[0002] Resonance refers to the resonance of the inductance and capacitance in a circuit containing resistance, inductance and capacitance when the current or voltage in the circuit reaches a certain value, thereby generating a specific resonant frequency. The resonance phenomenon is widely used in filtering, frequency selection, amplification and other circuits. Among them, the inductor is a component that can convert electrical energy into magnetic energy and store it. It is also called a choke, reactor, and dynamic reactor.

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] In order to solve the inconvenience of the coil of the inductor, which is usually wound on a magnetic core or an iron core, when the winding of the coil becomes loose, it often causes the longitudinal length of the coil winding to change and the number of winding turns to change, thereby causing the inductance of the coil to change, requiring partial or full rewinding, such as Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided: A high-frequency and high-power resonant inductor comprises a first frame 1, a second frame 2, an iron core 3 fixedly connected between the first frame 1 and the second frame 2, and a coil 4 wound on the outer wall of the iron core 3. When a constant current flows through the coil 4, a static magnetic field is formed according to the right-hand screw rule, and an alternating current flows through the inductor, an alternating magnetic field is generated, and the changing magnetic field generates an electric field, and an induced electromotive force is generated on the coil 4, generating an induced current. A winding assembly 5 is fixedly connected between the first frame 1 and the second frame 2. When the wound coil 4 is accidentally loosened, it is rewound and compressed by the winding assembly 5, and the maintenance personnel do not need to remove the inductor for operation, and the operation is relatively convenient. The wire assembly 5 is arranged on the outer ring of the coil 4, and one end of the winding assembly 5 is tightly against the coil 4. A switching assembly 6 is rotatably connected between the first skeleton 1 and the second skeleton 2. The switching assembly 6 is arranged on the outer ring of the winding assembly 5. When it is necessary to reduce electromagnetic interference to external devices, the shielding cover is partially closed by the switching assembly 6. When it is used in situations where the shielding cover is not needed, the shielding cover is partially opened by the switching assembly 6 to enhance the internal heat dissipation of the inductor. The outer walls of the first skeleton 1 and the second skeleton 2 are fixedly connected with a protective assembly 7 and a connector 8. The protective assembly 7 is used to cut off the circuit connection when the inductor is damaged, resulting in excessive current and abnormal heating, so as to avoid circuit fire.

[0020] When the inductor is less susceptible to external interference, the switching component 6 is operated to partially open the shielding cover of the inductor to improve the internal heat dissipation efficiency of the inductor. When it is necessary to reduce the electromagnetic interference of the inductor to the outside world, the shielding cover of the inductor is partially closed by operating the switching component 6, so that it can be flexibly adjusted according to different usage scenarios, and has a wide applicability. At the same time, when switching between the inductor without the shielding cover and the inductor with the shielding cover, there is no need to remove the original inductor, and the operation is relatively convenient. During use, when the coil 4 wound on the outer wall of the iron core 3 becomes loose, the longitudinal length of the coil 4 and the number of winding turns will change, and partial or full rewinding will be required. At this time, the winding component 5 can be used to rewind and compact the coil 4 along the original winding trajectory, thereby avoiding changes in the inductance of the coil 4 due to the loosening of the coil 4.

[0021] When the inductor is damaged, it affects the normal operation of the circuit. At the same time, its resistance value increases, resulting in excessive current, which in turn causes abnormal heating of the circuit and even causes the circuit to catch fire, posing certain safety hazards. At this time, the connected circuit is disconnected by the protective component 7, thereby preventing further damage to other devices in the circuit and increasing its safety during use.

