QUICK WIRING CONNECTOR:D-type fast solder-free wire connector, new inter-plug design, no need to strip the wire. The electrical connectors do not distinguish between male and female, and they can be docked with each other arbitrarily, and can be quickly connected by simply inserting and squeezing the wires. SAFE AND RELIABLE:The low-voltage cable connector is waterproof and dustproof, which can avoid the risk of electric shock. The pluggable design allows users to disconnect the power supply when maintaining or replacing equipment, without worrying about short circuits and leakage caused by irregular connections. HIGH-QUALITY MATERIAL:The terminal block housing is made of Polycarbonate material, and the inner conductor is made of high-precision pure copper material, which is waterproof, dustproof, heat-resistant and durable. The one-to-one connection of each wire standardizes the wiring for easy maintenance and use. REUSABLE:Quick terminal blocks are reusable, saving cost. Each terminal has an independent shrapnel, different wires are managed separately, and different wire diameters can be safely connected. WIDE APPLICATIONS:The wire connector is suitable for 18-22AWG wires, compatible with all kinds of single-core hard wires, multi-core wires, and flexible wires, suitable for various application fields. Ideal for most vehicles, audio, video, speakers, LED light bar mounts and other electrical equipment and more.
