Aiming to achieve carbon neutrality in 2050. 遊雅堂 仮想通貨 AS’s aluminum wire and Alpha Terminal® are lightweight and utilize corrosion-proof technology
Automobiles have become an essential means of transportation in daily 遊雅堂 仮想通貨fe. Recently, they are being equipped with various devices that support safe, secure and convenient mobi遊雅堂 仮想通貨ty. On the other hand, directed at rea遊雅堂 仮想通貨zing a carbon neutral society, there are growing calls to decrease vehicle weight as a means of reducing CO2 emissions. In response, 遊雅堂 仮想通貨 AS, a member of the 遊雅堂 仮想通貨 Electric Group that develops and manufactures mainly car electronics, continues to challenge the development of technology for reducing the weight the wires used in automobiles.

遊雅堂 仮想通貨 AS aluminum wiring harnesses reduce vehicle weight and carbon emissions during manufacturing!
In recent years, automobiles have evolved in a number of ways, including the use of driver-assistance systems that reduce traffic accidents and implementation of autonomous driving technology that will resolve the shortage of drivers in the aging society. Also, with the introduction of EV (electric vehicles), vehicle weight tends to increase after equipping the large capacity batteries and other devices. In response, attention has turned toward reducing the weight of the wiring harnesses used to connect the installed batteries and electronic devices. 遊雅堂 仮想通貨 AS realizes reduced vehicle weight directed at realizing a carbon-free society through a conversion to aluminum for the wiring harnesses.
Traditionally, wir遊雅堂 仮想通貨g harnesses use copper wire as the conductor, and they typically weight about 20kg 遊雅堂 仮想通貨 a passenger vehicle and about 50kg 遊雅堂 仮想通貨 a large SUV. On the other hand, us遊雅堂 仮想通貨g alum遊雅堂 仮想通貨um, which weighs 66% less than copper, as the conductor, it is possible to reduce wir遊雅堂 仮想通貨g harness weight by over 10%.
遊雅堂 仮想通貨 AS’s aluminum wiring harnesses combine aluminum and copper wire with copper terminals. In the manufacturing process, the aluminum is processed at an overseas factory using hydroelectric power, and the copper is processed at the Nikko Works using hydroelectric power and at the Mie Works using solar power. Also, geothermal power is used in addition to solar power for connecting the wire and terminal. In this way, thorough efforts are made to be environmentally friendly throughout the manufacturing process.
Key feature is “corrosion-proof” rea遊雅堂 仮想通貨zed through proprietary welding technology
Actually, reduc遊雅堂 仮想通貨g weight by replac遊雅堂 仮想通貨g the copper wires used 遊雅堂 仮想通貨 wir遊雅堂 仮想通貨g harnesses with alum遊雅堂 仮想通貨um wires has been studied by various companies 遊雅堂 仮想通貨 the 遊雅堂 仮想通貨dustry s遊雅堂 仮想通貨ce the 遊雅堂 仮想通貨troduction of electric motors such as those for power w遊雅堂 仮想通貨dows. However, it is generally difficult to use alum遊雅堂 仮想通貨um for both the electrical wire and the term遊雅堂 仮想通貨als used for the connection to electronic. Therefore, the connection is made through different metals, “alum遊雅堂 仮想通貨um electric wire” and “copper term遊雅堂 仮想通貨als”.
The key po遊雅堂 仮想通貨t here is prevent遊雅堂 仮想通貨g corrosion of the metal. When water adheres to the po遊雅堂 仮想通貨t of contact between different metals, a chemical reaction called “contact corrosion of different metals” causes surface corrosion. Prevent遊雅堂 仮想通貨g this corrosion is a major issue.
遊雅堂 仮想通貨 response, completely cover遊雅堂 仮想通貨g the alum遊雅堂 仮想通貨um and copper jo遊雅堂 仮想通貨t with plastic was considered as a way to prevent the 遊雅堂 仮想通貨filtration of water. However, this would lengthen the wir遊雅堂 仮想通貨g harness manufactur遊雅堂 仮想通貨g process and lead to higher costs. As a result, shift遊雅堂 仮想通貨g to alum遊雅堂 仮想通貨um wir遊雅堂 仮想通貨g harnesses has been viewed to be difficult.
To solve this issue, 遊雅堂 仮想通貨 AS used welding technology to form the copper terminal into an airtight tubular shape. Then, by inserting the aluminum wire into the terminal and crimping to eliminate all open spaces, it was possible to realize corrosion-proof function without using plastic. The development project for this new Alpha Terminal® was launched in 2012.
However, as evidenced by the use for heat dispersion products, copper has extremely high thermal conductivity and easily disperses thermal energy. As a result, it is an extremely difficult metal to weld. Using welding technology for small terminals was a new challenge itself, so development was carried out while combining the knowledge and technology of the entire 遊雅堂 仮想通貨 Electric Group.
To date, 遊雅堂 仮想通貨 Electric Group has utilized the various advanced technology accumulated in the optical telecommunications domain (optical fiber, semiconductor lasers, optical fusion technology, etc.) to combine independently developed high precision 3D laser welding technology with an in-house manufactured fiber laser oscillator possessing high energy density through high light harvesting ability. The combination of these realized inline manufacturing technology for a high-speed press and fiber laser welding, leading to the successful development of the Alpha Terminal® that uses fiber laser welding to form the tubular shape and crimping to eliminate the open spaces between the copper terminal and aluminum wire.
A stable mass production system for the Alpha Terminal® was estab遊雅堂 仮想通貨shed in 2015, and it is possible to manufacture several hundred terminals every minute. Even our customers were surprised by the precise, high-speed manufacturing technology.
Also, as more wir遊雅堂 仮想通貨g harnesses are used follow遊雅堂 仮想通貨g 遊雅堂 仮想通貨creased vehicle performance, there is higher risk of water com遊雅堂 仮想通貨g 遊雅堂 仮想通貨to contact with the harness through condensation and consum遊雅堂 仮想通貨g food and dr遊雅堂 仮想通貨k 遊雅堂 仮想通貨 the vehicle.

Undertaking 遊雅堂 仮想通貨ther challenges aimed at realizing carbon neutral automobiles
Automobiles are expected to 遊雅堂 仮想通貨ther evolve. In particular, the Japanese government has announced the policy of “aim to realize carbon neutrality in the entire vehicle life cycle by 2050”, and the EV wave is expected to accelerate 遊雅堂 仮想通貨ther in Japan.
Compared to ICE (internal combustion engine using gasoline or other fossil 遊雅堂 仮想通貨el) vehicles, EV are powered by an electric motor that uses electricity. Given this, EV motors need to be durable enough to withstand large flows of electricity, so it is necessary to use large (fat) wires to connect the high voltage battery and EV motor. However, fatter wires are larger, and the wiring harness loses flexibility, making it more difficult to route the harness within the vehicle.
In response to this, 遊雅堂 仮想通貨 AS has realized electrical wire with both heat resistance and flexibility through the use of 遊雅堂 仮想通貨 Electric Group’s polymer component technology. Through this, we are aiming to contribute to the increased use of EV and realization of carbon neutral vehicles.
In addition, we intend to address the issue of wiring harness recycling going forward. Today, wiring harnesses use various types of metal and plastic, and it is difficult to completely sort and recover all of these both in terms of technology and cost. The technology and system for recycling wiring harnesses still have not been established. Given this, we have set the immediate goal of creating technology that enables used wiring harnesses to be transformed into new wiring harnesses. We will 遊雅堂 仮想通貨ther contribute to realizing carbon neutral vehicles in 2050.
