What is the difference between copper foil soft connection and copper bar hard connection?
As the name implies, soft connection is a kind of soft conductive device. The soft part is to prevent the switch or bus from breaking because of short circuit or hot account cold contraction. It uses the elasticity of soft expansion joints to protect the switch or bus. It is also unrestricted in the angle of assembly. Hard connection is the same as soft connection, but it has no advantages of soft connection and can only be fixed in a certain position. Copper foil soft joint has good plasticity and high strength, easy welding, good corrosion resistance, and can withstand cold and hot pressure processing well. The unit price of soft copper bars is higher than that of stamped hard copper bars.
Reason analysis:
1. There are differences in the processing methods between soft copper bars and hard copper bars. Because soft copper bars are formed by laminated multi-layer copper foils, molecular diffusion is used in the welding process. This kind of welding equipment is mainly used in the welding of soft copper bars. Generally speaking, the two ends of the soft copper bar are connected areas, so it is necessary to drill by welding, punching and installation in application. In this process, the production cost must be processed equipment processing costs and labor costs, which is a reason for the unit price increase. In addition, the insulating requirements for the surface of the flexible connection copper bars are also strict, and special casing is needed, which will also increase the production cost.
2. The quality requirement of soft copper platoon is different from that of hard copper platoon. Soft copper platoon is used in new energy vehicles. The quality and performance requirements of products are very high, because this is related to the stability of power batteries, which manufacturers dare not slacken at all.
