Even if the amount is small, it serves to securely lock.

[0031]

As described in the above embodiments, according to the coaxial connector device of the present invention, the connector is moved to the mating connector, and the first projection is formed in the groove of the mating connector. By merely moving to the first regulating position so as to engage, the coupling can be securely fitted to the mating connector by moving the coupling in the second direction by the spring force.

At the time of fitting, the first projection is engaged with the groove of the mating connector, the first projection is pressed by the second projection, and the second projection is pressed by the coupling nut. The displacement of the projection is restricted, so that the fitting is not disengaged even if the cable connected to the connector is pulled in the second direction.

Further, when the coaxial connector is separated from the mating connector, the coupling nut is moved in the second direction B.
When moved to, there is a space above the first spring portion and the second spring portion , so that the first spring portion and the second spring portion can be displaced, and only the coupling nut is gripped and pulled. Can be separated by the force of
