[0028] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0029] Reference Figure 1 A schematic diagram of the terminal structure described in an embodiment of this utility model is shown; refer to Figure 2 The diagram shows a schematic of the terminal being installed on a copper busbar in an embodiment of this utility model.

[0030] like Figure 1 and Figure 2As shown in the figure, this utility model embodiment discloses a battery pack, which includes a battery pack body, terminals, a copper busbar 40, and a connecting wire 50. The copper busbar 40 is disposed on the battery pack body, and the terminals are detachably connected to the copper busbar 40. The battery pack has intersecting first direction X, second direction Y, and third direction Z, and the copper busbar 40 extends along the third direction Z. The terminals include a terminal body 10 and a connecting portion 20. The terminal body 10 extends along the first direction X and is attached to the surface of the copper busbar 40. The connecting portion 20 is disposed on the side of the terminal body 10 away from the surface of the copper busbar 40 and protrudes from the terminal body 10 along the second direction Y. The connecting portion 20 extends along the third direction Z and is connected to the connecting wire 50.

[0031] This utility model discloses a battery pack, which includes a battery pack body, terminals, a copper busbar 40, and connecting wires 50. The copper busbar 40 is disposed on the battery pack body and serves as a connector for the battery pack body, allowing it to be connected to an external circuit. The terminals are detachably connected to the copper busbar 40, connecting the battery pack body to the external circuit via the terminals and the copper busbar 40. For example, a first through hole 11 can be provided on the terminal body 10, and a second through hole 41 can be provided on the copper busbar 40. Bolts are inserted into the first through hole 11 and the second through hole 41 to detachably connect the terminals to the copper busbar 40. A first snap-fit ​​component can be provided on the terminal body 10, and a second snap-fit ​​component can be provided on the copper busbar 40. The first snap-fit ​​component is snapped into the second snap-fit ​​component, thereby snapping the terminal body 10 into the copper busbar 40.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the copper busbar 40 extends along a third direction Z, and the first direction X and the second direction Y intersect at the third direction Z. Exemplarily, the first direction X is perpendicular to the third direction Z, and the second direction Y is perpendicular to both the first direction X and the third direction Z. Of course, the first direction X can also intersect the third direction Z, and the angle between the first direction X and the third direction Z is close to 90 degrees; similarly, the second direction Y can intersect both the first direction X and the third direction Z, and the angle between the second direction Y and the first direction X is close to 90 degrees, as is the angle between the second direction Y and the third direction X. This embodiment of the present invention does not impose specific limitations on these aspects; in practical applications, those skilled in the art can configure the settings as needed.

[0033] The following description will use the example of a copper busbar 40 extending along a third direction Z, with a first direction X perpendicular to the third direction Z and a second direction Y perpendicular to both the first direction X and the third direction Z, to illustrate the embodiments of this utility model.

[0034] like Figure 1 and Figure 2As shown, the terminal in this embodiment of the present invention includes a terminal body 10 and a connecting portion 20. The terminal body 10 has a sheet-like structure and is attached to the surface of the copper busbar 40, and the terminal body 10 extends along a first direction X. That is, the copper busbar 40 extends along a third direction Z, the terminal body 10 extends along the first direction X, the terminal body 10 is attached to the surface of the copper busbar 40, and is detachably connected to the copper busbar 40.

[0035] A connecting portion 20 is provided on the side of the terminal body 10 away from the copper busbar 40. The connecting portion 20 protrudes from the terminal body 10 along the second direction Y and extends along the third direction Z. During battery pack installation, the terminal body 10 can be attached to the surface of the copper busbar 40, and then the connecting wire 50 can be connected to the connecting portion 20. After the connecting wire 50 is installed, the connecting portion 20 will not protrude from the outside of the terminal body 10 along the first direction X, avoiding interference between the connecting portion 20 and other components of the battery pack. This helps reduce the space required for the connecting wire 50, thereby improving the space utilization of the battery pack. Furthermore, it also prevents the connecting wire 50 from overlapping with other components of the battery pack, which could cause a short circuit and affect the reliability of the battery pack.

