Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a connector, a charging gun, and a charging device. Background Technology

[0002] A charging gun is a connection device that transmits electrical energy from a charging station to an electric vehicle. After the charging gun is plugged into the electric vehicle, the charging station can charge the vehicle using the charging gun. With the rapid development of the electric vehicle industry, the battery capacity of electric vehicles is increasing, and increasing charging power to shorten charging time is one way to achieve fast charging. However, increasing charging power increases the heat dissipation of the charging gun, and excessively high temperatures can affect the reliability and other performance characteristics of the charging gun. Therefore, the heat dissipation efficiency of the charging gun limits the improvement of charging power.

[0003] Liquid cooling is one way to improve the heat dissipation efficiency of charging guns. However, in related technologies, the temperature at the end of the power line connecting to the power supply component is often high, limiting the increase in charging power. Summary of the Invention

[0004] This application provides a connector, a charging gun, and a charging device, which can improve the heat dissipation effect at the end of the power line connected to the power supply component, thereby improving the charging power of the charging gun.

[0005] A first aspect of this application provides a connector including a heat-conducting element. The heat-conducting element has a conduit channel. The conduit channel includes a first segment, a second segment, and a third segment. One end of the first segment penetrates the end face of one end of the heat-conducting element, and the other end of the first segment communicates with one end of both the second and third segments. The other end of the second segment penetrates the end face of the other end of the heat-conducting element. The first and second segments are used for a liquid cooling pipe to pass through, the channel wall of the second segment is used to contact the liquid cooling pipe, the first segment is also used for a power line to pass through, and the third segment is used to accommodate the power line, the channel wall of the third segment is used to contact the power line.

[0006] The connector provided in this application embodiment allows the liquid cooling pipe, which passes through a heat-conducting component, to dissipate heat from the portion of the power line located in the third segment. This reduces the temperature at the end of the power line used to connect to the power supply component, thereby improving the charging power of the charging gun.

[0007] In some possible embodiments, the heat-conducting component includes a first cover portion and a second cover portion, which are disposed opposite to each other in a first direction, with the second cover portion covering the surface of the first cover portion. The surface of the first cover portion facing the second cover portion has a first groove and a second groove, one end of the first groove communicating with one end of the second groove, and the other ends of both the first and second grooves being open structures. The surface of the second cover portion facing the first cover portion has a third groove and a fourth groove, one end of the third groove communicating with one end of the fourth groove, and the other ends of both the third and fourth grooves being open structures. The third groove and the first groove are disposed opposite to each other in the first direction, forming a first segment; the fourth groove and the second groove are disposed opposite to each other in the first direction, forming a second segment. The second cover portion also has a third segment for connecting one end of the first segment to the third groove.

[0008] This makes the assembly of power lines and liquid cooling pipes within the pipeline channel easier.

[0009] In some possible implementations, the surface of the heat-conducting element has an opening that communicates with the third segment.

[0010] This makes it easier for the power line to contact the channel wall of the third section on the outside of the heat-conducting component.

[0011] For example, the power line can be connected to the channel wall of the third section by welding on the outside of the heat-conducting component.

[0012] In some possible implementations, the connector further includes a crimping member that passes through the opening and is used to press and secure the power line to the heat-conducting element.

[0013] This makes it easier for the power line to contact the channel wall of the third section, facilitating the removal of heat from the power line located in the third section by the liquid cooling pipe through the heat-conducting component. Furthermore, it makes the installation and removal of the power cable and connector easier.

[0014] In some possible implementations, the crimping member is a conductive element, and the crimping member is also used for electrical connection with power lines and for electrical connection with power supply components.

[0015] In this way, the crimp connector can simultaneously clamp and secure the power lines while simultaneously establishing an electrical connection between the power lines and the power supply components. The crimp connector can be made of a material with high current-carrying capacity, facilitating high-power current transmission between the power lines and the power supply components. Furthermore, it reduces the requirements for the materials used in the heat-conducting components. Additionally, the connector's structure is relatively simple.

[0016] In some possible embodiments, the opening is located on one side of the surface of the heat-conducting element in a first direction. The heat-conducting element includes an outlet end located at one end of the heat-conducting element in a second direction, and the end of the second segment away from the first segment penetrates through the end face of the outlet end. The crimping member includes a base plate portion, a crimping portion, and a boss portion. The base plate portion is located on one side of the heat-conducting element in the first direction, and both the crimping portion and the boss portion are disposed on the surface of the base plate portion facing the heat-conducting element. The base plate portion includes a first sub-portion and a second sub-portion, the first sub-portion being opposite the opening in the first direction, and the second sub-portion protruding from the outlet end in the second direction. The crimping portion is disposed in the first sub-portion, passes through the opening, and is used to crimp and fix the power line to the heat-conducting element. The boss portion is disposed in the second sub-portion, and the surface of the boss portion away from the base plate portion has a first hole, both ends of the first hole extending in the first direction, the first hole penetrating the crimping member, the first hole being used to pass through a first fastener, and the boss portion being used to position the liquid cooling tube between the crimping end of the first fastener and the base plate portion. The second direction is perpendicular to the first direction, and the end of the boss portion away from the substrate portion is used to abut against the crimping end of the first fastener.

