As described in the above embodiments, according to the connector device of the present invention, the contact portion of the contact only rotates around the axis of the fitting shaft, and the position before and after the contact is changed. Since the rod-like portion following the contact portion does not move and is inserted into the housing to the extent that it can rotate, the contact portion does not fluctuate and moves, and positioning of the contact with respect to the housing becomes easy.

Further, even when the length of the contact in the axial direction is long, the contact is mounted in such a combination that it can be twisted and turned so that the rod-shaped portion is almost in close contact with the housing. There is no danger that the contacts will be deformed even in handling.

The contact between the contact and the contact portion includes
Leverage leverage, that is, leverage structure that applies the leverage principle, uses only a small amount of external driving force for contact, and is fully applicable to connectors with multi-core contacts. Becomes possible.

Further, since there is no relative movement between the housing and the movable plate provided with the contacts and the mating connector, it can be applied in the field of a connector device in which such a mating connector is mounted.
