Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic capacitors, in particular to an electrode component for an electrolytic capacitor and an electrolytic capacitor. BACKGROUND

[0002] An electrolytic capacitor is a capacitor with metal as an anode and an insulating dielectric layer formed on its surface by oxidation, and an electrolyte as an actual cathode in contact with the oxide film to form a conductive layer. Its core structure includes anode metal foil, oxide film dielectric layer, electrolyte cathode and sealed shell. The working principle is based on the proportional relationship between the thickness of the oxide film and the applied voltage to achieve high-capacity charge storage. It has the characteristics of large capacity per unit volume, low cost, clear polarity, etc. Typical application scenarios include power filtering, coupling and decoupling, energy storage and timing circuits.

[0003] When the current and voltage of the electrolytic capacitor exceed the limit, the shell is prone to bulging, cracking and even explosion. The existing protection device can only block the splashing of fragments and electrolyte when the capacitor explodes, avoiding affecting the surrounding structure, but it cannot cut off the connection pin in time when the temperature of the capacitor abnormally rises due to the current and voltage exceeding the limit. When the internal dielectric layer of the electrolytic capacitor withstands an electric field strength exceeding its tolerance limit, the dielectric layer will be broken down, causing internal short circuit, and the capacitor will be completely damaged. At the same time, the electrolyte will be rapidly vaporized due to the action of large current, causing the internal pressure to increase dramatically, eventually causing the shell to burst, the electrolyte to splash, and even a fire induced by the flammability of the electrolyte.

DETAILED DESCRIPTION

[0035] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0036] Referring to Figures 1-10 As shown in the drawings, the present application provides an electrode component for an electrolytic capacitor and an electrolytic capacitor, comprising: a protection mechanism 2, two shearing mechanisms 3 are fixedly installed on the outer wall of the protection mechanism 2, and an electrolysis mechanism 1 is fixedly inserted in the inside of the protection mechanism 2.

[0037] When the electrolytic capacitor is working, it first enters the normal charge storage and release stage. In the electrolysis mechanism 1, the ions in the electrolyte will migrate under the driving of the current, the positive electrode will gather electrons, and the negative electrode will adsorb ions, thereby forming an electric field and realizing the storage of electric charge. When discharging is needed, the stored electric charge will be orderly released through the external circuit, thereby providing the required electric energy for the external circuit and completing the basic capacitance function. In actual use, when the current voltage exceeds the limit or the electrodes are connected in reverse, etc., a violent chemical reaction will occur inside the electrolytic capacitor, causing the internal temperature to rise continuously. With the continuous rise in temperature, the electrolyte will decompose and generate a large amount of gas. The accumulation of these gases will cause the pressure on the shell to increase continuously, and eventually may cause the shell to crack. When the shell cracks, the heat and related gas generated inside the electrolytic capacitor will be rapidly released into the protection mechanism 2. At this time, the air in the protection mechanism 2 will expand due to heating, and in addition to the large amount of gas injected from the inside of the electrolytic capacitor, the volume and air pressure inside the protection mechanism 2 will increase sharply. This change in volume and air pressure will generate a strong driving force to drive the shearing mechanism 3 to move. The shearing mechanism 3 will act on the two pins 14 at the bottom during movement, cutting them off. After the pins 14 are cut off, the connection between the electrolytic capacitor and the external circuit is completely disconnected, thereby avoiding further deterioration of abnormal conditions and effectively preventing the electrolytic capacitor from exploding. However, even if the above measures are taken, in some extreme cases, an explosion may still be unavoidable. If the electrolytic capacitor really explodes, the shock wave generated will be promptly discharged from the corresponding channel reserved in the protection mechanism 2, avoiding greater damage to the surrounding environment due to the accumulation of shock waves. At the same time, the protection mechanism 2 also has an interception function, which can effectively intercept the splashing electrolyte and fragments. The electrolyte is corrosive, and the fragments may have high kinetic energy. If they splash around, they may cause damage to nearby equipment. The protection mechanism 2, through its special material and structural design, can intercept these dangerous substances and ensure the safety of nearby equipment.

