CORE WIRE CONTACT DETECTION DEVICE

摘要

Provided is a core wire contact detection device which detects contact between a strip blade and a core wire when a sheath of an electric wire is stripped by the strip blade. The core wire contact detection device includes a vibration detection unit capable of detecting a vibration in a frequency range including a vibration frequency generated due to the contact between the core wire and the strip blade, and a contact state determination processing unit which determines that the strip blade and the core wire are in contact with each other when an amplitude of the detected vibration exceeds a predetermined threshold value.
