The plug has a plug core and an anchor defined by the plug core edge. The anchor is configured to insert into the air gap as a receptacle socket electrically connects with plug pins. The coil is energized and de-energized so as to assist in the insertion or removal of the anchor from within the air gap and the corresponding connection and disconnection of the socket and pins.

An electrical plug and receptacle relying on magnetic force to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one or both of the plug and receptacle can be a magnet, which is preferably a permanent rare earth magnet although electromagnets may also be used. The magnetic element on the plug or receptacle that does not include a magnet is composed of ferromagnetic material. When the plug and receptacle are brought into proximity, the magnetic attraction between the magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

The electrical connection between the switch and the actuator is thus established by means of contacts. The ends of the switch and actuator facing each other are fitted with alignment devices designed so that electrical contact between the switch and the actuator can only be made when the contacts are in a particular position with respect to each other.

A recoverable connector structure and a cradle having the same are provided. The cradle includes a base plate, a fixed stand, a recoverable assembly having a bolt and an elastic body, a support body, a shielding plate, a circuit board, a second connector and a case.
