Electric Connector

An electric connector with a socket connector and a plug connector having a bar shape for connecting an electric circuit, the plug connector being arranged to be capable of being inserted to and removed from the socket connector and to be rotatable between an unlocked position and a locked position about an axis thereof, the electric connector comprising:

• a pair of detection terminals opposing across the plug connector;
• and
• a conductive member for providing electric conduction between the pair of detection terminals in the locked position of the plug connector, the conductive member including:
• a pair of pressed pieces arranged between the pair of detection terminals and the plug connector, the pair of pressed pieces being spaced away from the detection terminals in the unlocked position of the plug connector, but being pressed by an outer surface of the plug connector in the locked position of the plug connector to bring contact portions thereof into contact with the detection terminals;
• and
• a coupling piece connecting the pair of pressed pieces.
