[0036] The application provides a connector, which solves the problems of complicated liquid cooling pipeline and large space occupation in the connector. The application also provides an electric device comprising the connector.

[0037] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0038] As shown in the drawings, Figures 1 to 5 The application provides a connector 1, which is electrically connected with a battery pack of an electric device. The connector 1 comprises a terminal 101, a conductor 102 and a medium pipe 103. The terminal 101 is the core hub of power transmission and is used to realize the interaction of signals and data. The terminal 101 is electrically connected with the battery pack and transmits the current delivered by a charging plug to the battery pack when the battery pack is charging. One end of the conductor 102 is connected with the terminal 101, and the other end of the conductor 102 can be connected with the charging plug. When the charging plug is used to charge the battery pack, the conductor 102 is used to transmit the current to the terminal 101, and the terminal 101 is used to transmit the current to the battery pack to realize the charging of the battery pack. The conductor 102 is provided with a through hole, and the medium pipe 103 is arranged in the through hole. The medium pipe 103 is a pipeline for the flow of cooling medium. The medium pipe 103 extends to the position of the terminal 101. The medium pipe 103 is used to guide the cooling medium from one end of the terminal 101 to the other end to realize the cooling of the terminal 101 and further realize the cooling of the terminal 101.

[0039] Specifically, when the charging plug (not shown in the drawings) is connected with the conductor 102 of the connector 1 to charge the battery pack, the charging plug is also provided with a cooling channel (not shown in the drawings). The cooling channel in the charging plug is in communication with the medium pipe 103 in the connector 1. In this way, when the battery pack is charged through the charging plug, the cooling medium of the liquid cooling system on the side of the charging plug flows into the medium pipe 103. The medium pipe 103 extends to the position of the terminal 101. In this way, the cooling medium flows in the medium pipe 103 to cool the terminal 101, so as to ensure that the terminal 101 works in the normal temperature range.

[0040] For example, the cooling medium can be water, a saltwater solution, a glycol mixed solution, freon and the like.

[0041] It should be noted that when the cooling medium is a medium capable of conducting electricity, by providing the medium pipe 103, direct contact between the cooling medium and the conductor 102 can be avoided, and the risk of electric leakage can be avoided. Moreover, the insulating sleeve 1011 is arranged on the outer side of the conductor 102 in the circumferential direction, so that conductor electric leakage can also be avoided.

[0042] The connector 1 with the above structure comprises the terminal 101, the conductor 102 and the medium pipe 103. By providing the through hole in the conductor 102 and arranging the medium pipe 103 in the through hole, and by circulating the cooling medium in the medium pipe 103, the cooling medium flows in the medium pipe 103 to achieve the cooling of the terminal 101. Here, by integrating the medium pipe 103 circulating the cooling medium into the conductor 102, the cooling of the terminal 101 by the cooling medium can be achieved through the connection between the conductors 102, and the separate arrangement of the cooling channel outside the connector 1 can be reduced, and the occupied space of the liquid cooling pipe can be reduced. In addition, when a large current is used to charge the battery pack, the temperature of the conductor 102 will also rise. Here, by integrating the medium pipe 103 circulating the cooling medium into the conductor 102, the conductor 102 can also be cooled when the cooling medium flows in the medium pipe 103, and such an arrangement can also play a role in cooling the conductor 102. Moreover, since the medium pipe 103 is arranged in the through hole in the conductor 102, the heat exchange efficiency of the cooling medium to the conductor 102 can be further improved, and the cooling efficiency of the conductor 102 can be further improved.

[0043] In some embodiments, referring to Figure 1 , the end of the medium pipe 103 away from the terminal 101 is the liquid inlet end or the liquid outlet end, that is, the cooling medium can flow through the position of the terminal 101 first and then flow through the position of the conductor 102, or the cooling medium can flow through the position of the conductor 102 first and then flow through the position of the terminal 101. The liquid inlet end and the liquid outlet end are in communication with the liquid cooling system (not shown in the figure) of the electric equipment, and / or the liquid inlet end and the liquid outlet end can be in communication with the liquid cooling system (not shown in the figure) of the charging plug; that is, the medium pipe 103 can be connected with the liquid cooling system of the electric equipment to form a cooling loop, the medium pipe 103 can also be in communication with the liquid cooling system of the charging plug to form a cooling loop, and the medium pipe 103 can be connected with the liquid cooling system of the electric equipment to form a cooling loop and also be connected with the liquid cooling system of the charging plug to form a cooling loop. The arrangement of the medium pipe 103 in communication with the liquid cooling system of the charging plug to form a cooling loop has been described in the above embodiments. When the medium pipe 103 is in communication with the liquid cooling system of the electric equipment, an interface in communication with the medium pipe 103 can be provided at another position of the connector 1, and the interface can be in communication with the liquid cooling system of the electric equipment, so as to realize the communication between the medium pipe 103 and the liquid cooling system of the electric equipment. In this way, the temperature of the terminal 101 can be efficiently reduced, the cooling channel in the connector can be reduced, and the stability of the overall structure of the connector can be improved.

