Intrinsic certification assembly technique for wiring components into an

Abstract

A technique is described for completely and positively wiring components into mass produced machines, such as washing machines, dryers and the like. The subject technique encompasses improved contacts, connectors and a wiring harness all of which are individually and collectively adopted to provide a readily ascertainable positive visual indication of a full mating condition and which will prevent further assembly of components if not initially fully assembled in the proper relationship. Each subassembly of a connector and related component includes keying means allowing only correct assembly and mounting in the machine plus visual indicators which verify correct assembly at each step. The connectors preferably have housings which can be produced in great lengths and cut to the desired shorter lengths. These housings also include strain relief means for the associated conductors and may be hermaphroditic. Each contact terminal includes an insulation displacing conductor engaging portion, enabling rapid connection with associated conductors, and a matable portion adopted to readily engage several different size mating contacts. In the preferred embodiment, the contact terminal is also completely hermaphroditic both in the manner it mates with other contacts and with regard to which end makes an insulation displacing engagement with an associated conductor.
