[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] This application provides an electrical connector, please refer to Figures 1 to 3 , Figures 1 to 3 A schematic structural diagram of the electrical connector provided in an embodiment of the present application.

[0044] Please see the attached Figure 1 The electrical connector 10 includes an electrical connector 1 , a connecting terminal 2 and a charging port terminal 3 .

[0045] The electrical connector 1 is the part that connects the connecting terminal 2 and the charging port terminal 3 and is responsible for transmitting current. The material of the electrical connector 1 is a material with good conductivity and mechanical strength, such as aluminum, gold, silver, copper, alloy, etc., to ensure the stability of current transmission and reduce energy loss.

[0046] The jumper terminal 2 is provided at one end of the electrical connector 1 in the length direction. The jumper terminal 2 is used to connect the battery system. In order to ensure good electrical contact and mechanical connection, the jumper terminal 2 can be fixedly connected to the battery system with fasteners. The jumper terminal 2 can be connected to the battery connector, and can also be connected to the high-voltage distribution box unit (PDU, Power Distribution Unit), integrated controller, distribution box, or maintenance switch, etc.

[0047] The charging port terminal 3 is arranged at the other end of the electrical connector 1 in the length direction. The charging port terminal 3 is used to connect to an external charging device (such as a charging pile). The charging port terminal 3 and the electrical connector 1 are integrally formed. The design of the charging port terminal 3 and the electrical connector 1 as one piece eliminates the connection gap between the charging port terminal 3 and the electrical connector 1 caused by connection methods such as screw connection, crimping connection or welding connection, reduces the contact resistance between the two, thereby reducing heat and improving charging efficiency and safety. The one-piece design also reduces the physical connection between the two, reduces the risk of loose connection caused by factors such as vibration and temperature changes, and improves the reliability and safety of the entire structure.

[0048] In the technical solution of the present application, by integrally forming the charging port terminal 3 and the electrical connector 1, the risk of loose connection caused by factors such as vibration and temperature change is reduced, the connection gap between the charging port terminal 3 and the electrical connector 1 is eliminated, and the contact resistance is effectively reduced, thereby reducing the heat generation caused by the contact resistance, thereby reducing heat generation, improving the safety and reliability of the charging process, and extending the life of the charging device 100.

[0049] In some embodiments, see Figure 2 The charging port terminal 3 is provided with a slot 31 for inserting the electrical connection terminal of an external charging device (such as a charging gun of a charging pile). In these embodiments, the charging port terminal 3 is provided with a slot 31, the size and shape of which match the electrical connection terminal of the external charging device, thereby achieving a physical and electrical connection between the electrical connector 10 and the external charging device to facilitate the transmission of electrical energy and the charging process. The slot 31 is designed with the convenience of quick plugging and unplugging in mind, allowing users to easily connect or disconnect the electrical connector 10 to the external charging device, improving the charging experience and efficiency.

[0050] In some embodiments, see Figure 2The electrical connector 10 further includes an elastic electrical contact 4 , which is disposed in the slot 31 . The elastic electrical contact 4 is used to elastically support the electrical connection terminal and the slot wall of the slot 31 when the electrical connection terminal is inserted into the slot 31 . In these embodiments, the elastic electrical contact 4 is disposed within the slot 31. When the electrical connection terminal of an external charging device (e.g., a charging gun of a charging pile) is inserted into the slot 31, the elastic electrical contact 4 can elastically resist the electrical connection terminal and the slot wall of the slot 31, ensuring that even in the case of slight external vibration or displacement, the electrical connection terminal can maintain stable contact with the charging port terminal 3 through the elastic electrical contact 4, reducing contact resistance and avoiding interruption or instability in current transmission. Through the use of the elastic electrical contact 4, even after multiple plugging and unplugging, good electrical contact can be maintained, preventing the reduction of power transmission efficiency or charging interruption caused by loose connection. The design of the elastic electrical contact 4 can reduce direct friction and wear between metal parts, thereby extending the service life of the electrical connector 10 and the external charging device. By integrating the elastic electrical contact 4, the electrical connector 10 not only achieves a stable connection with the external charging device, but also improves the reliability and durability of the connection, ensuring the efficiency and safety of the charging process. Specifically, the elastic electrical contact 4 is a spring, and the slot wall of the slot 31 is provided with a slot. When the spring is inserted into the slot 31, it is also fixed by the engagement of the buckle and the slot.

