Features: Make of strong plastic, to ensure the stability and safety of the connection. The piercing terminal penetrates the insulation layer directly into conductors, eliminating the need for stripping and significantly reducing the wiring time. Use elastic metal sheet or spring structure, which can fix the cable with a single press and is highly efficient to operate. Pin design to maintain stable conductivity even in vibrating conditions, reducing the risk of poor contact. Adaptive clamping structure support cables of different thicknesses, such as 1.5-4mm²(main line),0.75-2.5mm²(branch line).
