Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0043] The following is combined Figures 1-6 The liquid-cooled connector of the present invention is described.

[0044] like Figure 4 As shown, the liquid-cooled connector in this embodiment of the invention mainly includes a contact body 1 and a sleeve 2. The contact body 1 is used to connect the end of a cable, and an insulating layer is provided on the surface of the contact body 1. The sleeve 2 is sleeved on the outside of the contact body 1, and a liquid-cooling cavity 3 is formed between the inner side wall of the sleeve 2 and the outer side wall of the insulating layer. The surface of the sleeve 2 is provided with an inlet 4 and an outlet 5 that communicate with the liquid-cooling cavity 3. The inlet 4 is connected to a first pipe 21, which is suitable for connecting to a water-cooled unit. The water-cooled unit is suitable for connecting to the outlet 5 through a second pipe 22.

[0045] In this embodiment, circuit continuity is achieved by connecting the cable end to the contact body 1. A sleeve 2 is fitted over the contact body 1, and a liquid-cooled cavity 3 is formed between the insulating layer on the surface of the contact body 1 and the sleeve 2. A water-cooling unit and the first pipeline 21 provide coolant to the liquid-cooled cavity 3. The coolant, upon contacting the contact body 1 within the liquid-cooled cavity 3, carries away the Joule heat generated by the contact body 1, thereby cooling it. Because an insulating layer is provided on the surface of the contact body 1, problems such as short circuits caused by water contact can be avoided. This method prevents thermal failure, leakage, and fire hazards caused by the contact body 1's inability to dissipate heat, ensuring the safe use of the connector.

[0046] Compared to traditional high-current connectors, liquid-cooled connectors using the above method have significantly lower operating temperatures and longer component lifespans. Furthermore, the liquid-cooled connector has a simple structure, adds almost no extra volume, and has minimal impact on space occupancy.

[0047] Understandably, the water-cooled unit provides coolant, which enters the liquid-cooled chamber 3 through the first pipe 21. After the coolant flows over the surface of the contact body 1, it can carry away the heat of the contact body 1 and reduce the working temperature of the contact body 1. After the coolant is discharged from the outlet 5 through the outlet pipe, it can carry away the heat from the contact body 1, thus realizing the heat dissipation of the contact body 1.

[0048] To ensure effective liquid cooling, the inlet 4 and outlet 5 are located on opposite sides of the sleeve 2, so that after the coolant enters the liquid cooling chamber 3 through the inlet 4, the coolant can at least cover half of the outer surface of the contact body 1. Specifically, the inlet 4 can be located on the upper surface of the sleeve 2, in which case the outlet 5 can be located on the lower surface of the sleeve 2. Alternatively, the inlet 4 can be located on the lower surface of the sleeve 2, in which case the outlet 5 can be located on the upper surface of the sleeve 2. That is, the coolant can enter from the top and exit from the bottom, or vice versa; the bottom-in, top-out method is preferred to ensure that the liquid cooling chamber 3 is filled with coolant. Of course, other entry and exit methods can also be used for the coolant, which will not be elaborated here.

[0049] The coolant can be tap water, ethylene glycol, or other environmentally friendly refrigerants.

[0050] Water-cooled units can recycle and reuse cooling water, thus achieving resource reuse.

[0051] Sleeve 2 is an insulating sleeve, for example, sleeve 2 can be made of rubber. The insulating layer provided on the surface of contact body 1 can also be made of rubber.

[0052] like Figure 4 and Figure 5 As shown, the inner wall of the sleeve 2 is constructed with a first annular groove 6, and the outer wall of the contact body 1 is constructed with a second annular groove 7. The positions of the first annular groove 6 and the second annular groove 7 are corresponding, and the area between the first annular groove 6 and the second annular groove 7 forms a liquid cooling cavity 3.

[0053] The first annular groove 6 is recessed into the inner wall of the sleeve 2, and the second annular groove 7 is recessed into the outer wall of the contact body 1. The first annular groove 6 and the second annular groove 7 are arranged opposite to each other so that the grooves of the first annular groove 6 and the second annular groove 7 are connected to form a liquid cooling cavity 3.

[0054] Correspondingly, both the inlet 4 and the outlet 5 have areas on the sleeve 2 that correspond to the first annular groove 6.

[0055] like Figure 5 As shown, the second annular groove 7 is provided with heat dissipation fins 8. The heat dissipation fins 8 can increase the heat exchange area between the coolant and the contact body 1, thereby accelerating heat dissipation and ensuring heat exchange efficiency. Multiple heat dissipation fins 8 are provided to further increase the heat exchange area and improve the heat dissipation speed.

