Application and Introduction of Circular Cold Press Terminals

1. Main Application Scenarios

1.Electrical Equipment Wiring
●Used for wire connections in distribution boxes, switchgear, control cabinets, etc.
●Widely applied in industrial automation equipment, motors, transformers, and other terminal processing scenarios.
2.Building Wiring Projects
●For both low-voltage and high-voltage wiring in residential buildings (e.g., lighting, socket circuits).
●Used in HVAC systems, fire protection systems, and cable connections requiring quick termination.
3.Transportation Sector
●Electrical wiring in vehicles, ships, and rail transit systems where high-reliability connections are critical.
4.Instruments, Meters, and Household Appliances
●Miniature connections in precision instruments.
●Power cable fixation for household appliances (e.g., refrigerators, washing machines).

2. Structure and Materials

1.Design Features
●Main Material: Copper or aluminum alloy with tin plating/anti-oxidation coatings for enhanced conductivity and corrosion resistance.
●Cold-Pressing Chamber: Internal walls feature multiple teeth or wave patterns to ensure tight contact with conductors through cold pressing.
●Insulation Sleeve (optional): Provides additional protection in humid or dusty environments.
2.Technical Specifications
●Available in various sizes (0.5–35 mm² conductor cross-section) to accommodate different cable diameters.
●Supports screw-type, plug-and-play, or direct embedding into terminal blocks.

3. Core Advantages

1.Efficient Installation
●Requires no heating or welding; complete with a crimping tool for fast operation.
●Reduces labor costs and project duration through batch processing.
2.High Reliability
●Cold pressing ensures permanent molecular bonding between conductors and terminals, minimizing resistance and stable contact.
●Avoids oxidation and loose connections associated with traditional welding.
3.Strong Compatibility
●Suitable for copper, aluminum, and copper-alloy conductors, reducing galvanic corrosion risks.
●Universally compatible with standard circular cables.
4.Economic and Environmental Benefits
●Lead-free and eco-compliant with no thermal radiation.
●Long service life and low maintenance costs for long-term applications.

4. Key Usage Notes

1.Proper Sizing
●Select terminals based on cable diameter to avoid overloading or loosening.
2.Crimping Process
●Use certified crimping tools and follow manufacturer-recommended pressure values.
3.Environmental Protection
●Insulated versions recommended for wet/hazardous environments; apply protective sealant if needed.
4.Regular Maintenance
●Inspect connections in high-temperature or vibration-prone scenarios for signs of loosening or oxidation.
