Description

Technical Field

[0001] This invention relates to the field of magnetic core design technology, and in particular to a magnetic core structure. Background Technology

[0002] In high-frequency circuits, transformers are often used in circuit design. However, in design fields such as automotive, the required transformers generally have higher performance requirements, and the required magnetic cores are also larger to meet the performance requirements.

[0003] In existing technologies, magnetic cores are generally manufactured using a one-piece molding technique or by stacking multiple flat magnetic blocks. However, for such large magnetic cores, the one-piece molding method makes demolding difficult and can easily damage the magnetic core during demolding, resulting in wasted costs. On the other hand, while stacking multiple flat magnetic blocks can reduce the chance of damage to the magnetic core, it requires more time to assemble the magnetic blocks into the core, affecting the efficiency of transformer manufacturing and increasing time costs. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a magnetic core structure that is easy to manufacture, reduces manufacturing losses, and is easy to assemble into a magnetic core, thereby improving the manufacturing efficiency of transformers.

[0005] A magnetic core structure according to a first aspect of the present invention includes: a first integrally molded magnetic component and a second integrally molded magnetic component. The first integrally molded magnetic component includes a first central post, a first connecting portion, and a first side post. One side of the first connecting portion is connected to one side of the first central post, and the other side of the first connecting portion is connected to the first side post. The first central post and the first side post are parallel to each other. The second integrally molded magnetic component includes a second central post, a second connecting portion, and a second side post. One side of the second connecting portion is connected to one side of the second central post, and the other side of the second connecting portion is connected to the second side post. The second central post and the second side post are parallel to each other. The first integrally molded magnetic component and the second integrally molded magnetic component are attached to each other through the other side of the first central post and the other side of the second central post to form a magnetic core. The first central post and the second central post are parallel to each other.

[0006] A magnetic core structure according to an embodiment of the present invention has at least the following beneficial effects:

[0007] This utility model discloses a magnetic core structure, comprising a first integrally molded magnetic component and a second integrally molded magnetic component. The first integrally molded magnetic component includes a first central post, a first connecting portion, and a first side post. One side of the first connecting portion is connected to one side of the first central post, and the other side of the first connecting portion is connected to the first side post. The first central post and the first side post are parallel to each other. The second integrally molded magnetic component includes a second central post, a second connecting portion, and a second side post. One side of the second connecting portion is connected to one side of the second central post, and the other side of the second connecting portion is connected to the second side post. The second central post and the second side post are parallel to each other. The parallel arrangement divides the magnetic core into two parts: the first integrally molded magnetic component and the second integrally molded magnetic component. Compared to an integrally molded magnetic core, this design is easier to manufacture by casting and reduces the chance of re-damage during the casting process. Furthermore, if either the first or second integrally molded magnetic component is damaged, only the corresponding part needs to be scrapped, saving costs. The first and second integrally molded magnetic components are joined together by the other side of the first central pillar to form the magnetic core. Compared to the process of stacking multiple flat magnetic blocks to form the magnetic core, the assembly process is simpler and more efficient.

[0008] According to some embodiments of the present invention, the first central column can be a cuboid, a semi-cylinder, or a semi-elliptical cylinder, and the second central column can be a cuboid, a semi-cylinder, or a semi-elliptical cylinder.

[0009] According to some embodiments of the present invention, the first central column and the second central column can adopt different shapes.

[0010] According to some embodiments of the present invention, the first connecting part and the second connecting part can use magnetic blocks of different shapes.

[0011] According to some embodiments of the present invention, the first connecting part and the second connecting part can use magnetic blocks of different lengths.

[0012] According to some embodiments of the present invention, the first central column and the first connecting portion are perpendicular to each other.

[0013] According to some embodiments of the present invention, the second central column and the second connecting part are perpendicular to each other.