[0017] In this way, the boss portion can increase the distance between the crimping end of the first fastener and the substrate portion, making it less likely that the liquid cooling pipe extending from the second section will be damaged by contact with the tools such as electric screwdrivers or the first fastener when the first fastener is being removed or installed. In addition, the liquid cooling pipe extending from the second section can contact the boss portion to carry away heat from the heat-conducting component through the boss portion, which helps to improve the heat dissipation effect on the heat-conducting component and power lines.

[0018] In some possible implementations, the surface of the crimping member on the side for crimping the power line has an anti-slip structure for contacting the power line.

[0019] This makes the crimping power line of the crimping component more stable.

[0020] In some possible implementations, the opening is located on the surface of the second cover portion of the heat-conducting element opposite to the first cover portion. The crimp member has a second hole extending at both ends in a first direction, penetrating the crimp member. The second cover portion has a third hole opposite to the second hole in the first direction, penetrating the second cover portion. The first cover portion has a fourth hole opposite to the third hole in the first direction. The connector also includes a second fastener passing through the second, third, and fourth holes, used to press and secure the crimp member, power line, second cover portion, and first cover portion.

[0021] In this way, the first cover, the second cover, and the crimping member can be connected by the second fastener, which makes the connector structure more compact and the assembly of the power line and liquid cooling pipe inside the connector more convenient.

[0022] In some possible implementations, the heat conductor has multiple pipeline channels, and the crimping member is used to press and fix the power lines in the multiple third segments onto the heat conductor.

[0023] In this way, multiple power lines can be connected in parallel through multiple pipeline channels, which helps to increase the power supply of the charging gun. Furthermore, the liquid cooling pipes running through the heat-conducting component can dissipate heat from all the power lines crimped by the crimping component, ensuring that the temperature of all the power lines crimped by the crimping component is low. Moreover, when the crimping component is conductive, all the parallel power lines can be electrically connected to the power supply component through the crimping component, making the electrical connection between the parallel power lines and the power supply component relatively convenient.

[0024] In some possible implementations, the surface of the heat-conducting component has multiple openings that correspond one-to-one with the third segment of the pipeline channel. The openings are connected to the corresponding third segments, and the multiple openings are located on the same side of the surface of the heat-conducting component. The crimping component passes through the multiple openings.

[0025] This allows for the creation of holes or other structures between adjacent openings, resulting in higher space utilization on the surface of the heat-conducting component.

[0026] In some possible implementations, the second cover portion further has a fifth hole, the two ends of which extend along a first direction and penetrate through the second cover portion. The first cover portion also has a sixth hole, which is opposite to the fifth hole in the first direction. The connector further includes a third fastener, which passes through the fifth and sixth holes and is used to press and secure the first and second cover portions together.

[0027] Thus, before the crimping component crimps the power line located in the third segment, the heat-conducting component and the power cable can be pre-fixed, making it difficult for the power cable and the heat-conducting component to move freely, which facilitates the crimping component to crimp the power line located in the third segment.

[0028] In some possible implementations, a positioning post is provided on one of the surfaces of the first cover portion facing the second cover portion and the second cover portion facing the first cover portion, and a positioning hole is provided on the other of the surfaces of the first cover portion facing the second cover portion and the second cover portion facing the first cover portion. The positioning post and the positioning hole are arranged opposite to each other in a first direction, and the positioning post is inserted into the positioning hole.

[0029] This makes it easier to align the first and second cover joints and facilitates their connection and fixation. Furthermore, it helps to reduce assembly errors between the first and second cover joints.

[0030] A second aspect of this application provides a charging gun, which includes a charging head, a cable, and a connector as described in any of the above embodiments. The two ends of the cable are connected to the charging head and the connector, respectively. The cable includes a power line and a liquid cooling tube. The liquid cooling tube passes through a first segment and a second segment of the connector, contacting the channel wall of the second segment. The power line passes through the first segment of the connector, and a third segment of the connector accommodates the power line, which contacts the channel wall of the third segment.

[0031] A third aspect of this application provides a charging device, which includes a charging pile and a charging gun as described in any of the above embodiments. The charging pile includes a power supply component and a liquid supply component. The power supply component is electrically connected to the power line of the charging gun, and the liquid supply component is connected to the liquid cooling pipe of the charging gun.

[0054] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0055] Figure 1 This is a schematic diagram of a charging device provided in an embodiment of this application.

