[0028] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0029] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0030] like Figure 1 As shown, a high-voltage electrical component of this application includes a housing 1, a seal 2, a fastener 3, a support frame 4, and a conductive contact 5. The following describes each component, its structure, installation position, and connection method in detail.

[0031] The housing 1 is a core component used to house high-voltage electrical components and form a sealed chamber. Through its design and material selection, the housing 1 can withstand pressure changes in the external environment and possesses sufficient mechanical strength to ensure the safe operation of the internal high-voltage electrical components. Furthermore, the housing 1 has multiple openings for mating and installation with other parts. For example, its connections are pre-installed with standard flange structures to match the assembly of the seals 2, while its walls have internal and external threaded structures to support fasteners 3 for a secure connection.

[0032] The seal 2 is installed at the connection of the housing 1, playing a crucial role in preventing external moisture from entering the chamber. This seal 2 is made of a flexible polymer material and has a special corrugated structure 21 (see details). Figure 3 and Figure 4 This design significantly enhances the elastic recovery capability of the seal 2 under compression, allowing it to adapt to various geometric deformation requirements under external forces. Simultaneously, the seal 2 features a raised pre-tightening ring 22, which increases the surface friction between it and the housing 1, thereby improving sealing reliability. Furthermore, the seal 2 includes radial adjustment grooves 23, which can adjust the prestress distribution in different areas of the seal 2, flexibly meeting different sealing force requirements according to actual conditions.

[0033] Fastener 3 is threaded to the outside of housing 1 and is used to press the seal 2. Fastener 3 is generally made of high-strength alloy material to avoid deformation and failure that may occur under high pressure. One end has a precisely fitted threaded hole structure for easy manual or mechanical tightening, while the other end has a flat pressing surface design that directly contacts the seal 2 and applies sufficient pre-tightening pressure, ensuring that the seal 2 is firmly fitted into the mating surface between housings 1 during installation.

[0034] The support frame 4 is fixed inside the housing 1 to provide mechanical support and prevent high-voltage electrical components from being damaged or loosened due to their own weight or other external forces. Specifically, the bottom of the support frame 4 is fixed to the inner wall of the housing 1 by welding or snap-fit, thereby ensuring stability. Its main structure is usually a perforated grid structure, which reduces the overall weight while effectively distributing pressure. For example, aluminum with multi-directional reinforcing ribs can be used as the raw material to make the support frame 4, which satisfies the mechanical strength requirements while reducing manufacturing costs.

[0035] The conductive contact 5 is arranged on the housing 1, enabling the transmission of high-voltage current to external circuits. The conductive contact 5 is generally made of a highly corrosion-resistant conductive metal material. To facilitate compatibility with connection interfaces of other electrical devices, the surface of the conductive contact 5 may undergo a special coating treatment or be equipped with a standardized terminal block structure. In specific applications, the conductive contact 5 can be isolated from its surrounding space using insulating gaskets or sleeves to reduce the risk of leakage and ensure stable system operation.

[0036] To address the technical challenge of preventing leakage in high-humidity environments, this application comprehensively optimizes the overall design of the sealing system. Firstly, the flexibility and durability are enhanced by employing a seal 2 with a corrugated structure 21, allowing it to adapt to minor deformations caused by temperature differences. Next, the addition of a pre-tightening ring 22 improves friction and connection stability, preventing the intrusion of external moisture. Furthermore, the introduction of a radial groove mechanism that adjusts the sealing stress ensures the entire assembly maintains excellent sealing under a wide range of operating conditions. Combined with highly efficient fasteners 3 and a well-designed stress-distribution structure, this electrical component is less prone to leakage of liquid or gaseous media even under extremely high humidity conditions, significantly improving operational reliability and applicability.

[0037] like Figure 2 As shown, in one embodiment, the sealing element 2 of a high-voltage electrical component of this application employs a special structural design to achieve superior flexible deformation performance. Specifically, the corrugated structure 21 of the sealing element 2 comprises three layers of annular stacked structures 24. Flexible gaskets 25 are provided between each layer of annular structure for separation. This layered structure helps to improve the overall deformation adaptability, especially under the mechanical stress of a high-voltage environment, and can better meet the flexible adjustment requirements.

