Description

Technical Field

[0001] This utility model relates to protective covers for electronic devices, specifically, to a protective cover for a supercapacitor with protective functions. Background Technology

[0002] In end products, supercapacitors need to be installed. Existing supercapacitor protective sleeves are merely a single layer of plastic film, which is prone to aging and lacks a cushioning structure. Under external force, the capacitor may deform, and the seal may fail, potentially leading to electrolyte leakage. The electrolyte is conductive and corrosive; leakage can cause short circuits and corrode surrounding components.

[0003] Chinese Patent Publication No. CN206179688U, Publication Date: May 17, 2017, discloses a 48V supercapacitor module, including a heat dissipation insulating plate, side plates, a top cover, and a bottom plate. A supercapacitor unit is fixed inside a closed space formed by the top cover, two heat dissipation insulating plates, two side plates, and the bottom plate. There are eighteen supercapacitor units. A connecting component connects two adjacent supercapacitor units in series. An insulating and thermally conductive protective sleeve is fitted onto the surface of each supercapacitor unit. However, this patent only has one layer of insulating and thermally conductive protective sleeve for the supercapacitor, lacking a buffer structure and thus failing to provide protection for the supercapacitor. Utility Model Content

[0004] This invention provides a protective sleeve for supercapacitors with protective functions. By setting baffles, multiple protections are achieved for the supercapacitor, preventing electrolyte leakage. The tail end is level with the front end, extending its service life.

[0005] A further objective of this invention is to make the installation of supercapacitors convenient and stable by setting a flange.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a supercapacitor protective sleeve with protective function, comprising a protective sleeve body, the protective sleeve body being a shell with a first opening on the upper surface, a baffle at one end, and a second opening at the other end; a welding seat is provided at the bottom of the second opening, the welding seat is provided with a plurality of slots, a plurality of balance columns are provided on the lower surface of the protective sleeve body on the side of the baffle, and flanges are provided on both sides of the protective sleeve body.

[0007] Preferably, the protective sleeve body is a rectangular shell with a U-shaped longitudinal section. The outer structure is made of highly flame-retardant and corrosion-resistant PP material, with a first opening cut out on the surface to facilitate heat dissipation. The rectangular shell structure is simple and easy to manufacture, while the U-shaped longitudinal section can better fit the shape of the supercapacitor, providing more stable enclosure and protection. The highly flame-retardant and corrosion-resistant PP material can effectively prevent the protective sleeve from being damaged by high temperatures or corrosive substances during use, extending its service life. The design of the first opening not only facilitates heat dissipation for the supercapacitor but also reduces the weight of the protective sleeve to a certain extent, lowering material costs.

[0008] Preferably, solder pads are inserted into the slots, and the protective sleeve body is soldered to the PCB board via a soldering base. The slots are used for soldering holes, directly soldered onto the PCB board along with existing supercapacitors; the slots are rectangular and located on both sides of the soldering base. This design of the slots and soldering base ensures a stable connection between the protective sleeve body and the PCB board, preventing loosening or detachment due to vibration or external force during use. This connection method is compatible with existing supercapacitor mounting methods, requiring no large-scale modifications to existing equipment, facilitating widespread application. The rectangular slots allow for precise positioning of the solder pads, improving soldering accuracy and reliability, reducing soldering defects, and increasing production efficiency.

[0009] Preferably, several balance columns are symmetrically and evenly arranged along the axis of symmetry of the protective sleeve body, with the flanges pointing vertically upwards and possessing elasticity. The symmetrical and even arrangement of the balance columns ensures that the protective sleeve body maintains good balance during installation and use, avoiding instability caused by a shift in the center of gravity. This helps improve the fitting accuracy between the protective sleeve and the supercapacitor and PCB board, reducing displacement or shaking caused by vibration or external forces, thereby enhancing the stability and reliability of the entire device.

[0010] Preferably, the lower surfaces of the balance pillars and the soldering base are on the same horizontal plane. The flange connects to the curved surface of the protective sleeve body. The balance pillars are small rectangular blocks, respectively located on both sides of the lower surface of the protective sleeve body. The fact that the lower surfaces of the balance pillars and the soldering base are on the same horizontal plane ensures that the bottom of the protective sleeve body is flat during placement or installation, further improving its stability. The small rectangular balance pillar structure is simple, easy to manufacture, and its symmetrical arrangement on both sides better distributes the force, preventing excessive localized stress from damaging the protective sleeve body or affecting its connection with the PCB board.

