Description
Technical Field
[0001] This utility model relates to the field of electrical component technology, and in particular to a magnetic core with anti-adhesion and shock-resistant functions. Background Technology
[0002] In the existing technology, the fixing method of magnetic core, as an important component in electronic devices, has many problems.
[0003] Typically, magnetic cores are fixed to the frame using glue and tape, which greatly inconveniences workers when disassembling and replacing parts during equipment maintenance. In addition, magnetic cores often need to be fixed to the circuit board by welding. However, the equipment generates high temperatures during operation, and excessively high temperatures can melt the plastic material on the surface of the magnetic core, causing the magnetic core to adhere tightly to the circuit board. This not only increases the maintenance cost of the equipment but also increases the risk of failure, seriously affecting the normal operation and service life of the equipment.
[0004] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: since the magnetic core is fixed to the frame using glue and tape, it is not conducive to timely disassembly and replacement of parts by maintenance personnel. The magnetic core often needs to be fixed to the circuit board by welding. During operation, high temperatures are generated, and excessively high temperatures can melt the plastic material on the surface of the magnetic core, causing the magnetic core to adhere tightly to the circuit board, increasing the maintenance cost and failure risk of the equipment. Therefore, to address the above problems, a magnetic core with anti-adhesion and shock-resistant functions is proposed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where the magnetic core is fixed to the frame primarily with glue and tape, making it difficult for maintenance personnel to disassemble and replace parts promptly. Furthermore, the magnetic core often needs to be fixed to the circuit board by welding, which generates high temperatures during operation. Excessive heat can melt the plastic material on the surface of the magnetic core, causing it to adhere tightly to the circuit board, increasing maintenance costs and the risk of failure. Therefore, this invention proposes a magnetic core with anti-adhesion and shock-resistant functions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic core with anti-adhesion and anti-vibration functions, comprising a skeleton, a right magnetic core and a left magnetic core slidably connected to the inner surface of the skeleton, a fixing device provided on both sides of the right magnetic core, the fixing device comprising two fixing blocks, a fixing rod fixedly connected to the side of the fixing blocks that are close to each other, a fixing plate rotatably connected to the arc surface of the fixing rod, a sliding hole opened on the surface of the fixing plate, two sliding rods slidably connected to the inner wall of the sliding hole, a moving hole opened on the surface of the fixing plate, a moving block slidably connected to the inner wall of the moving hole, one side of the moving block being fixedly connected to the arc surface of the sliding rod, two elliptical blocks fixedly connected to the surface of the left magnetic core, a slot opened on the surface of the elliptical blocks, and a high-temperature resistant layer fixedly connected to both sides of the right and left magnetic cores.
[0007] The effect achieved by the above components is that the frame can be quickly removed by setting up a fixing device. During use, since the magnetic core is fixed to the frame with glue and tape, it is not conducive to the timely disassembly and replacement of parts by the staff during maintenance. The magnetic core often needs to be fixed to the circuit board by welding. During operation, high temperatures are generated. Excessive temperature will melt the plastic material on the surface of the magnetic core, causing the magnetic core to stick tightly to the circuit board, increasing the maintenance cost and failure risk of the equipment.
[0008] Preferably, the arc surface of the fixing rod is fitted with a torsion spring, and the two ends of the torsion spring are fixedly connected to the fixing plate and the fixing block, respectively.
[0009] The effect achieved by the above components is that, through the cooperation of the torsion spring fixing plate and the fixing block, when the slide rod moves away from the elliptical block slot, the torsion spring itself can automatically open when the operator releases the fixing plate.
[0010] Preferably, a spring is fixedly connected to one end of the two slide rods that are close to each other, and the size of the elliptical block slot is adapted to the size of the slide rod.
[0011] The effect achieved by the above components is that, through the cooperation of the sliding spring and the elliptical block slot, when the user releases the moving block, the spring's own elastic force drives the sliding rod to automatically insert into the inner wall of the elliptical block slot, thus improving the stability of the device.
[0012] Preferably, rubber pads are fixedly connected to both sides of the right and left magnetic cores.
[0013] The effect achieved by the above components is that, through the cooperation of the rubber pads, the left and right magnetic cores can be prevented from being affected by external vibrations, thus preventing damage to the magnetic cores.