[0044] In some embodiments, referring to Figure 2 , the connector 1 further comprises a cooling pipeline 104 arranged on the circumferential outer side of the terminal 101, the cooling pipeline 104 is in communication with the medium pipeline 103, and the cooling medium flows through the cooling pipeline 104 to cool the terminal 101 again. Specifically, the medium pipeline 103 extends to the position of the terminal 101, and the cooling medium flowing in the medium pipeline 103 to the position of the terminal 101 cools the terminal 101 to achieve the cooling of the terminal 101; then the cooling medium flows from the medium pipeline 103 to the cooling pipeline 104, and the cooling medium flowing in the cooling pipeline 104 exchanges heat with the area on the circumferential outer side of the terminal 101 to achieve the recooling of the terminal 101. In this way, by flowing of the cooling medium in the medium pipeline 103 and the cooling pipeline 104, different areas of the terminal 101 are cooled, thereby improving the cooling effect of the terminal 101, and cooling different areas of the terminal 101 can improve the uniformity of the cooling of the terminal 101, that is, the temperature of each area of the terminal 101 is reduced.

[0045] In some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the connector 1 further comprises a mounting box 105 provided with a mounting groove 1051, the terminal 101 comprises a main body portion located in the mounting groove 1051 and a connecting portion located outside the mounting groove 1051, the mounting box 105 can fix the terminal 101, and the partial medium pipeline 103 and the cooling pipeline 104 are arranged in the mounting box 105, so that the mounting box 105 can avoid arranging the pipeline for cooling the terminal 101 outside and also play a role in protecting the cooling pipeline 104. The cooling pipeline 104 is a through hole provided on the mounting box 105, and the wall surface of the through hole is in contact with the side wall of the terminal 101. In this way, the cooling pipeline 104 can be integrated into the mounting box 105, which reduces the occupied space of the cooling pipeline 104 and improves the heat exchange efficiency of the cooling pipeline 104 and the terminal 101.

[0046] It should be noted that the number of cooling pipelines 104 is not limited here, and one or more cooling pipelines 104 can be arranged. In order to improve the cooling effect of the terminal 101 and improve the uniformity of the cooling of the terminal 101, a plurality of cooling pipelines 104 are arranged at equal intervals in the circumferential direction of the terminal 101.

[0047] It should also be noted that the arrangement mode of the cooling pipeline 104 is not limited here, for example, the cooling pipeline 104 is arranged in parallel with the axial direction of the terminal 101, or the cooling pipeline 104 is arranged spirally on the circumferential outer side of the terminal 101.

[0048] Further, on the basis of the above-mentioned embodiments, an arc-shaped groove is arranged on the outer side of the terminal 101 in the circumferential direction, and the pipe wall of the cooling pipeline 104 is arranged in abutment with the arc-shaped groove. In this way, the contact area between the cooling pipeline 104 and the terminal 101 can be further increased, and the cooling effect of the cooling pipeline 104 on the terminal 101 can be improved.

