The present invention discloses a creepage protection socket capable of life finish detecting automatically and display detecting result. Wherein, a pair of elastic metal slices is connected with power supply output end on the socket circuit board, a pair of moving contact is set on metal slice. Two pairs of static contacts are set on power supply output conductor which are correspond uprightly respectively to moving contacts of metal slice of power supply and elastic metal slice to form two sets four pairs switch. Life stop detecting circuit is set on circuit board, when the socket connects power supply, the creepage protection capability is detected automatically, if the socket life is stop, stop replacement button replacing, the load end of socket and power supply output hole have no current, and awoke user to change creepage protection socket in time by replacement indicator light. The present invention has total function, good safety, can ensure the safety of user and electric appliance.
