Stacked conductive connecting device

The utility model discloses a stacking type conductive connecting device, which comprises a plurality of sheet-shaped connecting wires, an upper shell and a lower shell, one end of each sheet-shaped connecting wire is connected with a conductive contact assembly, and the other end of each sheet-shaped connecting wire is electrically connected with the conductive contact assembly, a connector joint, a power plug or a load. The conductive contact assembly comprises a first conductive contact piece and a second conductive contact piece which are embedded in the upper surface and the lower surface of a sheet-shaped connecting line. The upper end face of the lower shell extends to be provided with inserting columns used for abutting against the conductive contact assemblies, and the lower end face of the upper shell is provided with stacking grooves used for stacking the conductive contact assemblies. The sheet-shaped connecting line is reasonable in structural design, a plurality of sheet-shaped connecting lines
