Description

Technical Field

[0001] This invention belongs to the field of inductor technology, and specifically discloses an inductor with coil protection function. Background Technology

[0002] An inductor is a passive electronic component that stores magnetic field energy. Its core consists of a coil winding, often used in conjunction with a magnetic core. The coil is made of insulated wire; when current flows through it, it generates a magnetic field that stores energy, exhibiting the characteristic of passing direct current and blocking alternating current. The magnetic core (such as ferrite or silicon steel sheets) utilizes high permeability to enhance the magnetic field, increasing inductance and reducing size. Based on structure, inductors can be divided into cored inductors and air-core inductors. Cored inductors are used for power supply filtering and energy storage, while air-core inductors are suitable for high-frequency circuits. Their performance parameters include inductance, rated current, and Q value, and they are widely used in filtering, resonant, and electromagnetic compatibility circuits.

[0003] In the prior art, the inductor housing is usually integrated with the magnetic core and coil winding. Apart from the protection of the housing, the magnetic core and coil winding of the inductor have no other protective structure. This means that when the inductor is subjected to impact, the housing will be damaged, which in turn will easily lead to damage to the magnetic core and coil winding, thus reducing the service life of the inductor. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide an inductor with coil protection function to solve the problem in the prior art where the inductor housing is usually integrated with the magnetic core and coil winding, which leads to the housing being damaged after the inductor is subjected to impact, which in turn easily leads to the damage of the magnetic core and coil winding, thus reducing the service life of the inductor.

[0005] To achieve the above objectives, the present invention provides an inductor with coil protection function, comprising a protective housing, a magnetic core, and a coil winding, wherein the coil winding is wound around the outside of the magnetic core, and both the magnetic core and the coil winding are disposed inside the protective housing; Two assembly mechanisms are respectively disposed on both sides of the protective shell, and the two ends of the magnetic core are respectively disposed in the middle of the two assembly mechanisms; Two overload protection mechanisms are provided, with their top interiors respectively located outside both ends of the coil winding, and the overload protection mechanisms are connected to the bottom of the assembly mechanism.

[0006] In the above technical solution, preferably, the two assembly mechanisms include assembly jackets disposed at both ends of the protective shell. An installation slot is provided inside the middle of the assembly jacket on the side closest to the protective shell. An installation spring is fixedly connected to the side of the assembly jacket away from the protective shell. An installation plate is fixedly connected to the end of the installation spring away from the assembly jacket. Elastic inserts are fixedly connected to both ends of the installation plate on the side closest to the protective shell. A beveled insert is fixedly connected to the outside of one end of the elastic insert. Two fixing rings are fixedly connected to the outside of the protective shell. Two insertion slots are provided inside the fixing rings. The elastic inserts penetrate the inside of the insertion slots, and the beveled insert engages with the outside of the fixing ring.

[0007] In the above technical solution, preferably, the bottom of the assembled outer sleeve is fixedly connected to a sealing semicircular sleeve one, and the side of the sealing semicircular sleeve one away from the installation spring is fixedly connected to two sealing strips of different lengths. The bottom of the fixed mounting ring is fixedly connected to a sealing semicircular sleeve two, and the side of the sealing semicircular sleeve two near the sealing semicircular sleeve one has two sealing splicing grooves of different lengths.

[0008] In the above technical solution, preferably, a sealing ring is provided inside the fixing ring, and the assembly sleeve is inserted into the inside of the fixing ring.

[0009] In the above technical solution, preferably, the two ends of the magnetic core are respectively inserted into the two mounting slots, and the two ends of the magnetic core are respectively slidably connected to the two ends of the protective shell.

[0010] In the above technical solution, preferably, both the inner sides of the first sealing semicircular sleeve and the second sealing semicircular sleeve are provided with sealing gaskets, and the sealing strip is inserted into the inside of the sealing splicing groove.

