Abstract
Abstract A termination method and apparatus for flexible flat conductor cable utilizing a contact having a pair of cable penetrating prongs for penetrating completely through a conductor of the flexible cable and a pair of biased abutment surfaces cooperable with the prongs for forming a crimp at a location remote from the penetration is disclosed. The prongs may be arranged in a manner to form a biased contact bridge therebetween after the connector has been attached to the cable. A die is employed to enforce cable penetration and bending of the prongs in a single movement lancing operation.
