Abstract:
1. A flat cable electrical connector, comprising: a housing; a plurality of terminals made of sheet metal and arranged in said housing at predetermined intervals in a first direction perpendicular to said sheet metal; and a movable member rotatable between an open position and a closed position and having a cam portion, each of said terminals including a contact projection, a lever arm extending in a second direction in which a flat cable is inserted into said electrical connector and having a fulcrum at a middle point thereof, and an attaching arm extending in parallel with the lever arm and having a first concave indentation; said lever arm having a pressure projection for pressing down said flat cable at an end thereof and a pressure receiving portion at the other end for receiving a pressure from said cam portion of said movable member to flex in the same plane as that of said terminal, thereby producing a pressure between said contact projection and said flat cable; said cam portion having such a shape that the cam portion is out of contact with said pressure receiving portion of said lever arm when said movable member is at said open position, thereby making it possible to insert said flat cable and in contact with said pressure receiving portion when said movable member is at said closed position; said pressure receiving portion having a shoulder and a second concave indentation continued from said shoulder so that when said movable member moves to said closed position, said cam portion provides said pressure receiving portion with a highest pressure and when the movable member reaches said closed position, said cam portion rests between the first concave indentation and the second concave indentation while maintaining a pressure that is lower than said highest pressure.
