PURPOSE: A power supply device for plating a barrel is provided to reduce damage to a barrel even if a metal rod and the plastic barrel are contacted with each other for a long time, and to improve the durability of both the rod and the barrel. CONSTITUTION: A power supply device for plating a barrel(100) comprises a coated lead line(30), a rod(40), and a connector(20). Coated parts on both ends of the coated lead line are taken off. The rod and the connector are compressed and coupled to both ends of the coated lead line. In the connector, both ends of a compressed part have a hopper shape. A plastic buffer part(41) is formed on the bottom of the rod. Recessed grooves(43) are longitudinally formed in a compressed part(42) of the rod. A ring is interposed between the coated lead line and the connector in order to compress the coated lead line. |
