ELECTRIC CONNECTOR

PROBLEM TO BE SOLVED: To prevent detachment of a cam part when an actuator is at an opening position with a simple constitution.SOLUTION: A cam engagement face 12a2 that is a plane opposed to a cam locking protrusion 13a of a second contact beam 13a when an actuator 12 is at an opening position is provided to a cam part 12a of the actuator 12 swinging a contact 13 mounted in an insulation housing 11. Even if an external force and the like for detaching the cam part 12a from a cam rotation recess 13b3 is applied when the actuator 12 is at the opening position, the cam engagement face 12a2 of the cam part 12a comes into contact with the cam locking protrusion 13a2 into a locking condition, so as to prevent detachment of the actuator 12.
