ABSTRACT:
A contact has a contact portion, a backing member, and a leg integrally connected together and stamped and formed from sheet metal. The contact is crimpable to a flat conductor cable having a conductive layer with first and second insulating layers disposed on the opposite sides thereof. The cable is disposed adjacent the contact with the first insulating layer toward the backing member so that a region of the backing member overlies the conductive layer, with the second insulating layer toward an extended end portion of the leg, and with a cross-sectional section of the cable adjacent a base portion of the leg. The leg is deformed to cause the cable to be pressed between the end portion and the region of the backing member and to cause the extended end portion to pierce the second insulating layer and make electrical contact with the conductive layer. Continued deformation of the leg causes the end portion and the region of the backing member to converge at an angle having an apex directed generally toward the cross-sectional section of the cable. When the contact is completely crimped to the cable, the extended end portion of the leg and the region of the backing member are disposed in an overlapping relationship with the cable retained therebetween such that any tendency toward relaxation by the contact which might otherwise be detrimental to the electrical contact of the extended end portion of the leg with the conductive layer of the cable is resisted by the overlapping relationship and any relaxation that might be allowed by the overlapping relationship would be in a direction to enhance the quality of the electrical contact.
