[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Refer to the attached Figure 1 and attached Figure 3 The utility model provides an embodiment: an integrated inductor structure, including a magnetic core 1, a magnetic core 2, and a magnetic core 3, a magnetic core 4 is provided on the left side of the magnetic core 3, a connecting column 5 is fixedly connected to the right side of the magnetic core 1, the magnetic core 2, and the magnetic core 3, and the outer walls of multiple connecting columns 5 are fixedly connected with high-temperature tape 6, the right sides of the magnetic core 1, the magnetic core 2, and the magnetic core 3 are fixedly connected with a middle column 7, the right sides of multiple middle columns 7 are slidably connected with a skeleton 8, the outer walls of multiple skeletons 8 are provided with a Mylar wire 9, and the right side of the right skeleton 8 is slidably connected to the left side of the magnetic core 4; the Mylar wire 9 is wound into a coil state by an automated winding equipment; the multiple skeletons 8 are made of NOMEX material, which has good insulation performance and mechanical strength, can effectively protect the Mylar wire 9, and reduce safety hazards such as short circuit caused by wire damage;

[0032] Specifically, four magnetic cores are combined into a structure of three groups of inductors. Compared with traditional discrete inductor components, three groups of independent inductors require six magnetic cores. Using this integrated method, only four magnetic cores are needed to meet the product characteristics requirements, which improves the space utilization of the circuit board, makes the circuit board design more simple and efficient, and can greatly reduce the overall volume. This is very important for the continuous pursuit of miniaturization and lightness of modern electronic equipment. It can make the design of the device more compact and leave more space for other components. The Mylar wire 9 is wound into a coil state by an automated winding device. The winding is performed by the automated device, which is much easier than the traditional manual winding method. This greatly improves production efficiency, enabling rapid, mass production to meet the needs of large-scale production. The bobbin 8 is made of NOMEX material and serves to isolate the Mylar wire 9 and the core center column 7, preventing damage during product assembly, thereby improving product safety and reliability. Magnetic core 1, magnetic core 2, magnetic core 3, and magnetic core 4 are stacked and combined in order from left to right to form an integrated structure of three groups of inductors. This combination has the characteristic of low inductance deviation, ensuring the accuracy and stability of the inductance value. The deviation of the inductance value is small, which can meet the circuit design requirements for high inductance precision.

[0033] Refer to the attached Figure 2 The bottoms of magnetic cores 1, 2, 3, and 4 are slidably connected to a common base 10. A positioning hole 13 is provided at the bottom of the base 10. One end of the outer wall of the Mylar wire 9 is slidably connected to the inner side of the corresponding positioning hole 13. The Mylar wire 9 is fixed to the positioning hole 13 by glue dispensing, which enhances the connection stability between the Mylar wire 9 and the base 10.

[0034] Specifically, a positioning hole 13 is provided at the bottom of the base 10, and one end of the outer wall of the Mylar wire 9 is slidably connected to the inner side of the corresponding positioning hole 13, so that the Mylar wire 9 can be accurately positioned on the base 10, ensuring the regularity and consistency of the internal structure of the inductor. The lead wire of the Mylar wire 9 is passed through the predetermined positioning hole 13 of the base 10, and the lead wire is fixed to the base 10 as a whole by gluing. The gluing fixation not only enhances the connection stability between the Mylar wire 9 and the base 10, but also prevents the Mylar wire 9 from being displaced or loosened due to external forces or vibrations during use, thereby ensuring the stability and reliability of the electrical performance of the inductor.

[0035] Refer to the attached Figure 4 The four corners of the top of the base 10 are fixedly connected with support columns 12; the front and rear sides of the top of the base 10 are fixedly connected with lifting columns 14; the top of the base 10 is provided with a plurality of through holes 11. The base 10 increases the heat dissipation capacity of the product by raising the support columns 12 and the through holes 11;

[0036] Specifically, the base 10 forms a certain space gap between the inductor as a whole and the mounting plane by raising the support column 12. This gap increases the air circulation channel at the bottom of the inductor, which is conducive to heat dissipation. The provision of the through hole 11 further promotes air circulation. The support column 12 and the raising column 14 raise the inductor, reducing the contact area between the inductor and the mounting plane, and reducing the resistance to heat conduction through the mounting plane.

[0037] Working Principle: Mylar wire 9 is wound into a coil using automated equipment. NOMEX is formed into a bobbin 8 using a winding jig. The bobbin 8 is assembled onto the core center column 7. The coil is then assembled onto the bobbin 8. The assembly is completed using high-temperature tape 6 on the connecting column 5. The four cores are now combined into an integrated structure of three inductors. Core 1 1, Core 2 2, Core 3 3, and Core 4 4 ​​are stacked and combined in order from left to right, resulting in a low inductance deviation.

[0038] The four magnetic cores are assembled by the high-temperature tape 6 on the connecting column 5, and the bottom thereof is fixed to the base 10. The lead wires of the Mylar wire 9 are passed through the predetermined positioning holes 13 of the base 10. The lead wires are fixed to the base 10 as a whole by gluing, and the base 10 is fixed to the four magnetic cores as a whole.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
