Dans la première position de fonctionnement, le FPC/ FFC est inséré dans le logement ou extrait de celui-ci et dans la seconde position de fonctionnement, le FPC/ FFC est fixé dans le logement. Ledit connecteur comprend également une structure de blocage formée sur l'actionneur et les parties arrières des terminaux en métal, qui est destinée à fixer le aux terminaux en métal, lorsque l'actionneur est dans la seconde position de fonctionnement. Selon l'invention, l'actionneur du connecteur de câble flexible destiné à fixer un FPC/ FFC est fortement fermé et fixé, ce qui évite d'endommager le FPC/ FFC lors de l'ouverture de l'actionneur. De plus, le connecteur de câble flexible de l'invention peut améliorer la stabilité de travail et la possibilité de percevoir la fin du travail.
