[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] The following is a reference appendix. Figure 1-4 The output pole assembly 100 according to an embodiment of the present utility model is described.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The output electrode assembly 100 according to an embodiment of the present utility model includes: a high-voltage connector 10, an output electrode base 20, and a copper busbar 30.

[0034] Specifically, the high-voltage connector 10 has a high-voltage output terminal 11; the output electrode base 20 includes a body 21 and a limiting member 22, the limiting member 22 is fixed to the body 21, and the limiting member 22 is snapped into the high-voltage output terminal 11 to restrict the output electrode base 20 from rotating relative to the high-voltage connector 10; the copper busbar 30 is electrically connected to the high-voltage output terminal 11 inside the body 21.

[0035] For example, such as Figure 1 , Figure 2 and Figure 3 As shown, the high voltage connector 10 has a high voltage output terminal 11 at its front end, the body 21 of the output electrode base 20 is formed into a rectangular shell structure, the limiting member 22 is connected to the outer surface of the body 21, and the copper busbar 30 extends into the body 21 and is electrically connected to the high voltage output terminal 11.

[0036] When using the output electrode assembly 100 to connect the copper busbar 30 to the high voltage output terminal 11, first connect the high voltage output terminal 11 to the limiting member 22, and then insert one end of the copper busbar 30 into the body 21 and electrically connect it to the high voltage output terminal 11.

[0037] The output electrode assembly 100 of this utility model has a limiting member 22 on the body 21. The limiting member 22 is snapped into the high-voltage output terminal 11, which can fix the output electrode base 20 on the high-voltage connector 10. When the copper busbar 30 is connected to the high-voltage output terminal 11, it can effectively prevent the output electrode base 20 from rotating relative to the high-voltage connector 10, thereby facilitating the connection between the copper busbar 30 and the high-voltage connector 10, reducing assembly difficulty, saving connection time and improving connection efficiency. At the same time, compared with the existing technology of setting an anti-rotation bracket on the high-voltage connector 10, the anti-rotation bracket is large in size and occupies a large space in the battery pack. The limiting member 22 of the output electrode assembly 100 of this application has a simple structure and small size, thereby reducing the space occupied by the output electrode assembly 100 in the battery pack, effectively improving the space utilization rate in the battery pack. In addition, it can also reduce the use of parts and reduce production costs.

[0038] Furthermore, the output terminal base 20 can provide insulation protection for the connection 211 between the copper busbar 30 and the high-voltage output terminal 11, thereby effectively preventing liquid from splashing onto the connection 211 between the copper busbar 30 and the high-voltage output terminal 11, thus ensuring the stability of the connection between the copper busbar 30 and the high-voltage output terminal 11, and thus ensuring the safety of the battery pack.

[0039] According to the embodiment of the present invention, the output electrode assembly 100 has a limiting member 22 on the body 21. The limiting member 22 is snapped into the high voltage output terminal 11. When the copper busbar 30 is connected to the high voltage output terminal 11, it can effectively prevent the output electrode base 20 from rotating relative to the high voltage connector 10, thereby facilitating the connection between the copper busbar 30 and the high voltage connector 10 and improving the space utilization rate inside the battery pack.

[0040] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The limiting member 22 is located on one side of the main body 21 (e.g., Figure 2 The lower side of the body 21 shown), one end of the limiting member 22 (as shown) Figure 2The upper end of the limiting member 22 shown is connected to the body 21, and the other end of the limiting member 22 (as shown) is connected to the body 21. Figure 2 The lower end of the limiting member 22 shown extends away from the body 21. There are multiple limiting members 22, that is, there can be two, three or four or more limiting members 22. Multiple limiting members 22 define the limiting groove. The high voltage output end 11 is formed into a cuboid and extends into the limiting groove.

[0041] In this way, the limiting component 22 is positioned reasonably and will not occupy the space where the copper busbar 30 extends into the body 21, thus facilitating the assembly of the copper busbar 30. At the same time, multiple limiting components 22 together define the limiting groove. When the high voltage output terminal 11 extends into the limiting groove, it can effectively prevent the high voltage output terminal 11 from detaching from the limiting groove, thereby ensuring the connection stability between the output electrode base 20 and the high voltage connector 10.

[0042] For example, such as Figure 2 and Figure 3 As shown, the limiting member 22 is located on the lower side of the body 21. The upper end of the limiting member 22 is connected to the body 21, and the lower end of the limiting member 22 extends downward. There are four limiting members 22, which are arranged at intervals on the body 21. The four limiting members 22 define the limiting groove. The front end of the high voltage output terminal 11 extends into the limiting groove and engages with the limiting member 22.

[0043] According to some optional embodiments of the present invention, refer to Figure 2 The limiting member 22 includes a first limiting member 221, which is located at the end of the high-voltage output terminal 11 and abuts against the edge of the end of the high-voltage output terminal 11. Therefore, the first limiting member 221 can effectively restrict the movement of the high-voltage output terminal 11 within the limiting groove, thereby ensuring the connection stability between the output electrode base 20 and the high-voltage connector 10.

[0044] For example, such as Figure 2 As shown, the first limiting member 221 is provided at the front end of the high voltage output terminal 11. The front end of the high voltage output terminal 11 has two edges, and the two edges abut against the corresponding first limiting member 221.

[0045] Furthermore, such as Figure 2 As shown, the first limiting member 221 extends in an arc shape along the end edge of the high voltage output terminal 11. Therefore, during the process of the high voltage output terminal 11 and the first limiting member 221 engaging, the arc-shaped first limiting member 221 can reduce the collision force between the high voltage output terminal 11 and the first limiting member 221, thereby avoiding damage to the first limiting member 221 and ensuring the service life of the first limiting member 221.

