Abstract: A connecting device and an assembly of the connecting device and a mating device are provided. The connecting device includes an insulating main body, a plurality of terminals, a magnet set, an inner housing, a crown leaf spring, an outer housing, and a wave spring. The plurality of terminals are disposed on the insulating main body, the magnet set is disposed on the insulating main body, and the inner housing is sleeved around the insulating main body. The wave spring and the crown leaf spring are each disposed between the inner housing and the outer housing, and abut the inner housing, so that the insulating main body, the plurality of terminals, the magnet set, and the inner housing are arranged in a floating state.

Abstract: A connector with a direct locking and a rotational pre-ejection function is provided. The connector includes an insulated body, a plurality of terminals, an inner shell, an outer shell, a fastener, an ejector, a first elastic element, and a second elastic element. A plurality of push blocks are disposed in the outer shell, the ejector has a plurality of slope surfaces, and the push blocks are in contact with the slope surfaces, respectively. When the connector and a mating connector are inserted into each other, snap bodies of the fastener and fastener bodies of the mating connector can be snapped into each other to be directly locked. When the connector and the mating connector are to be separated from each other, the outer shell can be rotated to cause the snap bodies to disengage and to cause the push blocks to rotate while in contact with the sloped surfaces to effect ejector rods to move forwardly to eject the mating connector.
