Wire harness

Cables for carrying power, data, control, or other electrical or optical signals are often bundled to simplify their handling, connection, or routing. It is well known to utilize a harness including rings, straps, collars, or an outer sheath around a plurality of cables to form and maintain a bundle comprising those cables. Electrical wire harnesses have been manufactured for years and are used extensively in the automotive, appliance, electronic, and telecommunication industries. Cable harnesses have generally fallen into one or two groups, those which merely secure a number of cables or other workpieces together in a bundle and those which secure one or more workpieces which also incorporate a device for affixing the cable harness to another object. Generally, wire harnesses include at least one multicircuit connector terminated to an insulated multiconductor cable. An electrical wiring harness typically comprises a bundle of individual wires of varying gauges, impedances, and types, all arranged in a particular order. These wire harnesses are bound together in order to facilitate the installation, repair and maintenance of the wires, and the connection of multiple remote systems. Most cable harnesses employ one piece or two piece mass terminated connectors including insulation displacement type electrical contacts. Insulation displacement connectors are well suited for use in automated cable assembly. Miniature cable harness assemblies are commonly used to connect to input/output ports at the rear of integrated circuit cards. A common design for such harness assembly includes a connector frame holding multiple contacts, a circuit board extending rearward of the connector frame, and a stripped cable held to the rear of the board. A wire harness provided on a body of an automobile is attached to various types of electrical and electronic devices. A wire harness is provided on the rear door of an automobile to operate the tail lamp, the rear wiper, etc. A wiring harness for use in an automobile usually comprises a plurality of electric wires and connectors and has a complicatedly-branched geometry.
