Description

Technical Field

[0001] The present invention belongs to the technical field of inductors, and in particular relates to an intelligent inductor. Background Art

[0002] An inductor is an electronic component that can convert electrical energy into magnetic energy and store it. It is usually composed of a coil of wire. Sometimes a magnetic material is inserted into the coil as a core to enhance the inductor's performance. Its operating principle is based on the law of electromagnetic induction: when current passes through an inductor, a magnetic field is generated around it. The strength of the magnetic field is proportional to the magnitude of the current. When the current changes, the magnetic field also changes accordingly, thereby inducing an electromotive force in the inductor, hindering the change in current.

[0003] Chinese invention patent CN115910550A relates to the field of inductor technology, and relates to a new type of inductor, which includes a first core, a second core, a conductive coil structure and an inductance control structure. The second core is connected to the first core, and there is a gap between the first core and the second core. The conductive coil structure is located between the first core and the second core, and the inductance control structure fills the gap between the first core and the second core. The inductor has low inductance efficiency and poor inductance effect.

[0004] Chinese invention patent CN117976357B relates to a high-frequency, high-power resonant inductor, comprising a flexible frame with terminals at both ends. The terminal has a positioning groove at the bottom and a through hole on the side of the terminal. The accommodating cavity contains a soft magnetic sheet with a coil wound around it. The resonant inductor also includes a connecting seat fixedly connected to the terminal. The inductor is difficult to install and has low inductance accuracy.

[0005] When actually soldering the inductor to the circuit board, the height and position of the solder pad above the circuit board are uncertain. Therefore, the soldering position and soldering height of the inductor are easily offset when soldering the inductor to the circuit board. This not only reduces the soldering quality but also affects the subsequent normal operation of the inductor.

[0006] At the same time, during the welding process between the inductor and the circuit board, the volatilization of flux will produce impurities. If the impurities enter the interior of the inductor and adhere to the outer surface of the coil, it will cause contamination of the outer surface of the coil, thereby reducing the cleanliness and inductance effect of the inductor.

[0007] When the inductor is working continuously, the current flowing through the coil inside the inductor changes, which will cause the internal temperature of the inductor to change accordingly. However, the existing technologies lack the function of adaptively adjusting the internal temperature of the inductor, which in turn affects the continuous stability of the inductor.

[0008] Furthermore, when the heat dissipation efficiency of the inductor is adjusted, the shielding effect of the inductor against external electromagnetic interference changes accordingly, thereby making it impossible to ensure that the inductor continues to operate stably in a stable magnetic field environment.

[0009] When a short circuit occurs inside the circuit board or coil and the current flowing is too large, the temperature inside and outside the inductor increases to the maximum value. If the inductor remains in a high temperature state for a long time at this time, it will not only cause damage to the inductor itself, but may also cause major safety problems such as fire on the circuit board.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0046] like Figures 1 to 10 As shown, an intelligent inductor includes a shell component 1, an inductor component 2 is provided inside the shell component 1, and the shell component 1 shields and protects the internal inductor component 2 to prevent the inductor component 2 from being subjected to external electromagnetic interference during working inductance. Two control components 3 are symmetrically provided on both sides of the shell component 1. The control components 3 adjust the heat dissipation efficiency according to changes in the inductor component 2 and the external temperature, thereby ensuring that the working temperature of the inductor component 2 remains constant at all times. A plurality of support components 4 are evenly provided on the bottom of the shell component 1. The support components 4 provide stable support for the shell component 1. When a short circuit occurs in the inductor component 2 or the circuit board, causing excessive current and excessive temperature, the support components 4 drive the inductor component 2 to move and ultimately achieve rapid power-off protection.

