When an element is referred to as "arranged on" another element, it can be arranged on the other element or there can be a centered element.

[0033] Reference Figure 1 and Figure 2, an embodiment of the present application provides a busbar assembly 100, specifically, the busbar assembly 100 includes a first busbar 10, a second busbar 20, an insulating support seat 30 and an insulating plastic sealing member 40. Exemplarily, at least one of the first busbar 10 and the second busbar 20 can be a copper busbar or an aluminum busbar. The first busbar 10 includes a first end 110 and a second end 120 arranged opposite to each other, and the second busbar 20 includes a third end 210 and a fourth end 220 arranged opposite to each other. The insulating support seat 30 abuts between the first busbar 10 and the second busbar 20, so as to ensure the safety distance between the upper and lower busbars, and further ensure that the creepage distance and electrical clearance between the upper and lower busbars are qualified. The insulating plastic sealing member 40 covers the area of ​​the first busbar 10 except the first end 110 and the second end 120, and also covers the area of ​​the second busbar 20 except the third end 210 and the fourth end 220, and also covers the insulating support seat 30. Exemplarily, the insulating plastic package 40 can be obtained by injection molding. Specifically, the stacked first busbar 10, the second busbar 20 and the insulating support seat 30 can be placed in an injection mold cavity for integral injection molding to obtain the busbar assembly 100. Exemplarily, the material of the insulating plastic package 40 can be polyphenylene sulfide (PPS), polyphthalamide (PPA) or a flame retardant epoxy resin.

[0034] In the present application, an insulating support seat 30 is additionally provided between the first busbar 10 and the second busbar 20 to ensure the safety distance between the busbars in advance, thereby helping to reduce the risk of insulation failure of the busbar assembly 100.

[0035] In some embodiments, referring to Figure 2 and Figure 3 , the insulating support seat 30 is provided with a first groove 31, the first busbar 10 is clamped in the first groove 31, and the first end 110 and the second end 120 both extend out of the first groove 31. Exemplarily, the number of the first busbars 10 can be one or more. When the number of the first busbars 10 is multiple, exemplarily, the multiple first busbars 10 can be arranged flat and abut against each other, so that the multiple first busbars 10 can be clamped in the first groove 31. The first groove 31 is conducive to assisting the positioning of the first busbar 10, thereby helping to reduce the number of positioning parts in the mold cavity when the busbar assembly 100 is formed, simplifying the design difficulty of the mold, and thus helping to improve the service life of the mold. In addition, after the first groove 31 positions the first busbar 10, it is not necessary to use additional positioning parts to stabilize the first busbar 10, thereby reducing the probability of penetrating the insulating plastic sealing part 40 to expose the first busbar 10, and further reducing the risk of insulation failure of the busbar assembly 100.

[0036] In some embodiments, the insulating support seat 30 is further provided with a second groove 32, which is arranged away from the first groove 31 and the two are separated, that is, the top openings of the two grooves face opposite directions, and the second busbar 20 is clamped in the second groove 32, and the third end 210 and the fourth end 220 both extend out of the second groove 32. Exemplarily, the number of the second busbars 20 can also be one or more, and similarly, the second groove 32 positioning the second busbar 20 is also conducive to further reducing the risk of insulation failure of the busbar assembly 100.

[0037] In some embodiments, reference Figures 1 to 3 , the first groove 31 has a first side opening 310. The first busbar 10 includes a first row portion 11 and a second row portion 12. Exemplarily, the first row portion 11 and the second row portion 12 can be integrally formed. The first row portion 11 includes a first end 110, which is clamped in the first groove 31, and the first end 110 extends out of the first side opening 310. The second row portion 12 includes a second end 120, and the second row portion 12 is convexly disposed on the first row portion 11 away from the second groove 32, and the second row portion 12 abuts against the side wall of the first groove 31 relative to the first side opening 310. The first side opening 310 facilitates the quick insertion of the first busbar 10. In addition, the orientation of the second row portion 12 is conducive to increasing the safety distance between the second end 120 and the second busbar 20.

[0038] In some embodiments, the second groove 32 has a second side opening 320, and the second side opening 320 is arranged away from the first side opening 310, that is, the two openings are in opposite directions. The second busbar 20 includes a third row portion 21 and a fourth row portion 22. Exemplarily, the third row portion 21 and the fourth row portion 22 can be integrally formed, and the third row portion 21 includes a third end 210, and the third row portion 21 is clamped in the second groove 32, and the third end 210 extends out of the second side opening 320. The fourth row portion 22 includes a fourth end 220, and the fourth row portion 22 is convexly arranged on the third row portion 21 away from the first groove 31. The arrangement of the second busbar 20 is conducive to improving the compactness of the busbar assembly 100. In addition, the structure of the second busbar 20 is also conducive to increasing the safety distance between the fourth end 220 and the first busbar 10.

[0039] In some embodiments, the first row portion 11 and the second row portion 12 are connected by an arc transition, which helps to improve the service strength of the first busbar 10 and prevent stress cracking caused by sharp angles, thereby helping to increase the service life of the busbar assembly 100.

[0040] In some embodiments, the third row portion 21 and the fourth row portion 22 are connected by an arc transition, which helps to improve the service strength of the second busbar 20 and prevent stress cracking caused by sharp angles, thereby helping to increase the service life of the busbar assembly 100.

[0041] In some embodiments, the insulating support seat 30 is a plastic part. For example, the material of the insulating support seat 30 can be polyphenylene sulfide (PPS), polyphthalamide (PPA) or a flame retardant epoxy resin. The insulating support seat 30 is made of a plastic part, which is convenient for molding and helps to reduce weight. For example, the insulating support seat 30 can be prepared by injection molding or extrusion molding.

[0042] In another embodiment, the material of the insulating support seat 30 may be rubber or glass.

[0043] In some embodiments, the cross section of the first busbar 10 is square when viewed along the arrangement direction of the first end 110 and the second end 120, and the cross section of the second busbar 20 is square when viewed along the arrangement direction of the third end 210 and the fourth end 220. When the cross-sectional area is the same, the perimeter of the square cross section is relatively large, which is conducive to improving heat dissipation. In addition, the square cross section is conducive to reducing the skin effect, and the square cross section is also conducive to reducing the package volume.

[0044] In another embodiment, the cross-sections of the first busbar 10 and the second busbar 20 may be circular or groove-shaped.

[0045] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
