Transformer and magnetic core structure thereof

Abstract

The invention discloses a transformer and a magnetic core structure thereof. The magnetic core structure comprises a first side post, a second side post, an annular space, a middle post and a base, wherein the first side post is provided with a first side post inner wall; the second side post is opposite to the first side post and is provided with a second side post inner wall; the annular space is enclosed by the first side post inner wall and the second side post inner wall and is provided with a first central point, a first opening and a second opening; the two openings are opposite to each other and are formed between the first side post and the second side post; the middle post is arranged in the annular space and is provided with a second central point; the second central point is arranged between the first central point and any one of the two opposite openings; and the base is arranged at the bottom of the annular space and is connected with the first side post, the second side post and the middle post. Therefore, the magnetic core structure can be designed according to the requirements on coil winding and the like so as to fully utilize the space of a magnetic core window, and the volume of the magnetic core structure and the transformer is reduced further.

Description

technical field [0001] The invention relates to a magnetic core structure, in particular to a magnetic core structure that can be applied to a transformer to increase the utilization rate of the magnetic core window, thereby reducing the volume of the magnetic core structure and the transformer and facilitating design changes. Background technique [0002] Magnetic components, such as transformers and inductors, are indispensable and necessary components for various power supply devices, and are critical to the success of power supply designs. For magnetic components to achieve various design purposes, the correct design and manufacture of the magnetic core structure is even more important. [0003] see Figure 1A and figure 2 B, it is a schematic front view and top view of a conventional magnetic core structure. that is, Figure 1A As shown, it shows an existing PJ core structure, and another example Figure 1B As shown, the PJ-shaped magnetic core structure 10 mainly i...

Problems solved by technology

[0005] Therefore, the above-mentioned existing magnetic core structure is not flexible, and its window utilization rate is not ideal according to different design schemes, resulting in an increase in the volume of the magnetic element and an increase in cost, and it cannot adapt to various design purposes. Restricts the design scheme, thereby affecting the freedom of design arrangement of other components in the electronic device
