CONTACTLESS COUPLING AND METHOD FOR USE WITH AN ELECTRICAL APPLIANCE

摘要

The present invention relates to a coupling and various methods of use of the coupling. In one embodiment the invention provides a coupling for use with an appliance operated by a power supply, which coupling allows mounting/dismounting of the appliance without electrical isolation from the supply said coupling comprising: a) a mounting member having a first encapsulated transformer element and suitable controls connectable to the power supply, said member being suitable for fixing to a structure; and b) a holder member engageable with said mounting member, wherein the holder member is suitable for holding or for connecting thereto an appliance, said holder member having other suitable controls and a second encapsulated transformer element able conduct power to an appliance; c) wherein engagement of the first and second members is able i) to cause induction of current in the second encapsulated transformer element enabling powering of an appliance and ii) is able to cause a signal to be carried between the controls and an appliance to control and/or monitor the appliance; and wherein disengagement of the first and second members results in no induction and no carriage of the signal.
