[0043] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0044] In some embodiments, refer to Figures 1 to 4 As shown, this application provides a terminal structure, including: a heat-conducting shell 1 and a terminal 2. The heat-conducting shell 1 has a cooling circulation pipe 3 for circulating a cooling medium. The terminal 2 includes a main body 4, a plug-in portion 5, and a wiring portion 6. The main body 4 passes through the heat-conducting shell 1, the plug-in portion 5 is connected to one end of the main body 4, and the wiring portion 6 is connected to the end of the main body 4 away from the plug-in portion 5 and extends outside the heat-conducting shell 1.

[0045] Specifically, the type of the heat-conducting shell 1 is not particularly limited, as long as it can conduct heat. For example, it can be a metal shell, and materials with high thermal conductivity (such as aluminum, copper, or aluminum alloys) can be further selected to improve heat dissipation. The heat-conducting shell 1 is internally designed with cooling circulation pipes 3 for circulating cooling media (such as water, oil, or other suitable liquids or gases). The main purpose of this design is to remove the heat generated by the terminal 2 through the cooling medium, thereby reducing the operating temperature of the terminal 2.

[0046] Terminal 2 can be a one-piece molded structure, comprising three main parts: a main body 4, a connector 5, and a wiring part 6. The main body 4 penetrates the interior of the heat-conducting shell 1, directly contacting the inner wall of the heat-conducting shell 1, facilitating rapid heat conduction to the heat-conducting shell 1 and heat dissipation through the cooling circulation pipe 3. The connector 5 is connected to one end of the main body 4 for connection with other compatible terminals 2, ensuring the stability of the electrical connection. Terminal 2 can be a male or female terminal, and the connector 5 can be located inside or outside the heat-conducting shell 1, such as... Figure 2 and Figure 5 As shown, when terminal 2 is a male terminal, the insertion part 5 can be a pin and extends outside the heat-conducting shell 1; as Figure 3 and Figure 6 As shown, when terminal 2 is a female terminal, the plug-in part 5 may include multiple spring pieces 7 disposed in the heat-conducting shell 1, and surround the plug cavity 8; when the male terminal is mated with the female terminal, the pin is inserted into the plug cavity to realize electrical connection. The wiring part 6 is disposed at the end of the main body part 4 away from the plug-in part 5 and extends to the outside of the heat-conducting shell 1, and the wiring part 6 may be provided with wiring holes 9 to facilitate the connection of external wires.

[0047] It is understood that the terminal structure in this embodiment mainly utilizes the cooling circulation pipes 3 within the heat-conducting shell 1 to achieve efficient heat dissipation. The specific workflow includes: when current flows through the terminal 2, heat is generated due to the resistance effect, and the main body 4 of the terminal 2 conducts the heat to the heat-conducting shell 1 surrounding it. Since the heat-conducting shell 1 contains cooling circulation pipes 3, the cooling medium absorbs heat as it flows through these pipes, then carries the heat away from the terminal 2 area, completing the cooling cycle. This design effectively reduces the operating temperature of the terminal 2, improves its overcurrent capability, reduces the risk of performance degradation or damage due to high temperatures, and thus extends its service life.

[0048] Therefore, the terminal structure provided in this application, by introducing the cooling circulation pipe 3, can significantly improve the heat dissipation efficiency of the terminal 2, reduce overheating problems caused by prolonged use, and enhance the stability and durability of the terminal 2. This is particularly important for electrical connection scenarios requiring high reliability, such as high-voltage power systems and industrial automation equipment.

[0049] In some embodiments, refer to Figure 4 As shown, the cooling circulation pipe 3 is arranged around the main body 4.

[0050] Specifically, the design of the cooling circulation pipe 3 surrounding the main body 4 can provide... Figure 4 The frame structure shown can also be a spiral structure. The surrounding cooling circulation pipes 3 ensure that heat is quickly and evenly absorbed and dissipated from all directions of the main body 4. This layout ensures uniform and efficient heat dissipation even under high current load conditions, avoiding the formation of localized hot spots.