[0046] According to some embodiments of this utility model, refer to Figure 2The limiting member 22 includes: a second limiting member 222, and the number of second limiting members 222 is multiple, that is, the number of second limiting members 222 is two, three, four or more, and the multiple second limiting members 222 are arranged in the width direction of the high voltage output terminal 11 (e.g., Figure 2 The high voltage output terminal 11 is shown on both sides in the left and right directions. Thus, the second limiting member 222 can limit the high voltage output terminal 11 in the width direction, thereby further preventing the high voltage output terminal 11 from disengaging from the limiting groove. At the same time, the second limiting member 222 cooperates with the first limiting member 221 to effectively ensure the connection stability between the output electrode base 20 and the high voltage connector 10.

[0047] For example, such as Figure 2 As shown, there are two second limiting members 222, which are respectively arranged on the left and right sides of the high voltage output terminal 11.

[0048] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The main body 21 is provided with a connecting part 211, and a plug-in interface is formed in the connecting part 211. One end of the copper busbar 30 (e.g. Figure 3 The right end of the copper busbar 30 shown passes through the plug-in interface and is electrically connected to the high-voltage output terminal 11. Therefore, the connection part 211 facilitates the arrangement of the plug-in interface, eliminating the need for additional structures to arrange the interface, thus reducing the number of components. Furthermore, the plug-in connection method is simple and easy to operate, facilitating the installation of the copper busbar 30 and the output electrode base 20.

[0049] For example, such as Figure 2 and Figure 3 As shown, the left end of the main body 21 is provided with a connecting part 211, and a rectangular plug-in interface is formed inside the connecting part 211. The right end of the copper busbar 30 passes through the plug-in interface and is electrically connected to the high voltage output terminal 11 inside the main body 21.

[0050] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The output electrode assembly 100 includes a binding member 40, which is arranged circumferentially around the connecting portion 211. The binding member 40 is used to fix the copper busbar 30 to the connecting portion 211. Therefore, the binding member 40 can ensure the connection strength between the copper busbar 30 and the output electrode base 20, effectively preventing the copper busbar 30 from separating from the output electrode base 20, thereby ensuring the reliability of the copper busbar 30 and the output electrode base 20. Preferably, the binding member 40 is a cloth-based adhesive tape, which is simple to obtain, inexpensive, and easy to use in batches.

[0051] According to some embodiments of this utility model, refer to Figure 3 and Figure 4The output terminal assembly 100 includes a fastener 50. The body 21 has a mounting port through which the fastener 50 electrically connects the copper busbar 30 to the high-voltage output terminal 11. Thus, the fastener 50 prevents the copper busbar 30 from rotating relative to the high-voltage output terminal 11, ensuring the stability of the connection between the copper busbar 30 and the high-voltage output terminal 11. Simultaneously, the fastener 50 electrically connects the copper busbar 30 to the high-voltage output terminal 11, thereby serving both a fixing function and an electrical connection function, thus improving the functional integration of the fastener 50.

[0052] In addition, the fastener 50 can be supplied as a complete component with the copper busbar 30, without the need for additional structural fixing of the copper busbar 30 and the high-voltage output terminal 11. This can effectively avoid the production time increase caused by the mismatch between the arbitrarily configured fastener 50 and the copper busbar 30, thereby saving the connection time between the copper busbar 30 and the high-voltage output terminal 11 and improving the connection efficiency.

[0053] For example, such as Figure 3 and Figure 4 As shown, the fastener 50 extends in the vertical direction, and part of the fastener 50 is located inside the body 21. The fastener 50 passes through the copper busbar 30 and the high voltage output terminal 11 from top to bottom.

[0054] According to some optional embodiments of the present invention, refer to Figure 1 and Figure 2 The output terminal assembly 100 includes a protective cover 60, which is connected to the main body 21 and seals the mounting opening. Thus, the protective cover 60 provides insulation protection for the fasteners 50 inside the main body 21, the copper busbars 30 fixed by the fasteners 50, and the high-voltage output terminal 11, thereby ensuring the safety of the internal structure of the output terminal base 20 and consequently ensuring the safe use of the battery pack.

[0055] According to some optional embodiments of the present invention, refer to Figure 4 The output electrode assembly 100 includes a connector 70, which is disposed between the protective cover 60 and the body 21. The protective cover 60 is connected to the body 21 via the connector 70. Thus, the connector 70 connects the protective cover 60 and the body 21 into a single unit, preventing the protective cover 60 from being lost. Simultaneously, the protective cover 60 is fixed to the body 21 via the connector 70. This fixing method is simple and easy to process, thereby facilitating the production of the output electrode base 20.

[0056] Preferably, the output electrode base 20 is integrally injection molded, which can save production time of the output electrode base 20 and improve production efficiency.

[0057] According to the battery pack of the second aspect embodiment of the present utility model, referring to... Figure 1 , Figure 2 and Figure 3 This includes the output pole component 100 of the first aspect of this embodiment.

[0058] According to the battery pack of the present invention, by setting the output electrode assembly 100 of the first aspect embodiment above, a limiting member 22 is provided on the body 21. The limiting member 22 is snapped into connection with the high voltage output terminal 11. When the copper busbar 30 is connected to the high voltage output terminal 11, the output electrode base 20 can be effectively prevented from rotating relative to the high voltage connector 10, thereby facilitating the connection between the copper busbar 30 and the high voltage connector 10, and also improving the space utilization rate inside the battery pack.