[0038] In some instances, reference Figures 2-5 As shown, it includes an electrolysis mechanism 1, which includes:

[0039] The outer wall of the shell 11 is fixedly installed with a group of heat sinks 12, and the outer walls of a group of heat sinks 13 are fixedly installed on the surface of the shell 11. The outer walls of a group of heat sinks 12 and a group of heat sinks 13 are fixedly inserted into the inside of the protective cover 21. The bottom of the shell 11 is provided with two pins 14, and the outer walls of the two pins 14 are fixedly inserted into the inside of the shell 11 and the mounting frame 31. The bottom of the inner wall of the shell 11 is provided with a central column 15, and the outer wall of the central column 15 is wrapped with two aluminum foil bodies 16 and two electrolytic papers 17. The aluminum foil body 16 includes an aluminum foil sheet 161, and the outer wall of the aluminum foil sheet 161 is provided with a nickel coating 162. The outer walls of the two aluminum foil bodies 16 are each provided with a group of liquid permeable holes 18, and the inner walls of the two groups of liquid permeable holes 18 are both provided with a boron nitride coating 19.

[0040] When the external current is input into the electrolytic capacitor through the pin 14, first, the anode aluminum foil body 16 starts the charge storage process, and the charges brought by the current continuously gather on its surface, making it carry a positive charge, laying a solid foundation for charge storage and release. At the same time, the cathode aluminum foil body 16 acts as a smooth current channel, smoothly guiding the current to various parts of the capacitor, providing current support for subsequent electrochemical reactions and charge storage. The electrolytic paper 17 soaked in the electrolyte stores a large amount of electrolyte. After being powered on, the conductive ions in the electrolyte move directionally along the pores of the electrolytic paper 17 under the action of the electric field, forming a virtual cathode on the surface of the dielectric layer, which echoes the charges on the anode aluminum foil body 16, realizing effective charge storage. When the charges are released, the charges stored on both are quickly released through the external circuit. The surface of the aluminum foil body 16 is coated with nickel, effectively isolating the aluminum foil from the air, preventing aluminum oxidation, avoiding changes in the electrical properties of the aluminum foil due to the aluminum oxide layer, maintaining the stability of the electrode for a long time, ensuring that the aluminum foil always has good electrical conductivity and charge storage capacity. At the same time, the nickel layer enhances the corrosion resistance of the aluminum foil, resists electrolyte erosion, protects the aluminum foil from damage, extends its service life, and ensures the overall performance of the capacitor. The liquid-permeable hole 18 on the outer wall of the aluminum foil body 16 greatly increases the contact area between the aluminum foil and the electrolyte, allowing the electrolyte to penetrate deeply into the aluminum foil, making the contact more complete and the ion migration path shorter and more smooth. During charge storage and release, ions can quickly and uniformly migrate, reducing the equivalent series resistance and energy loss when current passes through, allowing the capacitor to store and release electrical energy more efficiently. It also improves high-frequency characteristics to meet the needs of high-frequency circuits, while improving charging and discharging efficiency, shortening charging and discharging time, and improving circuit efficiency. The boron nitride coating 19 on the inner wall of the hole significantly improves the thermal management performance of the capacitor. The boron nitride coating 19 has excellent thermal conductivity, acting as an efficient heat dissipation channel to quickly conduct Joule heat out and exchange heat with the outside through the shell 11, effectively reducing the core temperature. Reducing the core temperature slows down the evaporation of the electrolyte and the aging rate of the medium, providing a stable working environment for the medium, reducing aging, extending the service life of the capacitor, and ensuring its long-term performance stability.