[0025] like Figure 1-4 As shown, a magnetic core structure according to a first aspect embodiment of the present invention includes a first integrally molded magnetic component 100 and a second integrally molded magnetic component 200. The first integrally molded magnetic component 100 includes a first central post 110, a first connecting portion 120, and a first side post 130. One side of the first connecting portion 120 is connected to one side of the first central post 110, and the other side of the first connecting portion 120 is connected to the first side post 130. The first central post 110 and the first side post 130 are parallel to each other. The second integrally molded magnetic component 200... 00 includes a second central column 210, a second connecting portion 220, and a second side column 230. One side of the second connecting portion 220 is connected to one side of the second central column 210, and the other side of the second connecting portion 220 is connected to the second side column 230. The second central column 210 and the second side column 230 are parallel to each other. The first integrally formed magnetic component 100 and the second integrally formed magnetic component 200 are attached to the other side of the first central column 110 and the other side of the second central column 210 to form a magnetic core. The first central column 110 and the second central column 210 are parallel to each other.

[0026] like Figure 3 As shown, in some embodiments of this utility model, the first central column 110 can be a cuboid, a semi-cylinder, or a semi-elliptical cylinder, and the second central column 210 can be a cuboid, a semi-cylinder, or a semi-elliptical cylinder, so that the magnetic core formed by the combination can adapt to the skeleton of various conventional magnetic core windows, thereby enhancing its practicality.

[0027] like Figure 3 As shown, in some embodiments of this utility model, the first central column 110 and the second central column 210 can adopt different shapes, thereby enabling the magnetic core to adapt to the skeleton with irregular magnetic core windows, expanding the design types of transformers, and facilitating the testing of transformer designs. Moreover, by designing with a conventionally designed first central column 110 and a conventional but different second central column 210, various transformers can be designed without customizing new magnetic cores, reducing upfront costs. Furthermore, magnetic cores that fail to design can be re-divided into a first integrated molded magnetic component 100 and a second integrated molded magnetic component 200, and combined with the same type of integrated molded magnetic component to form a conventional magnetic core, thereby reducing waste.

[0028] like Figure 4 As shown, in some embodiments of this utility model, the first connecting part 120 and the second connecting part 220 can use magnetic blocks of different shapes to adapt to transformer frames of different shapes.

[0029] like Figure 4 As shown, in some embodiments of this utility model, the first connecting part 120 and the second connecting part 220 can use magnetic blocks of different lengths to adapt to transformer frames of different shapes.

[0030] like Figure 1 , 2 As shown, in some embodiments of this utility model, the first central column 110 and the first connecting portion 120 are perpendicular to each other.

[0031] like Figure 1 , 2 As shown, in some embodiments of this utility model, the second central column 210 and the second connecting portion 220 are perpendicular to each other.

[0032] This utility model discloses a magnetic core structure, including a first integrally molded magnetic component 100 and a second integrally molded magnetic component 200. The first integrally molded magnetic component 100 includes a first central post 110, a first connecting portion 120, and a first side post 130. One side of the first connecting portion 120 is connected to one side of the first central post 110, and the other side of the first connecting portion 120 is connected to the first side post 130. The first central post 110 and the first side post 130 are parallel to each other. The second integrally molded magnetic component 200 includes a second central post 210, a second connecting portion 220, and a second side post 230. One side of the second connecting portion 220 is connected to one side of the second central post 210, and the other side of the second connecting portion 220 is connected to the second side post 230. With zero connection, the second central column 210 and the second side column 230 are parallel to each other, thus dividing the magnetic core into two parts: the first integrally molded magnetic component 100 and the second integrally molded magnetic component 200. Compared with the integrally molded magnetic core, it is easier to mold and reduce the probability of re-loss during the molding process. If the first integrally molded magnetic component 100 or the second integrally molded magnetic component 200 is damaged, only the corresponding part needs to be scrapped, saving costs. Furthermore, the first integrally molded magnetic component 100 and the second integrally molded magnetic component 200 are connected to form the magnetic core by attaching the other side of the first central column 110 and the other side of the second central column 210. Compared with the process of stacking multiple flat magnetic blocks to form the magnetic core, the assembly process is also simpler and more efficient.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
