Installation Method

Crimping (torque: 0.5 Nm to 3 Nm) or soldering; fork slots compatible with M3-M8 screws

Conductor Compatibility

Stranded or solid copper conductors (flexible/solid core); compatible with aluminum conductors (special plating available)

Technical Advantages

The rectangular fork design provides maximum surface contact with terminal blocks, reducing heat buildup and improving current flow by up to 20% compared to standard terminals. Precision-stamped from high-conductivity copper and available in multiple plating options, these terminals maintain optimal performance across temperature extremes from -40°C to +150°C. 

Independent testing verifies their mechanical durability, withstanding over 50,000 vibration cycles without loosening critical for automotive and heavy equipment applications. The tin-plated finish ensures long-term corrosion resistance while maintaining excellent solderability when required.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

What makes Rectangular Fork-Type Terminals suitable for high-vibration environments?

The cold-forged copper construction provides 400 MPa tensile strength, resisting deformation under mechanical stress. Precision-engineered fork slots maintain consistent clamping force even after 50,000+ vibration cycles (tested per IEC 60068-2-6). Tin-plated surfaces prevent fretting corrosion that typically loosens connections in heavy machinery or vehicles. 

How do these Rectangular Fork-Type Terminals compare to standard ring terminals for power distribution?

Rectangular fork designs enable 25% faster installation with tool-less screw access compared to ring terminals. The open-end construction accommodates thermal expansion in high-current applications (up to 100A). UL 486A-B certification ensures equivalent safety ratings to closed-ring alternatives. 

Are Rectangular Fork-Type Terminals compatible with both copper and aluminum conductors?

Standard versions are optimized for copper conductors from AWG 20-2, with tin plating to prevent galvanic corrosion. For aluminum wiring, nickel-plated variants are available to prevent oxidation at contact points. Material certifications include both ASTM B33 (copper) and IEC 61238-3 (aluminum compatibility) standards. 

What quality documentation supports bulk procurement decisions?

Full traceability includes mill certificates for copper purity (C11000) and plating thickness reports. Batch-specific UL certification files and RoHS compliance data are provided with every shipment. Third-party test reports validate current ratings and vibration resistance for engineering review. 

Can terminals be customized for specialized panel designs?

Fork widths from 4-10mm accommodate M3-M8 hardware, with custom bending angles available for tight spaces. Laser etching supports part numbering or compliance marking (UL/CE) for regulated industries. Prototype samples are produced within 10 working days for design validation.
