Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, specifically to a high-voltage solid capacitor. Background Technology

[0002] With the rapid development of modern electronic technology, solid-state capacitors, as an important component of electronic systems, directly affect the operational efficiency and safety of the entire electronic system through their stability and reliability. Solid-state capacitors have advantages such as small size, light weight, large capacitance, and long lifespan, and are widely used in power supply filtering, energy storage, and pulse discharge. However, as electronic systems increasingly demand higher voltage withstand capabilities from capacitors, existing solid-state capacitors face severe challenges in terms of voltage withstand performance, heat dissipation, and safety. Existing solid-state capacitors and their internal encapsulation materials are unable to withstand high pressures and cannot provide sufficient protection for internal components. When external pressure increases, the casing may rupture, exposing internal components, damaging not only the capacitor itself but also potentially affecting the normal operation of the entire circuit system. Utility Model Content

[0003] The purpose of this invention is to provide a high-voltage solid-state capacitor to solve the problem of low structural strength of existing solid-state capacitors mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-voltage solid-state capacitor includes a solid-state capacitor body, and a high-voltage-resistant outer shell and a sealing cap are fitted onto the surface of the solid-state capacitor body.

[0006] The high pressure-resistant outer shell includes an inner core, the surface of which is provided with a pressure-resistant outer shell, and the inner wall of which is provided with an explosion-proof inner layer.

[0007] One end of the high pressure resistant housing is an open structure, and the edge of the open is provided with a plug-in groove. Several sets of evenly spaced locking bolts are installed on the edge of the open end of the high pressure resistant housing.

[0008] The sealing cover is equipped with a plug-in ring head that is adapted to the size of the plug-in groove and is plugged in. The outer wall of the plug-in ring head is provided with a fixing screw hole that is the same number as the locking bolts, corresponding in position, adapted in size, and threadedly connected.

[0009] Preferably, the solid capacitor body is equipped with pins connected to the positive and negative terminals.

[0010] Preferably, the sealing cover has pin through holes that are adapted to the pin size and can be inserted into the pin.

[0011] Preferably, the height of the plug ring is one-sixth to one-fifth of the height of the high-pressure resistant housing.

[0012] Preferably, the outer wall of the pressure-resistant shell is provided with an anti-corrosion coating.

[0013] Preferably, the inner wall of the explosion-proof inner layer is equipped with several sets of evenly spaced heat dissipation protrusions.

[0014] Preferably, the heat dissipation protrusion is made of high-temperature resistant rubber, and the height of the protrusion is 5-8mm.

[0015] Compared with existing technologies, the beneficial effects of this utility model are:

[0016] This high-voltage solid-state capacitor features a high-voltage outer shell, composed of an inner core, a pressure-resistant outer shell, and an explosion-proof inner layer. The pressure-resistant outer shell enhances the overall pressure resistance, while the explosion-proof inner layer prevents the spread of explosive hazards in abnormal situations. The opening structure and insertion groove of the high-voltage outer shell mate with the insertion ring of the sealing cap, and are then connected to the threaded fixing screw hole by locking bolts to achieve a tight seal, preventing external factors from affecting the solid-state capacitor body. At the same time, the sealing cap further protects the solid-state capacitor body, giving this high-voltage solid-state capacitor excellent pressure resistance, sealing, and explosion-proof performance, improving product safety and stability, and extending its service life.

[0017] In this high-voltage solid capacitor, the outer wall of the high-voltage casing is provided with an anti-corrosion coating. This anti-corrosion coating can effectively isolate the high-voltage casing from corrosive substances or environments, preventing the casing from being corroded and damaged. This ensures the structural strength and integrity of the high-voltage casing, thereby ensuring that the solid capacitor can operate reliably in various complex environments and extending the product's service life.

[0018] In this high-voltage solid-state capacitor, several sets of evenly spaced heat dissipation protrusions are installed on the inner wall of the explosion-proof inner layer. The heat dissipation protrusions are made of high-temperature resistant rubber. By setting the heat dissipation protrusions, the heat dissipation range between the solid-state capacitor body and the explosion-proof inner layer is increased, preventing local overheating. The use of high-temperature resistant rubber protrusions can not only meet the heat dissipation requirements, but also play a certain role in buffering and blocking when the capacitor reaches abnormally high temperatures or may even explode, thereby enhancing the explosion-proof effect and ensuring safe use.

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.

