A junction box is a device that protects a connection (the junction) of two or more wires carrying electrical current. This level of protection is needed to prevent fires and form reliable connections that stay tight over many years. Need to run a wire from every outlet or switch back to the main service panel is removed by junction box. Nowadays, junction box features with electronic module functionality. When a junction box is used for every electrical connection it is much easier to locate and repair any electrical problems appeared in the system. Every electrical connection should be inside a protective box that is easy to find and access and junction box is used for that.

Electronic systems for which power distribution is done by junction box are required to install advanced feature in vehicle. Therefore, it is expected to be a key factor responsible for driving the automotive junction box market. When a junction box is used for every electrical connection, it is much easier to locate and repair any electrical problem that is likely to arise. Junction box can be used to protect the essential wiring connections. Solid state smart junction box allows relays and fuses to work through electronic devices. These self-protecting devices improve quality and eliminate the service to fuse and relays. Safety and security is also controlled by various systems as ABS, ADAS, and central locking system. Hence, safety and security is key in the increase in the demand of junction box. A majority of vehicle breakdowns are caused by electrical failure. Failure in the junction box is likely to damage the entire vehicle as it is a major component of the electronic system.

The automotive junction box market can be segmented based on vehicle type, function, component, and geography.

Based on vehicle type, the automotive junction box market can be classified into passenger vehicles (PV) and commercial vehicles (CV). The Passenger vehicles segment can be further sub-segmented into hatchback cars, sedans, multi- purpose vehicles (MPV), and sport utility vehicles (SUV). The commercial vehicles segment can be split into light-weight commercial vehicles (LCVs) and heavy commercial vehicles (HCVs).

Junction box is categorized in two types: Passive junction box and Smart junction box. Smart junction box uses microcontroller-based technology to perform functions such as automotive power switching and vehicle body control. A junction box is used to transfer power from the powerhouse of the vehicle to every single component. It switches the distribution of power at the junction. As vehicle body controller, it helps the electronic system to function properly and maintain electronic systems’ good condition.

Components used in a junction box include AC power plugs and sockets, cable tray, electrical conduit, mineral-insulated copper-clad cable, multi-way switching, steel wire armored cable, ring circuit, and thermoplastic-sheathed cable.

In terms of geography, the automotive junction box market can be segmented into North America, Europe, Asia Pacific, and Rest of the World (ROW). Asia Pacific accounts for a major share of the global automotive junction box market, due to the high adoption rate of automotive junction box and the booming automotive sector, leading to an increased production of vehicles with junction box, especially in China and India.

Key players operating in the global automotive junction box market are Aisin Seiki Co Ltd, BorgWarner, Continental Corporation, Delphi Automotive PLC, DENSO Corporation, Eaton Corporation plc, Hilite International, Hitachi, Maxwell Technologies Inc., Mechadyne International Ltd, Robert Bosch Gmbh, Schaeffler Technologies Ag & Co. Kg, Valeo S.A., Johnson Controls Inc, and Mitsubishi Industrial automation.
