Abstract:
1. A safety plug socket, comprising: an outer housing, provided with pairs of socket holes to enable insertion of plug terminals, a cylindrical spring base extends from a bottom portion of the outer housing corresponding to a middle position of the pair of socket holes, and a lower portion of a spring is retained within the cylindrical spring base; an electric wire enables effecting the supply of power, and the electric wire extends into the outer housing; at least one pair of conductive clips, disposed within the outer housing corresponding to the pairs of socket holes, each of the conductive clips is disposed in one of the socket holes, and provided with folded strips extending to a bottom portion of the outer housing; at least one sliding insulating base, a center of the sliding insulating base formed with a cylinder extending upwardly; a bottom surface of the horizontal plate is provided with a pair of contact conducting strips corresponding to the folded strips of the pairs of conductive clips; an inside diameter of the cylinder is greater than an outer diameter of the cylindrical spring base and retains an upper portion of the spring, the pair of contact conducting strips maintain separation with the folded strips in normal position; and at least one pair of power contacts, disposed in a separated configuration within the outer housing and conductively connected with the electric wire, the power contacts are respectively conductively connected to the pair of contact conducting strips on the bottom surface of the horizontal plate of the sliding insulating base; when the terminals of a plug are inserted into the socket holes of the outer housing, the sliding insulating base being pressed down that causes the contact conducting strips to make conductive contact with the folded strips of the pair of conductive clips, and enabling the plug to effect the supply of power; wherein a pair of first contact points extend from bottom surfaces of the pair of contact conducting strips, and a pair of second contact points extend from upper surface of the folded strips, when the sliding insulating base is dressed down, the first contact points make contact with the second contact points.