[0047] The shell assembly 1 includes a shielding shell 101, which is mostly made of metal or magnetic material. Therefore, the shielding shell 101 can shield external electromagnetic interference, thereby ensuring that the internal inductor component 2 continues to work stably. An inductor cavity 102 is opened inside the shielding shell 101, and the inductor cavity 102 prepares a suitable space for the operation of the internal inductor component 2. A plurality of heat dissipation holes 107 are symmetrically opened on both sides of the shielding shell 101. One end of the heat dissipation hole 107 is connected to the inside of the inductor cavity 102. The heat dissipation hole 107 continuously exchanges heat between the inductor cavity 102 and the external environment, thereby ensuring that the inductor component 2 inside the inductor cavity 102 is in a suitable and appropriate working temperature environment, further improving the inductance quality and inductance efficiency of the inductor.

[0048] An insertion hole 103 is provided at the bottom of the shielding shell 101. The inner wall of the insertion hole 103 matches the outer surface of the coil 201.

The insertion hole 103 facilitates the subsequent insertion of the inductor component 2 into the inductor cavity 102 for operation. A positioning groove 105 is connected to one side of the insertion hole 103. The setting of the positioning groove 105 facilitates the positioning and correction process during the installation of the inductor component 2. The inner wall of the insertion hole 103 is provided with an end cover 104. The end cover 104 clamps and fixes the end of the insertion hole 103, thereby improving the inductor working stability of the inductor component 2 inside the inductor cavity 102.

[0049] The inductor assembly 2 includes a coil 201, which is the core part of the inductor and is usually made of a wound wire. The more turns the winding has, the greater the inductance is usually. Current is passed into the coil 201 and inductance is generated, thereby enabling the conversion of electrical energy into magnetic energy and storing it. A skeleton 205 is provided inside the coil 201 to support and protect the coil 201, ensuring the winding tension and stability of the coil 201, and the heat dissipation hole 107 is matched with the coil 201. The heat dissipation hole 107 discharges the heat generated by the coil 201 during operation, thereby ensuring that the coil 201 continues to work stably.

[0050] An iron core 204 is provided inside the skeleton 205. The iron core 204 is ferromagnetic and can enhance the magnetic flux density of the inductor, thereby increasing the inductance. A mounting groove 108 is provided at one end of the inductor cavity 102 away from the end cover 104. The outer surface of one end of the skeleton 205 is engaged with the inner wall of the mounting groove 108. The mounting groove 108 is used to support and fix the skeleton 205 and the internal iron core 204, thereby improving the positioning and support effect of the skeleton 205 and the coil 201. The other end of the skeleton 205 is engaged with the inner wall of the end cover 104. The material of the skeleton 205 is plastic. The end cover 104 engages and fixes the other end of the skeleton 205, thereby ensuring the sealing effect of the inductor cavity 102 and achieving the support and positioning performance of the skeleton 205 and the coil 201.

[0051] A fixing ring 209 is provided on the outer surface of one side of the skeleton 205. The diameter of the fixing ring 209 is larger than the diameter of the mounting groove 108. One end of the fixing ring 209 is fixedly engaged with the inner wall of the inductor cavity 102. At the same time, the other end of the fixing ring 209 fixes the side wall of the coil 201, further improving the supporting and fixing effect of the coil 201. A vertical plate 206 is provided on the outer surface of the other side of the skeleton 205. The vertical plate 206 matches the positioning groove 105. The vertical plate 206 cooperates with the positioning groove 105 to improve the positioning accuracy of the installation. The vertical plate 206 An elastic sheet 207 is provided on one side close to the coil 201. The elastic sheet 207 itself is elastic. A clamping half ring 208 is provided on the other side of the elastic sheet 207. The opposite end faces of the clamping half ring 208 and the fixing ring 209 are clamped and fixed to the two side walls of the coil 201. Under the elastic force of the elastic sheet 207, the clamping half ring 208 is elastically clamped to one end of the coil 201, and cooperates with the fixing ring 209 to further improve the positioning and clamping effect of the coil 201 inside the inductor cavity 102, thereby ensuring the subsequent inductance stability of the coil 201.

