Description

Technical Field

[0001] This utility model belongs to the field of inductor technology, and specifically relates to an inductor mounting bracket. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance; it only impedes changes in current.

[0003] In the field of electronic equipment manufacturing, inductors are key components, and the reliability of their mounting and fixing methods directly affects the stability and lifespan of the entire device. Traditional inductor mounting commonly uses direct bolt fastening or simple snap-fit ​​structures, which have significant limitations. First, rigid connections lack necessary buffering, easily generating excessive mechanical stress during tightening, potentially leading to micro-cracks in the inductor core or damage to the windings. Furthermore, under vibration and impact during equipment transportation and use, stress concentration can easily cause failure. Second, fixing structures are usually designed for specific models, lacking versatility and failing to adapt to the mounting requirements of inductors of different sizes and specifications, increasing material management and production costs. Third, traditional mounting methods often only provide unidirectional constraints, which can easily lead to loosening or displacement under complex operating conditions, resulting in poor contact or even short-circuit risks. In addition, the heat generated by the inductor during operation is not adequately considered; most mounting structures do not optimize heat dissipation paths, and heat accumulation can accelerate component aging and affect electrical performance.

[0004] Therefore, there is an urgent need for a new type of mounting bracket that can achieve adaptive clamping, multi-directional positioning, effective vibration buffering, and enhanced heat dissipation to solve these industry pain points. Utility Model Content

[0005] The purpose of this invention is to provide an inductor mounting bracket to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inductor mounting bracket, including a base plate, with a base plate fixedly connected to the upper end of the base plate by a plurality of fixing bolts, a plurality of inductors placed on the upper end of the base plate, and clamping assemblies provided at the four corners of each inductor on the upper end of the base plate, each clamping assembly including a U-shaped plate, a limiting groove provided in the middle of the upper surface of the lower end of the U-shaped plate, and positioning posts provided in the middle of the two side plates at the upper end of the U-shaped plate, with limiting springs slidably connected to the outer surface of the positioning posts, the rear end of the limiting springs located in the limiting grooves, and an L-shaped limiting frame provided at the front end of the limiting springs, with side wall positioning assemblies and top wall positioning assemblies slidably connected to the front and rear ends of the outer surface of the limiting frame respectively.

[0007] It should be noted in the solution that thermally conductive silicone grease is provided between the base plate and the substrate.

[0008] It is worth noting that a first toothed plate is provided on one side of the limiting frame, and a limiting plate is fixedly connected to the other end of the limiting frame.

[0009] Furthermore, it should be noted that each of the top wall positioning components includes a rectangular sliding plate. One end of the sliding plate has an axial first sliding groove inside. One end of the first sliding groove has a limiting structure. The other end of the limiting structure is fixedly connected to a sliding block. A connecting plate is fixedly connected to the middle of the upper end of the sliding block. A top plate is fixedly connected to the upper end of the connecting plate. The upper end of the top plate has anti-slip texture. And each of the sliding plates has an anti-slip pad fixedly connected to its lower end.

[0010] In a preferred embodiment, one end of the sliding plate is provided with a radial second sliding groove, and one side of the middle part of the second sliding groove is connected to one end of the first sliding groove.

[0011] In a preferred embodiment, each limiting structure includes a first fixed shaft, one end of which is fixedly connected to a connecting block. The outer surface of the connecting block is slidably connected to a slot provided in the second fixed shaft. The outer surfaces of both the first and second fixed shafts are slidably connected to auxiliary springs. One end of the auxiliary spring and the other end of the first fixed shaft are both fixedly connected to one side of the sliding block, and the other end of the auxiliary spring and the second fixed shaft are both fixedly connected to the other side of the first sliding groove of the sliding plate.

[0012] In a preferred embodiment, each of the sliding blocks is slidably connected to the first sliding groove, and each of the sliding blocks is provided with a second toothed plate on the other side, and the second toothed plate can be meshed with the first toothed plate.

