The arrival of the sharing economy will change people's way of life, will bring the industrial revolution, there are also some Internet companies began to invest in enjoying every car, car sharing because of investment reasons, will be light, safe, energy-saving models, which will be a new growth point of the automobile industry. Copper soft connection is suitable for all kinds of high voltage electrical appliances, vacuum electrical appliances, mine explosion-proof switches and automobiles, locomotives and other related products for soft connection, using bare copper wire or tinned copper braided wire (stranded wire), made of cold pressing method. The interface of the soft connection of copper bar is welded by molecular diffusion welding technology in one time. The product has the characteristics of good quality, strong conductivity, large current, small resistance value and durability. It is widely used in metallurgy (such as electrolytic aluminum, electrolytic zinc, electrolytic copper), chemical industry (such as electroplating), transformer engineering (such as power plant), power equipment (such as transformer, distribution cabinet). Each auto brand must increase its efforts to develop new energy vehicles and upgrade products to meet the needs of the development of the sharing economy.

Electric vehicle electric power system battery current control requirements are high, for their own charging speed development requirements are high, the general conductive connector can not withstand such a large voltage, so this new type of electric new energy vehicles are the use of copper soft connection soft connection, also known as the enterprise use copper bus expansion joint, it can improve to adapt to the society of high strength current and voltage. Conductive large current copper soft connection Soft connection, what is the role of copper busbar expansion joint?
The expansion joint plays an important role in regulating the society to avoid different stresses on enterprise equipment joints, which can mainly be used as compensation for the displacement (axial and radial displacement) caused by thermal expansion and contraction of the pipeline. Used to achieve protection and the normal operation of the pipeline and information security. The shrink joint is to prevent the switch or bus from being broken due to short circuit or hot account cold contraction, and the elasticity of the expansion joint is used to protect the environment.
The expansion joint is divided into the expansion of the system bus and equipment and the expansion of the bus and the bus according to the use of different occasions, and according to the material of the joint to choose, such as the busbar is aluminum, the equipment and the joint is copper works with aluminum-copper expansion joint, the busbar is aluminum with aluminum-aluminum expansion joint, and the copper busbar can be copper-copper expansion joint. Aluminum and copper should not be directly bonded, there is no part to be barely used must be the copper busbar connection joint part of the hot tin treatment, that is, between the two kinds of copper and aluminum are metal enterprises have a layer of students are not easy to be corroded the overuse of metal "tin" to prevent the electrochemical research process of copper and aluminum.
Processing technology:
1. Various specifications of copper tape soft connection, the use of non-molecular diffusion welding process to maintain the original conductivity of the material, the use of advanced German welding process, solder joints are firm, not easy to be deformed by external force, suitable for electric vehicles, buses, new energy vehicles, high current requirements for connector performance... The conductive contact surface can be silvered, tinned or tinned...