[0052] Two conductive slots 106 are provided inside the shielding shell 101, and the two conductive slots 106 have different heights. One end of the coil 201 is electrically connected to the first pin 202, and the other end of the coil 201 is electrically connected to the second pin 203. The current inside the coil 201 enters along the first pin 202 and flows out along the second pin 203 after circulating around the coil 201, thereby realizing the inductive operation of the coil 201. The first pin 202 and the second pin 203 have different heights. The outer surfaces of the first pin 202 and the second pin 203 are both clipped and fixed to the inner wall of the conductive slot 106, and the first pin 202 and the second pin 203 extend along the conductive slot 106, thereby not only improving the subsequent power-on stability of the first pin 202 and the second pin 203, but also the conductive slot 106 can clip and fix the positions of the first pin 202 and the second pin 203, thereby preventing the first pin 202 and the second pin 203 from being detached from the solder pads in the circuit board when the inductor shakes.

[0053] The regulating component 3 includes an outer shielding slide 301 and an inner shielding slide 302. The outer shielding slide 301 is sealed and slidably connected to the outer wall of the shielding shell 101 on the side close to the coil 201, and the inner shielding slide 302 is sealed and slidably connected to the inner wall of the inductor cavity 102 on the side away from the coil 201. The inner shielding slide 302 cooperates with the outer shielding slide 301 to adjust the heat dissipation efficiency and shielding effect. The inner shielding slide 302 is in contact with the outer surface of the coil 201 on the side close to the coil 201, so that the inner shielding slide 302 can also scrape and clean the outer surface of the coil 201 to ensure that the inside of the inductor cavity 102 is normal and stable. Two arc-shaped holes 311 are symmetrically provided on the top of the shielding shell 101, and the bottom of the arc-shaped hole 311 is connected to the inside of the inductor cavity 102. The outer surface of the inner shielding slide 302 is sealed and slidably connected to the inner wall of the arc-shaped hole 311, so that the inner shielding slide 302 moves inside the arc-shaped hole 311 and ensures the shielding effect of the shielding shell 101 on the coil 201.

[0054] The shielding shell 101 is evenly provided with a plurality of side grooves 306. The openings of the side grooves 306 face the interior of the inductor cavity 102 and the exterior of the shielding shell 101, respectively. An expansion bellows 307 is provided at the inner top of the side groove 306. A thermal expansion material is provided inside the expansion bellows 307. The thermal expansion material expands with heat and contracts with cold. A sealing slider 309 is provided at the bottom of the expansion bellows 307. The sealing slider 309 is in sealing sliding connection with the inner wall of the side groove 306. Therefore, when the temperature around the expansion bellows 307 changes, the sealing slider 309 is correspondingly driven to move up and down along the side groove 306. The side walls of the sealing slider 309 are respectively fixedly connected to the side walls of the outer shielding slide 301 or the inner shielding slide 302. The sealing slider 309 drives the outer shielding slide 301 or the inner shielding slide 302 in the corresponding position to move up and down, thereby adjusting the heat dissipation efficiency and shielding effect, thereby ensuring the continuous and stable operation of the coil 201 inside the inductor cavity 102.

[0055] A return spring 308 is provided at the inner top of the side groove 306, and the bottom of the return spring 308 is fixedly connected to the top of the sealing slider 309. The return spring 308 is located inside the expansion bellows 307. The setting of the return spring 308 further improves the elastic return performance of the sealing slider 309. An elastic moving block 310 is provided at the bottom of the sealing slider 309. The bottom of the side groove 306 is connected to the top of the bottom groove 401. The outer surface of the elastic moving block 310 is sealed and slidably connected to the inner wall of the side groove 306 and the inner wall of the bottom groove 401 respectively. When the sealing slider 309 moves up and down, it synchronously drives the elastic moving block 310 to move up and down inside the bottom groove 401.

