10 Pcs 4 Pin Wire Connectors 22-20 AWG No Strip Insulation Piercing Clips

What is this?Quick connect terminal blocks are solderless, insulation-displacement electrical connectors designed for fast, tool-free wire splicing in low-voltage systems. They feature a patented blade technology that pierces wire insulation to create instant, secure connections without stripping wires. For 22-20 AWG wires, these connectors come in 1P to 6P configurations (1 to 6 poles) for joining multiple wires in automotive, home electronics, LED lighting, and security systems.What will I get?PIN Number: 4 Pin;Color: Transparent;Rated voltage: 300VMaximum current: 1.5-4.5AMaximum temperature resistance: 80°CSuitable wire cross section: 0.35-0.5 mm² AWG22-20Contact sheet material: nickel-plated copperShell Material: Plastic;Size(L*W*H): 23x13.9x8.3mm/0.91x0.55x0.33inch;In the package of: 10 Pcs x Solder-free Terminal Blocks;Are there any advantages of the product?The product adopts puncture connection, which does not damage the original wire protection layer, completely avoids stripping, and the conductor is not exposed. The cross-sectional area of the wire is larger than its own cross-sectional area, which reduces the current load. The conductor is connected 1 to 1, and the internal plastic body is isolated to prevent short circuits. It improves wiring standardization and facilitates later maintenance and inspection.How to use it?Before use, make sure the product cover is not pressed down; align the wires to be connected and insert them into the connector slots; press the connector firmly until you hear a click - the blades will pierce the insulation and clamp the wires; check for power.What should I notice?Always disconnect power sources before working on electrical systems.