[0056] like Figure 1 As shown in the illustration, this application provides a charging device for charging electric vehicles. The charging device includes a charging pile 2 and a charging gun 1, with the charging pile 2 connected to the charging gun 1. The charging pile 2 provides electrical energy, and the charging gun 1 is a connection device that transmits electrical energy from the charging pile 2 to the electric vehicle. After the charging gun 1 is plugged into the electric vehicle, the charging pile 2 can charge the electric vehicle through the charging gun 1.

[0057] The charging gun 1 includes a gun head 10 and a cable 20, with both ends of the cable 20 connected to the gun head 10 and the charging station 2, respectively. The charging station 2 includes a power supply component 40, which can be connected to the mains power supply via a charging host. The charging host can convert the current supplied by the mains power supply into the current required for charging the electric vehicle. The cable 20 includes a power cable 500 (as follows). Figure 5 As shown in the diagram, the power cable 500 includes a power wire 510 (as shown below). Figure 4 As shown in the figure, and an insulating layer (not shown) covering the outside of the power line 510, the power line 510 includes a gun head connection end and a power supply connection end, both of which extend out of the insulating layer, the gun head connection end is electrically connected to the gun head 10, and the power supply connection end is electrically connected to the power supply assembly 40.

[0058] The nozzle 10 includes a power terminal (not shown), and the nozzle connection end is electrically connected to the power terminal. For example, the nozzle connection end can be connected to the power terminal by welding, fastener connection, or other methods.

[0059] For example, the power supply component 40 has a connecting copper busbar (not shown), and the power supply connection terminal is electrically connected to the connecting copper busbar.

[0060] For example, the gun head 10 includes two power terminals, the cable 20 includes at least two power cables 500, and the power supply assembly 40 includes two connecting copper busbars. One power terminal is electrically connected to one connecting copper busbar via a power line 510 of at least one power cable 500, and the other power terminal is electrically connected to another connecting copper busbar via a power line 510 of at least one power cable 500. The power cables 500 electrically connected to different connecting copper busbars are different power cables 500.

[0061] For example, cable 20 may also include an outer sheath, a signal cable, a grounding cable, and a filler. The outer sheath covers the outside of the power cable 500, the signal cable, the grounding cable, and the filler. The filler is used to fill the gaps in the outer sheath. Both ends of the power cable 500, the signal cable, and the grounding cable extend out of the outer sheath.

[0062] To improve the heat dissipation efficiency of the charging gun 1, the cable 20 also includes a liquid cooling pipe 520, which is sleeved inside the outer sheath. The charging pile 2 may also include a liquid supply assembly 50, which is connected to the liquid cooling pipe 520 and is used to supply coolant to the liquid cooling pipe 520. The liquid cooling pipe 520 can contact the power line 510, and can provide liquid cooling for the power line 510.

[0063] In some examples, the power cable 500 may include a liquid cooling tube 520 (as follows). Figure 4 As shown in the diagram, the power line 510 is wrapped around the surface of the liquid cooling pipe 520, and the insulating layer is wrapped around the surface of the power line 510.

[0064] In some examples, the nozzle 10 may also include a liquid cooling assembly (not shown) connected to a liquid cooling pipe 520. The liquid cooling assembly may contact the power terminals and dissipate heat from them.

[0065] For example, cable 20 includes at least two liquid-cooled pipes 520, at least one of which is an inlet liquid-cooled pipe and at least one of which is a return liquid-cooled pipe. For instance, one power cable 500 of cable 20 includes an inlet liquid-cooled pipe 520, and another power cable 500 of cable 20 includes a return liquid-cooled pipe 520. One end of the inlet liquid-cooled pipe is connected to the outlet end of the liquid supply assembly 50, and the other end is connected to the inlet end of the liquid cooling assembly. One end of the return liquid-cooled pipe is connected to the outlet end of the liquid cooling assembly, and the other end is connected to the return end of the liquid supply assembly 50.

[0066] like Figure 1 As shown, based on this, in this embodiment of the application, the charging gun 1 further includes a connector 30. Both ends of the cable 20 are connected to the gun head 10 and the connector 30, respectively. The connector 30 is used to connect the cable 20 to the charging pile 2; that is, the end of the cable 20 furthest from the gun head 10 is connected to the charging pile 2 via the connector 30. The power line 510 of the cable 30 is connected to the power supply component 40 via the connector 30, and the liquid cooling pipe 520 of the cable 30 passes through the connector 30 and is connected to the liquid supply component 50.

[0067] Figure 2This is a schematic diagram of one end of a connector in a second direction, provided in an embodiment of this application. Wherein, x represents a first direction, z represents a third direction, and both the first and third directions are perpendicular to the second direction, with the first direction being perpendicular to the third direction.

[0068] like Figure 2 As shown in the embodiment of this application, the connector 30 includes a heat-conducting element 100, and the heat-conducting element 100 has a pipeline channel 300.