[0049] In some embodiments, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the terminal 101 is provided with at least two, and the conductor 102 is arranged in one-to-one correspondence with the terminal 101. The connector 1 further comprises a flow guide plate 106 provided with a flow guide channel 1061. The inlet of the flow guide channel 1061 is in communication with the cooling pipeline 104 on the outer side of one of the adjacent terminals 101 in the circumferential direction, and the outlet of the flow guide channel 1061 is in communication with the cooling pipeline 104 on the outer side of the other terminal 101 in the circumferential direction. Specifically, in this embodiment, two terminals 101 and two conductors 102 are provided. When the charging plug is inserted into the connector 1 to charge the battery pack of the electrical equipment, the liquid cooling system of the electrical equipment and / or the liquid cooling system of the charging plug is in communication with the medium pipe 103, and the cooling medium enters the medium pipe 103 in one of the two adjacent conductors 102. Then, the cooling medium flows along the medium pipe 103 to the cooling pipeline 104 on the outer side of the terminal 101 corresponding to the conductor 102. Then, the cooling medium flows into the flow guide plate 106 through the inlet of the flow guide channel 1061. Then, the cooling medium flows into the cooling pipeline 104 on the outer side of the other terminal 101 through the outlet of the flow guide channel 1061. Then, the cooling medium flows into the medium pipe 103 in the other conductor 102. Finally, the cooling medium flows back to the liquid cooling system of the electrical equipment and / or the liquid cooling system of the charging plug along the medium pipe 103. In this way, a cooling cycle for the terminal 101 can be formed inside the connector 1, and the cooling cycle does not flow into the battery pack, which can simplify the flow circuit of the cooling medium, improve the cooling effect of the terminal 101, and avoid leakage of the cooling liquid in the battery pack, thereby improving the safety of the battery pack when the terminal 101 is cooled.

[0050] Further, the flow guide plate 106 is arranged in the slot of the mounting groove 1051 and abuts against the terminal 101. The flow guide plate 106 abuts against the terminal 101 under the action of an external force, which can limit the installation position of the terminal 101 and improve the stability of the terminal 101.

[0051] It should be noted that the number of terminals 101 and conductors 102 is not limited herein, and both can be provided with two or more. It is only required that the medium pipe 103 capable of cooling the terminal 101 is arranged in each conductor 102. When the terminal 101 and the conductor 102 are both provided with multiple, the flow mode of the cooling medium is similar to the above-mentioned mode, which will not be described herein again.

[0052] It should be further noted that the structure of the flow guide plate 106 is not limited herein, for example, the flow guide plate 106 can be a hollow plate, and a plurality of flow guide channels 1061 can be arranged in the flow guide plate 106, and the two ends of the flow guide channels 1061 are respectively connected to the adjacent cooling pipelines 104.

[0053] In some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the connector 1 further comprises a mounting lug 107, a mounting plate 108 and a connecting piece 109. The mounting lug 107 is arranged on the mounting box 105, and a first connecting hole is formed in the mounting lug 107. The mounting plate 108 is connected to the conductor 102, and a second connecting hole is formed in the mounting plate 108. The connecting piece 109 penetrates and locks the first connecting hole and the second connecting hole to connect the mounting plate 108 and the mounting box 105. In this way, by arranging the connecting piece 109, a pre-tightening force can be applied between the mounting plate 108 and the mounting box 105, so that the mounting plate 108 and the mounting box 105 are tightly abutted, and the installation of the connector 1 is completed. Since the flow guide plate 106 is arranged between the mounting plate 108 and the mounting box 105, when the connecting piece 109 applies the pre-tightening force to the mounting plate 108 and the mounting box 105, the flow guide plate 106 can be in communication with the cooling flow channel, and the flow guide plate 106 and the terminal 101 are in abutment, so as to improve the stability of the overall structure of the connector 1.

[0054] Based on the above embodiments, referring to Figure 2 , the connecting piece 109 comprises a connecting rod 1091 and an abutment plate 1092 located on the side of the connecting rod 1091 away from the mounting lug 107. An elastic member 1010 is sleeved on the connecting rod 1091, and the two ends of the elastic member 1010 are respectively in abutment with the abutment plate 1092 and the mounting plate 108. The elastic member 1010 applies a force to the flow guide plate 106 towards the mounting box 105 through the mounting plate 108. Here, since the communication between the medium pipe 103, the cooling pipeline 104 and the flow guide plate 106 and the limiting installation of the terminal 101 are achieved by the locking force applied between the mounting plate 108 and the mounting lug 107 by the connecting piece 109, when the electrical equipment provided with the connector 1 vibrates, the connection between the medium pipe 103, the cooling pipeline 104 and the flow guide plate 106 may leak. Due to the arrangement of the above-mentioned elastic member 1010, an elastic force can be applied between the medium pipe 103, the cooling pipeline 104 and the flow guide plate 106 when the connector 1 vibrates, so as to reduce the probability of leakage. In addition, the arrangement of the elastic member 1010 can elastically deform when the connector 1 is subjected to an external force, so as to avoid damage to the connector 1 due to a rigid force.