[0014] Preferably, the surface of the frame is provided with a ventilation device, the ventilation device including a hollow plate, the hollow plate being fixedly connected to the surface of the frame, the surface of the hollow plate having a plurality of air holes, a large-end rod being fixedly connected to the surface of the hollow plate, a rotating plate being rotatably connected to the arc surface of the large-end rod, a screw being slidably inserted into the surface of the rotating plate, a threaded groove being formed on the surface of the hollow plate, and a ventilation plate being slidably connected to the inner surface of the hollow plate.
[0015] The effect achieved by the above components is as follows: by setting up a ventilation device, the circuit board can be cooled. During use, when the circuit board is running for a long time or under rated load, the circuit board will consume more electrical energy to drive the load, thereby generating more heat. If the extra heat cannot be effectively dissipated, the temperature inside the core will rise. The excessively high temperature will cause the plastic material on the surface of the magnetic core to melt. The melted plastic will cause the magnetic core to stick tightly to the circuit board. This adhesion will not only affect the normal working performance of the magnetic core.
[0016] Preferably, two L-shaped plates are fixedly connected to the surface of the hollow plate, and the size of the L-shaped plates is adapted to the size of the ventilation plate.
[0017] The effect achieved by the above components is that, through the cooperation of the L-shaped hollow plate and the ventilation plate, the ventilation plate can be quickly positioned inside the hollow plate during installation, which facilitates installation.
[0018] Preferably, the surface of the ventilation plate is provided with a groove, and the size of the groove is adapted to the size of the screw.
[0019] The effect achieved by the above components is that, through the cooperation of the ventilation plate and the pull groove, it is convenient for workers to pull out the ventilation plate when replacing it.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] 1. In this utility model, by setting a fixing device, the effect of quick disassembly of the frame is achieved. In the process of use, since the magnetic core is fixed to the frame, it is basically fixed with glue and tape, which is not conducive to the timely disassembly and replacement of parts by the staff during maintenance. The magnetic core often needs to be fixed to the circuit board by welding. During the operation, a high temperature is generated. The excessively high temperature will melt the plastic material on the surface of the magnetic core, causing the magnetic core to be tightly bonded to the circuit board, increasing the maintenance cost and failure risk of the equipment.
[0022] 2. In this utility model, by setting a ventilation device, the circuit board can be cooled. During use, when the circuit board is running for a long time or under rated load, the circuit board will consume more electrical energy to drive the load, thereby generating more heat. It is impossible to effectively dissipate the extra heat, which will cause the temperature inside the skeleton to rise. The excessively high temperature will cause the plastic material on the surface of the magnetic core to melt. The melted plastic will cause the magnetic core to stick tightly to the circuit board. This adhesion will not only affect the normal working performance of the magnetic core. Attached Figure Description

[0030] Reference Figure 1As shown, this utility model provides a technical solution: a magnetic core with anti-adhesion and shock-resistant functions, including a frame 5. A right magnetic core 1 and a left magnetic core 2 are slidably connected to the inner surface of the frame 5. Fixing devices 3 are provided on both sides of the right magnetic core 1. By setting the fixing devices 3, the frame 5 can be quickly removed. In use, since the magnetic core is fixed to the frame 5, it is basically fixed with glue and tape, which is not conducive to the timely disassembly and replacement of parts by the staff during maintenance. The magnetic core often needs to be fixed to the circuit board by welding. During operation, a high temperature is generated. The excessively high temperature will melt the plastic material on the surface of the magnetic core, causing the magnetic core to stick tightly to the circuit board, increasing the maintenance cost and failure risk of the equipment. The surface of the frame 5 is equipped with a ventilation device 4. By setting the ventilation device 4, the circuit board can be cooled. During use, when the circuit board is running for a long time or under rated load, the circuit board will consume more electrical energy to drive the load, which will generate more heat. If the extra heat cannot be effectively dissipated, the temperature inside the frame 5 will rise. The excessive temperature will cause the plastic material on the surface of the magnetic core to melt. The melted plastic will cause the magnetic core to stick tightly to the circuit board. This adhesion will not only affect the normal working performance of the magnetic core.
[0031] The following section will describe the specific setup and function of its fixing device 3 and ventilation device 4.
