An electric connector includes a first pin, a second pin, a thermal conductor and a temperature sensor. The thermal conductor is disposed between the first pin and the second pin and simultaneously connected with the first pin and the second pin. The temperature sensor is embedded in the thermal conductor for sensing the temperature of the first pin and the second pin. Therefore, the thermal energy is rapidly and effectively transferred from the first pin and the second pin to the temperature sensor disposed in the thermal conductor, so that the temperature is precisely monitored and is rapidly reflected, and the safety of the electric connector is enhanced.
