Abstract

PROBLEM TO BE SOLVED: To improve the degree of freedom on the forming of a cable at the time of connection to an outer unit by constituting a substrate so that a fitting direction can be changed against an electronic unit main body. SOLUTION: PCBA 32 having an interface connector and a power connector 31 is mounted on the base plate 33 of an HDA part. A fitting screw hole 35 is in the direction of an HDA cover 34. Since the fitting screw hole 35 is turned to the direction of the HDA cover 34 opposite to PCBA 32, mounting by changing the direction for rotating PCBA 32 is realized. Then, the directions of the interface connector and the power connector 31 can be changed. Namely, a magnetic disk device is mounted by changing the direction of PCBA 32 and therefore the interface connector and the power connector 31 in the device can be changed to optimum positions by adjusting them to the loading condition of the magnetic disk device.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing that the positions of an interface connector and a power supply connector are changed by changing a mounting direction of a PCBA of a magnetic disk device according to an embodiment of the present invention, and FIG. The figure which showed the head disk assembly (HDA) part of the apparatus. FIG. 3 is a view showing a connector section for connecting a PCBA of the magnetic disk apparatus according to the present embodiment to a base plate of an HDA section, and FIG. 4 is a view showing a conventional magnetic disk apparatus.

Next, the configuration will be described with reference to FIGS. As shown in FIG. 2, the PCBA 32 having the interface connector and the power connector 31 is mounted on the base plate 33 of the HDA section, and the mounting screw hole 35 is directed to the HDA cover 34.

Further, FIG. 3 shows a configuration in which a connector 44 for a preamplifier and a write driver system and a connector 45 for a spindle motor and a voice coil motor control system, which connect the PCBA 42 and the base plate 41 of the HDA section, are mounted at three places. I have.

Next, the interface connector and the power supply connector 21 of the magnetic disk drive according to the present embodiment,
31 and 43 are HDA base plates 23, 33 and 41
The means for mounting the device in a different direction will be described with reference to FIGS. 1, 2 and 3, and also to FIG. 4 showing a conventional magnetic disk drive.

As shown in FIG. 3, the connectors 44 and 45 connecting the PCBA 42 and the base plate 41 are mounted at three locations, so that the orientation of the PCBA 42 with respect to the base plate 41 is changed to the mounting examples 1 and 2 of FIG. The mounting can be performed by changing the direction in three directions as shown in FIG.

At this time, in the conventional magnetic disk device shown in FIG. 4, since the mounting screw hole 13 faces the PCBA 12, mounting the PCBA 12 on the base plate 14 by changing the direction of the PCBA 12 requires the mounting screw hole 13 to be mounted. It cannot interfere with the interface and the power connector 11. However, in the magnetic disk drive according to the present invention shown in FIGS.
By facing the HDA cover 34, which is the opposite direction to the CBAs 22, 32, it is possible to mount the PCBAs 22, 32 in a changed orientation by rotating the PCBAs 22, 32, thereby changing the orientations of the interface connector and the power connectors 21, 31. It becomes possible.

Since the magnetic disk drive according to the embodiment is configured as described above, the following effects can be obtained. That is, the magnetic disk drive according to the present embodiment
By mounting the PCBA 42 with its orientation changed, the interface connector and power connector 2
The positions 1, 31, and 43 can be changed to optimal positions according to the conditions for mounting the magnetic disk device. As a result, it is possible to freely optimize the cable forming to the interface connector and the power supply connector when mounting it on a personal computer or the like, and it is extremely effective also to shorten the cable length to reduce noise and the like. is there. Further, when the size of the housing of a personal computer or the like is reduced, the degree of freedom in the mounting position of the magnetic disk device inside the housing of the personal computer or the like can be greatly improved.

In the present embodiment, the present invention is not limited to the above-described magnetic disk, but can be applied to an electronic device suitable for applying the present invention. Further, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to numbers, positions, shapes, and the like suitable for carrying out the present invention. In the drawings, the same components are denoted by the same reference numerals.
