Analysis Of The Structural Design Concept Of Puncture Clamp

In power and distribution systems, cable electrical piercing connector penetrates the insulation layer directly through an internal metal piercing blade while maintaining the integrity of the conductor's outer insulation. Its upper and lower housings are made of engineering plastic and are secured with bolts. The housings house the main and branch lines, and insulation connector contains clamps and concealed piercing blades. The blades are made of a high-conductivity alloy to ensure good contact with the conductor. The housings contain insulating sleeves and sealing gaskets, and the blades insulation piercing are covered by an insulating sheath, meeting the requirements for moisture resistance, corrosion resistance, and UV aging resistance.

During installation, the main and branch lines are placed into their corresponding clamps, and then the bolts are tightened. Once the blade pierces the insulation layer and contacts the conductor, the clamp closes. A torque nut is often used in the design; its set torque causes the blade to complete the piercing connection insulation piercing clamp and disconnect the protective nut, indicating installation completion. The entire process does not require stripping the insulation and does not alter the original cable structure.