[0051] In some embodiments, see Figure 1 and Figure 2 The slot 31 has its opening located on the end face of the charging port terminal 3 facing away from the electrical connector 1. In these embodiments, the slot 31 has its opening located on the end face of the charging port terminal 3 facing away from the electrical connector 1, meaning that the slot 31 is oriented in the same direction as the length of the electrical connector 1. This also means that the insertion direction of the external charging device's electrical connector terminal into the slot 31 is aligned with the length of the electrical connector 1. The electrical connector terminal is smoothly inserted along the length of the electrical connector 1, avoiding instability that may result from lateral insertion and improving connection stability. When a user inserts the external charging device's electrical connector terminal, the direction is directly aligned with the length of the electrical connector 1, facilitating intuitive operation and reducing mis-insertion, thereby ensuring connection stability and convenient operation.

[0052] It is understood that when the battery of an electric vehicle or other device is being charged, the current passing through the electrical connector 10 generates heat. If this heat is not effectively managed, it may affect the performance and life of the connector and may even cause safety hazards. In some embodiments, see Figure 1 and Figure 2 A cooling channel 11 is provided in the electrical connector 1. In these embodiments, the cooling channel 11 allows a cooling medium (such as a coolant) to flow through the electrical connector 1 to remove the generated heat, thereby keeping the electrical connector 10 operating within a suitable temperature range.

[0053] In some embodiments, the cooling channel 11 extends along the length of the electrical connector 1. In these embodiments, the cooling channel 11 extends along the length of the electrical connector 1, which allows the cooling medium to cover a longer distance when flowing through the electrical connector 10, thereby more effectively absorbing and conducting heat and improving cooling efficiency.

[0054] As can be understood, the ratio of the cross-sectional area of ​​the cooling channel 11 to the cross-sectional area of ​​the electrical connector 1 is a critical design parameter, directly impacting cooling efficiency and the electrical performance of the electrical connector 1. A larger ratio, i.e., a larger cross-sectional area of ​​the cooling channel 11, provides more space for the cooling medium to flow, which improves cooling efficiency and removes more heat. However, an excessively large ratio may reduce the structural strength of the electrical connector 1 and the current it can transmit, thereby impacting its electrical performance.

[0055] In some embodiments, the cross-sectional area of ​​cooling channel 11 is 1% to 25% of the cross-sectional area of ​​electrical connector 1, ensuring effective heat dissipation while maintaining good structural strength and electrical performance. For example, when both electrical connector 1 and cooling channel 11 have circular cross-sectional shapes, the cross-sectional radius of cooling channel 11 is 10% to 50% of the cross-sectional radius of electrical connector 1.

[0056] In some embodiments, see Figure 1 and Figure 2 The number of the electrical connectors 1 is at least two, and the two cooling channels 11 of the two electrical connectors 1 are interconnected, so that the two electrical connectors 1 share the heat dissipation channel 5 . It is understandable that when the cooling channels 11 of two electrical connectors 1 are not connected, the cooling channels 11 of each electrical connector 1 must be independently connected to the cooling system, which not only increases the complexity and cost of the system, but may also reduce the cooling efficiency. In these embodiments, by sharing the heat dissipation channel 5, the cooling medium can flow continuously between multiple electrical connectors 1, increasing the contact area and time with the electrical connector 1, thereby improving the heat exchange efficiency and more effectively absorbing and dissipating heat. The shared heat dissipation channel 5 can significantly reduce the number of cooling pipes and interfaces, simplify the overall structure of the cooling system, reduce system complexity, reduce potential leakage points and maintenance costs, and reduce the use of cooling components, reduce material and manufacturing costs, and reduce the complexity and cost of installation and maintenance. The design of the shared heat dissipation channel 5 also helps to balance the temperature of each electrical connector 1, avoid local overheating, and improve the thermal stability and reliability of the entire system. The simplified design and reduced number of components help to optimize the internal spatial layout of the device, making the device more compact and more suitable for space-constrained application scenarios. In this way, the design of the electrical connector 1 sharing the heat dissipation channel 5 not only improves the cooling efficiency and system reliability, but also optimizes the system structure, saves costs, enhances environmental adaptability, and improves performance and thermal management efficiency.

