[0042] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 The cooling terminal assembly 100 according to an embodiment of the present invention includes: a first terminal 10 and a heat exchange sleeve 20.

[0043] like Figure 2 As shown, the heat exchange sleeve 20 is fitted onto the first terminal 10, and the heat exchange sleeve 20 contains a heat exchange medium suitable for heat exchange with the first terminal 10.

[0044] The first terminal 10 mates with the heat exchange sleeve 20, and a mating hole is formed inside the heat exchange sleeve 20. At least a portion of the first terminal 10 mates within the mating hole. The heat exchange medium is disposed within the heat exchange sleeve 20 and flows within it. Due to the contact between the first terminal 10 and the heat exchange sleeve 20, heat exchange occurs between the flowing heat exchange medium and the heat exchange sleeve 20 through heat conduction, thereby effectively reducing the temperature generated by the first terminal 10 during operation. In this embodiment, the heat exchange medium can be water or other cooling media, and is not limited thereto.

[0045] According to the embodiment of the present invention, the cooling terminal assembly 100, by fitting a heat exchange sleeve 20 containing a heat exchange medium inside onto the first terminal 10, shortens the distance between the heat exchange medium and the first terminal 10 for heat exchange through the heat exchange sleeve 20, improves the heat dissipation effect of the cooling terminal assembly 100, shortens the cooling time, and simplifies the structure and installation of the cooling terminal assembly 100. At the same time, the heat exchange medium is isolated from the first terminal 10 through the heat exchange sleeve 20, effectively reducing leakage and the safety hazards after leakage, improving the safety and reliability of vehicle use, and the heat exchange medium can be made of inexpensive materials, reducing production costs.

[0046] According to some embodiments of this utility model, such as Figure 2 As shown, the first terminal 10 has a plug-in end 101, and the heat exchange medium is adapted to exchange heat with the plug-in end 101.

[0047] The first terminal 10 has a plug-in end 101 formed at one end adjacent to the heat exchange sleeve 20 along the second direction B. The plug-in end 101 is adapted to mate with the heat exchange sleeve 20. For example, the heat exchange sleeve 20 can be sleeved on the plug-in end 101 along the second direction B. At this time, the heat exchange medium inside the heat exchange sleeve 20 can exchange heat with the plug-in end 101. For example, after the plug-in end 101 mates with the heat exchange sleeve 20, the heat generated by the plug-in end 101 is conducted to the heat exchange medium through the heat exchange sleeve 20. After heat exchange with the heat exchange medium, the heat exchange medium carries away the heat generated by the plug-in end 101, thereby reducing the temperature of the plug-in end 101. In this embodiment, the width direction of the cooling terminal assembly 100 can be the first direction A, and the length direction of the cooling terminal assembly 100 can be the second direction B. The first direction A and the second direction B are perpendicular.

[0048] Therefore, heat exchange occurs between the heat exchange medium and the plug-in end 101. Since the heat exchange medium is positioned adjacent to the plug-in end 101 of the first terminal 10, the heat generated at the plug-in end 101 of the first terminal 10 can be conducted out of the cooling terminal assembly 100 through the heat exchange medium in a timely manner, effectively dissipating heat from the first terminal 10, improving the cooling effect, and shortening the cooling time. Furthermore, integrating the heat exchange medium within the heat exchange sleeve 20 facilitates the miniaturization and integration of the cooling terminal assembly 100.

[0049] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a heat exchange channel 30 is provided inside the heat exchange sleeve 20, and the heat exchange medium is located inside the heat exchange channel 30; at least a portion of the heat exchange channel 30 covers at least a portion of the plug-in end 101.

[0050] A heat exchange sleeve 20 has a heat exchange channel 30 formed inside, which is adapted to provide a heat exchange path for the heat exchange medium. At least a portion of the heat exchange channel 30 is opposite to the insertion end 101 along the thickness direction of the insertion end 101, and at least a portion of the heat exchange sleeve 20 with the heat exchange channel 30 is in contact with the insertion end 101. The fact that at least a portion of the heat exchange channel 30 covers at least one side of the insertion end 101 along its thickness direction can be understood as follows: after the insertion end 101 is engaged with the heat exchange sleeve 20, the portion of the heat exchange sleeve 20 with the heat exchange channel 30 is at least partially opposite to the insertion end 101 along its thickness direction. The portion of the heat exchange sleeve 20 opposite to the insertion end 101 along its thickness direction has the heat exchange channel 30. Optionally, the heat exchange sleeve 20 with heat exchange channel 30 can be completely opposite to the plug-in end 101 along the thickness direction of the plug-in end 101, thereby increasing the setting area of ​​the heat exchange channel 30 and the area opposite to the plug-in end 101, and improving the heat dissipation capacity of the cooling terminal assembly 100.

