Copper tube terminal
Copper tube terminal lugs are commonly used cable connection accessories in electrical circuits, mainly used in scenarios such as power, distribution, and control cabinets.
Crimp terminals are electrical components that create reliable conductor-to-terminal connections through mechanical crimping—eliminating the need for soldering or heat. Widely used in power systems, automotive, industrial equipment, and building wiring, they offer high reliability, rapid installation, and cost efficiency.
1. Cold-Crimping Technology Principle
Heat-Free Processing:
Specialized tools (hydraulic pliers, manual crimpers) apply pressure to deform the terminal’s metal sleeve, forming an airtight bond with the conductor.
Metal Lattice Restructuring:
Pressure induces interpenetration of terminal/conductor lattices, reducing contact resistance and preventing oxidation.
2. Key Advantages
Lower contact resistance than soldered/screw connections
Excellent vibration resistance (ideal for automotive/mobile equipment)
Seconds per crimp—optimized for mass production
Preserves conductor insulation integrity
Safe for heat-sensitive environments
No solder fumes, compliant with RoHS/REACH

Butt splice terminals are used for intermediate docking/extension of two wires, such as in distribution box wiring, home appliance maintenance, car line modification, and home decoration wiring.
Compared to direct wire stripping and insertion, Vinyl-insulated crimp pin terminals can significantly improve the stability of wiring, especially in vibration environments or spring type terminal blocks, where poor contact, heating, and even sparking are less likely to occur.
Vinyl receptacle connectors are suitable for automotive wiring harnesses, electric vehicles, household appliances, low-voltage control circuits, and car modifications.
The wires can be quickly disassembled and connected without the need for welding or adhesive tape.
Vinyl-insulated Bullet Disconnects are made of PVC+Brass material with tin plating and are available in red, blue, and yellow colors.
Advantages of bullet crimp connectors: repeated disassembly and insertion, insulation safety, fast construction speed, no need for professional welding tools.
Vinyl-insulated male disconnector feature tin-plated brass construction and PVC insulation for secure, reliable wire connections in automotive and electrical applications.Male disconnect terminal features flat blade design with pre-insulated sheath and is commonly used as cold-pressed terminal for quick and reliable electrical connections.
Vinyl-insulated female disconnector is a quick plug and unplug cold pressed terminal block that does not require soldering. The wire is crimped at the end of the terminal using a cold press clamp, and then plugged into the matching male terminal for quick circuit disassembly and assembly, replacing tape wrapping and soldering.
Tin plated heavy duty ring terminal non insulated for 6–185mm² cables, rated 62A–395A, ideal for distribution boxes, high and low voltage control cabinets; Photovoltaic energy storage and inverter wiring; Main line of batteries for automobiles; High power lead connections for motors and transformers.
Vinyl insulated ring terminals (PVC/Nylon, copper). Sizes 0.5–6mm², 19–48A. Ideal for wiring, automotive, and industrial electrical connections.
SV series vinyl-insulated crimp fork terminals sizes 0.5–6mm², 19–48A. Suitable for distribution boxes, motors, industrial control equipment, and wire wiring.
