[0018] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-8 The description includes an auxiliary tooling 100 for a busbar module 10 according to an embodiment of the present invention, in conjunction with... Figure 1 The busbar module 10 includes two busbar structures 11 and a fuse 12. Each busbar structure 11 includes a busbar 110 and multiple insulating elements 111 disposed on the busbar 110. The fuse 12 is detachably disposed between the two busbars 110. The insulating elements 111 are detachably disposed on the side of the busbar 110 away from the fuse 12. Figure 2 The auxiliary tooling 100 for the bus module 10 includes: a first tooling component 20 and a second tooling component 30.

[0019] Specifically, such as Figures 2-6 As shown, the first tooling assembly 20 has a first placement plane 21 and a first positioning hole 22. Part of the insulating component 111 of the busbar module 10 mates with the first positioning hole 22, and part of the conductive busbar 110 of the busbar module 10 mates with the first placement plane 21. The insulating component 111 and the conductive busbar 110 are connected. The second tooling assembly 30 has a second placement plane 31 and a second positioning hole 32. The fuse 12 of the busbar module 10 mates with the second positioning hole 32, and part of the conductive busbar 110 of the busbar module 10 mates with the second placement plane 31. The first tooling assembly 20 and the second tooling assembly 30 are set independently.

[0020] In this embodiment, the combiner cabinet includes multiple combiner modules 10 for current convergence. Each combiner module 10 includes two busbar structures 11 and a fuse 12. Each busbar structure 11 includes a busbar 110 and two insulating members 111 disposed on the busbar 110. The busbar 110 is a copper busbar, and the insulating members 111 are insulators. The first tooling assembly 20 is adapted to assemble two busbar structures 11 respectively. Taking the assembly of one busbar structure 11 as an example, the first tooling assembly 20 includes two first positioning holes 22. First, the two insulating members 111 are placed in the two first positioning holes 22 respectively. Then, the busbar 110 is placed on the first placement plane 21, so that the busbar 110 is disposed on the two insulating members 111. Then, fasteners are used to connect the busbar 110 to the two insulating members 111, thereby realizing the assembly of the busbar structure 11. The assembly of the other busbar structure 11 is similar and will not be described in detail here. The second tooling assembly 30 is adapted to assemble two busbar structures 11 with the fuse 12. First, the fuse 12 is placed in the second positioning hole 32. Then, one of the busbar structures 11 is placed on the side surface of the fuse 12 away from the second tooling assembly 30. The busbar structure 11 is connected to the side surface of the fuse 12 with fasteners. Then, the assembled busbar structure 11 and fuse 12 are flipped so that the busbar structure 11 is placed on the second placement plane 31. Then, the other busbar structure 11 is placed on the other side surface of the fuse 12. Finally, the busbar structure 11 is connected to the other side surface of the fuse 12 with fasteners, thus completing the assembly of the busbar module 10.

[0021] According to the auxiliary tooling 100 for the busbar module 10 of this utility model embodiment, by setting the first tooling component 20, the conductive busbar 110 and the insulating component 111 can be quickly positioned, improving the assembly efficiency and processing accuracy of the conductive busbar structure 11. By setting the second tooling component 30, the fuse 12 and the conductive busbar structure 11 can be quickly positioned, making it easy to connect the two conductive busbar structures 11 to both sides of the fuse 12, thereby realizing the assembly of the busbar module 10. By setting the first tooling component 20 and the second tooling component 30 independently, it is easy to assemble the busbar module 10 in steps, reducing the assembly difficulty of the busbar module 10, improving the assembly efficiency and reliability of the busbar module 10, and improving the assembly quality of the busbar module 10.

[0022] Alternatively, the fastener may be a bolt or a screw.

[0023] Optionally, the first tooling assembly 20 and the second tooling assembly 30 are independently mounted on the operating platform 40.

