[Industrial applications]

 The present invention relates to a connecting device for a disc device or the like in which a connecting portion of a connecting member fixed to a body of the disc device or the like with a fastening member is detachably arranged in a connecting portion of the device body.

[0002]

[Prior art]

 By downsizing computers, some of the work that was done with conventional mainframe computers is now done with workstations and personal computer networks. Even in this case, the data storage device of the computer is required to have high speed and large capacity, and as the importance of the data to be handled increases, the reliability of the data and the ease of maintenance are required. It Therefore, fault tolerance technology developed and used for mainframe computers is essential for personal computers and the like.

As a data fault tolerance data storage of a mainframe computer which has been conventionally used, there is a method of writing the same data in parallel by using two drives. However, with this method, it is necessary to prepare a disk capacity that is twice the required capacity, and to stop the system when replacing a failed disk. Moreover, its processing speed cannot be faster than the speed of a single drive.

Therefore, a device (disk array) has been proposed in which data to be exchanged with a host computer is disassembled and reorganized by a dedicated disk controller to read / write in parallel to a plurality of disk drives. As a result, the speed of data processing can be increased, the reliability of data can be improved by writing the parity information, and the storage capacity can be efficiently increased.

In addition, the mainframe technology has been expanded to the area of workstations and network file servers, and it has almost the same functions and performance as an intelligent array subsystem (IAS), and is mounted on a 5.25-inch drive base. A miniaturized one (microarray) has been proposed.

[0006] For example, five drives (disk devices) are arranged in this microarray, and data and parity information for error correction are stored in this drive, and even if one drive fails, the data is regenerated. It is configured to be built. In other words, the microarray is configured to decompose the data sent from the host into fixed lengths, generate parities, and record this information in each drive. When the drive fails, the microarray is configured to display, for example, by changing the emission color of the status lamp and emit a warning sound.

In addition, a connector substrate, which is a connecting member, is fixed to the main body of the drive with bolts or the like which are fastening members. A microarray is a socket that is a connection part of a relay board (drive backplane) to which an extension board on which the edge connector pattern of the connector board of the drive is arranged can be plugged and unplugged and electrically connected. It is configured so that it can be installed by slot-in.

Therefore, since the drive and the microarray have a slot-in structure, when the drive fails and the drive is repaired, the failed drive can be easily removed even during the communication with the host. can do. Then, when the repaired drive is mounted and the reset operation is performed, the microarray starts rebuilding the data stored in the drive before the repair. Then, the reconstructed data is stored in the repaired drive. The process in this case happens in the background, independent of the host, so the user can continue to access the data.

[0009]

[Problems to be solved by the device]

 By the way, as described above, the conventional microarray is configured so that it can be mounted by slotting the extension board of the drive (disk device) into the socket of the drive backplane (relay board). FIG. 8 shows a conventional slot-in configuration.

In FIG. 1, reference numeral 70 denotes a relay board, and a socket 71 is fixed to the relay board 70 with solder 72. In addition, the soldering is performed on the lead wire of the socket 71. As shown in FIG. 8B, this socket 71 is arranged so that its insertion port P is orthogonal to the mounting surface 70 a of the relay board 70. Further, the socket 71 is formed with a taper portion 71a on the insertion port P side. 8A is a side view of the slot-in configuration, and FIG. 8B is a plan view of the slot-in configuration.

Reference numeral 73 is a connector board of the disk device, 74 is a drive board (see FIG. 8B), and a connecting member 75 extending from the drive board 74 is interposed between the connector board 73 and the drive board 74. ing. The connector board 73 is fixed to the connecting member 75 of the drive base plate 74 by bolts 76 as fastening members. The connector board 73 is made of, for example, glass epoxy resin. Further, the bolts 76 on the side of the relay board 70 are arranged in the vicinity of an extension board 73a described later, as shown in FIG.

As shown in FIG. 8B, a connector 77a is fixed to the connector board 73 by connector pins 78a. A connector 77b is fixed to the drive board 74 by a connector pin 78b. Then, as shown in FIG. 8B, connectors 77a and 77b are connected between the connector board 73 and the drive board 74.