[0011] Preferably, the upper surface of the soldering base is flush with the inner wall of the bottom of the protective sleeve body. The soldering base is rectangular. The flushness of the upper surface of the soldering base with the inner wall of the bottom of the protective sleeve body makes the internal space of the protective sleeve body more regular, which is beneficial for the installation and fixation of the supercapacitor and avoids squeezing or damage to the supercapacitor due to the protruding soldering base. The rectangular soldering base has a simple structure, is easy to process, and can provide sufficient soldering area to ensure a firm connection between the protective sleeve body and the PCB board.

[0012] Preferably, the baffle includes a side plate and a top cover plate, and the baffle is located at the tail end of the supercapacitor. The baffle composed of the side plate and the top cover plate can provide comprehensive protection for the tail end of the supercapacitor, preventing damage from external impacts, pressure, or corrosion during use. At the same time, the presence of the baffle can also prevent electrolyte leakage from the tail end to a certain extent, further improving the protective performance of the protective sleeve.

[0013] Preferably, the welding base is located at the front end of the supercapacitor, and the front and rear ends of the supercapacitor are at the same horizontal height. The balancing column ensures that the rear end of the supercapacitor is at the same horizontal height as the front end. The welding base being located at the front end, and the front and rear ends being at the same horizontal height, ensures that the supercapacitor remains horizontal after installation, which is beneficial to the stable operation of its internal structure and reduces electrical performance problems that may be caused by tilting. The balancing column further ensures that the rear end and front end are at the same horizontal height, improving the stability and reliability of the entire device and avoiding stress concentration or installation deviations caused by height differences.

[0014] Preferably, the side plate covers the outer surface of the supercapacitor's tail end. This effectively prevents external dust, impurities, moisture, etc., from entering the supercapacitor's interior, providing a good seal and protection for the supercapacitor's tail end, extending its service life, and improving its reliability in harsh environments.

[0015] Preferably, the top cover is a U-shaped plate, positioned above the tail end of the supercapacitor. The U-shaped top cover better conforms to the shape of the supercapacitor's tail end, providing more comprehensive top protection and preventing direct impact or pressure from external objects. Simultaneously, the U-shaped structure can guide the flow of electrolyte leakage to some extent, preventing electrolyte accumulation above the tail end and further improving the protective performance of the cover.

[0016] The beneficial effects of this utility model are: 1. It enables rapid installation during mass production; 2. It prevents electrolyte from splashing everywhere when the terminal is working, thus protecting the circuit board; 3. The first opening on the surface facilitates heat dissipation of the supercapacitor. Attached Figure Description

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

[0022] When the end product is in operation, existing supercapacitors may leak electrolyte due to factors such as overcharging, overvoltage, high temperature, cyclic charging and discharging, aging of sealing materials, and slight deformation of the casing. The electrolyte is conductive and corrosive; leakage can lead to short circuits, corrosion of surrounding components, and ultimately, product failure. The protective sleeves of existing supercapacitors are insufficient to prevent electrolyte leakage. The supercapacitor's tail section has a 1.4mm balance column, and the solder joints are subject to significant stress, posing a risk of breakage and wobbling. Therefore, an additional protective sleeve needs to be added to the outside of the existing supercapacitor package to reduce the electrolyte distribution area, confining it within the protective sleeve. The tail section should be level with the front section to improve product lifespan.

[0023] like Figure 1 and Figure 2 As shown, the supercapacitor protective sleeve is based on the sleeve body 1, and its design fully considers both functionality and practicality. The sleeve body 1 is a shell with a first opening 1.1 on its upper surface, and is rectangular in shape with a U-shaped longitudinal section. This rectangular-U-shaped structure is not accidental, but rather the result of in-depth research into the shape characteristics and protection requirements of the supercapacitor 2. The rectangular shell structure is simple and clear, making the design of molds, injection molding, and subsequent processing relatively simple during the manufacturing process, effectively reducing production difficulty and manufacturing costs. The U-shaped longitudinal section is custom-designed according to the shape of the supercapacitor 2. After the supercapacitor 2 is installed in the sleeve body 1, the U-shaped structure can closely fit the side contour of the supercapacitor 2, wrapping the supercapacitor 2 from multiple directions, providing stable and firm support and protection, preventing the supercapacitor 2 from shaking or shifting inside the protective sleeve, and creating a safe and stable working environment for it.

