Heavy-current straight-through type connector capable of repeatedly pulling covers at two ends

The utility model relates to a heavy-current straight-through type connector capable of repeatedly pulling covers at two ends. The connector comprises an insulating main shell, a U-shaped hardware conductive piece, a wire pressing copper sheet, two insulating end shells and two insulating pulling covers, a first rectangular cavity penetrating through the two corresponding ends of the insulating main shell is formed in the insulating main shell, the U-shaped hardware conductive part is laterally fixed in the first rectangular cavity, the middle of the wire pressing copper sheet is flatly fixed to the inner bottom face of the U-shaped hardware conductive part, and the two ends of the wire pressing copper sheet are elastically pressed to the inner top face of the U-shaped hardware conductive part in a spaced mode. The two insulating end shells are respectively butted and fixed at two ends of the insulating main shell, and the two insulating shifting covers are respectively arranged at the tops of the insulating
