What is the IDC connector ?
IDC connector is Insulation-displacement connectors.
Insulation-displacement connectors
Insulation-displacement connectors were developed to provide a fast reliable means of terminating multiway cables. Like crimping, the connection is made (Figure 1) by pressure contact between terminal and conductor to break down intervening oxide (as well as ‘displacing’ the insulation around the conductor), using controlled methods of pressing together connector and cable.
Sometimes special jigs and presses are needed; in other cases the connectors are self-jigging (Figure 2).
