Abstract

This connector permits high-density inter connection between coplanar surfaces along the edges of the surfaces. Leaf springs 10 are positioned on either side of an opening for the insertion of the edge of board 12. These springs are controlled by cam plate 14 which is actuated by the contact of wedge-shaped cam member 16. This engages and disengages a spring-steel louvered member 18. With cam 14 out of contact with member 18, springs 10 are separated sufficiently to permit board 12 to be inserted into the opening with a zero insertion force. Once board 12 is in position, cam 16 is moved to contact member 18 and this exerts force through plate 14 on springs 10.

Leaf Spring Edge Connector

This connector permits high-density inter connection between coplanar surfaces along the edges of the surfaces. Leaf springs 10 are positioned on either side of an opening for the insertion of the edge of board 12. These springs are controlled by cam plate 14 which is actuated by the contact of wedge-shaped cam member 16. This engages and disengages a spring-steel louvered member
18. With cam 14 out of contact with member 18, springs 10 are separated sufficiently to permit board 12 to be inserted into the opening with a zero insertion force. Once board 12 is in position, cam 16 is moved to contact member 18 and this exerts force through plate 14 on springs 10. This brings pressure to bear on the arched central position 10a of the springs so as to cause the bent tips 10b to contact and slide along the board to make electrical connections with it. The spring members 16 are arranged in pairs which are joined by a rubber spacer 20.
