Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to an electrical connector. Background Technology

[0002] In modern equipment stacking applications, especially in the stacking of battery packs and power conversion systems (PCS) in home energy storage products, connectors are usually required on the top and bottom surfaces of the equipment to enable quick and convenient connection between the devices.

[0003] Existing connector designs can be broadly categorized into floating connectors and fixed connectors. However, existing technologies present several problems in practical applications. First, when using floating connectors to accommodate stacked assembly tolerances, a gap exists between the connector and the panel, which compromises waterproofing performance. This is particularly problematic in non-professional home installation scenarios, where device disassembly and installation are flexible, increasing the risk of water ingress. Water ingress could lead to electrical short circuits or even fires.

[0004] To avoid waterproofing issues with floating connectors, other solutions employ fixed connectors and utilize elastic sealing materials for sealing. While this design provides good waterproofing, it has drawbacks such as misalignment of the device's appearance, and the guide structure is susceptible to excessive stress during assembly, potentially leading to damage or deformation.

[0005] Another approach involves not fully compressing the fixed connector, similar to traditional connectors. During use, the connector is not fully pressed against the panel, allowing it to move and utilizing the compression of the sealing ring to achieve a certain level of waterproofing. However, this approach struggles to meet high waterproofing requirements while maintaining the floating function, especially in mass production where the probability of waterproofing failure is relatively high, making it unsuitable for scenarios with high reliability requirements.

[0006] While existing technologies offer various methods for achieving the connection and sealing functions of stacked connectors, all designs—whether floating, fixed, or with a non-clamped fixed connector—have limitations in waterproofing, assembly tolerances, and reliability. Therefore, providing excellent waterproofing while ensuring the floating function of the connector has become a pressing technical challenge. Utility Model Content

[0007] In order to provide an electrical connector structure that provides an effective waterproof seal while satisfying the floating function of the device connector, this application provides an electrical connector.

[0008] The electrical connector provided in this application adopts the following technical solution:

[0009] An electrical connector, comprising:

[0010] Electrical connection components used to achieve electrical connections;

[0011] A panel mounting assembly for floatingly mounting the electrical connection assembly on a device panel;

[0012] A sealing assembly dynamically seals with the electrical connection assembly, the device panel, and the panel fixing assembly to prevent external substances from entering the electrical connection area; and the sealing assembly allows the electrical connection assembly to float.

[0013] By adopting the above technical solution, and combining the floating design of the electrical connection components with the dynamic sealing characteristics of the sealing components, a waterproof sealing function is achieved. The floating installation function improves the fault tolerance of the electrical connection assembly, enabling the electrical connection assembly to adapt to deformation or vibration changes in different working environments, thereby maintaining a stable electrical connection and avoiding poor contact caused by panel displacement or external vibration. The sealing component, through elastic deformation, automatically adjusts the sealing state while the electrical connection assembly floats, effectively preventing external substances from penetrating into the electrical connection area and maintaining reliable waterproof sealing performance. In addition, this design not only improves the adaptability and versatility of the electrical connector in complex environments, but also enhances the long-term reliability of the equipment, reduces the probability of failure, extends the service life of the equipment, reduces maintenance costs, and greatly improves overall stability and durability.

[0014] In one specific implementation, the panel fixing assembly includes a panel fixing plate located between the electrical connection assembly and the device panel. The panel fixing plate is fitted onto the electrical connection assembly and fixed to the device panel.

[0015] By adopting the above technical solution, the electrical connection components can not only maintain flexible floating to adapt to environmental changes through the support of the panel fixing plate, but also avoid problems such as poor electrical contact caused by excessive floating; at the same time, it ensures that the electrical connection components can float within a certain range to adapt to the deformation or vibration of the equipment panel in different working environments.

[0016] In one specific implementation, the sealing assembly includes a first sealing gasket disposed between the panel fixing plate and the device panel, and pressed onto the device panel by the panel fixing plate; the first sealing gasket extends along the panel fixing plate to the electrical connection assembly, and is pressed onto the electrical connection assembly by a sealing gasket pressure plate.