[0051] Therefore, by setting the heat exchange channel 30, the heat exchange path of the heat exchange medium can be defined, avoiding the heat exchange channel 30 occupying the mating space between the plug-in end 101 and the heat exchange sleeve 20, and preventing interference between the heat exchange channel 30 and the plug-in end 101. This improves the cooling effect while ensuring the working environment of the plug-in end 101. At the same time, the heat exchange capacity between the heat exchange medium and the first terminal 10 can be increased by increasing the area or number of heat exchange channels 30 set in the heat exchange sleeve 20.

[0052] In this embodiment, in order to facilitate the cooperation between the heat exchange sleeve 20 and the plug end 101 and reduce the space occupied on the mating surface of the heat exchange sleeve 20 and the plug end 101, when setting the heat exchange channel 30, at least part of the side wall of the heat exchange channel 30 protrudes from the surface of the heat exchange sleeve 20 away from the plug end 101. This can avoid interference in the assembly of the heat exchange sleeve 20 and the plug end 101, ensure the setting of the heat exchange channel 30, and facilitate the setting of the heat exchange medium in the heat exchange channel 30.

[0053] According to some embodiments of this utility model, such as Figure 3As shown, the heat exchange sleeve 20 includes a sleeve portion 21 and a cover plate portion 22. The sleeve portion 21 is provided with an insertion portion 211, and the insertion end 101 is fitted inside the insertion portion 211. The cover plate portion 22 is provided on the side of the sleeve portion 21 away from the insertion portion 211. The cover plate portion 22 and the sleeve portion 21 together define the heat exchange channel 30.

[0054] The cover plate portion 22 and the sheath portion 21 are aligned and bonded at one end adjacent to the cover plate portion 22 along the second direction B. The sheath portion 21, at the other end away from the cover plate portion 22 along the second direction B, has an insertion portion 211 adapted to mate with the insertion end 101. The insertion end 101 passes through the cover plate portion 22 and the sheath portion 21 sequentially along the second direction B and mates within the insertion portion 211. The heat exchange sheath 20 has mating holes that penetrate the cover plate portion 22 and the sheath portion 21 along the second direction B, and the cross-sectional shape of the mating holes matches the cross-sectional shape of the insertion end 101. The insertion end 101 passes through the mating holes of the cover plate portion 22 and the sheath portion 21 along the second direction B and mates with the insertion portion 211 on the sheath portion 21. The heat exchange channel 30 is formed on the sheath portion 21 and the cover plate portion 22, which reduces the manufacturing difficulty of forming the heat exchange channel 30.

[0055] Therefore, by providing the cover plate portion 22 and the sheath portion 21, the heat exchange medium can flow within the heat exchange channel 30 defined by the cover plate portion 22 and the sheath portion 21. The insertion portion 211 facilitates the placement of the heat exchange channel 30 within the sheath portion 21, which helps to shorten the distance between the heat exchange medium in the heat exchange channel 30 and the insertion end 101, thereby improving heat exchange efficiency. At the same time, since the insertion portion 211 can effectively block open flames and reduce the range of ablation and melting propagation in the event of ablation of the insertion end 101 under extreme conditions, it can also prevent ablation.

[0056] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the heat exchange channel 30 includes: a plurality of first heat exchange channel segments 31 and at least one second heat exchange channel segment 32. The plurality of first heat exchange channel segments 31 are formed between the cover plate portion 22 and the sheath portion 21. The second heat exchange channel segment 32 is connected between two adjacent first heat exchange channel segments 31. The second heat exchange channel segment 32 is located on at least one side of the insertion portion 211 along the thickness direction of the insertion end 101.

[0057] Multiple first heat exchange channel segments 31 are disposed between the cover plate portion 22 and the sheath portion 21 near one end of the cover plate portion 22, with the multiple first heat exchange channel segments 31 spaced apart. A second heat exchange channel segment 32 is disposed between two adjacent first heat exchange channel segments 31 and is respectively connected to the adjacent ends of the two adjacent first heat exchange channel segments 31 along the first direction A. The second heat exchange channel segment 32 is disposed on the side of the insertion portion 211 away from the insertion end 101 along the thickness direction. In this embodiment, at least a portion of the sidewall of the heat exchange channel 30 disposed in the insertion portion 211 protrudes from one side surface of the insertion portion 211 in the thickness direction.

