[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, which only impedes changes in current. If there is no current flowing through the inductor, it will try to impede the current from flowing through it when the circuit is closed; if there is current flowing through the inductor, it will try to maintain the current when the circuit is open.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] A novel tolerance-modulated integrated magnetic component, such as Figure 1-4 As shown, the system includes a base 1 made of PVC bakelite. A mounting base 3 is symmetrically protruding from the top of the base 1. A reinforcing base 2 is integrally formed and protrudes between the base 1 and the mounting base 3. A magnetic core frame is mounted on the mounting base 3. The magnetic core frame is composed of a first magnetic core frame 6 and a second magnetic core frame 8. The first magnetic core frame 6 has integrally formed side posts and a center post. The first magnetic core frame 6 has an overall E-shaped structure. Coil windings 9 are wound and mounted on the side posts. Lead heads 10 protrude from both ends of the coil windings 9. A through hole 4 is provided on the base 1 for the lead heads 10 to pass through.

[0021] Using a base as a carrier, made of plastic bakelite, and with two sets of mounting seats 3 on its front and rear sides and a core column, its top is divided into two cavities. The first core frame 6, the second core frame 8, and the coil winding 9 are installed there to achieve a balance between common-mode and differential-mode inductance. The first core frame 6 is equipped with side columns and a center column, forming an E-shaped structure. The center column has an adjustable air gap and, as a component of the differential-mode inductance, plays a significant role in balancing the common-mode and differential-mode inductance. The integrated common-mode and differential-mode inductor has a high degree of integration, which can reduce the number of components used, lower production costs, and ensure the performance of its differential-mode inductance, thus improving the practicality of the device.

[0022] Both the first magnetic core frame 6 and the second magnetic core frame 8 are provided with snap-fit ​​grooves 7 for mounting the mounting base 3. Positioning holes 71 are drilled on the inner side of the snap-fit ​​grooves 7, located near the top of the snap-fit ​​grooves 7. Positioning bolts 5 are installed near the top of the mounting base 3, with a threaded fit between the mounting base 3 and the positioning bolts 5. The positioning bolts 5 are also inserted into the positioning holes 71. Through the cooperation between the first magnetic core frame 6, the second magnetic core frame 8, and the mounting base 3, the magnetic components or the base 1 can be easily and quickly disassembled and replaced during subsequent work.

[0023] The first magnetic core frame 6 and the second magnetic core frame 8 are made of high-conductivity manganese-zinc ferrite, and the coil winding 9 is made of enameled wire. The use of flat enameled wire in the coil winding 9 significantly improves the consistency and heat dissipation properties during winding.

[0024] The working principle of this utility model:

[0025] During installation, the coil winding 9 is wound and installed on the side post, and the first magnetic core frame 6 and the second magnetic core frame 8 are fixed together. The snap-fit ​​grooves 7 on the first magnetic core frame 6 and the second magnetic core frame 8 are inserted into the mounting base 3. The positioning bolt 5 is rotated, and the mounting base 3 and the positioning bolt 5 are threaded together, so that the positioning bolt 5 is inserted into the positioning hole 71, thereby completing the overall positioning of the integrated magnetic component.

[0026] The base, serving as the carrier, is made of plastic bakelite. Two sets of mounting seats 3 on its front and rear sides, along with the magnetic core column, divide its top into two cavities. The first magnetic core frame 6, the second magnetic core frame 8, and the coil winding 9 are then installed to achieve a balance between common-mode and differential-mode inductance. The first magnetic core frame 6 has side columns and a center column, forming an E-shaped structure. The center column has an adjustable air gap and serves as a component of the differential-mode inductance. The coil winding 9 uses flat enameled wire, which exhibits excellent consistency and heat dissipation during winding, significantly contributing to the balance between common-mode and differential-mode inductance. The high integration of the common-mode and differential-mode integrated inductors reduces the number of components used, lowers production costs, and ensures the performance of the differential-mode inductance, thus improving the practicality of the device.