[0056] According to the liquid-cooled connector provided by the present invention, the water-cooled unit includes a water storage tank and a pump. The pump is connected to the outlet of the water storage tank and is adapted to be connected to the inlet 4 via a first pipe 21, and a second pipe 22 is connected to the inlet of the water storage tank. The pump, the first pipe 21, the second pipe 22, the liquid-cooled unit, and the water storage tank form a water flow loop to achieve water circulation-type heat dissipation and cooling. The pump provides the power to deliver water and ensures the flow of coolant. Water-sealed connections are used between the pump and the water storage tank, between the first pipe 21 and the pump, between the first pipe 21 and the inlet 4, between the outlet 5 and the second pipe 22, and between the second pipe 22 and the water storage tank to prevent coolant leakage from the connections.

[0057] The water tank serves as the storage unit for the coolant, with its inlet located at the top and its outlet at the bottom to facilitate coolant discharge and recycling. A filter assembly can be installed within the water tank to remove particulate impurities from the coolant, ensuring its cleanliness and preventing coolant containing particulate impurities from damaging the insulation layer in the liquid cooling chamber 3, which could lead to electrical leakage or other hazards.

[0058] At least one of the water storage tank, the first pipe 21, and the second pipe 22 is equipped with a heat dissipation component. That is, a heat dissipation component can be installed in only the water storage tank, the first pipe 21, and the second pipe 22, or in two of the water storage tank, the first pipe 21, and the second pipe 22, or in both of the water storage tank, the first pipe 21, and the second pipe 22. The heat dissipation component dissipates heat from the coolant, ensuring that the temperature of the coolant entering the liquid cooling chamber 3 remains low, thus achieving a good cooling effect.

[0059] The heat dissipation component can include a radiator and a fan. After the coolant flows into the radiator, the fan blows away the heat, thereby cooling the coolant. The fan model can be selected according to the coolant temperature and flow rate. A power control system can be added to the fan, which can then adjust the appropriate airflow based on the connector's operating temperature, ensuring cooling performance while achieving energy savings.

[0060] like Figure 1 and Figure 2 As shown, the liquid-cooled connector in this embodiment of the invention also includes a housing 9, and a sleeve 2 is adapted to be fixed inside the housing 9 by a connecting mechanism. The housing 9 has clearance holes on opposite sides, and the first pipe 21 and the second pipe 22 pass through the two clearance holes respectively and are fixed to the housing 9 by a locking mechanism.

[0061] The sleeve 2 and the connector can be fixed and protected by the housing 9, which is hollow inside to facilitate the placement of the sleeve 2. Figure 1As shown, openings are formed on the left and right sides of the outer casing 9 to allow the ends of the cable to pass through the inner casing 9 from both ends, thereby connecting with the two ends of the contact body 1. Clearance holes are formed on the upper and lower sides of the outer casing 9 to allow the first conduit 21 and the second conduit 22 to pass through, respectively.

[0062] like Figure 1 As shown, the upper and lower sides of the outer casing 9 are provided with inclined surfaces, which are close to each other and inclined, with clearance holes respectively provided on the two inclined surfaces. This shape design facilitates the avoidance of other parts during the installation of the outer casing 9, and makes it easier to install and fix the outer casing 9.

[0063] In this embodiment, the locking mechanism includes an annular connecting portion 10 and a locking portion 12. The annular connecting portion 10 is fixed to the outside of the housing 9. A portion of the annular connecting portion 10 away from the housing 9 extends a connector 11 in a direction away from the annular connecting portion 10. The locking portion 12 is adapted to be connected to the connector 11 via a locking element. The first conduit 21 and the second conduit 22 respectively pass through the two annular connecting portions 10. The locking portion 12 and the connector 11 form an annular structure to lock the first conduit 21 or the second conduit 22.

[0064] like Figure 1 As shown, one end of the first pipe 21 is connected to the water inlet 4, and the other end passes through the relief hole. The first pipe 21 or the second pipe 22 is locked from the position of the relief hole by a locking mechanism to fix the position of the first pipe 21 and the second pipe 22.

[0065] Understandably, the central portion of the annular connecting part 10 forms an opening, the shape and size of which are the same as those of the first pipe 21 and the second pipe 22. When the first pipe 21 and the second pipe 22 are round pipes, the opening is round; when the first pipe 21 and the second pipe 22 are square pipes, the opening is square. This ensures that the first pipe 21 and the second pipe 22 can pass through the annular connecting part 10.

