Definitions

  • the present invention relates to small breakers and the like that are built into secondary battery packs and the like of electrical equipment.
  • the positive temperature coefficient thermistor is usually housed in a recess in the case.
  • the second case has the protrusion that protrudes from the inner bottom surface of the second housing portion toward the thermally responsive element, so that even when the breaker receives a large impact, the protrusion comes into contact with the thermally responsive element, causing the second case to suppress the movement of the thermally responsive element, and ultimately suppressing the movement of the positive temperature coefficient thermistor.
