Common Wire Harness Assembly

Disclosed is a Wire Harness Assembly design used for Head Suspension
Assembly (HSA) in Hard Disk Drives (HDDs).

      Usually the shape of head wire loop from Magneto-Resistive (MR)
slider to Suspension Assembly is vertical and then bent about 90º
shown in Fig. 1.  For the ease of manufacturing, the Harness
Assemblies shown in Fig. 2 was used.

      Currently there are two types of the Harness Assemblies for UP
and DOWN type HSAs.  The reason is that the tube cannot be removed
from the Harness Base Frame from the both front and back surface
sides.

      In order to achieve UP/DOWN Common Harness Assemblies, we
propose two different designs.  Refer to Figs. 3 and 4.
  1.  Make one complete slot in the middle of the Harness Base Frame.
       The Tube is fixed by the slits which are perpendicular to the
       slot.  Then the tube can be removed from the both front and
back
       surface sides after ultra sonic bonding process.  Refer to
Fig. 3.
  2.  Make some cutting slots along the tube.  After ultra sonic
boning
       process, we can cut the Harness Base Frame and remove them
       separately.  Refer to Fig. 4.
