Description

Technical Field

[0001] The utility model relates to the technical field of crown springs, and particularly relates to a crown spring jack and a connector which are easy to plug and unplug with large current. Background Art

[0002] A crown spring is a highly reliable jack assembly used in electrical connector products. The two ends of the crown spring are respectively an insertion end and a solder cup end. The insertion end is used for pin insertion, and the solder cup end is used for wire soldering.

[0003] After retrieval, a combined double-crown-spring electrical connection structure with the publication number CN202110454139.3 includes a cable, a male end body, and a female end body that is pluggably connected to the male end body. It also includes an outer crown spring and an inner crown spring both installed on the female end body. The outer crown spring and the inner crown spring are both in a hollow ring shape. 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 collinearly arranged. When the male end body is plugged 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. 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. 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 collinearly arranged and are arranged in sequence along their common line. When the male end body is plugged 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. In the present 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 plugging 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, energy consumption loss, less heat generation, and extend the service life, and has high promotion value.
