Therefore, when the pinching force of the contact member is increased, the frictional force is also increased, making it difficult to insert and remove the connector. On the other hand, when the holding force of the contact member is reduced, the holding force of the connector after being fitted to the pin contact is reduced.

Pressure can be reduced. As a result, the socket contact can be connected to the pin contact while the insertion / extraction force is eliminated or greatly reduced. Further, after the joining of the socket contact and the pin contact, by releasing the operation of the operation movable member, the two contact terminals can pinch the pin contact and maintain a stable holding state.