[0013] In a preferred embodiment, the structure of the side wall positioning assembly is exactly the same as that of the top wall positioning assembly, but the lower end of the sliding plate of the side wall positioning assembly is fixedly connected with an L-shaped structure.

[0014] Compared with the prior art, the inductor mounting bracket provided by this utility model has at least the following beneficial effects:

[0015] (1) This inductor mounting bracket, through its innovative clamping component design, effectively adapts to the installation requirements of inductors of different sizes, significantly improving installation versatility and stability. The limiting spring in the clamping component works in conjunction with the L-shaped limiting bracket to provide elastic pressure in both horizontal and vertical directions, firmly securing the inductor to the substrate surface. The side wall positioning component and the top wall positioning component engage with the toothed plate through a sliding structure, achieving multi-directional synchronous adjustment and ensuring uniform force distribution at the four corners of the inductor. This dynamic clamping mechanism not only avoids stress concentration or damage to the device caused by traditional rigid fixing, but also absorbs shock through elastic elements when the equipment vibrates, greatly enhancing installation reliability and shock resistance, making it particularly suitable for electronic equipment applications in high-vibration environments.

[0016] (2) This bracket significantly improves the operating stability and lifespan of the inductor by integrating a high-efficiency heat dissipation structure. The thermally conductive silicone grease filling the space between the base plate and the substrate can quickly conduct the heat generated by the inductor during operation to the metal base plate, and then dissipate it into the surrounding environment through the large contact surface. The anti-slip pads and anti-slip textures on the bottom of the top wall positioning component ensure clamping stability while avoiding the obstruction of heat conduction by the insulating material. The metal clamping component itself also acts as an auxiliary heat sink, further optimizing thermal management efficiency. This combination of active and passive heat dissipation effectively reduces the operating temperature of the inductor, preventing performance degradation or failure due to overheating, and is particularly suitable for the thermal control requirements of high-power, high-density electronic devices.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-3 This utility model provides an inductor mounting bracket, including: a base plate 1, a base plate 2 fixedly connected to the upper end of the base plate 1 by a plurality of fixing bolts 201, a plurality of inductors 6 placed on the upper end of the base plate 2, and a clamping assembly 3 provided at the four corners of each inductor 6 on the upper end of the base plate 1, each clamping assembly 3 including a U-shaped plate 301, a limiting groove 302 provided in the middle of the upper surface of the lower end of the U-shaped plate 301, and a positioning post 303 provided in the middle of the two side plates at the upper end of the U-shaped plate 301, a limiting spring 304 slidably connected to the outer surface of the positioning post 303, the rear end of the limiting spring 304 being located in the limiting groove 302, and an L-shaped limiting frame 305 provided at the front end of the limiting spring 304, and a side wall positioning assembly 5 and a top wall positioning assembly 4 slidably connected to the front and rear ends of the outer surface of the limiting frame 305 respectively.

[0023] Further as Figure 1 As shown, it is worth noting that thermal grease 101 is provided between the base plate 1 and the substrate 2. By providing thermal grease 101 between the base plate 1 and the substrate 2, the micro-gaps of the contact surface can be effectively filled, the contact thermal resistance can be significantly reduced, and an efficient heat conduction path can be formed. This allows the heat generated by the inductor 6 during operation to be quickly conducted to the metal base plate 1 for dissipation, preventing heat accumulation and ensuring that the inductor 6 operates at a safe temperature.

[0024] Further as Figure 2 As shown, it is worth noting that a first toothed plate 3051 is provided on one side of the limiting frame 305, and a limiting plate 3052 is fixedly connected to the other end of the limiting frame 305. The first toothed plate 3051 provided on the limiting frame 305 can precisely mesh with the subsequent toothed plate structure, converting horizontal movement into vertical movement, thus achieving precision and reliability in the transmission process. The limiting plate 3052 at the other end can effectively prevent the limiting frame 305 from dislodging from the positioning post 303 under the action of the spring, ensuring the stability and safety of the entire clamping assembly 3.

