ABSTRACT:
Apparatus for use in terminating flexible flat conductor cable or the like with contacts having a termination section for terminating a conductor portion thereof includes a flexible, generally U-shaped carrier strip for carrying a plurality of longitudinally spaced ones of the contacts, an anvil assembly, a ram assembly, a stripping assembly, and a guide and positioning assembly. The guide and positioning assembly comprises a support surface and adjustable positioning stops for predetermining the lateral location of the flexible flat conductor, as well as a clamp for clamping the flexible flat conductor on the support surface with its conductor elements extending over termination pockets of the anvil assembly. These pockets are defined by anvil die inserts in slots of an anvil die block and generally U-shaped, longitudinally spaced projections on pressure pads. The die block cooperates with the carrier strip to locate in contacts in the termination pockets, and a stripper bar of the stripping assembly is movable to cammingly peel the carrier strip from the positioned contacts. The ram assembly includes a slotted ram die with ram die inserts positioned therein to present die faces toward the termination pockets. During termination, the ram enforces termination of conductor elements of the flexible flat conductor while progressively lowering the projections to progressively expose prongs of the contact. Bending of the prongs out of their common plane is inhibited by the legs of the projections and lateral support for the contacts during lancing is provided by those legs. The bias on the pressure pad enforces dislodging of contact portions lodged in the pockets during termination.
