[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0054] Firstly, please refer to Figure 1 and Figure 2 This application provides a connection device 10, including a conductive busbar 111 and a cooling channel 121. The conductive busbar 111 is a flat conductor, and the cooling channel 121 is used to contain a cooling medium for heat dissipation from the conductive busbar 111. By containing the cooling medium in the cooling channel 121, heat exchange between the cooling medium and the conductive busbar 111 can be achieved, improving the heat dissipation and cooling effect of the conductive busbar 111, reducing the decrease in current carrying capacity caused by excessive heat in the conductive busbar 111, and ensuring the performance stability of the conductive busbar 111.

[0055] That is, during the operation of the connecting device 10, heat is generated when the conductive bus 111 carries current. The cooling channel 121 contains a cooling medium, which can exchange heat with the conductive bus 111, thereby improving the heat dissipation and cooling effect of the conductive bus 111. Compared with the passive heat dissipation of the conductive bus 111 in the conventional technology, the connecting device 10 provided in this application embodiment can significantly improve the heat dissipation and cooling effect, thereby ensuring the current carrying capacity of the conductive bus 111 and improving the operational stability of the connecting device 10.

[0056] The cooling medium in the cooling channel 121 can be a coolant or a phase change material. The coolant enables heat exchange and improves heat dissipation. The phase change material can remove the heat generated by the busbar 111 through the conversion between liquid and gaseous states.

[0057] In some embodiments, the connection device includes: a plurality of conductive bars arranged in parallel, with a cooling channel provided between at least two adjacent conductive bars. The plurality of conductive bars 111 arranged in parallel enable connections between the plurality of conductive bars 111 and terminals such as positive and negative terminals in the battery pack. The cooling channel 121 provided between at least two conductive bars 111 allows the cooling medium in the cooling channel 121 to exchange heat with the at least two adjacent conductive bars 111, ensuring effective heat dissipation while reducing the number of cooling channels 121 required.

[0058] For example, such as Figure 1 As shown, the connecting device 10 includes two parallel conductive bars 111, which together form a conductive element 11. The two conductive bars 111 are used to connect to the positive and negative terminals of the battery pack, respectively, thereby realizing current transmission.

[0059] In some embodiments, the cooling channel 121 is insulated from the conductive busbar 111. By insulating the cooling channel 121 from the conductive busbar 111, the risk of short circuits and leakage of the conductive busbar 111 can be reduced, improving safety performance. It can also reduce the corrosion and electrochemical damage of the cooling medium to the conductive busbar 111, extending the service life of the conductive busbar 111, and ensuring good insulation performance while maintaining heat dissipation.

[0060] In some embodiments, the connecting device 10 further includes an insulating member 12. The insulating member 12 is provided with a first cavity that extends along the length of the conductive busbar 111 and is configured as a cooling channel 121.

[0061] By constructing a cooling channel 121 within the insulating member 12, the insulating member 12 enables the cooling channel 121 to be insulated from the connecting device 10, achieving integrated design, improving the structural compactness of the connecting device 10, ensuring cooling uniformity, and reducing local overheating.

[0062] In some embodiments, the insulating member 12 further includes a second cavity extending along the length of the conductive busbar 111 and used to mount the conductive busbar 111 so that the insulating member 12 covers the conductive busbar 111. The second cavity is disposed circumferentially to the first cavity, adjacent to it, and isolated from it. This arrangement allows the insulating member 12 to provide insulation protection for the conductive busbar 111, and integrates the cooling channel 121 and the conductive busbar 111, improving structural compactness. Simultaneously, it forms a heat transfer path of "heat source-insulation layer-cooling medium," improving heat dissipation efficiency.

[0063] In some embodiments, at least two conductive bars 111 are arranged side by side along the thickness direction of the connecting device 10. By arranging at least two conductive bars 111 along the thickness of the conductive bar 111, space utilization can be improved, the compactness of the connecting device 10 can be increased, and the two conductive bars 111 arranged side by side along the thickness direction of the conductive bar 111 can also enhance the structural stability of the conductive bar 111.

[0064] In some embodiments, the connecting device 10 includes at least two conductive bars, and the insulating member 12 includes at least two second cavities, with the conductive bars 111 corresponding to the second cavities one-to-one. By making the conductive bars 111 correspond one-to-one with the second cavities in the insulating member 12, a multi-channel insulating barrier can be formed, improving the insulation performance, and the conductive bars 111 form independent heat-generating areas, improving the heat dissipation effect.

[0065] For example, please refer to Figure 1 The insulating member 12 has two second cavities, and the two conductive bars 111 are respectively installed in the second cavities, so that the conductive bars 111 are isolated from the outside world by the insulating member 12, and the two conductive bars 111 are also isolated by the insulating member 12. The insulating member 12 can also improve the structural stability of the two conductive bars 111, so that the two conductive bars 111 are kept in a parallel arrangement.