[0011] In the above technical solution, preferably, the two overload protection mechanisms include an assembly cylinder disposed outside both ends of the coil winding. A metal conductor is fixedly connected to the bottom of the assembly cylinder, and two fixing ears are fixedly connected to the top of the assembly cylinder. A fuse is disposed inside the assembly cylinder. A connecting conductor is fixedly connected to the middle of the bottom end of the assembly cylinder and passes through the bottom of the assembly cylinder. A conductor spring is disposed inside the assembly cylinder. Conductor contact plates are fixedly connected to both ends of the conductor spring. Insertion plates are fixedly connected to the outside of both the first sealing semicircular sleeve and the second sealing semicircular sleeve.

[0012] In the above technical solution, preferably, both conductor contact plates are slidably connected inside the assembly cylinder, and the bottom of the fuse is in contact with the top of the connecting conductor.

[0013] In the above technical solution, preferably, the tops of the two upper conductor contact plates are in contact with the bottoms of both ends of the coil winding, and the bottom of the lower conductor contact plate is in contact with the top of the fuse.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can protect the magnetic core and coil winding inside the inductor through the assembly mechanism. When the mounting plate is impacted, the mounting spring can buffer the impact force and then disperse the impact force to prevent damage to the protective shell, thereby further protecting the magnetic core and coil winding inside the inductor and improving the service life of the inductor.

[0016] 2. The present invention avoids the integrated design of the outer shell and the magnetic core through the assembly mechanism, which allows the magnetic core and the coil winding to be removed from the protective shell separately and replaced individually. Therefore, if one of them is damaged, it is not necessary to replace the whole structure, but only the damaged structure needs to be replaced, which effectively reduces the maintenance cost. 3. This invention protects the inductor through an overload protection mechanism, preventing damage to the inductor due to overload, thus improving the service life of the inductor. It also facilitates fuse replacement, improving the efficiency of inductor replacement and maintenance. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-10 An inductor with coil protection function is shown, comprising a protective housing 1, a magnetic core 4, and a coil winding 5. The coil winding 5 is wound around the outside of the magnetic core 4, and the magnetic core 4 and the coil winding 5 wound on it can form an inductor. Both the magnetic core 4 and the coil winding 5 are disposed inside the protective housing 1. Two assembly mechanisms 2 are respectively disposed on both sides of the protective housing 1. The assembly mechanisms 2 are used to install the magnetic core 4 and the coil winding 5, and can buffer impact forces, thereby protecting the magnetic core 4 and the coil winding 5. The two ends of the magnetic core 4 are respectively disposed in the middle of the two assembly mechanisms 2. Two overload protection mechanisms 3 are respectively disposed at the top interior of the two ends of the coil winding 5, and the overload protection mechanisms 3 are connected to the bottom of the assembly mechanism 2.

