<p>PURPOSE:To enable to eliminate the possibility of generation of a defective contact, an electric shock and a short circuit by a method wherein electric energy is transmitted by electromagnetic induction instead of contacting metal pieces. CONSTITUTION:Windings 2 are wound around U-shaped iron cores 1 and two parts of transformers are constituted with them. Two cases 4 are formed by an electrically insulated material which transmits magnetic force (plastic, for example). When a connector is used, its primary side 11 and the secondary side 22 are firmly fixed, and they are fixed by screwing a fixing part 33 into the screw part 5 of the secondary side 11. The collar 6 of the secondary side 22 of a connector is turned to a stopper 33. When AC voltage is applied from either of the codes 11 and 22, electric energy is transmitted to other side by the action of the transformer. As the transmission of the electric energy is performed by electromagnetic induction, said energy is transmitted smoothly even when the case 4 is formed by electric insulating material.</p> |
