Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The existing inductor has the technical problem of low magnetic core utilization rate, so that a longer magnetic core needs to be arranged, and the height of a product is influenced. Therefore, an object of the present invention is to provide an inductor to improve the utilization ratio of the magnetic core, shorten the height of magnetic core and product.

Example one

Referring to fig. 1 to 2, an inductor 10 according to an embodiment of the present invention is shown, which includes a magnetic core 11 and a winding 12 wound on the magnetic core 11. Wherein:

In the present embodiment, the wire section of the winding 12 is specifically a square structure, but the present invention is not limited thereto, and in other embodiments, the wire section of the winding 12 may also be a square or oval structure, so that compared with a conventional round wire, the gap between the wire and the wire may be shortened, and the turns of the wire may be arranged closer to each other.

In practical implementation, the conducting wire of the winding 12 is preferably a copper wire, and the magnetic core 11 is preferably made of a material with good magnetic permeability, such as a soft magnetic material. Meanwhile, the shapes and sizes of the magnetic core 11 and the winding 12 are not limited herein, and may be adjusted according to actual use requirements.

Based on the flat structure, the distance between two adjacent circles of wires of the winding 12 can be controlled to be 0.1-0.3 mm, and the packaging height of a product can be reduced by 15%.

To sum up, in the inductor 10 of the present embodiment, since the cross section of the wire of the winding 12 is flat, the gap between the wire and the wire can be shortened, so that the wire of each coil can be arranged closer to each other, and more winding wires can be wound on the same magnetic core 11, thereby improving the utilization rate of the magnetic core 11 and shortening the heights of the magnetic core 11 and the product. Meanwhile, the inductor 10 further extends an electrical connection portion 121 from each of two ends of the winding 12, so that the subsequent inductor wiring is facilitated.