[0038] The specific implementation of the aforementioned three-layer annular stacked structure 24 can be achieved by selecting appropriate materials and processing techniques. For example, a flexible material with a certain elastic recovery capability can be selected to manufacture each layer of the annular structure, and the flexible gasket 25 can be precisely embedded into the gaps between the annular structures through precision assembly, thereby ensuring that the parts can be stably connected and deform in coordination. In addition, when the seal 2 is installed at the connection of the housing 1, the clamping action of the fastener 3 further ensures that these stacked layers are tightly fitted with the surrounding components, guaranteeing that the overall structure has reliable stability and good sealing performance.

[0039] like Figure 3 and Figure 4 As shown, in one embodiment, the pre-tightening portion of the seal 2 of a high-voltage electrical component of this application has been optimized to further enhance its connection reliability. Specifically, the pre-tightening ring 22 has a multi-tooth structure with multiple sets of anti-slip ridges 26 evenly arranged along the circumference of the seal 2. This structural form significantly increases the surface area of ​​the contact area between the pre-tightening ring 22 and the housing 1, and generates stronger friction by increasing the surface roughness. Therefore, under high-pressure conditions, even with large vibrations or temperature stress changes, the tightness of the connection can be effectively maintained, thereby better ensuring the overall sealing performance of the electrical component.

[0040] For example, in manufacturing seal 2, a preload ring 22 region with multi-tooth characteristics is constructed using mold forming technology, and then uniformly distributed anti-slip ridges 26 are precisely machined circumferentially using a secondary processing method. These anti-slip ridges 26 are installed on the side of the preload ring 22 facing the inside of the housing 1 and directly contact the surface of the housing 1 after the fasteners 3 are tightened, thereby ensuring a consistently high level of stability and reliable sealing throughout the entire installation and operation process. Furthermore, this design also considers production efficiency and ease of assembly, ensuring smoother and more error-free operation between components.

[0041] like Figure 2 As shown, in one embodiment, the housing 1 of a high-voltage electrical component of this application employs a special design at its connecting end to assist in the precise alignment of the seal 2 during installation. Specifically, the housing 1 has a ring of inclined guide surfaces 11 along its connecting edge. These inclined guide surfaces 11 form a specific angle with the horizontal plane and extend outwards from the housing 1. This inclined guide surface guides the seal 2 to slide along the correct trajectory and approach the connecting portion of the housing 1, avoiding air leakage or poor contact problems caused by misalignment of the seal 2. This design is particularly suitable for sealing operations in situations requiring multiple disassemblies and reassemblies, while also simplifying the complexity of alignment operations.

[0042] For example, the required inclined guide structure can be formed during the manufacturing process of housing 1 through metal stretching or machining, ensuring a smooth, continuous, and burr-free structure to prevent damage to seal 2. During installation, seal 2 gradually approaches the connection point of housing 1 along this inclined guide surface under external pressure, thereby achieving automatic centering. Furthermore, this feature, when used in conjunction with existing fasteners 3, further enhances the overall sealing performance of the connection point of housing 1 without altering the position or connection method of other components.

[0043] like Figure 2 As shown, in one embodiment, a structural feature is added inside the housing 1 of a high-voltage electrical component of this application to assist the sealing element 2 in achieving a more reliable pre-tightening fit. Specifically, this structure is an elastic pressure ring 12 located inside the housing 1, corresponding to the assembly position of the sealing element 2. This elastic pressure ring 12 is made of a material with a certain elastic recovery capability, enabling it to form a good contact fit with the sealing element 2 under the pressure applied by the fastener 3. Through its own elastic deformation properties, the pressure ring not only provides continuous support for the sealing element 2 but also significantly enhances the overall structure's adaptability to high-humidity environments.

[0044] For example, the elastic pressure ring 12 can be designed as a thin annular sheet, with its outer edge fixed to the corresponding area of ​​the inner wall of the housing 1 by snap-fit ​​or interference fit, while its inner edge faces the outer peripheral area of ​​the seal 2, forming a tight circumferential contact band. After further axial pressure is applied by the fastener 3, the elastic pressure ring 12 will be slightly compressed and continuously provide rebound force to help the seal 2 maintain deformation fit, thereby improving sealing performance. Throughout the installation process, the position and connection form of the elastic pressure ring 12 can be well compatible with the original assembly logic of the high-voltage electrical components and does not affect the functional synergy of other components.

