  • Patent number: 7789688
    Abstract: The present invention provides a connector that has high contact reliability and versatility enabling the reliable electric connection of flexible printed boards with a spread in thickness and flexible printed boards with different thicknesses. In this connector, a wider portion of a connection terminal fixed to a base is lifted with a control lever in which rotatable shafts extending coaxially from end surfaces on both sides are rotatably supported on the base. In particular, bearing grooves extending in the vertical direction are provided at a pair of support clasps that are attached to respective end surfaces on both sides of the base. The rotary shafts of the control lever are mated with, and supported by, the bearing grooves rotatably and slidably in the vertical direction.
