摘要

A charging gun for charging a charging seat includes a connecting line configured to deliver an electric charge from an electric source, a charging head located at one end of the connecting line, and a number of first pins. The number of first pins is surrounded by a first peripheral wall. The first peripheral wall includes at least one first protrusion protruded from an outer surface thereof. The number of first pins connects to a corresponding number of second pins of the charging seat. The charging seat includes a second peripheral wall surrounding the number of second pins. The diameter of an inner surface of the second peripheral wall is greater than the diameter of the outer surface of the first peripheral wall.