[0017] By adopting the above technical solution, a multi-layer protective structure is formed by combining the sealing gasket and the sealing gasket pressure plate. On the one hand, the sealing gasket pressure plate can form a seal with the electrical connection components, and on the other hand, the panel fixing plate can form a seal with the equipment panel, thus achieving sealed protection for the electrical connection area. This structure not only effectively blocks interference from the external environment and prevents the intrusion of external substances such as water and dust, but also enhances the long-term stability and reliability of the equipment, thereby improving the equipment's protection capabilities, reducing the risk of failure, and extending its service life.

[0018] In one specific implementation, the electrical connection assembly is provided with a pre-embedded screw, which passes through the panel fixing plate, the first sealing gasket, and the sealing gasket pressure plate in sequence. The pre-embedded screw passes through the sealing gasket pressure plate and is threaded with a nut. The nut presses the first sealing gasket onto the electrical connection assembly through the sealing gasket pressure plate.

[0019] By adopting the above technical solution, the sealing gasket forms a sealing structure with the electrical connection components through the tightening action of the nut, effectively preventing the ingress of water, dust and other external substances, and improving the protection capability of the equipment; at the same time, the combination of pre-embedded screws and nuts makes the sealing structure stable and reliable, avoiding sealing failure caused by vibration or external force, ensuring overall long-term stability and improving service life.

[0020] In one specific implementation, the first sealing gasket is provided with floating corrugations that protrude toward one side of the device panel to reduce the elastic deformation of the first sealing gasket when the electrical connection assembly floats.

[0021] By adopting the above technical solution, the floating corrugation design provides additional elastic adjustment space, allowing the first sealing gasket to deform appropriately with the floating of the electrical connection components, thereby reducing elastic fatigue or permanent deformation caused by floating or vibration, maintaining sealing performance, extending service life, and improving its long-term reliability and protective effect.

[0022] In one specific implementation, the sealing assembly includes:

[0023] The second sealing gasket is disposed between the panel fixing plate and the equipment panel, and is pressed onto the equipment panel by the panel fixing plate;

[0024] A sealing ring is disposed between the panel fixing plate and the electrical connection assembly.

[0025] By adopting the above technical solution, the combination of the second sealing gasket and the sealing ring provides double protection. The second sealing gasket forms a tight seal between the panel fixing plate and the equipment panel, and the sealing ring forms a tight seal between the panel fixing plate and the electrical connection components. By designing sealing components in different parts, the overall sealing performance of the equipment is further enhanced, preventing external substances from entering the electrical connection area, reducing the risk of damage to the electrical connection parts, and ensuring its stable operation in long-term use.

[0026] In one specific implementation, the sealing ring is provided with a sealing structure and abuts and seals against the electrical connection assembly and the panel fixing plate through the sealing structure. The sealing structure includes one or more of radial sealing structures, axial sealing structures, and corner sealing structures.

[0027] By adopting the above technical solutions, the design of the sealing structure ensures that the sealing ring can make close contact with the electrical connection components during the assembly process. Through various sealing methods such as radial sealing structure, transverse sealing structure, and corner sealing structure, it achieves interference fit with the panel fixing plate and electrical connection components, forming a multi-seal mechanism and comprehensively enhancing the sealing effect.

[0028] In one specific implementation, a limiting structure is also included, extending from the panel fixing plate toward the electrical connection assembly, for limiting the floating range of the electrical connection assembly.

[0029] In one specific implementation, the limiting structure includes a limiting post disposed on the panel fixing plate. The limiting post extends from the panel fixing plate toward the electrical connection assembly and is connected to the limiting plate. A horizontal floating gap is formed between the limiting post and the electrical connection assembly, and a vertical floating gap is formed between the limiting plate and the electrical connection assembly.