[0056] A plurality of first docking holes 303 are uniformly formed inside the outer shielding plate 301, and a plurality of second docking holes 304 are uniformly formed inside the inner shielding plate 302. The first docking holes 303 and the second docking holes 304 match each other and achieve a highly efficient heat dissipation process for the coil 201 inside the inductor cavity 102. An air guide hose 305 is provided between the first docking holes 303 and the second docking holes 304. The air guide hose 305 is used to discharge heat from the coil 201 during operation, thereby adaptively adjusting the heat dissipation efficiency and heat dissipation effect of the coil 201 according to the temperature difference between the outside world and the inside of the inductor cavity 102.

[0057] The air guide hose 305 is located inside the heat dissipation hole 107, and the inner wall of the air guide hose 305 is smooth, so the heat generated by the coil 201 when working can flow outward along the air guide hose 305. The first docking hole 303 and the second docking hole 304 both correspond to the heat dissipation hole 107 and are staggered. The end of the second docking hole 304 away from the first docking hole 303 corresponds to the outer surface of the coil 201. When the temperature inside the inductor cavity 102 rises, the thermal expansion material inside the expansion bellows 307 expands due to the heat and drives the sealing slider 309 to move downward along the side groove 306. The sealing slider 309 simultaneously drives the inner shielding slide 302 to move downward, and the second docking hole 304 is aligned with the heat dissipation hole 107. As the misalignment area increases and the diameter difference of the air guide hose 305 increases, the efficiency of discharging the heat inside the inductor cavity 102 toward the outside along the air guide hose 305 under the action of the airflow increases, thereby improving the heat dissipation efficiency of the coil 201 inside the inductor cavity 102. Both side walls of the outer shielding slide 301 and the inner shielding slide 302 are provided with an insulating layer, which moves continuously as the outer shielding slide 301 and the inner shielding slide 302 move up and down. The provision of the insulating layer not only adjusts the insulation and magnetic resistance effect inside the inductor cavity 102, but also achieves a scraping and cleaning effect on the outer surface of the shielding shell 101, the inner wall of the inductor cavity 102, and the outer surface of the coil 201, thereby ensuring that the coil 201 continuously and stably performs the inductance process.

[0058] The support assembly 4 includes a plurality of bottom grooves 401, and the bottom grooves 401 are slidably connected with support legs 403. The support legs 403 continuously move up and down inside the bottom grooves 401, which not only supports the shielding shell 101, but also drives the shielding shell 101 to move upward when the current flowing into the coil 201 is too large and causes the temperature inside the inductor cavity 102 to be too high. The shielding shell 101 drives the first pin 202 and the second pin 203 to move upward and disengage from the pad of the circuit board, thereby realizing the circuit breaker protection process of the inductor.

[0059] The support leg 403 is fixed to the upper and lower surfaces of the support leg 403, and the support leg 403 is fixed to the upper and lower surfaces of the support leg 403. The support leg 403 is fixed to the upper and lower surfaces of the support leg 403, and the support leg 403 is fixed to the upper and lower surfaces of the support leg 403. The support leg 403 is fixed to the upper and lower surfaces of the support leg 403, and the support leg 403 is fixed to the upper and lower surfaces of the support leg 403.

[0060] When the inductor is actually soldered to the circuit board, the height and position of the soldering pad above the circuit board are uncertain. Therefore, when the inductor is soldered to the circuit board, the soldering position of the inductor is easily offset, which not only reduces the soldering quality, but also affects the normal working quality of the subsequent inductor. At the same time, during the soldering process of the inductor and the circuit board, the flux is easy to volatilize and produce impurities, etc. The impurities will enter the inductor and adhere to the outer surface of the coil 201, thereby causing contamination of the outer surface of the coil 201, which correspondingly reduces the inductance quality of the subsequent inductor. When the inductor continues to work, the current flowing into the coil 201 inside the inductor changes and causes the inductor cavity 10 to be deformed. 2. The internal and external temperatures change accordingly, but the existing technologies lack the function of adaptively adjusting the internal temperature of the inductor cavity 102, which correspondingly reduces the continuous and stable inductor operation of the inductor. When the heat dissipation efficiency of the inductor is adjusted, the shielding effect of the inductor against external electromagnetic interference also changes, and thus the continuous and stable operation of the inductor cannot be guaranteed. When the current inside the circuit board or the coil 201 or the circuit board is too large, the internal and external temperatures of the inductor cavity 102 increase to the maximum value. At this time, if the inductor is still in a high-temperature working state for a long time, it will not only cause damage to the inductor structure itself, but may also cause serious safety problems such as fire of the circuit board.

