ABSTRACT:
Disclosed is a plug for an automobile cigarette lighter socket that can be adapted into an automobile cigarette lighter socket of various calilbers ranging from 20 mm to 22 mm. The plug can also be secured tightly in position when inserted into the automobile cigarette lighter socket and is easy to manufacture and assemble. The plug comprises a case body having its surface formed with two opposed openings and two opposed elastic pieces positioned symmetrically with respect to the openings; a conducting strip, which is elastic and substantially ring-shaped, with two sides exposing to the outside of the case body through the openings, respectively; and conducting means, connected between the conducting strip and the electrical outlet of the automobile cigarette lighter socket. With the foregoing arrangement, when the plug is inserted into the automobile cigarette lighter socket, the conductive strip and the elastic pieces on the case body in combination exert a pressure on the inner wall of the automobile cigarette lighter socket so as to secure the plug therein. The plug therefore can be adaptively inserted into cigarette lighter sockets of various calibers.
