Flexible laminated copper foil connector: Copper foil soft connection is a flexible conductive connector used for high current equipment. It is formed by welding multiple layers of copper foil sheets through polymer diffusion welding, silver based brazing, or pressure welding techniques, and has the characteristics of high conductivity, high current carrying capacity, and fatigue resistance. Its material is mainly T2 copper foil and T2 copper bar, and the contact surface can be tin plated or silver plated according to needs. The thickness range of copper foil covers 0.05mm to 0.5mm, and the specification parameters support customized design. This type of connector has a smooth surface, bright color, good oxidation resistance and corrosion resistance, ensuring stable operation in various harsh environments. This product plays a role in adjusting installation errors, shock absorption, and work compensation in power and electrical equipment. It is widely used in high and low voltage electrical appliances, industrial electric furnaces, generators and busbars, electrolytic smelting, and other fields. It is a key component in high current transmission scenarios. In practical applications, copper foil soft connections can effectively reduce contact resistance, improve overall system efficiency, and their flexibility enables them to adapt to complex installation environments, reducing failures caused by improper installation.
Copper foil soft flexible connection mainly adopts the following two welding techniques: Pressure welding process: Copper foil laminates are formed in one go by applying pressure and heating through molecular diffusion welding technology, without the need for additional solder. This process ensures a tight internal structure of the connector, free of pores and impurities, and guarantees excellent conductivity and mechanical strength. Brazing process: Silver based brazing material is used to weld copper foil laminates. Silver based brazing materials have excellent wetting and filling properties, which can form a strong bond between copper foils while maintaining good conductivity. If weld the copper foil into copper plate, usually use argon arc welding.
Materials and Parameters Material standard: T2(C11000), TU2( oxygen free copper,C10100) tape is used, and the contact surface can be tin plated or silver plated to enhance conductivity. These materials have extremely high purity and conductivity, ensuring the high performance of the connectors. Thickness range: 0.05mm to 0.5mm, specific parameters can be customized according to current carrying capacity and equipment requirements. Copper foil flexible connections of different thicknesses are suitable for different application scenarios and meet diverse engineering needs.