[0036] It should be noted that, in this embodiment of the present invention, along the second direction Y, the terminal body 10 has a first surface and a second surface that are disposed opposite to each other. The first surface is attached to the surface of the copper busbar 40, the connecting part 20 is connected to the second surface, and the connecting part 20 protrudes from the terminal body 10 along the second direction Y.

[0037] In this embodiment of the invention, the connecting part 20 can be a snap-fit ​​part, into which the connecting wire 50 is snapped to secure it. Alternatively, the connecting part 20 can be a through hole, into which the connecting wire 50 is secured by a strap. Of course, in this embodiment of the invention, the specific structure of the connecting part 20 is not limited in many ways; in practical applications, those skilled in the art can design it as needed.

[0038] In this embodiment of the invention, a connecting portion 20 is provided on the side of the terminal body 10 away from the copper busbar 40. The connecting portion 20 protrudes from the terminal body 10 along the second direction Y and extends along the third direction Z. The connecting portion 20 connects to the connecting wire 50 to fix the connecting wire 50, and ensures that at least a portion of the projection of the connecting wire 50 on the plane of the terminal body 10 falls within the terminal body 10. This prevents the connecting wire 50 from protruding outward from the terminal body 10 along the first direction X after being connected to the connecting portion 20, thus avoiding interference with other components of the battery pack. This helps reduce the arrangement space of the connecting wire 50 and improves the space utilization of the battery pack. Furthermore, the above arrangement also prevents the connecting wire 50 from extending out of the terminal body 10 along the first direction X and overlapping with other components of the battery pack, which could cause a short circuit in the battery pack and affect its reliability.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting part 20 in this embodiment of the present invention includes a first snap-fit ​​part 21. Along the second direction Y, the first snap-fit ​​part 21 is disposed on the side of the terminal body 10 away from the surface of the copper busbar 40, and the first snap-fit ​​part 21 snaps the connecting wire 50.

[0040] like Figure 1 and Figure 2 As shown, the connecting portion 20 in this embodiment of the present invention includes a first snap-fit ​​portion 21, which is disposed along the second direction Y on the side of the terminal body 10 away from the surface of the copper busbar 40. That is, along the second direction Y, the terminal body 10 has a first surface and a second surface disposed opposite to each other. The first surface of the terminal body 10 is attached to the surface of the copper busbar 40, and the first snap-fit ​​portion 21 protrudes from the second surface of the terminal body 10 along the second direction Y, extending along the third direction Z. The connecting wire 50 is snapped into the first snap-fit ​​portion 21 to fix the connecting wire 50.

[0041] In this embodiment of the invention, a first latching portion 21 is provided on the second surface of the terminal body 10. The first latching portion 21 protrudes from the terminal body 10 along the second direction Y, and latches the connecting wire 50 to secure it. Furthermore, the first latching portion 21 extends along the third direction Z. By latching the connecting wire 50 with the first latching portion 21, it prevents the connecting wire 50 from protruding outwards from the terminal body 10 along the first direction X after being connected to the first latching portion 21, thus avoiding interference with other components of the battery pack. This helps reduce the space required for the connecting wire 50 and improves the space utilization of the battery pack.

[0042] It should be noted that, in this embodiment of the present invention, the first connecting part 21 can be integrally formed with the terminal body 10, the first connecting part 21 can be welded to the second surface of the terminal body 10, or the first connecting part 21 can be snapped onto the terminal body 10. In this embodiment of the present invention, there are no excessive restrictions on the specific connection method between the first connecting part 21 and the terminal body 10. In practical applications, technicians can set it as needed.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting part 20 in this embodiment of the present invention further includes a first support part 22. Along the second direction Y, the first support part 22 and the first snap-fit ​​part 21 are disposed on the same side of the terminal body 10; and the first support part 22 and the first snap-fit ​​part 21 are spaced apart along the third direction Z. The first support part 22 supports the connecting line 50.

