furthermore, threads are arranged in the tail part of the cable clamp, and can increase the friction force between the cable clamp and a cable sheath and prevent the cable from falling off in the installation process;

preferably, the inner diameter of the outer conductor compression screw sleeve is matched with the outer diameter of the head part of the cable clamp, and the inner diameter of the outer sheath clamping nut is matched with the outer diameter of the tail part of the cable clamp;

preferably, the upper edge of the outer sheath clamping nut is a circular ring with two opposite sides cut off in an arc shape respectively, and the circular ring is matched with the outer sleeve of the high-voltage cable connector.

The utility model has the advantages that:

(1) elasticity lock screwed structure, use oversheath clamping nut, the outer conductor compresses tightly that the swivel nut and cable clamp can be convenient locks high tension cable, and is easy and simple to handle swift.

(2) Elasticity lock screw up structure, the cable clamp comprises the sheetmetal, utilizes gap and the good ductility of metal material between the sheetmetal, can make things convenient for its crimple and expansion, can adapt to the high tension cable of different specifications, it is also more convenient at the in-process that uses, easy operation.
