<p>A device for transmitting electric energy to electric equipment, primarily computers and data nets, which device is intended to be connected between a voltage source and the electric equipment. The invention is characterized in that it is provided with a generator (30,31) comprising a piezo-electric element, which generator is intended to be connected to said voltage source and to generate a high-frequency mechanical wave motion, that a bar-shaped transmission member (32) is provided to transmit said motion to a receiver (33-35), which transmission member comprises a non-magnetic and electrically insulating material, in which the mechanical wave motion can be conducted, that said receiver, which is intended to be connected to the electric equipment, is capable to convert said mechanical wave motion into an electrically varying voltage by means of a piezo-electric element (33), which is in a mechanical connection with said transmission member.</p> |
