The invention is suitable for the technical field of rail transit, and particularly relates to a wiring terminal overheating early warning device which comprises a thermoelectric power generation module, an electromagnetic conversion module and a switching display module; the thermoelectric power generation module is arranged on an insulator of a wiring terminal and is used for generating voltage through thermoelectric power generation when the temperature of the wiring terminal exceeds a first preset temperature; the electromagnetic conversion module is used for converting voltage generated by thermoelectric power generation into magnetic force and generating displacement based on the magnetic force; the switching display module is used for switching the state of the switching display module on the basis of the displacement so as to display first information; the first information is used for indicating that the temperature of the wiring terminal exceeds the preset temperature. According to the device, the p