[0025] Further as Figure 2As shown, it is worth noting that each of the top wall positioning components 4 includes a rectangular sliding plate 401. One end of the sliding plate 401 has an axial first sliding groove 4011 inside. One end of the first sliding groove 4011 has a limiting structure 402. The other end of the limiting structure 402 is fixedly connected to a sliding block 404. A connecting plate 405 is fixedly connected to the middle of the upper end of the sliding block 404. A top plate 406 is fixedly connected to the upper end of the connecting plate 405. The upper end of the top plate 406 has anti-slip texture 4061. Anti-slip pads 403 are fixedly connected to the lower end of each sliding plate 401. The top wall positioning component 4 moves the connecting plate 405 and the top plate 406 downward by moving the sliding block 404 in the first sliding groove 4011 of the sliding plate 401, thereby pressing the inductor 6 from above. The anti-slip texture 4061 on the upper end of the top plate 406 and the anti-slip pad 403 on the lower end of the sliding plate 401 work together to increase the friction with the surface of the inductor 6, effectively preventing it from sliding or loosening in a vibrating environment and ensuring the reliability of the fixation.

[0026] The working process of this solution is as follows: The working principle of the inductor mounting bracket is as follows: After the inductor 6 is placed on the substrate 2, the L-shaped limiting brackets 305 at the four corners are pressed, causing it to move backward against the elastic force of the limiting springs 304. The first toothed plate 3051 on the limiting bracket 305 then drives the second toothed plate 4041 that meshes with it, causing the sliding block 404 to slide within the first sliding groove 4011. The sliding block 404 pushes the top plate 406 downward through the connecting plate 405, while the L-shaped structure 501 of the side wall positioning assembly 5 moves inward, thereby pressing the inductor 6 from the top and side simultaneously. The auxiliary spring 4024 in the limiting structure 402 provides buffering to ensure uniform and stable clamping force. Throughout the process, the thermal grease 101 conducts the heat generated by the inductor 6 to the base plate 1 for heat dissipation.

[0027] As can be seen from the above working process: by setting thermally conductive silicone grease 101 between the base plate 1 and the substrate 2, the microscopic gaps on the contact surface can be effectively filled, the contact thermal resistance can be significantly reduced, and an efficient heat conduction path can be formed. This allows the heat generated by the inductor 6 during operation to be quickly conducted to the metal base plate 1 for dissipation, preventing heat accumulation and ensuring that the inductor 6 operates at a safe temperature. The first toothed plate 3051 on the limiting frame 305 can precisely mesh with the subsequent toothed plate structure, converting horizontal movement into vertical movement, thus achieving precision and reliability in the transmission process. The limiting plate 3052 at the other end can effectively prevent the limiting frame 305 from dislodging from the positioning post 303 under the action of the spring, ensuring the stability and safety of the entire clamping assembly 3. The top wall positioning assembly 4 moves the connecting plate 405 and the top plate 406 downward by moving the sliding block 404 in the first sliding groove 4011 of the sliding plate 401, thereby pressing the inductor 6 from above. The anti-slip texture 4061 on the upper end of the top plate 406 and the anti-slip pad 403 on the lower end of the sliding plate 401 work together to increase the friction with the surface of the inductor 6, effectively preventing it from sliding or loosening in a vibrating environment and ensuring the reliability of the fixation.

[0028] Further as Figure 2 As shown, it is worth noting that one end of the sliding plate 401 is provided with a radial second sliding groove 4012, and one side of the middle part of the second sliding groove 4012 is connected to one end of the first sliding groove 4011. The radial second sliding groove 4012 provided at one end of the sliding plate 401 and connected to the first sliding groove 4011 provides the necessary space for the installation and movement of the limiting structure 402, allowing it to be adjusted in angle or displaced within a certain range, thus enhancing the flexibility and adaptability of the mechanism design.

