    Key Advantages

    Excellent mechanical properties: compaction creates a solid end - The solderless pressing process compresses the ferrule onto the copper stranded wire without altering its overall dimensions. This creates a dense, solid end that prevents strand loosening, enhances pull-out strength, and ensures reliable termination even under high mechanical stress.

    Reduced thermal resistance: The flexible stranded structure combined with ≥99.95% pure copper provides excellent heat dissipation, significantly lowering temperature rise under high current or short-circuit conditions, thus improving system reliability.

    Ends can be drilled, milled, machined and profiled to meet mechanical demands: Our terminals are not limited to standard holes. We can drill, mill, profile, or fully machine the pressed or welded ends to create custom slot patterns, threaded holes, or complex mounting shapes, eliminating the need for additional adapters.

    Superior vibration & fatigue resistance: The fine multi-wire stranded design absorbs mechanical stress without work hardening, making it ideal for dynamic applications like traction motors or railway connections.

    Low and stable contact resistance: Solderless pressed ferrules ensure a large, uniform contact interface that remains stable over thermal cycles.

    Operating Conditions

    • Temperature range: -40°C to +200°C (depends on plating)

    • Suitable for indoor & protected outdoor use

    • Excellent for high-vibration & dynamic applications

    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.

    Replace if: ferrule cracks, overheating discoloration, or broken braid strands.

    After-Sales Service

    Free technical support: engineering consultation, drawings...

    Custom orders: lead time & quality report provided before shipment

    Frequently Asked Questions (FAQ)

    What raw materials and purity are used for these flexible copper connectors?
    Our connectors are manufactured using high-grade annealed Cu-ETP wires (C11000) with a guaranteed copper content of ≥ 99.95%, ensuring exceptional electrical conductivity and minimal thermal resistance.
    What surface plating options are available for the terminals?
    We offer bare copper as well as tin plating, nickel plating, and silver plating to suit diverse environmental conditions and conductivity requirements.
    Can the ferrule terminal ends be customized with special hole patterns or machining?
    Yes. The ends can be drilled, milled, profiled, or fully machined to produce custom mounting patterns, slots, or threaded holes according to your engineering drawings without needing additional adapters.
    What is the operating temperature range and typical service life?
    The connectors operate reliably in temperatures ranging from -40°C to +200°C (depending on the plating selected). Under normal conditions, they provide an expected service life exceeding 20 years.
    What information is needed to place a custom order?
    Please provide the cross-sectional area (1.5mm²–6000mm²), total length (L), ferrule & hole type, hole diameter (d), and single wire diameter (default standard is 0.15mm).
    How do solderless pressed ferrules improve connector performance in high-vibration applications?
    The solderless pressing creates a dense, solid end termination that prevents strand loosening, delivers low contact resistance, and provides high fatigue resistance against vibration without work hardening.