[0045] like Figure 2 As shown, in one embodiment, the fastener 3 includes a threaded locking sleeve 31 and an elastic pressure rod 32 located inside it. The threaded locking sleeve 31 is disposed outside the housing 1 and achieves axial movement through a threaded connection with the housing 1, thereby adjusting the applied force. The elastic pressure rod 32 is installed inside the threaded locking sleeve 31 and is disposed opposite to the upper surface of the seal 2. When the fastener 3 is further tightened, the elastic pressure rod 32 is subjected to compressive force, gradually moves towards the seal 2, and transmits pressure to the seal 2.

[0046] Specifically, the elastic pressure rod 32 is made of a high-pressure resistant material with high elastic recovery characteristics, capable of providing a continuously increasing pressure output within a certain range to compensate for preload loss caused by changes in ambient temperature or prolonged use. Simultaneously, its combination with the threaded locking sleeve 31 allows for a more even distribution of force on the seal 2, ensuring more reliable sealing performance of the high-voltage electrical components. For example, by increasing the tightening degree of the threaded locking sleeve 31, the elastic pressure rod 32 can be further compressed, ultimately achieving the technical requirement of enhanced preload effect of the seal 2.

[0047] like Figure 5 As shown, in one embodiment, the fastener 3 of a high-voltage electrical component of this application is provided with an adjusting knob 33 at its tail. This component is located at the end of the fastener 3, allowing the operator to manually rotate it to apply precise torque. The adjusting knob 33 is connected to the fastener 3 through a specific structure and can flexibly adjust the magnitude of the tightening force, thereby changing the force exerted on the seal 2. By controlling the rotation amplitude of the adjusting knob 33, the seal 2 can be stably tightened or finely loosened under different operating conditions to adapt to the changing needs of actual application scenarios.

[0048] Furthermore, the adjustment knob 33 adopts a polygonal or graduated design to ensure that the range of force adjustment can be intuitively observed during rotation. This connection method ensures both ease of operation and meets the requirements for sealing reliability. In addition, the adjustment knob 33 is usually equipped with a transmission mechanism inside, so that external force is transmitted to the fastener 3 through threads or other means to achieve precise force distribution.

[0049] For example, a force-distributing device, such as an elastic washer or a progressive thread assembly, can be designed between the adjusting knob 33 and the fastener 3. When torque is applied, the force-distributing device will gradually distribute the preload to the surface of the seal 2, keeping its deformation within a reasonable range to ensure the long-term operational stability of the entire system. Specifically, the adjustment process is optimized by selecting appropriate pitch and friction parameters according to the actual assembly accuracy requirements.

[0050] like Figure 2 As shown, in one embodiment, an auxiliary pressure ring 41 is disposed outside the support frame 4 of a high-voltage electrical component according to this application. The auxiliary pressure ring 41 surrounds the periphery of the support frame 4 and, through its cooperation with the housing 1, forms an effective pressure structure for the lower sealing element 2. Specifically, after the auxiliary pressure ring 41 is assembled with the support frame 4, it is positioned close to the sealing element 2 and in close contact with the inner surface of the housing 1. Its function is to further improve the sealing reliability by adjusting the assembly gap, ensuring that the entire high-voltage electrical component can adapt to complex working environments.

[0051] The auxiliary pressure ring 41 is a circular part, which can be made of metal or high-strength composite material, and has certain elastic or pre-stress characteristics. It may have a direct mechanical limiting relationship with the housing 1. This design allows for more uniform pressure transmission to the seal 2 during the tightening of the fastener 3. Simultaneously, due to the intervention of the auxiliary pressure ring 41, even if the housing 1 has manufacturing tolerances or assembly deformation, an ideal sealing effect can be maintained through a compensation mechanism.

[0052] For example, the support frame 4 can be first assembled into the designated position within the cavity of the housing 1, ensuring a secure connection. Then, the prefabricated auxiliary pressure ring 41 is fitted onto the outside of the support frame 4, aligning its central axis with the center of the support frame 4. Finally, the overall assembly with the remaining components of the housing 1 is completed. Based on this, the bonding force between the housing 1 and the fasteners 3 can be further adjusted by design to compact the critical sealing points located in the areas of the seal 2 and the auxiliary pressure ring 41.

[0053] like Figure 2As shown, in one embodiment, a buffer rubber pad 42 is provided at the bottom of the support frame 4 of a high-voltage electrical component according to this application. The buffer rubber pad 42 is installed at the end of the support frame 4 facing the inner wall of the housing 1, and its main function is to reduce the impact of external vibration on the overall device. Specifically, high-voltage electrical equipment may experience loosening between structural components due to external vibration or internal current surges during operation, and the stability of the preload is crucial to ensuring the normal operation of high-voltage components. By adding a flexible buffer material between the support frame 4 and the housing 1, the vibration resistance can be significantly improved without affecting the original connection relationship. Furthermore, the buffer rubber pad 42 itself is composed of a multi-layer structure, including an outer covering layer and an inner reinforcing core, thereby further meeting the reliability and durability requirements for use in high-voltage environments.

