Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0026] Such as Figure 1 to Figure 8 An integrated high-frequency magnetic element shown includes a base 1, a first magnetic element, a second magnetic element, and a cover structure. The first magnetic element includes two sets of first magnetic cores 2, a first coil 3 wound on the first magnetic cores 2, and a U-shaped vertical plate 4. The first magnetic cores 2 It is arranged inside the vertical plate 4 , and it should be noted that an extended protective plate 5 is provided at the head of the vertical plate 4 . The second magnetic element includes an annular second magnetic core 6 and a second coil 7 wound on the second magnetic core 6 .

[0027] The base 1 includes a first mounting portion 8 and a second mounting portion 9 snapped to the first mounting portion 8, the f...

Abstract

The invention discloses an integrated high-frequency magnetic element. The magnetic element comprises a base, a first magnetic element and a second magnetic element and further comprises a sealing cover structure, the base comprises a first mounting part and a second mounting part clamped with the first mounting part, and the sealing cover structure comprises an L-shaped first cover plate and a square second cover plate. A through hole is formed in the base, and welding pins penetrating through the through hole are arranged on the first cover plate and the second cover plate. The welding difficulty of the magnetic element is greatly reduced, and time and labor are saved; meanwhile, the first magnetic element and the second magnetic element are compact in structure, the welding area is saved, and the requirement for high power density is met; and the base comprises the first mounting part and the second mounting part which are spliced together, so that the base can be separately operated and also can be jointly mounted, and the universality is high.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an integrated high-frequency magnetic element. Background technique [0002] With the requirement of high power density power conversion power supply, the volume of magnetic components is required to be more miniaturized. In a complete switching power supply, at least one inductor and at least one transformer are often required to achieve the purpose of multiple outputs. [0003] The inductor and transformer in the traditional switching power supply are independent components, which need to be welded separately in the switching power supply. Due to the small size of these magnetic components, it is difficult to weld them, and the area occupied by separate welding is large, which limits the high power density requirements. Contents of the invention [0004] The object of the present invention is to provide an integrated high-frequency magnetic element aiming at the shortc...
