AI summary

A method for cable wire insertion verification includes, at an insertion verification system, receiving a vibration signal from a vibration sensor. The vibration signal represents vibration caused by insertion of a cable wire into a cable cavity of a cable connector housing. The vibration signal is input to an insertion verification model trained to evaluate whether input vibration signals are consistent with correct cable wire insertion. The insertion verification model outputs an indication that the vibration signal is consistent with correct insertion of the cable wire into the cable cavity.