Further, the connector board 73 is provided with an extension board 73a as shown in FIG. 8A. A conductor 73b is arranged on the extension board 73a. Then, the conductor 73b comes into contact with a conductor (not shown) of the socket 71.

As described above, the disk device is mounted by press-fitting the extension board 73a of the connector board 73 into the socket 71 as shown by the chain double-dashed line in FIG. 8B. Since the bolts 76 on the relay board 70 side of the connector board 73 are arranged near the extension board 73a, when the disk device operates and a disk (not shown) rotates, the vibration of the drive board 74 is directly transmitted through the connector board 73. There is a case where it is transmitted to the socket 71 of the relay board 70 and causes a connection failure of an electronic component (not shown) arranged on the relay board 70.

Further, as shown in FIG. 8C, when the socket 71 is soldered to the relay board 70, the insertion port P of the socket 71 is often soldered obliquely to the mounting surface 70 a of the relay board 70. . 8C is a cross-sectional view taken along the line I-I of FIG. 8A.

When the connector board 73 is mounted while the socket 71 is obliquely soldered, the extension board 73a of the connector board 73 is connected in a bent state. Therefore, stress is accumulated on the base side (bolt 76 side) of the extension board 73a, and a load is generated on the conductive portion 73b and the bolt 76. In addition, there is a problem in that the conductive portion 73b and the unillustrated conductive portion of the socket 71 may cause poor contact.

Therefore, an object of the present invention is to prevent a connection failure between the connecting portion of the disk device or the like and the connecting portion or the like of the apparatus body, and to reduce the load on the connecting portion or the like.

[0018]

[Means for Solving the Problems]

 In the first invention, the connecting portion of the connecting member fixed to the main body of the disk device or the like by the fastening member is arranged so as to be detachable from the connecting portion of the device body, and the fastening member is separated from the connecting portion of the connecting member. And a hole is formed between the connecting portion of the connecting member and the fastening member.

In the second invention, the connecting portion of the connecting member fixed to the main body of the disk device or the like with the fastening member is arranged so as to be detachable from the connecting portion of the device body, and the fastening member is removed from the connecting portion of the connecting member. The holes are formed at positions separated from each other, and a hole is formed between the connection portion of the connection member and the fastening member, and at the same time, a clearance is provided between the fastening member and the connection member on the connection portion side of the connection member. It is a thing.

[0020]

[Action]

 In the first invention, the extension board 31 which is the connecting portion of the disk device 2 is inserted into the socket 51 which is the connecting portion of the cabinet 6 which is the main body of the device. When the drive mechanism of the disk device 2 or the cabinet 6 is driven in a state where the extension board 31 and the socket 51 are connected, the vibration generated in the drive mechanism of the disk device 2 or the cabinet 6 is connected to the disk device 2. It is transmitted to the connector board 30 which is a member. Since the bolt 8 which is a fastening member for fixing the connector substrate 30 to the main body 2a of the disk device 2 is arranged at a position separated from the extension board 31, and the hole 7 is formed between the extension board 31 and the bolt 8. Thus, the vibration transmission path of the vibration of the connector substrate 30 transmitted to the connecting portion between the extension board 31 and the socket 51 becomes long. Therefore, the vibration transmitted to the connecting portion is attenuated, so that the connection failure of the electronic components arranged on the connector substrate 30 is prevented, and the stability of the performance of the disk device 2 and the like is increased.

