Features: brand new and high quality brand new and high quality Quickly operate wiring, save for time and effort, simple and fast, reduce cost, for all kinds of single-core hard wires, multi-core wires, and flexible wires. No peeling, no exposed conductors, excellent current-carrying, and no safety hazards. The piercing connection does not damage the protective layer of the original wire, and the cross-sectional area of the wire is larger than its own cross-sectional area, reducing the current load. It adopts the structure of multiple punctured wire insulation and clamping and pressing to ensure that the connection is not easy to fall off, strengthen the safety, and avoid the occurrence of arc. Use conductors for 2 to 2 butt connection, and use internal plastic isolation to prevent short circuits. Improve the standardization of wiring to facilitate later maintenance.
