Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electromagnetic coils, in particular to a high-protection electromagnetic coil. BACKGROUND

[0002] An electromagnetic coil is an important electrical component that uses the magnetic field generated by electric current to produce inductance. Its working principle is based on Faraday's law. The magnetic field generated in the coil is proportional to the current intensity and the number of turns. Electromagnetic coils are widely used in household appliances, instruments and other electronic products, mainly for electromagnetic induction, signal isolation and filtering.

[0003] In the fields of industrial equipment, automotive electronics, power systems, etc., electromagnetic coils are the core components for electromagnetic conversion. Their working stability and service life directly affect the overall equipment efficiency. Traditional electromagnetic coils are mainly supported by the skeleton. The coil is prone to looseness, displacement, and even deformation due to external pressure and collision, resulting in coil turn disorder, electromagnetic parameter deviation, and direct impact on electromagnetic conversion efficiency. Moreover, the existing electromagnetic coils have obvious defects in fixing and maintenance, making them difficult to install or replace. Long-term use can cause the wire to loosen and slip due to vibration, causing the coil to lose power or have poor contact.

[0015] As a further embodiment of the present invention, the protective cover is made of ceramic material, and a high-strength TPU sealing gasket is machined around the bottom of the protective cover.

[0016] The beneficial effects of the present invention are: (1) Through the cooperation of the support mechanism, a double-sided clamping structure is formed, which directly avoids the coil body from being squeezed and deformed by external force. At the same time, the spring reset rod and the slider work together to buffer the impact. With the rubber protective layer on the inner side of the buckle plate and the outer side of the inner lining plate, the damage caused by the impact and vibration is further reduced.

[0017] (2) The protective mechanism extracts air from the protective cover and fills it with inert gas through the air extraction valve. This can not only isolate oxygen to prevent the coil and frame from oxidizing and rusting, but also suppress corona discharge and improve insulation performance. The ceramic protective cover, combined with the high-strength TPU sealing gasket at the bottom, can effectively block the intrusion of external dust and moisture. The left clamp and right buckle plate wrap the bottom plate to prevent the fixing mechanism from being hit by external impacts, forming a complete all-round physical protection closed loop.

[0018] (3) The installation, disassembly and maintenance process of the electromagnetic coil is greatly simplified by the operation of the fixing mechanism, and the operation efficiency is significantly improved. When installing the frame, it is only necessary to insert the slot block to fix it through double snap-fit. When disassembling, the buckle can be turned to quickly separate it. The entire process is tool-free. The wire end clamping component is made of the cooperation of the sliding frame, the plug and the support spring. Pressing the sliding frame can expand the clamp tube to facilitate wire insertion. After releasing, it can automatically clamp the wire end. The double anti-dislodgement design of the clamp and the locking protrusion ensures the connection is stable and simplifies the wiring steps, shortening the overall disassembly and maintenance time.

[0019] (4) Through the cooperation of the above mechanisms, the core function of the coil and the stability of operation are taken into account while ensuring the protection effect. It is applicable to a wide range of scenarios. In terms of operational reliability, the fixing mechanism avoids loosening or falling off due to vibration during long-term use by double snapping of the skeleton and double clamping of the wire end, reducing connection failures. The ceramic protective cover of the protection mechanism not only does not hinder the penetration of magnetic lines of force, ensuring the efficient performance of the electromagnetic function of the coil, but also has excellent thermal conductivity, which can quickly dissipate working heat and prevent the coil from overheating and decaying or burning out. This makes it suitable for both conventional environments and complex industrial scenarios with dust, humidity and high-frequency vibration. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figure 1 and Figures 7-13As shown, the present invention is a high-protection electromagnetic coil, including a frame 1, which supports the coil body 2. The coil body 2 is wound around the outer wall of the frame 1. A support mechanism 3 is provided on the outer side of the coil body 2. The support mechanism 3 is used to support and protect the outer wall of the coil body 2. A fixing mechanism 4 is provided at the bottom of the frame 1. The fixing mechanism 4 is used to quickly clamp and fix the wire ends of the frame 1 and the coil body 2. A protective mechanism 5 is provided on the outer side of the support mechanism 3 and the fixing mechanism 4. The protective mechanism 5 is used to provide all-round protection for the support mechanism 3 and the fixing mechanism 4 to prevent them from being bumped.

