Piercing Connector

An instrument used to branch and connect cables is a piercing clamp. It has a piercing blade inside and a reinforced shell outside. To connect or branch cables, simply put the cable into the waterproof terminal cap sleeve and tighten the torque nut on the clamp with a socket wrench. The sealing ring presses around the cable's punctured location while the piercing blade penetrates the insulation and makes contact with the conductors during the tightening process. The main line and branch line are connected, the torque reaches the predetermined value, the nut torque mechanism disengages, and the electrical effect and waterproof performance meet the standard's requirements.

General Information of Insulation Cable Piercing Electrical Connector (IPC)

  • Piercing connector, simple installation, need not strip the cable coat.

  • Moment nut, piercing pressure is constant, keep good electric connection and make no damage to lead.

  • Self-seam frame, wetproof, waterproof, and anti-corrosion, extend the using life of insulated lead and connector.

  • Adopted special connecting tablet, apply to joint of Cu(Al) and Cu(Al) or Cu and Al.

  • Small electric connecting resistance, connecting resistance less than 2.5 times of the resistance of branch conductor with the same accordance with the standard DL/T765.1-2001.

  • Special insulated case body, resistance to illumination and environmental aging, the insulation strength can up to 12kV.

  • Arc surface design, apply to connection with the same (different) diameter, wide connection scope (0.75mm2-400mm2/

Performance Testing of Insulation Cable Piercing Electrical Connector (IPC)

  • Mechanical performance: the grip force of the wire clamp is 1/10 bigger than the break force of the lead, It comply with GB2314-1997.

  • Temperature rise performance: under the condition of big current, the temperature rise of connector is less than that of connection lead.

  • Heat circle performance: conforms to GB/T2317.3-2000, the heat circle trial standard for electric fitting.

  • Waterproof insulation performance: conforms to the relevant testing requirements in Part 2 of GB/T13140.4-1998.

  • Resistance to corrosion performance: under the condition of SO2 and salt fog, it can do three times of fourteen days circle testing.

  • Environmental aging performance: under the circumstance of ultraviolet, radiation, dry and moist, expose it with change of temperature and heat impulse for six weeks.

  • Fire-proof performance: insulation material of the connector withstands glowing filament test. Conform to the requirements in Chapter 4-10 of GB/T5169.4.
