[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] Please see Figure 1 and Figure 11 This application provides a connector 1001, which includes a board-end connector 100 and a wire-end connector 200. The board-end connector 100 is used to connect to electrical equipment, and the wire-end connector 200 is plugged into the board-end connector 100 and configured to connect to power supply equipment.

[0042] In some embodiments of this application, the electrical equipment includes vehicle batteries, etc., and the power supply equipment includes charging guns, charging piles, power supplies, etc.

[0043] In this embodiment, the terminals of the board-end terminal group 102 of the line-end connector 200 are plugged into the terminals of the line-end terminal group 201 of the board-end connector 100.

[0044] Please see Figures 2 to 9The board end connector 100 includes a liquid-cooled tail cap 101, which includes a cooling assembly 10 and a board end terminal group 102. The cooling assembly 10 includes a cooling channel 1011 and a connecting groove 1012 communicating with the cooling channel 1011. The cooling channel 1011 is used to contain the cooling medium. The board end terminal group 102 is used to connect with the wire end connector 200. The cooling assembly 10 is connected to the board end terminal group 102. The cooling medium stored in the cooling channel 1011 is in direct contact with the board end terminal group 102 through the connecting groove 1012.

[0045] In some embodiments of this application, the cooling medium can be contained in the cooling channel 1011 and can circulate within the cooling channel 1011. In other embodiments, the cooling medium can be contained in the cooling channel 1011 but cannot circulate.

[0046] In this embodiment, the connecting groove 1012 can be regarded as the opening of the cooling channel 1011, which is a necessary channel for the cooling medium to directly contact the plate end terminal group 102.

[0047] This application provides a cooling assembly 10 on a board-end terminal group 102, and includes a cooling channel 1011 for storing cooling medium and a connecting groove 1012 communicating with the cooling channel 1011 within the cooling assembly 10. The opening of the connecting groove 1012 faces the board-end terminal group 102, allowing the cooling medium to directly contact the board-end terminal group 102. This enables rapid conduction and removal of heat generated when the board-end terminal group 102 is powered on, resulting in fast heat dissipation and short cooling time, thereby improving the heat dissipation efficiency and reliability of the connector.

[0048] Please see Figure 3 and Figure 4 In some embodiments of this application, the cooling assembly 10 further includes a first cooling element 11, the board-end terminal group 102 includes a first terminal 21, and the first cooling element 11 is connected to the first terminal 21; the cooling channel 1011 includes a first sub-cooling channel 111, the connecting groove 1012 includes a first sub-connecting groove 112, and the first sub-cooling channel 111 communicates with the first sub-connecting groove 112; and the first sub-cooling channel 111 and the first sub-connecting groove 112 are both located within the first cooling element 11. The first sub-cooling channel 111 and the first sub-connecting groove 112 cooperate to directly cool the first terminal 21. The cooling medium located in the first sub-cooling channel 111 can directly contact the first terminal 21 through the first sub-connecting groove 112, which can instantly conduct the heat generated when the first terminal 21 is energized and quickly remove the heat. The heat dissipation speed is fast and the cooling time is short, thereby improving the heat dissipation efficiency and reliability of the connector.

[0049] Please see Figure 3 and Figure 4In some embodiments of this application, the cooling assembly 10 further includes a second cooling element 12, and the board-end terminal group 102 further includes a second terminal 22. The second cooling element 12 is connected to the second terminal 22. The cooling channel 1011 further includes a second sub-cooling channel 121, and the connecting groove 1012 further includes a second sub-connecting groove 122. The second sub-cooling channel 121 communicates with the second sub-connecting groove 122. The second sub-cooling channel 121 and the second sub-connecting groove 122 are both located within the second cooling element 12. The second sub-cooling channel 121 and the second sub-connecting groove 122 cooperate to directly cool the second terminal 22. The cooling medium located in the second sub-cooling channel 121 can directly contact the second terminal group 22 through the second sub-connecting groove 122, which can instantly conduct heat generated when the second terminal 22 is energized and quickly remove the heat. The heat dissipation speed is fast and the cooling time is short, thereby improving the heat dissipation efficiency and reliability of the connector.

[0050] The first terminal 21 and the second terminal 22 are constantly working during charging. The long working time generates a lot of heat, so it is necessary to cool the first terminal 21 and the second terminal 22 quickly.

[0051] In some embodiments of this application, the board terminal group 102 further includes a third terminal 23 located on one side of the first terminal 21; the third terminal 23 has a self-heating element for heating the electrical equipment (e.g., a battery pack) at extremely low temperatures.

