[0026] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0027] Embodiment one, as shown in Figure 1 and Figure 2 and Figure 3 A battery conductive connection structure, including a positive pole 1, a negative pole 2, a positive conductive plate 3 and a negative conductive plate 4, a battery 5 is arranged in a box 6, the positive pole 1 is electrically connected with the positive conductive plate 3, the negative pole 2 is electrically connected with the negative conductive plate 4, the positive conductive plate 3 is used for connecting the positive pole of the battery 5, the negative conductive plate 4 is used for connecting the negative pole of the battery 5, and the positive conductive plate 3 and the negative conductive plate 4 are overlapped on the box 6.

[0028] The first through hole 30 is arranged on the positive conductive plate 3, the second through hole 40 is arranged on the negative conductive plate 4, the lower end of the positive pole 1 is fixedly connected in the first through hole 30, and the lower end of the negative pole 2 is fixedly connected in the second through hole 40. In this way, after the positive pole 1 and the negative pole 2 are electrically connected with the load, the load is not easy to separate from the positive pole 1 and the negative pole 2, the positive pole 1 is not easy to separate from the positive conductive plate 3, and the negative pole 2 is not easy to separate from the negative conductive plate 4.

[0029] The positive conductive plate 3 and the negative conductive plate 4 are both metal plates, and the positive conductive plate 3 and the negative conductive plate 4 have large cross-sectional areas, so the positive conductive plate 3 and the negative conductive plate 4 have strong conductivity.

[0030] The positive conductive plate 3 and the negative conductive plate 4 are both bent and arranged, and the positive conductive plate 3 and the negative conductive plate 4 are bent and arranged to match the shape of the box 6.

[0031] The positive pole 1 is welded at the lower end in the first through hole 30, and the negative pole 2 is welded at the lower end in the second through hole 40, so that the positive pole 1 and the positive conductive plate 3 are fixedly connected together, and the negative pole 2 and the negative conductive plate 4 are connected together.

[0032] The positive pole 1 has a first positioning column 10, and at least one first positioning face 11 is arranged on the first positioning column 10, and the first positioning column 10 is fixedly connected in the first through hole 30, and the negative pole 2 has a second positioning column 20, and at least one second positioning face 21 is arranged on the second positioning column 20, and the second positioning column 20 is fixedly connected in the second through hole 40.

[0033] At least one first reference face 31 is arranged in the first through hole 30, and at least one second reference face 41 is arranged in the second through hole 40, the first reference face 31 is used to match the first positioning face 11, so that the first positioning column 10 can be prevented from rotating in the first through hole 30, and the second reference face 41 is used to match the second positioning face 21, so that the second positioning column 20 can be prevented from rotating in the second through hole 40, when the first positioning column 10 is to be sleeved in the first through hole 30, the first positioning face 11 needs to be attached to the first reference face 31, so that the first positioning column 10 can enter the first through hole 30, and when the second positioning column 20 is to be sleeved in the second through hole 40, the second positioning face 21 needs to be attached to the second reference face 41, so that the second positioning column 20 can enter the second through hole 40.

[0034] The first through hole 30 and the second through hole 40 are waist-shaped holes in this example, and can also be rectangular holes.

[0035] A plurality of first vertical strips 12 are arranged on the outer periphery of the positive pole 1, and a plurality of second vertical strips 22 are arranged on the outer periphery of the negative pole 2, and the positive pole 1 and the negative pole 2 are both aluminum products, so the first vertical strips 12 and the second vertical strips 22 are also aluminum strips, the plurality of first vertical strips 12 are arranged around the positive pole 1, the plurality of second vertical strips 22 are arranged around the negative pole 2, the plurality of first vertical strips 12 are uniformly arranged around the outer periphery of the positive pole 1, and the plurality of second vertical strips 22 are uniformly arranged around the outer periphery of the negative pole 2.

[0036] Therefore, the first positioning column 10 and the second positioning column 20 are both aluminum products, which is conducive to the interference fit of the first positioning column 10 with the first through hole 30 and the interference fit of the second positioning column 20 with the second through hole 40, and the first vertical strips 12 and the second vertical strips 22 can increase the friction when the positive pole 1 and the negative pole 2 are manually operated, which is conducive to rotating the positive pole 1 and the negative pole 2.

[0037] In Example 2, the lower end of the positive terminal 1 is riveted into the first through hole 30, and the lower end of the negative terminal 2 is riveted into the second through hole 40. Riveting has a strong load-bearing capacity. Compared with welding, riveting is more suitable for connecting large and heavy-duty components. The rivet has a stronger load-bearing capacity and can maintain its stability even in high-temperature environments. Riveting is easy to operate and has a low cost.

[0038] In Example 3, the positive electrode post 1 is fixed in the first through hole 30 by welding and riveting, and the lower end of the negative electrode post 2 is fixed in the second through hole 40 by welding and riveting.

[0039] like Figure 4 As shown, the outer periphery of the positive electrode post 1 and the positive conductive plate 3 is welded to form a welded part 7, and the outer periphery of the negative electrode post 2 and the negative conductive plate 4 is welded to form a connecting part 7. The welded parts 7 at both locations are wrapped around one circle. The fixing method of riveting and welding is more secure than welding or riveting alone.