[0044] like Figure 1 and Figure 2 As shown, the connecting portion 20 in this embodiment of the present invention further includes a first support portion 22, which is disposed on the same side of the terminal body 10 along the second direction Y as the first snap-fit ​​portion 21. It can be understood that the first surface of the terminal body 10 is attached to the surface of the copper busbar 40, and both the first support portion 22 and the first snap-fit ​​portion 21 are disposed on the second surface of the terminal body 10. Both the first support portion 22 and the first snap-fit ​​portion 21 protrude from the terminal body 10 along the second direction Y. The first snap-fit ​​portion 21 and the first support portion 22 are spaced apart along the third direction Z, and the first support portion 22 is disposed on the side of the first snap-fit ​​portion 21 near the side from which the connecting line 50 extends.

[0045] In this embodiment of the invention, a first support portion 22 is provided on the second surface of the terminal body 10. The first support portion 22 and the first snap-fit ​​portion 21 are disposed on the same side of the terminal body 10 along the second direction Y. The first support portion 22 supports the connecting wire 50 to prevent the connecting wire 50 from shifting, and the first snap-fit ​​portion 21 snaps the connecting wire 50 in place to secure it. Furthermore, the support of the connecting wire 50 by the first support portion 21 also helps to improve the reliability of the connection between the connecting wire 50 and the external circuit, preventing the connecting wire 50 from falling off and causing a short circuit in the battery pack.

[0046] It should be noted that, in this embodiment of the present invention, the first support portion 22 can be integrally formed with the terminal body 10, the first support portion 22 can be welded to the second surface of the terminal body 10, or the first support portion 22 can be snapped onto the terminal body 10. In this embodiment of the present invention, there are no excessive restrictions on the specific connection method between the first support portion 22 and the terminal body 10. In practical applications, technicians can set it as needed.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the battery pack in this embodiment of the present invention also includes an anti-rotation part 30. Along the second direction Y, the anti-rotation part 30, the first snap-fit ​​part 21 and the first support part 22 are disposed on the opposite side of the terminal body 10. The anti-rotation part 30 is snapped onto the side of the copper busbar 40 to limit the terminal body 10.

[0048] like Figure 1 and Figure 2As shown in this embodiment of the invention, along the second direction Y, an anti-rotation part 30 is provided on the opposite side of the terminal body 10 and the first snap-fit ​​part 21 and the first support part 22. The anti-rotation part 30 snaps onto the side of the copper busbar 40, limiting the terminal body 10 so that it can be attached to a suitable position on the copper busbar 40 for terminal installation. Furthermore, the anti-rotation part 30 eliminates the need for additional tooling fixtures to fix the terminal body 10 during battery pack installation, thereby improving the terminal installation efficiency.

[0049] It should be noted that the anti-rotation part 30 in this embodiment of the present invention can be integrally formed with the terminal body 10. The anti-rotation part 30 can be welded to the first surface of the terminal body 10, or the anti-rotation part 30 can be snapped onto the terminal body 10. In this embodiment of the present invention, there are no excessive restrictions on the specific connection method between the anti-rotation part 30 and the terminal body 10. In practical applications, technicians can set it as needed.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, along the first direction X, the terminal body 10 has a first end and a second end that are disposed opposite to each other, and the terminal body 10 is detachably connected to the copper busbar 40 near the second end; the connecting part 20 and the anti-rotation part 30 are both disposed near the first end of the terminal body 10.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the terminal body 10 has a first end and a second end disposed opposite to each other along the first direction X. That is, the terminal body 10 has a first end and a second end disposed opposite to each other along its extending direction.

[0052] The terminal body 10 has a first through hole 11 near the second end, and the copper busbar 40 has a second through hole 41. The first through hole and the second through hole are arranged opposite to each other along the second direction Y. A bolt passes through the first through hole 11 and the second through hole 41 to detachably connect the terminal body 10 to the copper busbar 40.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment of the present invention, both the connecting portion 20 and the anti-rotation portion 30 are disposed on the terminal body 10 near the first end. It can be understood that, along the second direction Y, the anti-rotation portion 30 protrudes from the first surface of the terminal body 10, and the connecting portion 20 protrudes from the second surface of the terminal body 10.