In the second invention, the extension board 31 which is the connecting portion of the disk device 2 is inserted into the socket 51 which is the connecting portion of the cabinet 6 which is the main body of the apparatus. When the mounting direction of the socket 51 is normal, the extension board 31 and the socket 51 are connected as specified. When the mounting direction of the socket 51 is abnormal, the extension board 31 and the socket 51 are connected with the connector board 30 corresponding to the direction of the socket 51. In this case, the connector board 30 is easily bent by the hole 7 of the connector board 30 and escapes to the bolt 8 and the connector board 30. For example, a gap D between the head 8a of the bolt 8 and the connector board 30 causes the connector board 30 to move. Since the flexure of the substrate 30 is not regulated, the extension board 31 is securely inserted into the socket 51, and the contact between the extension board 31 and the socket 51 becomes good. Therefore, the connection failure between the extension board 31 and the socket 51 is prevented, and the stability of the performance of the disk device 2 and the like is increased. Further, stress is not accumulated on the base side (bolt 8 side) of the connector board 30, and no load is applied to the connecting portion between the extension board 31 and the socket 51 or the bolt 8, so that damage to the disk device 2 or the like is prevented.

Further, as shown in FIG. 6, a gap D is set between the connector board 30 and the heads 8 a of the upper and lower bolts 8 on the extension board 31 side. The gap D serves as an escape when the connector board 30 is bent. The gap D is, for example, about 2 mm in this example.

Further, in the disc device 2, a drive base plate 74 shown in FIG. 8B is arranged on one end side of the main body 2a. A connecting member 75 (see FIG. 8) extended from the drive substrate 74 is interposed between the drive substrate 74 and the connector substrate 30 as in the example of FIG. The connector board 30 is fixed to the connecting member 75 of the drive board 74 by the bolt 8. As in the example of FIG. 8, the connector 77b of the drive board 74 and the connector 77a of the connector board 30 are connected.

As shown in FIG. 5, in the cabinet 6, five rails 40 are arranged in parallel at the portions corresponding to the guide portions 20 of each disk device 2. The rail 40 has an engagement hole 41 formed on the front side thereof so as to engage with the locking piece 24 of the stopper 22 of the disk device 2. The engagement hole 41 is set so that both ends of the locking piece 24 do not collide with the rail 40 when the disk device 2 is housed in the cabinet 6.

In FIG. 5, reference numeral 50 denotes a drive backplane (relay board), and a socket 51 of the drive backplane 50 is fixed with solder 55 so as to correspond to the extension board 31 of the disk device 2. As shown in FIG. 6A, the socket 51 is arranged so that its insertion port P is oriented in a direction orthogonal to the mounting surface 50 a of the relay board 50. Further, the socket 51 has a tapered portion 51a formed on the insertion port P side. The drive backplane 50, the CPU board 52, and the memory board 53 are connected to the SCSI board 54, respectively.

As shown in FIG. 5, the cabinet 6 is provided with a stopper portion 42 for positioning the insertion position of the disk device 2 on the rear side of the rail 40. In addition, the cabinet 6 is provided with support portions 43 for mounting the lid 4 on the lower left and right sides on the front side thereof.

Further, an upper panel 44 is mounted above the cabinet 6. Further, as shown in FIG. 5, the upper panel 44 is provided with a support portion 45 for fixing a support shaft (not shown) of the lid 4 on the insertion port side. Then, the support shaft of the lid 4 engages with the cabinet 6 and the support portions 42 and 45 of the upper panel 44, so that the lid 4 is mounted on the cabinet 6. The upper panel 44 has the drive back plane 50 fixed to the other end.

In the microarray 1, when the disk array S is powered on and started up, only the status lamp R2 of the display unit 3 lights up in red. When the disk array S rises and enters a steady state, the status lamp R2 changes from red to green. In the communication state between the host computer and the disk array, the status lamp R2 lights in green and the access lamp R1 lights in orange.

When the disk device 2 fails, the access lamp R1 is turned off and the status lamp R2 changes from green to red. In this case, the disk array S 2 also emits a warning sound, for example. Then, the user recognizes that the disk device 2 in which the color of the status lamp R2 has changed to red has failed, and repairs or replaces the disk device 2.

To remove the defective disk device 2 from the cabinet 6, for example, the reset button R3 is pressed. As a result, the removal of the disk device 2 is transmitted to the disk array S. Then, the failed disk device 2 is removed from the cabinet 6 and repaired.

The disk device 2 that has been repaired or the like is inserted into the removed portion. After that, when the reset button R3 of the inserted disk device 2 is pressed, only the status lamp R2 lights up in red as when the power source was turned on. After that, the access lamp R1 and the status lamp R2 are turned on in response to the same operation as described above.

