Electrical connector for flexible circuit boards

Claim 1

An electrical connector for the purpose of terminating lead wires on flexible circuit boards consisting of a long and narrow, frame-shaped component formed of an electrical insulating material having insertion chambers set in a row in the direction of the length at equal intervals from each other, a resilient connecting component which is formed of a conductive resilient material that is inserted into and affixed in each insertion chamber and which holds the lead wires, a longitudinally extending pressure insertion component formed of an electrical insulating material having on one side surface a series of parallel dovetailing projections set like teeth of a comb in said pressure insertion component, said projections having lead in edges that fit into the insertion chambers of the frame-shaped component in positions corresponding to the insertion chambers and that hold the lead wires by affixing the resilient connecting component which holds the lead wire, the first and the last dovetailing projections of the series being substantially the same length which is longer than any of the other dovetailing projections of said series, said other dovetailing projections progressively descreasing in length so that the next longest projection is adjacent to said first projection and the shortest is adjacent the last projection, said first and last projections functioning as guides when the pressure insertion component is inserted into the frame-shaped component, and said other projections providing smooth insertion due to the sequential insertion of each of said other projections into its respective insertion chamber.
