so that the terminal is determined on the side of the magnetic core, and the terminal usually protrudes from the side of the magnetic core, but its disadvantage is that it is noisy below 20KHZ

Abstract

The invention discloses an inductor which comprises a coil and a magnetic core, wherein the coil is accommodated in the magnetic core, one end of the coil is connected with a first terminal, and the other end of the first terminal extends to the outside of the magnetic core and is bent; the other end of the coil is connected with a second terminal, and the other end of the second terminal extendsto the outside of the magnetic core and is bent. An inductor forming method comprises the following steps that S1, a coil and a terminal are welded and put into a mold cavity of a mold, the mold is filled with a powdery magnetic material, and a product consistent with the mold cavity in shape is formed after pressurization; S2, the product is heated and cured; S3, the terminal of the cured productis bent. By means of the technical scheme, the product has the advantage of being low in noise.

Description

technical field [0001] The invention relates to the technical field of inductors, in particular to an inductor and a processing and forming method for the inductor. Background technique [0002] With the rapid development of the electronics industry, the performance requirements of products are getting higher and higher. With the continuous upgrading of high-end electronic equipment and technological innovation, it directly drives the further development of electronic components. In the existing technology, inductors are the core electronic components. , the coil usually needs to be die-cast with the magnetic material, so that the terminal is determined on the side of the magnetic core, and the terminal usually protrudes from the side of the magnetic core, but its disadvantage is that it is noisy below 20KHZ. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the inventor has found through long-term research that when faced with th...