[0030] By adopting the above technical solution, the horizontal floating gap between the limiting post and the electrical connection component, and the vertical floating gap between the limiting plate and the electrical connection component, can provide the electrical connection component with free floating space in three dimensions. This makes the electrical connection component more fault-tolerant in the subsequent electrical connection process. Even if there are errors or offsets, they can be automatically adjusted through the floating gap, ensuring the ease and reliability of installation and enhancing the adaptability of the electrical connector to various uncertain factors.

[0031] In one specific implementation, the electrical connection assembly includes at least one pair of interconnected electrical connection modules, each of which is correspondingly provided with the panel fixing assembly and the sealing assembly.

[0032] In summary, the beneficial technical effects of this application are as follows: The electrical connector of this application, through innovative design, combines the floating function of the electrical connection component and the dynamic sealing characteristics of the sealing component to provide an effective waterproof sealing solution; the design of the panel fixing component enables the floating installation of the electrical connection component, which can adapt to changes in both horizontal and vertical directions, improves the fault tolerance of the electrical connection component mating, ensures stable electrical contact, avoids poor contact in traditional connectors, and thus prevents electrical connection problems caused by external forces or vibrations;

[0033] Meanwhile, the design of the sealing component effectively prevents external substances such as water and dust from entering the electrical connection components, thus maintaining the connector's good working condition. Furthermore, the sealing component can automatically adjust its sealing state through elastic deformation as the electrical connection components float, effectively preventing external substances from seeping into the electrical connection area and maintaining reliable waterproof sealing performance. In addition, this design not only improves the adaptability and versatility of the electrical connector in complex environments, but also enhances the long-term reliability of the equipment, reduces the probability of failure, extends the service life of the equipment, reduces maintenance costs, and greatly improves overall stability and durability.

[0047] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0048] Example 1

[0049] Reference Figure 1 and Figure 2 This application discloses an electrical connector, comprising:

[0050] Electrical connection assembly 1 includes at least one pair of mutually compatible and electrically connected connection modules. In this embodiment, electrical connection assembly 1 includes a pair of mutually compatible and electrically connected connection modules. Each connection module includes a male base 11 and a female base 12. The male base 11 is provided with a male terminal 111, and the female base 12 is provided with a female terminal 121. When the connection modules are connected, the male base 11 and the female base 12 are plugged into each other, and the electrical connection is achieved through the plugging and connecting of the male terminal 111 and the female terminal 121.

[0051] In this embodiment, waterproof sealing is achieved between the male base 11 and the male terminal 111, and between the female base 12 and the female terminal 121, including but not limited to using potting compound to prevent moisture from entering the connection area and improve the durability of the electrical connector.

[0052] In this embodiment, each connection module is provided with a panel fixing component 2 and a sealing component 3, that is, the male end base 11 and the female end base 12 are respectively provided with a panel fixing component 2 and a sealing component 3:

[0053] In this embodiment, both the male base 11 and the female base 12 can be floatingly mounted on the device panel 5 via the panel fixing assembly 2. In other embodiments, only the male base 11 or the female base 12 can be designed to be floatingly mounted. Through the floating mounting design, the insertion fault tolerance of the male base 11 and the female base 12 and the insertion fault tolerance of the male terminal 111 and the female terminal 121 can be improved when the connection modules are connected in the future. In actual use, it can avoid poor connection or damage caused by thermal expansion, mechanical vibration and other factors.

[0054] In this embodiment, the sealing component 3 dynamically seals with the electrical connection component 1, the device panel 5, and the panel fixing component 2 to prevent external substances from entering the electrical connection area, thereby achieving a waterproof function. In this embodiment, the sealing component 3 can allow the male end base 11 or the female end base 12 to float in three dimensions through elastic deformation.

[0055] In actual use, the male base 11 and female base 12 are first floatably mounted on the corresponding equipment panel 5 by the panel fixing component 2. At this time, the sealing component 3 forms a dynamic seal between the male base 11, the equipment panel 5 and the panel fixing component 2 to prevent external substances such as liquids and dust from entering the electrical connection area. The sealing component 3 can adapt to the floating of the male base 11 or the female base 12 by elastic deformation, allowing the male base 11 or the female base 12 to float in three dimensions. When the connection module is docked, the male base 11 and the female base 12 are plugged in and docked, and the electrical connection is achieved by plugging in the male terminal 111 and the female terminal 121 to ensure the docking and transmission of electrical signals.

