ABSTRACT:
A connector structure for making electrical connection to a plurality of individual conductors contained within a flat wire cable has a plurality of fixed length flexible contact members assembled in parallel relationship in an insulation base. Each of the contact members has a nose portion at one end extending through the base and a piercing tail at the other end extending above the base and contained in a slot formed in a side extending from the base. A flexible connection region connects the piercing tail to the nose. Each of the flexible connection regions of all contacts are pre-bent in the same direction to accommodate a variable lateral spacing between the piercing and nose portions of each contact element. Alternatively, the contacts may be designed to bend in the same direction during installation. The central region of each contact is engaged by a contact locking plug which is frictionally held in the base. A plain cover is latched in one of the positions on the base and can press the individual conductors of a single flat cable into piercing contact with each of the contacts in the base. The cable is automatically aligned relative to the piercing tails by alignment projections extending from the base. The plain cover may be loosely held on the base and snapped in place when pressing the cable onto the contact tails for closed face assembly. Alternatively, the cable can be pressed onto the tails by a conventional tool and the cover later snapped in place for an open face assembly. A strain relief cover is snapped onto the plain cover if desired and latches onto latching projections extending from the plain cover. The base contains guiding projections for receiving and positioning both the plain and strain relief covers and contains cam projections for holding the covers in place.