[0061] In order to solve the above problems, when the smart inductor is actually used, the coil 201 is first wound around the outer surface of the skeleton 205, and the clamping half ring 208 and the fixing ring 209 are clamped and fixed to the coil 201 under the elastic force of the elastic sheet 207. At the same time, the iron core 204 is inserted into the inside of the skeleton 205, and the coil 201 is inserted along the insertion hole 103 under the positioning action of the positioning groove 105 and the vertical plate 206. The end of the skeleton 205 is fixedly engaged with the installation groove 108. After the assembly of the coil 201 is completed, the end cover 104 is tightened to complete the assembly process of the inductor.

[0062] Then, the inductor is moved above the circuit board and the bottom of the support leg 403 is pressed and contacted with the top of the circuit board, and the first pin 202 and the second pin 203 are matched with the pads above the circuit board. At the same time, the operator presses down the shielding shell 101, and the shielding shell 101 drives the support plate 404 to move downward. The support plate 404 stretches the connecting spring 406 to move downward, and the support leg 403 drives the matching plate 402 to move upward to a suitable height relative to the shielding shell 101 inside the bottom groove 401. At this time, the shielding shell 101 drives the first pin 202 and the second pin 203 to move downward and press and contact with the top of the pad above the circuit board, thereby achieving the positioning and fixing effect of the inductor during welding. At the same time, with the help of the elastic connection between the support leg 403 and the connecting spring 406, the inductor adapts to the different heights of the pads above the circuit board, thereby improving the accuracy and stability of subsequent welding and ensuring the continuous and stable operation of the inductor.

[0063] Afterwards, the operator uses a welding gun to respectively weld the first pin 202 and the second pin 203 to the pads on the circuit board. At the same time, during the welding process, the temperature around the shielding shell 101 rises, and the thermal expansion material inside the expansion bellows 307 expands due to the heat. The expansion bellows 307 drives the sealing slider 309 to stretch the reset spring 308 and move downward along the side groove 306. The sealing slider 309 correspondingly drives the outer shielding slide 301 and the inner shielding slide 302 to move downward, and the outer shielding slide 301 drives the multiple first docking holes 303 along the screen. The outer wall of the shielding shell 101 moves downward, and the inner shielding slide 302 drives the multiple second docking holes 304 to move downward along the arc-shaped hole 311. The first docking holes 303 and the second docking holes 304 are both misaligned and blocked with the heat dissipation holes 107. The first docking holes 303 and the second docking holes 304 drive the air guide hose 305 to undergo elastic deformation and be in a closed state. Therefore, impurities generated during the welding process will not enter the interior of the inductor cavity 102 along the air guide hose 305 and cause contamination on the outer surface of the coil 201, further improving the sustainability and stability of the subsequent inductance.

[0064] At the same time, when the sealing slider 309 moves downward, the elastic moving block 310 is synchronously driven to move downward, and the bottom of the elastic moving block 310 is squeezed and contacted with the top of the matching plate 402. However, since the operator presses the shielding shell 101 to a suitable height at this time, the elastic moving block 310 undergoes elastic deformation and correspondingly improves the support and positioning effect on the top of the matching plate 402. At the same time, the connecting spring 406 exerts a pulling force on the matching plate 402, further improving the stability and positioning of the matching plate 402 and the support leg 403 during the welding process, thereby avoiding the welding position deviation caused by unstable operation of the welder during the welding process and reducing the subsequent power-on stability of the coil 201.

