IDC Connector
Top view is the IDC portion of the connector
Insulation Displacement Connector. [IDC] A connector that cuts through the insulation of a conductor to make contact with the wire, also called an Insulation Displacement Connector. A two-part connector for Flat Cable systems. Nominal spacing; 2.54mm.
Cables may be round, twisted or flat, but they must be flat as they terminated at the connector. Normally cables are flat ribbon cables that terminate at the connector, but some cables are twisted pairs or flat cables twisted into a round cable. In any case the cable needs to be flat as it enters the connector for termination. However the cable may contain discrete wires, not formed as a ribbon cable.
[another example IDC Connector view]
Insulation Displacement Connectors come in many different forms, most mount to a Printed Wiring Board [PWB]. But some do mount to another cable connector, as shown above. A D Sub-Miniature [D-Sub] connector is one of many connector styles that may contain a IDC terminating connector.
The DOD Specification Sheet MIL-DTL-24308/27D describes a IDC connector in a D-sub format.
