Furthermore, precision-machined contact designs ensure the integrity and stability of signal transmission. Furthermore, advances in materials science have led to the application of new conductive and insulating materials, further improving connector electrical performance and environmental resistance.

[0004] However, despite these advances, automotive electrical connectors still face numerous challenges in terms of interference resistance. First, with the increasing complexity of automotive electronic systems, electromagnetic compatibility issues between different systems have become increasingly prominent, requiring connectors to not only resist external interference but also reduce the impact of their own electromagnetic radiation on other systems. Second, the use of high voltage and high current in new energy vehicles places higher demands on the connector's voltage resistance, temperature resistance, and thermal management capabilities. Improving anti-interference performance while ensuring safety is a major challenge. Furthermore, with the development of autonomous driving technology, the requirements for data transmission speed and accuracy are high. Any slight signal distortion or delay may affect the overall performance of the system, which poses a challenge to the connector's anti-interference ability and signal integrity.

[0005] Therefore, further optimizing the structural design of automotive electrical connectors and improving their anti-interference capabilities while also balancing cost-effectiveness, lightweight design, and ease of installation and maintenance have become pressing challenges in the automotive electronics field. This technical solution addresses this need by proposing an innovative automotive electrical connector design. Through structural innovation and material optimization, it aims to achieve a higher level of anti-interference performance, meeting the development needs of future automotive electronic systems.

[0034] With the accelerated advancement of automobile electrification and intelligentization, the number and complexity of electronic devices integrated inside automobiles are growing exponentially. From power system control, safety-assisted driving to in-vehicle infotainment and autonomous driving technology, electrical connections and signal transmission between systems have become key links in ensuring the overall performance and safety of the automobile. As the core component for realizing these electrical connections, the performance of the automobile's electrical connector is directly related to the stable operation of the automobile's electronic system and the accuracy of data transmission. Especially in the current situation where automobiles are facing increasingly complex electromagnetic environment challenges, the anti-interference ability of electrical connectors has become an important indicator for measuring their performance. This application provides an electrical connector with high anti-interference performance, optimized structure and suitable for complex working conditions in automobiles. The electrical connector will be introduced in detail below, which effectively improves the anti-interference performance and ensures stable and reliable operation in the complex electromagnetic environment of automobiles. Please refer to Figures 1 to 5 As shown, an electrical connector for a car in a preferred embodiment of the present application includes a connector body 100 , and the connector body 100 includes a first connecting end 110 and a second connecting end 120 ;

[0035] The first connecting end 110 includes a first base 111 and a shell 112. The first base 111 includes a main connecting hole 114 and an auxiliary connecting hole 115. An annular cavity 113 is formed between the first base 111 and the shell 112;

[0036] The second connecting end 120 includes a second base 121 and a connecting groove 122. The connecting groove 122 is formed in the second base 121 and includes a main groove 123 and independent connecting sub-grooves 124. The main groove 123 is an annular groove. Each connecting sub-groove 124 corresponds to the main connecting hole 114.

[0037] The shielding member 320 extends from the first base 111 to the shell 112 and around the connecting groove 122;

[0038] The electrical connector 310 extends from the first connection end 110 to the second connection end 120 and is electrically connected to the outside in the main connection hole 114 and the connection sub-groove 124 respectively;

[0039] The first connection end 110 and the second connection end 120 are formed integrally, and the shielding member 320 is connected to the external ground through the auxiliary connection hole 115 on the first base body 111 .

[0040] The electrical connector of this application primarily comprises a connector body 100, which is constructed as an integrated structure, enhancing the overall performance and durability of the product. Connector body 100 seamlessly integrates a first connection end 110 and a second connection end 120, both of which are manufactured using an integrated molding process. This ensures high consistency in the connector's mechanical strength and electrical performance, simplifying the assembly process and reducing performance degradation due to assembly errors. It also enhances the connector's resistance to vibration and impact in complex operating conditions.

[0041] The first connector 110 comprises a first base 111 and a housing 112, forming an annular cavity 113 between them to accommodate the corresponding plug structure. The first base 111 is provided with a primary connection hole 114 and a secondary connection hole 115. The primary connection hole 114 is used to receive and secure the external plug terminal for electrical connection; the secondary connection hole 115 is used to ground the shielding element 320, ensuring the continuity and effectiveness of the electromagnetic shielding effect.

