Construction Instructions For An Insulating Puncture Connector

The piercing wire connector housing consists of an insulating shell that encloses the internal metal structure and isolates it from the outside environment. The shell material is typically chosen for its excellent UV resistance and aging resistance, making it suitable for outdoor environments.

A piercing blade is concealed within the shell. Made of a special alloy or tin-plated copper, the blade is positioned between the upper and lower insulator sections of the shell. Once tightened, it directly penetrates the cable's insulation layer and contacts the metal conductor, thus establishing an electrical connection.

A waterproof gasket surrounds the blade and, as the wire piercing connector housing closes, adheres to the surface of the cable insulation, sealing the piercing point and preventing moisture, humidity, or external contaminants from entering.

A torque bolt is used for the insulation piercing connector housing's tightening mechanism. During installation, the branch cable is inserted into the corresponding position, and the torque bolt is tightened using a socket wrench. As the bolt tightens, the upper and lower shell sections close, the piercing blade begins to pierce the insulation layer, the waterproof gasket presses shut, and the high-conductivity metal achieves contact between the conductors. When the torque reaches the set value, the nut will fall off, and piercing connector will reach the preset state.
