What is claimed is:
1. Field of the Invention
The present invention generally relates to a hard disk drive with a connector assembly for connection between the hard disk drive and a computer system, and more particularly to a hard disk drive incorporating a connector assembly with simplified configurations and smaller weight.
2. Description of the Related Art
Various data storage devices are installed in electronic apparatus for communication and handling of data. Such devices include, for example, hard disk drives, floppy disk drives and Compact Disk-Read Only Memory (CD-ROM) drives. As computers have evolved into more sophisticated computer systems with smaller dimensions and lighter weight, efforts have been directed at providing increasing amounts of data storage with smaller weight or physical dimensions.
Typically a hard disk drive contains a magnetic disk that is rotated by a spin motor. The drive unit also has a head that magnetizes and senses the magnetic field of the disk. The head is typically located at the end of an actuator arm which can move relative to the magnetic disk. The actuator arm, motor and other components of a typical disk drive are installed in a rectangular container and communicate with a circuit board of a hard disk drive mounted in the container for processing. The circuit board of the hard disk drive is connected with another circuit board by a hard disk drive connector assembly for communication and handling of data.

It is thus desirable to provide a hard disk drive with connector assembly with simplified configurations which overcomes the problems discussed above.
Accordingly, an object of the present invention is to provide a hard disk drive with a connector assembly for connection between the hard disk drive and a computer system, and said hard disk drive has a simplified configuration and smaller weight.
To achieve the above object, a hard disk drive with connector assembly comprises a baseplate, a disk stack, a head stack, a spindle motor and a connector assembly. The connector assembly includes a connector and a circuit board. The connector comprises a insulative base and a plurality of contacts extending from the insulative base and being soldered to the circuit board at one end thereof the baseplate receiving the circuit board and the connector, includes a bottom wall, two side walls and two separating wall perpendicularly extending from the bottom wall in one end portion thereof. The insulative base of the connector, the bottom wall, the two side walls and the two separating walls corporately form three contacts receiving housing.
Other objects, advantages and novel features of the present invention will be drown from the following detailed description of preferred embodiments and the accompanying drawings.

In the illustrated embodiment of the present invention, the disk stack 90 comprises two hard disks 70. The disk stack 90 is mounted onto the spindle motor 80. A surface of each hard disk 70 is coated with a thin layer of magnetized material, for storage of information. The spindle motor 80 comprises a stator 84 and a rotor 86. The stator 84 comprises a central tubular base portion 88, and an circumferential flange 82. The flange 82 defines a plurality of fixing holes 83 therein for extension of screws 81 thereinto. A plurality of stator laminations 72 extends radially outwardly from the base portion 88. A winding 74 is wound around each stator lamination 72. A pair of bearings 76 is received in the base portion 88, the bearings 76 rotatably connecting the rotor 86 to the stator 84.
Referring particularly to
The head stack 50 of the present invention is of the moving coil type. The head stack 50 comprises a head positioner assembly 54 defining a fixing bore 56 therein. The head positioner assembly 54 supports a plurality of individual cantilever arms 58 each having a read/write transducer head 59 at a distal end thereof. A suitable actuator motor (not shown) such as a movable coil motor is provided, together with a corresponding motor controller 62. The actuator motor and motor controller 62 are used to displace the read/write transducer heads 59 through generally radial traverses relative to the hard disks 70.
In assembly, the spindle motor 80 is received in the through opening 12 of the baseplate 10, with the fixing holes 83 of the spindle motor 80 aligned with the screw holes 14 of the step 13. The screws 81 extend through the fixing holes 83, and engage in the screw holes 14 of the step 13. The hard disks 70 of the disk stack 90 are fixed on the hub 94 of the rotor 86 by the clamp (not shown).
To mount the head stack 50 on the baseplate 10, a screw shaft 52 extends through the fixing bore 56 of the head stack 50 and engages in the screw hole 16 of the baseplate 10. The read/write transducer heads 59 are in close proximity with respective upper and lower surfaces of the hard disks 70. A damper (not shown) can be attached under the head stack 50 for stable support and suitable vibration absorption. Thus dynamic head loading properties of the read/write transducer heads 59 are improved.

The circuit board 140 is secured to the connector 100 by engaging in the slots 131 of the base 110 and having the tail sections 132, 134, 136 of the contacts 124, 126, 128 soldered thereon. The circuit board 140 defines a plurality of fixing holes (not labeled) corresponding to the pillars 32 for extension of pillars therethrough. A plurality of screws 160 engage in the screw holes of the pillars 32 thereby securing the circuit board 140 to the baseplate 10.
When the circuit board 140 is mounted to the baseplate 10, the base 110 of the connector 100 abuts against the shoulders 33 of the baseplate to insure the stability of the connector 100. The front face 118 of the insulative base 110, the bottom wall 36 and the two side walls 39, together with the two separating walls 34 perpendicular to the bottom wall 36, corporately defines three receiving housings for the corresponding contacts 124, 126, 128.
