Abstract
Disclosed in the utility model is a quick connector for a coaxial cable. An inner flange is arranged at a right end of a connecting nut; an outer flange is arranged at a left end of a bush core tube; a sealing ring is arranged between the outer flange of the bush core tube and the inner flange of the connecting nut; and a core-shaped inverted drawing portion is arranged at an outer wall of the right end of the bush core tube. A core conductor is arranged in the middle of the coaxial cable; and the periphery of the core conductor is successively coated by an insulated layer, a metal foil layer, a metal braiding stranded wire layer and a cable outer sheath. A left end of an outer sleeve tube is sleeved in the middle of the bush core tube; the core conductor, the insulated layer and the metal foil layer of the coaxial cable are inserted into the bush core tube together from the right end; the core conductor extends out of the center of the connecting nut; and the metal braiding stranded wire layer and the cable outer sheath of the coaxial cable are arranged outside the bush core tube. A left end of a tail inwardly-inserted locking element is inserted into the inner wall of the right end of the outer sleeve tube; and the inner wall of the tail inwardly-inserted locking element compresses the cable outer sheath at the bush core tube. The provided quick connector has the good sealing performance and can support the great torsion force and the tensile force.