They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] A high-voltage solid capacitor, such as Figures 1-3As shown, the device includes a solid-state capacitor body 10, with a high-voltage resistant outer shell 20 and a sealing cap 30 fitted onto its surface. The high-voltage resistant outer shell 20 includes an inner core 201, with a pressure-resistant outer shell 202 on its surface and an explosion-proof inner layer 204 on its inner wall. One end of the high-voltage resistant outer shell 20 is open, with a insertion groove 21 at the edge of the opening. Several sets of evenly spaced locking bolts 22 are installed at the edge of the open end of the high-voltage resistant outer shell 20. The sealing cap 30 is equipped with a plug-in ring head 31 that matches the size of the insertion groove 21 and is plugged in. The outer wall of the plug-in ring head 31 has the same number of locking bolts 22, corresponding in position, and matching in size, and is threadedly connected to them. The fixed screw hole 32, through the high-pressure resistant outer shell 20, is composed of an inner core 201, a pressure-resistant outer shell 202, and an explosion-proof inner layer 204. The pressure-resistant outer shell 202 enhances the overall pressure resistance, and the explosion-proof inner layer 204 can prevent the spread of explosion hazards in abnormal situations. The opening structure and insertion groove 21 of the high-pressure resistant outer shell 20 cooperate with the insertion ring head 31 of the sealing cover 30, and are then connected to the fixed screw hole 32 by the locking bolt 22, achieving a tight seal and preventing external factors from affecting the solid capacitor body 10. At the same time, the sealing cover 30 can further protect the solid capacitor body 10, so that the high-pressure resistant solid capacitor has good pressure resistance, sealing and explosion-proof performance, improving the safety and stability of the product and extending its service life.

[0029] Furthermore, the solid capacitor body 10 is equipped with pins 11 connected to the positive and negative terminals, and the sealing cover 30 has pin through holes 33 that are adapted to the size of the pins 11 and can be plugged in. Through the pins 11, the solid capacitor body 10 can be easily electrically connected to the external circuit. The fitting and plugging of the pin through holes 33 and the pins 11 ensures that the pins 11 can be led out normally, while maintaining the sealing effect of the sealing cover 30 on the opening of the high-voltage housing 20, preventing external impurities, moisture and other substances from entering and affecting the performance of the capacitor.

[0030] It is worth noting that the height of the plug ring 31 is one-sixth to one-fifth of the height of the high-voltage housing 20. By setting the height of the plug ring 31 within a specific ratio range, when the sealing cover 30 and the high-voltage housing 20 are connected, sufficient insertion depth can be ensured to provide a stable connection structure, enhancing the overall sealing and stability, while the compactness and space layout of the entire capacitor will not be affected by the excessive height of the plug ring 31.

[0031] Specifically, the outer wall of the pressure-resistant housing 202 is provided with an anti-corrosion coating 203. The anti-corrosion coating 203 can effectively isolate the pressure-resistant housing 202 from corrosive substances or environments, prevent the housing from being corroded and damaged, thereby ensuring the structural strength and integrity of the high-pressure-resistant housing 20, and thus ensuring that the solid-state capacitor can operate reliably in various complex environments and extend the service life of the product.

[0032] In addition, several sets of evenly spaced heat dissipation protrusions 205 are installed on the inner wall of the explosion-proof inner layer 204. The heat dissipation protrusions 205 are made of high-temperature resistant rubber and the height of the protrusions is 5-8mm. By setting the heat dissipation protrusions 205, the heat dissipation range between the solid capacitor body 10 and the explosion-proof inner layer 204 is increased, preventing local overheating. The use of high-temperature resistant rubber protrusions can not only meet the heat dissipation requirements, but also play a certain role in buffering and blocking when the capacitor has abnormal high temperature or may even explode, thereby enhancing the explosion-proof effect and ensuring safe use.

[0033] The working principle of this high-voltage solid capacitor:

[0034] First, prepare for installation by checking whether the solid capacitor body 10 is intact and whether the pins 11 are bent or damaged. Also, confirm that the high-voltage housing 20's pressure-resistant housing 202, explosion-proof inner layer 204, and other structures are undamaged and that the anti-corrosion coating 203 is not peeled off.

[0035] Next, the installation and connection are carried out. The pins 11 of the solid capacitor body 10 are passed through the pin through holes 33 on the sealing cover 30, so that the solid capacitor body 10 is located in a suitable position below the sealing cover 30. Then, the sealing cover 30 with the solid capacitor body 10 is inserted into the insertion groove 21 on the edge of the opening of the high-voltage housing 20 through the insertion ring head 31 on the sealing cover 30. The locking bolt 22 is used to connect with the fixing screw hole 32 on the outer wall of the insertion ring head 31. The bolt is tightened so that the sealing cover 30 and the high-voltage housing 20 are tightly combined to form a closed space to protect the solid capacitor body 10.

[0036] Finally, the electrical connection is made by connecting the capacitor to the positive and negative terminals of the external circuit through pin 11, and it can then be put into use. During use, the heat dissipation protrusion 205 will help dissipate the heat generated by the solid capacitor body 10, the anti-corrosion coating 203 will protect the pressure-resistant outer shell 202 from external corrosion, and the explosion-proof inner layer 204 will prevent the spread of explosion hazards in abnormal conditions, ensuring the safe and stable operation of the capacitor.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
