Plastic high-quality wire spiral terminal connectors are the "reliable hub" for circuit connections. They provide stable and safe connection solutions for strong and weak circuits with precision technology and high-quality materials. They are widely adapted to industrial control, building electrical, smart home and other scenarios.
In terms of core material, UL94 V0 grade flame retardant engineering plastic is used as the shell, and is molded by high-temperature injection molding, with excellent insulation performance, with a breakdown voltage of 25kV, far exceeding the industry standard 15kV, effectively avoiding the risks of short circuit and leakage.At the same time, the plastic material has outstanding high and low temperature resistance, and maintains its structure stability in an environment of -40℃ to 105℃, and will not crack or deformation due to alternate cold and heat, meeting the needs of extreme environments such as outdoors and industrial high temperature workshops.The internal conductive parts are made of high-purity electrolytic copper. After tin plating, the conductive performance is improved by 20%, and the contact resistance is only 0.5mΩ, ensuring that the current transmission loss is minimized.
Helical connection structure is the core advantage of the product.The terminal has a built-in precision threaded copper column and is paired with high-strength cross-groove screws. A uniform pressure is generated during tightening, so that the wires and the copper column are closely connected. Even in vibrating environments (such as machine tools and automotive wiring harnesses), the probability of loose connections is less than 0.1%.The wiring range covers multiple or single-strand wires of 0.5-6mm², and can be quickly wired without stripping tools. The single-terminal wiring time is reduced to 30 seconds, and the efficiency is twice that of traditional crimp terminals.In addition, the spiral structure supports repeated wiring and can be repeatedly disassembled and used more than 50 times to meet the needs of line maintenance and renovation.
Detailed design takes into account both safety and convenience.The surface of the shell is treated with anti-slip texture, which is easy to install and disassemble with bare hands and avoid damage caused by tool slippage.Each terminal is equipped with an independent marking slot, which can be inserted into label paper to distinguish between live wires, neutral wires and ground wires to reduce wiring errors.The terminal spacing strictly follows the 3.5mm safety standard, prevents adjacent terminals from short circuit, and supports superimposed and combined installation. It is spliced into terminal strips through a snap structure, saving installation space in the distribution box.A wire fixing hole is provided at the rear, which can fix the wires through cable ties to prevent the wire from being pulled by force and causing the terminal to loosen.
Adaptable scenarios cover multiple fields of needs.In building electrical, it is suitable for branch connections of lighting circuits and socket junction boxes; in the field of industrial automation, it can be used as signal terminals and power terminals of PLC control cabinets and inverters; in smart home systems, it can meet the weak-current connection needs of sensors and controllers; in new energy equipment, it is suitable for low-voltage line connections that are suitable for photovoltaic inverters and energy storage batteries.The product has passed the triple certification of CE, UL, and CCC, complies with the EU RoHS environmental protection standards, and does not contain harmful substances such as lead and cadmium. It can be used in scenarios such as food processing and medical equipment that require strict environmental protection.
This high-quality plastic wire spiral terminal connector, with "safety, reliable, efficient and convenient" as the core, uses precision technology to solve the pain points of loose connections and cumbersome wiring, and provides stable connection guarantees for various circuit systems. It is an ideal choice to improve line safety and construction efficiency
