Abstract
An arm coil assembly includes a drive arm having at least two grounding pins formed on a mounting region thereof and a voice coil fixed on the tailing end of the drive arm for controlling the drive arm. The grounding pins are provided for electrically connecting with a flexible printed cable assembly by extending through at least two mounting holes formed on the flexible printed cable assembly. Each grounding pin has a slot formed thereon to clamp the flexible printed cable assembly. The arm coil assembly of the present invention having grounding pins with slot structure to clamp the flexible printed cable assembly which is mounted on the drive arm to form an arm flexible cable assembly, thus, the flexible printed cable assembly can be pre-mounted onto the arm coil assembly without using any additional fixtures or tools, therefore simplifying the mounting process and reducing the manufacturing cost thereof. The invention also discloses an arm flexible cable assembly and a disk drive unit including the same.
