The utility model discloses a super high tension power line cable connection structure, including left fixed plate and the right fixed plate that the symmetry set up, both ends are all fixed through the buffer about left fixed plate and the right fixed plate, and left fixed plate and the equal through fixed in right fixed plate middle part have the binding, the buffer is equipped with the sleeve,and the sleeve is pegged graft there is the footstalk, and there are first spring and second spring in footstalk grafting end bulge left and right sides butt respectively, and the sleeve is fixed in left fixed plate respectively with the footstalk and right fixed plate is inboard, the utility model discloses in the implementation process, the cable is bored a hole out by the second in at first penetrating first perforation again, and penetrating the third at last and boring a hole, under the stretched form, cable oppression butt piece, the fixed cable of clutch blocks butt is finally oppressedto inserted bar oppression wedge, and the cable pulling force is big more, and the degree that the butt was fixed is high more, when the pulling force is unusual, the flexible effect of playing the suppression buffering of first spring and second spring, not only have self -tightening solidus cable, it is unusual to restrain simultaneously the cable pulling force that the sinuous flow leads to.