[0056] Reference Figure 3 and Figure 4 The panel fixing assembly 2 includes a panel fixing plate 21, which is fitted onto the electrical connection assembly 1 (male base 11 or female base 12) and fixed to the device panel 5. The panel fixing plate 21 is located between the electrical connection assembly 1 and the device panel 5. In this embodiment, part of the structure of the electrical connection assembly 1 (male base 11 or female base 12) passes through the panel fixing plate 21.

[0057] It also includes a limiting structure 22, which is used to limit the floating range of the electrical connection assembly 1. In this embodiment, the limiting structure 22 includes, but is not limited to, a limiting post 221 provided on the panel fixing plate 21. The limiting post 221 extends from the panel fixing plate 21 toward the electrical connection assembly 1 (male end base 11 or female end base 12). A limiting plate 222 is connected to the side of the limiting post 221 away from the panel fixing plate 21. The limiting plate 222 is located on the side of the electrical connection assembly 1 (male end base 11 or female end base 12) away from the panel fixing plate 21.

[0058] A horizontal floating gap 6 is formed between the limiting post 221 and the electrical connection assembly 1 (male end base 11 or female end base 12), and a vertical floating gap 6 is formed between the limiting plate 222 and the electrical connection assembly 1 (male end base 11 or female end base 12), thereby allowing the electrical connection assembly 1 to float in three dimensions. The limiting post 221 and the limiting plate 222 can achieve floating limitation of the electrical connection assembly 1 (male end base 11 or female end base 12) by abutting against the outer wall of the electrical connection assembly 1 (male end base 11 or female end base 12).

[0059] In this embodiment, the panel fixing plate 21 is fixed to the device panel 5 by fixing screws 4. When fixing the panel fixing plate 21, the fixing screws 4 are passed through the holes of the limiting post 221, the panel fixing plate 21 and the device panel 5 in sequence, and the fixing screws 4 are threaded to the device panel 5. The nuts of the fixing screws 4 are tightened and abut against the limiting post 221. The threaded connection ensures the fixation between the device panel 5 and the panel fixing plate 21. In this embodiment, a washer 41 is provided between the nuts of the fixing screws 4 and the limiting post 221. The nuts of the fixing screws 4 are abutted against the limiting post 221 by the washer 41.

[0060] In this process, the panel fixing plate 21 serves to fix the electrical connection assembly 1 to the equipment panel 5. At the same time, through the design of the limiting structure 22, it ensures that the electrical connection assembly 1 (male base 11 or female base 12) can float within a certain range. Even if there are errors or offsets, they can be automatically adjusted through the floating gap 6, thereby facilitating smooth docking of the male base 11 and the female base 12, improving fault tolerance, and ensuring ease and reliability of installation. Furthermore, the limiting post 221 and the limiting plate 222 can limit the floating range of the electrical connection assembly 1, avoid poor contact or damage caused by excessive floating, enhance the adaptability of the electrical connector to various uncertain factors, reduce the risk of failure, and extend the service life.

[0061] In other embodiments, the limiting structure 22 can also be configured as other structures that can limit the floating of the electrical connection component 1, such as: an elastic limiting structure, which provides elastic buckles on the panel fixing plate 21 to provide floating space and limit the displacement range through elastic deformation; or a multi-level limiting structure, which adopts a multi-level step or protrusion design to provide limiting functions in different directions.

