The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in FIG. 1, FIG. 1 is the structural perspectives of integrally formed inductor in the prior art.In Fig. 1, inductor sheet
Conductive coil 2 is provided in body 1, two electrode slices 3 extend to 1 inside of inductor body from 1 side of inductor body and leading
The outer fix of electric coil 2 is connected with end turn.It is limited by space, the spacing between 2 outside of conductive coil and electrode slice 3
It is smaller, and only only there are two the spaces between electrode slice 3 in the space of receiving setting conductive coil 2.
Conductive coil 2 in inductor inevitably generates heat when being powered on, and the coil of conductive coil 2 is straight
The smaller fever of diameter is more serious, and the fever of conductive coil 2 will have a direct impact on the working performance of inductor in inductor.Conventional inductance
Device is limited by volume size, the coil diameter of conductive coil 2 can not be arranged it is excessive so that conductive coil is during the work time
Fever is serious, so that the reduced performance of inductor 2.In addition, electrode slice 3 and 2 outside interplanar distance of conductive coil are smaller, it is conductive
The insulating layer of the outer surface of coil 2 is easy to wear and occurs short circuit between electrode slice 3.
