Structure and Application Copper foil soft connection is made up of multiple pieces of T2 purple copper foil stacked and welded to both ends. Drilling can be carried out according to customer requirements. Molecular diffusion welding is a precision welding technology that promotes mutual diffusion and bonding between atoms of a workpiece under high temperature and pressure conditions. A high-strength joint is formed while maintaining no visible deformation of the workpiece.
Therefore, copper foil soft connection is an excellent electrical conductor and is usually used in related industries such as new energy vehicles, wind power generation, photovoltaic energy storage, electric locomotives, and complete transmission and distribution.
Customized production can be customized based on customer drawings/samples and provided systematic service support
product introduction
Flexible connection of copper and copper foil at both ends is an innovative and efficient flexible conductive solution in the fields of power and new energy. It combines the excellent flexibility of traditional copper foil soft connections with the excellent mechanical strength and electrical connection reliability of press-welded copper tube terminals. This product is mainly composed of multiple pieces of high-purity T2 purple copper foil stacked, with a copper content of more than 99.95%, ensuring extreme electrical conductivity 。Its unique feature is that the copper foil is press-welded into the copper tube at both ends through a special process to form a firm and low-resistance terminal connection, replacing the traditional plate press-welding or soldering connection method. This design not only optimizes the current path, but also greatly improves the mechanical stability and installation convenience of the product.
Core technology: Pressure welding and copper tube terminal integration
The core advantage of this product lies in its innovative two-end pressing copper tube process. It combines:
- High-precision pressure welding technology: Similar to traditional copper foil soft connection, the copper foil body is manufactured using molecular diffusion welding (pressure welding) process 。This technology promotes the mutual penetration and fusion of copper foil molecules through high temperature and high pressure to form an integrated conductive area, avoiding false welding and stress concentration, and ensuring the overall conductive efficiency and mechanical strength. 。
- Crimp copper tube terminals: At both ends of the soft connection, the copper foil is not directly press-welded into a flat plate shape, but is accurately press-welded into a prefabricated copper tube or copper sleeve. This structure allows the connecting terminal to form a closed tubular shape, which not only increases the contact area, but also provides unparalleled mechanical protection and lower contact resistance. Crimp copper tube terminals can be drilled according to customer needs to facilitate bolting or docking with other equipment 。
The design of this copper tube terminal is especially suitable for occasions that require frequent insertion and removal, withstand greater mechanical stress, or require a more compact connection, significantly improving the overall reliability and service life of the product.