[0062] Reference Figure 2 and Figure 3 In this embodiment, the sealing assembly 3 includes a first sealing gasket 31, which is disposed between the panel fixing plate 21 and the device panel 5 and is pressed onto the device panel 5 by the panel fixing plate 21 to ensure the sealing effect between the first sealing gasket 31 and the device panel 5; the first sealing gasket 31 extends inward along the panel fixing plate 21 to the electrical connection assembly 1 (male end base 11 or female end base 12);

[0063] In this embodiment, the first sealing gasket 31 is pressed against the electrical connection assembly 1 (male base 11 or female base 12) by the sealing gasket pressure plate 32. The sealing gasket pressure plate 32 is located on the side of the first sealing gasket 31 away from the panel fixing plate 21. The electrical connection assembly 1 (male base 11 or female base 12) is provided with a pre-embedded screw 13. The pre-embedded screw 13 passes through the panel fixing plate 21, the first sealing gasket 31, and the sealing gasket pressure plate 32 in sequence. The pre-embedded screw 13 passes through the sealing gasket pressure plate 32 and is threadedly connected to the nut 331. By tightening the nut 331, the sealing gasket pressure plate 32 is pressed, thereby tightly fitting the first sealing gasket 31 against the electrical connection assembly 1 (male base 11 or female base 12) through the sealing gasket pressure plate 32, ensuring the sealing effect between the first sealing gasket 31 and the electrical connection assembly 1 (male base 11 or female base 12).

[0064] The first sealing gasket 31 is provided with floating corrugations 311, which protrude toward one side of the equipment panel 5. The design of the floating corrugations 311 can provide additional elastic adjustment space, so that the first sealing gasket 31 can be moderately deformed as the electrical connection assembly 1 (male end base 11 or female end base 12) floats, thereby reducing elastic fatigue or permanent deformation caused by floating or vibration, maintaining sealing performance, extending service life, and improving its long-term reliability and protection effect.

[0065] In other embodiments, the first sealing gasket 31 may also be fixed to the electrical connection assembly 1 (male base 11 or female base 12) using other structures, including but not limited to using liquid silicone injection molding to bond the first sealing gasket 31 to the electrical connection assembly 1 (male base 11 or female base 12), or using a snap-fit ​​structure to press the sealing gasket onto the electrical connection assembly 1 (male base 11 or female base 12).

[0066] In this embodiment, the sealing component 3 is set as the first sealing gasket 31 and pressed onto the electrical connection component 1 by the sealing gasket pressure plate 32. This design is applicable to the sealing of the electrical connection component 1, which requires a large range of floating. When the electrical connection component 1 floats a large range, since the sealing gasket pressure plate 32 always presses the first sealing gasket 31 onto the electrical connection component 1, it can ensure that the electrical connection component 1 always maintains a good sealing state while achieving floating.

[0067] The implementation principle of this application embodiment is as follows: During installation, the panel fixing plate 21 is first fitted onto the electrical connection component 1 (male end base 11 or female end base 12). At this time, the limiting post 221 will extend toward the electrical connection component 1 (male end base 11 or female end base 12), and the limiting plate 222 is fitted onto the limiting post 221.

[0068] Place the first sealing gasket 31 on the panel fixing plate 21 and ensure that the installation position of the first sealing gasket 31 is correct. Then use fixing screws 4 to fix the panel fixing plate 21, the electrical connection assembly 1, and the first sealing gasket 31. Specifically, pass the fixing screws 4 through the holes on the limiting post 221, the panel fixing plate 21, and the equipment panel 5 in sequence, and thread the fixing screws 4 to the equipment panel 5. The nuts of the fixing screws 4 are tightened and abut against the limiting post 221. At this time, the limiting plate 222 and the limiting post 221 will form a limiting and fixing effect on the electrical connection assembly 1 (male end base 11 or female end base 12). At the same time, the panel fixing plate 21 will press the first sealing gasket 31 onto the equipment panel 5 to form a seal between it and the equipment panel 5.

[0069] During this process, the pre-embedded screws 13 on the electrical connection assembly 1 (male base 11 or female base 12) will pass through the panel fixing plate 21, the first sealing gasket 31 and out of the first sealing gasket 31 in sequence. Then, the sealing gasket pressure plate 32 is put on the pre-embedded screws 13 and the nut 331 is threadedly connected to the pre-embedded screws 13. The nut 331 presses the sealing gasket pressure plate 32 on the first sealing gasket 31 to form a seal between the electrical connection assembly 1 (male base 11 or female base 12).

