Electrical connector for flat cables

Claim 1

An electrical connector for a flat cable having an upper surface and a lower surface, comprising: a dielectric housing having an opening for receiving an end of the flat cable in a cable-insertion slot; a plurality of first terminals mounted in the housing, each first terminal having a generally U-shaped configuration defining a base leg and an upper leg, both legs being fixed in the housing and defining a mouth therebetween coincident with the opening in the housing for receiving the end of the flat cable, a flexible contact arm extending from a distal end of the base leg near the opening in the housing and into said mouth to a free end of the arm which defines a first contact section facing upwardly into the cable-insertion slot, and the upper leg having a pivot section near a distal end thereof facing the base leg; a plurality of second terminals mounted in the housing, each second terminal having a base fixed in the housing and a bifurcated arm flexibly connected to the base and extending toward the opening in the housing, the bifurcated arm including an upper arm extension and a lower arm extension having a second contact section near a distal end thereof facing upwardly into the cable-insertion slot; and an actuator pivotally mounted on the housing for movement between an open position and a closed position and having a pivot section engageable with the pivot sections of the upper legs of the first terminals and a pressure section facing downwardly toward the cable-insertion slot, said actuator in its open position allowing the flat cable to be inserted into said slot between the pressure section of the actuator and upper legs of the first terminals and the first contact sections of the first terminals and second contact sections of the second terminals, and said actuator in its closed position causing the pressure section thereof to engage the upper surface of the flat cable and bias the lower surface of the flat cable against the second contact sections of the second terminals while the upper arm extensions of the second terminals engage the upper surface of the flat cable and bias the lower surface of the flat cable against the first contact sections of the first terminals.
