Joint insulation cover capable of changing color along with temperature

The invention relates to the field of insulating covers, in particular to a joint insulating cover capable of changing color along with temperature, which comprises an insulating cover body, a temperature sensing color changing module and a cable connector, the insulation cover body is a hollow shell, the temperature sensing and color changing module is used for sensing the temperature of the joint insulation cover and displaying corresponding colors, the temperature sensing and color changing module is fixedly connected with the insulation cover body, and the cable connector used for fixing a cable is arranged in the insulation cover body. According to the invention, through mutual cooperation of the insulating cover body, the temperature-sensing color-changing module and the cable connector, an effect of markedly displaying a fault part of the connector is realized; when the cable is overheated, heat can be transmitted to the insulation cover body through the cable connector, the temperature sensing color c
