The utility model discloses a plug-in type multipoint temperature measuring device for power cables, and relates to the cable temperature measurement technology field. The device comprises a temperature signal transmission line, one end of which is connected with a temperature measuring probe and the other end of which is connected with an earphone plug, wherein a temperature variation signal of the temperature measuring probe is transmitted to a temperature measurement instrument through the earphone plug. The plug-in type multipoint temperature measuring device has the advantages that only one temperature measurement instrument is needed to be installed, only a temperature sensor is installed at some position of paralleled power cables through the temperature signal transmission line, and therefore the temperature variation at the position of the paralleled power cables can be detected conveniently; and the plug-in type multipoint temperature measuring device is simple in structure, amount of temperature me