[0042] The second connector 120 consists of a second base 121 and an internal connection slot 122. This slot 122 is further subdivided into an annular main slot 123 and multiple independent sub-slots 124. Each sub-slot 124 corresponds to the main connection hole 114 of the first connector 110. This allows the electrical connector 310 to connect independently and stably, effectively preventing signal interference and improving the accuracy and reliability of signal transmission. The annular design of the main slot 123 facilitates the insertion of another plug, and combined with the comprehensive coverage of the shielding member 320, further enhances the connector's ability to resist electromagnetic interference.

[0043] The shielding element 320 extends from the interior of the first base 111 to the perimeter of the housing 112 and the connection slot 122 of the second connector 120, forming a continuous electromagnetic shielding layer. This effectively isolates external electromagnetic radiation, protects the internal electrical connector 310 from interference, and prevents electromagnetic radiation generated by the connector itself from affecting other systems. The shielding element 320 is connected to the external ground through the auxiliary connection hole 115 in the first base 111. As the core component of the connector, the electrical connector 310 extends from the main connection hole 114 of the first connector 110 to the connection sub-slot 124 of the second connector 120, ensuring a reliable electrical connection between the external plug terminals.

[0044] Through its integrated design, annular cavity 113 structure, comprehensive shielding, and independent connection sub-slots 124, this electrical connector improves its resistance to electromagnetic interference, ensuring accurate and reliable signal transmission. The one-piece molding process and enhanced mechanical structure ensure stable electrical connection performance and a long service life. Comprehensive electromagnetic shielding allows the connector to adapt to the increasingly complex electromagnetic environment within the vehicle, ensuring the stable operation of the vehicle's electronic systems.

[0045] The main connection holes 114 and the auxiliary connection holes 115 are both arranged on the same plane of the first base. This design achieves a compact internal structure layout of the connector and convenient function implementation through a highly integrated hole setting. The main connection holes 114 and the auxiliary connection holes 115 are located on the same plane, so that during the assembly process, the operator can more intuitively and conveniently insert the plug terminal and ground the shield 320 without the need for complex adjustments in different planes or angles.

[0046] The hole design on the same plane helps to ensure that the connection between the plug terminal and the main connection hole 114, and between the shielding part 320 and the auxiliary connection hole 115 is more stable and reliable. The holes in the shielding part 320 can correspond to the matching positioning posts, reducing stress concentration or loose connections that may occur due to the holes not being in the same plane, ensuring the long-term stability of the electrical connection, and reducing the risk of signal attenuation or interruption due to poor connection.

[0047] The auxiliary connection hole 115 is used for the ground connection of the shielding part 320. Setting it on the same plane as the main connection hole 114 helps to ensure that the electrical connection between the shielding part 320 and the first base is tighter and more continuous, reducing the possibility of electromagnetic interference signals leaking through the ground path, further enhancing the connector's anti-electromagnetic interference capability, and providing more reliable electromagnetic protection for the vehicle's electrical system.

[0048] When the connector requires maintenance or repair, the coplanar placement of the holes allows operators to more easily check the connection status of the plug terminals and shield 320, quickly locating and resolving any issues, reducing maintenance effort and costs and improving the connector's maintainability. Placing the primary and secondary connection holes 114 and 115 on the same plane facilitates a compact design of the connector's internal structure, reducing unnecessary space usage and enabling the integration of more functional components within a limited space, meeting the demand for miniaturization in automotive electrical systems.

[0049] The first connection end 110 and the second connection end 120 are precisely arranged along the same axis, extending in a straight line with their centers aligned. This coaxial and center-aligned design ensures the regularity of the connector's overall structure and the linearity of the signal transmission path. This center-aligned, extended design minimizes the transmission path between the first connection end 110 and the second connection end 120 of the electrical connector 310 and minimizes signal attenuation and distortion during transmission, helping to maintain signal integrity and stability and improving the accuracy and rate of data transmission. The coaxial, center-aligned structural design enhances the mechanical stability of the connector. When subjected to external forces (such as vibration and impact), this design can better disperse stress, reducing structural damage or loose connections caused by stress concentration. This improves the durability and reliability of the connector under complex operating conditions.

