Description

  The present invention relates to a connector connection case of a storage device, and more particularly to a connector connection case of a storage device for connecting a storage device such as a hard disk, CD, DVD, BL (Blu-ray) having an interface with a connector on the host computer side. It is.

  Conventionally, among data storage devices used for personal computers (hereinafter referred to as PCs), data storage devices for installing an OS and various programs are exclusively hard disk devices (hereinafter referred to as HDDs) in terms of access speed and recording capacity. Is adopted.

  The magnetic disk used in the HDD has a plurality of tracks formed concentrically, and each track is divided into a plurality of sectors. Each sector can be written to or read from the sector by accessing the desired sector in accordance with the sector address information. In the data reading process, a signal read from the magnetic disk by the head is subjected to predetermined signal processing such as waveform shaping and decoding processing by a signal processing circuit and transmitted to the host. Transfer data from the host is similarly processed by the signal processing circuit and then written to the magnetic disk.

  As an interface for data transmission between a host such as a computer and the HDD, a protocol such as a SCSI (Small Computer System Interface) interface or an ATA (AT Attachment) interface is generally used.

  In particular, the ATA interface is used in many computers because of its improved interface function and low cost, and is also widely used as an interface for storage devices in other types such as optical disk storage devices. Due to the demand for improvement in recording density and performance of recording media, the demand for the data transmission speed of the ATA interface has become increasingly severe. For this reason, an ATA interface (serial ATA) by serial transmission has been proposed instead of the conventional transmission system by parallel transmission.

  The serial ATA standard has already been developed, and some technologies not used in the conventional parallel ATA are adopted. Along with the change in the transmission method from parallel to serial, a great change is also made in the structure of the connector for connecting the HDD and a host such as a PC.

  In designing the connector, not only the electrical design but also the structural design is important. A connector on the HDD side is mounted on a circuit board of the HDD, and typically the circuit board is fixed to an outer surface of a base constituting the HDD enclosure. When a user connects a connector on the HDD side and a connector on the host side, a pushing operation is performed to ensure mutual fitting by a manual connection operation, so that a large force is applied to the HDD side connector. , Increase the possibility of breakage during connection.

  For this reason, a connector having an improved connection function with the circuit board of the HDD has been developed (see Patent Document 1).

JP 2006-73481 A

  By the way, in the above-mentioned patent document 1, the connector mounted on the circuit board of the HDD is provided with two stiffeners on both side walls of the connector in order to secure the fixing, and the insulation formed of resin. A housing is provided.

  The housing includes a base portion extending in a direction along the side of the circuit board erected on the circuit board, and two plate-like protrusions protruding forward from the base portion. The housing further includes plates on both sides thereof.

  The connector includes a plurality of connection terminals arranged in the housing, and the connection terminals are arranged in a direction along the side of the circuit board, and each of the terminals is connected to a corresponding connector on the host side. A contact portion that contacts the terminal and a connection portion that is connected to the circuit board are provided, and the contact portion is fixed to the protruding portion.

  The two protrusions are formed separately, one protrusion holding a power supply system contact part, and the other protrusion holding a signal system contact part. Each of the plurality of connection terminals extends from the protruding portion through the through hole of the base portion to the circuit board side, and the connection portion is connected to the connection terminal on the circuit board by solder.

  The corresponding connector on the host side is formed with a convex portion that is connected to the fitting concave portion and a concave portion (hole) that is fitted to the protruding portion. The contact portion of the connection terminal is a concave portion of the corresponding connector on the host side. Connected to the corresponding connection terminal.

  The connection terminal of the parallel ATA connector is connected to the host-side connector, and the housings are not connected. On the other hand, in the serial ATA connector structure, the housings are fitted together as described above. For this reason, when the user connects to the host-side connector, a greater force than the parallel ATA connector is likely to be applied to the HDD-side connector, so the connection between the connector and the circuit board is more likely to be damaged than the parallel ATA connector. It has a structure.

  The stiffener formed in a T shape with metal is fitted into the hole of the circuit board and fixed to the circuit board by soldering, and the head part abuts against the upper surface of the side wall part, and the housing is attached to the circuit board. It is fixed.

  In addition to the function of fixing the connector to the circuit board, the stiffener has a function as a stopper that restricts connector movement and prevents damage to the connector, thereby preventing damage at the time of connection between the connection terminal and the circuit board. It can be prevented.

  However, in the connector connection part of the storage device such as the conventional hard disk as described above, the movement of the connector can be prevented by restricting the movement of the connector by a stiffener having a stopper function, but the storage device is configured exclusively. Therefore, not only is the cost high, but the connector is connected to the storage device by direct connection manually, so that the connector is attached and detached every time the various storage devices are mounted. In this case, there is a problem that a work load is applied each time.
