Embodiment Construction

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0028] see Figure 1 to Figure 4 , the high-current coil inductor provided by the present invention will now be described. A high-current coil inductor includes a coil 1, a first lead wire 11 and a second lead wire 12. The coil 1 is spirally wound with a single-layer enameled wire; the first lead wire 11 is connected to the lower end of the coil 1 and extends along the coil. The second lead wire 12 is connected to the upper end of the coil 1 ; the second lead wire 12 extends downward along the side surface of the coil 1 and is located on one side of the first ...

Abstract

The invention provides a large-current coil inductor and belongs to the technical field of electronic components. The large-current coil inductor comprises a coil, a first lead-out line and a second lead-out line. The coil is formed by spirally winding a single-layer enameled wire; the first lead-out line is connected with a lower end of the coil and arranged along the radial direction of the coil; the second lead-out line is connected with an upper end of the coil; the second lead-out line extends downwards along a side surface of the coil; and the second lead-out wire is positioned on one side of the first lead-out wire. The invention provides the large-current coil inductor. By means of the mode, the first lead-out line and the second lead-out line are arranged below the coil at the same time and can be directly and electrically connected below the coil, and meanwhile, the second lead-out line is bent along an outer side face of the coil, so that the whole large-current coil inductor is flattened, and the space occupied by the large-current coil inductor in the using process is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and more particularly, relates to a high-current coil inductor. Background technique [0002] Inductors are components that convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but with only one winding. An inductor has a certain inductance, it only resists changes in current flow. Inductors are also called chokes, reactors, and dynamic reactors. At present, the size of the inductor is relatively large, so it will take up a lot of space during installation and use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-current coil inductor to solve the technical problem in the prior art that the inductor occupies a large space during installation and use. [0004] In order to achieve the above purpose, the technical solution adopted in the present invention is to pro...