[0057] In some embodiments, see Figure 1 and Figure 2 A first flow channel opening 12 is provided on the outer peripheral side of the electrical connector 1, and the first flow channel openings 12 of at least two adjacent electrical connectors 1 are connected to each other; a second flow channel opening 13 is also provided on the outer peripheral side of the electrical connector 1, and the second flow channel opening 13 is connected to the inlet or outlet of the heat dissipation channel 5. In these embodiments, the cooling medium starts from the inlet of the heat dissipation channel 5 and enters the internal cooling channel 11 of the electrical connector 1 through the second channel opening 13 of one of the electrical connectors 1. The cooling medium flows in the first electrical connector 1 and takes away heat through heat exchange with the electrical connector 1. The cooling medium flows out through the first channel opening 12 of the first electrical connector 1 and then enters the cooling channel 11 of the electrical connector 1 through the first channel opening 12 of the adjacent electrical connector 1. In the second electrical connector 1, the cooling medium continues to exchange heat with the electrical connector 1 and absorbs heat. After completing the cooling of the second electrical connector 1, the cooling medium returns to the heat dissipation channel 5 through the second channel opening 13 of the electrical connector 1 and flows out from the outlet of the heat dissipation channel 5. In this way, it can be ensured that the cooling medium flows continuously and effectively between multiple electrical connectors 1. By sharing the heat dissipation channel 5, the cooling efficiency is improved, while the cooling system structure is simplified, the cost is reduced, and the overall reliability of the system is improved.

[0058] It is understood that the cooling of the electrical connector 10 can utilize the vehicle's thermal management system. For example, the heat dissipation channel 5 can be connected to the vehicle's air conditioning system, and the cooling capacity of the air conditioning system can be used to cool the electrical connector 1. For example, through a dedicated heat exchanger, the cooling medium of the heat dissipation channel 5 and the cooling medium (such as refrigerant) of the air conditioning system can exchange heat to achieve cooling, which can share cooling equipment and reduce resource waste.

[0059] In some embodiments, see Figure 5 , Figure 5 Thinner lines indicate cooling channels, while thicker lines indicate electrical connections. The heat dissipation channel 5 is configured to communicate with the cooling pipe 200 of the vehicle's cooling system. In these embodiments, the heat dissipation channel 5 communicates with the cooling pipe 200 of the vehicle's cooling system, directly utilizing the vehicle's cooling pump, radiator, and other components, sharing the cooling medium and cooling equipment. This integrated design helps improve cooling efficiency while reducing additional costs and system complexity.

[0060] The present application does not specifically limit which cooling system cooling pipe 200 of the vehicle the heat dissipation channel 5 is connected to. Figure 5The straight arrows in the figure indicate the direction of the cooling medium flow. The heat dissipation channel 5 is connected in parallel with the cooling circuit of the power battery. The cooling medium is divided into two paths by a three-way valve or a diverter. One path flows through the power battery, and the other path flows through the heat dissipation channel 5 of the electrical connector 1. Finally, the two cooling media merge and return to the cooling system. They can share the expansion tank and water pump of the power battery cooling system. Similarly, the heat dissipation channel 5 can also be connected in parallel with the cooling system of the motor. The flow direction of the cooling medium can be adjusted by a control valve to ensure that both the electrical connector 1 and the motor are effectively cooled. For example, the heat dissipation channel 5 can be connected in parallel with the cooling system of the power electronic equipment, and a cooling pump and radiator are shared. A uniform cooling effect can be achieved through pipeline design and flow control.