[0052] In some embodiments of this application, the ends of the first terminal 21 and the second terminal 22 near the cooling assembly 10 are connected to an electrical device (e.g., a battery pack). In this embodiment, the ends of the first terminal 21 and the second terminal 22 near the cooling assembly 10 are electrically connected to the copper busbar of the battery pack.

[0053] In this embodiment, the first sub-connecting groove 112 and the second sub-connecting groove 122 are L-shaped, and the first cooling element 11 and the second cooling element 12 are also L-shaped. In other embodiments, the shapes of the first sub-connecting groove 112, the second sub-connecting groove 122, the first cooling element 11 and the second cooling element 12 are not limited to L-shape, and can be designed according to requirements and actual conditions.

[0054] Please see Figure 3In some embodiments of this application, the cooling assembly 10 further includes a connecting pipe 13, which connects the first cooling element 11 and the second cooling element 12. The connecting pipe 13 has a connecting channel 131, which connects the first sub-cooling channel 111 and the second sub-cooling channel 121. This application achieves shared cooling medium by connecting the connecting channel 131 of the first cooling element 11 and the second sub-cooling channel 121 of the second cooling element 12 through the connecting channel 131 of the connecting pipe 13. This reduces the number of input and output pipes, thereby reducing redundant heat dissipation structures and achieving high efficiency and energy saving.

[0055] Please see Figures 3 to 5 In some embodiments of this application, the cooling assembly 10 further includes a first input terminal 113 and a first output terminal 124. The first input terminal 113 is connected to the first cooling element 11 and communicates with the first sub-cooling channel 111, and the first output terminal 124 is connected to the second cooling element 12 and communicates with the second sub-cooling channel 121. The first input terminal 113 serves as the inflow channel for the cooling medium, and the first output terminal 124 serves as the outflow channel for the cooling medium. The cooling medium of this application can enter the first sub-cooling channel through the first input terminal 113 and flow out of the second sub-cooling channel 121 through the first output terminal 124, thereby achieving the replacement of the cooling medium.

[0056] Please see Figures 3 to 5 and Figure 7 In some embodiments of this application, the cooling assembly 10 further includes a second output terminal 114 and a second input terminal 123. The second output terminal 114 is connected to the first cooling component 11 and communicates with the first sub-cooling channel 111 and the connecting channel 131. The second input terminal 123 is connected to the second cooling component 12 and communicates with the second sub-cooling channel 121 and the connecting channel 131. The cooling medium can enter the first sub-cooling channel 111 from the first input terminal 113, then enter the connecting channel 131 through the second output terminal 114, then enter the second sub-cooling channel 121 through the second input terminal 123, and then flow out from the first output terminal 124.

[0057] In this embodiment, the first input terminal 113 and the second input terminal 123 are inlet nozzles, and the first output terminal 124 and the second output terminal 114 are outlet nozzles.

[0058] Please see Figure 3In some embodiments of this application, the cooling assembly 10 further includes a first seal 14 and / or a second seal 15. The first seal 14 is fixed to one end of the first sub-connecting groove 112 near the first terminal 21, and the second seal 15 is fixed to one end of the second sub-connecting groove 122 near the second terminal 22. The first seal 14 is configured to seal the first sub-connecting groove 112 and the first terminal 21, and the second seal 15 is configured to seal the second sub-connecting groove 122 and the second terminal 22. By using the first seal 14 between the first sub-connecting groove 112 and the first terminal 21, and the second seal 15 between the second sub-connecting groove 122 and the second terminal 22, the cooling medium in the first sub-cooling channel 111 and the second sub-cooling channel 121 is prevented from overflowing beyond the first sub-connecting groove 112 and the first terminal 21, and the second sub-connecting groove 122 and the second terminal 22.

[0059] In this embodiment, the first sealing element 14 and the second sealing element 15 are sealing rings, and the shapes of the first sealing element 14 and the second sealing element 15 correspond to the shapes of the first sub-connecting groove 112 and the second sub-connecting groove 122.

[0060] In other embodiments, the first seal 14 and the second seal 15 may not be disposed within the first sub-connecting groove 112 and the second sub-connecting groove 122. For example, they may be disposed at the end of the wall forming the first sub-connecting groove 112 and the second sub-connecting groove 122 near the first terminal 21 and the second terminal 22.

[0061] In some embodiments of this application, the cooling assembly 10 is detachably connected to the board terminal group 102. The cooling assembly 10 and the board terminal group 102 are independently configured, making disassembly simple and maintenance costs low.

[0062] Please see Figure 3 In some embodiments of this application, the board-end connector 100 further includes a fixing member, which is fixedly connected to the cooling assembly 10. The cooling assembly 10 is detachably connected to the board-end terminal group 102 via the fixing member.

