Abstract

Disclosed is a tube/wire clamping method for a suspension used in Hard Disk Drives. The clamping method shown in Fig. 1 has no tube that jumps out of the top surface of a mounting plate, which is defined as the maximum height of the suspension.

Suspension with Improved Third Clamp

       Disclosed is a tube/wire clamping method for a suspension
used in Hard Disk Drives.  The clamping method shown in Fig. 1 has no
tube that jumps out of the top surface of a mounting plate, which is
defined as the maximum height of the suspension.

      To get enough clamping strength by friction, the tube/wire is
extremely curved.  This tube/wire shape is like the second clamp of
the conventional 3370-type of suspension.

      To reduce tube/wire jump after clamping, a tube/wire path is
located on the side of the mounting plate and the curved area of the
tube/wire is in the plane of the mounting plate.  So, even though the
tube/wire is clamped severely, the tube/wire never jumps out of the
top surface of the mounting plate.  Also, a tapered edge of the
mounting plates side edge and an extended load beam side pattern
prevent the tube/wire from moving during and after clamping.

      The advantages of this design are:
1)   No tube jump out of the top surface of the mounting plate, which
is defined as the maximum height of suspension.
2)   Stiffer clamping strength between suspension and tube/wire.
3)   No clamping process change is required.
