Embodiment Construction

[0046] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0047] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "front", "rear", "circumferential" and...

Abstract

The invention relates to the technical field of electronic components, and particularly discloses a magnetic element and a preparation method thereof. The magnetic element includes a columnar magneticcore, a wire, and a magnetic body. The wire is provided with a coil section wound at the periphery of the columnar magnetic core and a connecting section led out from the end part of the coil section; the magnetic body at least wraps the columnar magnetic core and the coil section of the wire, and the connecting section of the wire is at least partially exposed out of the magnetic body. The arrangement of the columnar magnetic core effectively increases the magnetic field density of the center of the coil section and is beneficial to ensure that the magnetic performance of the magnetic element is optimized. The magnetic core is arranged to be columnar, so that the winding of the coil section is facilitated. Furthermore, the connecting section does not need to be connected with a lead frame; therefore, the position of the connecting section is not limited by the lead frame, that is, the end part of the coil section can be not limited by the lead frame, the coil section can be set to the actually required size, and the coil section can be set to the maximum extent, so that the magnetic performance of the magnetic element is further improved, and the effect of optimizing the energy conversion and storage performance of the magnetic element is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a magnetic component and a preparation method thereof. Background technique [0002] In the field of electronic technology, magnetic components are the core components of energy conversion and storage, and their performance is related to the efficiency and performance of the entire system. Magnetic components mainly include inductors and transformers. Among them, taking inductors as an example, inductors are components that can convert electrical energy into magnetic energy and store them, also known as chokes, reactors or dynamic reactors. [0003] The manufacturing process of the existing inductor is usually to weld the inner end and the outer end of the air-core coil to the two different connection ends on the lead frame respectively, and then inject the powder molding material in a way to completely surround the air-core coil In the mold, it is pressed through ...
