Further, a part 407 of the external conductor 401 is exposed from the housing 403.

When fitting the receptacle connector 400 and the plug connector 1, it is sufficient to press the plug connector 1 from above. Since the locking member 404 has elasticity and the locking portion 406 has an inclined surface on the upper side, the locking member 404 can be opened to the left and right to easily fit. Further, after the fitting is completed, the lower side of the locking portion 406 is substantially perpendicular, so that the locking portion 406 is engaged with the ceiling surface 11 of the plug connector 1 and is completely locked.

When removing the plug connector 1, as shown in FIG. 23, by using the jig 408, it can be removed by increasing the space between the lock members 404.

Therefore, the receptacle connectors 100, 200, 300, and 400 of the first to fourth embodiments are provided with the locking members 104, 204, 304, 404, respectively, so when fitting with the plug connector 1, The reliability of the electric connector is improved because the locking member can completely lock by pressing the plug connector to maintain the fitting state.

As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment, but it is needless to say that the invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the invention. Moreover, you may suitably combine each of said Embodiments 1-4.

The present invention can be used for a coaxial connector requiring high reliability.