[0029] Further as Figure 2 As shown, it is worth noting that each limiting structure 402 includes a first fixed shaft 4021. One end of the first fixed shaft 4021 is fixedly connected to a connecting block 4022. The outer surface of the connecting block 4022 is slidably connected to a slot provided in the second fixed shaft 4023. The outer surfaces of the first fixed shaft 4021 and the second fixed shaft 4023 are slidably connected to auxiliary springs 4024. One end of the auxiliary spring 4024 and the other end of the first fixed shaft 4021 are fixedly connected to one side of the sliding block 404. The other end of the auxiliary spring 4024 and the second fixed shaft 4023 are fixedly connected to the other side of the first sliding groove 4011 of the sliding plate 401. The limiting structure 402 forms an elastic connection mechanism through the cooperation of the first fixed shaft 4021, the second fixed shaft 4023 and the auxiliary spring 4024. This structure not only provides a stable sliding guide for the slider 404, but also the auxiliary spring 4024 can play a role in buffering and adaptive adjustment, so that the pressure applied by the top plate 406 is both sufficient and gentle, avoiding damage to the inductor 6 due to excessive pressure.

[0030] Further as Figure 2 As shown, it is worth noting that each sliding block 404 is slidably connected to the first sliding groove 4011, and each sliding block 404 has a second toothed plate 4041 on its other side. The second toothed plates 4041 can mesh with the first toothed plates 3051. The second toothed plates 4041 on the other side of the sliding block 404 mesh with the first toothed plates 3051 on the limiting frame 305. This is an efficient and reliable power transmission method. It accurately converts the horizontal linear motion of the limiting frame 305 into the vertical linear motion of the sliding block 404. The transmission ratio is fixed, avoiding slippage and ensuring the synchronization and accuracy of the top wall positioning assembly 4's movements.

[0031] Further as Figure 3 As shown, it is worth noting that the structure of the side wall positioning component 5 is exactly the same as that of the top wall positioning component 4. However, the lower end of the sliding plate 401 of the side wall positioning component 5 is fixedly connected to an L-shaped structure 501. The side wall positioning component 5 has the same transmission and buffering structure as the top wall positioning component 4, ensuring consistency in operating feel and efficiency. Its unique feature is the L-shaped structure 501 fixedly connected to the lower end of the sliding plate 401. This structure can limit and clamp the inductor 6 from the side, working in conjunction with the top wall positioning component 4 to achieve omnidirectional fixation of the inductor 6 in both vertical and horizontal directions, greatly improving stability.

[0032] In summary: A radial second sliding groove 4012 is provided at one end of the sliding plate 401, and it is connected to the first sliding groove 4011. This structure provides the necessary space for the installation and movement of the limiting structure 402, allowing it to be adjusted in angle or displaced within a certain range, thus enhancing the flexibility and adaptability of the mechanism design. The limiting structure 402 forms an elastic connection mechanism through the cooperation of the first fixed shaft 4021, the second fixed shaft 4023, and the auxiliary spring 4024. This structure not only provides a stable sliding guide for the sliding block 404, but the auxiliary spring 4024 also plays a role in buffering and adaptive adjustment, ensuring that the pressure applied by the top plate 406 is both sufficient and gentle, avoiding damage to the inductor 6 due to excessive pressure. The second toothed plate 4041 provided on the other side of the sliding block 404 meshes with the first toothed plate 3051 on the limiting frame 305, which is an efficient and reliable power transmission method. It precisely converts the horizontal linear motion of the limiting bracket 305 into the vertical linear motion of the sliding block 404. With a fixed transmission ratio, slippage is avoided, ensuring the synchronization and accuracy of the top wall positioning component 4's movements. The side wall positioning component 5 has the exact same transmission and buffering structure as the top wall positioning component 4, guaranteeing consistency in operating feel and performance. Its unique feature is the L-shaped structure 501 fixedly connected to the lower end of the sliding plate 401. This structure can limit and clamp the inductor 6 from the side, working in conjunction with the top wall positioning component 4 to achieve omnidirectional fixation of the inductor 6 in both vertical and horizontal directions, greatly improving stability.