[0054] For example, in actual assembly, the buffer rubber pad 42 can be fixed to the bottom surface of the support frame 4 using an adhesive process, while retaining a certain thickness allowance to adapt to stress distribution changes under different scenarios. This ensures structural stability while avoiding excessive wear caused by long-term use. Therefore, the above features represent an effective improvement in the technical solution and expand its applicability.

[0055] like Figure 2 As shown, in one embodiment, the conductive contact 5 of a high-voltage electrical component of this application is fixedly connected to the housing 1 via an insulating mounting sleeve 51. The housing 1 has a specific location for mounting the conductive contact 5, and the insulating mounting sleeve 51 isolates the conductive contact 5 from the housing 1. The insulating mounting sleeve 51 is made of a high-voltage resistant and high-temperature resistant material, which can effectively prevent short circuits or other adverse electrical phenomena caused by high-voltage current between the conductive contact 5 and the housing 1. Furthermore, the insulating mounting sleeve 51 is designed to have good mechanical strength and electrical insulation properties, ensuring that the conductive contact 5 is securely mounted on the housing 1 and can withstand vibrations or impacts that may occur during operation.

[0056] To ensure reliable connection, the conductive contact 5 and the insulating mounting sleeve 51 are tightly fitted together, and the insulating mounting sleeve 51 is embedded in a predetermined position on the housing 1. The mounting position on the housing 1 is usually precisely machined to match the shape of the insulating mounting sleeve 51, thereby achieving stable fixation between the two. In addition, the outer structure of the insulating mounting sleeve 51 matches the design of the housing 1, which can prevent misalignment or loosening during assembly.

[0057] For example, an insulating mounting sleeve 51 made of epoxy resin can be selected and fixed to a special hole on the housing 1 by interference fit or threaded connection. The conductive contact 5 is then embedded inside the insulating mounting sleeve 51 and its position is further locked by welding or fasteners 3, thereby completing a firm assembly relationship between the three.

[0058] like Figure 2 As shown, in one embodiment, the conductive contact 5 of a high-voltage electrical component of this application is externally coated with a waterproof coating 52, extending to cover a position close to the housing 1. This waterproof coating 52 adheres tightly to the surface of the conductive contact 5, forming a continuous protective layer. Through this structural design, the conductive contact 5 can not only effectively prevent external moisture intrusion but also work in conjunction with the seal 2 to reduce the risk of chamber leakage. Specifically, the edge transition area of ​​the waterproof coating 52 undergoes special processing to ensure a smoother and more stable bond between it and the adjacent housing 1, thereby avoiding potential defects caused by irregular boundaries.

[0059] For example, the waterproof coating 52 can be applied to the surface of the conductive contact 5 by coating or thermal deposition. To achieve its effect of extending to the adjacent housing 1, a material with a certain degree of flexibility can be used, and the coating range can be precisely controlled during construction to ensure complete coverage without obvious breaks. At the same time, this process needs to consider the consistency of the coating thickness to avoid interfering with the overall assembly accuracy of the housing 1. Thus, the coating and the seal 2 together constitute a multi-layered protective barrier, optimizing the overall waterproof performance of the component.

[0060] In actual operation, when this device is in use, the housing 1 of the high-voltage electrical components houses the high-voltage electrical components, and the corrugated structure 21 of the seal enhances its flexibility and deformation capability to effectively adapt to different installation conditions. Simultaneously, the raised pre-tightening ring 22 on the seal 2 increases the friction between it and the housing 1, while the radial adjustment groove 23 allows for adjustment of the pre-tightening force according to actual needs, thus ensuring no leakage occurs in high-humidity environments. Fasteners 3 tighten the seal 2 via threaded connections, further improving sealing performance. The support frame 4 is fixed inside the housing 1, providing necessary structural support for the high-voltage electrical components to ensure operational stability. Conductive contacts 5 are mounted on the housing 1 and connected to the external circuit for transmitting high-voltage current. When the equipment is started, all components work together to ensure the safety and reliability of the high-voltage electrical components in complex environments.