[0069] For example, the heat-conducting element 100 can be an insulating element or a conductive element. The material used to make the heat-conducting element 100 can include one or more of the following: metal, ceramic, thermally conductive polymer, etc. For example, the heat-conducting element 100 can be made of aluminum or aluminum alloy.

[0070] Figure 3 for Figure 2 The diagram shows a cross-sectional view of the connector at section AA. The y-direction is the second direction.

[0071] like Figure 3 As shown, the pipeline channel 300 includes a first section 310, a second section 320 and a third section 330. One end of the first section 310 passes through the end face of one end of the heat-conducting component 100. The other end of the first section 310 is connected to one end of the second section 320 and one end of the third section 330. The other end of the second section 320 passes through the end face of the other end of the heat-conducting component 100.

[0072] For example, the end of the third segment 330 that is away from the first segment 310 can be a closed structure.

[0073] Figure 4 for Figure 2 The diagram shows the cross-section of the connector provided with a power cable at section AA.

[0074] like Figure 4 As shown, and see Figure 3 The first segment 310 and the second segment 320 are used for the liquid cooling pipe 520 to pass through. That is, the liquid cooling pipe 520 passes through the first segment 310 and the second segment 320, and the channel wall of the second segment 320 is in contact with the liquid cooling pipe 520. The first segment 310 is also used for the power line 510 to pass through. That is, the power line 510 passes through the first segment 310. The third segment 330 is used to accommodate the power line 510. That is, the third segment 330 contains the power line 510. The channel wall of the third segment 310 is used to contact the power line 510. The power line 510 accommodated in the third segment 330 is electrically connected to the power supply component 40, and the liquid cooling pipe 520 extending from the end of the second segment 320 away from the first segment 310 is connected to the liquid supply component 50.

[0075] In this way, compared to the scheme of branching the power line 510 and the liquid cooling pipe 520 and welding them to the connecting copper busbar, the liquid cooling pipe 520, which is installed in the heat-conducting component 100, can dissipate heat on the part of the power line 510 located in the third segment 330 through the heat-conducting component 100, thereby reducing the temperature of the end of the power line 510 used to connect to the power supply component 40, and thus helping to improve the charging power of the charging gun 1.

[0076] For example, the power supply connection of the power line 510 is housed within the third segment 330.

[0077] For example, the liquid cooling pipe 520 passing through the first section 310 and the second section 320 can be either an inlet liquid cooling pipe or a return liquid cooling pipe.

[0078] For example, the liquid cooling pipe 520 and power line 510 inserted in the first segment 310 are pressed together by the channel wall of the first segment 310.

[0079] For example, the liquid cooling pipe 520 inserted inside the second section 320 is pressed against the channel wall of the second section 320.

[0080] In some examples, portions of the insulating layer may be located within the first segment 310.

[0081] In other examples, the insulation layer is located outside the first segment 310, that is, the portions of the liquid cooling pipe 520 and the power line 510 that extend out of the insulation layer are inserted inside the first segment 310.

[0082] like Figure 3 As shown, in some possible embodiments, the surface of the heat-conducting element 100 has an opening 122 that communicates with the third segment 330.

[0083] This facilitates the contact between the power line 510 and the channel wall of the third segment 330 on the outside of the heat-conducting component 100.

[0084] like Figure 3 , Figure 4 As shown, in some possible embodiments, connector 30 further includes crimp member 200, which passes through opening 122 and crimps power line 510 to heat-conducting member 100.

[0085] This makes it easier for the power line 510 to come into contact with the channel wall of the third segment 330, facilitating the removal of heat from the power line 510 located within the third segment 330 by the liquid cooling pipe 520 through the heat conductor 300. Furthermore, it makes it easier to assemble and disassemble the power cable 500 and the connector 30.

[0086] The opening 122 is located on one side of the surface of the heat-conducting element 100 in the first direction.

[0087] In some examples, the crimping member 200 can be an insulating component, and the thermally conductive member 300 can be a conductive component. The thermally conductive member 300 is electrically connected to the power supply component 40, so that the power line 510 can be electrically connected to the power supply component 40 through the thermally conductive member 300. For example, the thermally conductive member 300 can be connected to the connecting copper busbar by means of welding, fastener connection, etc.

[0088] In other examples, the crimp 200 can be a conductive element, electrically connected to the power line 510, and electrically connected to the power supply component 40, so that the power line 510 can be electrically connected to the power supply component 40 through the crimp 200. For example, the crimp 200 can be connected to the connecting copper busbar by means of welding, fastener connection, etc.

[0089] In this way, the crimping member 200 can simultaneously clamp and fix the power line 510 while achieving an electrical connection between the power line 510 and the power supply component 40. The crimping member 200 can be made of a material with high current carrying capacity, which is beneficial for high-power current transmission between the power line 510 and the power supply component 40. In addition, it can also reduce the requirements for the material selection of the heat-conducting component 300. Furthermore, the structure of the connector 30 is also relatively simple.

