Fields and Applications of Each Harness Industry

Whether it’s traditional consumer electronics, home appliances, or emerging technologies such as new-energy vehicles, foldable-screen phones, 5G, or the Internet of Things, what all these aim to achieve is the connectivity among devices themselves, between devices and people, and between people and data. All of this hinges on wiring harnesses. As 5G, new-energy vehicles, and smart terminal interconnectivity continue to develop rapidly, the wiring harness industry is facing new challenges. At the same time, how to improve wiring harness manufacturing processes to meet evolving market demands has become an urgent issue that the industry must address. The main types of wiring harnesses produced across various industries fall into four categories: medical wiring harnesses, automotive wiring harnesses, and industrial control wiring harnesses.

Automotive wiring harness:

The automotive wiring harness is the backbone of a vehicle’s electrical system, also known as low-voltage cables. Conventional automotive wiring harness products feature properties such as heat resistance, oil resistance, and cold resistance. At the same time, they are highly flexible and designed for internal vehicle connections, capable of withstanding high mechanical strength and operating in high-temperature environments. Moreover, with the advancement of intelligent technologies, today’s cars are no longer simply engines with rows of seats; they’ve evolved into sophisticated computers equipped with capabilities for office work, entertainment, and connectivity to virtually everything around them. As a result, automotive wiring harnesses now place even higher demands on the electrical performance of wires and require greater quantities. The quality must meet the zero-defect requirements of TS16949, and manufacturers must provide a 10-year valid warranty period. With the growing popularity of new-energy vehicles, demand for these vehicles has surged recently. Suppliers of such vehicles are expected to offer comprehensive services—including complete cable design and development solutions. Therefore, any new entrepreneurs planning to enter this industry must thoroughly understand the entry barriers and stringent requirements for automotive wiring harnesses.

Medical wiring harness:

As the name suggests, medical wire harnesses are wiring assemblies used to connect medical devices and equipment. The wires employed in these harnesses are all made from high-quality materials that have been certified according to standards such as UL, VDE, CCC, and JIS. Commonly used medical connectors include wire-to-board connectors, D-SUB connectors, header and socket connectors, and aviation plugs. The connector brands typically chosen are international ones like TYCO and MOLEX. These harnesses generally comply with the 13485 medical certification standard, and most of the materials used also require sterilization. Therefore, entrepreneurs planning to enter this industry must thoroughly understand the entry barriers and requirements for medical wire harnesses. According to a research report by BCC Research, the global market for home healthcare devices is experiencing steadily increasing annual growth rates, and medical electronics are poised to become a new growth driver for connector applications.

Wiring harness for industrial control products:

This primarily refers to electronic wires, multi-core cables, ribbon cables, and other components housed within equipment cabinets—often used in industrial UPS systems, PLCs, CPs, frequency converters, monitoring systems, air conditioners, wind power equipment, and similar applications. Currently, this is one of the most widely practiced cable harness industries, with an extremely diverse range of sub-products (including sensors & industrial control systems; network communications; temperature control and air conditioning; air-conditioning systems; LEDs and lighting; rail transit; marine and offshore engineering; renewable energy sources; measurement and testing equipment; packaging and logistics conveyance). It covers the broadest spectrum of product types and has relatively few stringent requirements in terms of certification or scale. However, entrepreneurs entering this field need to have a solid understanding of its industry characteristics. The typical production involves small batches of many different products, and there’s a significant demand for branded components. Consequently, selecting the right supply chain becomes particularly critical—especially when it comes to connectors, where the variety of brands and models required is exceptionally extensive.
