Title:
TEMPERATURE ABNORMALITY DETECTING SENSOR
Document Type and Number:
Japanese Patent JP2013024718
Kind Code:
A
Abstract:

To make it possible, in a temperature abnormality detecting sensor, to individually find out in which of multiple temperature detecting elements any temperature abnormality has been detected and reduce the number of conductors laid between the positions of the multiple temperature detecting elements and the positions of an electric power supplying unit and of a detection signal input unit.

A temperature abnormality detecting sensor 1 comprises a plurality of temperature detectors 20 each of which includes: an anti-fuse circuit having an anti-fuse element 22 and a resistance element 23 electrically connected thereto in series, and a PTC thermistor 21 electrically connected to the anti-fuse circuit in parallel. The plurality of temperature detectors 20 are electrically connected in series. Further, the plurality of resistance elements 23 in the plurality of temperature detectors 20 differ from one another in resistance level and lower in resistance level than the lowest resistance level of each of the PTC thermistors 21.