[0022] The winding assembly 5 includes a plurality of fixed plates 51 fixedly connected to the side walls of the first skeleton 1 and the second skeleton 2. The plurality of fixed plates 51 are arranged in a circular array on the outer circle of the coil 4. A spiral guide rail 52 is fixedly connected to the outer wall of one side of the plurality of fixed plates 51 close to the coil 4. The spiral guide rail 52 is made of insulating material. The pitch and rotation direction of the spiral guide rail 52 are set the same as those of the coil 4. A tidying module 53 is slidably connected to the spiral guide rail 52. One end of the tidying module 53 is tightly against the coil 4. Since the pitch and rotation direction of the spiral guide rail 52 are set the same as those of the coil 4, when the tidying module 53 moves along the spiral guide rail 52, it can sort out the loose coil 4, rewind it, and press it, thereby ensuring that the coil 4 returns to its original winding state and maintains the stability of its inductance.

[0023] The sorting module 53 includes a slider body 531, on the bottom surface of which a gathering plate 532 is symmetrically fixedly connected, and a ball 533 is movably embedded in the middle of the inner wall of each gathering plate 532. Both ends of the inner walls of the two gathering plates 532 are rotatably connected to clamping rollers 534. When the sorting module 53 moves, the coil 4 that has been offset due to loosening returns to its original position under the drive of the gathering plate 532, and is centered under the action of the ball 533 on both sides. At this time, the clamping roller 534 presses the reset coil 4 to make it firmly wound, so that the loose coil 4 can be easily rewound without removing the inductor for inspection, thereby improving the efficiency during maintenance.

[0024] A battery 535 is embedded in the side wall of the slider body 531, a clamping groove 536 is opened on the top surface of the slider body 531, and a driving motor 537 is symmetrically embedded and fixedly connected on the inner wall of the clamping groove 536. A plurality of running wheels 538 are symmetrically rotatably connected on the top surface of the slider body 531, and a synchronous wheel 539 is fixedly connected at the top axis of the plurality of running wheels 538. The plurality of synchronous wheels 539 on the same side are connected through a synchronous belt 5310. The output shaft of each driving motor 537 is fixedly connected to the rotating shaft of one of the running wheels 538 on the same side, and each running wheel 538 is rollingly clamped on the spiral guide rail 52. Initially, the sorting module 53 is at one end of the first skeleton 1 or the second skeleton 2, and the outer wall of the coil 4 is between the two gathering plates 532 and tightly against the ball 533. When the coil 4 of the inductor becomes loose, the inductance of the coil 4 changes. At this time, the drive motor 537 is started to drive a walking wheel 538 fixed at one end of its output shaft to rotate, and drives multiple walking wheels 538 on the same side to rotate through the synchronous wheel 539 and the synchronous belt 5310, so as to drive the sorting module 53 to move along the spiral guide rail 52, from one end close to the first skeleton 1 to one end close to the second skeleton 2, or from one end close to the second skeleton 2 to one end close to the first skeleton 1.

[0025] Specifically, the coil 4 is wound with a certain number of turns and longitudinal length according to the use requirements, and then the spiral guide rail 52 with the same rotation direction and pitch as the coil 4 is wound, wherein the spiral guide rail 52 is made of insulating material. When the coil 4 wound on the inductor is accidentally loosened during use, since the number of winding turns and longitudinal length of the coil 4 are changed, its inductance changes accordingly. At this time, by starting the drive motor 537, a walking wheel 538 fixed at one end of its output shaft can be driven to rotate, and the synchronous wheel 539 and the synchronous belt 5310 can drive the same side of the inductor to rotate. The multiple walking wheels 538 rotate, so that the sorting module 53 moves once between the first frame 1 and the second frame 2 along the spiral guide rail 52. During this process, the loose coil 4 returns to the corresponding position of the spiral guide rail 52 under the gathering plate 532, and the balls 533 on both sides further engage the coil 4. As the sorting module 53 moves, the loose coil 4 is gradually sorted and reset, and the returned coil 4 is pressed by the clamping roller 534, thereby completing the rewinding of the coil 4. There is no need to remove the inductor for repair or replacement, which improves the efficiency of maintenance.