[0036] The support mechanism 3 includes a right buckle plate 301, which is used to fix the support plate 304. A left buckle plate 302 is provided on the left side of the right buckle plate 301. The left buckle plate 302, through its cooperation with the right buckle plate 301, can wrap the outer wall of the coil body 2 inside, thereby protecting the outer side of the coil body 2. Multiple fixing ears 303 are fixed in a circular array at equal intervals on the outer side of the left buckle plate 301 and the right side of the left buckle plate 302. The fixing ears 303 are used to lock the right buckle plate 301 and the left buckle plate 302 together with bolts, and each pair of bolts... The fitting fixing ears 303 are connected together by bolts and threads. A support plate 304 is fixedly connected to the inside of the right side of the right buckle plate 301. The support plate 304 supports the support rod 307 and allows the slider 306 to slide inside it. Multiple spring return rods 305 are arranged in a circular array at equal intervals inside the left side of the support plate 304. The spring return rods 305 support and return the slider 306. A slider 306 is fixedly connected to the outside of each spring return rod 305. The slider 306 is used to fix and support the inner lining plate 311. A support rod 307 is rotatably connected to the center of the left side of 04. The support rod 307 supports the turntable 308. The turntable 308 is fixed to the left side of the support rod 307. The turntable 308 supports the inner side of the arc-shaped connecting rod 309 and can drive the inner side of the arc-shaped connecting rod 309 to move. Arc-shaped connecting rods 309 are rotatably connected to the four outer corners of the turntable 308. The arc-shaped connecting rods 309 drive the adapter 310 to move. Adapters 310 are rotatably connected to the outer sides of multiple arc-shaped connecting rods 309. Adapters 310 drive the inner lining plate 31. 1. The coil body 2 is moved. Each adapter 310 has an inner liner 311 fixed to its outer side. The inner liner 311 is used to support and protect the inner side of the coil body 2. A knob 312 is fixed to the center of the left side of the turntable 308. The knob 312 is used to drive the turntable 308 to rotate. The right buckle 301 is fastened to the right side of the outer wall of the coil body 2, and the left buckle 302 is fastened to the left side of the outer wall of the coil body 2. The outer sides of multiple inner liner 311 are attached to the inner wall of the coil body 2. The left side of each slider 306 is fixedly connected to the right side of the inner liner 311 it is attached to.

[0037] In this embodiment, preferably, multiple slides are arranged in a circular array at equal intervals on the left side of the support disk 304, and the right sides of multiple sliders 306 are respectively slidably connected to the interior of the corresponding slides. The slides are used to limit the movement trajectory of the sliders 306.

[0038] In this embodiment, preferably, the inner sides of the right buckle plate 301 and the left buckle plate 302, as well as the outer side of the inner bushing, are covered with a layer of rubber material to enhance the protection effect on the coil body 2 and to effectively buffer the impact force on the coil body 2 when it is subjected to an impact.

[0039] In summary, the support mechanism 3 provides support and protection for the coil body 2 from both the inside and outside, preventing deformation or damage during use. When the coil body 2 needs to be installed or removed, simply turn the knob 312. The knob 312 drives the turntable 308 to rotate, which in turn causes the arc-shaped connecting rod 309 to move the adapter 310 and the inner liner plate 311, thus loosening or clamping the coil body 2. The operation is simple and convenient. At the same time, the cooperation of the spring return rod 305 and the slider 306 allows the inner liner plate 311 to automatically return to its original position after movement, improving the convenience of use. Furthermore, when the coil body 2 is subjected to impact or collision and shakes, the cooperation of the spring return rod 305, the slider 306, and the inner liner plate 311 can reduce the impact on the coil body 2 and prevent damage to the coil body 2.

