[0021] The bottom plate is made of insulating material, which can prevent current leakage and ensure the safety of the inductor device. The bottom plate comprises a mounting portion for mounting the coil, and the bottom plate is provided with a mounting hole for mounting the bottom plate at a preselected position, and the coil of the inductor device is electrically connected to the PCB board through a lead wire. As shown in the figure, Figure 1 In the inductor device 100 provided in the embodiment, the mounting hole 121 is arranged on the bottom plate 12, and the inductor device 100 provided in the embodiment can be mounted at a preselected position through the mounting hole 121 on the bottom plate 12.

[0022] According to the above description, the inductor device 100 provided in the present application can be mounted in the area close to the PCB board of the equipment through the mounting hole 121 on the bottom plate 12, and the coil of the inductor device is electrically connected to the PCB board through a lead wire. In this way, the influence of the excessively large size of the inductor device on the installation of other parts on the PCB board can be avoided.

[0023] As an optional implementation, in the inductor device 100 provided in the embodiment, the number of mounting holes 121 on the bottom plate 12 is greater than or equal to two, which is used to mount the inductor device 100 on a preselected position.

[0025] As shown in the figure, Figure 3 in the inductor device 100 provided in the embodiment, a mounting portion 122 is further arranged on the surface of the bottom plate 12, the mounting portion 122 includes a first positioning clamping groove 1221 and a second positioning clamping groove 1222, which is used to fix the coil 111.

[0026] As shown in the figure, Figure 3 the first positioning clamping groove 1221 is arranged at the right end of the bottom plate 12, and the second positioning clamping groove 1222 is arranged at the left end of the bottom plate 12, and the second positioning clamping groove 1222 is opposite to the first positioning clamping groove 1221. Further, in combination with Figure 1 and Figure 3 , two triangular-shaped supporting blocks are arranged on the outer side of the first positioning clamping groove 1221 (i.e., the side of the first positioning clamping groove 1221 away from the second positioning clamping groove 1222), which is used to better fix the first positioning clamping groove 1221, and similarly, two triangular-shaped supporting blocks are arranged on the outer side of the second positioning clamping groove 1222 (i.e., the side of the second positioning clamping groove 1222 away from the first positioning clamping groove 1221), which is used to better fix the second positioning clamping groove 1222.

[0027] As shown in the figure, Figure 3 in the inductor device 100 provided in the embodiment, the coil body 11 is fixed around an iron core 112, the first end of the iron core 112 is clamped with the first positioning clamping groove 1221, and the second end of the iron core 112 is clamped with the second positioning clamping groove 1222, so as to fix the coil 111 on the bottom plate 12 through the first positioning clamping groove 1221 and the second positioning clamping groove 1222.

[0028] As shown in the figure, Figure 3As shown, the first positioning slot 1221 and the second positioning slot 1222 have upward openings. When installing the coil 111 on the bottom plate 12, the two ends of the iron core 112 are respectively aligned with the first positioning slot 1221 and the second positioning slot 1222, and then the iron core 112 is pushed downward, so that the two ends of the iron core 112 are clamped in the positioning slots, thereby realizing the installation of the coil 111 on the bottom plate 12, and the installation is convenient.

[0029] Further, as an optional implementation manner, as shown in Figure 3 In the inductor device 100 provided in the embodiment, a limiting groove 123 is further arranged on the surface of the bottom plate 12, and the limiting groove 123 is arranged at a position between the first positioning slot 1221 and the second positioning slot 1222. As shown in Figure 3 The limiting groove 123 can be arranged at a position in the middle of the first positioning slot 1221 and the second positioning slot 1222, and the upper surface of the limiting groove 123 supports the coil 111, thereby avoiding the direct contact between the coil 111 and the bottom plate 12.

[0030] As an optional implementation manner, the inductor device 100 provided in the embodiment further includes two insulating cables 13. As shown in Figure 3 The first end of the first insulating cable 131 is electrically connected to one wire outlet end of the coil body 11, the first end of the second insulating cable 132 is electrically connected to another wire outlet end of the coil body 11, the second end of the first insulating cable 131 is electrically connected to one terminal 14, and the second end of the second insulating cable 132 is electrically connected to another terminal 14. The inductor device 100 is electrically connected to a PCB board through the terminals 14, thereby working.

[0031] As shown in Figure 3 As an optional implementation manner, the terminal 14 has a flat structure, and a through hole is arranged at the center of the terminal 14. By means of the through hole of the terminal 14, one end of a lead wire can be conveniently wound on the terminal 14, and the reliability of the contact between the lead wire and the terminal 14 is ensured.

[0032] As an optional implementation manner, the inductor device 100 provided in the embodiment further includes a supporting block 124 arranged on the surface of the bottom plate 12. As shown in Figure 3 and Figure 4 The supporting block 124 is arranged close to the second positioning slot 1222. In use, the lower wire outlet end of the coil 111 is installed close to the second positioning slot 1222, so that the supporting block 124 can lift the second insulating cable 132, and the second insulating cable 132 is lifted to keep a certain distance from the surface of the bottom plate 12, thereby avoiding the second insulating cable 132 being too close to the bottom plate 12 of the inductor device 100, and playing a waterproof role on the second insulating cable 132.

[0033] As an optional implementation, the inductor device 100 provided in the embodiment further comprises a yellow wax tube. As shown in the figure, the yellow wax tube is wrapped around the connection between the outgoing end of the coil body 11 and the insulated cable 13, and plays an insulating role, and can also prevent animals such as rats from biting the cable. It should be noted that in the inductor device 100 provided in the embodiment, the yellow wax tube is wrapped around the connection between the two insulated cables 13 and the outgoing end of the coil body 11. Figure 1

[0034] As an optional implementation, the inductor device 100 provided in the embodiment further comprises a heat shrink tube. The heat shrink tube is wrapped outside the yellow wax tube arranged at the connection between the outgoing end of the coil body 11 and the insulated cable 13, further playing an insulating role, and can also play a role in preventing corrosion, water and wear.

[0035] Further, as an optional implementation, in the inductor device 100 provided in the embodiment, one end of each of the two insulated cables 13 connected with the terminal 14 can also be wrapped with a heat shrink tube, which is used to fix the connection between the insulated cable 13 and the terminal 14, and further plays an insulating protection role.

[0036] The inductor device 10 provided in the present application is suitable for occasions where the inductor has a large volume. As an optional implementation, the inductor device 10 provided in the embodiment can be a plain wave reactor. According to the structure of the inductor device 10 provided in the present application, the area occupied during installation is small, which can effectively avoid affecting the installation of other parts on the PCB of the device.

[0037] According to the above description, the inductor device 100 provided in the present application can be installed on the device by using bolts through the installation hole 121 provided on the bottom plate 12, which reduces the installation area of the inductor device 100 on the device and avoids affecting the installation of other parts on the device; and the yellow wax tube and the heat shrink tube are also provided on the insulated cable 13 to improve the insulation protection of the inductor device 100.
