Description

  The present invention relates to a SATA interface module, and more particularly to a SATA interface module that can be used in a removable device or an external device to provide a power control function to these devices.

  High-speed transmission and high stability are desired, and a new computer transmission interface, Serial ATA (Serial Advanced Technology Attachment, hereinafter referred to as SATA) interface storage device, has been born. Therefore, related companies started research and development of peripheral devices compatible with the SATA interface. Examples of such devices include a computer removable device (Mobile Rack) and an external device (External Enclosure). The SATA interface signal is composed of a 7-pin signal segment and a 15-pin power segment. However, in the process of signal transmission, the contacts and adapters between them are too frequent, and problems such as signal attenuation, delay, and down are likely to occur.

  In order to avoid such drawbacks, the related contractor directly installs the adapter of the SATA interface on the rear surface of the outer casing of the removable device, and inserts the inner casing into the outer casing so that the adapter is attached to the receptacle on the rear surface. As described above, a connection can be formed between the signal of the storage device of the SATA interface and the power connector. With such a signal and power supply connection method, the best signal transmission effect can be obtained, but since the power supply unit is directly fitted and connected, a removable device of a conventional IDE (Intelligent Drive Electronics, hereinafter referred to as IDE) interface. Power control and / or status display as in This makes it difficult to confirm that the storage device of the inner casing is in a non-operating state and to attach and detach it. Therefore, the installation of a power switch on a removable device or an external device of the SATA interface has become a difficult problem for manufacturers to overcome.

In order to solve the disadvantage that the power switch cannot be installed in the computer removable device having the SATA interface as described above, the present inventor has developed [SATA Mobile Rack with Power Control] [Patent Document 1] and has taken another path. Opened and modularized adapter and circuit board.

  An object of the present invention is to provide a SATA interface module having power control means so that the adapter and the circuit board in the “SATA mobile rack having power control” can be modularized in different types of apparatuses.

The SATA interface module of the present invention has an adapter and extends the signal segment and the power supply segment connector from the inside of the adapter, and extends the signal cable and the power supply cable to the outside of the signal segment and the power supply segment, respectively. ,
A circuit board is provided, a power input receptacle is provided outside the circuit board, the power cable is directly coupled to a predetermined contact of the circuit board, and a power switch is coupled between the power cable and the power input receptacle. Thus, it is possible to control power on / off.

  The SATA interface module of the present invention is not connected to the storage device of the removable device or the external device via the circuit connection on the circuit board but directly to the computer host via the signal cable, so the SATA interface module of the present invention is high speed. It can meet the requirements of transmission and high stability. In addition, the power supply segment can be directly coupled to a predetermined contact on the circuit board by a power cable, external power can be obtained from the power input receptacle, and a power switch can be coupled to the power cable to switch the power supply. , Power on / off can be controlled. Furthermore, the circuit board of the present invention may combine the first and second display devices, and display the access status and power on / off status of the storage device.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the SATA interface module according to an embodiment of the present invention is configured by combining an adapter 1 and a circuit board 2. The adapter 1 is provided with a connector for a signal segment 11a and a power supply segment 12a that protrudes inward and conforms to a SATA standard pin. The signal segment 11a is connected to the signal cable 11b on the other side, or a signal receptacle 11d is provided so that the signal plug 11e at one end of the signal cable 11b can be fitted. The signal connector 11c at the other end of the signal cable 11b is fitted and connected to a host, an interface card or a signal port of a computer. Here, the advantage of adopting the signal receptacle 11d is that the adapter 1 does not have to be accompanied by a long signal cable 11b. The power cable 12b coupled to the other side of the power segment 12a is directly coupled and, for example, soldered to the circuit board 2 described later.

  The adapter 1 is provided with connecting portions 13 on both sides thereof so that a known connecting member can be used like an ear, and a member such as a screw or a bolt is passed through the hole 13a and fixed to a removable device or an external device. It can be installed.

  The circuit board 2 is provided with a power input receptacle 21 on the outside thereof, and is connected to a power supply connector of a power supply or a rectifier transformer to obtain external power. The power input receptacle 21 is coupled to the power switch 23 by, for example, a lead 22 or the like by wiring to form a control circuit. The power cable 12b is directly coupled and soldered to a predetermined contact on the circuit board 2, for example, so that the power segment 12a can obtain power. The adapter 1 and the circuit board 2 are connected by a power cable 12b, thereby forming a module. The circuit arrangement of the circuit board 2 is the same as that shown in “SATA mobile rack with power control” [Patent Document 1], and the circuit block or circuit diagram is not described here. Therefore, by switching the power switch 23, the power on / off of the power segment 12a can be controlled, the removable device or the external device can be hot swapped, and the storage device safety appeal can be met.

  In addition, the circuit board 2 is connected to the first display device 25 such as an LED lamp by wiring, for example, by a lead 24 to form a circuit, and when it is lit, it accesses the storage device in the removable device or the external device. Is expressed. Further, the circuit board 2 forms a circuit by connecting the lead 26 to a second display device 27 such as an LED lamp by another wiring, for example, indicating that it is in a power conduction state when turned on, and is in a disconnected state when turned off. It expresses that there is.

  Further, the circuit board 2 is separately provided with a fan power receptacle 28 on the inner side thereof, so that the required power of the fan fixed to the removable device or the external device can be supplied to dissipate heat.

  As shown in FIG. 2 and FIG. 3, in the operation of the SATA interface module to the removable device, the removable device is composed of an outer casing 3 and an inner casing 4. The outer casing 3 is a hollow frame and is installed and installed in the installation space of the computer host. The dimension of the frame chamber 31 can be inserted or removed corresponding to the dimension of the inner casing 4. The adapter 1 is fixed to the back plate 32 of the outer casing 3 corresponding to the port 41 on the back of the inner casing 4, and the circuit board 2 is also fixed to the rear panel 32. The power switch 23, the first display device 25 and the second display device 27 are extended to the front of the outer casing 3 with leads so that they can be controlled and displayed.

  The inner housing 4 accommodates a SATA interface storage device such as a hard disk. Further, the port 41 on the back surface of the inner housing 4 is configured so that the signal segment 11a and the power supply segment 12a of the adapter 1 can be coupled and separated.

  In view of the above-described embodiments, the SATA interface module can also be used in an external device. For example, a hard disk external box with a SATA interface can be provided with a power control function.
