Power line assembly

The embodiment of the utility model provides a power line assembly. The power line assembly comprises a wire box and a power line used for transmitting electric energy. The wire box has an accommodating space. The wire box is provided with a first connecting part and a second connecting part. The power line comprises a line body, and a third connecting part and a fourth connecting part which are sequentially arranged on the line body in the first direction. A part of the wire body is arranged in the accommodating space. And the third connecting part is matched with the first connecting part, and the fourth connecting part is matched with the second connecting part, so that the power line and the line box are positioned. According to the wire box, the power line and the wire box are subjected to multiple positioning through the first connecting part and the second connecting part, the reliability of a connecting structure between the power line and the wire box is improved, when a user drags the power line, the connecting structure between the power line and the wire box can be prevented from being damaged to a certain degree, and the user experience is improved. Therefore, the problem of unreliable grounding caused by stress of the grounding wire is solved, the problem of potential safety hazards such as electric shock of a user is reduced, and the safety performance is improved.
