Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically to an inductor using a novel structural base plate. Background Technology

[0002] With the rapid development of electronic devices towards miniaturization and integration, inductors, as an indispensable electronic component in circuits, have a direct impact on the performance and production efficiency of the entire electronic device due to the stability and ease of their installation.

[0003] Traditional inductors are often installed manually, with the inductor connected to the circuit board via soldering. However, this method has several drawbacks: First, manual positioning has low accuracy, leading to inductor misalignment and other issues that can cause relative positional deviations between the inductor and surrounding components, affecting electromagnetic compatibility and overall circuit performance, and potentially even causing circuit malfunctions due to improper installation. Second, soldering or screw fixing is cumbersome and time-consuming, severely hindering production efficiency. Disassembly is equally complex when the inductor needs repair, replacement, or adjustment. Disassembling soldered inductors requires high-temperature melting of the solder, which is not only inconvenient but can also damage the circuit board and surrounding components. While some inductors have simple limiting structures, their limiting effect is poor, and there is a lack of quick-fixing and disassembly components to work with these structures, failing to meet the demands of modern electronics manufacturing for efficient assembly and convenient maintenance. Therefore, we need an inductor with a novel base plate structure. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an inductor using a novel structural base plate, comprising:

[0023] The inductor motherboard 1, the inductor body 2, and the positioning and mounting component 3 are provided. The inductor body 2 is mounted on the top of the inductor motherboard 1 via the positioning and mounting component 3. The positioning and mounting component 3 is used to facilitate the installation and removal of the inductor body 2 from the inductor motherboard 1.

[0024] The positioning and mounting assembly 3 includes a base 31, an arc groove 32, side wings 33, and a limiting member 34. The two bases 31 are fixed to the top of the inductor main board 1. An arc groove 32 is provided on the top for placing the inductor body 2. Side wings 33 are provided on both sides of the arc groove 32 to limit the horizontal movement of the inductor body 2. The limiting member 34 is installed inside the inductor main board 1 to fit the inductor body 2 and to fix the inductor body 2 vertically.

[0025] Specifically, the positioning and mounting component 3 allows the inductor body 2 to be placed within the two bases 31 on top of the inductor motherboard 1 for horizontal fixation. The limiting component 34 further secures the inductor body 2 vertically, enabling rapid installation. Horizontally, the arc-shaped grooves 32 of the two bases 31 and the side wings 33 form a precise limiting space, ensuring a stable fit and preventing horizontal displacement due to vibration or shift. This ensures the relative positional accuracy between the inductor body 2 and the motherboard, improving circuit stability. Vertically, the limiting component 34 provides efficient fixation. The pressure cover 341, along with the inclined structure of the insert plate 342, the clip plate 343, and the slot 344, allows for easy locking and fixing simply by inserting the insert plate 342 into the motherboard.

[0026] The limiting component 34 includes a pressure cover 341, an insert plate 342, a card plate 343, and a card slot 344. The pressure cover 341 is located inside the inductor body 2. Insert plates 342 are fixedly installed on both sides of the bottom. Card plates 343 are fixedly installed on the opposite side of the two insert plates 342. A card slot 344 for inserting the card plate 343 is opened in the inductor main board 1.

[0027] Furthermore, the pressure cover 341 is located inside the inductor body 2, facilitating its insertion. The insertion plates 342 on both sides of the bottom are welded to the pressure cover 341, and the weld joints are coated with insulating sealant to enhance connection strength while ensuring insulation. The retaining plate 343 on the opposite side of the two insertion plates 342 is integrally formed with the insertion plates 342. The inclined angle of the retaining plate 343 is set at 30°-45°. The slot 344 in the inductor main board 1 is clearance-fitted with the insertion plate 342, with a clearance value of 0.05-0.1mm, ensuring smooth insertion of the insertion plate 342. This structure, through the pressure cover 341, insertion plate 342, and retaining plate... The coordinated operation of 343 and slot 344 enables rapid vertical fixation of the inductor body 2. The use of an integrally molded card plate 343 and insert plate 342 reduces assembly steps, improves structural stability, and solves the problem of easy loosening of parts in traditional fixing methods. The use of insulating sealant avoids leakage at the welding point, improving the safety of the inductor. Insert plate 342 is made of spring steel plate with a thickness of 0.8-1.2mm. Card plate 343 is integrally stamped with insert plate 342. Slot 344 is machined by a milling machine, and its inner wall roughness is controlled below Ra1.6 to ensure smooth insertion of insert plate 342.

