Product Advantages
Economical solution for low current applications
For control circuits, auxiliary grounding, and signal bonding where current ratings are moderate, this lug‑type connector offers reliable performance at a lower cost compared to heavy-duty compression terminals.
High flexibility & vibration absorption
The stranded fine wires dampen mechanical stress, prevent fatigue failure at rigid connection points, and compensate for thermal expansion, making the connector ideal for dynamic or space-limited installations.
Wide compatibility
Stock sizes (1.5mm² - 500mm²) and common lug types (ring, fork, flag, rectangular) meet most industrial needs, with full customization available for non-standard requirements.
Multiple plating options
Choose from bare, tin, nickel, or silver plating to match your specific temperature range and corrosion environment.
Operating Conditions
Temperature range: -40°C to +200°C (depends on plating)
Environment: Suitable for indoor & protected outdoor use
Application: 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 occur.
After-Sales Service
Free technical support: Engineering consultation, drawings, and dimension evaluation.
Custom orders: Lead time & quality inspection report provided before shipment.
Ordering Checklist

Frequently Asked Questions (FAQ)
1. What material is used for these flexible copper connectors?
They are manufactured using high-purity annealed Cu-ETP wires (C11000) with a copper content of ≥ 99.95%, ensuring exceptional electrical conductivity and flexibility.
2. What surface plating finishes are available?
We offer bare copper, tin plating, nickel plating, and silver plating to suit diverse working temperatures and corrosion resistance requirements.
3. What is the standard single wire diameter and cross-sectional range?
The cross-sectional area ranges from 1.5mm² to 500mm². The standard single wire diameter is 0.15mm, with optional sizes available from 0.05mm (AWG 44) up to 0.254mm (AWG 30).
4. What is the expected service life of these connectors?
Under normal operating conditions, the expected service life is over 20 years. However, frequent and extreme dynamic flexing may reduce this lifespan.
5. What information should be specified when placing a custom order?
Please specify the cross-sectional area, total length between holes (L), lug/ferrule type, hole diameter (d), and single wire diameter (default is 0.15mm).
6. What signs indicate that a copper connector should be replaced?
The connector should be replaced immediately if you observe cracked ferrules/lugs, discoloration caused by overheating, or broken braided wire strands.