[0024] According to some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the first tooling assembly 20 includes: a first body portion 23, a portion of the surface of the first body portion 23 being recessed toward the central region of the first body portion 23 to form a first placement plane 21; the first placement plane 21 extends along a first direction A toward at least one side edge of the first body portion 23, and / or, the first placement plane 21 extends along a second direction B toward at least one side edge of the first body portion 23, the first direction A and the second direction B being different.

[0025] In the height direction of the first tooling assembly 20, at least a portion of the surface of the first body portion 23 away from the operating platform 40 is recessed toward the central region of the first body portion 23 to form a first placement plane 21. A first positioning hole 22 is formed on the first body portion 23. The first positioning hole 22 extends along the height direction of the first tooling assembly 20 and opens toward the first placement plane 21. When the insulating member 111 is placed in the first positioning hole 22, the surface of the insulating member 111 away from the operating platform 40 is flush with the first placement plane 21. In this embodiment, the first placement plane 21 extends toward at least one edge of the first body portion 23 along a first direction A, and at the same time, the first placement plane 21 extends toward at least one edge of the first body portion 23 along a second direction B. The first direction A and the second direction B are perpendicular to each other.

[0026] Therefore, by forming a first placement plane 21 on the first body part 23, it is convenient for the conductive bus 110 to be placed on the first placement plane 21, and the side surface of the insulating member 111 away from the operating platform 40 is flush with the first placement plane 21, which facilitates the connection between the conductive bus 110 and the insulating member 111 and improves the assembly efficiency of the conductive bus structure 11.

[0027] Optionally, the first tooling assembly 20 includes two first positioning holes 22, which are spaced apart along the second direction B.

[0028] According to some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the first placement plane 21 is recessed towards the center region of the first body part 23 to form a groove 24. The groove 24 penetrates the side wall of the first body part 23 opposite to the first direction A or the second direction B along the first direction A or the second direction B. The first positioning hole 22 is provided on the bottom wall of the groove 24 and extends towards the center region of the first body part 23.

[0029] In this application, at least a portion of the middle region of the first placement plane 21 is recessed toward the center region of the first body portion 23 in the height direction of the first tooling assembly 20 to form a groove 24. The groove 24 penetrates the sidewalls of the first body portion 23 opposite to each other in the second direction B along the second direction B. A first positioning hole 22 is formed on the bottom wall of the groove 24, and the first positioning hole 22 extends toward the center region of the first body portion 23 in the height direction of the first tooling assembly 20.

[0030] Therefore, by designing the groove 24 on the first body part 23, the contact area between the first body part 23 and the conductive bus 110 can be reduced, thereby improving the flatness of the contact between the conductive bus 110 and the first placement plane 21 and improving the stability of the conductive bus 110 on the first placement plane 21. By setting the first positioning hole 22, the positioning efficiency of the insulating component 111 can be improved, and at the same time, it is convenient to fix the insulating component 111.

[0031] Optionally, such as Figure 5 As shown, at least a portion of the first body portion 23 is recessed towards the central region to form a groove 24, and at least a portion of the first body portion 23 is formed towards the central region to form a first placement plane 21. The first placement plane 21 and the groove 24 are located on the same side of the first body portion 23, and the first placement plane 21 is located on both sides of the groove 24. Thus, the groove 24 and the first placement plane 21 are provided separately, which makes it easier to reduce the flatness requirements of the first placement plane 21 and simplify the process.

[0032] According to some embodiments of this utility model, such as Figures 3-5 As shown, at least a portion of the first body portion 23 is configured as a first retaining edge 25, which is disposed on the outer periphery of the first placement plane 21.

[0033] The first body portion 23 is configured as a first stop 25 along one edge of the first direction A and is disposed on one side of the first placement plane 21 along the first direction A. The first body portion 23 is also configured as a first stop 25 along one edge of the second direction B and is disposed on one side of the first placement plane 21 along the second direction B. Thus, by designing the first stop 25 to be disposed on the outer periphery of the first placement plane 21, the corresponding side of the conductive busbar 110 placed on the first placement plane 21 can be effectively limited. Without the need for manual alignment, the positioning accuracy and efficiency of the conductive busbar 110 can be improved, thereby increasing the yield and reliability of the conductive busbar structure 11 assembly.

