Description

Technical Field

[0001] This utility model relates to the field of energy storage capacitor technology, and in particular to an energy harvesting capacitor. Background Technology

[0002] An energy-harvesting capacitor is a type of capacitor that can collect and store energy from the external environment. Its application prospects include smart devices, wearable devices, environmental monitoring, healthcare, and wireless sensor networks. An energy-harvesting capacitor is a device that uses external environmental energy sources (such as light, heat, motion, or electromagnetic fields) to collect energy and store it as electrical energy in the capacitor. This technology allows devices to obtain energy from a continuous supply of low-level energy sources and provide high-energy output when needed; it is also called an energy storage capacitor.

[0003] In the prior art, energy harvesting capacitors, especially high-energy-density capacitors, often have a large size and weight due to their design characteristics and technical requirements. Most of these capacitors are cylindrical in shape, which brings a series of challenges when installing them into matching circuits and circuit boards. Because their surfaces are smooth and lack force-bearing points, existing clamps are difficult to hold and adapt to these capacitors, as they are prone to falling off during the clamping process. This not only increases the difficulty of installation but also reduces work efficiency. To ensure stability during clamping, the clamping force of the clamping components needs to be greatly increased. However, this increased clamping force can cause scratches on the capacitor surface, resulting in scratches or even damage to the outer layer of the capacitor, causing internal materials to leak out. This situation not only affects the performance and lifespan of the capacitor but also damages the entire circuit system. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy harvesting capacitor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy harvesting capacitor, comprising a capacitor body, a clamping member at the top of the capacitor body, a parallel horizontal clamping groove on one side of the clamping member, the inner edge of the parallel horizontal clamping groove being rounded, a horizontal inner triangular stop fixed to the inner wall of the parallel horizontal clamping groove, and a vertical clamping groove at the top of the middle part of the clamping member.

[0006] Preferably, a vertically placed triangular ring is fixed to the bottom circumference of the capacitor body. In the prior art, when the capacitor body is installed perpendicular to the ground, due to the large volume and weight of this type of capacitor, its center of gravity is high. During the production process, especially when subjected to vibration or bumps during transportation, this high center of gravity design makes the capacitor more prone to tipping and tilting. This not only leads to the failure of the connection between the product and the circuit board, but also causes a short circuit, thus making the product unusable. Once such a failure occurs, not only is it necessary to repair or replace the product, but it also greatly increases the subsequent maintenance costs. To address this problem, this utility model adopts the installation of a vertically placed triangular ring. The ring design ensures that after the capacitor body is installed, the vertical triangular ring makes tight contact with the installed circuit board. This design not only provides additional stability but also ensures that the capacitor remains in place despite vibrations during production or bumps during transportation. In this way, the connection between the capacitor and the circuit board is effectively protected, preventing short circuits and potential damage caused by instability. This design significantly improves the reliability and durability of the entire circuit system, reduces the need and cost of subsequent maintenance, and achieves the effect of improving equipment stability and reducing equipment maintenance costs.

[0007] Preferably, a buffer ring is fixed to the bottom of the capacitor body. In the prior art, when workers install the energy harvesting type high-energy-density capacitor body, the leads of this type of capacitor are usually connected to the circuit board by threaded rods. This design aims to ensure the stability of the connection to the greatest extent. However, in actual operation, when workers gradually screw the capacitor into the circuit board, one end of the capacitor will contact the circuit board first. As the capacitor is screwed in further, it begins to rotate and rub against the circuit board. This continuous friction causes severe wear on the surface of the circuit board, which in turn affects the overall service life of the equipment. To address this problem, this utility model uses the installation of a buffer ring to solve the problem. When one end of the capacitor first contacts the circuit board, the buffer ring provides cushioning, so that the pressure on the circuit board is gradually dispersed as the area of ​​the buffer ring increases, reducing the pressure per unit area. At the same time, the material of the buffer ring effectively prevents friction on the circuit board. After the buffer ring is compressed, its elastic deformation reaction force is applied to the capacitor body, which effectively prevents the threaded connection between the capacitor body and the circuit board from slipping, thereby improving the service life of the equipment.

[0008] Preferably, the capacitor body is covered with a polymer insulating layer, and the polymer insulating layer has pre-cut grooves on its peripheral surface. This provides insulation to the outer surface of the capacitor body, increases its overall toughness, and effectively prevents scratches on the surface. The polymer insulating layer also facilitates the printing of usage instructions and positive / negative markings, improving the user experience. Furthermore, the pre-cut grooves make it easy for workers to remove the polymer insulating layer, facilitating the separation of used products and further enhancing the user experience.

[0009] Preferably, the vertical clamping groove has a linear array of vertical anti-slip grooves on one side of its inner wall, which increases friction, makes it easier for workers or equipment to clamp, and improves work efficiency.

