The heat conduction assembly 32 here is a component with good heat conduction performance, which can realize heat transfer, and the heat transfer between the first end 331 and the box assembly 20 is realized through the heat conduction assembly 32, so that the heat dissipation of the connector assembly 30 can be realized by means of the box assembly 20, thereby accelerating the heat dissipation efficiency of the connector assembly 30.

[0074] It should be noted that the connector assembly 30 here can be connected with the first box 21 or the second box 22, in Figure 3 , the connector assembly 30 is connected with the first box 21 located below.

[0076] It should be noted that the first end 331 is usually in a planar structure and is made of metal material, and heat is generated during the working process. Therefore, the first end 331 needs to be cooled to improve the safety of the battery device 100.

[0077] The structure of the heat conduction assembly 32 will be described in detail below.

[0078] In some embodiments of the present application, as shown in Figure 5 and Figure 6 The heat conduction assembly 32 includes a first heat conduction member 321 and a second heat conduction member 322 that are heat-conductively connected, the first heat conduction member 321 is heat-conductively connected with the connecting terminal 33, and the second heat conduction member 322 is heat-conductively connected with the box assembly 20.

[0079] The first heat conduction member 321 and the second heat conduction member 322 of the heat conduction assembly 32 can be the same or different, for example, the first heat conduction member 321 is made of solid material, and the second heat conduction member 322 is made of paste material, or the first heat conduction member 321 is made of paste material, and the second heat conduction member 322 is made of solid material, which can also achieve the heat transfer performance.

[0084] In order to increase the contact area between the first end 331 and the first heat-conducting member 321, thereby increasing the heat transfer efficiency, the first heat-conducting member 321 in the embodiment of the present application can be in a paste structure or a liquid structure, so as to realize the full contact between the first heat-conducting member 321 and the first end 331 and realize the heat conduction effect.

[0085] In addition, the second heat-conducting member 322 can be arranged on the surface of the mounting base 31 facing the box assembly 20, and correspondingly, the second heat-conducting member 322 can be in a paste structure, a liquid structure or a solid structure. In the embodiment, the first heat-conducting member 321 and the second heat-conducting member 322 can be made of the same heat-conducting material or different heat-conducting materials, and in addition, considering the arrangement position of the second heat-conducting member 322, the second heat-conducting member 322 can be made of a paste material or a solid material, so as to reduce the probability of flowing of the second heat-conducting member 322.

[0086] Alternatively, the second heat-conducting member 322 can also be arranged in the interior of the mounting base 31, as long as it can be in heat-conducting connection with the first heat-conducting member 321.

[0087] The embodiment of the present application arranges the tray member 34 connected with the mounting base 31, arranges at least part of the first end 331 in the tray member 34, further arranges the first heat-conducting member 321 in the tray member 34, and arranges the second heat-conducting member 322 on the mounting base 31, so as to realize the heat-conducting connection between the first end 331 and the first heat-conducting member 321 in the tray member 34, realize the heat-conducting connection between the first heat-conducting member 321 and the second heat-conducting member 322 on the mounting base 31, and increase the heat dissipation area of the connector assembly 30 when the second heat-conducting member 322 is in heat-conducting connection with the box assembly 20.

[0088] In addition, by arranging the tray 34, the selection range of the first heat-conducting member 321 can be expanded, and the first heat-conducting member 321 can be selected as a solid material, a liquid material, or a paste material.

[0089] In some embodiments of the present application, as shown in Figure 6 The surface of the mounting seat 31 facing the cabinet assembly 20 is provided with a groove 312, and the second heat-conducting member 322 is embedded in the groove 312.

[0090] The groove 312 can be annularly distributed along the surface of the mounting seat 31, and at least part of the second heat-conducting member 322 can be embedded in the groove 312. In addition, in order to realize the heat-conducting connection between the second heat-conducting member 322 and the cabinet assembly 20, part of the surface of the second heat-conducting member 322 can be in contact with the cabinet assembly 20, so that the cabinet assembly 20 can realize the heat dissipation effect and accelerate the heat dissipation process of the connector assembly 30.

[0091] Continuing to refer to Figure 6 The groove 312 can be a rectangular structure, and the four corners of the rectangular structure are smoothly connected, so that the installation of the second mounting member in the groove 312 is facilitated. Of course, the groove 312 can also be arranged in a racetrack structure or a rectangular structure.

[0092] The embodiments of the present application arrange the groove 312 on the surface of the mounting seat 31 facing the cabinet assembly 20, and embed the second heat-conducting member 322 in the groove 312, so that the second heat-conducting member 322 can be arranged through the groove 312, and the influence of the second heat-conducting member 322 on the assembly process of the mounting seat 31 and the cabinet assembly 20 is reduced.

[0093] In addition, the second heat-conducting member 322 can be selected as a solid material or a paste material, and the second heat-conducting member 322 can be fixed and installed by being filled in the groove 312.

[0094] In some embodiments of the present application, as shown in Figure 6 The first end 331 has a first projection toward the mounting seat 31, the groove 312 has a first annular structure, and the first annular structure is located outside the circumference of the first projection.

[0095] It should be noted that when the connector assembly 30 is in the installed state, the first end 331 has a horizontal placement structure, and the first projection of the first end 331 toward the mounting seat 31 has a rectangular structure, and the rectangular structure is located inside the first annular structure.

[0096] The embodiment of the present application can make the heat generated by the first end 331 all pass through the first heat conduction member 321 to the second heat conduction member 322, improve the heat transfer efficiency, and thus improve the heat dissipation efficiency of the connector assembly 30, by locating the first projection of the first end 331 towards the first ring structure on the inner side of the first ring structure.

[0097] In some embodiments of the present application, as shown in Figure 5 and Figure 6 The mounting hole 311 is arranged on the outer side of the first ring structure.
