Coaxial connector

The utility model discloses a coaxial connector which matches with an abutting connector. The inner annular surface of the inserting end of the abutting connector is provided with an inner concave groove which is provided with an axial plane groove bottom. The coaxial connector comprises a body whose front end is provided with a springing mechanism; the free end of the springing mechanism is provided with an outward flange which is provided with an axial outer annular plane. When the springing mechanism is inserted into the insertion space of the abutting connector, the outward flange is embedded in the inner concave groove, and the axial outer annular plane of the outward flange contacts the axial plane groove bottom of the inner concave groove on the surface. In this way, the coaxial connector of the utility model is stably abutted with the abutting connector, and twisting fore is added to ensure the definition of receiving signals and the quality of transmission signals.