[0010] Preferably, the capacitor body has a top recessed groove, and the inner wall of the top recessed groove is fixed to the bottom of the clamping component, which reduces the installation height of the clamping component, reduces the space occupied, improves the space utilization rate, and achieves the effect of reducing production costs.

[0011] Preferably, the bottom of the capacitor body is provided with a bottom arc groove, which realizes the deformation space during screwing and achieves the effect of improving product stability. Beneficial effects

[0012] In existing technologies, energy harvesting capacitors, especially high-energy-density capacitors, often have a large size and weight due to their design characteristics and technical requirements. Most of these capacitors are cylindrical, which presents a series of challenges when installing them into matching circuits and circuit boards. Because their surfaces are smooth and lack support points, existing clamps are difficult to hold and adapt to these capacitors, as they are prone to detachment during clamping. This not only increases the difficulty of installation but also reduces work efficiency. To ensure stability during clamping, the clamping force needs to be greatly increased. However, this increased force can cause scratches on the capacitor surface, even damaging the outer layer and causing internal materials to leak out. This not only affects the capacitor's performance and lifespan but also damages the entire circuit system. To address these problems, this invention uses a clamping device to solve the issue, allowing operators to use a clamping device to grip the capacitor body at the start of production. Choosing the appropriate clamping method is crucial for different clamp designs. When using a clamp parallel to the ground, the operator inserts the clamping end through or across the parallel horizontal clamping groove of the clamped component. Once the clamping end enters the parallel horizontal clamping groove, the inner triangular stop provides necessary restraint and increases friction by increasing the contact area. This effectively prevents the clamping end from easily leaving the parallel horizontal clamping groove. This design makes it easier for the operator to install capacitors into holes parallel to the ground. On the other hand, when using a clamp perpendicular to the ground, the operator inserts the clamping end into the vertical clamping groove of the clamped component and presses it towards the center. Since the lower end of the vertical clamping groove is smaller than the upper end, this design allows the vertical clamping groove to better fit the clamping end, thereby increasing the clamping and fixing effect. This design not only improves work efficiency but also ensures the accuracy and stability of capacitor installation, improves user experience, and expands the applicability of the product.

[0013] In existing technologies, when the capacitor body is installed vertically to the ground, due to its large size and weight, its center of gravity is high. During production, especially when subjected to vibration or bumps during transportation, this high center of gravity makes the capacitor more prone to tipping and tilting. This not only leads to connection failure between the product and the circuit board but also causes short circuits, rendering the product unusable. Such failures require repair or replacement, significantly increasing subsequent maintenance costs. To address this issue, this invention uses a vertically placed triangular ring. After the capacitor body is installed, the ring is in close contact with the circuit board. This design provides additional stability and ensures the capacitor remains in place despite vibrations during production or bumps during transportation. This effectively protects the connection between the capacitor and the circuit board, preventing short circuits and potential damage caused by instability. This design significantly improves the reliability and durability of the entire circuit system, reduces subsequent maintenance needs and costs, and ultimately enhances equipment stability and reduces maintenance expenses.

[0014] In existing technologies, when workers install high-energy-density energy-harvesting capacitors, the capacitor leads are typically connected to the circuit board via threaded rods. This design aims to maximize connection stability. However, in actual operation, as workers gradually screw the capacitor into the circuit board, one end of the capacitor contacts the board first. As the capacitor is further screwed in, it begins to rotate and rub against the circuit board. This continuous friction causes severe wear on the circuit board surface, thus affecting the overall lifespan of the equipment. To address this problem, this invention uses a buffer ring pad. When one end of the capacitor first contacts the circuit board, the buffer ring pad provides cushioning, gradually dispersing the pressure on the circuit board as the area of ​​the buffer ring pad increases, reducing the pressure per unit area. Simultaneously, the buffer ring pad material effectively prevents friction on the circuit board. Furthermore, the reaction force of the elastic deformation of the buffer ring pad after compression is applied to the capacitor body, effectively preventing slippage of the threaded connection between the capacitor body and the circuit board, thereby improving the lifespan of the equipment.