[0054] In this embodiment of the invention, by placing the anti-rotation part 30 near the first end of the terminal body 10, the anti-rotation part 30 can be snapped onto the side of the copper busbar 40 during the process of attaching the terminal body 10 to the copper busbar 40, thereby limiting the terminal and facilitating terminal installation, which also helps to improve the installation efficiency of the terminal. Furthermore, the connecting part 20 is placed near the first end of the terminal body 10, which can avoid the first through hole 11 placed near the second end of the terminal body 10, and also facilitates the direct bending of the portion of the terminal body 10 near the first end to form the connecting part 20 and the anti-rotation part 30.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, along the third direction Z, the anti-rotation part 30 is disposed on the side of the first snap-fit ​​part 21 away from the first support part 22.

[0056] like Figure 1 and Figure 2 As shown in the present invention embodiment, along the third direction Z, the anti-rotation part 30 is disposed on the side of the first snap-fit ​​part 21 away from the first support part 22, so that the first support part 22, the first snap-fit ​​part 21 and the anti-rotation part 30 are arranged in sequence at the position of the terminal body 10 near the first end, so as to avoid mutual interference between the first support part 22, the first connection part 21 and the anti-rotation part 30 during the setting process.

[0057] Furthermore, along the third direction Y, the first support portion 22, the first snap-fit ​​portion 21 and the anti-rotation portion 30 are arranged in sequence, so as to form the first support portion 22, the first snap-fit ​​portion 21 and the anti-rotation portion 30 by bending the first end of the terminal body 10, thereby simplifying the terminal manufacturing process and reducing the terminal manufacturing cost.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, in this embodiment of the present invention, at least one of the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30 is integrally formed with the terminal body 10.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the first snap-fit ​​portion 21 can be integrally formed with the terminal body 10, the first support portion 22 can be integrally formed with the terminal body 10, and the anti-rotation portion 30 can also be integrally formed with the terminal body 10. It can be understood that the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30 can all be integrally formed with the terminal body 10, or one of the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30 can be integrally formed with the terminal body 10, or two of the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30 can be integrally formed with the terminal body 10.

[0060] In this embodiment of the present invention, at least one of the first snap-fit ​​portion 21, the first support portion 22 and the anti-rotation portion 30 is integrally formed with the terminal body 10 to simplify the terminal manufacturing process and avoid multiple processing steps during the terminal manufacturing process, which would result in excessively high terminal manufacturing costs.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the first snap-fit ​​part 21, the first support part 22 and the anti-rotation part 30 are all formed by bending a part of the terminal body 10.

[0062] like Figure 1 and Figure 2 As shown, during the terminal processing, the terminal body 10 can be formed by stamping. During the stamping process, three bending portions are formed near the first end of the terminal body 10. After stamping, the three bending portions are bent to form the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30. This design further simplifies the terminal manufacturing process and avoids multiple processing steps that would otherwise lead to excessively high manufacturing costs.

[0063] Furthermore, by bending the terminal body 10 itself to form the first snap-fit ​​portion 21, the first support portion 22, and the anti-rotation portion 30, it helps to reduce the length of the terminal body 10 along the first direction X, so that the space occupied by the terminal body 10 along the first direction X is smaller, thereby helping to improve the space utilization of the battery pack.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the terminal body 10 is provided with a first through hole 11, the copper busbar 40 is provided with a second through hole 41, and the battery pack also includes a connector, which passes through the first through hole 11 and the second through hole 41 to detachably connect the terminal body 10 to the copper busbar 40.