[0058] Therefore, the heat exchange channel 30 is provided with multiple first heat exchange channel sections 31 and at least one second heat exchange channel section 32, which can make full use of the internal space of the heat exchange sleeve 20, increase the flow path of the heat exchange medium in the heat exchange channel 30, facilitate the flow of the heat exchange medium between the cover plate part 22 and the sleeve part 21, and enable the plug end 101 to exchange heat with the heat exchange medium in the heat exchange channel 30 in all directions, thereby improving the heat dissipation efficiency of the plug end 101.

[0059] According to some embodiments of this utility model, such as Figure 3 As shown, heat exchange grooves 23 are formed on the opposing surfaces of the cover plate portion 22 and the sheath portion 21, and the heat exchange grooves 23 of the cover plate portion 22 and the sheath portion 21 together form the first heat exchange channel section 31.

[0060] Multiple heat exchange grooves 23 are formed on the adjacent surfaces of the cover plate portion 22 and the sheath portion 21 along the second direction B. The multiple heat exchange grooves 23 on the cover plate portion 22 and the sheath portion 21 are respectively opposite to each other along the second direction B. The multiple heat exchange grooves 23 on the cover plate portion 22 and the sheath portion 21 are respectively located on the outer periphery of the mating holes on the cover plate portion 22 and the sheath portion 21. The multiple heat exchange grooves 23 on the cover plate portion 22 and the sheath portion 21 together form multiple first heat exchange channel sections 31.

[0061] In this embodiment, the heat exchange pipeline can be installed inside the heat exchange channel 30, and the heat exchange pipeline contains a heat exchange medium.

[0062] Optionally, a heat exchange medium can be directly introduced into the heat exchange channel 30.

[0063] Thus, by forming heat exchange grooves 23 on the opposing surfaces of the plate portion and the sheath portion 21 respectively, and jointly defining the first heat exchange channel section 31, a flow path is defined for the heat exchange medium, reducing the manufacturing difficulty of the heat exchange channel 30 and improving the production efficiency and reliability of the heat exchange channel 30.

[0064] Optionally, in this embodiment, a heat exchange groove 23 may be provided only on the side of the cover plate portion 22 adjacent to the sheath portion 21, forming a first heat exchange channel section 31 after the sheath portion 21 and the cover plate portion 22 are connected.

[0065] According to some embodiments of this utility model, such as Figure 3 As shown, the two ends of the second heat exchange channel section 32 are connected to two adjacent first heat exchange channel sections 31 respectively, and the middle part of the second heat exchange channel section 32 extends in a direction away from the cover plate section 22.

[0066] The second heat exchange channel 30 is disposed within the insertion portion 211. The two ends of the second heat exchange channel segment 32 along the first direction A are respectively connected to the adjacent ends of two adjacent first heat exchange channel segments 31, and the two ends of the second heat exchange channel segment 32 extend obliquely along the second direction B in a direction away from each other. In this embodiment, the projection shape of the second heat exchange channel segment 32 onto the sheath portion 21 along the thickness direction of the insertion end 101 is V-shaped.

[0067] Optionally, the projection shape of the second heat exchange channel section 32 along the thickness direction of the insertion end 101 onto the sheath portion 21 can also be rectangular or other shapes, which can be selectively set according to actual conditions and are not limited here. Thus, by setting the second heat exchange channel section 32, the contact area between the heat exchange channel 30 and the heat exchange sheath 20 can be increased, thereby increasing the flow path of the heat exchange medium, effectively improving the heat transfer efficiency, improving the cooling effect of the heat exchange sheath 20, and improving the heat dissipation efficiency of the insertion end 101.

[0068] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the heat exchange sleeve 20 is provided with a heat exchange channel 30, and the heat exchange medium is located in the heat exchange channel 30; there are multiple first terminals 10, and the multiple first terminals 10 are arranged sequentially along the first direction A, that is, the width direction of the cooling terminal assembly 100, and the heat exchange channel 30 surrounds the outer periphery of the multiple first terminals 10.

