Abstract

The utility model discloses a socket adapter comprising an insulating essential body, a first terminal, and a second terminal which are arranged inside the insulating essential body. An inserting hole is arranged on the front wall of the insulating essential body. A floor of the inserting hole is formed by the blind end of the inserting hole and a through-hole is opened on the floor. A supporting section is formed by the floor of the inserting hole protruding forward. The central pin of the first terminal drills through the through-hole and stays in the inserting hole. The front end of the plug adapter which is connected with the socket adapter of the utility model subsides to form a slant section. A central pin hole is arranged on the floor of the slant section. The slant section and the supporting section of the socket adapter are inserted with each other. The central pin is inserted into the central pin hole to achieve electric connection. The supporting section of the socket adapter increases the contacting area of the insulating essential body and the central pin, thereby avoiding the central pin distort. The supporting section guides the socket plug to locate and connect, thereby achieving stable electrical connection.
