ABSTRACT:
The present invention relates to a connecting device of a flexible printed circuit (FPC) in a hard disk drive and more particularly to a connecting device of a flexible printed circuit, which is connected between a head installed at an actuator of the hard disk drive and a printed circuit substrate and removes a bias force generated in the flexible printed circuit, thus transmitting a signal between the head and the flexible printed circuit. The connecting device of the flexible printed circuit for transmitting the signal between the printed circuit substrate installed at a body base and a preamplifier which is connected to a signal cable of the magnetic head at the actuator in the hard disk drive, includes a boss having a hole passing through a center portion and a side hole; a pivot bearing fixed at the boss in order to enable the actuator to be rotated; and a pivot screw for forming a wire hole, and being inserted into a female screw formed within the boss, and then for being fixedly installed at the pivot bearing, thereby being coupled to a connecting wire through the side hole, the hole and the wire hole of the pivot screw.
