The utility model provides a multiple-to-one cable clip for extra-high-voltage direct-current large-diameter tube buses. The multiple-to-one cable clip comprises a chassis, two or above cable clip bodies, cable clip cover plates, and fasteners; one ends of the cable clip bodies are respectively connected with the same side of the chassis through the fasteners; and the other ends of the cable clip bodies are respectively provided with one cable clip cover plate; the cable clip cover plates are connected with the cable clip bodies through the fasteners; and the outer surfaces of the cable clip bodies and the cable clip cover plates are set into smooth surfaces. The multiple-to-one cable clip has the beneficial effects of carrying out the multiple-to-one connection of the extra-high-voltage direct-current large-diameter tube buses attractively, conveniently and easily and is corrosion resistant and less likely to generate the corona.