[0069] For example, multiple first terminals 10 are respectively arranged at intervals along the first direction A, the sheath 21 includes multiple mating parts 211, the plug ends 101 of the multiple first terminals 10 respectively cooperate with the multiple mating parts 211, the heat exchange channel 30 is disposed inside the heat exchange sheath 20, and after the plug end 101 and the mating part 211 are mated, the heat exchange channel 30 surrounds the outer periphery of the plug end 101.

[0070] Therefore, the heat exchange channel 30 is arranged around the outer periphery of the plurality of first terminals 10, which can enable the heat exchange medium in the heat exchange channel 30 to exchange heat with the plug-in ends 101 of the plurality of first terminals 10, improve the heat dissipation efficiency of the plug-in ends 101 of the plurality of first terminals 10, improve the reliability of the connection between the plurality of first terminals 10 and the heat exchange sleeve 20, and improve the overall structural strength and stability of the cooling terminal assembly 100.

[0071] Furthermore, such as Figure 2As shown, the plurality of first terminals 10 include at least one first sub-terminal 11 and at least one second sub-terminal 12, and at least a portion of the heat exchange channel 30 covers at least a portion of the first sub-terminal 11.

[0072] The first sub-terminal 11 and the second sub-terminal 12 are spaced apart along the first direction A. The second heat exchange channel segment 32 in the heat exchange channel 30 is spaced apart from the insertion end 101 of the first sub-terminal 11 along at least one side of the thickness direction of the insertion end 101. That is, the heat exchange channel 30 is located on one or both sides of the insertion end 101 along the thickness direction of the insertion end 101.

[0073] In this embodiment, the plurality of first terminals 10 include two first sub-terminals 11 and one second sub-terminal 12, with the second sub-terminal 12 disposed between the two first sub-terminals 11. There are multiple second heat exchange channel segments 32, each of which is fitted into the insertion end 101 of the first sub-terminal 11. Each second heat exchange channel segment 32 connects to two adjacent first heat exchange channel segments 31. The insertion end 101 of the first sub-terminal 11 includes two sub-insertion ends 111, which are spaced apart along the thickness direction of the insertion end 101. The mating portion 211 includes two first mating portions 212 and one second mating portion 213. The two first mating portions 212 are respectively adapted to the insertion ends 101 of the two first sub-terminals 11, and the second mating portion 213 is adapted to the insertion end 101 of the second sub-terminal 12. Each first mating part 212 includes two sub-matting parts 211. The two sub-plug ends 111 of the first sub-terminal 11 are disposed between the two sub-matting parts 211 and abut against each other with the corresponding sub-matting parts 211. A conductive connector is provided between the two sub-plug ends 111. The conductive connector is suitable for electrical connection with the male connector 200.

[0074] Therefore, the heat exchange medium in the second heat exchange channel section 32 of the heat exchange channel 30 can exchange heat with the plug-in end 101 of the first sub-terminal 11, increasing the coverage area of ​​the heat exchange channel 30, thereby improving the heat dissipation efficiency of the plug-in ends 101 of the multiple first terminals 10 and improving the cooling effect.

[0076] A sealing groove is located on the outer periphery of the heat exchange channel 30, and a sealing substance is provided inside the sealing groove. In this embodiment, the sealing substance can be sealant. Therefore, by setting a sealing groove and providing a sealing substance inside the sealing groove, leakage of the heat exchange medium in the heat exchange channel 30 can be avoided, short circuits can be prevented, and the sealing performance of the heat exchange channel 30 can be improved, thereby improving the safety and reliability of the connector.

Both the heat exchange medium inlet 24 and the heat exchange medium outlet 25 are connected to the heat exchange channel 30. The heat exchange medium inlet 24 and the heat exchange medium outlet 25 are located on the same side of the heat exchange sleeve 20. A temperature sensor 26 is provided on the other side of the heat exchange sleeve 20.

[0078] In this embodiment, the heat exchange medium inlet 24 and the heat exchange medium outlet 25 are spaced apart along the thickness direction of the insertion end 101. The heat exchange medium inlet 24 and the heat exchange medium outlet 25 are located on the cover plate portion 22 and are respectively connected to the adjacent second heat exchange channel section 32 so that the heat exchange medium can circulate within the heat exchange sleeve 20. The heat exchange medium inlet 24 and the heat exchange medium outlet 25 are located on the same side of the heat exchange sleeve 20 along the first direction A. The heat exchange medium enters the heat exchange channel 30 through the heat exchange medium inlet 24, exchanges heat with the first terminal 10, and then flows out from the heat exchange medium outlet 25.