[0044] When the electrolytic capacitor is running under abnormal conditions, such as encountering overcurrent, overvoltage and the like, the temperature inside the protective sleeve 21 gradually rises, at the same time, the electrolytic capacitor inside may appear gas leakage due to structural damage and the like, these leaked gas continues to inject into the protective sleeve 21, with the continuous rise of temperature and the continuous injection of gas, the pressure inside the protective sleeve 21 begins to increase, in the process of the continuous rise of the gas pressure, when reaching a certain pressure value, the gas pressure will generate a large enough thrust to push the piston 26 at the top of the protective sleeve 21 to slowly rise, and the piston 26 at the top is connected with the tooth column 211, both are closely connected and move synchronously, so when the piston 26 rises, the tooth column 211 also rises synchronously, the tooth column 211 drives the related mechanism to move, triggering a series of mechanical actions, and finally timely cutting off the lead 14, which is like cutting off the connection between the electrolytic capacitor and the external circuit, can quickly stop the abnormal current from continuing to flow, avoid the situation from further deteriorating, prevent the electrolytic capacitor from being damaged more seriously, and protect the safety of the entire circuit system, if the abnormal situation is too serious, the electrolytic capacitor has exploded, the protective sleeve 21 can effectively intercept the shock wave, reduce the impact force of the shock wave on the surrounding elements, at the same time, it can also intercept the splashed electrolyte and fragments, prevent these dangerous substances from contacting the surrounding elements, avoid the surrounding elements from being damaged, thereby protecting the safety of the entire electronic device, under the action of the strong impact force generated by the explosion, the shock wave will push the piston 26 to quickly rise to the top, the protective sleeve 21 is provided with a push rod 24 at the top, when the piston 26 rises to the top, the push rod 24 will be inserted into the movable hole 27, the movable hole 27 is internally provided with a sealing plug 210, after the push rod 24 is inserted, it will contact the sealing plug 210, under the pushing of the push rod 24, the sealing plug 210 will stretch the spring one 29, so that the sealing plug 210 is pulled out of the movable hole 27, a channel is formed between the inside of the protective sleeve 21 and the outside, and the excess gas inside will be discharged through the movable hole 27, in the process of discharging the gas, the protective sleeve 21 is further provided with an interception net 25 at the top, the interception net 25 can further intercept small fragments, prevent these small fragments from being taken to the outside by the gas, avoid polluting the external environment or damaging other equipment, and then the gas filtered by the interception net 25 is discharged to the outside through the exhaust valve 23.

[0048] When the gear column 211 begins to rise under the push of air pressure, it will first drive the gear 1 33 meshing with it to rotate around the outer wall of the fixed rod 1 32, and the gear 1 33 will drive another rack 34 meshing with it to start descending. During the descent of the rack 34, the slider 1 35 fixedly installed on one side of its outer wall will be driven accordingly and slide synchronously inside the pre-set slide groove 1 36. The sliding of the slider 1 35 in the slide groove 1 36 will produce an extrusion effect on the spring 1 29 below. As the rack 34 continues to descend, its bottom end teeth will mesh with the gear 2 310 and drive the gear 2 310 to rotate around the surface of the fixed rod 2 38. The rotation of the gear 2 310 will drive the bevel gear 1 39 fixed to it to start rotating.

The rotation of gear 4 315 will drive gear 5 317 meshing with it to rotate around the surface of fixed rod 5 316. Since the diameters of gear 313, gear 4 315 and gear 5 317 are arranged in order of large, medium and small, according to the principle of gear transmission, in the same time, the number of circles of the small diameter gear will be more than that of the large diameter gear. Therefore, the rotation speeds of the three will gradually increase. This forms an effect of speed-increasing transmission. When gear five 317 reaches a high-speed rotation state, it drives the two driving tooth blocks 323 on its outer wall to move in different directions. The movement of the two driving tooth blocks 323 drives the top slider 2 319 to slide inside the guide rail 1 318, and makes the two sliders 2 319 approach each other. As the sliders 2 319 approach each other, the two mounting rods 320 on their tops will also approach each other.

The two connecting force arms 321 will rotate with the rotating shaft 1 322 at the center as the center of the circle, so that their top ends will also approach each other. The approach of the top ends of the connecting force arms 321 will drive the rotating shaft inserted inside. The two shafts 324 move synchronously, and the movement of the second shaft 324 will make the rollers 325 on the outer walls thereof approach each other and roll inside the second guide rail 330. Since the connecting force arm 321 rotates in the vertical direction at this time, the second shaft 324 will be driven forward in the process of approaching, and the second shaft 324 will push the second guide rail 330 through the roller 325, so that the second guide rail 330 moves. The movement of the second guide rail 330 will drive the slider 329 installed on its outer wall to slide inside the second slide groove 328. As the two shafts 324 approach each other, the ends of the two shearing knives 326 will be driven to approach each other. The two shearing knives 326 will rotate with the shaft 3 327 as the center of the circle, thereby driving the shearing parts of their front ends to approach each other. Finally,The front end of the shearing knife 326 can accurately cut the pin 14 at the bottom of the electrolytic capacitor, so that the circuit is quickly closed. This series of mechanical actions can timely cut off the circuit when the electrolytic capacitor is in an abnormal condition, avoid further deterioration of the electrolytic capacitor, effectively prevent the occurrence of serious safety accidents such as explosion and even fire, and thus ensure the safe operation of the entire electronic equipment.
