Problems solved by technology

Due to the different functions used on the equipment and the increase in the number of circuit modules, there are more requirements for high-performance inductors. In addition, the miniaturization of the design also requires the use of further miniaturization and thinning, but the inductance of the current inductors is not high enough. , increasing the number of coil turns will increase the cost

Embodiment Construction

[0016] Such as Figure 1 to Figure 4 As shown, an inductor 100 includes an outer frame 10 with an opening, a cylindrical magnetic core 20 accommodated in the outer frame 10 , and a coil 30 wound on the magnetic core 20 . The outer frame 10 is rectangular parallelepiped and openings at both ends run through the entire outer frame 10 , and both the outer frame 10 and the magnetic core 20 can be made of alloy material or ferrite material. The coil 30 wound on the magnetic core 20 is a round copper wire, and the coil 30 has been wound before assembly. The inductor 100 also includes a magnetic glue 40. When the magnetic core 20 and the coil 30 are housed in the outer frame 10, the magnetic glue 40 is applied to the surface of the coil 30 from the two openings of the outer frame 10, so as to achieve the function of magnetic shielding. The effect increases the inductance of the product, and the thickness of the magnetic glue 40 gradually decreases from the middle to both ends. The ...

Abstract

The invention discloses an inductor, which comprises an outer frame provided with an opening, a magnetic core contained in the outer frame, and a coil wound on the magnetic core. The inductor also comprises magnetic glue, wherein the magnetic glue is sealed on the opening of the outer frame to increase the inductance value of a product and perform the effect of magnetic shielding.

Description

[0001] 【Technical field】 [0002] The invention relates to an inductor, in particular to magnetic glue coated on the surface of the inductor coil. [0003] 【Background technique】 [0004] Inductors are widely used as small-scale power inductors and power inductors, and are widely used in mobile phones, DVDs, portable audio equipment, notebook computers and other equipment. The above-mentioned devices require the inductance to be small in size and light in weight, and at the same time, they are often required to be able to operate for a long time. Due to the different functions used on the equipment and the increase in the number of circuit modules, there are more requirements for high-performance inductors. In addition, the miniaturization of the design also requires the use of further miniaturization and thinning, but the inductance of the current inductors is not high enough. , if the number of coil turns is increased, the cost will increase. [0005] Therefore, it is neces...
