A connector (20) for a coaxial cable (10). The cable comprises an outer conductor (11), an inner conductor (12) and an insulating medium (13) located between the outer and the inner conductors, wherein the connector comprises a connector front body (21) and a connector rear body (22) inserted therein; the connector front body comprises a hollow shell (30); the connector rear body comprises a flare ring (50), a slot finger and a lock nut (70) which are inserted into the shell, wherein the flare ring at one end thereof rests against a shoulder (37) in the shell, the slot finger is mounted on the flare ring, and the lock nut is mounted on the slot finger and engages the inner surface of the shell; the flare ring is provided with adjacent the first incline (54) and the first plane (55), and the slot finger is provided with adjacent the second incline (67) and the second plane (66), wherein the first incline is used for insertion between the outer conductor and the insulating medium of the coaxial cable, and the first incline and the first plane respectively cooperate with the second incline and the second plane, so as to simultaneously flare and crush the outer conductor of the coaxial cable. The cable connector can gain excellent third order intermodulation performance and high frequency transmission performance.