[0034] According to some embodiments of this utility model, such as Figures 3-5 As shown, the first tooling assembly 20 further includes an adjustment assembly 26, which is connected to the first body portion 23 at least one side edge, and the adjustment assembly 26 adjusts the width of the first placement plane 21 for placing the conductive busbar 110.

[0035] In this embodiment, the adjustment component 26 is disposed along the first direction A on the side of the first placement plane 21 away from the first stop 25 and connected to the edge of the first body part 23 away from the first stop 25. The adjustment component 26 and the first stop 25 are opposite to each other and spaced apart along the first direction A. At least a part of the adjustment component 26 can move along the first direction A. The adjustment component 26 can adjust the width of the first placement plane 21 for placing the conductive bus 110 in the first direction A. When the conductive bus 110 is placed on the first placement plane 21, the adjustment component 26 and the conductive bus 110 on the side away from the first stop 25 along the first direction A form a cooperation.

[0036] Therefore, by adjusting the setting of component 26, the width of the first placement plane 21 for placing the conductive busbar 110 can be adjusted according to the different specifications of the conductive busbar 110, and manufacturing tolerances can be compensated, improving the adaptability of the first tooling component 20. At the same time, the adjusting component 26 can limit the conductive busbar 110 on the side away from the first stop edge 25 along the first direction A. The adjusting component 26 can work with the first stop edge 25 to fix the conductive busbar 110, preventing the conductive busbar 110 from shaking during the assembly process with the insulating component 111, improving the assembly accuracy of the conductive busbar structure 11, and improving the assembly yield and reliability of the conductive busbar structure 11.

[0037] According to some embodiments of this utility model, such as Figures 3-5 As shown, the adjustment component 26 includes: a first adjustment part 27 and a second adjustment part 28. The first adjustment part 27 is connected to the at least one side edge and is flush with the first placement plane 21. The second adjustment part 28 is movably disposed on the first adjustment part 27 and has multiple adjustment positions. The second adjustment part 28 moves between the multiple adjustment positions.

[0038] The first adjustment part 27 is connected to the edge of the first body part 23 away from the first stop 25, and in the height direction of the first tooling assembly 20, the surface of the first adjustment part 27 away from the operating platform 40 is flush with the first placement plane 21. The second adjustment part 28 is provided on the surface of the first adjustment part 27 away from the operating platform 40 along the height direction of the first tooling assembly 20. The second adjustment part 28 can move towards the first stop 25 in the first direction A, and the second adjustment part 28 can move away from the first stop 25 in the first direction A. After the conductive bus 110 is placed on the first placement plane 21, the second adjustment part 28 is moved to the corresponding adjustment position so that the second adjustment part 28 and the conductive bus 110 stop against each other in the first direction A away from the first stop 25.

[0039] Therefore, by setting the first adjustment part 27, the adjustment component 26 can be fixed to the first body part 23 through the first adjustment part 27. The first adjustment part 27 is flush with the first placement plane 21, which facilitates the movement of the second adjustment part 28 along the first direction A on the first placement plane 21 and the first adjustment part 27. The design of the second adjustment part 28 having multiple adjustment positions makes it easy for the second adjustment part 28 to adjust the width of the first placement plane 21 for placing the conductive busbar 110 according to different specifications of conductive busbar 110, thereby improving the adjustability and flexibility of the second adjustment part 28 and improving the adaptability of the adjustment component 26.

[0040] According to some embodiments of this utility model, such as Figure 4 As shown, both the first adjustment part 27 and the second adjustment part 28 are provided with through holes 29. The through holes 29 of the first adjustment part 27 and the through holes 29 of the second adjustment part 28 are arranged opposite to each other along the height direction of the first body part 23. The fastener is adapted to pass through the corresponding through holes 29 of the first adjustment part 27 and the second adjustment part 28.

