Background
U.S. patent publication No. US2017/0273355a1 (corresponding to world intellectual property organization patent publication No. WO2017/163212a1) discloses that terminals are configured in a ring shape separated from each other, and Pogo pins (Pogo pins) are butted against the terminals.
World intellectual property organization patent publication No. WO2018/202730a1 (corresponding to taiwan patent publication No. TW201842856A) discloses that a first connection portion includes a plurality of terminals constituting a circle and arranged on the same plane, and a second connection portion for mating with the first connection portion includes a plurality of terminals protruding out of the plane.
U.S. patent No. US5,704,792 discloses a plurality of pogo pins contacting a plurality of electrically spaced ring terminals.
In the above prior art, a plurality of conductive terminals are disclosed, which are in a ring shape and located on the same plane, but the forming method of the ring-shaped conductive terminal is generally formed on a substrate by a circuit forming method similar to a printed circuit board, so that the thickness is thin and the conductive terminal is easily worn away, and if the ring-shaped conductive terminal is formed by stamping, the problem of uneven contact ring surface of the ring-shaped conductive terminal is easily caused. Furthermore, a Pogo Pin (Pogo Pin) is usually adopted in a connector, and an effective compression stroke required in an application process of the Pogo Pin is large, and at the same time, due to limitation of an internal structure of the Pogo Pin, a distance that a head portion of the Pogo Pin protrudes out of an interface in a butt joint is several times that of other types of elastic terminals, so that the head portion of the Pogo Pin is easily buckled or bent due to improper external force.
US patent No. US5,409,403 discloses a female end connector comprising three recesses in the form of steps and three annular plates formed by stamping, the male end connector having three protrusions in the form of steps and three annular plates integrally moulded on the protrusions, there being lateral contact between the annular plates of the female end connector and the annular plates of the male end connector. However, this design tends to result in insufficient effective contact pressure between the annular plates of the female and male end connectors, resulting in poor contact. Although the annular plate has a male-female fit to increase the effective contact pressure, the action of the male-female fit increases the force required for insertion and removal, and is not suitable for some devices oriented for easy insertion and removal.
