Abstract
The utility model relates to a wire fixing device for coaxial connectors. A metal shell is arranged by drawing out and a hollow tube-shaped part is arranged on the shell. An outer covering body is arranged at one end of the tube-shaped part and a curved lower covering part is arranged at the other end. The area of the outer covering body is larger than that of the tube-shaped part and a wing part stretching outward is respectively arranged at the two sides of the outer covering body. An upper covering part is positioned at the other end of the outer covering body corresponding to the tube-shaped part. The area of the upper covering part is larger than that of the lower covering part, therefore when an insulator is arranged in the tube-shaped part and a cable with a terminal is arranged on the lower covering part, the outer covering body can be bended to cover the tube-shaped part and meanwhile, the upper covering part covers the cable, bends the wing part of the outer covering body and extrudes the upper covering part downward so as to fix the outer covering body on the tube-shaped part and the upper covering part on the lower covering part. In this way, as the cable is tightly covered by the upper and lower covering parts, the cable can not depart from the upper covering part or cause any fracture when the connector is drawn out.