[0041] The cross-sectional shape of the through hole 29 on the first adjustment part 27 is circular, and the cross-sectional shape of the through hole 29 on the second adjustment part 28 is oblong. The through holes 29 of the first adjustment part 27 and the through holes 29 of the second adjustment part 28 are arranged opposite each other along the height direction of the first tooling assembly 20. After the second adjustment part 28 is moved to the corresponding adjustment position, the fastener passes through the corresponding positions of the through holes 29 on the first adjustment part 27 and the through holes 29 on the second adjustment part 28 along the height direction of the first tooling assembly 20, thereby fixing the second adjustment part 28 and the first adjustment part 27.

[0042] Therefore, by providing through holes 29 on both the first adjustment part 27 and the second adjustment part 28, it is convenient to form a detachable connection between the first adjustment part 27 and the second adjustment part 28, so as to realize the rapid adjustment of the second adjustment part 28 in multiple adjustment positions, improve the installation efficiency and adjustment efficiency of the adjustment assembly 26, and at the same time, the adjustment assembly 26 can fix the conductive busbar 110.

[0043] According to some embodiments of this utility model, such as Figure 6 As shown, the second tooling assembly 30 includes: a second body portion 33, a portion of the surface of the second body portion 33 being recessed toward the center of the second body portion 33 to form a second placement plane 31; the second placement plane 31 extends along a first direction A toward at least one side edge of the second body portion 33, and / or, the second placement plane 31 extends along a second direction B toward at least one side edge of the second body portion 33.

[0044] In the height direction of the second tooling assembly 30, at least a portion of the surface of the second body portion 33 away from the operating platform 40 is recessed toward the central region of the second body portion 33 to form a second placement plane 31. A second positioning hole 32 is formed on the second body portion 33, extending along the height direction of the second tooling assembly 30 and opening toward the second placement plane 31. In this embodiment, the second placement plane 31 extends toward at least one edge of the second body portion 33 along a first direction A, and simultaneously extends toward at least one edge of the second body portion 33 along a second direction B.

[0045] Therefore, by forming a second placement plane 31 on the second body part 33, the conductive bus 110, which is first connected to the fuse 12, can be flipped and placed on the second placement plane 31. The second body part 33 also has a second positioning hole 32, which facilitates the positioning of the fuse 12 by the second positioning hole 32. This facilitates the connection between the conductive bus structure 11 and the fuse 12 and improves the assembly efficiency of the bus module 10.

[0046] Optionally, the second body portion 33 is configured as a second stop 34 on one side edge along the first direction A and is disposed on one side of the second placement plane 31 along the first direction A. The second body portion 33 is also configured as a second stop 34 on one side edge along the second direction B and is disposed on the second placement plane 31 along the second direction B. Therefore, by designing the second stop 34 to be disposed on the outer periphery of the second placement plane 31, the corresponding side edge of the conductive busbar 110 placed on the second placement plane 31 can be effectively limited, improving the positioning accuracy and efficiency of the conductive busbar 110 without the need for manual alignment.

[0047] According to some embodiments of this utility model, such as Figure 6 As shown, the second body part 33 is provided with a plurality of first positioning holes 22, which are located at opposite ends of the second positioning holes 32. The distance between the plurality of first positioning holes 22 of the second body part 33 is equal to the distance between the plurality of first positioning holes 22 of the first body part 23.

[0048] In this application, the second body part 33 is provided with two first positioning holes 22. The first positioning holes 22 extend toward the central region of the second body part 33 along the height direction of the second tooling assembly 30. The two first positioning holes 22 are respectively provided at both ends of the second positioning holes 32 adjacent to the corresponding edges of the second body part 33 along the second direction B. In the second direction B, the distance between the two first positioning holes 22 of the second body part 33 is equal to the distance between the two first positioning holes 22 of the first body part 23.

[0049] Therefore, by providing multiple first positioning holes 22 on the second body part 33, the insulating part 111 in the conductive bus structure 11, which is first connected to the fuse 12, can be placed in the corresponding first positioning hole 22 after being flipped. The multiple first positioning holes 22, in conjunction with the second placement plane 31, can fix the flipped conductive bus structure 11, effectively improving the positioning efficiency. At the same time, the distance between the multiple first positioning holes 22 of the second body part 33 is equal to the distance between the multiple first positioning holes 22 of the first body part 23, which can further improve the positioning accuracy.