[0065] After welding is completed, the temperature around the shielding shell 101 drops, and the volume of the thermal expansion material inside the expansion bellows 307 continues to decrease to the initial value under the principle of its own thermal expansion and contraction. Then, under the elastic force of the expansion bellows 307 and the return spring 308, the sealing slider 309 is driven to move upward along the side groove 306 to return to its original position. The sealing slider 309 drives the outer shielding slides 301 and the inner shielding slides 302 on both sides to move upward to return to their original positions. The outer shielding slides 301 and the inner shielding slides 302 drive the multiple first docking holes 303 and the second docking holes 304 to move upward to return to their original positions. The first docking holes 303 and the second docking holes 304 Located above the heat dissipation hole 107 and connected to the offset part of the heat dissipation hole 107, the air guide hose 305 is connected to the internal part of the heat dissipation hole 107. At the same time, multiple legs 403 are supported and fixed to the top of the circuit board, and under the elastic force of the connecting spring 406, the legs 403 are elastically connected to the shielding shell 101. Therefore, when the circuit board shakes, the elastic connection of the legs 403 with the return spring 308 further improves the elastic support performance of the coil 201 inside the shielding shell 101, effectively avoiding the coil 201 from colliding with the inner wall of the inductor cavity 102 and causing damage, thereby improving the continuity and stability of the operation of the coil 201.

[0066] After that, the circuit board works normally. The current flowing inside the circuit board enters the first pin 202 along the pad. The current inside the first pin 202 passes through the coil 201 and flows out to the second pin 203. The current inside the second pin 203 passes through another pad and flows into the inside of the circuit board, thereby realizing the path of the coil 201, ensuring the continuous and stable inductance operation of the inductor. When the current passes through the coil 201, the corresponding temperature rises. The temperature inside the inductor cavity 102 rises accordingly and is higher than the external temperature. The thermal expansion material inside the expansion bellows 307 near the end of the coil 201 increases in volume due to the principle of thermal expansion and contraction, and the expansion bellows 307 drives the sealing The slider 309 stretches the return spring 308 to move downward along the side groove 306. The sealing slider 309 drives the inner shielding slider 302 to move downward along the arc hole 311. The inner shielding slider 302 drives the multiple second docking holes 304 to move downward and pass over the heat dissipation hole 107 and then locate below the heat dissipation hole 107. The second docking holes 304 correspondingly drive the air guide hose 305 to move downward near the end of the coil 201. The internal diameter of the air guide hose 305 changes. Under the action of air pressure, the heat inside the inductor cavity 102 is continuously discharged to the outside along the air guide hose 305. The internal temperature of the inductor cavity 102 remains constant and the working temperature suitability of the coil 201 is improved.

[0067] When the amount of current flowing into the coil 201 increases, the heat generated by the coil 201 increases and the temperature inside the inductor cavity 102 increases accordingly. The thermal expansion material inside the expansion bellows 307 near the end of the coil 201 increases in volume due to the principle of thermal expansion and contraction. The expansion bellows 307 drives the sealing slider 309 to stretch the reset spring 308 and move downward along the side groove 306. The sealing slider 309 drives the inner shielding slide 302 to move downward along the arc hole 311. The inner shielding slide 302 drives the multiple second docking holes 304 to move downward. The overlapping area of ​​the second docking holes 304 and the heat dissipation holes 107 decreases, and the second docking holes 304 are closed. 4 correspondingly drives the air guide hose 305 to move downward near the end of the coil 201, the opening of the air guide hose 305 near the end of the coil 201 decreases, and the internal diameter difference of the air guide hose 305 changes accordingly. Specifically, the diameter difference of the air guide hose 305 gradually increases from one end of the coil 201 to the other end. Under the influence of the principles of air pressure and air flow, the high-temperature gas inside the inductor cavity 102 can be continuously discharged to the outside through the air guide hose 305 more quickly, thereby correspondingly improving the heat discharge efficiency inside the inductor cavity 102, ensuring that the internal temperature of the inductor cavity 102 is always at a stable value, and improving the inductance accuracy and stability of the coil 201.