[0024] The outer layer of the protective sleeve body 1 is made of highly flame-retardant and corrosion-resistant PP material, a choice of which has profound significance. In actual use, the supercapacitor 2 may generate high temperatures due to various reasons. Ordinary materials are prone to deformation and combustion under high-temperature environments, potentially leading to safety accidents. Highly flame-retardant PP material maintains its structural stability under high temperatures, effectively preventing the spread of flames and reducing the risk of fire, providing reliable fire protection for the supercapacitor 2 and surrounding equipment. Furthermore, in some special usage scenarios, the supercapacitor 2 may come into contact with corrosive substances. Ordinary materials are difficult to resist corrosion, leading to damage to the protective sleeve and affecting the performance and lifespan of the supercapacitor 2. Corrosion-resistant PP material, with its inherent chemical stability, effectively resists the erosion of various corrosive substances, ensuring that the protective sleeve will not break down due to corrosion during long-term use, thus extending the overall lifespan of the protective sleeve and indirectly guaranteeing the normal operation of the supercapacitor 2.

[0025] like Figure 1 As shown, the design of the first opening 1.1 on the upper surface of the protective sleeve body 1 also embodies ingenuity. On the one hand, the supercapacitor 2 generates heat during operation. If this heat cannot be dissipated in time, it will cause the internal temperature to rise, affecting the capacitor's performance and even causing malfunctions. The existence of the first opening 1.1 provides a channel for heat dissipation, allowing air to circulate between the inside and outside of the protective sleeve, accelerating heat conduction and convection, thereby effectively reducing the operating temperature of the supercapacitor 2, ensuring its operation within a suitable temperature range, and improving its performance and stability. On the other hand, by hollowing out part of the material, the first opening 1.1 reduces the overall weight of the protective sleeve without affecting its structural strength. The reduction in material usage directly lowers production costs, an advantage that is particularly significant in large-scale production, bringing considerable economic benefits to enterprises. The protective sleeve body 1 has flanges 1.5 on both sides, which are vertically upward and elastic. The flanges 1.5 connect with the curved surface of the protective sleeve body 1. The flanges 1.5 make the installation of the supercapacitor more convenient and stable.

[0026] like Figure 3As shown, the baffle 1.2 at one end of the protective sleeve body 1 is a key structure for achieving multiple layers of protection. The baffle 1.2 acts as a robust barrier, effectively preventing electrolyte leakage from the supercapacitor 2. During the use of the supercapacitor 2, electrolyte may overflow from the capacitor due to various factors. If the electrolyte flows to the outside of the supercapacitor 2, it will not only corrode surrounding electronic components but may also cause serious malfunctions such as short circuits. The baffle 1.2 can intercept the electrolyte leakage in time, preventing it from spreading to the outside of the protective sleeve, thereby protecting the safety of electronic equipment around the supercapacitor 2, reducing the risk of malfunctions caused by electrolyte leakage, and ensuring the stable operation of the supercapacitor 2.

[0027] like Figure 1 As shown, a second opening is provided at the other end of the protective sleeve body 1. The welding seat 1.3 at the bottom of the second opening and several slots 1.3.1 on it are the core components for achieving a stable connection between the protective sleeve and the PCB board. The slots 1.3.1 are rectangular and symmetrically distributed on both sides of the welding seat 1.3. In actual installation, the solder pads can be accurately inserted into the slots 1.3.1. The slots 1.3.1 provide precise positioning for the solder pads, ensuring that the solder pads are in the correct position during soldering, greatly improving the accuracy and reliability of the soldering. By soldering the welding seat 1.3 of the protective sleeve body 1 to the PCB board, a firm connection between the protective sleeve and the PCB board is achieved. This connection method is tight and stable. During equipment operation, even when faced with vibration, external impact, etc., the protective sleeve will not easily loosen or fall off, always maintaining a reliable connection with the PCB board, ensuring the normal operation of the supercapacitor 2 in the circuit. At the same time, this design is highly compatible with the existing supercapacitor 2 installation method, without the need for large-scale modification of the existing PCB board design and equipment installation process. It is only necessary to solder the protective sleeve to the corresponding position according to conventional soldering operations.