To mount the disk device 2 in the cabinet 6, the guide portion 20 of the disk device 2 is inserted along the rail 40. Then, as shown in FIG. 6A, the extension board 31 of the connector base plate 30 faces the insertion port P of the socket 51. Further, when the disk device 2 is inserted, the back surface of the disk device 2 contacts the stopper 42 of the cabinet 6. In this state, as shown in FIG. 6B, the extension board 31 of the connector board 30 is fitted into the socket 51, and the extension board 31 and the socket 51 are connected as specified. As a result, like the example of FIG. 8, the conductor of the extension board 31 (not shown) comes into contact with the conductor of the socket 51.

When the mounting direction of the socket 51 is soldered obliquely to the mounting surface 50a of the relay board 50 as shown in FIG. 6C, the connector board 30 is mounted as shown in FIG. 6C. The extension board 31 and the socket 51 are connected to each other in a state of being bent corresponding to the direction of the socket 51.

Further, according to this example, the connector board 30 is easily bent by the elongated hole 7 of the connector board 30, and the gap D between the head 8 a of the bolt 8 and the connector board 30 allows the connector board 30 to be bent. Since the flexure of the disk is not regulated, the contact between the extension board 31 and the socket 51 can be made good, and the stability of the performance of the disk device 2 and the like can be increased.

Further, according to this example, stress is not accumulated on the base side (bolt 8 side) of the connector substrate 30, and no load is generated on the connecting portion between the extension board 31 and the socket 51 or the bolt 8. It is possible to prevent damage to the disk device 2 and the like.

When the extension board 31 and the socket 51 are connected, the locking piece 24 of the stopper 22 comes into contact with the front side of the rail 40 and the button 23 moves downward. Therefore, the disk device 2 cannot be removed from the cabinet 6 unless the engagement between the locking piece 24 and the engagement hole 41 is released.

When the disk device 2 is driven to rotate a disk (not shown) in a state where the extension board 31 and the socket 51 are connected to each other, vibration generated in the main body 2a of the disk device 2 causes the drive substrate 74 shown in FIG. It is transmitted to the connector substrate 30 via (the connecting member 75 and the bolt 8). The vibration of the connector substrate 30 is transmitted from the bolt 8 to the socket 51 between the extension board 31 and the bolt 8 through the elongated hole 7.

According to this example, since the vibration transmission path of the vibration of the connector substrate 30 transmitted to the connecting portion between the extension board 31 and the socket 51 is lengthened and the vibration is attenuated, the electronic components arranged on the connector substrate 30 are It is possible to prevent connection failure, etc., and increase the stability of the performance of the disk device 2, etc.

Further, since the elongated hole 7 is formed in the connector substrate 30, the air from a fan for cooling (not shown) passes through the elongated hole 7 and is heated by the operation, so that the main body 2 a of the disk device 2 (drive substrate 75 ), The main body 2a can be effectively cooled.

To remove from the cabinet 6 the disk device 2 whose status lamp R3 has changed from green to red due to a failure, the button 23 in the state of FIG. 6B is moved upward. As a result, the engagement piece 24 and the front side of the engagement hole 41 of the rail 40 do not face each other, that is, the engagement between the engagement piece 24 and the engagement hole 41 is released. When the disk device 2 is moved to the front side in this state, the disk device 2 can be removed from the cabinet 6 through the state of FIG. 6A.

FIG. 7 is a block diagram of the microarray 1 of the embodiment. In the figure, 90 is a SCSI controller of the microarray 1. When this S CSI controller 90 is connected to the SCSI adapter 92A of the host system 92 via the SCSI bus 91, the information of the host system 92 passes through the SCSI board 54, the memory board 53, the CPU board 52, and the drive backplane 50. It is stored in the disk of the disk device (drive) 2 via the disk.

In the above embodiment, the example applied to the disk device is shown, but this idea can be applied to a recording / reproducing device using a tape or the like as a recording medium.