[0051] In one embodiment, refer to Figure 2 and Figure 4 As shown, the heat-conducting shell 1 is provided with a cooling medium inlet 10 and a cooling medium outlet 11; the cooling circulation pipe 3 includes: a first layer pipe structure 12, a second layer pipe structure 13 and a transition pipe 14. The first-layer pipe structure 12 includes a first pipe 15, a second pipe 16, and a third pipe 17 located on one side of the main body 4 and connected end to end. The first pipe 15 and the third pipe 17 span the main body 4 and have an angle with the second pipe 16. The end of the first pipe 15 away from the second pipe 16 is connected to the cooling medium inlet 10. The second-layer pipe structure 13 includes a fourth pipe 18, a fifth pipe 19, and a sixth pipe 20 located on the other side of the main body 4 opposite to the first-layer pipe structure 12 and connected end to end. The fourth pipe 18 and the sixth pipe 20 span the main body 4 and have an angle with the fifth pipe 19. The end of the sixth pipe 20 away from the fifth pipe 19 is connected to the cooling medium outlet 11. One end of the transition pipe 14 is connected to the end of the third pipe 17 away from the second pipe 16, and the other end of the transition pipe 14 is connected to the end of the fourth pipe 18 away from the fifth pipe 19.

[0052] Specifically, the first-layer pipe structure 12 can be disposed on the upper side of the main body 4 of the terminal 2. One end of the first pipe 15 can be connected to the cooling medium inlet 10 of the heat-conducting shell 1 through the seventh pipe 21 to facilitate the introduction of cooling medium. One end of the second pipe 16 is connected to the other end of the first pipe 15, forming a certain angle. One end of the third pipe 17 is connected to the other end of the second pipe 16, also forming a certain angle, and the other end of the third pipe 17 is connected to one end of the transition pipe 14. For example, the second pipe 16 extends along the axial direction of the terminal 2, and the first pipe 15 and the third pipe 17 are both perpendicularly connected to the two ends of the second pipe 16 along the radial direction of the terminal 2. The seventh pipe 21 is arranged parallel to the second pipe 16.

[0053] The second-layer pipe structure 13 can be disposed on the lower side of the main body 4 of the terminal 2. One end of the fourth pipe 18 is connected to the other end of the transition pipe 14; one end of the fifth pipe 19 is connected to the other end of the fourth pipe 18, forming a certain angle. One end of the sixth pipe 20 is connected to the other end of the fifth pipe 19, also forming a certain angle. The other end of the sixth pipe 20 can be connected to the cooling medium outlet 11 of the heat-conducting shell 1 through the eighth pipe 22, so as to discharge the cooled medium after heat exchange to the outside of the heat-conducting shell 1. For example, the fifth pipe 19 extends along the axial direction of the terminal 2, and the fourth pipe 18 and the sixth pipe 20 are both perpendicularly connected to the two ends of the fifth pipe 19 along the radial direction of the terminal 2. The eighth pipe 22 is arranged parallel to the fifth pipe 19.

[0054] Furthermore, the first layer pipe structure 12 and the second layer pipe structure 13 can be symmetrically arranged on the upper and lower sides of the main body 4 of the terminal 2, simplifying the structural design and facilitating processing.

[0055] The transition pipe 14 can be vertically connected between the third pipe 17 in the first layer pipe structure 12 and the fourth pipe 18 in the second layer pipe structure 13, realizing a loop connection between the upper and lower pipe structures.

[0056] During operation, the cooling medium first enters the first-layer pipe structure 12 through the cooling medium inlet 10 and the seventh pipe 21. It then flows along a predetermined path (first pipe 15 to second pipe 16 to third pipe 17), absorbing heat generated by the terminal 2. Next, through the transition pipe 14, the cooling medium continues to flow into the second-layer pipe structure 13, continuing to absorb heat along a predetermined path (fourth pipe 18 to fifth pipe 19 to sixth pipe 20 to eighth pipe 22). Finally, the cooled medium, after heat exchange, is discharged outside the heat-conducting shell 1 through the cooling medium outlet 11.