[0050] The center-aligned design makes it easier to precisely align the first connection end 110 and the second connection end 120 during assembly, reducing assembly difficulties or performance degradation caused by alignment deviations and improving assembly efficiency and accuracy. The coaxial structure helps optimize the connector's electromagnetic compatibility. The center-aligned design reduces the leakage path of electromagnetic radiation, reducing electromagnetic interference to surrounding electronic equipment. It also helps improve the connector's resistance to external electromagnetic interference and protects internal circuits from damage. It helps achieve miniaturization and integration of connectors, allowing more functional components and connection interfaces to be integrated within a limited space, meeting the high space utilization requirements of automotive electronic systems.

[0051] The first housing 111 houses multiple independent, functionally separate connectors. Each connector is surrounded by a shielding element 320, forming a locally independent electromagnetic protection unit. This refined shielding structure provides electromagnetic protection for each connector, ensuring the connector's high-performance operation in complex electromagnetic environments. Shielding elements 320 surround each connector, creating an independent electromagnetic shielding space. This effectively isolates electromagnetic interference between adjacent connectors, preventing signal crosstalk and noise coupling, and improving signal transmission purity and accuracy. The independent shielding structure reduces electromagnetic radiation interference with the connector's internal signals, ensuring signal integrity and stability during transmission, reducing the risk of signal distortion or loss due to electromagnetic interference, and improving the overall reliability of the connector. In complex electromagnetic environments, such as those in automobiles, multiple connectors operating simultaneously are prone to mutual interference. This design provides independent shielding for each connector, effectively preventing both external electromagnetic radiation and electromagnetic interference between internal connectors. While providing electromagnetic protection, shielding elements 320 also serve as a heat transfer path, dissipating heat from the connector. A well-designed shielding structure helps improve the connector's thermal management efficiency and prevent performance degradation or damage due to overheating. It is conducive to the modularization and standardization of electrical connectors. By integrating multiple connectors and their shielding structures into one seat, a standardized connection module can be formed, which is convenient for rapid adaptation and replacement.

[0052] Reinforcing ribs 400 are incorporated into the internal or external structure of the second connection end 120. These ribs 400 are distributed across the stress-bearing areas of the second connection end 120, forming a supporting framework that enhances the connection end's structural strength and deformation resistance. By increasing the second connection end 120's cross-sectional area and material density, the ribs 400 effectively improve its ability to withstand external forces. The ribs 400 design reduces structural damage or fatigue cracks caused by stress concentration, thereby extending the connector's service life. The layout and shape of the ribs 400 are designed to evenly distribute external forces, reducing deformation of the connection end under stress. This ensures that the connector maintains stable geometry and dimensional accuracy during long-term use, thereby ensuring the reliability and stability of the electrical connection. In environments with large temperature fluctuations, connectors may generate thermal stress due to thermal expansion and contraction. The ribs 400 design helps optimize the distribution of thermal stress within the connection end, reducing structural deformation or damage caused by thermal stress concentration, and improving the connector's adaptability to extreme temperature conditions. The presence of the reinforcing ribs 400 stabilizes the second connection end 120 during assembly, reducing potential misalignment or loosening due to improper assembly or external forces. By rationally arranging the reinforcing ribs 400, the connector's structural strength can be enhanced without significantly increasing its overall weight, contributing to its lightweight design. The design of the reinforcing ribs 400 effectively absorbs and disperses vibration and impact energy, reducing its impact on the connector's internal electrical components. This improves the connector's vibration and impact resistance, ensuring a consistently stable electrical connection.

[0053] The annular cavity 113 is designed as a special-shaped cavity structure with specific geometric characteristics. Its outline is not a traditional regular shape. At the same time, the main body groove 123 also adopts a special-shaped annular groove design. The shape and size of the special-shaped annular groove have been calculated to adapt to the specific layout of the electrical connector 310 and enhance the overall structural performance. The design of the special-shaped cavity and special-shaped annular groove can more flexibly adapt to the complex spatial structure inside the connector, make full use of the available space, and integrate more functional components within a limited volume, which helps to achieve miniaturization and compact design of automotive electrical connectors and meet the needs of small installation spaces. Compared with traditional regular shapes, the special-shaped structure can better disperse stress and improve the overall mechanical strength of the connector. When subjected to external forces, the unique shape of the special-shaped cavity and special-shaped annular groove can evenly distribute stress to the surrounding materials, avoiding structural damage caused by local stress concentration, thereby enhancing the stability and durability of the connector under complex working conditions. The shape and size of the special-shaped annular groove are customized according to the specific layout and shape of the electrical connector 310, which can ensure that the electrical connector 310 is accurately positioned and stably connected in the groove, reduce the shaking and displacement of the electrical connector 310 in the groove, and improve the reliability and stability of the electrical connection.

