The interior of the cylindrical housing forms an insulating cavity and an air cavity, which are communicated with each other. The cylindrical insulator is embedded into the insulating cavity, and the four pin contactors are respectively inserted into the cylindrical insulator. One end of each pin contactor stretches into the air cavity, and the other end of each pin contactor is aligned with the outer end of the cylindrical insulator. The outer end of the cylindrical insulator is far from the insulating cavity. Each pin contactor is in a cylindrical structure, and is provided with a through hole in an axial direction, wherein the interior of the through hole is provided with a naked conductor passing through the through hole. One end part of each pin contactor is shaped like a circular truncated cone, and a welding end of each naked conductor is welded at one end of the corresponding pin contactor. The socket mainly cooperates with the four-in circular plug for use.