[0066] In some embodiments, at least two second cavities are isolated from each other. By isolating at least two second cavities from each other, mutual interference between the conductive busbars 111 can be reduced.

[0067] In some embodiments, the insulating member 12 is a one-piece molded structure. The one-piece molded insulating member 12 can form a stable integral structure encompassing at least two conductive bars 111 and the cooling channel 121, reducing loosening or displacement. The one-piece molded insulating member 12 can effectively isolate adjacent conductive bars 111 and cooling channels 121, preventing electrical short circuits or leakage, and also reducing the influence of external factors on the conductive bars 111 and cooling channels 121, improving the safety and reliability of the connection device 10. Furthermore, the one-piece molded insulating member 12 can more tightly cover at least two conductive bars 111, reducing the gap between the insulating member 12 and the conductive bars 111, and improving the space utilization of the connection device 10.

[0068] In some embodiments, please refer to Figure 1 The connecting device 10 also includes a shielding layer 13, which covers the periphery of the insulating component 12. The shielding layer 13 covers the periphery of the insulating component 12 and can effectively shield the electromagnetic field generated by the conductive busbar 111, reducing electromagnetic interference to other components in the vehicle.

[0069] Because at least two conductive bars 111 are arranged side-by-side in this embodiment, the structure is compact and enclosed within the same insulating element 12, allowing at least two conductive bars 111 to be simultaneously enclosed by a single shielding layer 13. Compared to the conventional approach where each conductive bar 111 has its own separate insulating element 12 and shielding layer 13, the connection device 10 provided in this embodiment has a more compact structure, occupies less space, and thus reduces the difficulty of arrangement. Furthermore, it also saves on the materials used for the insulating element 12 and shielding layer 13, reducing costs and contributing to the lightweight design of the connection device 10.

[0070] In some embodiments, please refer to Figure 1 The connecting device 10 also includes a protective layer 14, which covers the periphery of the shielding layer 13. The protective layer 14 provides mechanical protection for the shielding layer 13, as well as the insulating components 12 and conductive busbars 111 located within the shielding layer 13, reduces physical damage to the shielding layer 13, increases the strength of the connecting device 10, and provides anti-corrosion and flame-retardant properties, thereby ensuring the stability of the connecting device 10.

[0071] In some embodiments, please refer to Figure 3 The first end of the conductive busbar 111 is provided with a first connection terminal 15. The first connection terminal 15 is configured to connect to the charging connection terminal 21 of the charging socket 20.

[0072] By connecting the first connection terminal 15 on the connecting device 10 and the charging connection terminal 21 in the charging socket 20, an electrical connection between the connecting device 10 and the charging socket 20 can be achieved.

[0073] In some embodiments, the first connection terminal 15 is adapted to be detachably connected to the charging connection terminal 21. This detachable connection facilitates the installation and removal of the connection device 10 and the charging socket 20, improving maintenance convenience and reducing installation difficulty.

[0074] In some embodiments, the first connecting terminal 15 includes a bolt structure, and the charging connecting terminal 21 includes a threaded structure. The first connecting terminal 15 is adapted to be connected to the charging connecting terminal 21 via the bolt structure and the threaded structure. The bolt structure and the threaded structure can improve the efficiency of assembly and disassembly of the first connecting terminal 15 and the charging connecting terminal 21, reduce the difficulty of assembly and disassembly, and ensure the connection stability between the two.

[0075] It is understood that the first connection terminal 15 and the charging connection terminal 21 can also adopt other detachable connection methods, such as snap-fit ​​connection, pin connection, clamp connection or sleeve connection.

[0076] In some embodiments, a first conductive plating layer is provided on the surface of the first connection terminal 15. By providing the first conductive plating layer on the surface of the first connection terminal 15, the electrical connection performance between the busbar 111 and the charging socket 20 can be improved, thereby increasing the current carrying capacity.

[0077] For example, the first conductive plating layer can be a silver plating layer. Silver has high conductivity, which can ensure higher electrical transport performance. In addition, the silver plating layer also has good chemical stability and anti-oxidation properties, which can ensure the stability and reliability of the electrical connection.

[0078] In some embodiments, referring to FIG. 3, a first end cap 171 is fitted onto the first end of the conductive bar 111. The first end cap 171 is configured to be connected to the socket housing 22 of the charging socket 20.

[0079] By connecting the first end cap 171 to the socket housing 22, the stability of the connection between the connecting device 10 and the charging socket 20 can be improved. That is, on the one hand, the connecting device 10 can be connected to the charging connection terminal 21 of the charging socket 20 through the first connection terminal 15, and on the other hand, the connecting device 10 can also be connected to the socket housing 22 through the first end cap 171.