[0054] In the internal structure of the annular cavity 113 and / or the main body groove 123, a limiting guide strip is further provided. The limiting guide strip is distributed at a specific position and intervals to provide positioning and guiding functions for the electrical connector 310 or related components inserted therein, thereby ensuring the accuracy and efficiency of the assembly process. At the same time, a sealing liquid can be further introduced. The sealing liquid has unique physical and chemical properties, that is, it can be dissolved in a specific organic solvent, but remains stable and insoluble in water. An observation and operation hole is opened at a specific position on the side wall of the shell 112, through which the state of the sealing liquid can be visually observed. The provision of the limiting guide strip improves the assembly accuracy of the electrical connector 310 or related components in the annular cavity 113 and / or the main body groove 123, reduces the offset and misalignment during the assembly process through positioning and guiding, ensures the reliability and stability of the electrical connection, and also improves the assembly efficiency and reduces the rework and maintenance costs caused by improper assembly. The use of a special sealing liquid enhances the connector's sealing performance. This sealing liquid is soluble in organic solvents, making it easy to replace or replenish the sealing liquid when needed. It remains stable and insoluble in water, effectively preventing moisture from entering the connector, protecting the electrical connector 310 from humid environments and extending the connector's service life. This design allows the connector to adapt to a wider range of environmental conditions. In humid or water-rich environments, the sealing liquid effectively isolates moisture and protects the internal circuitry. When maintenance or replacement is required, the connector can be removed by dissolving it with an organic solvent, eliminating the need for complex disassembly tools or procedures, enhancing the connector's versatility and practicality.

[0055] Shielding component 320 utilizes an advanced injection molding process, achieving integrated manufacturing with the plastic component. During the injection molding process, shielding material with specific conductive properties and shielding effectiveness is precisely embedded into the pre-set position of the plastic component mold. As the high-temperature plastic melt is injected and solidifies through cooling, shielding component 320 and the plastic component become tightly integrated, forming a seamless, integrated structure. Furthermore, after the injection molding process, high-precision punching equipment is used to precisely drill the connection holes in the shielding component 320 at the designated locations according to design requirements. This ensures the dimensional and positional accuracy of the connection holes, ensuring that they meet the requirements for subsequent electrical connections and shield grounding.

[0056] By forming the shielding component 320 directly into the plastic component through injection molding, the shielding component 320 and the plastic component are integrated into one design, which can effectively reduce the electromagnetic leakage path, improve the shielding effectiveness, and provide more reliable electromagnetic protection for the electrical connector 310 inside the connector. At the same time, the integrated structure enhances the overall mechanical strength of the connector and reduces the risk of shielding performance degradation due to loose or separated components. The injection molding process is characterized by high efficiency and mass production, and can quickly produce a large number of consistent integrated products of the shielding component 320 and the plastic component. Compared with traditional assembly processes, the number of assembly steps is reduced and production efficiency is improved. Punching after the injection molding is completed can ensure the dimensional accuracy and positional accuracy of the connection holes, and can accurately control the hole diameter, hole depth and hole position deviation to meet the electrical connection and shielding grounding requirements. The punching method avoids the problem of connection hole dimensional deviation caused by mold wear or deformation during the injection molding process, thereby improving product quality and reliability.

[0057] The injection molding process allows for flexible adjustment of the layout, shape, and size of the shielding element 320 within the plastic part to meet varying design requirements. By varying the mold design, it is easy to manufacture integrated shielding element 320 and plastic parts in varying specifications and models, enabling the connector to better adapt to the needs of various automotive electrical systems. The integrated injection molding process creates a smooth transition between the shielding element 320 and the plastic part surface, without noticeable seams or protrusions, improving the product's appearance. Furthermore, the tightly integrated structure enhances the connector's sealing, effectively preventing the intrusion of external impurities such as moisture and dust, protecting the electrical connector 310 from damage and extending the product's service life.

[0058] The first base body 111 is designed and integrated with a terminal seat structure and a terminal clamp 600 that matches it. The terminal seat structure is customized according to the shape, size and electrical performance requirements of the electrical connection terminal, and is provided with precise positioning grooves and support surfaces inside to stably support the electrical connection terminal. The terminal clamp 600 adopts a unique snap-on or elastic snap-on mechanism, which can cooperate closely with the terminal seat structure, and firmly fix the electrical connection terminal in the first base body 111 through mechanical snap-on action, ensuring that the electrical connection terminal will not loosen or shift under complex working conditions. Furthermore, a metal shielding part 320 is integrated into the terminal clamp 600, and the metal shielding part 320 is tightly combined with the clamp to form a continuous electromagnetic shielding layer, providing all-round electromagnetic protection for the electrical connection terminal.