[0040] Example 2, please refer to Figures 4-6As shown, based on Embodiment 1, the fixing mechanism 4 includes a base plate 401, which is used to fix the groove block 402 and the wire clamping member 408. The groove block 402 is fixedly connected to the top center of the base plate 401. The groove block 402 is used to snap the bottom of the frame 1. Wedge blocks 403 are symmetrically fixed to the left and right sides of the top center of the groove block 402. The wedge blocks 403 are used to assist the groove block 402 in snapping and supporting the bottom of the frame 1. The front and rear ends of the groove block 402 are both fixedly connected to the shaft rod 404. The shaft rod 404 is used to support the L-shaped buckle 405, so that the L-shaped buckle 405 can rotate around the shaft rod 404. The outer wall of each shaft rod 404 is rotatably connected to an L-shaped buckle 405. 05. L-shaped buckles 405 are used to fix protrusions 406 and plugs 407. Protrusions 406 are fixed to the bottom inner side of both L-shaped buckles 405. Protrusions 406 are used to snap the bottom of the frame 1. Multiple plugs 407 are fixed to the top inner side of both L-shaped buckles 405. Plugs 407 are used to snap the front and rear ends of the bottom of the frame 1. Wire end clamping components 408 are provided at the front and rear ends of the inner side of the base plate 401. Wire end clamping components 408 are used to clamp and fix the wire ends at the bottom of the coil body 2, making it easy to connect the coil to the outside. The bottom end of the frame 1 is inserted into the top of the slot 402. The two L-shaped buckles 405 are symmetrical about the central axis of the slot 402.

[0041] In this embodiment, preferably, slots are provided at both the front and rear ends of the bottom of the frame 1, and symmetrical grooves adapted to the specifications of the protrusion 406 are provided on the front and rear sides of the bottom of the frame 1. The plug 407 can be inserted into the slot, and the protrusion 406 can be fitted into the groove. Through the mutual cooperation of the L-shaped buckle 405, the protrusion 406, and the plug 407, when the bottom of the frame 1 is inserted into the top of the slot 402, the groove at the bottom of the frame 1 will fit together with the protrusion 406 first, and after the groove and the protrusion 406 are fully fitted together, the originally light The slightly outward-curving L-shaped buckle 405 is pressed in place, allowing the plug 407 to be inserted into the slot, making the bottom of the frame 1 more tightly engaged with the slot block 402. Conversely, if the frame 1 needs to be pulled out of the slot block 402, the L-shaped buckle 405 needs to be moved outward first. When the L-shaped buckle 405 is moved, the plug 407 will first disengage from the slot, and while the L-shaped buckle 405 is being moved, the protrusion 406 will push the frame 1 upward, thus separating the frame 1 from the slot block 402, facilitating quick installation or removal of the frame 1.

[0042] In this embodiment, preferably, the wire end clamping member 408 includes a sleeve 4081, which supports the clamping tube 4082 and fixes the locking protrusion 4087. Two clamping tubes 4082 are symmetrically fixed to the top of the sleeve 4081. The clamping tubes 4082 are used to clamp and fix the wire end of the coil body 2. Multiple clamping blocks 4083 are equidistantly fixed to the inner walls of the two clamping tubes 4082 in a circular array. The clamping blocks 4083 are used to enhance the clamping force of the clamping tubes 4082 on the wire end and prevent the wire end from slipping off the inner side of the clamping tubes 4082. Insert blocks 4084 are slidably connected to the top inner sides of the two clamping tubes 4082. The insert blocks 4084 are used to separate the clamping blocks 4083. A sliding frame 4085 is fixed to the outer side of the insert block 4084. The frame 4085 is used to move the insert block 4084. The bottom of the sliding frame 4085 is fixedly connected to the support spring 4086, which is used to reset the sliding frame 4085. The inner wall of the sleeve 4081 is fixedly connected to multiple locking protrusions 4087 in a ring array at equal intervals. The locking protrusions 4087 are used to clamp the bottom of the outer wall of the wire end, which can also prevent the wire end from slipping out of the inside of the sleeve 4081. The sleeve 4081 is fixedly connected to the front and rear ends of the bottom plate 401. The bottom of the support spring 4086 is fixedly connected to the top outside of the sleeve 4081. The two wire ends at the bottom of the coil body 2 are respectively inserted into the inside of the two wire end clamping members 408. The inner sides of the multiple clamping blocks 4083 and the multiple locking protrusions 4087 are all tightly fastened to the outer side of the wire end.

[0043] In this embodiment, preferably, wedge-shaped cavities are symmetrically provided on the outer side of the bottom of the two clamping tubes 4082. By setting the wedge-shaped cavities, when the insert block 4084 slides down, space can be reserved for the clamping tubes 4082 to move outward, so as to avoid the clamping tubes 4082 from breaking when they expand outward.

