LONG LEVER WITH A PLASTIC HOLDER

   Disclosed is a long lever structure of Hard Disk drive to improve
the productivity and
cost performance.

    Long lever is consist of a metal lever plate and a plastic
holder, the plastic holder is
assembled to the lever plate.

      Separating the holder from the lever,the parts handling
become easy and improved
the holder productivity.

      And the molding cavity of the holder increased and molding
tact time become shorter
then the total cost could be reduced from the insert mold
type.

Long lever and holder structure are described as below,

       1. Plastic holder (holder) has the arm portion and the hook
and the top shape
is semiglobe [FIG 1] Material is Ultem4001.
2. Metal Lever plate(lever) has crena in the outside.[FIG 2]
3. The holder is assembled to the lever.[FIG 3]

       The top shape of holder ,the datum height [Fig 4] between
the lever plate and the
holder and the rotational center of the long lever are not
changed from the insert
mold type long lever to work the latch function efficiently.
The noise between the base and lever ,cover and lever are also
reduced same as
the insert mold type long lever.

   As the raw material, ultem 4001, which includes the fluorine ,
the rotation friction
between the base pin and the holder is reduced.

   And due to the bend strength of the ultem ,assemble operation
become easy.
