Insulation-displacement connector

An insulation-displacement connector (IDC), insulation-displacement technology/termination (IDT) or insulation-piercing connector is an electrical connector designed to be connected to the conductor(s) of an insulated wire or cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the wire of insulation before connecting. When properly made, the connector blade cold-welds to the wire, making a highly reliable gas-tight connection.[1][2]

Modern IDC technology developed after and was influenced by research on wire-wrap and crimp connector technology originally pioneered by Western ElectricBell Telephone Labs, and others.[3] Although originally designed to connect only solid (single-stranded) conductors, IDC technology was eventually extended to multiple-stranded wire as well.

Initially, insulation displacement connections were seen only in extra-low voltage applications, such as telecommunicationsnetworking and signal connections between parts of an electronic or computer system. However, they are now also used in some domestic and industrial low voltage (power) applications.[4][5] The benefits claimed for their use in these applications include up to 50 percent faster installation, due to the reduction in the stripping, twisting and screwing down processes.
