Description

  The present invention relates to a housing case for a hard disk drive capable of connector-connector connection.

  Generally, a hard disk drive includes a drive unit that rotates at a high speed, and accordingly, heat generation, vibration, and sound are generated. For example, there may be a case where a driving sound such as a rotation sound or a seek sound of a hard disk drive mounted on a personal computer or the like is in a quiet room. Especially if you enjoy music. As a countermeasure, the applicant has proposed a housing case for a hard disk drive as shown in Patent Document 1.

  This housing case is a case made of aluminum or copper with a sorbosein (trade name) mat, a sponge-like sound absorbing material, a heat radiating plate, etc., which has a high heat conductivity inside and is also known as a vibration absorbing material. . FIG. 9 shows a procedure for housing the hard disk drive 60 in the housing case 50 configured as described above. First, in step S90, the screw is loosened with a screwdriver, and the case lid 51 attached to the case main body 52 is removed. In the next step S91, the heat sinks 54a, 54b arranged on the sound absorbing materials 53a, 53b and the sorbocein mat can be confirmed inside the case lid 51 and inside the housing case 50. In step S92, the hard disk drive 60 is inserted into the case main body 52. Then, a power supply cable 55 and a signal cable 56 are attached to the connector of the hard disk drive 60 as interface cables, and are pulled out from the notch portion of the rear wall of the case main body 52. Finally, the case lid 51 is attached in step S93.

  The housing case 50 has a structure in which the connector for the hard disk drive 60 is located inside the housing case 50, and therefore the interface cables (the power supply cable 55 and the signal cable 56) are essential. In other words, cable connection is assumed. Therefore, for example, when a large number of hard disk drives are inserted into power supply connectors and signal connectors provided on the backplane to form a disk array (RAID), so-called connector-connector connection (directly without using a cable) Can't connect connector to connector).

Furthermore, since the outer dimensions of the housing case are matched with the outer dimensions of the 3.5-inch hard disk, it is convenient when housing a 2.5-inch hard disk drive and mounting it in the 3.5-inch hard disk bay of the host.

Hereinafter, a housing case for a hard disk drive according to the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view seen from the rear bottom surface of a storage case of a hard disk drive according to an embodiment of the present invention. Reference numeral 100 denotes a box-shaped storage case including a case cover 51 and a case body 52 made of metal such as aluminum or copper. A sorbosein mat 5b is affixed to the top plate portion inside the case main body 52 as shown by a dotted line, and a heat radiating plate 54b is placed thereon. The sorbosein mat 5b is a highly heat-conductive buffer member and has adhesiveness, so that the heat radiating plate is simply held and held in that position. Further, a sound absorbing material 53b is disposed along the inner peripheral wall surface. Similarly, a sorbosein mat 5a and a (second) heat radiating plate 54a are provided on the back side of the case lid 51, and a sound absorbing material 53a is attached to the periphery thereof. The support member (support metal fitting) 6 has an L shape and is screwed into a long hole provided in the heat radiating plate 54b. However, the support member 6 can be moved in the width direction of the stored hard disk drive along the peripheral wall surface. The hard disk drive is held down and supported by an elastic sound-absorbing material.

  The relay substrate 1 is provided at one end of the rear wall of the case body 52. The relay substrate 1 has a structure in which the spacer 4 is fixed with a countersunk screw from two screw holes 10 provided on the rear wall and attached to the other end of the spacer 4 with a screw. On one side surface of the relay board 1, a female connector 3 that fits into an interface connector of a stored hard disk drive is provided. On the other side of the relay board 1, a male connector 2 for external connection for connecting to an external device such as a controller is provided. Corresponding pins of the female connector 3 and the male connector 2 are connected by a wiring pattern on the relay substrate 1.

  The male connector 2 is attached so that the connector front surface 2 a (rear end surface) is flush with the outer surface of the rear wall of the case body 52. Further, the end surface 2 b having the open portion of the male connector 2 is attached so as to be the same plane as the outer surface of the case lid 51 when the case lid 51 is closed. For this reason, the rear wall of the case body 52 and one end of the case lid 51 are provided with cutout portions facing each other so that the male connector can be accommodated in the cutout portion. By attaching the male connector 2 in this way, the position of the male connector 2 can be confirmed from the rear, and the fitting with the connector of the connection destination becomes easy.

  Generally, 2.5-inch and 3.5-inch hard disk drives have a box shape, and the top surface of the box is a flat surface such as an aluminum case that houses the disk drive. The substrate is attached without a cover. An interface connector is provided at the end of the control board. When such a hard disk drive is housed in the housing case 100, the upper flat surface of the hard disk drive is housed in contact with the heat sink 54b of the housing case 100. Therefore, the position of the female connector 3 of the relay board 1 is slightly closer to the bottom surface. There is a gap between the control board of the hard disk drive and the heat sink 54 a of the case lid 51, and there is a gap, and the die-cast part around the board mounting surface is in contact with the heat sink 54 a of the case cover 51.

  Hard disk drive interfaces include ATA specifications and SCSI specifications. Recently, a serial transfer method using a 1-bit data transfer line is becoming widespread from an 8-bit or 16-bit parallel transfer method. The serial transfer system is currently at a high speed of 1.9 Gbps (about 190 MB / s) and is called serial ATA (hereinafter abbreviated as SATA) or serial SCSI (hereinafter abbreviated as SASI). In SATA and SASI, the shape of the interface connector used for the hard disk drive is the same.

  The male connector 2 of the relay board 1 is the same as an interface connector used for SATA or SASI. As shown in FIG. 1, the male connector 2 is provided with a first port 11, a second port 12, and a third port 13 from right to left. Each port is on a mini-board in the connector, and the first port has 7 pins, the second port has 7 pins, and the third port has 15 pins on the front side, back side, and front side. (The drawing circle C1 shows an enlarged front view of the male connector.) The second port is provided with a key portion protruding upward, and the female connector is inserted so that the first port and the third port are reversed. I can't do it.

  For example, in SATA, if the signal lines of the first port 11 are s1 to s7, the configuration is as follows: s1, s4, s7 are ground lines, s2, s3 are input lines to the disk (corresponding to A +, A-), s5 and s6 are output lines from the disk (corresponding to B- and B +). Also, assuming that the power supply lines of the third port are p1 to p15, the configuration is that p4, p12, p5, p6, and p10 are ground lines, p3 is a 3.3V precharge power supply line, and p1 and p2 are 3.3V. The power supply line, p7 is a 5V precharge power supply line, p8 and p9 are 5V power supply lines, p13 is a 12V precharge power supply line, p14 and p15 are 12V power supply lines, and p11 is a spare line. In the conventional parallel interface, the power cable connector and the signal cable connector are different connectors, but here they are integrated into one interface connector. An individual signal line is defined for the second port.

  The 3.5-inch hard disk drive has a width of 101.6 mm, a height of 25.4 mm, a depth of 146 mm, and the like. The 2.5-inch hard disk drive has a width of 70 mm, a height of 9.5 mm, a depth of 100 mm, and the like. The housing case 100 can have an outer dimension adapted to this, and the outer dimension of the housing case 100 that accommodates the 2.5-inch hard disk drive can be matched with the outer dimension of the 3.5-inch hard disk drive. This is convenient when a 2.5-inch hard disk drive with anti-vibration, quiet and heat dissipation measures is installed in a 3.5-inch bay of a personal computer.