[0057] Understandably, the angled arrangement between the pipes in this application allows for a more tortuous flow path of the cooling medium within the pipes, ensuring that the cooling medium can cover a larger heat dissipation area, thereby improving heat dissipation efficiency. The angle can be adjusted according to specific application requirements, for example, to 80°, 85°, 90°, 95°, etc. Furthermore, the double-layer pipe frame structure allows the cooling medium to cool the heat-conducting shell 1 from multiple directions, avoiding the formation of localized hot spots and ensuring uniform temperature distribution. The circulation design of the upper and lower pipe structures ensures that the cooling medium can flow fully throughout the entire pipe, maximizing heat removal and improving overall heat exchange efficiency.

[0058] Therefore, the multi-layered and multi-angled pipe layout of this embodiment not only optimizes the flow path of the cooling medium, but also greatly improves the heat transfer efficiency, enhances the heat dissipation capacity of terminal 2, and effectively solves the overheating problem that occurs during long-term use of terminal 2.

[0059] In one embodiment, the cooling circulation pipe 3 is spiral in shape and spirals around the main body 4.

[0060] Specifically, the cooling circulation pipe 3 is spirally wound around the main body 4 of the terminal 2, and both ends of the cooling circulation pipe 3 are connected to the cooling medium inlet 10 and the cooling medium outlet 11 of the heat-conducting shell 1 to facilitate the introduction and discharge of the cooling medium. During operation, the cooling medium enters the spiral cooling circulation pipe 3 from the cooling medium inlet 10 of the heat-conducting shell 1. As the cooling medium flows along the spiral path, it absorbs heat dissipated from all directions from the main body 4 of the terminal 2. Finally, the cooling medium, after sufficient heat exchange, is discharged from the cooling medium outlet 11 of the heat-conducting shell 1.

[0061] Understandably, since the spiral pipe covers multiple directions of the main body 4, it can absorb heat from all angles, thereby achieving uniform and efficient heat dissipation and significantly improving the heat dissipation and cooling capacity of the terminal 2.

[0062] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 As shown, the terminal structure also includes: a first connector 23 and a second connector 24. The first connector 23 is disposed on the heat-conducting shell 1 and connected to one end of the cooling circulation pipe 3; the second connector 24 is disposed on the heat-conducting shell 1 and connected to the other end of the cooling circulation pipe 3.

[0063] Specifically, the first connector 23 is connected to the seventh pipe 21 via the cooling medium inlet 10 of the heat-conducting shell 1, for introducing cooling medium. The second connector 24 is connected to the eighth pipe 22 via the cooling medium outlet 11 of the heat-conducting shell 1, for discharging the cooled medium after heat exchange. Furthermore, the first connector 23 and the second connector 24 can be connected to an external cooling medium supply system (not shown in the figure). The cooling medium supply system is mainly used to provide circulating cooling medium. The cooling medium enters the cooling circulation pipe 3 through the first connector 23, absorbs the heat generated by the terminal 2, and then flows back to the cooling medium supply system through the second connector 24, ensuring a continuous supply of low-temperature cooling medium, thereby guaranteeing the heat dissipation and cooling effect of the terminal 2.

[0064] The embodiments of this application, through the design of the first connector 23 and the second connector 24, allow for the selection of different types of cooling medium supply systems according to actual needs, adapting to different application scenarios and environmental conditions.

[0065] In some embodiments, the cooling medium supply system includes a heat sink, a pump, and a fan; a first connector 23 and a second connector 24 are used to connect to the heat sink via a delivery pipeline, the delivery pipeline is equipped with a pump, the heat sink is equipped with a cooling medium, and the heat sink is equipped with fans arranged side by side.

[0066] Specifically, the heat sink is used to store and cool the cooling medium, and heat dissipation fins can be installed on the side walls of the heat sink to increase the heat dissipation area and help the heat sink dissipate heat more effectively. A pump located in the delivery pipeline is responsible for driving the cooling medium to flow within the pipeline, ensuring continuous circulation of the cooling medium. Fans are arranged side-by-side next to the heat sink, accelerating the heat dissipation effect of the heat dissipation fins through forced convection, further improving cooling efficiency.