[0050] According to some embodiments of this utility model, such as Figure 7 As shown, the auxiliary tooling 100 for the busbar module 10 further includes a third tooling assembly 35, which has a third placement plane 36. A portion of the conductive busbars 110 of the busbar module 10 cooperates with the third placement plane 36, and the area of ​​the third placement plane 36 is different from the area of ​​the first placement plane 21.

[0051] The third tooling assembly 35 includes a third body portion 38, two first positioning holes 22, an adjustment component 26, and a third stop 37. A portion of the surface of the third body portion 38 is recessed towards its center to form a third placement plane 36. The first positioning holes 22 are formed on the third body portion 38, extending along the height direction of the third tooling assembly 35 and opening towards the third placement plane 36. One edge of the third body portion 38 along the first direction A is constructed as the third stop 37, and it is located on one side of the third placement plane 36 along the first direction A. Another edge of the third body portion 38 along the second direction B is constructed as the third stop 37, and it is located on one side of the third placement plane 36 along the second direction B. The third tooling assembly 35 differs from the first tooling assembly 20 only in size. The first tooling assembly 20, the second tooling assembly 30, and the third tooling assembly 35 are independently provided.

[0052] In this application, the area of ​​the third placement plane 36 is larger than the area of ​​the first placement plane 21, combined with Figure 8The busbar module 10 includes two conductive busbar structures 11 of different sizes, namely a first conductive busbar structure 13 and a second conductive busbar structure 14. In the first direction A, the width of the conductive busbar 110 in the first conductive busbar structure 13 is greater than the width of the conductive busbar 110 in the second conductive busbar structure 14. The size of the third tooling assembly 35 is adapted to the first conductive busbar structure 13, and the size of the first tooling assembly 20 is adapted to the second conductive busbar structure 14. After the first conductive busbar structure 13 and the second conductive busbar structure 14 are assembled by the third tooling assembly 35 and the first tooling assembly 20 respectively, the fuse 12 is first placed in the second positioning hole 32 of the second tooling assembly 30, and then the conductive busbar 110 of the first conductive busbar structure 13 is moved away from the corresponding insulating component 111. One side surface of the first conductive busbar structure 13 is placed on the side surface of the fuse 12 away from the second tooling assembly 30. The conductive busbar 110 of the first conductive busbar structure 13 is connected to one side surface of the fuse 12 with fasteners. Then, the assembled first conductive busbar structure 13 and fuse 12 are flipped so that the insulating part 111 of the first conductive busbar structure 13 is placed in the corresponding first positioning hole 22 and the conductive busbar 110 of the first conductive busbar structure 13 is placed on the second placement plane 31. Then, the side surface of the conductive busbar 110 of the second conductive busbar structure 14 away from the corresponding insulating part 111 is placed on the other side surface of the fuse 12. The conductive busbar 110 of the second conductive busbar structure 14 is connected to the other side surface of the fuse 12 with fasteners. The assembly of the busbar module 10 is then completed.

[0053] Optionally, when the two conductive bus structures 11 are the same size, the two conductive bus structures 11 can be assembled from the same first tooling assembly 20 or the same third tooling assembly 35.

[0054] According to some embodiments of the present invention, the area of ​​the second placement plane 31 is larger than the area of ​​the first placement plane 21. The second placement plane 31 is used to place the conductive busbar 110 of the first conductive busbar structure 13, and the area of ​​the second placement plane 31 is larger than the area of ​​the first placement plane 21 used to place the conductive busbar 110 in the second conductive busbar structure 14. Therefore, by designing the second placement plane 31 to have a larger area, when assembling the busbar module 10, the larger conductive busbar structure 11 is positioned below the smaller conductive busbar structure 11 in the height direction of the second tooling assembly 30, which can improve the stability and reliability of the assembly of the busbar module 10.
