Application Of Specialized Contact Blades In Piercing Wire Clamps

Electrical connection systems place stringent requirements on the reliability of conductor contacts. insulation piercing connector During installation, it is necessary to penetrate the insulation layer and form a stable electrical connection with the conductor. This process places special demands on the material and geometry of the blade. Traditional blades are prone to producing burrs or damaging the conductor during penetration, affecting the contact area and conductivity.

Specialized contact blades typically use high-strength copper alloys or tin-plated copper, materials with excellent conductivity and oxidation resistance. The blade's sharpness angle is precisely calculated to smoothly cut through the insulation sheath without excessively cutting aluminum or copper conductors. Surface treatment processes reduce contact resistance and minimize heat generation during long-term operation.

The branch connection scenario of the power distribution network requires that piercing connector can be installed without interrupting the main power supply. The blade's penetration depth and contact pressure need to be balanced—ensuring sufficient contact area while preventing damage to the conductor cross-section. This design allows installers to quickly complete tapping during live work, improving project efficiency while maintaining the electrical stability of the connection point.
