This directional definition is merely for convenience of description and to facilitate understanding of the structures of the utility model by those skilled in the art, and is not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, a cable connector according to an embodiment of the present utility model includes a contact tube 1 and a protective tube 4 assembled by using a left tube 41 and a right tube 42 as main components. Two clamping positions 11 are arranged on the conductive copper pipe 1. The two ends of the conductive copper pipe 1 are symmetrically provided with a left tightening clamp ring 2 and a right tightening clamp ring 3 in a round table shape. The two ends of the conductive copper pipe 1 are respectively abutted against the big head ends of the left tight clamping ring 2 and the right tight clamping ring 3. The left cylinder 41 and the right cylinder 42 are respectively sleeved on the left tight clamping ring 2 and the right tight clamping ring 3 to ensure that the left tight clamping ring 2 and the right tight clamping ring 3 clamp the cable. The left tightening clamping ring 2 and the right tightening clamping ring 3 are respectively provided with a cutting groove 5 for compensating deformation along the axial direction.