[0090] For example, the crimping member 200 can be a metal part. For instance, the crimping member 200 can be made of copper.

[0091] In some other possible implementations, the power line 510 can be welded to the channel wall of the third segment 330. When the heat-conducting element 300 is a conductive element, the power line 510 located in the third segment 330 can be electrically connected to the heat-conducting element 300 by welding.

[0092] like Figure 3 As shown, the heat-conducting component 100 includes an outlet end 150 and an inlet end 160. The end of the first segment 310 away from the second segment 320 passes through the end face of the inlet end 160, and the end of the second segment 320 away from the first segment 310 passes through the end face of the outlet end 150. The outlet end 150 is located at one end of the heat-conducting component 100 in the second direction, and the inlet end 160 can be located at the other end of the heat-conducting component 100 in the second direction or at one end of the heat-conducting component 100 in the third direction, making it easier to arrange the liquid cooling pipe 520 in the pipeline channel 300.

[0093] For example, both ends of the first segment 310 and both ends of the second segment 320 extend along the second direction. The second segment 320 is located on one side of the first segment 310 in the second direction. The outlet end 150 and the inlet end 160 are located at both ends of the heat-conducting element 100 in the second direction, making it easier to insert the liquid cooling pipe 520 in the first segment 310 and the second segment 320.

[0094] In some examples, the third segment 330 is located on one side of the second segment 320 in the first direction, and the opening 122 is located on the side of the third segment 330 opposite to the second segment 320 in the first direction.

[0095] Figure 5 This is a schematic diagram from one perspective of a connector with a power cable threaded through it, provided as an embodiment of this application.

[0096] like Figure 5 As shown, in some examples, the charging device further includes a first fastener 430 that passes through the crimp member 200. The crimp member 200 is fixedly connected to the power supply component 40 via the first fastener 430, thereby electrically connecting the crimp member 200 to the power supply component 40. For example, the crimp member 200 is fixedly connected to a connecting copper busbar via the first fastener 430, thereby electrically connecting the crimp member 200 to the connecting copper busbar.

[0097] In some examples, connector 30 may also include a second fastener 410 that passes through crimp member 200 and heat conductor 100, and crimp member 200 and heat conductor 100 are detachably connected by the second fastener 410, which presses and secures crimp member 200, power line 510 and heat conductor 100.

[0098] In some possible implementations, the heat-conducting component 100 has multiple pipeline channels 300, and the crimping member 200 presses and fixes the power lines 510 in the multiple third segments 330 onto the heat-conducting component 100. That is, the crimping member 200 presses and fixes the power lines 510 in the third segments 330 of the multiple pipeline channels 300 onto the heat-conducting component 100.

[0099] In this way, multiple power lines 510 can be connected in parallel through multiple pipeline channels 300, which helps to increase the power supply of the charging gun 1. In addition, the liquid cooling pipe 520 passing through the heat-conducting component 100 can dissipate heat from all the power lines 510 crimped by the crimping component 200 through the heat-conducting component 100, so that the temperature of all the power lines 510 crimped by the crimping component 200 is low. Furthermore, when the crimping component 200 is a conductive component, all the parallel power lines 510 can be electrically connected to the power supply component 40 through the crimping component 200, which is convenient.

[0100] For example, each pipeline channel 300 corresponds to one power cable 500. That is, the first segment 310 and the second segment 320 of each pipeline channel 300 are for the liquid cooling pipe 520 of the corresponding power cable 500 to pass through, the first segment 310 of each pipeline channel 300 is also for the power line 510 of the corresponding power cable 500 to pass through, and the third segment 330 of each pipeline channel 300 accommodates the power line 510 of the power cable 500.

[0101] For example, power line 510 electrically connected to the same crimp 200 is electrically connected to the same power terminal, and power line 510 electrically connected to the same crimp 200 is electrically connected to the same connecting copper busbar.

[0102] In some examples, the surface of the heat-conducting component 100 has a plurality of openings 122 that correspond one-to-one with the third segment 330 of the pipeline channel 300. The openings 122 are connected to the corresponding third segment 330. The plurality of openings 122 are located on the same side of the surface of the heat-conducting component 100, and the crimping component 200 passes through the plurality of openings 122.

[0103] This makes it easier to create holes or other structures between two adjacent openings 122, which allows for higher space utilization on the surface of the heat-conducting component 100.