[0028] The insert plate 342 is a metal plate, the card plate 343 is a beveled type, and the top side of the card slot 344 is provided with a beveled part 4 that works with the card plate 343.

[0029] It is worth noting that the insert plate 342 is made of 65Mn spring steel plate. This material has good elasticity and toughness, and can quickly recover after deformation, ensuring that the clamping plate 343 can be smoothly inserted into the clamping slot 344 and remain stable. The clamping plate 343 is designed with a beveled surface, the length of which is 3-5mm. The beveled part 4 on the top side of the clamping slot 344 has the same inclination angle as the beveled surface of the clamping plate 343, and the surface of the beveled part 4 is polished to reduce the friction when the clamping plate 343 contacts the beveled part 4. The selection of 65Mn spring steel plate allows the insert plate 342 to produce appropriate deformation when compressed, ensuring that the clamping plate 343 can pass smoothly through the beveled part 4. When the clamping plate 343 is fully inserted into the clamping slot 344, the insert plate 342 recovers, and the clamping plate 343 can fit tightly against the bottom of the clamping slot 344, improving the reliability of the fixation and solving the problems of easy damage and insecure fixation of traditional buckles. The insert plate 342 can also be made of 7075 aluminum alloy plate, which has high strength and light weight, and is suitable for scenarios with strict weight requirements.

[0030] The bottom of the pressure cap 341 is provided with a groove 5 that fits into the inner wall of the inductor body 2, and an adhesive layer seat 6 is fixedly installed in the groove 5;

[0031] It should be noted that the radius of the arc-shaped groove 32 at the bottom of the pressure cap 341 is 0.1-0.2mm larger than the radius of the inner wall of the inductor body 2, ensuring that the arc-shaped groove 32 fits well with the inner wall of the inductor body 2. The adhesive layer seat 6 inside the arc-shaped groove 32 is made of silicone rubber with a Shore hardness of 50-60. The adhesive layer seat 6 is bonded to the groove 5 with epoxy resin adhesive. The thickness of the adhesive layer seat 6 is 1-2mm, and it can generate a compression of 0.3-0.5mm when the pressure cap 341 is pressed down for installation. The silicone rubber adhesive layer seat 6 has good elasticity. In terms of buffering performance, when the pressure cap 341 is installed, the adhesive layer seat 6 is compressed and generates an upward elastic force, which makes the top of the card plate 343 fit tightly against the bottom of the inductor main board 1, enhancing the limiting effect. At the same time, it can absorb the vibration generated during the operation of the inductor, reduce the wear between the inductor body 2 and the pressure cap 341, and solve the problem of easy damage to parts caused by hard contact. Multiple micro bumps with a diameter of 0.5mm can be set on the surface of the adhesive layer seat 6 to increase the friction with the inner wall of the inductor body 2, further improving the cooperative stability of the pressure cap 341 and the inductor body 2.

[0032] It also includes a fixing member 7 for the abutting plug 342. The fixing member 7 includes a circular groove 71, a column 72 and an abutting plate 73. The circular groove 71 is opened at the bottom of the inductor main board 1, and the column 72 is rotatably installed inside. The abutting plate 73 is fixedly installed on the surface of the column 72. The abutting plate 73 is located between the two plugs 342 and is used to limit the plugs 342.

