Problems solved by technology
In the switching power supply circuit, the inductance device is connected with semiconductor devices such as switching tubes and diodes. During operation, the electromagnetic force changes due to the change of the magnetic circuit, which will cause core vibration and large noise. This noise exists in inductance inside the device, it is difficult to eliminate
[0003] The most serious vibration and noise part of the inductance device is generally the center column of the magnetic core. The traditional solution is to dispense glue on the center column of the magnetic core. The glue has the function of buffering force and bonding the two lobes of the magnetic core. The traditional solution uses adhesive as a damping material to alleviate the influence of the electromagnetic force of the core column on the magnetic core, but this method has a limited effect on the electromagnetic force, due to the instability of the adhesive, especially The buffering effect on electromagnetic force will also change after curing
For different applications, this method may not always achieve the desired effect

The embodiment of the invention relates to an inductance device and a manufacturing method thereof. The inductance device comprises an inductance coil and two magnetic cores, wherein the two magneticcores are stacked up and down in the mode that the opening positions correspond to each other, the inductance coil is wound around the middle columns of the two magnetic cores, a gap is formed betweenthe middle columns of the two magnetic cores, a structural piece is arranged in the gap, one or more cavities are jointly defined by the structural piece and the middle columns of the two magnetic cores, and the structure of each cavity enables the volume of air contained in the cavity to be stretched or compressed by magnetic field force generated by the middle columns of the magnetic cores in the working process. According to the inductance device, vibration of the magnetic core of the inductance device can be reduced, and noise generated in the inductance device is reduced.
Description
technical field [0001] The embodiments of the present application relate to the technical field of inductors, in particular to an inductor device and a manufacturing method thereof.
