The electronic contents inside an automobile are increasing day by day and posing newer challenges in terms of managing the wiring harnesses that connect them.
A wire harness is a specially designed system that keeps numerous wires or cables organized. It is a systematic and integrated arrangement of cables within an insulating material.
The purpose of the wiring assembly is to transmit a signal or electrical power. Cables are bound together with straps, cable ties, cable lacing, sleeves, electrical tape, conduit, or a combination thereof.
Rather than manually routing and connecting individual strands, the wires are cut to length, bundled, and clamped to the terminal or connector housing to form a single piece.
The wiring harness is created in two stages. It is designed in a software tool first and then the 2D and 3D layout is shared with manufacturing plants to build the harness.
The specific process of vehicle wiring harness design involves the following steps:
First, the electrical system engineer provides the functions of the entire electrical system, including the electrical load and related unique requirements. The state of the electrical equipment, the installation location, and the form of connection between the wiring harness and the electrical equipment are all key considerations
From the electrical functions and requirements provided by the electrical system engineer, the complete vehicle electrical schematic is created by adding components required for a function and connecting them together. The functions which are commonly used across multiple vehicles in an architecture platform are stored together.
After the schematic is defined, the wiring harness design is created. In one platform, the end customers can have a variety of requirements. It is very time-consuming and expensive if different designs are created for each end user's requirements separately. So, the designer takes care of the multiple variants while designing the wiring harness.
At the end, a 2D representation of all the wiring designs is created to show the way different wires are bundled and how the bundles are covered to secure the wires.
These designs can interact with 3D tools for the import and export of details. The wire lengths can be imported from the 3D tool and the end-to-end connection details are exported from the wiring harness tool to a 3D tool. The 3D tool uses these data to add passive components such as straps, cable ties, cable lacing, sleeves, electrical tape, and conduits in relevant locations and send them back to the wiring harness tool.
Point-to-Point Cable Bundles
The simplest type of wiring harness uses point-to-point cable bundles and packages them together into a single harness assembly. Cable bundles can be packed together using adhesives, tapes, sheathing, or mesh jackets. The cables used in these bundles could be off-the-shelf cables, custom cables, or a combination of these. Interconnect topology that usually arises from this is point-to-point because of the direct connections via these cables.
Bifurcated Cables
Cabling coming off of a connector can be bifurcated, where a single connector has wiring splitting off to two different destinations. This would be used to have a single receptacle on one PCB connecting to at least two other PCBs. This is a more sophisticated type of wiring harness that involves mixing and matching connectors and receptacles across different boards.
Flex Printed Circuit (FPC) Cable
Flex ribbons can also be used as wiring harnesses, which would allow a mix of edge connectors, surface mount connectors, and even through-hole connectors to interface with a group of PCBs. Flex connectors have an advantage and that they are very flat and so they may be useful in very low profile products. In some products, a wire bundle in a standard wiring harness simply won't fit in the design, so a flex cable becomes a very attractive option.
Automotive Applications: To simply starting an automobile, motorcycle, truck, tractor, and so on relies on a variety of electrical devices and electronic controls to transmit electrical power and signals to turn the engine over and execute ignition. The transmission of those electronic signals is part of a massive wiring network that allows vehicles to function. That functionality is accomplished through wire harness applications that merge the engine management system, electronic controls, lighting, air conditioning, power steering, electric windows, power brakes, entertainment, and audio system, and so on into an efficiently operating and functioning vehicle. With many electronic units on board, it's no wonder an average car has thousands of wires extending over a mile to connect operating systems and devices. Wire harnesses connect those devices and supply electricity and electronic signals throughout the vehicle.
Manufacturing: Complex wiring, networks, cabling systems and drive robotic and automated production and assembly lines in today's manufacturing facilities and plants. Wire harnessing applications connect signal and power conductors that control various systems along the same production line or within the same area. Wire harnesses ensure proper seal cabling, connectivity, and wires to ensure production is fully optimized.
Medical Applications: In the healthcare domain, electronic medical equipment, instruments, and devices are subject to heavy use and varying degrees of low and high intensity. The wire harness applications fixed in these devices must be durable, biocompatible, and adaptable. Whether the device is a radiological or imaging equipment, defibrillator, pacemaker, or drill, it must function efficiently on demand without failure. Because of the myriad of applications, wire harnesses for the medical and healthcare sector come in all sizes and shapes. They differ significantly from other wire harness assemblies used in different industries. Wire harnesses for medical applications must be bio-sensitive and comply with FDA regulatory controls and guidelines.
Communication Systems: Global connectivity demands an infrastructure that can send and receive data instantaneously worldwide. Communication systems depend on customized and personalized harnesses for a wide range of applications through an array of technologies. Wire harnesses are crucial components in the assembly of broadband networks, hubs, optical networks, routers, peripheral equipment, repeaters, modems, and much more. Wireless communication applications include RF, DSL routers, and satellite receivers.
Military Applications: Wire harness capabilities for any military application must meet stringent DoD (Department of Defense) specifications. Cabling and wiring used in military equipment are designed for applications subject to extreme environments and conditions. Wiring harness manufacturers in India must manufacture military wire harnesses with components—wires, connectors, terminals—specified and approved for demanding military applications.
