The invention provides an improved audio cable connector, which comprises a connector body, a mounting bracket, anti-breaking reinforcement bodies, a driving sleeve, locking assemblies and a clampingframe assembly, wherein the top end of the connector body is provided with an audio plug, the mounting bracket is installed on the head end of the connector body by means of a plurality of bolts, theanti-breaking reinforcement bodies are installed on the tail end of the connector body by means of a plurality of bolts, one end of each locking assembly is fixed on a telescopic bracket, the other end of each locking assembly is provided with a locking block, clamping plates matched with the locking blocks are symmetrically arranged on the clamping frame assembly, an installation connecting bodyis arranged on the anti-breaking reinforcement bodies, the driving sleeve is in threaded connection with the installation connecting body, and the driving sleeve drives the anti-breaking reinforcementbodies to shrink in the radial direction so as to clamp an audio cable tightly. Through installing an anti-rotation body and the locking assemblies on the connector body, the accidental drop-off problem caused by rotation of the connector in the using process can be effectively prevented, the firmness of connection is enhanced, breakage of the cable joint is avoided through clamping the audio cable by means of the anti-breaking reinforcement bodies, and the service life of the audio cable is prolonged.