[0070] After the entire installation is completed, the electrical connection component 1 can be electrically connected. Specifically, the male base 11 and the female base 12 are plugged in and connected, and the electrical connection is achieved by plugging in the male terminal 111 and the female terminal 121 to ensure the connection and transmission of electrical signals. During this process, the panel fixing plate 21 and the limiting structure 22 can ensure that the male base 11 and the female base 12 can float in three dimensions, thereby improving the fault tolerance of the plugging and avoiding poor contact caused by errors or offsets. At the same time, the sealing component 3 can ensure the sealing effect while the electrical connection component 1 floats through elastic deformation.

[0071] The electrical connector of this application, through innovative design, combines panel fixing component 2, sealing component 3 and floating installation structure, which can improve waterproof sealing effect while ensuring the stability and reliability of the electrical connector; through the floating installation of male end base 11 and female end base 12, it solves the connection problems caused by factors such as slight deviation of equipment panel 5, thermal expansion, mechanical vibration, etc., thereby enhancing the plugging tolerance of electrical connection component 1.

[0072] The sealing component 3, through its dynamic sealing function, prevents external substances such as liquids and dust from entering the electrical connection area, ensuring the overall waterproof performance of the electrical connector. Furthermore, the floating corrugation 311 design of the sealing gasket adapts to elastic changes in accordance with the floating of the electrical connection component 1, reducing elastic fatigue or permanent deformation caused by floating or vibration, and extending the durability of the sealing effect. In addition, the design of the panel fixing plate 21 and the limiting structure 22 not only ensures reliable fixation of the connection module but also provides tolerance space, allowing the connection module to float freely in three dimensions. Even with errors or displacement of the device panel 5, it can automatically adjust, ensuring smooth connector docking and enhancing the ease and reliability of installation. These designs extend service life and optimize the installation process, ensuring stable operation in various dynamically changing working environments.

[0073] Example 2

[0074] Reference Figure 5-8 The difference between this embodiment and the first embodiment is that the sealing component 3 includes a second sealing gasket 34 and a sealing ring 35. The second sealing gasket 34 is disposed between the panel fixing plate 21 and the equipment panel 5, and is pressed onto the equipment panel 5 by the panel fixing plate 21 to form a seal between the sealing component and the equipment panel 5.

[0075] A sealing ring 35 is disposed between the panel fixing plate 21 and the electrical connection assembly 1 (male end base 11 or female end base 12) for sealing between the panel fixing plate 21 and the electrical connection assembly 1 (male end base 11 or female end base 12).

[0076] The sealing ring 35 is provided with a sealing structure 351, and the sealing structure 351 abuts and seals with the electrical connection assembly 1 (male end base 11 or female end base 12) and the panel fixing plate 21.

[0077] The sealing structure 351 includes one or more of the following: radial sealing structure 3511, axial sealing structure 3512, and corner sealing structure 3513. In this embodiment, the design type and quantity of the sealing structure 351 are selected and designed according to the actual waterproofing requirements.

[0078] The sealing structure 351 on the sealing ring 35 in this embodiment includes: a radial sealing structure 3511 on the inner and outer sides, an axial sealing structure 3512 on one side, and a corner sealing structure 3513 on the two corners. In this embodiment, the sealing ring 35 is fitted on the panel fixing plate 21. The sealing ring 35 forms abutment seal in multiple directions through the radial sealing structure 3511, the axial sealing structure 3512, the corner sealing structure 3513 and the electrical connection assembly 1 (male end base 11 or female end base 12). The radial seal ensures the sealing performance in the circumferential direction, the axial seal ensures the sealing performance in the axial direction, and the corner seal provides additional protection in corners, seams and complex areas.

[0079] This multi-layered and multi-directional sealing design comprehensively enhances the sealing effect, preventing external contaminants from entering the electrical connection area, improving overall reliability, extending equipment lifespan, and enhancing the equipment's stability and adaptability in complex working environments.

