Among them, power distribution devices can be used to be responsible for the power distribution and management of high-voltage systems in electrical equipment. Power distribution devices can also be used in batteries to control the charging and discharging of batteries. The electrical components in the power distribution device usually have an electrical connection structure for electrical connection with other electrical components, but the electrical components in the power distribution device are compactly arranged, the spacing between the two electrical components is small, and the spacing between the electrical connection structures of the two electrical components is small, resulting in poor insulation between the electrical connection structures of the two electrical components, affecting the reliability of the power distribution device. Summary of the invention

[0108] The first electrical connection structure 111 and the second electrical connection structure 121 are spaced apart from each other. It is understandable that a gap is formed between the first electrical connection structure 111 and the second electrical connection structure 121 so that the first electrical connection structure 111 and the second electrical connection structure 121 do not contact each other, thereby reducing the risk of short circuit.

[0109] An insulating member 130 is provided between the first electrical connection structure 111 and the second electrical connection structure 121. It can be understood that the insulating member 130 is located between the first electrical connection structure 111 and the second electrical connection structure 121, that is, the insulating member 130 is located in the gap formed between the first electrical connection structure 111 and the second electrical connection structure 121. The insulating member 130 can insulate and separate the first electrical connection structure 111 and the second electrical connection structure 121 to improve the insulation between the first electrical connection structure 111 and the second electrical connection structure 121.

[0110] In the power distribution device 100 of the embodiment of the present application, in the first electrical device 110 and the second electrical device 120, an insulating member 130 is provided between the first electrical connection structure 111 of the first electrical device 110 and the second electrical connection structure 121 of the second electrical device 120.

[0112] When the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is the same at any position, the position at which the first electrical connection structure 111 and the second electrical connection structure 121 are at the shortest distance may refer to any position between the first electrical connection structure 111 and the second electrical connection structure 121; and when the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is different at different positions, the position at which the first electrical connection structure 111 and the second electrical connection structure 121 are at the shortest distance may refer to the position at which the spacing between the first electrical connection structure 111 and the second electrical connection structure 121 is the smallest.

[0113] By adopting the technical solution of this embodiment, the creepage distance of the first electrical connection structure 111 and the second electrical connection structure 121 is the smallest at the position with the shortest distance, that is, the insulation of the first electrical connection structure 111 and the second electrical connection structure 121 at the position with the shortest distance is poor, and the risk of short circuit is high. The insulating member 130 is arranged at the position with the shortest distance between the first electrical connection structure 111 and the second electrical connection structure 121, which can effectively improve the insulation at this position, thereby effectively reducing the risk of short circuit of the electrical connection structure of the two electrical devices, thereby effectively improving the reliability of the distribution device 100.

[0114] In another embodiment of the present application, Figure 7 As shown, the distance between the first electrical connection structure 111 and the second electrical connection structure 121 at the shortest distance is in the range of 3 mm to 9 mm.

[0115] The smaller the distance L between the first electrical connection structure 111 and the second electrical connection structure 121 at the shortest position, the more likely a short circuit will occur.

[0116] By adopting the technical solution of this embodiment, the spacing L at the shortest position between the first electrical connection structure 111 and the second electrical connection structure 121 is within 3mm to 9mm, which is prone to short circuit. The insulating member 130 is arranged at the shortest position between the first electrical connection structure 111 and the second electrical connection structure 121, which can effectively improve the insulation between the first electrical connection structure 111 and the second electrical connection structure 121, thereby effectively reducing the risk of short circuit.