[0059] The precise matching of the terminal seat structure and the terminal clip 600 firmly fixes the electrical connection terminal through mechanical snap-fitting, effectively preventing the terminal from loosening or shifting due to external forces such as vibration and impact, ensuring the stability and reliability of the electrical connection, and reducing the risk of poor contact or short circuit. The metal shielding member 320 inside the terminal clip 600 is tightly combined with the clip to form a continuous electromagnetic shielding layer, which effectively blocks the influence of external electromagnetic interference on the electrical connection terminal, while further reducing the interference of the electromagnetic radiation generated by the electrical connection terminal itself on surrounding electronic equipment. The matching design of the terminal seat structure and the terminal clip 600 simplifies the assembly process. The electrical connection terminal only needs to be placed in the terminal seat structure and then snapped in with the terminal clip 600 to complete the fixation. The positioning groove and support surface ensure the assembly accuracy of the electrical connection terminal.

[0060] The terminal connector 600 utilizes a unique snap-on or elastic snap-on mechanism, providing excellent mechanical strength and durability. It can withstand various mechanical stresses without damage or deformation during long-term use, ensuring the long-term, stable fixation of the electrical connector. When maintenance or replacement of the electrical connector is required, simply release the terminal connector 600 and the connector can be easily removed for replacement or repair, improving maintenance convenience and efficiency while reducing maintenance costs and time.

[0061] The shell is designed to have a claw hole 500 with specific structural features and functional orientation. The shape, size and layout position of the claw hole 500 on the shell are determined after comprehensive consideration of multiple factors such as the claw structure to be matched with it, the overall mechanical performance requirements of the connector and the assembly process requirements. The inner wall of the claw hole 500 has been processed and has a smooth surface and high dimensional accuracy to ensure a tight and stable fit with the claw. The claw hole 500 provides a clear assembly guide and positioning reference for the claw. During the assembly process, the claw can be quickly and accurately inserted into the claw hole 500 to achieve precise docking between the shell and other components, reducing assembly errors and time costs, and improving production efficiency. At the same time, precise positioning also ensures the relative position relationship between the components inside the connector, ensuring the reliability of the electrical connection.

[0062] The tight fit between the claw and the claw hole 500 forms a reliable mechanical connection. Once inserted into the claw hole 500, the claw generates sufficient friction or clamping force through its own elastic deformation or the special structural design of the claw hole 500 (such as barbs and grooves), preventing the housing from loosening or falling off when subjected to external forces (such as vibration and impact), thereby enhancing the overall structural stability and reliability of the connector. The layout and structural design of the claw hole 500 effectively direct and distribute the mechanical loads experienced by the connector during use. By locating the claw hole 500 at a critical stress-bearing location on the housing, the claw and the claw hole 500 share the load, preventing structural damage or fatigue cracks caused by localized stress concentration, thereby improving the mechanical performance and service life of the connector. When the housing needs to be disassembled for maintenance or component replacement, the design of the claw hole 500 facilitates disassembly, releasing the clamping force between the claw and the claw hole 500 and enabling quick removal of the housing. In addition, the standardized claw hole 500 design enables the housing to match a variety of claw structures of different specifications and models, thereby improving the versatility and compatibility of the product. This helps connector manufacturers to flexibly select and match components according to different market demands and customer requirements, and quickly develop products that meet diverse needs. If the claw hole 500 and the claw are reasonably designed to match, while achieving mechanical connection, it can also play a certain sealing role. For example, by providing a sealing ring in the claw hole 500 or adopting a special sealing structure design, it can effectively prevent external impurities such as moisture and dust from entering the interior of the connector through the claw hole 500, protect the internal electrical connector 310 from damage, and improve the sealing performance and environmental adaptability of the connector.

[0063] From the foregoing, it can be seen that the electrical connector for automobiles of the present application has an integrated connector body, which is composed of a first connection end and a second connection end arranged along the same axis and extending in a center-aligned manner. This design ensures the regularity of the overall structure of the connector, the linearity of the signal transmission path, and the mechanical stability, which helps to reduce signal attenuation and distortion, improve data transmission accuracy and rate, enhance the durability and reliability of the connector under complex working conditions, and optimize electromagnetic compatibility, facilitating miniaturization and integration.