[0080] In this embodiment, the sealing component 3 is set as a combination of the second sealing gasket 34 and the sealing ring 35, which respectively form a seal between the equipment panel 5 and the panel fixing plate 21 and a seal between the panel fixing plate 21 and the electrical connection component 1. Compared with the first embodiment, this design is suitable for sealing the electrical connection component 1, which requires a small range of floating, and can ensure that the electrical connection component 1 maintains a good sealing state while achieving a small range of floating.

[0081] In actual use, the sealing ring 35 is fitted onto the panel fixing plate 21, and then the panel fixing plate 21 is fitted onto the electrical connection assembly 1 (male end base 11 or female end base 12). At this time, the sealing ring 35 forms abutment seal in multiple directions through the radial sealing structure 3511, axial sealing structure 3512, corner sealing structure 3513 on it and the electrical connection assembly 1 (male end base 11 or female end base 12).

[0082] Next, place the second sealing gasket 34 on the panel fixing plate 21 and ensure that the installation position of the second sealing gasket 34 is correct. Then, use the fixing screw 4 to pass through the holes on the limiting post 221, the panel fixing plate 21, and the equipment panel 5 in sequence, and thread the fixing screw 4 to the equipment panel 5. The nut of the fixing screw 4 is tightened and abuts against the limiting post 221. At this time, the limiting plate 222 and the limiting post 221 will form a limiting and fixing effect on the electrical connection assembly 1 (male end base 11 or female end base 12). At the same time, the panel fixing plate 21 will press the second sealing gasket 34 tightly on the equipment panel 5 to form a seal between it and the equipment panel 5.

[0083] This embodiment provides double sealing protection by combining the second sealing gasket 34 and the sealing ring 35, effectively improving the sealing performance of the equipment; the second sealing gasket 34 is located between the panel fixing plate 21 and the equipment panel 5, and through the pressing action of the panel fixing plate 21, a tight seal is formed between the equipment panel 5 and the panel fixing plate 21.

[0084] The sealing ring 35, through the design of the sealing structure 351, forms a seal in multiple directions using the radial sealing structure 3511, the axial sealing structure 3512, and the corner sealing structure 3513. The radial seal ensures the sealing performance in the circumferential direction, the axial seal ensures the sealing performance in the axial direction, and the corner seal provides additional protection in corners, joints, and complex areas, thereby effectively preventing external substances from entering the electrical connection area, enhancing the sealing effect, and improving the overall stability and reliability.

[0085] Example 3

[0086] Reference Figure 9 The difference between this embodiment and embodiment two is that the sealing ring 35 and the second sealing gasket 34 are connected as an integral structure. In this embodiment, the sealing ring 35 extends along the inner wall of the panel fixing plate 21 to the second sealing gasket 34 and connects with the second sealing gasket 34 to form an integral structure.

[0087] Specifically, the second sealing gasket 34 is disposed between the panel fixing plate 21 and the equipment panel 5; the sealing ring 35 is disposed between the panel fixing plate 21 and the electrical connection assembly 1 (male end base 11 or female end base 12). The sealing ring 35 extends along the inner wall of the panel fixing plate 21 toward the equipment panel 5 and extends to the second sealing gasket 34 to connect with the second sealing gasket 34, forming an integral structure. In this embodiment, the sealing ring 35 and the second sealing gasket 34 include, but are not limited to, being connected by adhesive or integrally formed.

[0088] This embodiment, by connecting the sealing ring 35 and the second sealing gasket 34 to form an integrated structure, can ensure the stability and durability of the sealing component 3. The structure of the sealing component 3 is more simplified, and it can reduce the potential risk of interface leakage between the sealing ring 35 and the second sealing gasket 34, ensuring efficient operation and equipment stability during long-term use, and improving the sealing effect.

[0089] Example 4

[0090] Reference Figure 10The difference between this embodiment and embodiment two is that the sealing structure 351 of the sealing ring 35 is set as a separate radial sealing structure 3511; in this embodiment, the sealing ring 35 is fitted on the electrical connection assembly 1 (male end base 11 or female end base 12), and the sealing ring 35 forms a radial seal (circumferential abutment seal) through the radial sealing structure 3511 on it and the panel fixing plate 21.

