It also includes an outer crown spring and an inner crown spring that are both installed on the female end body. The outer crown spring and the inner crown spring are both hollow rings. The outer crown spring is sleeved on the outer peripheral surface of the inner crown spring, and the central axes of the outer crown spring and the inner crown spring are collinear. When the male end body is inserted into the female end body, both the outer crown spring and the inner crown spring are in contact with the outer peripheral surface of the male end body, so that the electrical conduction contact area of the male end body is increased. In this application, the outer crown spring is sleeved on the outer peripheral surface of the inner crown spring, and both the outer crown spring and the inner crown spring are in contact with the male end body, which can not only make the insertion firm and stable, but also effectively increase the electrical conduction contact area, effectively avoid poor contact, can carry a larger current with the same cross-sectional area, reduce the contact resistance, save energy and reduce heat generation, and extend the service life. It has high promotion value. The inner crown spring is integrally bent with a plurality of first elastic abutting pieces, and each of the plurality of first elastic abutting pieces is concavely provided with a first abutting portion and a third abutting portion; the first abutting portions of the plurality of first elastic abutting pieces are arranged in a circular array along the central axis of the inner crown spring to form a first conduction contact ring, and the third abutting portions of the plurality of first elastic abutting pieces are arranged in a circular array along the central axis of the inner crown spring to form a third conduction contact ring. The outer crown spring is integrally bent with a plurality of second elastic abutting pieces, and each of the plurality of second elastic abutting pieces is concavely provided with a second abutting portion. The second abutting portions of the plurality of second elastic abutting pieces are arranged in a circular array along the central axis of the outer crown spring to form a second conduction contact ring. When the outer crown spring and the inner crown spring are sleeved, the plurality of first elastic abutting pieces and the plurality of second elastic abutting pieces are arranged at intervals and staggered with each other. The central axes of the first conduction contact ring, the second conduction contact ring, and the third conduction contact ring are collinear and are arranged in sequence along their common line. When the male end body is inserted into the female end body, the first abutting portion, the second abutting portion, and the third abutting portion are all in contact with the outer peripheral wall of the male end body.
