Abstract
The present invention provides a thin actuator which is used for transferring a head of a magnetic disk drive, and prevents resultant malfunctions. In a moving part of the actuator in which a coil, holding member, housing, and plate-shaped terminals are integrated by resin molding, the plate-shaped terminals are provided in the holding member in a coil moving direction, and the plate-shaped terminals and connecting parts provided in a conductor end part of the flexible circuit board are brought into surface contact, and these contacted portions are electrically connected with solder.
Claims20
An actuator comprising:
- yokes confronting one another and defining a predetermined space therebetween;
- a movable coil between said yokes;
- a permanent magnet between said yokes and attached to at least one of said yokes, said permanent magnet for applying a magnetic field to said movable coil;
- a holding member for holding said movable coil, said holding member having a groove therein;
- a housing having a first end to which said holding member is attached, and also having a second end to which a functional member can be attached;
- a flexible circuit board for transmitting a current to said movable coil;
- and
- two terminals having end parts to which ends of a strand forming said movable coil are electrically connected, respectively, within said holding member;
- wherein said groove is constructed and arranged to receive said flexible circuit board such that when said flexible circuit board is inserted into said groove said two terminals become electrically connected to said flexible circuit board.
