Electrical connector with locking engagement between an actuator and an insulative housing

An electrical connector for connecting a flexible printed circuit board comprising:

• an insulator comprising a top wall, a bottom wall opposite to the top wall and a pair of side wall joining with the top wall and the bottom wall thereby defining a cavity therebetween;
• a plurality of terminals arranged exposed into the cavity;
• and
• an actuator mounting onto the insulator and rotated between an opened position where the flexible printed circuit board can be inserted into the cavity and a closed position where the flexible printed circuit board can be depressed downward to abut against the terminals;
• wherein a post protrudes from the bottom wall, the actuator defines a locking beam for locking with the post and a through hole for receiving the post when the actuator is located at the closed position.

An electrical connector assembly comprising:

• an insulative housing defining a cavity;
• a plurality of contacts disposed in the housing with contacting sections exposed in the cavity;
• a flexible printed circuit (FPC) defining a contact end received in the cavity and mechanically and electrically connecting to the contacts, said FPC further defining at least one through hole;
• and
• an actuator pivotally mounted to the housing and covering the cavity to cooperate with the housing to sandwich the FPC therebetween;
• wherein
• at least one of the housing and the actuator defines a post extending through the through hole toward the other, and an interlocking mechanism located proximate said post and said through hole fastens the actuator to the housing.
