[0069] The plug-in connector 130 is arranged on the leading bracket 120, and one end of the plug-in connector 130 is exposed outside the frame 110.

[0070] The insertion part 121 and the frame 110, and the leading bracket 120 and the frame 110 are respectively provided with a first sealing element.

[0071] It can be understood that the plug-in connector leading structure 100 provided by the present application can be applied to the battery pack, a plurality of battery cell groups 200 in the battery pack can be installed in the frame 110, the battery cell groups 200 are connected through bus bars 300, one end of the bus bar 300 is connected with an electrical assembly in the battery pack, the other end is connected with the plug-in connector 130, and the part of the plug-in connector 130 exposed outside the frame 110 is connected with an electric drive element in the vehicle.

[0072] Referring to Figure 2 and Figure 3As shown, by setting the through hole 111 on the frame 110, the lead-out support 120 is set on the frame 110 covering the through hole 111, and the insertion part 121 is correspondingly inserted into the through hole 111. The insertion part 121 can play a positioning role to facilitate the installation of the lead-out support 120. Moreover, the insertion part 121 abuts against the inner wall of the through hole 111, forming an effective stress point, reducing the displacement or loosening of the lead-out support 120 caused by external force or vibration during assembly and use, thereby improving the stability of the connection between the lead-out support 120 and the frame 110.

[0073] The gap between the insertion part 121 and the inner wall of the through hole 111 and the gap between the lead-out support 120 and the frame 110 are both sealed by the first sealing member. Through the cooperation of the insertion part 121 and the through hole 111, the lead-out support 120 and the frame 110 are stably connected to improve the stability of the installation of the first sealing member and avoid loosening or falling off of the first sealing member, thereby improving the sealing performance.

[0074] The first sealing member can be sealing glue, sealing gasket, and other types of sealing structures, which are not limited in the present application.

[0075] For example, the shape of the insertion part 121 can be rectangular, parallelogram, isosceles trapezoid, arc, and other types of shapes, as long as the shape of the insertion part 121 is adapted to the contour of the through hole 111, which is not limited in the present application.

[0076] The number of the insertion part 121 can be one or multiple, as long as the insertion part 121 can be inserted and cooperated with the through hole 111, which is not limited in the present application.

[0077] The present application sets the insertion part 121 on the lead-out support 120, and the insertion part 121 is inserted into the through hole 111 of the frame 110, so that the lead-out support 120 and the frame 110 are stably connected to improve the stability of the first sealing member arranged between the insertion part 121 and the frame 110 and between the lead-out support 120 and the frame 110, avoid loosening or falling off of the first sealing member, and thereby improve the sealing performance.

[0078] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , the lead-out support 120 comprises a support body 122.

[0089] Of course, the fastener 125 can also be other types of structures such as a pull rivet nut, as long as it can fix the adapter 130 on the bracket body 122, and the present application does not make too many limitations on this.

[0090] In an embodiment, referring to Figure 2 and Figure 3 As shown, the number of the insertion portions 121 is two, and the two insertion portions 121 are arranged on the opposite sides of the bracket body 122.

[0091] In the above embodiment, the two insertion portions 121 are arranged on the opposite sides of the bracket body 122 and both extend towards the through hole 111. In this way, when installed, the two insertion portions 121 respectively abut against the opposite side walls in the through hole 111, and evenly distribute the load to improve stability.

[0092] In an embodiment, referring to Figure 5 and Figure 6 As shown, the frame 110 includes a frame body 112 and an upper cover 113.

[0093] The through hole 111 is located on the frame body 112, and the upper cover 113 is arranged on the frame body 112. A second sealing member is arranged between the upper cover 113 and the frame body 112.

[0094] The lead-out bracket 120 is arranged on the frame body 112, and the lead-out bracket 120 has a predetermined gap between the lead-out bracket 120 and the upper cover 113 to avoid the second sealing member.

[0095] In the above embodiment, in the battery pack, the cell group 200 can be placed in the frame body 112, and the cell group 200 is packaged in the frame body 112 by the upper cover 113. A second sealing member is arranged between the upper cover 113 and the frame body 112 for sealing.

[0096] Referring to Figure 5As shown, the lead-out support 120 is arranged on one side of the frame body 112, and the upper cover 113 is arranged on the top of the frame body 112. A preset gap is provided between the mounting area of the lead-out support 120 and the mounting area of the upper cover 113 to avoid the second sealing member. In this way, the second sealing member can be arranged in a straight line and smoothly, thereby improving the sealing performance between the upper cover 113 and the frame body 112.

[0097] For example, the second sealing member can be a sealing gasket.

[0098] In an embodiment, referring to Figure 2 , Figure 3 and Figure 7 , the frame body 112 includes a bottom guard plate 1121 and a plurality of side plates arranged around the bottom guard plate 1121.

[0099] The side plates include an inner side plate 1122 and an outer side plate 1123. The inner side plate 1122 and the outer side plate 1123 are connected, and a cavity is formed between the inner side plate 1122 and the outer side plate 1123. The inner side plate 1122 is provided with a first through hole, and the outer side plate 1123 is provided with a second through hole. The first through hole, the second through hole, and part of the cavity form a through hole 111.

[0100] The insertion part 121 is located in the through hole 111 and abuts against the inner side plate 1122 and the outer side plate 1123, respectively.

[0101] In the above embodiment, the lead-out support 120 is arranged on the outer side plate 1123. The insertion part 121 can extend into the through hole 111 formed by the first through hole, the cavity, and the second through hole through the second through hole provided on the outer side plate 1123. The inner side plate 1122 and the outer side plate 1123 abut against the insertion part 121, thereby providing stable support points for the insertion part 121, respectively, to make the installation of the lead-out support 120 more stable.

[0102] The cavity is formed between the inner side plate 1122 and the outer side plate 1123. This arrangement can reduce the overall weight of the side plates and save costs.

[0103] Specifically, referring to Figure 2 , Figure 3 and Figure 7As shown, two first reinforcing ribs 1124 are arranged between the inner side plate 1122 and the outer side plate 1123, and the first reinforcing ribs 1124 are arranged to improve the stability of the connection between the inner side plate 1122 and the outer side plate 1123. The two first reinforcing ribs 1124 divide the cavity into a first cavity 1125, a second cavity 1126 and a third cavity 1127, and the second cavity 1126 is located between the first cavity 1125 and the third cavity 1127. The first through hole on the inner side plate 1122 and the second through hole on the outer side plate 1123 are respectively communicated with the second cavity 1126 to form the through hole 111.

[0104] As shown in Figure 7 As shown, the bottom guard plate 1121 and the upper cover 113 can be arranged on opposite sides of the side plate, the bottom guard plate 1121 is close to the third cavity 1127, and the upper cover 113 is close to the first cavity 1125.

In this way, the mutual interference between the pull rivet nuts on the two sides and the interference between the pull rivet nuts and the insertion part 121 can be avoided, and the installation is affected.

[0105] For example, the side plate formed by the inner side plate 1122, the outer side plate 1123 and the first reinforcing rib 1124 can be an integrally formed piece to improve the connection strength.

[0106] In an embodiment, as shown in Figure 2 , Figure 3 and Figure 7 The frame body 112 is provided with a cross beam 114.

[0107] The cross beam 114 and the side plate provided with the lead-out support 120 surround a lap joint cavity 115, and one end of the connector 130 is located in the lap joint cavity 115 to lap joint the bus bar 300 and the connector 130.