The first terminal 21 has a mounting hole 211, and the first sub-fixing member 115 is inserted into the mounting hole 211. In this embodiment, there are two mounting holes 211; in other embodiments, the number of mounting holes 211 is not limited to two.

[0064] In some embodiments of this application, the fastener is threadedly connected to the plate end terminal group 102, which reduces the manufacturing difficulty and facilitates assembly.

[0065] Please see Figure 3 In this embodiment, the other end of the first sub-fixing member 115 is threaded to the first terminal 21 with a nut 71, and the other end of the second sub-fixing member 125 is threaded to the second terminal 22 with another nut 71. One end of the first sub-fixing member 115 and the second sub-fixing member 125 protrudes from the first protective sleeve 30 and is threaded to the nut.

[0066] In this embodiment, the first terminal 21 and the second terminal 22 are respectively embedded in the first protective sleeve 30 (see below) by the first bolt 72.

[0067] Please see Figure 3 In some embodiments of this application, the liquid-cooled tail cap 101 further includes a first protective sleeve 30, and a plate-end terminal group 102 is fixedly connected to the first protective sleeve 30. The first protective sleeve 30 includes a terminal protective sleeve 301, and the plate-end terminal group 102 is fixedly connected to the terminal protective sleeve 301. The terminal protective sleeve 301 covers at least a portion of one end of the plate-end terminal group and is configured to protect one end of the plate-end terminal group 102.

[0068] In this embodiment, the terminal protective sleeve 301 includes a first sub-protective sleeve 31 and a second sub-protective sleeve 32. One end of the first terminal 21 is disposed in the first sub-protective sleeve 31, and one end of the second terminal 22 is disposed in the second sub-protective sleeve 32. The first sub-fixing member 115 is threadedly connected to the first terminal 21 and the first sub-protective sleeve 31 by a nut. The second sub-fixing member 125 is threadedly connected to the second sub-fixing member 125 and the second sub-protective sleeve 32 by a nut.

[0069] In this embodiment, the terminal protective sleeve 301 further includes a third sub-protective sleeve 33, and the third terminal 23 is disposed on the third sub-protective sleeve 33. The third terminal 23 is fixedly connected to the third sub-protective sleeve 33 by bolts 72. The third sub-protective sleeve 33 is used to protect the third terminal 23.

[0070] In some embodiments of this application, the first protective sleeve 30 further includes a fixing plate 302, which is fixedly connected to the terminal protective sleeve 301, and the cooling assembly 10 is located on the fixing plate 302. The plate end connector 100 further includes a second protective sleeve 104, which is fixedly connected to the fixing plate 302 and covers the end of the plate end terminal group 102 away from the cooling assembly 10.

[0071] In this embodiment, the first cooling component 11, the second cooling component 12, and the connecting pipe 13 are all located on the fixed plate 302.

[0072] In this embodiment, the terminal protective sleeve 301 is integrally connected to the fixing plate 302 or separately connected.

[0073] In some embodiments of this application, the cooling component 10 is either a first-type cooling component or a second-type cooling component. The first-type and second-type cooling components are matched with the board-end terminal group 102, and their heat dissipation capabilities differ. Since the cooling component 10 is divided into first-type and second-type cooling components, meaning the board-end connector 100 is matched with two cooling components with different heat dissipation capabilities, the material of the water tank can be changed according to the actual application scenario and heat dissipation requirements of the product, quickly removing heat and improving product adaptability.

[0074] Of course, in other implementations, the types of cooling components 10 are not limited to two.

[0075] In this embodiment, the first cooling element 11 and the second cooling element 12 of the first type of cooling assembly are both made of ceramic, while the first cooling element 11 and the second cooling element 12 of the second type of cooling assembly are both made of plastic. Compared to plastic, ceramic has a high thermal conductivity and excellent pressure resistance and insulation properties, allowing for rapid heat conduction and resulting in good cooling effect and short cooling time. Compared to plastic, ceramic can prevent the spread of open flame during terminal ablation, cut off direct contact between the temperature rise point and flammable plastic parts, maintain the structural integrity of the connector under extreme high-temperature conditions, and avoid structural failure and short circuits due to reduced insulation or melting.

[0076] In other embodiments, the first cooling element 11 and the second cooling element 12 may be made of materials other than ceramics and plastics, preferably materials with high thermal conductivity, pressure resistance and good insulation properties.

[0078] In some embodiments of this application, the temperature sensing component 103 includes a temperature sensor 51 and a switching element 52. The temperature sensor 51 is disposed near the third terminal 23. The switching element 52 is connected to the temperature sensor 51 and is configured to control the connection or disconnection of the third terminal 23 with the electrical device based on the temperature of the third terminal 23 sensed by the temperature sensor 51, so as to continue heating the electrical device or stop heating.

