A novel cable connector comprises a main body, a clamp, a conductor assembly, and a controller. The main body is provided with an installation cavity and a receiving slot, and both sides of the receiving slot extend longitudinally to form a left and right wing. The clamp is arranged in the receiving slot, the receiving slot forming a passage for accommodating a cable. The conductor assembly is arranged on the installation cavity of the main body, and comprises a sharp lower end, which protrudes from the top surface of the receiving slot and is located in the passage. The clamp is located between the controller and the main body, the controller cooperates with the left wing and the right wing under an external force to directly apply a force to the clamp to drive the clamp to move towards the top surface of the receiving slot.
