The utility model belongs to the field of electrotechnical products and relates to a self-supporting waterproof type signal shielding cable which comprises at least two conductors; the conductors are coated with insulation layers to form insulation wire cores; the insulation wire cores form a cable core in a pair twisting manner; filler yarn is arranged between the insulation wire cores in the cable core; an overlapped winding packaged polyester tape is arranged at the periphery of the cable core; a metal shielding layer is arranged outside the polyester tape; a water-resisting tape is arranged outside the metal shielding layer; an outer protecting layer is arranged outside the water-resisting tape in a tightly coated manner; and a steel wire rope is coated on the outer side of the outer protecting layer in parallel. Under the premise that the signal transmission performance of an ordinary signal shielding cable is kept unchanged, the self-supporting waterproof type signal shielding cable has the functions of