[0079] A temperature sensor 26 is provided on the other side of the heat exchange sleeve 20 along the first direction A. The temperature sensor 26 is adapted to detect the temperature of the cooling terminal assembly 100 in real time. In this embodiment, the temperature sensor 26 is connected to the heat exchange sleeve 20 through point thermally conductive silicone to improve thermal conductivity and thus increase sensitivity. Preferably, the temperature sensor 26 abuts against the plug-in end 101.

[0080] Therefore, by setting up a heat exchange medium inlet 24 and a heat exchange medium outlet 25, a complete heat exchange circuit is provided for the heat exchange medium. The temperature sensor 26 is set up to facilitate accurate detection of the temperature of the cooling terminal assembly 100, thereby achieving precise heat dissipation of the first terminal 10 and improving the reliability and safety of the cooling terminal assembly 100.

The first channel section 311 and the second channel section 312 are spaced apart on both sides of the second sub-terminal 12 along the thickness direction of the insertion end 101. The two ends of the third channel section 313 are respectively opposite to and spaced apart from the first channel section 311 and the second channel section 312 along the first direction A. The plurality of second heat exchange channel sections 32 include a fourth channel section 321, a fifth channel section, a sixth channel section 322, and a seventh channel section respectively disposed on both sides of the two first sub-terminals 11.

[0082] Combination Figure 3 and Figure 4 In this embodiment, the fourth channel segment 321 connects the heat exchange medium inlet 24 and the first channel segment 311; the sixth channel segment 322 connects the first channel segment 311 and one end of the third channel segment 313; the seventh channel segment connects the other end of the third channel segment 313 and the second channel segment 312; and the fifth channel segment connects the second channel segment 312 and the heat exchange medium outlet 25. The heat exchange medium entering the heat exchange channel 30 flows out from the heat exchange medium outlet 25 after passing through the heat exchange medium inlet 24, the fourth channel segment 321, the first channel segment 311, the sixth channel segment 322, the third channel segment 313, the seventh channel segment, the second channel segment 312, and the fifth channel segment in sequence.

[0083] Optionally, a sealing groove is provided on the outer periphery of the heat exchange medium inlet 24 and the heat exchange medium outlet 25, and a sealing material is provided in the sealing groove.

[0084] Furthermore, the heat exchange sleeve 20 is made of ceramic. Therefore, the heat dissipation capacity of the heat exchange sleeve 20 can be further improved by using a highly thermally conductive ceramic component, thereby increasing the heat dissipation efficiency of the first terminal 10. In extreme cases, when the plug-in end 101 is ablated, the ablation and melting cannot spread further, improving insulation, preventing short circuits, and enhancing the safety and reliability of use.

[0085] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the cooling terminal assembly 100 further includes a sheath 40, which is sleeved outside the heat exchange sheath 20.

[0086] Sheaths 40 are respectively disposed at both ends of the heat exchange sheath 20 along the second direction B. After the plurality of first terminals 10 are engaged with the heat exchange sheath 20 along the second direction B, the sheaths 40 can be fixed to both ends of the heat exchange sheath 20 along the second direction B by fasteners. In this embodiment, the fasteners can be bolts or screws.

[0087] Therefore, by providing the sheath 40, the first terminal 10 and the heat exchange sheath 20 can be protected, preventing the first terminal 10 and the heat exchange sheath 20 from interfering with other components, thereby improving the structural strength and stability of the cooling terminal assembly 100.

[0088] Furthermore, the sheath 40 is made of plastic. This effectively reduces the production cost of the sheath 40, lightens the weight of the cooling terminal assembly 100, and achieves a lightweight design for the cooling terminal assembly 100.

[0090] According to the connector assembly 1 of the third aspect embodiment of the present utility model, in conjunction with Figure 1 The connector assembly 1 includes a male connector 200 and a female connector, wherein the female connector is the female connector of the second aspect embodiment described above; the male connector 200 is adapted to be inserted and mated with the female connector.

[0091] In this embodiment, the insertion end 101 of the first terminal 10 in the female connector forms an insertion engagement with the male connector 200 along the second direction B. The male connector 200 can connect to a cable, thereby enabling the transmission of current through the multiple first sub-terminals 11 in the first terminal 10. At least one second sub-terminal 12 in the first terminal 10 can provide heating for the connector assembly 1 in extremely cold conditions, ensuring the normal use of the connector assembly 1.
