US Patent 7557299 Power supply device

The object of the invention is to provide a power supply device capable of reducing the protector size, which includes a protector for receiving a wiring harness and extending the floating wiring harness through an elongated opening therein, a harness winding section free to bend the wiring harness to regulate a minimum radius of curvature of the wiring harness while holding its freedom of movement within the protector, and an elastic member for energizing the harness winding section to lead the wiring harness into the protector. In this power supply device, the harness winding section can be moved in one direction against the energized elastic member in an end area of the elongated opening, and the harness winding section energized by the elastic member can be moved in the other direction in the center area of the elongated opening. Further, the elastic member can be received inside the harness winding section.
