[0002] Currently, magnetic devices are widely used in new energy, charging piles, photovoltaic and energy storage inverters, and high-power power supplies. Integrated design is gaining increasing attention as these fields develop, due to its advantages such as reducing the overall size and weight of the system, enhancing system reliability and safety, and reducing manufacturing and maintenance costs. Magnetic devices also need to be integrated and developed accordingly.
[0003] Currently, conventional transformers and resonant inductors in magnetic devices are large in size and weight, which is not conducive to the layout of power supply components and cannot match the miniaturized and compact design of terminal products. Moreover, the overall layout of magnetic components such as transformers and resonant inductors has a large number of pins and connection points, which is not conducive to the integration of magnetic component modules into the end user. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetic module that integrates two or more discrete magnetic components together, thereby reducing volume and weight, reducing the number of leads, and lowering losses and conversion efficiency.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A magnetic module includes a housing and a magnetic assembly. The housing has an internal accommodating cavity. The magnetic assembly includes multiple magnetic elements and multiple magnetic cores. Each magnetic element is wound around two magnetic cores. The multiple magnetic elements are connected in a predetermined connection method and arrangement to form a module. One end of the module has an input pin, and the other end of the module has an output pin. The magnetic assembly is detachably housed in the accommodating cavity. The left and right sides of the accommodating cavity have accommodating openings. The input pin and the output pin extend out of the accommodating cavity through the accommodating openings. Each input pin and the output pin is connected to a terminal.
[0007] Preferably, the outer shell is made of aluminum.
[0008] Furthermore, the predetermined connection method is a series connection, a parallel connection, or a hybrid connection.
[0009] Furthermore, the magnetic element is a resonant inductor or a transformer.
[0010] Furthermore, the magnetic element is coated with a film-coated square copper wire.
[0011] Furthermore, UL heat shrink tubing is provided on the input pins and output pins.
[0012] Furthermore, the output pin grouping design.

The magnetic frame includes two opposing frames, which are connected to the bottom of the magnetic central column through the connecting part. The two frames enclose a semi-enclosed accommodating space.
[0014] Furthermore, the magnetic element is wound on the outer surface of the Nomi paper tape, and the inner side of the Nomi paper tape is surrounded by a column hole that matches the magnetic central column.
[0015] Furthermore, the upper and lower parts of the column hole are each sleeved with the magnetic central column of one of the magnetic cores, and the magnetic element is housed within the accommodating space.
[0016] This invention integrates multiple magnetic components in a predetermined manner, simplifying previously separate magnetic component circuits into a single module, reducing the number of pins. Furthermore, the magnetic components are rationally arranged within a single housing, further reducing the overall size of the module, lowering manufacturing and maintenance costs, and enhancing system reliability and safety compared to conventional designs. This invention, through its integrated structure design of separate magnetic components, effectively saves product size while meeting reliability and safety requirements, thus facilitating the miniaturization of power supply products.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] See Figures 1 to 3 The magnetic module includes a housing 1 and a magnetic assembly. The housing has an internal cavity 11. The magnetic assembly includes multiple magnetic elements 2 and multiple magnetic cores 3. Each magnetic element 2 is wound around two magnetic cores 3. The multiple magnetic elements 2 are connected in a predetermined connection method and arrangement order to form a module. One end of the module has an input pin 21 and the other end has an output pin 22. The input pin 21 and the output pin 22 are each connected to a terminal 4. The magnetic module is housed in the cavity 11. The cavity 11 has accommodating openings 12 on its left and right sides. The input pin 21 and the output pin 22 extend out of the cavity 11 through the accommodating openings 12.
[0026] This embodiment integrates multiple magnetic components 2 in a predetermined manner, thereby simplifying the originally discrete circuits of multiple magnetic components 2 into a single module, reducing the number of pins. Simultaneously, the magnetic components 2 are housed within a single housing 1 through a rational layout design, further reducing the overall size of the module, lowering manufacturing and maintenance costs, and enhancing system reliability and safety compared to conventional designs. This invention, through the integrated structure design of multiple discrete magnetic components 1, effectively saves product size while meeting reliability and safety requirements, thus facilitating product miniaturization.
[0027] In this embodiment, the outer shell 1 is made of aluminum, which can better dissipate heat from the magnetic components during use.
[0028] The magnetic element 2 can be a resonant inductor or a transformer. The predetermined connection method can be series connection, parallel connection or mixed connection, and the arrangement order can be sequential arrangement or array arrangement. In this embodiment, there are two magnetic elements 2, one is a transformer and the other is a resonant inductor. The two magnetic elements 2 are arranged sequentially and integrated in series, and are installed in the aluminum shell 1.
[0029] In this embodiment, the magnetic element 2 is covered with a film-coated square copper wire. The high power and high temperature resistance of the film-coated square copper wire enable it to adapt to high frequency conduction and high current load operation, thereby improving the electrical performance of the magnetic element. Its small size also saves more space, making the layout of the magnetic element more compact.
[0030] In this embodiment, UL heat shrink tubing 23 is provided on the input pin 21 and the output pin 22.
[0031] After the magnetic component 2 is integrated, the configuration of its output pins will be affected by the degree of integration. If the degree of integration is high, multiple functional magnetic components are tightly integrated together. In order to facilitate signal transmission and management, the output pins 22 need to be grouped and configured according to different functional modules.
[0032] In this embodiment, the magnetic core 3 includes a magnetic center post 31, a magnetic frame 32, and a connecting portion 33. The magnetic frame 32 includes two opposing frames, which are connected to the bottom of the magnetic center post 31 via the connecting portion 33. The two frames 32 enclose a semi-enclosed accommodating space. The magnetic element 2 is wound on the outer surface of the Nomi paper tape 5. The Nomi paper tape has high insulation performance and mechanical strength, which can effectively prevent current leakage and short circuit, protect the circuit safety of the magnetic element, and provide additional support and protection for the magnetic element skeleton. The inner side of the Nomi paper tape 4 is surrounded by post holes 51 that match the magnetic center post 31. The upper and lower parts of the post holes 51 are fitted with the magnetic center post 31 of one magnetic core 3, and the magnetic element is accommodated in the accommodating space.
[0033] With this design, the cylindrical holes 51 formed by the inner side of the Nomi paper tape 5 are fitted with the two magnetic cores 31, which can better fix the magnetic element 2, ensure the position and stability of the magnetic element 2 on the magnetic core 31, and prevent displacement or falling off under vibration or impact. On the other hand, since the Nomi paper tape 5 has good thermal conductivity, its tight fit on the magnetic core core 31 can help the magnetic core 31 dissipate heat better.
[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