[0068] Furthermore, when the current flowing through the coil 201 remains unchanged, the heat generated by the coil 201 itself remains unchanged. However, when the external temperature rises, the heat generated mainly by the operation of other components of the circuit board increases. This heat will reduce the efficiency of the heat inside the inductor cavity 102 being discharged to the outside along the air guide hose 305, thereby causing the temperature of the inductor cavity 102 to continue to rise and affecting the normal inductor operation of the coil 201.

[0069] At this time, the thermal expansion material inside the expansion bellows 307 located at the end away from the coil 201 increases in volume under the principle of thermal expansion and contraction, and the expansion bellows 307 drives the sealing slider 309 to stretch the reset spring 308 and move downward along the side groove 306, and the sealing slider 309 drives the outer shielding slide 301 to move downward along the outer side of the shielding shell 101, and the outer shielding slide 301 drives multiple first docking holes 303 to move downward, and the overlapping area of ​​the first docking holes 303 and the heat dissipation holes 107 increases. The first docking holes 303 correspondingly drive the air guide hose 305 to move downward away from the end of the coil 201, and the air guide hose 305 moves away from the end of the coil 201. The opening at the end of the inductor cavity 102 increases, while the opening of the air guide hose 305 at the end close to the coil 201 remains almost unchanged. Therefore, the internal diameter difference of the air guide hose 305 changes accordingly. Specifically, the diameter difference of the air guide hose 305 gradually increases from one end of the coil 201 to the other end. Under the action of the air pressure and air flow principles, the high-temperature gas inside the inductor cavity 102 can be continuously discharged to the outside along the air guide hose 305 at a faster speed, thereby ensuring that when the external temperature changes, the heat discharge rate inside the inductor cavity 102 is correspondingly adjusted, thereby ensuring the stability and constant temperature of the working environment of the coil 201 inside the inductor cavity 102, and improving the inductance quality of the inductor.

[0070] When the external temperature or the temperature inside the inductor cavity 102 rises, the magnetic permeability of the iron core 204 will decrease accordingly, which will cause the inductance value of the coil 201 to decrease and correspondingly reduce its own shielding ability against electromagnetic interference. At this time, according to the above process, the thermal expansion material inside the expansion bellows 307 expands due to heat and drives the outer shielding slide 301 or the inner shielding slide 302 to move downward through the sealing slider 309, which not only adjusts the diameter difference of the air guide hose 305 and improves the heat dissipation effect, but also increases the shielding blocking area of ​​the outer shielding slide 301 or the inner shielding slide 302 for the internal coil 201, further improving the effect of shielding the internal coil 201 from external electromagnetic interference when the temperature rises, thereby ensuring the continuous and stable inductance operation of the coil 201 inside the inductor cavity 102.

[0071] At the same time, when the outer shielding slide 301 or the inner shielding slide 302 moves up and down, the outer shielding slide 301 applies a scraping and cleaning effect to the outer surface of the shielding shell 101, and the inner shielding slide 302 applies a scraping and cleaning effect to the inner wall of the inductor cavity 102 and the outer surface of the coil 201, thereby preventing external dust and impurities from adhering to the outer surface of the shielding shell 101 or the inner wall of the inductor cavity 102 and the outer surface of the coil 201, further improving the cleanliness and dust-freeness of the inductor, and ensuring that the dust and impurities will not affect the normal inductance operation of the coil 201 inside the inductor cavity 102.

