Braided Tin Coated Copper Flexible Connectors
Braided Tin Coated Copper Flexible Connectors are conductive flexible connection components made of multiple strands of high-purity copper wires precision braided and then hot-dip tin-plated. This product is widely used in new energy vehicles, rail transportation, industrial automation, and power equipment. Its core function lies in achieving a balance between high flexibility and excellent conductivity through its braided structure, providing reliable dynamic connections, stress compensation, and environmental protection for electrical systems.

Product Introduction
This Braided Tin Coated Copper Flexible Connectors is a flexible conductive connection component specifically developed for the new energy and power electronics fields. It uses a high-purity T2 copper substrate with a uniform tin plating layer and is manufactured through precision braiding, forming, and welding processes. The product features low impedance, high flexibility, and long lifespan, perfectly adapting to the dynamic connection, shock absorption, and temperature difference compensation needs of high-power equipment, energy storage systems, photovoltaic inverters, charging piles, high and low voltage electrical cabinets, and other scenarios.
performance advantages
Vibration Fatigue Resistance
The braided structure eliminates single stress concentration points, with each copper wire independently bearing and sharing strain. Vibration table testing verifies that under 10Hz~2000Hz sweep vibration conditions, the product lifespan meets the requirements for new energy vehicles and rail transit applications.
Temperature Cycling Resistance
The thermal expansion coefficients of the tin plating layer and the copper substrate are 23ppm/℃ and 17ppm/℃, respectively, forming reversible interfacial stress during temperature cycling from -40℃ to 125℃. After 1000 cycles, the contact resistance change rate is controlled within ±15% of the initial value.
Salt Spray Corrosion Resistance
The tin plating layer can withstand more than 96 hours of neutral salt spray testing without the appearance of red rust, meeting the corrosion resistance requirements for automotive and outdoor applications.
Processing and customization process
Technical Documentation Submission: The customer provides Flat Copper Braided Flexible Connectors PDF/CAD/3D drawings, clearly indicating rated current carrying capacity, dimensions, installation interfaces, plating thickness, purchase quantity, and special operating conditions. Our engineering team will receive, archive, and verify the technical details.
Process Review and Quotation: We conduct a specialized process feasibility assessment, accurately calculating costs and delivery cycles based on braiding density, welding processes, and processing complexity, and issue a formal quotation and supporting technical solutions.
Sample Order and Mold Prepayment: After both parties confirm the quotation and technical solutions without objection, the customer places a Braided Copper Flexible Connectors sample order and pays a 50% prepayment for mold development, which we will file and archive.
Sample Trial Production and Testing: We initiate specialized mold processing, wire preparation, and sample mass production, strictly controlling process parameters throughout. After the sample is completed and passes full quality inspection, we will provide 1-20 samples free of charge to the customer to verify electrical performance, mechanical compatibility, and operating condition simulation.
Mold Final Payment and Design Finalization: After the customer confirms the sample's quality, they pay the remaining 50% of the mold fee, completing the final design of the mold and Flexible Copper Braided Electrical Connectors, and locking in technical parameters and process standards.
Bulk Orders and Production Initiation: The customer places a formal bulk order and pays a 30% production prepayment. Our company verifies order information, raw material inventory, and production capacity, finalizes the delivery date, initiates large-scale mass production, and implements full-process quality control.
Final Payment and Delivery: After all Braided Tin Coated Copper Flexible Connectors are completed and pass inspection, our company issues a complete packaging list and quality inspection report. The customer pays the remaining 70% of the balance, and our company ships the goods through the designated logistics channel, tracking the logistics throughout the process to ensure the goods arrive intact.