[0066] A portion of the annular connecting part 10 extends from the side away from the outer casing 9 to form a connector 11 for connecting the locking part 12. After the locking part 12 and the connector 11 are closed and connected, they can form the same shape as the annular connecting part 10, thereby enclosing the first pipe 21 and the second pipe 22. With the help of fasteners, a tight connection is formed between the locking part and the connector 11 to securely clamp the first pipe 21 and the second pipe 22.

[0067] like Figure 6 As shown, the connector 11 is integrally formed on the side of the annular connecting part 10 away from the outer shell 9. The connector 11 is set as a semi-circular annular structure. Correspondingly, the locking member is also set as a semi-circular annular structure. When the connector 11 and the locking member are connected, they can form an annular structure, thereby clamping and fixing the first pipe 21 and the second pipe 22.

[0068] The connector 11 is provided with a first locking hole 13, and the locking part 12 is provided with a second locking hole 14. The first locking hole 13 and the second locking hole 14 are adapted to each other, and the first locking hole 13 and the second locking hole 14 are adapted to be fixed together by a fastener. For example, the fastener is a bolt.

[0069] It is understood that the first locking hole 13 on the connector 11 and the second locking hole 14 on the locking part 12 are positioned correspondingly and are the same size. When the locking part 12 is connected to the connector 11, the first locking hole 13 and the second locking hole 14 are aligned, and fasteners are inserted into the first locking hole 13 and the second locking hole 14 to achieve a secure fixation between the connector 11 and the locking part 12.

[0070] To ensure the fastener is properly inserted, both the first locking hole 13 and the second locking hole 14 are through round holes.

[0071] like Figure 6 As shown, the outer peripheral surface of the annular connecting portion 10 is provided with a connecting lug 15, the connecting lug 15 is provided with a connecting hole 16, and the surface of the housing 9 is constructed with a mounting hole. The connecting hole 16 and the mounting hole are adapted to be connected by a fastener. For example, the fastener is a screw.

[0072] By providing a connecting lug 15 on the outer peripheral surface of the annular connecting portion 10, and using fasteners passing through the connecting hole 16 and the mounting hole, the position of the annular connecting portion 10 is fixed. This method also allows the annular connecting portion 10 to be detachably connected to the housing 9, facilitating maintenance and replacement of the annular connecting portion 10.

[0073] Multiple connecting ears 15 are provided at intervals on the outer peripheral surface of the annular connecting part 10. Correspondingly, multiple mounting holes are arranged in a ring on the surface of the housing 9. The multiple connecting ears 15 are connected to the multiple mounting holes to achieve a reliable connection of the annular connecting part 10.

[0074] According to the liquid-cooled connector provided by the present invention, the connection mechanism includes a connecting post 17, an adapter 18, a connector 19, and a fixing plate 20. The connecting post 17 is disposed on the inner side wall of the housing 9. The adapter 18 is connected to the connecting post 17 by fasteners. The connector 19 is connected to the adapter 18. The fixing plate 20 is provided with a socket hole and is adapted to be sleeved on the outside of the sleeve 2 through the socket hole. The fixing plate 20 and the connector 19 are adapted to be connected by fasteners. For example, the fastener is a screw.

[0075] like Figure 2As shown, the connecting post 17 can be arranged along the length of the outer shell 9, and a threaded hole is provided on the side of the connecting post 17 facing the adapter 18. The adapter 18 is L-shaped, and a through hole is provided on the side of the adapter 18 that connects to the connecting post 17, so that the through hole and the threaded hole are connected by fasteners to achieve a reliable connection between the adapter 18 and the connecting post 17. The other end of the adapter 18 is bent downward and connected to the connecting plate. The connecting plate is connected to the fixing plate 20 by fasteners. Then, the fixing plate 20 is sleeved on the outside of the sleeve 2 through the socket hole to achieve the connection between the two, so as to fix the sleeve 2 inside the outer shell 9.

[0076] L-shaped adapter 18 is suitable for integral molding with connector 19.

[0077] The connector 19 can be elongated and vertically installed inside the outer casing 9. Adapters 18 are integrally formed on both the upper and lower sides of the connector 19. Alternatively, two connectors 19 can be used, located on opposite sides of the sleeve 2. In this case, two connecting posts 17 are provided on each side of the sleeve 2 on the inner wall of the outer casing 9, connecting the various adapters 18. This arrangement allows for multi-point connection and fixation, making the sleeve 2 more securely positioned.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