[0032] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the fixing device 3 includes two fixing blocks 301. A fixing rod 302 is fixedly connected to one side of the fixing blocks 301 that is close to each other. A fixing plate 303 is rotatably connected to the arc surface of the fixing rod 302. A sliding hole 304 is opened on the surface of the fixing plate 303. Two sliding rods 305 are slidably connected to the inner wall of the sliding hole 304. A moving hole 306 is opened on the surface of the fixing plate 303. A moving block 307 is slidably connected to the inner wall of the moving hole 306. One side of the moving block 307 is fixedly connected to the arc surface of the sliding rod 305. Two elliptical blocks 308 are fixedly connected to the surface of the left magnetic core 2. A slot is opened on the surface of the elliptical blocks 308. High-temperature resistant layers 309 are fixedly connected to both sides of the right magnetic core 1 and the left magnetic core 2. A torsion spring 310 is sleeved on the arc surface of the fixing rod 302. The two ends of the torsion spring 310 are respectively connected to the fixing plate 303 and the fixing block 302. 1. Fixed connection: Two sliding rods 305 are fixedly connected to springs 311 at their close ends. The size of the elliptical block 308 slot is adapted to the size of the sliding rod 305. Rubber pads 312 are fixedly connected to both sides of the right magnetic core 1 and the left magnetic core 2. Through the cooperation of the torsion spring 310, the fixing plate 303, and the fixing block 301, when the sliding rod 305 moves away from the elliptical block 308 slot, the torsion of the torsion spring 310 itself allows the operator to automatically open it when the fixing plate 303 is released. Through the cooperation of the sliding rod 305, spring 311, and elliptical block 308 slot, when the user releases the moving block 307, the spring 311 itself causes the sliding rod 305 to automatically insert into the inner wall of the elliptical block 308 slot, improving the stability of the device. The cooperation of the rubber pads 312 can prevent the left magnetic core 2 and the right magnetic core 1 from being affected by external vibrations, thus preventing damage to the magnetic cores.
[0033] Reference Figure 5 ,and Figure 6 As shown, specifically, the ventilation device 4 includes a hollow plate 41, which is fixedly connected to the surface of the frame 5. Several air holes 42 are formed on the surface of the hollow plate 41. A large-end rod 43 is fixedly connected to the surface of the hollow plate 41. A rotating plate 44 is rotatably connected to the arc surface of the large-end rod 43. A screw 45 is slidably inserted into the surface of the rotating plate 44. A threaded groove 46 is formed on the surface of the hollow plate 41. A ventilation plate 47 is slidably connected to the inner surface of the hollow plate 41. Two L-shaped plates 48 are fixedly connected to the surface of the hollow plate 41. The dimensions of the L-shaped plates 48 are adapted to the dimensions of the ventilation plate 47. A groove 49 is formed on the surface of the ventilation plate 47. The dimensions of the threaded groove 46 are adapted to the dimensions of the screw 45. Through the cooperation of the L-shaped plates 48, the hollow plate 41, and the ventilation plate 47, the ventilation plate 47 can be quickly positioned inside the hollow plate 41 during installation, facilitating installation. Through the cooperation of the ventilation plate 47 and the groove 49, it is convenient for workers to pull out the ventilation plate 47 when replacing it.
[0034] Working principle: When the worker needs to dismantle, the worker presses the movable blocks 307 on both sides. The movable blocks 307 slide on the inner wall of the movable hole 306. The movable blocks 307 drive the sliding rod 305. The sliding rod 305 slides on the inner wall of the sliding hole 304. At this time, the spring 311 is in a contracted state. The sliding rod 305 moves away from the inner wall of the slot of the elliptical block 308. At this time, due to the torsion of the torsion spring 310 itself, the fixing plate 303 is driven to rotate. The fixing plate 303 rotates on the arc surface of the fixing rod 302, thereby completing the dismantling.
[0035] Working principle: When the worker needs to replace the ventilation plate 47, the worker rotates the screw 45, which rotates inside the rotating plate 44. The screw 45 rotates away from the inner wall of the threaded groove 46. The worker rotates the rotating plate 44, which rotates on the arc surface of the big end rod 43. The worker then pulls out the ventilation plate 47 by engaging the pull groove 49. The worker then places the new ventilation plate 47 on the surface of the L-shaped plate 48 and pushes it directly into the hollow plate 41. The worker then flips the rotating plate 44 back to its original position and rotates the screw 45, which reconnects with the threaded groove 46, thus completing the installation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
