The invention discloses a tension-strengthened type cable connector which comprises a connecting assembly and a wire clamping assembly. The wire clamping assembly is arranged outside a cable and fixedly connected with the cable. The connecting assembly is fixedly connected with the wire clamping assembly and comprises a front thread sleeve, a clamping ring, a first insulator and an outer shell. An annular groove is formed in the outer wall of the outer shell, an annular groove is formed in the inner wall of the front thread sleeve, and the outer shell is inserted into a center through hole of the front thread sleeve. The two ends of the clamping ring are embedded into the annular groove of the outer shell and the annular groove of the front thread sleeve respectively. The first insulator is arranged in a center through hole of the outer shell. The wire clamping assembly comprises a second insulator, an outer conductor and a cable clamp. The second insulator is arranged between the connection positions of an inner conductor of the cable and an insulator of the cable in a sleeved mode. The outer conductor is arranged on the outer circle of the insulator of the cable in a sleeved mode and leftwards extends to the position between the insulator of the cable and a shielding layer of the cable. The cable clamp is arranged outside the shielding layer of the cable in a sleeved mode and rightwards extends to a sheath of the cable. The tension-strengthened type cable connector is stable in electrical performance, firm in connection, large in tensile strength and good in product quality.
