Flexible Copper Foil Laminated Connectors - China Suppliers & Factory for Electrical Applications

The BGTBR(X) flexible copper foil laminated connector, made from high-quality C11000 copper foils, features ends that are joined through an advanced molecular diffusion welding process. This technique ensures a robust laminate, with pressed and heated contact areas that enhance conductivity. As a leading supplier in China, our factory specializes in producing laminated copper foil connectors tailored to specific designs. These connectors are renowned for their superior electrical conduction properties and find extensive applications in various sectors such as new-energy vehicles, switchgear industries, power plants, cathodic protection systems, bus ducts, transformers, vacuum circuit breakers, resistance welding engineering, electric locomotives, and furnaces. Most of our laminated copper foil connectors are custom-made according to detailed drawings, ensuring that they meet the diverse needs of our customers. Partner with us for reliable products that exemplify quality and performance.

    Product Advantages

    Compact & space-saving design
    Fits into small installation spaces; soft-state forming adapts to dynamic movements, vibrations, and misalignment.
    High welding quality
    Molecular diffusion welding eliminates re-welding, providing high joint strength and consistent conductivity.
    Easy installation
    Flexible section reduces terminal stress; no special tooling required.
    Various flexible part schemes
    Straight, offset, angled, or stepped configurations to match any equipment layout and movement state.
    Forming (soft-state) position customization
    The exact bending position of the flexible area can be tailored to meet unique spatial constraints.
    Finish options
    No-plating for cost-effective high conductivity; tin, nickel, or silver plating for corrosion resistance and soldering needs.

    Operating Conditions

    Temperature Range
    -40°C to +200°C
    Environment
    Suitable for indoor/outdoor use in clean, non-corrosive atmospheres; avoid direct chemical exposure.
    Vibration & Thermal Cycling
    Withstands high vibration (EVs, rail transit) and frequent thermal cycling.
    Current Capacity
    Depends on cross-sectional area & ambient temperature; engineering consultation recommended.

    Maintenance & Service Life

    Maintenance
    Periodic visual check for damage/corrosion; clean with dry air or soft brush.
    Service Life
    >20 years under normal conditions. Frequent flexing reduces life.