[0061] In some embodiments, see Figure 1 and Figure 2 In the longitudinal direction of the electrical connector 1, the second flow channel opening 13 is positioned closer to the connecting terminal 2 than the first flow channel opening 12. In these embodiments, the second flow channel opening 13 is positioned closer to the connecting terminal 2 than the first flow channel opening 12, so that the inlet or outlet of the heat dissipation channel 5 is closer to the vehicle body. This simplifies the connection to the vehicle cooling system, shortens the length of the connecting pipes, reduces the complexity of the pipes and potential leak points, lowers the maintenance cost of the system, and achieves a more compact piping layout, which not only saves space but also reduces fluid resistance and improves the circulation efficiency of the cooling medium in the entire cooling system.

[0062] In some embodiments, see Figure 3 , the inner wall of the cooling channel 11 is provided with a first insulating layer 6. In these embodiments, the cooling channel 11 is provided in the electrical connector 1 and the first insulating layer 6 is provided on the inner wall of the cooling channel 11. This ensures that even if the cooling medium is conductive, electrical short circuits or leakage will not occur when the cooling medium flows through the electrical connector 1, thereby improving safety.

[0063] The present application does not limit the formation method of the first insulating layer 6. In some embodiments, the first insulating layer 6 is formed by combining Figure 1 and Figure 2The electrical connector 10 further includes an insulating tube 7, a portion of which is inserted into the cooling channel 11 to form a first insulating layer 6. A portion of the insulating tube 7 is connected between the first channel openings 12 of two adjacent electrical connectors 1 to form a portion of the heat dissipation channel 5. In these embodiments, the insulating tube 7 is partially inserted into the cooling channel 11, and its function is to directly form the first insulating layer 6, providing electrical isolation for the cooling channel 11. Another portion of the insulating tube 7 is connected between the first channel openings 12 of two adjacent electrical connectors 1, forming a partial structure of the heat dissipation channel 5. The insulating tube 7 not only serves as the first insulating layer 6 to provide the necessary electrical isolation, but also participates in the structural design of the heat dissipation channel 5. Through its connecting function, it ensures the continuity and integrity of the heat dissipation channel 5, thereby optimizing the heat dissipation performance of the entire electrical connector 1. By adjusting the insertion length and connection method of the insulating tube 7, it can adapt to the structural requirements of different electrical connectors 1 and cooling channels 11, and has good flexibility.

[0064] In some embodiments, see Figure 1 and Figure 2 The electrical connector 10 further includes an insulating tube 7, which is connected between the first flow channel openings 12 of two adjacent electrical connectors 1 to form a portion of the heat dissipation channel 5. In these embodiments, the insulating tube 7 forms a portion of the heat dissipation channel 5 between the first flow channel openings 12 of adjacent electrical connectors 1, and the implementation method of the first insulating layer 6 is not limited. The first insulating layer 6 can be an additional insulating tube or an insulating coating on the inner wall of the cooling channel 11. The additional insulating tube and the insulating coating provide a variety of implementation methods for the first insulating layer 6. The most suitable solution can be selected based on actual application requirements and cost considerations. For example, the insulating coating may be thinner, which is beneficial to space utilization, and the insulating coating may be more economical and help reduce costs. The additional insulating tube has a certain degree of independence, which is convenient for independent design, installation and maintenance. In this way, design flexibility and cost-effectiveness are provided, as well as convenience for maintenance and upgrading, ensuring the efficient and safe operation of the electrical connector 10 in various application scenarios.

[0065] The present application does not limit the material of the insulating tube 7. The material of the insulating tube 7 can be thermoplastic polyolefin (TPO), thermoplastic elastomer (TPE), polyamide (PA), thermoplastic polyurethane elastomer (TPU), polytetrafluoroethylene propylene (FEP), rubber plastic, polypropylene (PP), nylon 12 (PA12), etc.

[0066] In some embodiments, see Figure 1The jumper terminal 2 is integrally formed with the electrical connector 1. In these embodiments, the jumper terminal 2 is integrally formed with the electrical connector 1, providing better structural integrity, improving the mechanical strength of the electrical connector 10, reducing assembly steps, and reducing the risk of loosening. The direct connection between the jumper terminal 2 and the electrical connector 1 helps ensure good electrical contact, reduce contact resistance, and reduce heat generation, thereby improving the reliability and safety of the entire structure.

