[0070] At present, judging from the development of the market situation, the application of batteries is becoming more and more extensive.

With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0071] Batteries are usually connected to connectors for inputting and / or outputting electrical energy. When a large current flows through the connector, it is easy to heat up, causing the temperature to rise. The high temperature of the connector has poor current carrying capacity, which affects the performance and service life of the battery. The connector mounting base is usually made of plastic. In a low temperature environment, the plastic material becomes fragile and brittle, affecting the reliability of the connector and the use of the battery. Therefore, the connector needs to be used within the appropriate temperature to perform better.

[0072] In order to solve this problem, a solution of setting a heat exchange component in the connector has been proposed, but the heat exchange effect of the current solution is not ideal and cannot effectively improve the performance of the connector.

[0073] Based on this, an embodiment of the present application provides a connector, which optimizes the structure of the heat exchange component, increases the heat exchange area of ​​the heat exchange component, and improves the heat exchange effect of the connector, so that the connector can perform better, improve the performance and service life of the battery using the connector, the performance of the electrical device using the connector, and the performance of the charging equipment using the connector.

The number of the side panels 131 may be two, three, four or more than five.

[0107] In some cases, a heat exchange box is provided in the connector 100, and a heat exchange pipe is provided in the wire connected to the connector 100. The heat exchange box is communicated with the heat exchange pipe to provide heat exchange medium to the heat exchange pipe. However, the volume of the heat exchange box of this heat exchange method is large, resulting in a large volume of the connector 100 and poor adaptability of the connector 100. In addition, the heat exchange box does not accommodate much heat exchange medium, the heat exchange area of ​​the heat exchange box is small, and the heat exchange performance of the connector 100 is poor. In addition, the flow path of the heat exchange medium in the heat exchange box is short, further resulting in poor heat exchange performance of the connector 100.

[0108] By adopting the technical solution of this embodiment, the heat exchanger 130 adopts a structure of multiple side panels 131, which has a simple structure and is easy to process and manufacture; in addition, the heat exchanger 130 adopts a plate-like structure formed by multiple side panels 131, so that the heat exchanger 130 can have a larger heat exchange area, which is beneficial to improving the heat exchange effect of the connector 100, and the connector 100 can exert better performance; and, the heat exchanger 130 adopts a plate-like structure, and the space occupied by the heat exchanger 130 is small, which is also beneficial to reducing the volume of the connector 100 and improving the adaptability of the connector 100.

[0109] In another embodiment of the present application, the number of side panel portions 131 is three, and the three side panel portions 131 are divided into a first side panel portion 1311, a second side panel portion 1312 and a third side panel portion 1313. The first side panel portion 1311 and the third side panel portion 1313 are arranged relatively spaced apart, and the second side panel portion 1312 is connected between the side portions of the first side panel portion 1311 and the third side panel portion 1313 located on the same side.

[0110] The first side plate portion 1311 and the third side plate portion 1313 are arranged at intervals relative to each other, the second side plate portion 1312 is connected between one side portion of the first side plate portion 1311 and one side portion of the third side plate portion 1313, and an opening is formed between the other side portion of the first side plate portion 1311 and the other side portion of the third side plate portion 1313, so that the first side plate portion 1311, the second side plate portion 1312 and the third side plate portion 1313 are surrounded to form a U-shaped plate structure, and the space formed by the U-shaped plate structure is the accommodating space 1301, and at least part of the electrical connector 120 is located between the first side plate portion 1311 and the third side plate portion 1313. Of course, in other embodiments, the first side plate portion 1311, the second side plate portion 1312 and the third side plate portion 1313 can also be surrounded to form structures of other shapes, such as a closed triangle shape, etc.

[0111] Through the technical solution of this embodiment, the structure of the heat exchanger 130 is simple and easy to manufacture; the side of the first side plate 1311 facing away from the second side plate 1312 and the side of the third side plate 1313 facing away from the second side plate 1312 form an opening, and the connector 100 that is matched with the connector 100 can be led out from the opening, thereby reducing the overall height dimension of the connector 100 after matching and plugging, so that the connector 100 can be used in some scenes with strict height dimensions. Among them, the overall height direction of the connector 100 after matching and plugging can refer to Figure 7 and Fig. 9 The direction indicated by arrow a.

[0112] In another embodiment of the present application, the plurality of side panel portions 131 are an integrated structure.

[0113] It is understandable that the heat exchanger 130 is a one-piece structure along the circumference of the electrical connector 120, and the plurality of side panels 131 are made by an integrated molding process, wherein the integrated molding process refers to the use of an integrated process such as extrusion, injection molding, and die casting to form a mold. As an example, the heat exchanger 130 may be a long strip-shaped structure, and the heat exchanger 130 is bent along the circumference of the electrical connector 120 to form a U-shaped structure.

[0114] By adopting the technical solution of this embodiment, the multiple side panels 131 are integrated into an integrated structure, which can reduce the manufacturing process. In addition, the structural strength of the heat exchange component 130 is also better, which can also improve the structural strength of the connector 100 and improve the reliability of use.

[0115] In another embodiment of the present application, the electrical connector 120 has an electrical connection portion 121 for electrical plugging, and at least a portion of the electrical connection portion 121 is located in the accommodation space 1301 .

[0116] The electrical connection portion 121 may refer to a portion of the electrical connector 120 that is electrically connected to another connector 100 after the connector 100 and the mating connector 100 are plugged in. As an example, when the electrical connector 120 includes a plug connector 122, the portion of the plug connector 122 that is used to be inserted into the plug hole 1231 is the electrical connection portion 121; when the electrical connector 120 includes a conductive component 123 having a plug hole 1231, the portion of the conductive component 123 that forms the plug hole 1231 is the electrical connection portion 121.

