Problems solved by technology

However, due to the support and expansion of the coil during molding, the density inside the magnetic core is relatively low, which is not conducive to the improvement of the inductance of the magnetic core; and because of molding and extrusion, the coil is easily deformed and skewed in the powder, which affects product reliability and characteristics. are disadvantageous

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0042] Meanwhile, the drawings and descriptions of the embodiments are illustrative rather than restrictive. Like reference numerals refer to like elements throughout the specification. In addition, for understanding and ease of description, the sizes of some structures, regions, etc. may be exaggerated in the drawings. Additionally, the word "comprise" and variations such as "comprising" or "having" will be understood to imply the inclusion of that element, but not the exclusion of any other element, unless expl...

Abstract

The invention discloses an inductor and a manufacturing method thereof. The inductor includes: a magnetic core body and a winding body, the magnetic core body includes a preformed part and a processed part; wherein the preformed part includes a first support structure and a second support structure arranged on top of the first support structure, the first support A space is formed between the structure and the second support structure, and the first support structure has a first protrusion in the space, and the first protrusion is used to nest the winding body; the processing part is the preformed part that will nest the winding body It is made by hot pressing after being placed in the mold cavity and adding powder. The solution provided by the invention can increase the density of the magnetic core body, prevent the deformation and displacement of the winding body during the manufacturing process, and improve the performance of the inductor.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic equipment, in particular to an inductor and a manufacturing method thereof. Background technique [0002] Inductors (also known as chokes, reactors, and dynamic reactors) are components that can convert electrical energy into magnetic energy and store it. Its construction is similar to a transformer, but with only one winding. In a state where no current is flowing, the inductor will try to block the flow of current when the circuit is on; while in a state where current is passing, the inductor will try to maintain the current flow when the circuit is off. [0003] The one-piece inductor is usually die-cast by embedding the coil inside the metal magnetic powder. Compared with the traditional inductor, the one-piece inductor has higher inductance and smaller leakage inductance. However, due to the support and expansion of the coil during molding, the density inside the magnetic cor...
