insulation displacement connection (IDC)

The insulation displacement connection (IDC) is a practical, solderless technique for connecting conductors in sockets. With this connection technique, the conductors do not have to be pre-treated and stripped, but are placed with their insulation on the IDC and pressed into the terminal with a special tool.

Since the insulation displacement connector has sharp edges, the insulation is cut by the insulation displacement connector when the conductor is pressed in and the wire is connected to the connector.

The advantages are that the wire does not have to be stripped, oxidation is still prevented by the insulation, and the wire values are not changed by removing the insulation. This type of lay-up is not suitable for stranded conductors, but only for cores such as those used in the floor area.

Newer techniques dispense with the special tool and use the closing of a specially designed cover to press the cores into the insulation displacement terminals. Insulation displacement connections are specified in IEC 60352-3 and IEC 60352-4 and the corresponding DIN regulations.
