The Patent Description & Claims data below is from USPTO Patent Application 20060223350, Connector having a rotary engaging member.

1. A connector for connecting a connection object having a locked portion, the connector comprising: a movable member movable in a predetermined direction between a connecting position and an ejecting position together with the connection object; a cam mechanism couple to the movable member for selectively maintaining the movable member at the connecting position or at the ejecting position; a first engaging member held by the movable member and rotatable in a rotating direction, the first engaging member having a locking portion to be engaged with the locked portion in the predetermined direction when the first engaging member is located at a predetermined angular position; and a braking device coupled with the first engaging member to brake the first engaging member in the rotating direction.

2. The connector according to claim 1, wherein the braking device has a braking force controlled so that the braking force is small when the movable member is at the ejecting position as compared with that when the movable member is at the connecting position.

3. The connector according to claim 1, wherein the braking device comprises: a second engaging member mounted to the movable member to be movable in the predetermined direction and faced to the first engaging member in the predetermined direction; and an elastic member continuously urging the second engaging member towards the first engaging member in the predetermined direction, the first engaging member further having a cam surface for pressing the second engaging member against the elastic member during rotation.

4. The connector according to claim 3, wherein the locking portion and the cam surface have phases selected so that, when the connection object moves from the connecting position to the ejecting position, the locking portion is pressed by the locked portion to rotate the first engaging member and the cam surface presses the second engaging member.

5. The connector according to claim 3, wherein the first engaging member is rotatable with respect to a rotation shaft perpendicular to the predetermined direction.

6. The connector according to claim 3, further comprising a housing holding the movable member and the cam mechanism, the elastic member being interposed between the housing and the second engaging member.

7. The connector according to claim 3, wherein the second engaging member comprises: a flange portion faced to the first engaging member; and a rod-like portion extending from the flange portion in the predetermined direction, the elastic member comprising a coil spring fitted over the rod-like portion and having one end engaged with the flange portion.

8. The connector according to claim 7, wherein the second engaging member further has a spindle portion extending from the rod-like portion in the predetermined direction inside the coil spring.

9. The connector according to claim 1, further comprising: a housing holding the movable portion and the cam mechanism; a conductive contact held by the housing and adapted to be contacted with the connection object at the connecting position; and a cover frame coupled with the housing and defining the connecting position in cooperation with the housing.

10. A connector to be connected to a connection object having a locked portion, the connector comprising: a movable member to be contacted with the connection object and movable together with the connection object; a cam mechanism for selectively maintaining the movable member at a connecting position or an ejecting position of the connection object; and an elastic member for continuously urging the connection object towards the ejecting position. the movable member having an engaging member provided with a locking portion to be engaged with the locked portion, the engaging member being rotatably held by a rotation shaft and adapted to lock a connected state of the connection object, the elastic member continuously urging the locking portion towards the locked portion.

11. A connector comprising a housing and an ejecting mechanism formed on the housing to connect a connection object having a locked portion at a connecting position and to eject the connection object to an ejecting position, wherein the ejecting mechanism comprises: an ejecting member to be contacted with the connection object and movable together with the connection object, the ejecting member having an engaging member provided with a locking portion to be engaged with the locked portion; a cam mechanism for selectively maintaining the ejecting member at the connecting position or the ejecting position of the connection object; and an elastic member urging the engaging member towards the ejecting position, the engaging member being rotatably held by a rotation shaft formed on the ejecting member and being adapted to lock a fitted state of the connection object, the elastic member urging the locking portion towards the locked portion.

12. The connector according to claim 11, wherein the engaging member comprises: a first engaging member; and a second engaging member continuously urged by the elastic member, the first engaging member comprising: the locking portion to be inserted into the locked portion to be engaged therewith; and a first contacting portion for receiving a load of the elastic member.

13. The connector according to claim 12, wherein the second engaging member has a second contacting portion contacted with the first contacting portion.
