Abstract
The present invention provides a thinner actuator which is used for transferring a head of a magnetic disk drive and the like, and prevents resultant malfunctions. In a moving part of the actuator in which the coil 1, the holding member 2, the housing 3, and plate-shaped terminals 5a and 5b are integrated by resin molding, the plate-shaped terminals 5a and 5b are provided in the holding member 2 in the coil moving direction 6, and the plate-shaped terminals 5a and 5b and the connecting parts 7a and 7b provided in the conductor end part of the flexible circuit board 7 are brought into surface contact, and the contacted portions are electrically connected with solder.
Claims7
An actuator which comprises:
- plural yokes which confront to each other with providing a predetermined space therebetween;
- a coil which is wound and placed movably between the plural yokes;
- a permanent magnet which is located between the plural yokes and attached to at least one of the yokes, and applies a magnetic field to the coil;
- a holding member for holding the coil, which is made of a thermoplastic resin;
- a housing to which the holding member is attached at one end and a functional member can be attached at the other end;
- and a flexible circuit board which transmits a current from the outside to the coil, wherein
- portions of two plate-shaped terminals to which opposite end parts of a strand of the coil are electrically connected are buried in the holding member and exposed parts of the both plate-shaped terminals are electrically connected to a conductor part of the flexible circuit board.
