An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process. The IDC forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the cable.