Detailed Implementation

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation

[0023] Reference Figure 1-4An energy harvesting capacitor includes a capacitor body 1, a clamping member 2 on the top of the capacitor body 1, a parallel horizontal clamping groove 201 on one side of the clamping member 2, the inner edge of the parallel horizontal clamping groove 201 is rounded, a horizontal inner triangular stop 203 is fixed on the inner wall of the parallel horizontal clamping groove 201, and a vertical clamping groove 202 is opened at the top of the middle part of the clamping member 2. A vertical triangular ring 3 is fixed to the bottom circumference of the capacitor body 1. When the capacitor body 1 is installed perpendicular to the ground, due to the large size and weight of this type of capacitor, its center of gravity is high. During the production process, especially when subjected to vibration or bumps during transportation, this high center of gravity makes the capacitor more prone to tipping and tilting. This not only leads to the failure of the connection between the product and the circuit board, but also causes short circuits, making the product unusable. Once such a failure occurs, not only is it necessary to repair or replace the product, but it also greatly increases the subsequent maintenance costs. The method of installing the vertical triangular ring 3 solves this problem. After the staff completes the installation of the capacitor body 1, the vertical triangular ring 3 will be in close contact with the installed circuit board. This design not only provides additional stability, but also ensures that the capacitor can maintain its position without tilting when it is subjected to vibration during production or bumps during transportation. In this way, the connection between the capacitor and the circuit board is effectively guaranteed, thereby preventing short circuits and potential damage caused by instability. This design significantly improves the reliability and durability of the entire circuit system, reduces the need and cost of subsequent maintenance, and achieves the effect of improving equipment stability and reducing equipment maintenance costs.

[0024] A buffer ring 301 is fixed to the bottom of the capacitor body 1. When the operator installs the energy-harvesting high-energy-density capacitor body 1, the leads of this type of capacitor are usually connected to the circuit board by threaded rods. This design aims to ensure the stability of the connection to the greatest extent. However, in actual operation, when the operator gradually screws the capacitor into the circuit board, one end of the capacitor will contact the circuit board first. As the capacitor is screwed in further, it begins to rotate and rub against the circuit board. This continuous friction causes severe wear on the surface of the circuit board, which in turn affects the overall service life of the equipment. The installation of the buffer ring 301 solves this problem. When one end of the capacitor first contacts the circuit board, the buffer ring 301 provides buffering, so that the pressure on the circuit board is gradually dispersed as the area of ​​the buffer ring 301 increases, reducing the pressure per unit area. At the same time, the material of the buffer ring 301 effectively prevents friction on the circuit board. After the buffer ring 301 is compressed, its elastic deformation reaction force is applied to the capacitor body 1, which effectively prevents the threaded connection between the capacitor body 1 and the circuit board from slipping, thereby improving the service life of the equipment. The capacitor body 1 is covered with a polymer insulating layer 4. Pre-cut grooves 401 are formed on the periphery of the polymer insulating layer 4, providing insulation to the outer surface. Simultaneously, the polymer insulating layer 4 increases the overall toughness of the capacitor body 1 and effectively prevents scratches on its surface. The polymer insulating layer 4 also facilitates the printing of usage instructions and positive / negative markings, improving user experience. The pre-cut grooves 401 facilitate the removal of the polymer insulating layer 4, making it easier to identify and separate used products, further enhancing user experience. Vertical anti-slip grooves 204 are linearly arrayed on one side of the inner wall of the vertical clamping groove 202, increasing friction and facilitating clamping by workers or equipment, thus improving work efficiency. A top recess 205 is formed on the top of the capacitor body 1. The inner wall of the top recess 205 is fixed to the bottom of the clamping component 2, reducing the installation height of the clamping component 2, minimizing space occupation, improving space utilization, and ultimately reducing production costs. The bottom of the capacitor body 1 has a bottom arc groove 302, which allows for the deformation space during screwing, thereby improving the stability of the product.

[0025] The working principle of this utility model is as follows: When production begins, the operator needs to use a clamping device to clamp the capacitor body 1. Selecting the appropriate clamping method based on different clamp designs is crucial. When using a clamp parallel to the ground, the operator inserts the clamping end through or across the parallel horizontal clamping groove 201 of the clamped part 2. Once the clamping end enters the parallel horizontal clamping groove 201, the inner triangular stop 203 provides necessary restraint and increases friction by increasing the contact area. This effectively prevents the clamping end from easily leaving the parallel horizontal clamping groove 201. This design allows the operator to more easily install the capacitor into the hole parallel to the ground. On the other hand, when using a clamp perpendicular to the ground, the operator inserts the clamping end into the vertical clamping groove 202 of the clamped part 2 and presses it towards the center for clamping. Due to the vertical... The lower end of the inner wall of the vertical clamping groove 202 is smaller than the upper end. This design allows the vertical clamping groove 202 to fit the clamp end better, thereby increasing the clamping and fixing effect during clamping. This design not only improves work efficiency but also ensures the accuracy and stability of capacitor installation. After the operator completes the installation of the capacitor body 1, the vertical triangular ring 3 will be in close contact with the installed circuit board. This design not only provides additional stability but also ensures that the capacitor can maintain its position without tilting when it encounters vibrations during production or bumps during transportation. In this way, the connection between the capacitor and the circuit board is effectively guaranteed, thereby preventing short circuits and potential damage caused by instability. This design significantly improves the reliability and durability of the entire circuit system and reduces the need and cost of subsequent maintenance.
