  • Patent number: 8408928
    Abstract: A connector is used to transmit a signal from a flexible board to an external device. The connector includes an actuator, a supporter, contact terminals, and an outer cover. The actuator includes a body having a slit opened to a front surface and extended in a longitudinal direction of the slit, and a pivot positioned at opposing longitudinal ends of the body. The slit receives the flexible board inserted from the front surface direction. The actuator is rotated with reference to the pivot. The supporter extends in the longitudinal direction and is adjacent to the front surface of the actuator. The contact terminals extend through the supporter and the body, and protrude into the slit. The actuator receives the flexible board when at a first position, and each contact terminal makes contact with the flexible board when the actuator is at a second position different from the first position.