[0067] During operation, a pump draws the cooling medium from the heat sink through the first connector 23 into the cooling circulation pipe 3 of the terminal structure. After absorbing the heat generated by the terminal 2, the medium is discharged back into the heat sink through the second connector 24. Inside the heat sink, the cooling medium transfers heat to the surrounding air through the heat dissipation fins. A fan accelerates airflow through forced convection, helping the heat dissipation fins dissipate heat more effectively. The cooled medium is then pumped back into the cooling circulation pipe 3, completing the cooling cycle.

[0068] Therefore, this design in the embodiments of this application not only improves the heat dissipation efficiency of terminal 2, but also enhances stability and reliability.

[0069] In some embodiments, a heat-conducting layer (not shown) is provided between the main body 4 and the inner wall of the heat-conducting shell 1.

[0070] Specifically, such as Figure 2 As shown, the heat-conducting shell 1 is provided with an installation channel 25, the main body 4 of the terminal 2 passes through the installation channel 25, and a heat-conducting layer is provided between the main body 4 and the inner wall of the installation channel 25. The specific type of the heat-conducting layer is not particularly limited, such as thermal grease, thermal gel, thermal tape, thermal pad, etc.

[0071] The heat-conducting layer can fill the gap between the main body 4 and the inner wall of the heat-conducting shell 1, which can compensate for processing errors to a certain extent, increase the actual contact area between the main body 4 and the heat-conducting shell 1, and thus improve the heat transfer efficiency.

[0072] Therefore, by introducing a heat-conducting layer, the present application embodiment can significantly improve the efficiency of heat transfer from terminal 2 to heat-conducting shell 1, and further enhance the heat dissipation effect of the entire structure.

[0073] In some embodiments, refer to Figure 1 and Figure 2 As shown, the terminal structure also includes a kit 26, which is connected to the heat-conducting shell 1 and fitted onto the plug-in portion 5.

[0074] Specifically, the kit 26 can protect the insertion part 5 of the terminal 2 and facilitate the positioning and docking of the terminal 2.

[0075] like Figure 2 and Figure 5 As shown, when terminal 2 is a male terminal, the insertion part 5 can be a pin, and the sleeve 26 is spaced around the outside of the pin; as Figure 3 and Figure 6As shown, when terminal 2 is a female terminal, the plug-in part 5 may include a plurality of spring pieces 7 disposed in the heat-conducting shell 1 and surround the plug cavity 8. The kit 26 is sleeved on the outside of the plurality of spring pieces 7 and has a gap between it and the heat-conducting shell 1. When the male terminal is connected to the female terminal, the kit 26 of the male terminal is inserted into the gap between the kit 26 of the female terminal and the heat-conducting shell 1, and the kit 26 of the female terminal is inserted into the gap between the kit 26 of the male terminal and the pin. At the same time, the pin is inserted into the plug cavity to achieve positioning connection.

[0076] In some embodiments, refer to Figure 1 and Figure 2 As shown, kit 26 and heat-conducting shell 1 are integrally molded structures.

[0077] Specifically, kit 26 and heat-conducting shell 1 are integrated into one design, and materials with high thermal conductivity (such as aluminum, copper or aluminum alloy) can be selected to improve the stability and thermal conductivity of the overall structure.

[0078] In some embodiments, refer to Figure 5 and Figure 6 As shown, this application also provides a connector, including: a mounting bracket 27 and a terminal structure as described in the above embodiment, wherein the heat-conducting shell 1 of the terminal structure is mounted on the mounting bracket 27. The connector of this application can be a plug, in which case terminal 2 is a male terminal; the connector can also be a socket, in which case terminal 2 is a female terminal. Furthermore, the number of terminal structures in the connector is not particularly limited; for example, it can be two, three, four, etc., and the specific design can be adjusted according to actual needs.

[0079] Since the connector provided in this application includes the terminal structure of the above embodiments, it has all the technical effects of the terminal structure of the above embodiments, which will not be repeated here.

[0080] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