[0065] like Figure 1 and Figure 2 As shown, a first through hole 11 is provided on the terminal body 10. The first through hole 11 is located near the second end of the terminal body 10, or the first through hole 11 is located in the middle of the terminal body 10. A second through hole 41 is also provided on the copper busbar 40. The connector passes through the first through hole 11 and the second through hole 41 to detachably connect the terminal body 10 to the copper busbar 40. Exemplarily, the connector in this embodiment of the present invention can be a bolt.

[0066] Of course, the above are just individual examples of the terminal body 10 being detachably connected to the copper busbar 40, and are not intended to limit the present invention. In practical applications, those skilled in the art can also configure the terminal body 10 to be detachably connected to the copper busbar 40 as needed.

[0067] In this embodiment of the invention, a first through hole 11 is provided on the terminal body 10, and a second through hole 41 is provided on the copper busbar 40. A connector is inserted into the first through hole 11 and the second through hole 41, thereby detachably connecting the terminal body 10 to the copper busbar 40 via the connector. This simplifies the method of detachably connecting the terminal body 10 to the copper busbar 40, thereby helping to further simplify the terminal installation process and reduce the production cost of the battery pack.

[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, the battery pack in this embodiment of the present invention also includes a connecting wire 50, which extends at least partially along the third direction Z and is snapped into the connecting portion 20.

[0069] In this embodiment of the present invention, by extending at least part of the connecting wire 50 along the third direction Z and snapping it into the connecting part 20, the connecting wire 50 is prevented from extending out of the terminal body 10 along the first direction X and interfering with other components of the electronic device, thereby helping to improve the space utilization of the battery pack.

[0070] Furthermore, the above-mentioned arrangement can also prevent the connecting wire 50 from extending out of the terminal body 10 along the first direction X and overlapping with other components of the battery pack, which would cause a short circuit in the battery pack and affect the reliability of the battery pack.

[0071] In some embodiments, such as Figure 2 As shown, along the second direction Y, the projection of the connecting portion 20 onto the plane where the terminal body 10 is located falls into the terminal body 10; along the second direction Y, at least a portion of the connecting line 50 onto the plane where the terminal body 10 is located falls into the terminal body 10.

[0072] In this embodiment of the invention, the projection of the connecting portion 20 along the second direction Y onto the plane of the terminal body 10 is configured to fall within the terminal body 10, and at least a portion of the connecting wire 50 along the second direction Y onto the plane of the terminal body 10 is configured to fall within the terminal body 10. When the connecting wire 50 is connected to the connecting portion 20, the connecting wire 50 will not protrude beyond the outer side of the terminal body 10 along the first direction X, thus avoiding interference with other components of the battery pack, thereby improving the space utilization of the battery pack. Furthermore, the connecting wire 50 is less likely to overlap with other components of the battery pack, preventing short circuits and affecting the reliability of the battery pack. This utility model discloses a battery pack, which includes a battery pack body, terminals, copper busbars, and connecting wires. The copper busbars are disposed on the battery pack body, and the terminals are detachably connected to the copper busbars. The battery pack has intersecting first, second, and third directions, and the copper busbars extend along the third direction. Each terminal includes a terminal body and a connecting portion. The terminal body extends along the first direction and is attached to the surface of the copper busbar. The connecting portion is disposed on the side of the terminal body away from the surface of the copper busbar and protrudes from the terminal body along the second direction. The connecting portion extends along the third direction and is connected to the connecting wires.

[0073] In this embodiment of the invention, a connecting portion is provided on the side of the terminal body away from the copper busbar. The connecting portion protrudes from the terminal body in a second direction and extends in a third direction. A connecting wire is connected through the connecting portion to fix the connecting wire, and at least a portion of the projection of the connecting wire on the plane of the terminal body falls into the terminal body. This prevents the connecting wire from protruding outwards from the terminal body in the first direction after being connected to the connecting portion, thus avoiding interference with other components and improving the space utilization of the battery pack. Furthermore, the above arrangement can also prevent the connecting wire from overlapping with other components of the battery pack, which could lead to a short circuit and affect the reliability of the battery pack.
