Coaxial connector

The utility model discloses a coaxial connector for connecting a coaxial cable, comprising an insulating sleeve, a coupling member and a conductive terminal. The coupling member is of a tubular conductive structure, the insulating sleeve is positioned in the coupling member, and the back end of the coupling member is provided with an internal connecting surface. The back end of the conductive terminal is provided with a location notch for welding component wires of the coaxial cable. The conductive layer of the coaxial cable is penetrated and arranged in the back end of the coupling member and is adjacent to the internal connecting surface, and the conductive layer is welded to the coupling member. Thus, the connection of the coaxial cable is simple, and the location is accuracy. The favorable electrical specification can be maintained without unfolding the conductive layer. The utility model has the advantages of broad applicability, wide applicable frequency range, high stability and small loss of the signal.