[0079] In some embodiments of this application, if the temperature of the third terminal 23 sensed by the temperature sensor 51 is lower than a preset threshold temperature, the switch element 52 closes, the third terminal 23 is connected to the electrical device, and the third terminal 23 continues to heat the electrical device. If the temperature of the third terminal 23 sensed by the temperature sensor 51 reaches or exceeds the threshold temperature, the switch element 52 opens, the third terminal 23 is disconnected from the electrical device, and the third terminal 23 stops heating the electrical device.

[0080] In this embodiment, the threshold temperature is 70°C. In other embodiments, the threshold temperature is not limited to 70°C and can be other values, as long as they meet the requirements.

[0081] In some embodiments of this application, the temperature sensing component 103 further includes a heat-conducting element 53, through which the third terminal 23 transfers heat to the temperature sensor 51. The heat-conducting element 53 is used to quickly transfer the heat of the third terminal 23 to the temperature sensor 51, so that the temperature sensor 51 can sense the temperature of the third terminal 23 in a timely manner.

[0082] In some embodiments of this application, the switching element 52 is connected to the third terminal 23. Specifically, the switching element 52 is also connected to the third terminal 23 via a thermally conductive element 53 with adhesive properties. In other embodiments, the switching element 52 may also be connected to the third terminal 23 via adhesive or the like.

[0083] In this embodiment, the thermally conductive element 53 can also be a thermally conductive adhesive.

[0084] In this embodiment, the thermally conductive element 53 comprises thermally conductive silicone. In other embodiments, the thermally conductive element 53 may also be made of other materials with thermal conductivity and adhesion properties.

[0085] In some embodiments of this application, the temperature sensing component 103 further includes a connecting line 54. The temperature sensor 51 and the switching element 52 are connected through the connecting line 54. The temperature sensor 51 and the switching element 52 are also connected to other components through the connecting line 54 to control the board end connector 100 to work or not work.

[0086] Please see Figure 2 and Figure 9In some embodiments of this application, the board-end connector 100 further includes a second protective sleeve 104, which covers the end of the board-end terminal group 102 away from the cooling assembly 10. The second protective sleeve 104 protects the board-end terminal group 102.

[0087] In some embodiments of this application, the second protective sleeve 104 and the fixing plate 302 are locked together by the second bolt 73 engaging with the first screw hole 41 on the fixing plate 302 and the second screw hole 42 on the second protective sleeve 104.

[0088] In some embodiments of this application, the temperature sensor 51 and the switching element 52 are respectively fixed to the second protective sleeve 104. The temperature sensor 51 and the switching element 52 are fixed by setting the second protective sleeve 104.

[0089] In this embodiment, the second protective sleeve 104 includes a first terminal receiving hole 55, a second terminal receiving hole 56, and a third terminal receiving hole 57. The third terminal receiving hole 57 is located between the first terminal receiving hole 55 and the second terminal receiving hole 56. The first terminal receiving hole 55, the second terminal receiving hole 56, and the third terminal receiving hole 57 are respectively used to receive the ends of the first terminal 21, the second terminal 22, and the third terminal 23 that are away from the cooling component 10. The second protective sleeve 104 also includes a first fixing position 58, a second fixing position 59, and a connecting wire receiving groove 60. The first fixing position 58 is located between the first terminal receiving hole 55 and the second terminal receiving hole 56. The connecting wire receiving groove 60 is located below or above the first fixing position 58, the second fixing position 59, the first terminal receiving hole 55, the second terminal receiving hole 56, and the third terminal receiving hole 57. The second fixing position 59 is located between the second terminal receiving hole 56 and the third terminal receiving hole 57. The temperature sensor 51 is fixed to the second fixing position 59. The switching element 52 is fixed to the first fixing position 58. The connecting wire 54 is fixed in the connecting wire receiving groove 60.

[0090] When the board-end connector 100 and the wire-end connector 200 are plugged in, the first terminal 21 and the second terminal 22 of the board-end terminal group 102 are electrically connected to the terminals of the wire-end terminal group 201, respectively. After high power is applied, the first terminal 21 and the second terminal 22 will generate a large amount of heat rapidly. At this time, the cooling medium passes through the first sub-connecting groove 112 and the second sub-connecting groove 122 at the bottom of the first cooling element 11 and the second cooling element 12, and comes into direct contact with the first terminal 21 and the second terminal 22. It can quickly remove the heat and achieve the effect of short cooling time and fast heat removal.
