The present invention discloses a leakage protection socket with automatic life-span stop detection and detection result displaying functions, which is characterized in that: four active contacts are arranged on a power input metal sheet, a power output conductor and a power output metal sheet are provided with four static contacts together. The four pairs of active and static contacts form four pairs of power switches which are parallelly arranged. The leakage protection socket is further provided with a trip gear which can enable four pairs of active and static contacts to contact/break off. A life-span stop detection circuit is further arranged on the circuit board to detect the leakage protection function automatically when the socket is inserted into power source, and then stop the reset of a resetting button if finding out that the life-span of the socket is stopped so that the load end and the power output hole of the socket have no power output and user to change the leakage protection socket through displaying the life-span stop by a fault state indication lamp. The present invention is of full functions and good safety and can indeed guarantee human body safety and appliance safety for users.