[0033] Specifically, the diameter of the circular groove 71 of the fixing component 7 is 0.2-0.3mm larger than the diameter of the column 72. The column 72 and the contact plate 73 are integrally injection molded, and the material is ABS engineering plastic, which has good strength and toughness. The contact plate 73 can be smoothly inserted between the two insert plates 342 and effectively limit the position of the insert plates 342. The cooperation between the fixing component 7 and the insert plates 342 further restricts the shaking of the insert plates 342, avoids the displacement of the insert plates 342 due to vibration after long-term use, and improves the stability of the overall inductor structure. The use of ABS engineering plastic reduces the weight of the fixing component 7 and has good corrosion resistance, solving the problem of easy rusting of metal fixing components 7.

[0034] A rubber sleeve 8 is fixedly installed on the surface of the column 72, and the outer surface of the rubber sleeve 8 is tightly fitted to the inner wall of the circular groove 71.

[0035] The rubber sleeve 8 on the surface of the column 72 is made of nitrile rubber with a thickness of 0.3-0.5mm. The rubber sleeve 8 is fitted onto the column 72 with an interference fit of 0.05-0.1mm. The outer surface of the rubber sleeve 8 may have evenly distributed annular protrusions with a height of 0.1-0.2mm, which increases the friction with the inner wall of the circular groove 71. Nitrile rubber has good wear resistance and elasticity. The tight fit between the rubber sleeve 8 and the inner wall of the circular groove 71 provides suitable friction, which can effectively prevent the contact plate 73 from rotating on its own, ensuring the durability of the limiting of the insertion plate 342 and solving the problem of easy loosening of the traditional fastener 7.

[0036] The inductor main board 1 has four internally threaded mounting sleeves 9;

[0037] The mounting sleeve 9 is made of 45# steel with an internal thread of M3-M5 fine thread with self-locking function and a thread accuracy of 6H. The mounting sleeve 9 is connected to the inductor main board 1 by interference fit with an interference amount of 0.01-0.03mm. Both ends of the mounting sleeve 9 are flush with the surface of the inductor main board 1. The 45# steel mounting sleeve 9 has high strength, which can ensure a reliable connection between the inductor main board 1 and the external structure. The fine thread design increases the tightness of the connection. The rectangular distribution of the mounting sleeves 9 makes the inductor force uniform, improves the stability of the installation, and solves the problems of inductor tilting and unstable installation in traditional installation methods.

[0038] This device places the inductor body 2 in the arc-shaped grooves 32 on the top of the two bases 31. The arc-shaped grooves 32 are adapted to the surface of the inductor body 2. The side wings 33 on both sides of the arc-shaped grooves 32 provide a good limiting effect for the inductor body 2. The pressure cover 341 is placed in the inductor body 2. As the pressure cover 341 moves down, the two insert plates 342 at the bottom of the pressure cover 341 are respectively inserted into the two slots 344 in the main inductor 1. The top side of the slot 344 has a beveled part 4, which works with the slot plate 343 when the bottom of the insert plate 342 is tilted. The slot plate 343 contacts the beveled part and presses the insert plate 342 until the entire slot plate 343 is located at the bottom of the main inductor 1. The insert plate 342 is a metal plate that can be restored after deformation. The pressure cover 341 The bottom has a groove 5 that fits into the inner wall of the inductor body 2, and the groove 5 has an adhesive layer seat 6. When the pressure cover 341 is pressed down, the adhesive layer seat 6 is compressed. When the card plate 343 is completely located at the bottom of the inductor main board 1, the adhesive layer seat 6 pushes the pressure cover 341 upward, so that the top of the card plate 343 fits against the bottom of the inductor main board 1, which has a limiting effect. The contact plate 73 is rotated so that the two ends of the contact plate 73 are respectively located on one side of the two insert plates 342, limiting the insert plates 342. The rotation of the contact plate 73 will drive the column 72 to rotate in the circular groove 71. An adhesive layer sleeve 8 is fixedly installed on the surface of the column 72. The adhesive layer sleeve 8 is made of rubber and is located in the circular groove 71. When the column 72 rotates, it provides friction and prevents the contact plate 73 from rotating on its own.
