Model And Meaning
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 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.
- Durability: 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
What material and purity are used for copper foil laminated connectors?
Our connectors are manufactured using premium C11000 copper foil with a copper purity content of ≥ 99.95%, ensuring exceptional electrical conductivity and minimal thermal resistance.
What welding technology is utilized for the connector terminals?
We utilize advanced molecular diffusion welding technology. This bonds the laminated copper foils together at a molecular level without requiring solder or filler metals, eliminating re-welding issues and providing superior joint strength and conductivity.
What surface plating options are available?
We offer bare (no plating) copper for standard high-conductivity needs, as well as tin plating, nickel plating, and silver plating for enhanced corrosion resistance, oxidation protection, and specific soldering requirements.
What is the operating temperature range and expected service life?
The operating temperature range is -40°C to +200°C. Under normal working conditions in non-corrosive environments, the expected service life exceeds 20 years.
Can these flexible copper connectors be custom-formed for specific spaces?
Yes, we provide extensive customization for connector configurations including straight, offset, angled, and stepped shapes. The soft-state forming position can be tailored exactly to accommodate tight spaces, dynamic movements, and equipment vibration.
What technical information is required when requesting a quotation?
Please provide overall dimensions (L × W × T), connector shape/flexible area configuration, hole diameter/pattern, single foil thickness, plating requirement, target current capacity, and 2D CAD drawings (PDF/DWG) if available.