[0055] In addition, the connecting piece 109 can also be arranged in other manners, for example, the abutting plate 1092 is arranged on the side of the connecting rod 1091 away from the mounting box 105, the elastic piece 1010 is sleeved on the connecting rod 1091, and the two ends of the elastic piece 1010 are respectively in abutment with the abutting plate 1092 and the mounting lug 107. In this way, the elastic piece 1010 can also exert a force on the flow guide plate 106 towards the mounting box 105 through the mounting plate 108, so that the mounting plate 108, the flow guide plate 106 and the mounting box 105 are in close abutment.

[0056] In some embodiments, referring to Figure 3 and Figure 4 , the mounting box 105 is provided with a flow guide groove 1052 at the bottom of the mounting groove 1051, the flow guide groove 1052 is in communication with the medium pipe 103 and the cooling pipeline 104, and the communication between the medium pipe 103 and the cooling pipeline 104 can be conveniently realized by arranging the flow guide groove 1052. In addition, the flow guide groove 1052 is arranged one-to-one with the mounting groove 1051, and the adjacent flow guide grooves 1052 are not in communication. In this way, it can be ensured that the cooling medium flows to another adjacent terminal 101 after cooling one terminal 101, so as to ensure that the cooling medium flows in a predetermined manner, improve the moving efficiency of the cooling medium, and further improve the cooling effect on the terminal 101.

[0057] In addition, the cooling medium remaining in the medium pipe 103 flows to the cooling pipeline 104 through the flow guide groove 1052, and since the flow guide groove 1052 is arranged on the side of the mounting box 105 away from the terminal 101 relative to the mounting groove 1051, the mounting groove 1051 and the flow guide groove 1052 are only isolated by the groove wall. In this way, the cooling medium also exchanges heat with the terminal 101 during the flow in the flow guide groove 1052, so as to also cool the bottom of the terminal 101. That is, the arrangement of the flow guide groove 1052 can also further improve the cooling effect on the terminal 101.

[0058] In addition, the connection between the medium pipe 103 and the cooling pipeline 104 can also be realized without arranging the flow guide groove 1052, for example, a flow dividing connector is arranged between the medium pipe 103 and the cooling pipeline 104, so as to also divide the cooling medium in the medium pipe 103 into different cooling pipelines 104.

[0059] In some embodiments, referring to Figure 2 , the side of the mounting plate 108 facing the flow guide plate 106 is provided with an annular protrusion 1081 in abutment with the flow guide plate 106, and the conductor 102 passes through the flow guide plate 106. In this way, the stability of the abutment of the mounting plate 108 with the flow guide plate 106 can be improved, the stability of the abutment of the flow guide plate 106 with the terminal 101 can be improved, and the airtightness of the connection between the flow guide plate 106 and the cooling pipeline 104 can be improved.

[0060] Further, the terminal 101 is provided with a groove 1012 on the side facing the conductor 102, and the conductor 102 abuts against the groove bottom of the groove 1012. The provision of the groove 1012 can improve the convenience of mounting the conductor 102 into the terminal 101, and can improve the contact area between the conductor 102 and the terminal 101 to ensure the stability of the connection between the conductor 102 and the terminal 101, and improve the structural strength of the connector 1 as a whole.

[0061] The application also provides an electrical equipment comprising the above connector 1. The connector 1 comprises the terminal 101, the conductor 102 and the medium pipe 103, by providing a through hole in the conductor 102, and arranging the medium pipe 103 in the through hole, and circulating the cooling medium in the medium pipe 103, so that the cooling medium flows in the medium pipe 103 to cool the terminal 101. Here, by integrating the medium pipe 103 circulating the cooling medium into the conductor 102, the cooling of the terminal 101 by the cooling medium can be realized through the connection between the conductors 102, and the separate arrangement of the cooling pipe 104 outside the connector 1 can be reduced, and the occupied space of the liquid cooling pipe can be reduced. In addition, when a large current is used to charge the battery pack, the temperature of the conductor 102 will also rise, and here the medium pipe 103 circulating the cooling medium is integrated into the conductor 102, and the cooling medium circulating in the medium pipe 103 can also cool the conductor 102, so that the conductor 102 can also be cooled by such an arrangement; and since the medium pipe 103 is arranged in the through hole in the conductor 102, the heat exchange efficiency of the cooling medium to the conductor 102 can be further improved, and the cooling efficiency of the conductor 102 can be further improved.
