The embodiment of the invention provides a quick charging gun charging socket temperature sensing detection circuit and a quick charging gun charging socket, and belongs to the field of vehicle charging. The detection circuit comprises a temperature sensing resistor to be detected, and one end of the temperature sensing resistor to be detected is grounded; one end of the pull-up resistor is connected with the other end of the temperature sensing resistor to be measured, and the other end of the pull-up resistor is connected with a pull-up power supply; the controllable switching power supply module is connected between the pull-up resistor and a pull-up power supply, and can close or open a circuit where the controllable switching power supply module is located according to whether the vehicle is charged or not; an ADC pull-up power supply, wherein the ADC pull-up power supply is connected to one end of the pull-up resistor; and the ADC acquisition module is connected between one end of the pull-up resistor and the pull-up power supply. According to the detection circuit, the influence of offset between the pull-up power supply and the power supply can be avoided, and the resistance value of the temperature sensing resistor of the charging socket of the charging gun can be obtained.