[0067] The present application does not limit the specific shape of the bridge terminal 2. In some embodiments, refer to Figure 1 and Figure 4 The connecting terminal 2 has a fastening hole 21 for inserting a fastener to connect the connecting terminal 2 to the battery system. In these embodiments, the presence of the fastening hole 21 allows the connecting terminal 2 to be tightly connected to the battery system using fasteners (such as screws, bolts, etc.), ensuring the stability of the electrical connection. The use of the fastener also achieves efficient connection and removal from the battery system.

[0068] In some embodiments, the electrical connector 1 is an aluminum rod or an aluminum alloy rod. In these embodiments, the use of an aluminum rod or an aluminum alloy rod as the material for the electrical connector 1 is based on the excellent properties of aluminum and its alloys, such as low density, good conductivity, easy processing, and relatively low cost. The use of an aluminum rod in electrical connections can provide a lightweight structure while maintaining sufficient mechanical strength and electrical performance. The aluminum alloy rod is enhanced by adding other elements to improve its strength and corrosion resistance, making it more suitable for use. It should be noted that the electrical connector 1 can be designed with a three-dimensional bend according to the internal structure of the vehicle to save space and fix the wiring. That is, this application does not limit the shape of the aluminum rod or aluminum alloy rod. The aluminum rod or aluminum alloy rod can be a straight rod or can be bent as needed.

[0069] The present application does not specifically limit the method of integrally forming the electrical connector 1 and the charging port terminal 3 and / or the jumper terminal 2. For example, the corresponding shape of the electrical connector 10 can be obtained by turning and drilling a metal rod. Alternatively, the electrical connector 10 of the corresponding shape can be directly manufactured by precision casting or powder metallurgy.

[0070] In some embodiments, see Figure 3 A second insulating layer 8 is provided on the outer periphery of the electrical connector 1. In these embodiments, the second insulating layer 8 can provide additional electrical isolation, preventing current leakage and short circuits, while also protecting the internal structure from physical damage, thereby improving the safety of the electrical connector 10. Specifically, the second insulating layer 8 can be made of a variety of materials, such as rubber, plastic, or a special insulating coating.

[0071] In some embodiments, see Figure 3A shielding layer 9 is provided on the outer periphery of the second insulating layer 8. Shielding layer 9 is typically made of a conductive material and can effectively reduce electromagnetic interference (EMI), protect the signal integrity within the electrical connector 1, enhance the electromagnetic compatibility (EMC) of the electrical connector 10, and ensure the reliability and safety of the electrical connector 10 in complex electromagnetic environments. Shielding layer 9 can be made of materials such as metal foil (such as aluminum tube), braided mesh, or conductive polymer.

[0072] According to the second aspect of this application, see Figure 4 A charging device 100 is provided, comprising an electrical connector 10 and a charging port holder 20. The structure of the electrical connector 10 is as described above. Since the charging device 100 adopts all the technical solutions of all the above embodiments, it at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the charging port holder 20 is provided with a mounting hole, and the charging port terminal 3 is inserted into the mounting hole, which can reduce the difficulty of installation, reduce installation time and manufacturing cost. For example, the charging port terminal 3 and the charging port holder 20 are pre-fixed to form a compact module. During installation, it is only necessary to align the entire module with the reserved position of the vehicle and fix it with a small number of screws or clips. This not only reduces the time of on-site installation, but also reduces the probability of installation errors. In the manufacturing process, this design makes the production process easier to automate, reduces the need for manual assembly, and thus reduces production costs. In summary, the design of fixing the charging port terminal 3 to the charging port holder 20 reduces the difficulty of installation and effectively controls manufacturing costs by simplifying the installation process, reducing installation time and optimizing the manufacturing process.

[0073] According to a third aspect of the present application, a vehicle is provided, comprising an electrical connector 10 or a charging device 100. The structure of the electrical connector 10 or the charging device 100 is as described above. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. This application does not limit the vehicle, including but not limited to electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs) and some extended-range electric vehicles (EREVs).

[0074] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0075] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0076] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0077] The above are merely preferred embodiments of the present application and do not constitute any form of limitation to the present application.