[0091] In actual use, the sealing ring 35 is first installed on the outer wall of the electrical connection assembly 1 (male base 11 or female base 12) to form a seal with the electrical connection assembly 1. Then, the panel fixing plate 21 is fitted onto the electrical connection assembly 1 (male base 11 or female base 12). During this process, the inner wall of the panel fixing plate 21 comes into contact with the sealing ring 35 that has been installed on the outer wall of the electrical connection assembly 1. The sealing ring 35 abuts against the panel fixing plate 21 through the radial sealing structure 3511 to seal.

[0092] Next, place the second sealing gasket 34 on the panel fixing plate 21 and ensure that the installation position of the second sealing gasket 34 is correct. Then, use the fixing screw 4 to pass through the holes on the limiting post 221, the panel fixing plate 21, and the equipment panel 5 in sequence, and thread the fixing screw 4 to the equipment panel 5. The nut of the fixing screw 4 is tightened and abuts against the limiting post 221. At this time, the limiting plate 222 and the limiting post 221 will form a limiting and fixing effect on the electrical connection assembly 1 (male end base 11 or female end base 12). At the same time, the panel fixing plate 21 will press the second sealing gasket 34 tightly on the equipment panel 5 to form a seal between it and the equipment panel 5.

[0093] This embodiment provides double sealing protection by combining the second sealing gasket 34 and the sealing ring 35, effectively improving the sealing performance of the equipment. The second sealing gasket 34 is located between the panel fixing plate 21 and the equipment panel 5. Through the pressing action of the panel fixing plate 21, a tight seal is formed between the equipment panel 5 and the panel fixing plate 21. The sealing ring 35 forms a radial seal between the electrical connection assembly 1 (male end base 11 or female end base 12) and the panel fixing plate 21 through the radial sealing structure 3511. This ensures that the sealing performance remains stable under high pressure or vibration working environment, preventing external substances from entering the electrical connection area.

[0094] This sealing design enhances the overall sealing of the equipment, reduces the risk of damage to electrical connections, and ensures stable operation of the equipment during long-term use. In addition, the design reduces the maintenance requirements of the equipment, can adapt to complex environments, and extends the service life of the equipment, thereby enhancing overall reliability and stability.

[0095] Example 5

[0096] Reference Figure 11The difference between this embodiment and embodiment two is that the sealing structure 351 of the sealing ring 35 is set as a separate axial sealing structure 3512; the axial sealing structure 3512 forms an axial seal between the panel fixing plate 21 and the electrical connection assembly 1 (male end base 11 or female end base 12);

[0097] In this embodiment, the electrical connection assembly 1 (male base 11 or female base 12) and the panel fixing plate 21 together form a receiving groove 7 on the opposite side. The sealing ring 35 is embedded in the receiving groove 7, and an axial seal is formed between the panel fixing plate 21 and the electrical connection assembly 1 (male base 11 or female base 12) through the axial sealing structure 3512.

[0098] Example 6

[0099] Reference Figure 12 The difference between this embodiment and embodiment two is that the sealing structure 351 of the sealing ring 35 is set as a separate corner sealing structure 3513. In this embodiment, the sealing ring 35 is fitted on the corner of the panel fixing plate 21, and forms an abutment seal with the corner position of the electrical connection component 1 (male end base 11 or female end base 12) through the corner sealing structure 3513, thereby achieving the sealing between the panel fixing plate 21 and the electrical connection component 1 (male end base 11 or female end base 12).

[0100] Example 7

[0101] The difference between this embodiment and Embodiment 2 is that the sealing structure 351 of the sealing ring 35 can be designed as a combination of radial sealing structure 3511, axial sealing structure 3512, and corner sealing structure 3513. Furthermore, the number of radial sealing structure 3511, axial sealing structure 3512, and corner sealing structure 3513 on the sealing ring 351 can be single or multiple, depending on the actual waterproofing requirements.

[0102] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