[0080] In some embodiments, please refer to Figure 3 A first sealing element 172 is provided between the first end cap 171 and the housing. The first sealing element 172, which is provided between the first end cap 171 and the housing of the charging socket 20, can ensure the sealing connection performance between the connecting device 10 and the charging socket 20, improve the sealing degree between the charging socket 20 and the connecting device 10, and achieve a waterproof effect.

[0081] In some embodiments, please refer to Figure 4 The second end of the conductive busbar 111 is provided with a second connection terminal 16, which is configured to be connected to the battery pack. That is, the second end of the conductive busbar 111 is provided with a second connection terminal 16, so that the conductive busbar 111 can be connected to the battery pack through the second connection terminal 16, reducing the assembly difficulty between the conductive busbar 111 and the battery pack.

[0082] In some embodiments, the second connection terminal 16 is adapted to be detachably connected to the battery pack. Detachably connecting the second connection terminal 16 to the battery pack facilitates future maintenance and replacement.

[0083] In some embodiments, the second connection terminal 16 is integrally formed on the second end of the conductive bus 111, and the conductive bus 111 is adapted to be connected to the battery pack via the second connection terminal 16. That is, the second connection terminal 16 and the conductive bus 111 are integrally formed, which can save the crimping or welding process of the second connection terminal 16. Since the second connection terminal 16 is integrally formed on the second end of the conductive bus 111, the contact resistance caused by crimping or welding can also be reduced, improving the reliability of the electrical connection between the connection device 10 and the battery pack, helping to achieve greater current carrying capacity, and reducing costs.

[0084] For example, the second end of the conductive bus 111 is designed as a second connection terminal 16. That is, the second connection terminal 16 is formed directly on the body of the conductive bus 111, without the need for an additional separate connection terminal, thereby improving the connection reliability between the connection device 10 and the battery pack.

[0085] In some embodiments, please refer to Figure 4 The second end of the conductive busbar 111 is fitted with a second end cap 181 and a protective shell 182. The protective shell 182 is fixedly connected to the conductive busbar 111, and the second end cap 181 is detachably connected to the protective shell 182. The second end cap 181 and the protective shell 182 provide protection for the second end of the conductive busbar 111 and are compatible with the terminals in the battery pack.

[0086] In some embodiments, please refer to Figure 4 The second end of the conductive busbar 111 is also fitted with a fixing panel 184. The fixing panel 184 and the second end cap 181 are respectively disposed on opposite sides of the protective shell 182, and the fixing panel 184 is detachably connected to the protective shell 182. The fixing panel 184, the protective shell 182 and the second end cap 181 can provide protection for the conductive busbar 111 at the second end and ensure connection stability.

[0087] In some embodiments, please refer to Figure 4A second sealing element 183 is provided between the second end cap 181 and the protective shell 182. The second sealing element 183 provided between the second end cap 181 and the protective shell 182 can improve the sealing connection between the second end cap 181 and the protective shell 182, thus achieving a waterproof effect.

[0088] In some embodiments, a second conductive plating layer is provided on the surface of the second connection terminal 16. By providing the second conductive plating layer on the surface of the second connection terminal 16, the electrical connection performance between the busbar 111 and the battery pack can be improved, thereby increasing the current carrying capacity.

[0089] For example, the second conductive coating can be a silver coating. Silver has high conductivity, which can ensure higher electrical transport performance. In addition, the silver coating also has good chemical stability and anti-oxidation properties, which can ensure the stability and reliability of the electrical connection.

[0090] In some embodiments, at least one conductive busbar 111 is a conductive aluminum busbar. By making at least one conductive busbar 111 a conductive aluminum busbar, it is helpful to achieve a lightweight connection device 10, reduce the difficulty of arranging the connection device 10 in the vehicle, and the cost of conductive aluminum busbars is lower than that of conductive copper busbars.

[0091] It is understood that some of the conductive busbars 111 may be conductive aluminum busbars, or all of the conductive busbars 111 may be conductive aluminum busbars. Those skilled in the art can make the settings according to actual needs.

[0092] According to a second aspect of this application, a charging socket assembly is also provided, including a charging socket 20 and a connection device 10 as described above. The connection device 10 is configured to connect between the charging socket 20 and a battery pack.

[0094] In some embodiments, the charging socket assembly further includes a fixing member 30. The fixing member 30 is sleeved around the connecting device 10 and is configured to secure the connecting device 10 to the vehicle. The fixing member 30 can secure the connecting device 10 to other components in the vehicle, improving the stability of the connecting device 10 in the vehicle and reducing the difficulty of installation and the possibility of damage.