[0022] The two assembly mechanisms 2 include assembly sleeves 201 disposed at both ends of the protective housing 1. An installation slot 202 is provided inside the middle of the assembly sleeve 201 on the side closest to the protective housing 1. After the assembly sleeve 201 is installed at both ends of the protective housing 1, the magnetic core 4 can be inserted into the installation slot 202, thereby installing the magnetic core 4 and further installing the coil winding 5. An installation spring 203 is fixedly connected to the side of the assembly sleeve 201 away from the protective housing 1. An installation plate 204 is fixedly connected to the end of the installation spring 203 away from the assembly sleeve 201, providing an installation position. Both ends of the installation plate 204 on the side closest to the protective housing 1 are fixedly connected to elastic inserts 205, which are elastic. A beveled insert block 206 is fixedly connected to the outside of one end of the elastic insert 205. Two fixing rings 209 are fixedly connected to the outside of the protective housing 1 for fixed installation. Two insertion slots 210 are provided inside the ring 209. The inclined insert 206 can pass through the inside of the insertion slot 210 and engage with the outside of the fixed mounting ring 209, thereby restricting the movement trajectory of the mounting plate 204. This can compress the mounting spring 203 and also allow the reaction force of the mounting spring 203 to act on the assembly sleeve 201, so that the assembly sleeve 201 is tightly inserted into the inside of the fixed mounting ring 209. The elastic insert 205 passes through the inside of the insertion slot 210. The inclined insert 206 engages with the outside of the fixed mounting ring 209. A sealing ring is provided inside the fixed mounting ring 209. The sealing ring can maintain the relative sealing of the inside of the protective shell 1. The assembly sleeve 201 is inserted into the inside of the fixed mounting ring 209. The two ends of the magnetic core 4 are respectively inserted into the inside of the two mounting slots 202. The two ends of the magnetic core 4 are respectively slidably connected to the inside of the two ends of the protective shell 1. The bottom of the assembled outer casing 201 is fixedly connected to a sealing semi-circular sleeve 207. Two sealing strips 208, one long and one short, are fixedly connected to the side of the sealing semi-circular sleeve 207 away from the mounting spring 203. The bottom of the fixed mounting ring 209 is fixedly connected to a sealing semi-circular sleeve 211. The splicing of the sealing semi-circular sleeve 207 and the sealing semi-circular sleeve 211 can wrap around the end of the coil winding 5, thus maintaining the relative neatness of the inside of the protective outer casing 1. Two sealing splicing grooves 212, one long and one short, are opened on the side of the sealing semi-circular sleeve 211 near the sealing semi-circular sleeve 207. The sealing strips 208 are inserted into the sealing splice... The interior of the groove 212 further maintains the sealing performance of the sealed semicircular sleeve 211 and the sealed semicircular sleeve 207 after splicing. Sealing gaskets are provided on the inner sides of both the sealed semicircular sleeve 207 and the sealed semicircular sleeve 211. These gaskets tightly wrap the outside of the coil winding 5, thereby increasing the sealing effect. The sealing strip 208 is inserted into the interior of the sealing splicing groove 212. When installing the magnetic core 4 and the coil winding 5 inside the protective housing 1, first fold up one end of the coil winding 5 and place the magnetic core 4 and the coil winding 5 inside the protective housing 1. Then, reset one end of the coil winding 5. The purpose of folding it up is not clearly stated. Folding up one end seems unrelated to the subsequent actions. Next, align the sealing semicircular sleeve 207 on the assembled outer casing 201 with the sealing semicircular sleeve 211 on the fixing mounting ring 209, and insert the sealing strip 208 into the sealing splicing groove 212. At this time, push the mounting plate 204 to compress the mounting spring 203, insert the elastic insert 205 into the insertion groove 210, and insert the inclined block 206 through the insertion groove 210. Since the side of the inclined block 206 away from the mounting plate 204 is inclined, and the elastic insert 205 is elastic, when the inclined block 206 contacts the inner wall of the insertion groove 210, it will exert a force on the inclined block 206 towards the protective outer casing 1 and bend the elastic insert 205. After the inclined block 206 passes through the inside of the insertion groove 210, the elastic insert 205 elastically returns to its original position, thereby allowing the inclined block 206 to move away from the protective outer casing 1. The mounting plate 204 is positioned such that the inclined insert 206 engages with the outside of the fixed mounting ring 209. At this time, the reaction force of the mounting spring 203 can exert a force on the mounting plate 204 away from the protective shell 1. However, under the action of the elastic insert 205 and the inclined insert 206, the mounting plate 204 will not move. Then, the reaction force of the mounting spring 203 can be applied to the assembly sleeve 201, so that the assembly sleeve 201 is tightly inserted into the inside of the fixed mounting ring 209. This allows the two ends of the magnetic core 4 to be stably set inside the two mounting slots 202. At the same time, when the two ends of the protective shell 1 are subjected to impact force, the mounting plate 204 can exert a force on the mounting spring 203 again and use the mounting spring 203 to dissipate the impact force, thereby reducing the impact force generated by the impact and protecting the magnetic core 4 and coil winding 5 inside the protective shell 1.

