Abstract

Disclosed is a structure for wire crimping for use in Hard Disk Drives (HDDs) and their Head Gimbal Assembly (HGA). The crimps which are used for mounting the head wires and tube which it encloses are slanted to match the orientation of the flex cable.

Slanted Tube Holder on Head Gimbal Assembly

      Disclosed is a structure for wire crimping for use in Hard Disk
Drives (HDDs) and their Head Gimbal Assembly (HGA).  The crimps which
are used for mounting the head wires and tube which it encloses are
slanted to match the orientation of the flex cable.

      Crimps are commonly used on HGAs to fix the head wires and
tube.  The crimps are usually oriented parallel to the mounting
plate,
as shown in Fig. 1.   When such an HGA is assembled to a carriage,
the angle of the flex cable relative to the mounting plate must be
compensated during the assembly process.  Such a process requires
more handling and is less efficient.  Also, bending the tube in this
way may  result in tube loosening and, therefore, interference of the
tube and disk.

      An example of the disclosed structure is shown in Fig. 2.  The
crimps on the HGA are formed so that the tube is in line with the
flex cable.  In this way, the manufacturing process is simplified and
the tube  to disk interference is prevented.
