[0004] Inductor is an electronic component widely used in electronic equipment. It is an energy storage component. Traditional inductors wind enameled wires on the magnetic core, so that the inductor has a fixed number of coil turns and a fixed core length. After the two ends of the enameled wire are connected to the circuit and energized, the magnetic flux generated by the inductance is constant, and the stored energy is also constant. With the continuous upgrading of electronic products, some electronic devices require Change the size of the magnetic flux of the inductor to adapt to the different energy requirements of different electronic components. Therefore, installing an inductor with a fixed magnetic flux in the circuit board can no longer meet the needs of increasingly advanced electronic products. An inductor that can change the size of the magnetic flux Urgent need to be developed

Embodiment Construction
[0028] like figure 1 , figure 2 , image 3 and Figure 4 , a variable plastic package inductor, including a plastic case 3, a plastic plate 4, a regulator, a magnetic core 1 and a coil 2 wound on the magnetic core. The plastic shell 3 is connected to the plastic plate 4 and forms a closed space with the plastic plate 4. The plastic shell 3 and the plastic plate 4 are made of ABS plastic, which has good heat resistance. Able to withstand the heat dissipated from the inductor during normal operation. The magnetic core 1 is placed in the closed space and installed on the plastic plate 4, the magnetic core 1 is provided with threads and the surface is coated with a layer of insulating material, the pitch and the height of the threads of the threads are the same as The diameters of the coils 2 are consistent. The coils 2 are bare wires and are wound on the magnetic core 1 along the pitch so that the surface of the magnetic core 1 is smooth. The adjuster is located in the encl...