[0023] The two overload protection mechanisms 3 include assembly cylinders 301 located outside both ends of the coil winding 5. The assembly cylinders 301 provide installation positions. A metal conductor 302 is fixedly connected to the bottom of the assembly cylinder 301, providing electrical conductivity. Two fixing ears 303 are fixedly connected to the top of the assembly cylinder 301. A fuse 304 is installed inside the assembly cylinder 301, which can melt in case of overload, thus protecting the coil winding 5. A connecting conductor 305 is fixedly connected to the middle of the bottom end of the assembly cylinder 301, providing energization and penetrating the bottom of the assembly cylinder 301. A conductor spring 306 is installed inside the assembly cylinder 301, with both ends of the conductor spring 306 fixed. A conductor contact plate 307 is connected. When the end of the coil winding 5 is inserted into the top of the assembly cylinder 301, it can compress the conductor spring 306. The reaction force of the conductor spring 306 applies a force to the fuse 304 towards the connecting conductor 305, thereby ensuring that the fuse 304 is tightly installed inside the assembly cylinder 301 and preventing the fuse 304 from shaking inside the assembly cylinder 301, thus maintaining the stability of the energization. Insertion plates 308 are fixedly connected to the outside of both the sealing semicircular sleeve one 207 and the sealing semicircular sleeve two 211. After the insertion plates 308 are inserted into the fixing ears 303, the assembly cylinder 301 can be installed at the bottom of the sealing semicircular sleeve one 207 and the sealing semicircular sleeve two 211. Both conductor contact plates 307 are slidably connected to... Inside the assembly tube 301, the bottom of the fuse 304 contacts the top of the connecting conductor 305. The tops of the two upper conductor contact plates 307 contact the bottoms of both ends of the coil winding 5, respectively. The bottom of the lower conductor contact plate 307 contacts the top of the fuse 304. The bottom of the connecting conductor 305 is fixedly connected to the top of the metal conductor 302. The plug plate 308 is plugged into the fixing ear 303. When current flows through the metal conductor 302 and the connecting conductor 305 to the fuse 304, if the current is too large, the fuse 304 will melt, thus protecting the coil winding 5. When there is no overload, the current can be transmitted through the fuse 304 to the conductor contact plate 307, the conductor spring 306, and the coil winding 5. This allows the inductor to function. When fuse 304 blows and needs replacement, first press the plug plate 308 towards the assembly cylinder 301, and then move the assembly cylinder 301 downwards. This allows the fixing lug 303 to move out of the plug plate 308. At this point, the assembly cylinder 301 can be removed from the end of the coil winding 5. Invert the assembly cylinder 301. First, the conductor spring 306 and the two conductor contact plates 307 will slide out from the inside of the assembly cylinder 301. Then, the fuse 304 will slide out from the inside of the assembly cylinder 301, allowing the blown fuse 304 to be removed from the inside of the assembly cylinder 301. Then, reset the assembly cylinder 301 and insert the new fuse 304 into the inside of the assembly cylinder 301.The conductor spring 306 and conductor contact plate 307 are then placed back into the assembly cylinder 301. The top of the assembly cylinder 301 is then inserted into the end of the coil winding 5. The end of the coil winding 5 pushes the upper conductor contact plate 307 downwards, compressing the conductor spring 306. Simultaneously, the plug plate 308 is inserted into the fixing ear 303 and engages with it, thus mounting the assembly cylinder 301 onto the end of the coil winding 5. The reaction force of the conductor spring 306 exerts a downward force on the lower conductor contact plate 307, compressing it and ensuring good contact between the bottom of the conductor contact plate 307 and the connecting conductor 305, facilitating energization.

