Abstract: A wire harness assembly work cell includes a wire harness assembly work table with a pneumatically powered or spring-fed universal applicator tool for mass terminating sets of wires into insulator wafers. The insulator wafers may be assembled in stacks to form cable-end connector headshells. Insulation displacement terminals (IDT) are designed to receive wide ranges of wire diameters so that larger varieties of wire sizes may be received into these connector assemblies while using fewer different sizes of terminals, thus reducing the number of items in a bill of material (BOM) and substantially reducing the volumes and overhead costs of testing and quality control documentation dedicated to each individual BOM item.

Abstract: A computerized discrete wire inventory indexing system organizes and automates the intake of wiring used in a wire harness assembly work cell. Functions in a work cell may be duplicated into a second arrangement symmetrically opposite to a first arrangement so that an indexing system in accordance with the invention may operate between or alongside the adjacent work cells to execute its tasks in tandem and produce pairs of wires to be used within the two work cells. The wire indexing system operates with a tandem wire pulling machine on a movable shuttle that grabs pairs of wires from the indexing system and draws them to length. Both the shuttle and the wire indexing system may includes fixtures for stripping and terminating wires by crimping terminals onto prepared wire ends. Computer control enables rapid and correct wire production and efficient process change-overs.

Abstract: An insulation displacement connector (IDC) includes clamping terminals or contacts which make two redundant contacts into the wires instated into them. The inventive contact comprises a flat strip section, four J-shaped cantilevers each having a straight section and an arcuate section, with a portion of each of said straight section attached to the flat strip section, and the cantilevers arranged into two pairs each having two arcuate sections curving towards each other to form a pincer section. The two pincer pairs face toward each other on the strip. A wire received into both pincer pairs is held securely because any tension applied to the wire forced at least one pincer set to clamp together harder on the wire. The inventive contacts reside in an insulator housing of an insulation displacement terminal (IDT) connector assembly which can accept wires of mixed sizes.

Abstract: A floating pin form board assembly to aid wire harness assembly includes a first embodiment with a work block and chambers containing floating pegs which may reside in retracted or extended positions based on perforations in a wire routing form sheet which allow or prevent retracted pegs from rising to extended positions. Extended pegs may be locked into their extended positions by means of a slidable latch plate, and stop features in the pegs prevent them from escaping past their extended positions. Alternatively, a floating peg form board assembly includes a perforated sheet and first, second, plates third plates each having apertures spaced apart in congruent arrays and a plurality of floating pegs having stop features, and a slidable latch plate having an array of keyhole slots complementary to apertures in one of the other perforated plates, with the latch plate used for locking the floating pegs into retracted or extended positions.

Abstract: A configurable modular work space for a wiring harness assembly system comprises a computerized wire harness system controller and bulk wire supplies associated with a programmable discrete wire inventory retainer. One or more multiple wire pull-through mass terminators and a sequential wire termination apparatus are positioned proximal to a universal wire harness board, with a programmable mass terminator tooling unit cutting wire to length during a mass termination cycle. The multiple wire pull-through mass terminator leads to a first IDT connector nest, and then onto the universal wire harness board. A universal wire harness board comprises a floating pin board assembly positioned to interface with a second IDT connector nest, and the floating pin board assembly comprises a plurality of floating pins arranged in an array, which may be individually locked in extended or retracted positions for receiving wires during assembly of a wire harness according to wire harness specifications.
