The utility model is provided with a first functional layer comprising a nickel-zinc magnetic ring layer and a ferrite core layer, wherein the nickel-zinc magnetic ring layer has good magnetic effect and anti-interference effect, and the ferrite core layer can effectively suppress the passage of high-frequency interference signals, further improving the anti-interference effect. Through the coordination of the above structures, the problem that the existing magnetic ring inductor has an unsatisfactory anti-interference effect, thereby being inconvenient for people to use, is solved.

[0032] Reference Figure 1 As shown, the utility model provides a technical solution: a magnetic ring inductor, comprising a magnetic ring inductor body 1, the outside of the magnetic ring inductor body 1 is slidably connected to a fixing device 2, and a rotating device 3 is provided on one side of the arc block 206.

[0033] The specific configuration and functions of the fixing device 2 and the rotating device 3 will be described in detail below.

[0034] Reference Figure 2 and Figure 3 As shown, in this embodiment: the fixing device 2 includes a placement seat 201, one side of the placement seat 201 is slidably connected to the magnetic ring inductor coil body 1, a square groove 211 is opened on one side of the placement seat 201, the inner side of the square groove 211 is fixedly connected to a fixing block 202, both sides of the fixing block 202 are fixedly connected to a telescopic rod 203, the output end of the telescopic rod 203 is fixedly connected to a movable plate 205, one side of the movable plate 205 is fixedly connected to an arc block 206, one side of the two arc blocks 206 is slidably connected to the magnetic ring inductor coil body 1, one side of the placement seat 201 is fixedly connected to an I-shaped plate 209, one side of the I-shaped plate 209 is fixedly connected to two pins 210, and one end of the two pins 210 is fixedly connected to the magnetic ring inductor coil body 1. After the movable plate 205 is pulled and the movable plate 205 drives the telescopic rod 203 to its maximum output, the magnetic ring inductor coil body 1 can be placed on the placement seat 201. After the placement is completed, the movable plate 205 is pushed to cause the telescopic rod 203 to retract to its maximum. During the movement of the movable plate 205, the arc block 206 contacts the magnetic ring inductor coil body 1 to form a limiting and fixed effect. The arc surface of the telescopic rod 203 is covered with a spring 204, and the two ends of the spring 204 are respectively fixedly connected to the fixed block 202 and the movable plate 205. The telescopic rod 203 prevents the spring 204 from deforming during the extension or contraction process. An L-shaped plate 207 is fixedly connected to one side of the movable plate 205, and an anti-slip pad 208 is fixedly connected to the outside of the L-shaped plate 207. The movement of the L-shaped plate 207 drives the movement of the movable plate 205.

[0035] Reference Figure 4 As shown, in this embodiment, the rotating device 3 includes a fixed rod 31, one end of which is fixedly connected to the arc block 206. An internally threaded hole 32 is defined at one end of the fixed rod 31. The internal threads of the internally threaded hole 32 connect to a screw rod 33, one end of which is fixedly connected to a rotating block 34. The rotating block 34 rotates, driving the screw rod 33 within the internally threaded hole 32. The rotating block 34 is provided with a plurality of anti-skid grooves 38, evenly distributed on the rotating block 34. These grooves increase friction. One end of the rotating block 34 is fixedly connected to a support rod 35, one end of which is slidably connected to the magnetic ring inductor body 1. This ensures that the movement of the rotating block 34 drives the movement of the support rods 35. Two round rods 36 are fixedly connected to one end of the rotating block 34. The movement of the rotating block 34 drives the movement of the round rods 36. One end of the two round rods 36 is fixedly connected to a limit ring 37, and the inner side of the limit ring 37 is rotatably connected to the fixed rod 31. The limit ring 37 moves on the fixed rod 31 to drive the round rod 36 to move.

[0036] Working principle: When the magnetic ring inductor needs to be installed through the fixing device 2, the operator first passes the pin 210 through the mounting hole opened on the circuit board, and applies glue to the bottom end of the I-shaped plate 209. As the pin 210 is installed, the I-shaped plate 209 contacts the end surface of the circuit board to form a fixed I-shaped plate 209. Then, the movable plate 205 is pulled. After the movable plate 205 drives the telescopic rod 203 to the maximum output, the magnetic ring inductor body 1 can be placed on the placement seat 201. The placement is completed. After that, the movable plate 205 is pushed to retract the telescopic rod 203 to the maximum extent. During the movement of the movable plate 205, the arc block 206 contacts the magnetic ring inductor body 1 to form a limit fixation, and the coil of the magnetic ring inductor and the pin 210 can be soldered to complete the installation. The fixing device 2 solves the problem of a traditional magnetic ring inductor directly bonded to the circuit board. When the circuit board is in a working condition with large vibration, the magnetic ring inductor will become loose and fall off, resulting in poor installation reliability.

[0037] By using the rotating device 3, when it is necessary to prevent the magnetic ring from tilting after the magnetic ring inductor coil is installed, the operator first installs the magnetic ring inductor coil and rotates the rotating block 34. The rotating block 34 drives the screw 33 to rotate. At this time, the position of the screw 33 can be adjusted to make the support rod 35 contact the magnetic ring inductor coil body 1, thereby limiting the support of the magnetic ring inductor coil. By using the rotating device 3, the problem of the traditional magnetic ring inductor coil that the magnetic ring is prone to tilting after the magnetic ring inductor coil is installed is solved.