[0028] Several balance columns 1.4, located on the lower surface of the protective sleeve body 1 on the side of the baffle 1.2, also play a crucial role in improving the performance of the protective sleeve. These balance columns 1.4 are symmetrically and evenly distributed along the axis of symmetry of the protective sleeve body 1, a layout supported by sound mechanical principles. During installation, the symmetrically and evenly distributed balance columns 1.4 ensure uniform force distribution between the protective sleeve, the supercapacitor 2, and the PCB board, preventing installation deviations or instability caused by uneven force. During equipment operation, whether subjected to minor vibrations during normal operation or larger external impacts, the balance columns 1.4, through their support, maintain good balance of the protective sleeve, preventing displacement or swaying due to a shift in the center of gravity. This good balance not only improves the fitting accuracy between the protective sleeve, the supercapacitor 2, and the PCB board but also reduces damage to the supercapacitor 2 and its connections caused by vibration or external forces, thereby enhancing the stability and reliability of the entire device and further extending the service life of the supercapacitor 2 and related equipment.

[0029] like Figure 2 As shown, the balance column 1.4, as a crucial component ensuring the stability of the protective sleeve, is designed to fully embody the combination of functionality and practicality. The balance column 1.4 consists of small rectangular blocks symmetrically distributed on both sides of the lower surface of the protective sleeve body 1. This small rectangular block structure offers significant ease of manufacturing, from mold forming to subsequent cutting and polishing. Compared to more complex structures, the small rectangular blocks have a simpler manufacturing process, higher production efficiency, and can effectively reduce production costs. From a mechanical perspective, the symmetrically arranged balance columns 1.4 act as stable fulcrums, evenly distributing the forces from the supercapacitor 2 above and the external environment during the placement or installation of the protective sleeve. When the protective sleeve is subjected to external impact or vibration, the symmetrically distributed balance columns 1.4 prevent excessive localized stress, avoiding deformation or damage to the protective sleeve body 1 due to stress concentration. They also ensure the stability of the connection between the protective sleeve and the PCB board, preventing loosening due to uneven stress.

[0030] The lower surfaces of the balance column 1.4 and the soldering base 1.3 are on the same horizontal plane. This precise design ensures that the bottom of the protective sleeve body 1 remains absolutely flat when placed on a flat surface or mounted on a PCB board. This flat bottom not only makes it easier to align and position the protective sleeve during installation, reducing installation errors, but also ensures a tighter and more uniform contact between the protective sleeve and the PCB board. In practical applications, this stability effectively prevents uneven stress on the internal structure of the supercapacitor 2 caused by tilting or shaking of the protective sleeve, thereby reducing electrical performance degradation caused by mechanical stress. For example, during equipment operation, even in a vibrating environment, the balance column 1.4 and the soldering base 1.3, being on the same horizontal plane, ensure that the protective sleeve remains stable, maintaining the normal operation of the supercapacitor 2.

[0031] The welding base 1.3 is rectangular, with a simple and straightforward structure that facilitates standardized production, whether through stamping or injection molding. The rectangular shape of the welding base 1.3 provides ample welding area; when the protective sleeve body 1 is connected to the PCB board via the welding base 1.3, the larger welding area translates to more welding points and stronger connection force. During welding, operators can more easily control the welding quality, ensuring even distribution of solder on the surface of the welding base 1.3 and reducing welding defects such as incomplete soldering and detachment, thus achieving a firm and reliable connection between the protective sleeve body 1 and the PCB board. Even after long-term operation and repeated vibrations and temperature changes, this strong connection ensures that the protective sleeve will not detach from the PCB board.

