Tinned Copper Flexible Connector

Tinned Copper Flexible Connector

tinned copper flexible connector is a high-reliability electrical connection component, crafted from tinned copper strands (braided structure) and precision-pressed tinned terminals. It combines excellent conductivity, flexibility, and corrosion resistance, designed to compensate for mechanical displacement, absorb vibration, and ensure stable current transmission in demanding electrical systems.

Core Performance

Conductivity: DC resistance ≤ 0.0012Ω/m (for 50mm² cross-section), ensuring low power loss and minimal heat generation.
• Flexibility: Bend radius ≥ 2× the connector width, enabling installation in narrow spaces and absorbing thermal expansion/contraction of equipment.
• Corrosion Resistance: Tin-plated surface (thickness ≥ 3μm) provides long-term protection against oxidation, salt spray, and humidity (passes 480h salt spray test per ASTM B117).
• Mechanical Strength: Tensile strength ≥ 150N (for 30mm² model), with crimped terminals ensuring pull-out force ≥ 200N (no loosening under vibration).
• Temperature Resistance: Operating temperature range: -40°C to 120°C, suitable for both low-temperature and moderate-heat environments.

Application Fields

Electrical Equipment: Busbar connections in switchgear, transformer low-voltage leads, generator terminals.
• Industrial Machinery: Welding equipment, electroplating power supplies, battery pack connections (EV, energy storage systems).
• Renewable Energy: Solar inverter terminals, wind turbine electrical systems.
• Transportation: Electric vehicle (EV) battery modules, railway locomotive electrical connections.