[0117] The electrical connection portion 121 may be partially located in the accommodation space 1301, or may be entirely located in the accommodation space 1301. As an example, in the case where the electrical connection member 120 includes a plug connector 122, in the height direction of the plug connector 122 (see Figures 4 to 6 In the direction indicated by the arrow a in the middle), the upper end of the connector 122 does not protrude outside the heat exchange component 130; of course, in other embodiments, in the height direction of the connector 122, the upper end of the connector 122 may also protrude outside the heat exchange component 130.

[0118] By adopting the technical solution of this embodiment, when in use, the heating of the electrical connection part 121 is more serious, and at least a part of the electrical connection part 121 is located in the accommodating space 1301. The heat exchanger 130 has a good heat exchange effect on the electrical connection part 121, which can effectively reduce the temperature of the electrical connection part 121, thereby effectively improving the performance of the connector 100.

[0119] In one embodiment, the end of the electrical connector 120 facing away from the electrical connection portion 121 may pass through the mounting seat 111 and protrude out of the mounting seat 111 to facilitate electrical connection of the electrical connector 120 .

[0120] In another embodiment of the present application, the mounting seat 111 is provided with an insulating portion 112 , and the insulating portion 112 is coated on the heat exchange element 130 .

[0121] The insulating portion 112 may refer to the insulating portion 112 covering the heat exchanger 130, and the insulating portion 112 is made of insulating material, such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, nylon, polyester, etc. The material of the insulating portion 112 may be the same as or different from the material of the mounting seat 111. The mounting seat 111 and the insulating portion 112 form the housing 110 of the connector 100. In the case where the electrical connector 120 includes a plug connector 122, the electrical connection portion 121 of the plug connector 122 protrudes out of the mounting seat 111, and the insulating portion 112 is disposed outside the plug connector 122, and the insulating portion 112 can guide the conductive component 123 having the plug hole 1231 to be plugged into the plug connector 122; or, in the case where the electrical connector 120 includes a conductive component 123 having the plug hole 1231, the insulating portion 112 is disposed outside the conductive component 123; and the insulating portion 112 is coated on the heat exchange component 130, that is, the heat exchange component 130 is located in the housing 110 of the connector 100, so that the outer dimensions of the connector 100 may not change or change slightly, thereby making the connector 100 have good adaptability. As an example, the insulating portion 112 is coated on the first side plate portion 1311, the second side plate portion 1312 and the third side plate portion 1313, and the insulating portion 112 also has a U-shaped structure.

[0122] By adopting the technical solution of this embodiment, the insulating part 112 can insulate and separate the heat exchange component 130 and the electrical connector 120, thereby reducing the reliability of the connector 100. In addition, the insulating part 112 can also protect the heat exchange component 130. The contact area between the insulating part 112 and the heat exchange component 130 is large, and the heat exchange area between the insulating part 112 and the heat exchange component 130 is large, which is also beneficial to improving the heat exchange effect of the connector 100.

[0125] By adopting the technical solution of this embodiment, the insulating part 112 and the heat exchanger 130 are manufactured by an integrated injection molding process, which is simple in manufacturing process and helps to reduce manufacturing costs. In addition, the connection reliability between the insulating part 112 and the heat exchanger 130 is good, which helps to improve the structural reliability of the connector 100.

[0126] In another embodiment of the present application, the electrical connector 120 includes a plug connector 122 for inserting into the plug hole 1231 , and a gap 140 is formed between the insulating portion 112 and the plug connector 122 .

The heat exchange component 130 can now exchange heat between the conductive component 123 and the connector 122, and the heat exchange effect of the connector 100 is better, which is conducive to the connector 100 to perform better performance.

[0129] In another embodiment of the present application, the electrical connector 120 includes a conductive component 123 having an insertion hole 1231 , and the insulating portion 112 abuts against a side surface of the conductive component 123 facing away from the insertion hole 1231 .

[0130] By adopting the technical solution of this embodiment, the insulating portion 112 is in contact with the side of the conductive component 123 facing away from the plug hole 1231, and the insulating portion 112 can insulate the side of the conductive component 123 facing away from the plug hole 1231. The heat exchange element 130 in the insulating portion 112 can also exchange heat with the conductive component 123, thereby improving the heat exchange effect of the connector 100. In addition, when the plug-in component 122 is inserted into the plug hole 1231, the heat exchange element 130 can exchange heat with the conductive component 123 and the plug-in component 122, thereby achieving a better heat exchange effect for the connector 100, which is conducive to better performance of the connector 100.

[0132] The heat exchange channel 132 may refer to a channel for the heat exchange medium to flow formed inside the heat exchange element 130.

The outflow joint 152 may refer to a component for the heat exchange medium in the heat exchange channel 132 to flow out. The heat exchange medium flows into the heat exchange channel 132 from the inflow joint 151, and the heat exchange medium exchanges heat with the electrical connector 120 during the flow in the heat exchange channel 132; after the heat exchange is completed, the heat exchange medium flows out from the outflow joint 152, thus completing the heat exchange of the connector 100. The heat exchange medium may be air, water, coolant, etc. The inflow joint 151 and the outflow joint 152 may be pipe joints, and the structure of the inflow joint 151 may be the same as or different from the structure of the outflow joint 152.
