<p>A plug device with a built-in power supply of switch mode power supply type is disclosed. The plug device comprises a printed circuit board (24) upon which a high-frequency transformer (32), a low-voltage capacitor (28) and other components which make up a switch mode power supply are arranged. A first isolating barrier (36) extends form the housing (26) in between the high-frequency transformer (32) and said low-voltage capacitor (28). A third isolating barrier (46) extends form the housing (26) and into a first slot (48) in the printed circuit board (24) and a fourth isolating barrier (48) extends from said housing (26) and into a second slot (44) in the printed circuit board (26). These slots (42, 44) are placed between the high-voltage and low-voltage connection terminals of the high-frequency transformer (32). A second isolating barrier (38) extends from said housing (26) and between the high-frequency transformer (32) and the printed circuit board (24) and beneath said high-frequency transformer (32).</p> |