[0104] For example, at least two power cables 500 include a first power cable 500a and a second power cable 500b, and multiple pipeline channels 300 include a first pipeline channel 300a and a second pipeline channel 300b. The first power cable 500a includes a first liquid cooling pipe 520a and a first power line. The first pipeline channel 300a and the second pipeline channel 300b are arranged side by side along a third direction. The first liquid cooling pipe 520a passes through a first section 310 and a second section 320 of the first pipeline channel 300a. The first power line passes through the first section 310 of the first pipeline channel 300a, and a portion of the first power line is located in the third section 330 of the first pipeline channel 300a. The second power cable 500b includes a second liquid cooling pipe 520b and a second power line. The second liquid cooling pipe 520b passes through the first section 310 and the second section 320 of the second pipeline channel 300b. The second power line passes through the first section 310 of the second pipeline channel 300b, and a portion of the second power line is located in the third section 330 of the second pipeline channel 300b. The opening 122 communicating with the third section 330 of the first pipeline channel 300a and the opening 122 communicating with the third section 330 of the second pipeline channel 300b are located on the same side of the surface of the heat-conducting member 100. The crimping member 200 passes through... Within the opening 122 connecting the third segment 330 of the first pipeline channel 300a and the opening 122 connecting the third segment 330 of the second pipeline channel 300b, the crimping member 200 presses and fixes both the first power line and the second power line onto the heat-conducting member 100 and electrically connects them. The first power line and the second power line are electrically connected to the same power terminal. One of the first liquid cooling pipe 520a and the second liquid cooling pipe 520b is the liquid inlet liquid cooling pipe, and the other of the first liquid cooling pipe 520a and the second liquid cooling pipe 520b is the liquid outlet liquid cooling pipe 520.

[0105] For example, at least two power cables 500 may further include a third power cable and a fourth power cable. The charging gun 1 may include two connectors 30, which are a first connector and a second connector, respectively. The first connector is connected to the first power cable 500a and the second power cable 500b according to the assembly method described above. The second connector is connected to the third power cable and the fourth power cable with reference to the assembly method of the first power cable 500a and the second power cable 500b with the connector 30 described above. The power terminals electrically connected to the power lines 510 of the third power cable and the power lines 510 of the fourth power cable are different from the power terminals electrically connected to the power lines 510 of the first power cable 500a and the second power cable 500b. The connecting copper busbars electrically connected to the power lines 510 of the third power cable and the fourth power cable are different from the connecting copper busbars electrically connected to the power lines 510 of the first power cable 500a and the second power cable 500b.

[0106] In other examples, the opening 122 is connected to a plurality of third segments 330, and the crimping member 200 passing through the opening 122 crimps and fixes the power line 510 in the third segment 330 connected to the opening 122 onto the heat-conducting member 100.

[0107] Figure 6 This is a schematic diagram from one perspective of a crimping component provided in an embodiment of this application. Figure 7 for Figure 6 Another perspective diagram of the crimping component provided in the diagram. Figure 8 for Figure 5 The diagram provided shows another perspective of the connector with a power cable threaded through it.

[0108] like Figures 6-8 As shown, in some possible embodiments, the crimping member 200 includes a substrate portion 210, a crimping portion 220, and a boss portion 230. The substrate portion 210 is located on one side of the heat-conducting member 100 in the first direction, and the crimping portion 220 and the boss portion 230 are both provided on the surface of the substrate portion 210 facing the heat-conducting member 100.

[0109] The substrate portion 210 includes a first sub-portion 211 and a second sub-portion 212. The first sub-portion 211 is opposite to the opening 122 in a first direction, and the second sub-portion 212 protrudes from the outlet end 150 in a second direction. A crimping portion 220 is provided in the first sub-portion 211 and passes through the opening 122. The crimping portion 220 is used to crimp and fix the power line 510 onto the heat-conducting member 100. A boss portion 230 is provided in the second sub-portion 212. The surface of the boss portion 230 away from the substrate portion 210 has a first hole 250. The two ends of the first hole 250 extend in a first direction and pass through the crimping member 200. The first hole 250 is used to pass through the first fastener 430.

[0110] The first fastener 430 includes a rod portion 432 and a crimp end 431. The crimp end 431 is disposed at one end of the rod portion 432. The rod portion 432 is connected to the power supply assembly 40, for example, the rod portion 432 can be connected to a connecting copper busbar. The end of the boss portion 230 away from the substrate portion 210 abuts against the crimp end 431 to fix the crimp member 200 to the power supply assembly 40. The boss portion 230 is used to position the liquid cooling pipe 520 between the crimp end 431 of the first fastener 430 and the substrate portion 210.

[0111] In this way, the boss portion 230 can increase the distance between the crimping end 431 of the first fastener 430 and the substrate portion 210, making the liquid cooling pipe 520 extending from the second section 320 less likely to be damaged by contact with the tools such as electric screwdrivers or the first fastener 430 when the first fastener 430 is being removed or installed. In addition, the liquid cooling pipe 520 extending from the second section 320 can contact the boss portion 230 to remove heat from the heat conductor 100 through the boss portion 230, which helps to improve the heat dissipation effect on the heat conductor 100 and the power line 510.

[0112] In some examples, the boss 230 can be a cylindrical structure.

[0113] In other examples, the boss 230 may also be a polyprism structure, a frustum structure, or a truncated pyramid structure.