[0026] In order to reduce the electromagnetic interference of the inductor to the outside world, some inductors are often equipped with shielding covers. However, the shielding covers are usually fixed and cannot be switched according to the needs of use. Moreover, the shielding covers are easy to affect the heat dissipation of the inductor. Figure 1 and Figure 6 - Figure 8 As shown, the following preferred technical solutions are provided: The switching assembly 6 includes a shielding cover plate 61, and both ends of each shielding cover plate 61 are rotatably connected to a switching shaft 62. The multiple switching shafts 62 at both ends are rotatably connected to the side walls of the first skeleton 1 and the second skeleton 2 respectively, and the side walls of the multiple switching shafts 62 near one end of the second skeleton 2 are rotatably connected to a switching gear 63.

[0027] A gear ring 21 is rotatably connected to an outer wall of one side of the second frame 2 close to the iron core 3 , and a plurality of switching gears 63 are meshedly connected to the gear ring 21 . A threaded limiter 22 is passed through the side wall of the gear ring 21 .

[0028] Protective protrusions 64 are symmetrically arranged on the side wall of each shielding cover plate 61 , and a heat sink 65 is penetrated and fixedly connected to the side wall of each shielding cover plate 61 .

[0029] Specifically, when the inductor is less susceptible to external interference, the switching component 6 is operated to open the shielding cover of the inductor to improve the internal heat dissipation efficiency of the inductor. When it is necessary to reduce the electromagnetic interference of the inductor to the outside world, the shielding cover of the inductor is partially closed by operating the switching component 6, so that it can be flexibly adjusted according to different usage scenarios, and has a wide applicability. At the same time, when switching between without a shielding cover and with a shielding cover, there is no need to remove the original inductor, and the operation is relatively convenient. When switching, the multiple switching gears 63 are driven to rotate by rotating the ring gear 21, which can drive the multiple shielding cover plates 61 to rotate and close to form a complete shielding cover, and export the internal heat through the heat sink 65, or drive the multiple shielding cover plates 61 to rotate and open to enhance internal heat dissipation.

[0030] In order to solve the technical problem that when the inductor is damaged, its resistance value increases, resulting in excessive current and abnormal heating, and even causing circuit fire, which poses a safety hazard, such as Fig. 9 - Fig.11 As shown, the following preferred technical solutions are provided: The protective component 7 includes two connecting blocks 71 fixedly connected to the side walls of the first frame 1 and the second frame 2 respectively. A sliding groove 711 is opened on the top surface of each connecting block 71. A telescopic pin 712 is fixedly connected to the inside of the sliding groove 711. The fixed end of the telescopic pin 712 extends to the bottom surface of the connecting block 71, and the movable end of the telescopic pin 712 is fixedly connected to the electrode sheet 713.

[0031] The protection component 7 also includes two protection shells 72 fixedly connected to the side walls of the first frame 1 and the second frame 2 respectively. A sliding hole 721 is opened on the side wall of each protection shell 72. A first electromagnet 75 is fixedly connected in each sliding hole 721. An insulating rod 73 is fixedly connected to the side wall of the movable end of the telescopic pin 712. One end of the insulating rod 73 is fixedly connected to the limiting slider 74. A second electromagnet 76 is fixedly connected to the side wall of the insulating rod 73. The second electromagnet 76 is elastically connected to the first electromagnet 75 through a spring 77.

[0032] A bolt 722 is threadedly connected through the top surface of each protective shell 72 , one end of the bolt 722 is fixedly connected to a locking plate 723 , and the lead-out end of the coil 4 is arranged between the locking plate 723 and the electrode plate 713 .

[0033] Specifically, when the inductor is damaged, it affects the normal operation of the circuit. At the same time, its resistance value increases, resulting in excessive current, which in turn causes abnormal heating of the circuit. At this time, the first electromagnet 75 and the second electromagnet 76 are energized and attracted through a separate circuit, and the second electromagnet 76 moves downward through the insulating rod 73 to drive the movable end of the telescopic pin 712 to move downward, thereby causing the electrode sheet 713 to break contact with the lead-out end of the coil 4, thereby avoiding damage to the inductor, resulting in excessive current and abnormal heating, and even causing the circuit to catch fire.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
