The invention discloses an installing structure for a socket and a plug. The installing structure comprises a socket body and a plug body, wherein the socket body comprises a bottom shell and an uppercover installed on the bottom shell; jacks are formed in the upper cover, a conducting seat is installed inside the bottom shell below each jack respectively, jacking mechanisms are arranged on two sides of each conducting seat respectively; the plug body comprises an upper base and a lower base, the upper base is rotatably connected onto the lower base, a first conducting ring and a second conducting ring are embedded in the upper end face of the lower base, an annular groove is formed in the lower end face of the upper base, a third conducting ring and a fourth conducting ring are embeddedin the inner bottom of the annular groove, and a limiting structure is arranged between the upper base and the lower base. After the structure is adopted, the phenomenon that the plug body is separated from the socket body can be avoided, and interference can be avoided from being generated among wires of adjacent plug bodies.