[0024] Working principle: When installing the magnetic core 4 and coil winding 5 inside the protective housing 1, first fold up one end of the coil winding 5 and place the magnetic core 4 and coil winding 5 inside the protective housing 1. Then, reset one end of the coil winding 5. Next, align the sealing semicircular sleeve 207 on the assembly jacket 201 with the sealing semicircular sleeve 211 on the fixing mounting ring 209, and insert the sealing strip 208 into the sealing splicing groove 212. At this time, push the mounting plate 204, using the mounting plate 20... 4. The spring 203 is compressed, and the elastic insert 205 is inserted into the insertion slot 210. The inclined insert 206 passes through the insertion slot 210. Since the side of the inclined insert 206 away from the mounting plate 204 is inclined, and the elastic insert 205 is elastic, when the inclined insert 206 contacts the inner wall of the insertion slot 210, it will exert a force on the protective shell 1 and bend the elastic insert 205. After the inclined insert 206 passes through the insertion slot 210, The elastic insert 205 is elastically reset, which allows the inclined insert 206 to move and reset away from the protective housing 1. This allows the inclined insert 206 to engage with the outside of the fixed mounting ring 209. At this time, the reaction force of the mounting spring 203 can exert a force on the mounting plate 204 away from the protective housing 1. However, under the action of the elastic insert 205 and the inclined insert 206, the mounting plate 204 will not move. Then, the reaction force of the mounting spring 203 can be applied to the assembly sleeve 201, so that the assembly sleeve 201 is tightly inserted into the inside of the fixed mounting ring 209. This allows the two ends of the magnetic core 4 to be stably set inside the two mounting slots 202. At the same time, when the two ends of the protective housing 1 are subjected to impact force, the mounting plate 204 can exert a force on the mounting spring 203 again and use the mounting spring 203 to dissipate the impact force, thereby reducing the impact force generated by the impact and protecting the magnetic core 4 and coil winding 5 inside the protective housing 1. When replacing the magnetic core 4 and coil winding 5 or the protective shell 1, press the elastic insert 205 toward the mounting spring 203, thereby moving the inclined insert 206 toward the protective shell 1. At this time, the end of the inclined insert 206 and the elastic insert 205 away from the mounting plate 204 can be pulled out of the insertion slot 210, thereby removing the assembly jacket 201 from both ends of the protective shell 1. Then, one end of the coil winding 5 can be folded up, and the magnetic core 4 and coil winding 5 can be pulled out from the inside of the protective shell 1, thus completing the disassembly of the magnetic core 4 or the coil winding 5. At this time, the protective shell 1 or the magnetic core 4 and coil winding 5 can be replaced. When current flows through the metal conductor 302 and connecting conductor 305 into the fuse 304, excessive current will cause the fuse 304 to blow, thus protecting the coil winding 5. When there is no overload, the current can be transmitted through the fuse 304 to the conductor contact plate 307, conductor spring 306, and coil winding 5, allowing the inductor to function. When the fuse 304 blows and needs replacement, first press the plug plate 308 towards the assembly cylinder 301 and move the assembly cylinder 301 downwards, allowing the fixing ear 303 to move out of the plug plate 308. Then, the assembly cylinder 301 can be removed from the end of the coil winding 5. Inverting the assembly cylinder 301 will cause the conductor spring 306 and the two conductor contact plates 307 to slide out from inside the assembly cylinder 301, followed by the fuse 304 sliding out from inside the assembly cylinder 301, thus preventing the fuse from blowing. After removing the fuse 304 from the assembly cylinder 301, the assembly cylinder 301 is reset. The new fuse 304 is then placed inside the assembly cylinder 301, and the conductor spring 306 and conductor contact plate 307 are placed inside the assembly cylinder 301 again. The top of the assembly cylinder 301 is then inserted into the end of the coil winding 5. The end of the coil winding 5 will push the upper conductor contact plate 307 downward, thereby compressing the conductor spring 306. At the same time, the plug plate 308 will be inserted into the fixing ear 303 and engage with the fixing ear 303, thus allowing the assembly cylinder 301 to be installed at the end of the coil winding 5. Meanwhile, the reaction force of the conductor spring 306 will exert a downward force on the lower conductor contact plate 307, thereby squeezing the conductor contact plate 307 and ensuring good contact between the bottom of the conductor contact plate 307 and the connecting conductor 305, thus facilitating energization.
