The invention concerns a production line consisting of an automated system for the realization of the industrial wiring of IDC connectors. A first station includes a selection guide accommodating a series of IDC connectors, and a series of pushers for shifting the series of connectors to a paired closure guide for closing the connectors of a second station. The closure guide has a series of mobile spacer partitions interposed between each of several seats, configured to release the connectors by moving said partitions as soon as the connectors are crimped onto cable wires. A third crimping station comprising a series of punches spaced apart from each other at a pre-set distance on a mobile support, which can move to pull each connector the pre-set distance until it brings an adjacent punch into position at an adjacent connector to be crimped.
