Abstract
The utility model discloses a 8-shaped magnetic core, which comprises a 8-shaped magnet sheet. The center of the 8-shaped magnet sheet is provided with an oval magnet post. Both ends of the oval magnet post are provided with arc magnet sheets. The arc magnet sheets are respectively arrayed on both sides of the oval magnet post. The 8-shaped magnetic core has simple structure, wherein the contact area of the magnet post is large so as to increase the inductance figure of the magnetic core.
Description
Technical field:
The utility model relates generally to a kind of figure of eight flat thin magnet.
Background technology:
When making transformer, inductance, add magnetic core in the coil, can increase inductance value and quality factor, the reduction of device volume.The magnet piece that uses is that magnetic column is arranged in magnet piece mostly at present, but the contact area of magnetic column is less, and inductance coefficent is not high enough.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of figure of eight flat thin magnet to be provided, and its magnetic column contact area wherein is big, the inductance coefficent height.
The utility model is achieved through the following technical solutions:
A kind of figure of eight magnetic core is characterized in that having a figure of eight flat thin magnet, and there is an oval magnetic column in described figure of eight flat thin magnet central authorities, and there is the arc-shaped magnet sheet at described oval magnetic column two ends, and the arc-shaped magnet sheet is respectively in oval magnetic column both sides.
The utility model is simple in structure, and magnetic column contact area wherein is big, has strengthened the inductance coefficent of magnetic core.
Description of drawings:
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is a front view of the present utility model.
Embodiment:
A kind of magnetic core includes a figure of eight flat thin magnet 1, and there is an oval magnetic column 2 in described figure of eight flat thin magnet 1 central authorities, and there is arc-shaped magnet sheet 3 at described oval magnetic column 2 two ends, and arc-shaped magnet sheet 3 is respectively in oval magnetic column 2 both sides.
