Description

  Embodiments described herein relate generally to an HDD support structure of an information processing apparatus.

  Computers used in the field of social infrastructure are required to be more robust, reliable, and easier to maintain than those required for general-purpose personal computers. There is an industrial computer as a computer that meets such a demand.

  As a storage device for this industrial computer, it is a standard based on SATA (Serial Advanced Technology Attachment) and SCSI (Small Computer System Interface) capable of high-speed data transfer, and it can be replaced from the front panel of the chassis. There is a need for a type of HDD (Hard Disk Drive) unit.

  An example of an industrial computer having this front exchange type HDD unit is shown in FIG. A slot 2 for replacing the HDD unit 40 is provided in the front portion of the housing 1 of the industrial computer 100.

  The HDD 4a is fixed to the HDD tray 4b at the bottom, inserted into the slot 2 as an HDD unit 40 fixed integrally with the HDD tray 4b, guided by the guide rail 6, and fixed to the housing 1 by the front screw portion 4c. Is done.

  Details of the mounting structure of the HDD unit 40 are shown in FIG. FIG. 3 is a side view of the housing 1 as seen in the direction of the arrow from the A-A ′ cross section.

  In FIG. 3, a guide rail 6 for guiding the HDD tray 4 b is installed in the slot 2 of the housing 1 in the tray insertion direction, and a substrate 7 having a connector 8 is provided at the back of the slot 2. The connector 9 provided at the front end of the HDD 4a is pushed into the HDD tray 4 and fixed at a position where it fits.

  In such a configuration, the electrical connection between the HDD 4 a and the connector 8 of the housing 1 can be realized by attaching the HDD tray 4 a to the housing 1.

  The connector 9 at the rear end of the HDD 4a and the connector 8 fixed to the board 7 include the dimensional tolerance of the HDD 4a main body, the dimensional tolerance in manufacturing the HDD tray 4b, and the HDD unit 40 when the HDD 4a is assembled to the HDD tray 4b. It is necessary to design with consideration of error factors such as dimensional tolerance.

  Therefore, in the actual design, an appropriate gap 10 is provided between the HDD tray 4b and the guide rail 6 so that the connector 9 of the HDD 4a and the connector 8 of the board 7 can be fitted within a tolerance.

  In the connector connection in which such an electrical joint is fitted, it is necessary to keep the relative position between the connector contacts constant in order to prevent the electrical joint from being damaged when the HDD unit 40 vibrates. There is.

  Therefore, the conductor portion of each connector is formed as an inclined surface inclined with respect to the insertion / removal direction, and when the HDD is mounted on the main body, the connectors are pressed so that the mutual inclined surfaces are in pressure contact with each other, An electrical connection structure is disclosed in which a board-side connector and an HDD-side connector are fitted and coupled by a force for pushing the HDD (see, for example, Patent Document 1).

  In addition, a magnetic disk device having a configuration in which an HDD and its mounting frame are integrated as a rigid body and mounted between a mounting angle of the housing via a vibration-proof rubber is disclosed (for example, see Patent Document 2).

  In the conventional information processing apparatus such as the industrial computer as described above, the housing panel exposed to the outside of the information processing apparatus is different from the case where the HDD is fixed as a rigid body integrated with the casing of the information processing apparatus. Since it is fixed only on the surface, it is inevitable in terms of structure that the gap 10 is generated inside the housing.

  When an impact or vibration is applied to the entire housing from the outside in the presence of the gap 10, a collision phenomenon occurs between the guide rail 6 and the HDD tray 4b, and sometimes an impact force greater than the acceleration given from the outside is generated. There is a case.

  For the HDD 4a, the impact force causes damage to the internal disk and read head, and the relative displacement between the HDD 4a side connector 9 and the housing side connector 8 increases, resulting in poor contact between the connector conductors (pins). There is a possibility of failure.

  However, the configurations disclosed in Patent Literature 1 and Patent Literature 2 do not disclose a technique for performing vibration isolation of the HDD in a configuration in which the HDD is detachable.

  The present invention has been made to solve the above problems, and in an information processing apparatus having an HDD removable from the entire surface of the housing, the information processing apparatus can be easily attached and detached, and has improved earthquake resistance. An object is to provide an HDD support structure.

  To achieve the above object, the HDD support structure of the information processing apparatus according to the present embodiment connects the first connector fixed to the substrate in the housing of the information processing apparatus and the second connector provided in the HDD, The HDD supporting structure of the information processing apparatus 0 in which the HDD is detachably provided, the housing including a slot for inserting the HDD on a front surface thereof, further fixing the board, and the first connector An HDD support bracket having a screw hole for fixing the second connector and the HDD integrally to the housing, and a guide rail fixed to the housing for guiding the mounting / demounting position of the HDD from the slot, The HDD, an HDD tray that integrally fixes the HDD, a pair of fixing screws that fix both ends of the HDD tray to the front surface of the housing, and the H on the HDD tray A pair of knurled screw portions that are fixed to both sides of D and inserted from the front surface of the housing and screwed into screw holes of the HDD support brackets located at the rear of the slot to fix the HDD tray.
