[0040] Example 1

[0041] This embodiment provides a copper busbar assembly, as shown in the attached figure. Figures 1-6 As shown, it includes:

[0042] The first component 11 has at least two conductive elements. The number of conductive elements can be adjusted according to actual needs, and can be two, three, or even more.

[0043] The second component 12 is connected to the first component 11. Specifically, this connection refers to a fixed connection. In this embodiment, the first component 11 is located above the second component 12, achieving a locking and fixing effect. A conductive element extends downwards through the second component 12, extending vertically downwards. The first component 11 and the second component 12 cooperate to form a fixing cavity 111.

[0044] The magnetic core 13 is housed in the fixed cavity 111, and the conductive element passes through the magnetic core 13. The magnetic core 13 has a ring structure, which is existing technology, so it will not be described in detail in this embodiment.

[0045] The isolator 14 is connected to the second component 12 and is located below the second component 12. The isolator 14 separates two adjacent conductive components to ensure electrical clearance between them and prevent creepage during use. The magnetic core 13 cooperates with the fixing cavity 111 to form a potting area. This potting area can be an upper opening, a side opening, or a lower opening. In this embodiment, the upper opening is used as an example. The potting area is filled with glue 15, which enters from the upper opening to form a potting seal. The upper opening is specifically located on the top surface of the fixing cavity 111. By using the first component 11 and the second component 12 in cooperation, the overall volume is reduced compared to a single plastic part in the prior art, thus reducing the space occupied. Secondly, the potting seal improves the overall protection level.

[0046] Specifically, as shown in the attached document Figures 1-2 As shown, one of the first component 11 and the second component 12 is provided with a buckle 16, and the other of the first component 11 and the second component 12 is provided with a slot 17 that mates with the buckle 16. The buckle 16 and the slot 17 mate to achieve the connection and fixation effect between the first component 11 and the second component 12, and secondly, to reduce the assembly difficulty and make installation more convenient. When the first component 11 is provided with the buckle 16, the second component 12 is provided with the slot 17; conversely, when the first component 11 is provided with the slot 17, the second component 12 is provided with the buckle 16. Here, one buckle 16 and one slot 17 form a set of buckle structures. The first component 11 and the second component 12 can be fixed by a set of buckle structures, that is, one end of the two components is hinged, and the other end is fixed by a buckle structure. The first component 11 and the second component 12 can also be fixed by two sets of buckle structures, that is, both ends of the two components are fixed by buckle structures. The first component 11 and the second component 12 can also achieve the fixing effect by three or more sets of buckle structures. Those skilled in the art can adjust the position of the buckle structures according to actual needs. In addition, bolt fastening or riveting can also be used.

[0047] Specifically, as shown in the attached document Figures 1-2As shown, one of the first component 11 and the second component 12 is provided with a positioning post 18, and the other of the first component 11 and the second component 12 is provided with a positioning hole 19 that mates with the positioning post 18. The positioning post 18 and the positioning hole 19 mate to form a positioning fit. When the first component 11 is provided with the positioning post 18, the second component 12 is provided with the positioning hole 19; conversely, the first component 11 is provided with the positioning hole 19, and the second component 12 is provided with the positioning post 18. One positioning post 18 and one positioning hole 19 form a positioning structure. The positioning structure can be one set, or two or more sets. The positioning structure can also be staggered. For example, the first component 11 is provided with one positioning post 18 and one positioning hole 19, and the second component 12 is provided with a corresponding structure, forming two sets of positioning effects.

[0048] Specifically, as shown in the attached document Figure 4 As shown, the system also includes a first connector 20, a second connector 21, and three conductive elements: a first conductive element 22, a second conductive element 23, and a third conductive element 24. The second conductive element 23 is located between the first conductive elements 22 and 23. All three conductive elements pass through the second component 12 and the magnetic core 13. In this embodiment, the upper ends of the first conductive elements 22, 23, and 24 are fixedly connected to the first component 11, and they are separated from each other. The lower ends of the first conductive elements 22, 23, and 24 pass through the magnetic core 13 and the second component 12, thus passing through the potting area. The adhesive 15 fills the gap between adjacent conductive elements, creating electrical isolation. Here, when the first conductive elements 22, 23, and 24 pass through the potting area, the gap between adjacent elements can be reduced, achieving a compact effect and reducing the overall volume, as long as the electrical isolation effect of the adhesive 15 is ensured. The second conductive element 23 extends downward through the isolator 14. The first connector 20 is connected to the first conductive element 22, extending from the side of the isolator 14 to the outside; this connection specifically refers to welding. The second connector 21 is connected to the third conductive element 24, extending from the side of the isolator 14 to the outside; this connection also specifically refers to welding. The three conductive elements form a three-phase circuit. The first connector 20, the second connector 21, and the isolator 14 cooperate to create isolation between circuits, preventing creepage.

[0049] Specifically, the first connector 20 extends from the left side of the isolator 14 to the outside and then bends vertically downwards, forming a parallel effect with the second conductive member 23; the second connector 21 extends from the right side of the isolator 14 to the outside and then bends vertically downwards, forming a parallel effect with the second conductive member 23. At this time, the lower ends of the first connector 20, the second connector 21, and the second conductive member 23 are arranged in parallel. The bottom surfaces of these three components can be flat and coplanar, or they can be at different heights; those skilled in the art can adjust this according to actual needs.

[0050] Specifically, the lower ends of the first conductive component 22, the second conductive component 23, and the third conductive component 24 are all riveted with press-fit nuts 29. The press-fit nuts 29 facilitate subsequent wiring.

[0051] Specifically, the first conductive element 22, the second conductive element 23, the third conductive element 24, and the first component 11 are integrally injection molded. This integral injection molding configuration makes processing more convenient and, secondly, increases the connection stability between the conductive elements and the first component 11.

[0052] Specifically, as shown in the attached document Figure 4 , Figure 6 As shown, the isolating member 14 has three isolation grooves 141, which are staggered and correspond to the first connector 20, the second connector 21, and the second conductive member 23, respectively. The isolation grooves 141 improve the isolation effect. The isolation groove 141 on the left has an opening on the left, the isolation groove 141 on the right has an opening on the right, and the middle isolation groove 141 runs vertically through the member. The left isolation groove 141 is located in the upper left region of the isolating member 14, and the right isolation groove 141 is located in the lower right region of the isolating member 14.

[0053] Specifically, as shown in the attached document Figure 3 As shown, one of the isolating member 14 and the second component 12 is provided with a fixing post 25, and the other of the isolating member 14 and the second component 12 is provided with a fixing hole 26 that mates with the fixing post 25. The mating of the fixing post 25 and the fixing hole 26 achieves the fixing effect between the isolating member 14 and the second component 12. Fasteners 28 can also be fitted onto the fixing post 25 to improve the stability of the fixation. When the isolating member 14 is provided with the fixing post 25, the second component 12 is provided with the fixing hole 26; conversely, when the isolating member 14 is provided with the fixing hole 26, the second component 12 is provided with the fixing post 25.

[0054] Specifically, the second component 12 is also fixed with a fixing nut 27, which is integrally molded with the second component 12. The fixing nut 27 is used to fix the entire copper busbar assembly to the fixing object. The integral molding design prevents the fixing nut 27 from falling off. The number of fixing nuts 27 and the position of the fixing nuts 27 in relation to the second component 12 can be adjusted according to actual needs.

[0055] Specifically, colloid 15 can be epoxy resin or rubber.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