[0114] In some examples where the second segment 320 extends along the second direction at both ends and the boss portion 230 is a cylindrical structure, the distance between the axis of the second segment 320 and the axis of the boss portion 230 is less than the sum of the radius of the liquid cooling pipe 520 and the radius of the boss portion 230. The radius of the liquid cooling pipe 520 refers to half of the outer diameter of the liquid cooling pipe 520, and the radius of the boss portion 230 refers to half of the outer diameter of the boss portion 230. This is so that the liquid cooling pipe 520 extending from the second segment 320 can contact the side of the boss portion 230.

[0115] When the crimping member 200 passes through the plurality of openings 122, the substrate portion 210 is provided with a plurality of crimping portions 220 corresponding one-to-one with the plurality of openings 122, and each crimping portion 220 passes through the corresponding opening 122.

[0116] When the first liquid cooling pipe 520a and the second liquid cooling pipe 520b pass through the second section 320 of the first pipeline channel 300a and the second section 320 of the second pipeline channel 300b respectively, the boss portion 230 can be located between the first liquid cooling pipe 520a and the second liquid cooling pipe 520b.

[0117] For example, the first fastener 430 can be a bolt, and the clamping end of the first fastener 430 can be a screw head.

[0118] In some examples, the distance between the end of the boss portion 230 away from the substrate portion 210 and the substrate portion 210 in the first direction is greater than the distance between the end of the second segment 320 away from the first segment 310 and the substrate portion 210 in the first direction. In this way, the liquid cooling pipe 520 can be located between the crimping end 431 of the first fastener 430 and the substrate portion 210.

[0119] In some examples, a gasket is provided between the crimping end 431 of the first fastener 430 and the boss portion 230. The sum of the distance between the end of the boss portion 230 away from the substrate portion 210 and the substrate portion 210 in the first direction and the thickness of the gasket is greater than the distance between the side of the second segment 320 away from the first segment 310 and the substrate portion 210 in the first direction. In this way, the liquid cooling pipe 520 can be located between the crimping end 431 of the first fastener 430 and the substrate portion 210.

[0120] like Figure 6 As shown, in some possible embodiments, the surface of the crimping member 200 for crimping the power line 510 has an anti-slip structure 221 for contacting the power line 510.

[0121] This makes the crimping of the power line 510 by the crimping component 200 more stable.

[0122] For example, the crimping portion 220 has an anti-slip structure 221.

[0123] For example, the anti-slip structure 221 may include one or more of the following: anti-slip ridges, anti-slip textures, anti-slip protrusions, etc.

[0124] In some possible implementations, the heat-conducting element 100 is an integral structure.

[0125] Figure 9 This is a schematic diagram of a first cover portion provided in an embodiment of this application. Figure 10 This is a schematic diagram from one perspective of a second cover portion provided in an embodiment of this application. Figure 11 for Figure 10 A schematic diagram of the second cover section from another perspective is provided. Figure 12 for Figure 10 The second cover provided is in Figure 2 A schematic diagram of the cross-section at section AA. Figure 13 This is an exploded view of a connector provided in an embodiment of this application.

[0126] like Figures 9-13 As shown, in some other possible embodiments, the heat-conducting component 100 has a split structure. The heat-conducting component 100 includes a first cover portion 110 and a second cover portion 120, which are disposed opposite to each other in a first direction, and the second cover portion 120 covers the surface of the first cover portion 110.

[0127] The surface of the first cover portion 110 facing the second cover portion 120 has a first groove 311 and a second groove 321. One end of the first groove 311 is connected to one end of the second groove 321, and the other end of the first groove 311 and the other end of the second groove 321 are both open structures.

[0128] The surface of the second cover portion 120 facing the first cover portion 110 has a third groove 312 and a fourth groove 322. One end of the third groove 312 is connected to one end of the fourth groove 322, and the other end of the third groove 312 and the other end of the fourth groove 322 are both open structures.

[0129] The third groove 312 and the first groove 311 are arranged opposite to each other in the first direction, and the third groove 312 and the first groove 311 enclose each other to form the first segment 310. The fourth groove 322 and the second groove 321 are arranged opposite to each other in the first direction, and the fourth groove 322 and the second groove 321 enclose each other to form the second segment 320.

[0130] The second cover portion 120 also has a third section 330, which is used to connect one end of the first section 310 to the third groove 312.

[0131] This makes it easier to assemble the power line 510 and the liquid cooling pipe 520 within the pipeline channel 300.

[0132] In some examples where the heat-conducting element 100 has an opening 122, the second cover portion 120 also has an opening 122, and the crimping member 200 is used to press and fix the power line 510 onto the second cover portion 120.

[0133] In some examples, the first cover portion 110 and the second cover portion 120 can be fixedly connected by non-removable means such as welding or riveting.

[0134] In other examples, the first cover portion 110 and the second cover portion 120 can be fixedly connected by a detachable means such as snap-fit ​​or threaded fastener connection.