[0032] The design of the upper surface of the welding base 1.3 being flush with the inner wall of the bottom of the protective sleeve body 1 further optimizes the internal space layout of the protective sleeve. When the supercapacitor 2 is installed inside the protective sleeve body 1, the flat bottom space provides a neat and safe installation environment for the supercapacitor 2. If the upper surface of the welding base 1.3 protrudes from the inner wall of the bottom of the shell, it may cause pressure on the capacitor shell during the installation of the supercapacitor 2, or even damage the capacitor's electrodes or other critical components. The flush design completely avoids this risk, allowing the supercapacitor 2 to be installed smoothly and safely. Furthermore, after installation, the fit between the supercapacitor 2 and the protective sleeve body 1 is tighter, further enhancing the protective sleeve's fixing effect on the supercapacitor 2.

[0033] The baffle 1.2, as the core component of the protective sleeve to achieve multiple protective functions, consists of a side plate 1.2.1 and a top cover 1.2.2, and is located at the tail end of the supercapacitor 2. The side plate 1.2.1 is upright and tightly covers the outer surface of the tail end of the supercapacitor 2. In actual use scenarios, harmful substances such as dust, impurities, and moisture are ubiquitous. The side plate 1.2.1 acts as a protective barrier, effectively preventing these substances from entering the supercapacitor 2. The intrusion of dust and impurities may cause short circuits or poor contact inside the supercapacitor 2, while moisture may corrode the capacitor's electrodes and internal materials, severely affecting the performance and lifespan of the supercapacitor 2. The sealing and protective function of the side plate 1.2.1 greatly improves the reliability of the supercapacitor 2 in harsh environments and extends its service life.

[0034] like Figure 3As shown, the top cover 1.2.2 adopts a U-shaped structure, covering the tail end of the supercapacitor 2. The U-shaped design fully conforms to the shape of the tail end of the supercapacitor 2, providing all-around protection from the top. During equipment handling, installation, or operation, the top of the tail end of the supercapacitor 2 may be subjected to collisions or pressure from external objects. The U-shaped top cover 1.2.2 can effectively buffer these external forces, preventing damage to the supercapacitor 2 from direct impact. In addition, when electrolyte leakage occurs in the supercapacitor 2, the U-shaped structure can guide the electrolyte to flow in a specific direction, preventing electrolyte accumulation above the tail end and reducing the risk of electrolyte corrosion to other parts of the supercapacitor 2 and surrounding electronic components, further enhancing the protective performance of the protective cover.

[0035] The welding base 1.3 is located at the front end of the supercapacitor 2, and the front and rear ends of the supercapacitor 2 are at the same horizontal height. This design reflects a deep consideration of the operational stability of the supercapacitor 2. Maintaining a horizontal position is crucial for the uniform distribution of the internal electric field and electrolyte during the operation of the supercapacitor 2. If the supercapacitor 2 is tilted, it may lead to uneven distribution of the internal electric field, affecting the charging and discharging performance of the capacitor, and even causing electrical faults. The front welding base 1.3 and the rear balance column 1.4 work together to ensure that the supercapacitor 2 remains horizontal after installation. This consistent horizontal design allows the supercapacitor 2 to maintain the stability of its internal structure during operation, reduces stress concentration caused by tilting, and ensures stable performance of its electrical components.

[0036] The protective sleeve of this utility model demonstrates significant beneficial effects in practical applications. In mass production, its standardized structural design and simple installation method allow workers to quickly and accurately install the protective sleeve onto the supercapacitor 2 and the PCB board. The fit between the rectangular welding base 1.3 and the slot 1.3.1, as well as the flat bottom design of the balance column 1.4 and the welding base 1.3, reduce adjustment time and errors during installation, greatly improving production efficiency. During end-use, the baffle 1.2 provides comprehensive protection to the tail end of the supercapacitor 2, effectively preventing electrolyte leakage and splashing, avoiding electrolyte corrosion of other electronic components on the circuit board, and ensuring the safe operation of the entire circuit system. Meanwhile, the first opening 1.1 on the upper surface of the protective sleeve body 1 continuously functions as a heat dissipation device, ensuring that the heat generated by the supercapacitor 2 during operation can be dissipated in a timely manner, maintaining its operation within a suitable temperature range, extending the service life of the supercapacitor 2, and improving the overall reliability of the equipment.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
