Abstract

Disclosed in this article is a design for a flexible cable for Hard Disk Drives (HDDs). The flexible cable described here will prevent electrical shortage. The flexible cable that connects the VCM and the head to the PCB will be stretched towards the connecter of the spindle motor and PCB so that the pin on the connector will not hit the HDA and cause a shortage.

Insulation Method with Extended Flexible Cable

      Disclosed in this article is a design for a flexible cable for
Hard Disk Drives (HDDs).  The flexible cable described here will
prevent electrical shortage.  The flexible cable that connects the
VCM and the head to the PCB will be stretched towards the connecter
of the spindle motor and PCB so that the pin on the connector will
not hit the HDA and cause a shortage.

      The Figure, (a,b) shows this configuration.  The spindle motor
connector which has four pins will easily be loosened.  By streching
the base film as in Figure (b), the pins on the connecter will be
insulated by this base film and not cause a short due to contact to
the base.

      The connector for the spindle motor has only four pins and
therefore has less friction compared to the VCM - head connector.
The tension of the flexible cable pulls the connector and sometimes
loosens the connection.  The base plate which is just outside this
connector will cause a short and may also damage the PCB or the
spindle motor.  Streching the flexible cable will prevent this.

In this way, electrical insulation at the connector can be
established at no extra cost.
