And a fitting nail 40 which is raised for insertion in 20a.

In this case, a seating slot 11 is formed at the front end of the housing 10 to fix the FPC / FFC, and a terminal insertion part 12 into which the terminal 20 is inserted is fixed at the rear end of the housing 10. Fixed arms 13 are formed at both sides of the housing 10, and fixing grooves 13a are formed at both ends of the actuator 30 inside the fixed arms 13.

In addition, both sides of the rear end of the actuator 30 protrude from the fixing protrusion 31 rotatably fixed to the fixing groove 13a formed inside the fixing arm 13, and the actuator 30 is provided at both ends of the front end of the actuator 30. The locking protrusion 32 is formed to protrude from both sides of the front portion of the housing 10 to lock the actuator 30 so as not to rotate when the 30 is positioned in the closed position.

On the other hand, the rear end of the actuator 30 is formed with a rotating shaft 33 is inserted into the pivot groove 20a of the terminal 20 to form the center of rotation of the actuator 30.
