Cable temperature detection device

The invention relates to the technical field of cable temperature detection, in particular to a cable temperature detection device which is characterized in that a spring is arranged on the inner surface of a base, a clamping plate is arranged at one end of the spring, a signal processing unit and a wireless transmission module are arranged on the surface of the upper base, a vertical plate is arranged on the side face of the upper base, and a guide rod is arranged at the bottom of the vertical plate; the surfaces of the guide rods are sleeved with second springs. The beneficial effects are that when a temperature detection device needs to be installed at a cable joint during use, the upper base is pulled firstly, then the base is matched with the upper base to sleeve a cable, then two groups of cables are connected, and finally the positioning plate is pulled down to enable the upper base to be matched with the base, so that the temperature detection device is installed at the cable joint. And the upper base
