The invention discloses a wedge-shaped connector device used for an elevator dragging suspension cable. The wedge-shaped connector device comprises a wedge-shaped sleeve and a wedge block matched with the wedge-shaped sleeve, and a penetrating channel for the suspension cable is formed between the matching faces of the wedge-shaped sleeve and the wedge block. At least two steel wire ropes are sequentially arrayed inside the suspension cable, a suspension cable penetrating groove formed in the direction of the penetrating channel is formed in the matching face of the wedge-shaped sleeve or the wedge block and provided with an arc-shaped section, and the arc height is smaller than or equal to the radius of the steel wire ropes inside the suspension cable. The number of the suspension cable penetrating groove is one, and the suspension cable penetrating groove is throughout the matching face, where the suspension cable penetrating groove is formed, in the arc length direction. The chord length of the suspension cable penetrating groove is larger than or equal to the sum of the diameters of all the steel wire ropes inside the suspension cable. The wedge-shaped connector device is adapted to an elevator system adopting the flat-belt-shaped flexible dragging suspension cable, stress elements inside the dragging suspension cable will not disengage from the wedge-shaped connector device when the wedge-shaped connector device is used in a high-temperature environment, and using safety of the elevator system is improved.
