One end, in contact with a conductor, of the contact finger seat is equipped with a contact finger frame (5). The contact finger frame (5) is a truncated cone-shaped shell body composed of an inner shell (5a) and an outer shell (5b). The circumferential surface of the outer shell of the contact finger frame is provided with a plurality of uniformly-distributed grooves (5c) along the axial direction. A plurality of elastic contact fingers (4) are clamped in each groove. The top ends of the elastic contact fingers are hook-shaped and are hooked to the top end face of the inner shell. The contact ends of the elastic contact fingers extend out of the grooves, the inner sides of the contact ends are pressed against the contact finger seat, and the outer surfaces of the contact ends are higher than the outer surface of the outer shell. The electrical connecting device of the utility model is applicable to long-distance high-voltage power transmission, and is especially matched with an external plug-in structure of a large-diameter and thick-wall aluminum pipe profile conductor. The groove structure on the contact finger frame can satisfy the requirement of large radial deformation of the conductor. A shielding cover structure ensures the uniformity of an internal electric field of a GIS air chamber.
