Abstract

Disclosed is a structure for contacting a GND line on a Flexible Printed Circuit (FPC) to a Base Plate without any screws or any other fastening elements. In a HDD system, Grounding of FPC is becoming important for eliminating signal noises. Conventionally for providing a GND contact to a FPC, some elements for fixing the GND line of the FPC to a BASE PLATE, such as screws, are used. But those screws are not good parts for airlighting and downsizing of HDD systems. This invention provides a method for achieving the ciontact between a GND line on a FPC and a BASE PLATE without any screws.

Grounding Contact Structure for a Flexible Printed Circuit

      Disclosed is a structure for contacting a GND line on a
Flexible Printed Circuit (FPC) to a Base Plate without any screws or
any other fastening elements.  In a HDD system, Grounding of FPC is
becoming important for eliminating signal noises.  Conventionally for
providing a GND contact to a FPC, some elements for fixing the GND
line of the FPC to a BASE PLATE, such as screws, are used.  But those
screws are not good parts for airlighting and downsizing of HDD
systems.  This invention provides a method for achieving the ciontact
between a GND line on a FPC and a BASE PLATE without any screws.

      The Figure shows an example for this contacting structure.  A
male connector is provided on a BASE PLATE.  A FPC having through
holes is placed on this connector.  A female connector on FPC is
attached on the male connector so that the GND line on the FPC
contacts the BASE PLATE.

      This constitution provides a fixed contact between the GND line
on the FPC and the BASE PLATE without causing any unprefferble
effects as to the airlighting and downsizing of the HDD system.