[0072] When the current flowing through the coil 201 continuously increases to a maximum value, the temperature inside the inductor cavity 102 continuously increases and reaches a maximum value. During this process, the volume of the thermal expansion material inside the expansion bellows 307 increases to a maximum value under the principle of thermal expansion and contraction. The expansion bellows 307 drives the sealing slider 309 to stretch the reset spring 308 and move downward along the side groove 306 to a maximum distance. The sealing slider 309 drives both the outer shielding slider 301 and the inner shielding slider 302 to move downward to a maximum value. Both the outer shielding slider 301 and the inner shielding slider 302 drive the first docking hole 303 and the second docking hole 304 to move downward to a maximum value and become misaligned and blocked with the heat dissipation hole 107, thereby preventing the high temperature inside the inductor cavity 102 from being discharged along the air guide hose 305 and causing damage to other components above the circuit board.

[0073] At the same time, when the sealing slider 309 slides downward, it simultaneously drives the elastic moving block 310 to slide downward along the bottom groove 401 to the maximum distance. The bottom of the elastic moving block 310 is squeezed and contacted with the top of the matching plate 402, and drives the matching plate 402 to move downward along the bottom groove 401. At this time, the elastic force of the connecting spring 406 drives the support leg 403 to move downward along the limiting hole 405 inside the support plate 404. The support leg 403 exerts an upward reaction force on the shielding shell 101. Under this force, the shielding shell 101 drives the first pin 202 and the second pin 203 to disconnect the circuit from the pad above the circuit board. No current is passed into the coil 201, and the temperature inside the inductor cavity 102 no longer rises. In this way, the inductor is disconnected from the pad above the circuit board in the event of a short circuit and the power is cut off, thereby preventing the inductor from being in a short-circuit state for a long time and causing major safety accidents such as fire, thereby further improving the safety of the inductor.

[0074] If only the inductor itself is short-circuited and generates high temperature, the internal temperature will continue to drop as the inductor and the solder pad above the circuit board are short-circuited. Under the elastic force of the reset spring 308 and the expansion bellows 307 itself, the sealing slider 309 is driven to move upward and return to its original position. The sealing slider 309 drives the outer shielding slide 301 and the inner shielding slide 302 to move upward and return to their original positions. The sealing slider 309 drives the elastic moving block 310 to move upward along the bottom groove 401 and return to its original position. The bottom of the elastic moving block 310 is separated from the extrusion contact with the top of the matching plate 402. Under the elastic force of the connecting spring 406, the matching plate 402 is driven to move upward and return to its original position. The matching plate 402 drives the support leg 403 to move upward and return to its original position. The inductor can be re-welded and assembled for use.

[0075] If other components of the circuit board are short-circuited and generate high temperature, the temperature around the inductor reaches the maximum value at this time, and the volume of the thermal expansion material inside the expansion bellows 307 is heated to the maximum value. The expansion bellows 307 drives the outer shielding slide 301 and the inner shielding slide 302 to move downward to the maximum distance through the sealing slider 309. The first docking hole 303 and the second docking hole 304 are both misaligned and blocked with the heat dissipation hole 107. The air guide hose 305 is in a blocked and closed state. The high-temperature impurities generated when the circuit board catches fire will not enter the inductor cavity 102 along the air guide hose 305 and damage the normal operation of the coil 201, further improving the safety protection effect of the inductor. After the operator completes the trimming of the top of the circuit board, the inductor is re-installed. It can be fixed by welding, and as described above, when the sealing slider 309 slides downward, it simultaneously drives the elastic moving block 310 to slide downward along the bottom groove 401 to the maximum distance, and the bottom of the elastic moving block 310 drives the support leg 403 to move downward along the limiting hole 405 inside the support plate 404 through the matching plate 402, and the support leg 403 applies an upward reaction force to the shielding shell 101. Under this force, the shielding shell 101 drives the first pin 202 and the second pin 203 to disconnect the circuit from the soldering pad above the circuit board, and no current is passed into the coil 201, thereby effectively avoiding the coil 201 from still working and causing damage to its own structure when a short circuit occurs on the circuit board, thereby effectively realizing the rapid circuit protection of the inductor.
