Flexible Laminated Copper Connectors with Nickel or Silver Foils - China Suppliers & Factory for New Energy Vehicles

Our laminated copper foil connectors are available upon request with protective nickel or silver foils on both the upper and lower laminations. This enhancement provides superior resistance to oxidation and corrosion, while also eliminating the risk of residual plating solution entrapment, a common issue in plated connectors. Designed for compactness and easy installation in tight spaces, our connectors feature soft-state forming and multiple flexible configurations (straight, offset, angled, stepped) to accommodate a variety of installation environments and movement conditions, such as vibration and thermal expansion. With diffusion-welded ends ensuring high weld quality, there is no need for re-welding. These connectors are ideal for applications in new-energy vehicles, switchgear, transformers, and bus ducts. As a reputable factory in China, we pride ourselves on supplying high-quality components to meet diverse industry needs.

    Product Advantages

    Superior corrosion & oxidation resistance – Nickel or silver cover foils protect the copper core without any trapped plating solution.

    No re-welding & high weld quality – Molecular diffusion welding on both ends creates a strong, low-resistance joint.

    Compact & space-saving – Soft-state forming fits into small installation spaces; various flexible part designs (straight, offset, angled, stepped) match different equipment layouts and movement states (vibration, thermal expansion, misalignment).

    Easy installation – The flexible section reduces terminal stress; no special tools required.

    Forming (soft-state) position customizable – The exact bending location of the flexible area can be tailored to unique spatial constraints.

    Operating Conditions

    Temperature range: -40°C to +200°C.

    Suitable for indoor/outdoor use in clean, non-corrosive atmospheres; avoid direct chemical exposure.

    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.

    After-Sales Service

    Free technical support: engineering consultation, drawings...

    Custom orders: lead time & quality report provided before shipment

    Frequently Asked Questions (FAQ)

    What materials are used in flexible laminated copper connectors?
    The core is made of high-purity C11000 copper foil (≥99.95% Cu), laminated with nickel foil or silver foil cover layers (thickness options: 0.05mm, 0.10mm, 0.20mm) to ensure superior corrosion and oxidation resistance.
    What is the operating temperature and lifespan of these connectors?
    They operate reliably in temperatures ranging from -40°C to +200°C and offer a service life exceeding 20 years under normal operating conditions.
    Can connector shapes and flexible areas be customized?
    Yes, soft-state forming positions and connector shapes (straight, offset, angled, stepped) can be fully customized according to your equipment layout and spatial constraints.
    Are these laminated connectors suitable for high-vibration environments?
    Yes, molecular diffusion welding combined with a flexible laminated body makes them ideal for absorbing vibration and thermal expansion in electric vehicles (EVs) and rail transit systems.
    What details are required to request a quote or place an order?
    Please provide overall dimensions (L × W × T), connector shape, hole specifications, single foil thickness, plating requirements, rated current/cross-sectional area, quantity, and 2D drawings (PDF/DWG).
