  • Contact failure detection system
    Patent number: 11088404
    Abstract: A temperature sensor detects a temperature at a contact between a live part of connector for a first circuit device and a live part of a connector a for second circuit device. A controller determines the occurrence of a contact failure between the live parts if a difference between an amount of change in temperature detected by the temperature sensor per predetermined time and an amount of change in ambient temperature per predetermined time is greater than a set value.
    Type: Grant

  • CONTACT FAILURE DETECTION SYSTEM
    Publication number: 20190319317
    Abstract: A temperature sensor (Tp, Tm) detects a temperature at a contact between a live part of connector (11) for a first circuit device (10) and a live part of a connector (21) a for second circuit device (20). A controller (24) determines the occurrence of a contact failure between the live parts if a difference between an amount of change in temperature detected by the temperature sensor (Tp, Tm) per predetermined time and an amount of change in ambient temperature per predetermined time is greater than a set value.