[0135] In some possible embodiments, the opening 122 is located on the surface of the second cover portion 120 opposite to the first cover portion 110. The crimping member 200 has a second hole 240, the two ends of which extend along a first direction and penetrate the crimping member 200. The second cover portion 120 has a third hole 121, the two ends of which extend along a first direction and are opposite to the second hole 240 in the first direction, and penetrate the second cover portion 120. The first cover portion 110 has a fourth hole 111, the two ends of which extend along a first direction and are opposite to the third hole 121 in the first direction. A second fastener 410 passes through the second hole 240, the third hole 121, and the fourth hole 111, and the second fastener 410 is used to press and fix the crimping member 200, the power line 510, the second cover portion 120, and the first cover portion 110.

[0136] In this way, the first cover portion 110, the second cover portion 120 and the crimping member 200 can be connected by the second fastener 410, which makes the structure of the connector 30 more compact and the assembly of the power line 510 and the liquid cooling pipe 520 within the connector 30 more convenient.

[0137] In some examples, the second fastener 410 is a bolt, and the fourth hole 111 is a threaded hole, with the second fastener 410 threadedly connected to the hole wall of the fourth hole 111.

[0138] In other examples, the second fastener 410 is a bolt, and the portion of the second fastener 410 extending out of the fourth hole 111 is threadedly connected to a nut located on the side of the first cover portion 110 opposite to the second cover portion 120.

[0139] In some examples where the heat-conducting element 100 has two pipeline channels 300 arranged side by side along a third direction, the second hole 240, the third hole 121 and the fourth hole 111 may all be located between the two pipeline channels 300.

[0140] In some possible embodiments, the second cover portion 120 further has a fifth hole 123, both ends of which extend along a first direction and penetrate through the second cover portion 120. The first cover portion 110 further has a sixth hole 112, both ends of which extend along a first direction and are opposite to the fifth hole 123 in the first direction. The connector 30 also includes a third fastener 420, which passes through the fifth hole 123 and the sixth hole 112, and is used to press and fix the first cover portion 110 and the second cover portion 120 together.

[0141] In this way, before the crimping member 200 crimps the power line 510 located in the third segment 330, the heat-conducting member 100 and the power cable 500 can be pre-fixed, so that the power cable 500 and the heat-conducting member 100 are not easily moved, making it easier for the crimping member 200 to crimp the power line 510 located in the third segment 330.

[0142] For example, when assembling the liquid cooling tube 520 and the power line 510 on the connector 30, the power line 510 and the liquid cooling tube 520 located in the first segment 310 can be pressed by the channel wall of the first segment 310 using the third fastener 420, and the liquid cooling tube 520 located in the second segment 320 can be pressed by the channel wall of the second segment 320. Part of the power line 510 is located in the third segment 330. Then, the crimping member 200 is inserted into the opening 122, and the crimping member 200, the power line 510 in the third segment 330, the second cover portion 120 and the first cover portion 110 are pressed and fixed by the second fastener 410.

[0143] For example, the fifth hole 123 and the third hole 121 can be arranged in a row along the second direction, with the fifth hole 123 located between the inlet end 160 and the third hole 121.

[0144] In some examples, the third fastener 420 is a bolt, and the sixth hole 112 is a threaded hole, with the third fastener 420 threadedly connected to the wall of the sixth hole 112.

[0145] In other examples, the third fastener 420 is a bolt, and the fifth hole 123 is a threaded hole, with the third fastener 420 threadedly connected to the wall of the fifth hole 123.

[0146] In some other examples, the third fastener 420 is a bolt, and the portion of the third fastener 420 that extends out of the sixth hole 112 is threadedly connected to a nut located on the side of the first cover portion 110 opposite to the second cover portion 120.

[0147] In some possible embodiments, a positioning post 130 is provided on one of the surfaces of the first cover portion 110 facing the second cover portion 120 and the second cover portion 120 facing the first cover portion 110, and a positioning hole 140 is provided on the other of the surfaces of the first cover portion 110 facing the second cover portion 120 and the second cover portion 120 facing the first cover portion 110. The positioning post 130 and the positioning hole 140 are arranged opposite to each other in a first direction, and the positioning post 130 is inserted into the positioning hole 140.

[0148] This makes it easier to align the first cover portion 110 and the second cover portion 120, and facilitates the connection and fixation of the first cover portion 110 and the second cover portion 120. In addition, it also helps to reduce the assembly error of the first cover portion 110 and the second cover portion 120.

[0149] For example, the surface of the first cover portion 110 facing the second cover portion 120 has a positioning post 130, and the surface of the second cover portion 120 facing the first cover portion 110 has a positioning hole 140, which can be a through hole.

[0150] For example, the fifth hole 123, the positioning hole 140 and the third hole 121 can be arranged in a row along the second direction, with the positioning hole 140 located between the fifth hole 123 and the third hole 121.

[0151] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

[0152] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
