Harness components used in connecting wires are available in a number of variations to deal with high temperatures, vibration, waterproofing, noise, and other severe conditions to which they are exposed

Achieving the compact structure with high performance by suppressing insertion loss and reflection loss while securing sufficient shielding performance.  Hybrid-type connector for both coaxial cable and electric wire for vehicle, and the connector for circuit boards, are also available.

Achieve both miniaturization and high reliability. These connectors are used in engine compartment, exposed to heat and vibration from the engine, which is regarded as the most severe environment. There are some hybrid connector variations containing power circuits such as 2.3mmⅡ and 4.8mm terminal.

Miniaturized by using mat seal for wires. Control unit is mounted in engine compartment, so applying strain relief structure to minimize the thermal expansion affect on soldering portion. This results in high contact reliability.

The wires used in wiring harnesses have evolved in response to the need for greater compactness, reduced weight, and high-speed, large-volume communications. Sumitomo offers an industry-leading lineup of wire products.

High-Voltage Wires

Employed for the high-voltage circuit installed in next-generation vehicles, for example, hybrid vehicle (HEV), plug-in hybrid vehicle (PHV), electric vehicle (EV) and the like.  Employed as the harness component for supplying electricity to various devices such as high-voltage battery, motor, and inverter.

Copper and aluminum are used for forming the conductor.  The use of aluminum instead of copper has resulted in substantial weight reduction while maintaining high reliability.  The insulator exhibits 2 types of excellent heat resisting property, for example,  resistance against temperatures of 120℃ and 150℃.  It can be used in the high-temperature environment of the vehicle.

Referring to the crosslinking process (N.B.) applied to the insulator to improve the heat-resistant property of the wire, the heat-resistant wire  that allows crosslinking with steam (developed through the electron beam irradiation crosslinking process, which requires an electron beam irradiation device) was developed and made into a product.
N.B. : Crosslinking among chain macromolecules

Shielded Cables

Employed for control circuits and sensors, which are installed in various types of automobiles such as gasoline-powered vehicle, hybrid vehicle (HEV), plug-in hybrid vehicle (PHV), and electric vehicle (EV). In addition to the function of supplying electricity to the respective circuits, the cable has the shield layer functioning to shield external noise. Noise shielding ensures prevention of circuit malfunction.

The shield structure has three types including braided structure, horizontal winding structure, and metallic foil tape, which can be selectively used in accordance with the required noise shielding level. Copper is used for forming the braided structure and the horizontal winding structure. Copper and aluminum are used for forming the metallic foil tape. The number of wire cores ranges from 1 to 8.

For reduction of thickness and weight of the shield cable, the thickness of the insulator of the wire core is reduced. Thinning of the sheath for protecting the shield layer secures thinning and weight reduction of the shield cable while maintaining high reliability.

Aluminum Electric Wires

Aluminum Electric Wires are the wires that replaced conductor materials from copper to aluminum.
These significantly reduce the weight of the wire harness and help improve fuel efficiency.

Sumitomo offer a lineup of standard aluminum wires and high-strength aluminum wires as two kinds of automotive aluminum electric wires.
high-strength aluminum wires can be used as signal lines and for engine wiring harnesses.It is possible to use two types of aluminum wires properly according to the purpose of use, location, and required performance.

SWS is the integrated supplier about aluminium production and has developed the aluminium alloy that is compatible with improved electrical condectivity and tensile strength according to the purpose of use.
