Most of the existing contact type charging connection modes are realized by matching a charging pin (pin) with an elastic sheet. When the pin needle is in interference fit with the elastic piece in the assembling in place, the elastic piece generates elastic deformation to ensure effective contact with the pin needle, and the conductive function is realized. Because the elastic sheet is of a plane structure, the pin needle and the elastic sheet are in point contact, and poor contact can be caused when the elastic sheet or the surface of the pin needle is partially oxidized; when dust accumulates on the elastic sheet, poor contact can also be caused, so that the electric conduction cannot be effectively carried out, and the electric conduction effect is influenced.