[0044] In summary, the fixing mechanism 4 enables quick clamping and fixing of the wire ends of the frame 1 and the coil body 2. When installing the frame 1, its bottom end is inserted into the top of the slot 402. The L-shaped buckle 405, the protrusion 406, and the plug 407 work together to ensure a tight fit between the frame 1 and the slot 402. During disassembly, the L-shaped buckle 405 can be easily moved to separate the wire ends. For the wire ends of the coil body 2, the clamping block 4083 and locking protrusion 4087 in the wire end clamping component 408 effectively prevent the wire ends from slipping. The wedge-shaped cavity design ensures that the clamping tube 4082 will not be damaged when the insertion block 4084 slides. After inserting the frame 1 and the slot 402 together, the sliding frame 4085 in the wire end clamping component 408 is pressed downwards. The sliding frame 4085 moves the insertion block 4084 along with the frame, thus securing the wire ends during insertion. As block 4084 slides downward, it squeezes the inner sides of the two clamping tubes 4082, causing the clamping tubes 4082 to expand outward. This facilitates the insertion of the wire end of the coil body 2 into the sleeve 4081. After the wire end is inserted, the slide frame 4085 is released. The rebound force generated when the support spring 4086 is compressed under force can reset the slide frame 4085. The slide frame 4085 then drives the insertion block 4084 to slide back to the top of the clamping tube 4082. Under the elasticity of the clamping tube 4082 itself, the clamping tube 4082 will clamp the outer wall of the wire end. The entire fixing mechanism 4 is easy to operate, improves the efficiency of installing and disassembling the coil body 2, and ensures the stability of the connection. This makes the electromagnetic coil more reliable during use and avoids failures caused by loosening or falling off.

[0045] Example 3, please refer to Figures 1-3As shown, based on Embodiment 1 and Embodiment 2, the protective mechanism 5 includes a left clamping plate 501, and a right clamping plate 502 is provided on the right side of the left clamping plate 501. The left clamping plate 501 and the right clamping plate 502 can be fastened to the left and right sides of the base plate 401 respectively. This completely encloses the base plate 401. A fixing plate 503 is provided on the inner side of the left clamping plate 501 and the right clamping plate 502. The fixing plate 503 is used to fix and support the air extraction valve 505 and the air inflation valve 506, and can be connected to the left clamping plate 501 and the right clamping plate 502 via connecting pieces 504. Connecting pieces 504 are bolted to the bottom of the fixing plate 503 at positions adjacent to the left clamping plate 501 and the right clamping plate 502. The connecting pieces 504 are used to connect and fix the left clamping plate 501, the right clamping plate 502, and the fixing plate 503 together. An air extraction valve 505 is located at the center of the bottom of the front fixing plate 503, and a valve is located at the bottom of the rear fixing plate 503. An inflation valve 506 is provided at the center. Through the cooperation of the air extraction valve 505 and the inflation valve 506, after the protective cover 507 is threaded to the top of the left clamping plate 501, the fixing plate 503 and the right clamping plate 502, the air remaining inside the protective cover 507 can be extracted through the air extraction valve 505. After the air is extracted, inert gas is filled into it through the inflation valve 506, thereby preventing internal oxidation and corona discharge. The top of the left clamping plate 501, the right clamping plate 502 and the fixing plate 503 are connected to the protective cover 507 by bolts. The left clamping plate 501 and the right clamping plate 502 are respectively fastened to the left and right sides of the base plate 401. The protective cover 507 is sleeved on the outside of the support mechanism 3.

[0046] In this embodiment, preferably, the protective cover 507 is made of ceramic material. Ceramic is an excellent heat conductor, which can improve the heat dissipation effect while ensuring that the magnetic lines of force can penetrate efficiently without affecting the operation of the coil. In addition, a high-strength TPU sealing gasket is processed at the bottom of the protective cover 507 to enhance the sealing performance of the protective cover 507.

