Problems solved by technology
[0008] The main purpose of the present invention is to provide a magnetic element to solve the disadvantage that the existing magnetic element tends to make the overall volume larger when increasing the air gap distance between the two poles of the magnetic core group and then adjusting the inductance of the magnetic element
[0009] Another object of the present invention is to provide a magnetic element to solve the problem that the center pillar is difficult to grind due to the obstruction of the side pillars in the production of the existing magnetic element, resulting in more time and cost. shortcoming

Embodiment Construction
[0050] Some typical embodiments embodying the features and advantages of the present invention will be described in detail in the description in the following paragraphs. It should be understood that the invention is capable of various changes in different forms without departing from the scope of the invention, and that the description and drawings therein are illustrative in nature and are not intended to limit the invention.
[0051] see Figure 2A, which is a schematic structural diagram of the magnetic element in the first preferred embodiment of the present invention. As shown in the figure, the magnetic element 2 of the present invention is mainly composed of a conductive winding structure and a magnetic core group 22. In this embodiment, the conductive winding structure includes a winding frame 21 and a coil 23 wound thereon, but does not use This is the limit. In some other embodiments, the conductive winding can also be a pie structure wound only by coils, and its i...

The invention provides a magnetic component comprising a conducting winding structure, a first magnetic core part with a first central column, a second magnetic core part with a second central column and a plurality of side columns, wherein at least one side column is arranged on the side of the first magnetic core part or the second magnetic core part and others are arranged on other corresponding sides of the first magnetic core part or the second magnetic core part. When the first magnetic core part is assembled with the conducting winding structure and the second magnetic core part, the conducting winding structure is arranged between the first magnetic core part and the second magnetic core part, and the first central column corresponds to the second central column so as to enable the side columns to respectively correspond to the sides which are not provided with the side columns. The total height of the first central column and the second central column is less than the height of the side column so as to reserve gap between the first central column and the second central column.
Description
technical field [0001] The invention relates to a magnetic element, in particular to a magnetic element which is small in size and suitable for assembly. Background technique [0002] Generally speaking, there are often many magnetic components in electrical equipment, such as transformers, inductance components, etc., and in order to adapt to the thinning of electrical equipment, the magnetic components and the conductive windings used inside must also develop towards a thinner trend to reduce electrical equipment. of the overall volume. [0003] Taking the inductance element as an example, the existing inductance element such as Figure 1A As shown, as shown in the figure, the inductance element 1 is mainly composed of a winding frame 11, a magnetic core group 12 and a coil 13, wherein the winding frame 11 has a winding slot 111 for winding the coil 13 thereon, There is also a through channel 112 in the bobbin 11, and the bottom of the bobbin 11 has a plurality of pins 11...
