The invention discloses a socket. The socket comprises a socket body, wherein the socket body comprises a bottom shell and an upper cover mounted on the bottom shell; jacks for conducting plates on aplug body to penetrate through are formed in the upper cover; a conducting seat is mounted inside the bottom shell below each jack respectively; four supporting columns are arranged inside the bottomshell below each conducting seat respectively; the outer walls of two sides of each conducting seat are connected with two of the supporting columns in a clamping manner; and a jacking mechanism for pushing conducting spring plates on each conducting seat so that the conducting spring plates cling to the conducting plates after the conducting plates are inserted into the conducting seat is arranged on two sides of each conducting seat respectively. After the structure is adopted, the phenomenon that a plug body is separated from a socket body can be avoided.