[0047] In summary, the protective mechanism 5 provides comprehensive protection for the support mechanism 3 and the fixing mechanism 4. Firstly, the left clamping plate 501 and right clamping plate 502 enclose the base plate 401, preventing it from being bumped or damaged by external forces. Secondly, the air extraction valve 505 and air filling valve 506 fill the protective cover 507 with inert gas, preventing internal oxidation and corona discharge, and extending the service life of the electromagnetic coil. Simultaneously, the ceramic protective cover 507 not only improves heat dissipation but also ensures efficient penetration of magnetic lines of force without affecting the normal operation of the coil. The high-strength TPU sealing gasket at the bottom further enhances the sealing performance of the protective cover 507, effectively preventing the intrusion of external dust and moisture. Furthermore, the protective mechanism 5, together with the support mechanism 3 and the fixing mechanism 4, forms a complete protective system, enabling the high-protection electromagnetic coil to operate stably and reliably in complex working environments. This reduces malfunctions and damage caused by external factors, improves the overall performance and safety of the electromagnetic coil, and provides strong support for the stable operation of the equipment.

[0048] Example 4, please refer to Figures 1-13 As shown, this embodiment combines Embodiment 1, Embodiment 2, and Embodiment 3. When the electromagnetic coil is installed, the support mechanism 3 is first used to provide internal and external support and protection for the coil body 2. The right buckle plate 301 is then fastened to the right side of the outer wall of the coil body 2. At the same time, the knob 312 is rotated, causing the turntable 308 to rotate. This causes the arc-shaped connecting rod 309 to move the adapter 310 and the inner lining plate 311, allowing the inner lining plate 311 to retract towards the axis of the turntable 308. This allows the inner lining plate 311 to be located inside the coil body 2 and connected to the coil. When the inner sides of the main body 2 are aligned, the knob 312 is released. Through the operation of the spring return rod 305, the slider 306 is driven to return to its original position, thereby allowing the inner liner 311 to fit against the inner side of the coil main body 2. Then, the left buckle 302 is fastened to the left side of the coil main body 2. The left buckle 302 and the right buckle 301 are tightly joined by the bolt connecting the fixing ear 303, clamping the coil main body 2. The spring return rod 305 and the slider 306 work together to ensure that the inner liner 311 automatically resets after movement and can reduce the impact force when subjected to impact.

[0049] Next, the fixing mechanism 4 is used to fix the wire ends of the frame 1 and the coil body 2. The bottom end of the frame 1 is inserted into the top of the slot 402. The L-shaped buckle 405, the protrusion 406 and the plug 407 work together to make the frame 1 and the slot 402 tightly connected. For the wire ends of the coil body 2, the sliding frame 4085 is pressed to make the insert 4084 squeeze the clamp tube 4082 to expand. After inserting the wire ends, the sliding frame 4085 is released. The clamp tube 4082 clamps the wire ends under its own elasticity and the rebound force of the support spring 4086. The clamp 4083 and the locking protrusion 4087 prevent the wire ends from slipping off.

[0050] After the frame 1 and coil body 2 are installed together with the fixing mechanism 4, the left clamping plate 501 and the right clamping plate 502 are fastened to the left and right sides of the base plate 401 respectively. The fixing plate 503 is connected to the left clamping plate 501 and the right clamping plate 502 by the connecting piece 504 and bolts. Then, the protective cover 507 is fastened to the outside of the support mechanism 3 and connected to the top of the left clamping plate 501, the fixing plate 503 and the right clamping plate 502 by bolt threads. The coil body 2 can then be fitted into the inside of the protective mechanism 5. At this time, the air is extracted from the protective cover 507 by the air extraction valve 505 and then filled with inert gas by the air filling valve 506, which can effectively prevent internal oxidation and corona discharge.

[0051] Through the coordinated operation of the support mechanism 3, the fixing mechanism 4, and the protective mechanism 5, the electromagnetic coil can be effectively resisted from vibration and impact, preventing deformation or damage to the coil body 2. The fixing mechanism 4 ensures the stability of the connection between the frame 1 and the wire end, avoiding malfunctions caused by loosening. The protective mechanism 5 prevents internal oxidation and corona discharge, while blocking the intrusion of external dust and moisture. Moreover, the ceramic protective cover 507 improves heat dissipation while ensuring efficient penetration of magnetic lines of force, ensuring the normal operation of the electromagnetic coil and providing strong support for the stable operation of the entire device. This improves the overall performance and safety of the electromagnetic coil and reduces malfunctions and damage caused by external factors.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