[0064] The first connection end includes a first base and a shell, and an annular cavity is formed between the two to accommodate the corresponding structure of the plug. The first base is provided with a main connection hole and an auxiliary connection hole. The main connection hole is used to receive and fix the external plug terminal to achieve electrical connection, and the auxiliary connection hole is used for grounding connection of the shielding part. The two are arranged on the same plane to facilitate assembly operation, ensure stable and reliable connection, enhance anti-electromagnetic interference capability, improve maintainability, and achieve compact design. Multiple independent and functionally partitioned connectors are arranged inside the first base. Each connector is wrapped by a shielding part that surrounds it in all directions, forming a locally independent electromagnetic protection unit, which effectively isolates electromagnetic interference, improves the purity and accuracy of signal transmission, reduces the risk of signal distortion or loss, and can also assist in heat dissipation, improve thermal management efficiency, and is conducive to modularization and standardization. The first base body is also designed and integrated with the terminal seat structure and terminal clamping parts. The terminal seat structure has precise positioning grooves and support surfaces. The terminal clamping parts adopt a unique snap-on or elastic clamping mechanism. The two work closely together to firmly fix the electrical connection terminals. The metal shielding parts are integrated into the terminal clamping parts to form a continuous electromagnetic shielding layer, ensuring the stability and reliability of the electrical connection, blocking external electromagnetic interference, simplifying the assembly process, improving maintenance convenience, and reducing maintenance costs.

[0065] The second connector consists of a second base and an internal connection slot. The connection slot includes an annular main slot and multiple independent sub-slots. The main slot facilitates plug insertion, while the sub-slots correspond to the main connection holes, enabling independent and stable connection of the electrical connectors. This prevents signal interference and improves signal transmission accuracy and reliability. Combined with full shielding, the second connector features enhanced electromagnetic interference resistance. Ribs are incorporated internally or externally in stress-bearing areas to form a support framework, enhancing structural strength and deformation resistance, reducing stress concentration and extending service life. They evenly distribute external forces, reduce deformation, optimize thermal stress distribution, improve assembly stability, achieve lightweight design, and enhance vibration and shock resistance. The annular cavity and main slot feature a special profile design to more flexibly adapt to complex internal structures, enabling miniaturization and compactness. This design distributes stress, improves mechanical strength, and ensures precise positioning and stable connection of the electrical connectors. Positioning guides are incorporated within the annular cavity and / or main slot to improve assembly accuracy and efficiency. A special sealing liquid, whose status can be visually monitored through the housing's sidewall inspection and operation holes, enhances sealing performance, adapts to various environmental conditions, and enhances versatility and practicality.

[0066] Shielding components are manufactured using advanced injection molding techniques and integrated with plastic components. They are precisely inserted into pre-set locations during the molding process, tightly bonded after cooling and solidification, and then precisely punched to meet subsequent needs. This integrated design reduces electromagnetic leakage paths, improves shielding effectiveness, enhances overall mechanical strength, and increases production efficiency. It ensures precise dimensional and positioning accuracy of the connection holes, flexibly adapts to different design requirements, and improves appearance quality and sealing.

[0067] The housing features claw holes, whose shape, size, and layout are carefully considered. The smooth inner wall and high dimensional accuracy ensure a tight fit with the claws. The claw holes provide assembly guidance and positioning datums for the claws, enabling precise docking and reducing assembly errors and time costs. They form a reliable mechanical connection with the claws, preventing loosening or falling out, enhancing structural stability and reliability. They also rationally guide and distribute mechanical loads, improving mechanical performance and service life. They facilitate disassembly and enhance maintenance convenience. The standardized design enhances versatility and compatibility. A properly coordinated design also provides a sealing effect, improving sealing performance and environmental adaptability.

[0068] In summary, the electrical connector of the present application has excellent performance in terms of anti-electromagnetic interference, signal transmission stability, mechanical strength, assembly convenience, maintainability, miniaturization and integration through a variety of innovative designs, and can meet the use requirements of automotive electrical systems in complex environments.

[0069] The above is only a specific implementation of the present application. Any other improvements made based on the concept of the present application are considered to be within the scope of protection of the present application.
