Weaving car for the future of the new era car ~ ~ sumitomo DianGongSuo painted

Before the display field are pushing anti-corrosion technology, need to understand the corrosion mechanism of aluminum.Aluminium wire beam is connected to the terminals of the aluminum wire and copper base material.Contact with copper and aluminum parts once attached to the salt water and electrolyte, will occur due to different kinds of metal corrosion, weld precipitation of aluminum.Since the occurrence of corrosion, and the elder obstruction of wiring harness aluminum, one of the main reasons.So for aluminium wire bunch of car, people think that the different kinds of metal corrosion caused by contact, is the important subject must be solved.Field use of cars against harsh environment, has launched a field survey.

"For corrosion environment, the most worrying thing is salt water electrolyte, such as adhesion, in electrolyte easy adherent region, we aimed at aging vehicle launched an investigation.Specifically, including chloride to more in the Middle East, highlighted attachment of de-icing salt causes corrosion problem of North America, and the storm cause vehicle flooding problems such as southeast Asia and other regions.We quantify the salt concentration, made clear the occurrence of corrosion, and the salt content of the causal relationship between "(the mountains)

At the same time, through the investigation, we found that no matter how the environment cannot exist in the vehicle to avoid salt attached parts, located in the area of terminal pressure welding part of the wire connection will be corrosion.Subject became clear.That is in the car use aluminium wire bundle, how to establish the aluminum wire terminal pressure welding of anti-corrosion technology.Through various discussions, we believe that in addition to the corrosion resistance of aluminum conductor exposed parts, after the terminal side also need to be done without clearance protection, therefore, including pressure welding department, the terminal backend, whole adopted resin moulding method.

In this way, sumitomo electric group "on the fate of a large project" the output of aluminium wire bundle, compared with other competitive enterprise, its technical comprehensive strength is more outstanding, so admired, implements the vehicles carrying in 2010.From material development to production technology, pursuing goal.The sumitomo electric group comprehensive strength is gaining recognition.Now, sumitomo electric group of aluminium wire bundle to Japanese supply of many car manufacturers at home and abroad, is not only in Japan, Europe and the United States and other countries around the world also.The reliability of the highly acclaimed, for the initial purpose of lightweight car body at the same time also produced.CO₂Had great progress.

In addition, sumitomo electric group from the earlier period is put forward the concept of "whole aluminium wire bundle", the group has been to promote the research and development of aluminium wire bundle independently.In 2015, is one of the results of carrying on the vehicle's "high strength aluminum wire.Before that due to the vibration problem of how to apply aluminum wire bundle to become a major topic around the engine.Our goal is to produce to withstand the engine vibration buckling of aluminum wire bundle, the final finished product and the copper wire with the same size, in terms of strength and conductivity, and have no regret to play out of the sumitomo electric group of superb technical strength.

Look to the future of the auto industry, due to the progress of electronic technology, it is considered that harness the carrying amount of will expand further, at that time, the growing importance of lightweight aluminium wire bundle will be further improved.In addition, support for gradually become the world trend of the electric car is also essential.Current, because of the large electric cars need to aluminum wire must be need to increase the diameter."Control diameter increases at the same time, also can support the large current of aluminium wire" otsuka (the above) development is also a big issue.In addition, electric cars need to consume a lot of power, so for heating the solution of the problem is one of the development project.

However, regardless of the existence of the car and the structure change, energy and information transmission effect in the car interior wiring harness, even change its shape, it as a "vehicle infrastructure" (the water) this is a constant.However, you must get rid of the parts according to the demand of the auto makers to provide the way it is beyond doubt."The group has always been based on auto makers Tier1 (tier one suppliers) in the form of a business, but must be aimed at Tier0.5 in the future.How to change, the proposal again?We will change the car personally.I think this is also the mission of the group "(the above) inoue.

Sumitomo electric group in addition to the car maker, will also be able to cooperate and electric power, communications and other industries, is also our a big advantage.By giving full play to the advantages of these other companies are not actively advocating and popularizing new additional value and service.This will and attitude will develop the auto industry a new future.
