Abstract

The utility model discloses a power supply with an SATA interface, which belongs to a computer fitting. A structure of the utility model is composed of an SATA interface and a power supply line, wherein three positive 3.3 volts DC contact pins, three earth wire COM contact pins, three positive 5 volts DC contact pins, three earth wire COM contact pins and three positive 12 volts DC contact pins are orderly arranged on the SATA interface; the positive 3.3 volts DC contact pins are connected with 3.3 volts power supply lines, the earth wire COM contact pins are connected with power supply earth wires, the positive 5 volts DC contact pins are connected with positive 5 volts power supply lines and the positive 12 volts DC contact pins are connected with positive 12 volts power supply lines. The power supply with the SATA interface has the advantages of reasonable design, simple structure, convenient operation, etc.; thus, the SATA interface can be provided for a computer serial port hard disc without the requirement of an SATA switching joint.

Description

Power supply with SATA interface

1, technical field

The utility model relates to a kind of computer fittings, specifically a kind of power supply with SATA interface.

2, technical background

The employed hard-disk interface of computing machine generally adopts the Parallel ATA interface at present, but the maximum data transfer rate that the Parallel ATA interface is supported can not unrestrictedly improve, at any time the raising of CPU technology, network technology, the data rate of hard disk have become the bottleneck of restriction computing machine development.In order to address this problem, people have developed the hard disk that adopts serial ports to connect, and SATA adopts the serial ports connected mode, and the difference of comparing its maximum with conventional art is and can checks transfer instruction, if find wrong meeting automatic straightening, this has improved reliability of data transmission to a great extent.That serial line interface also has is simple in structure, support hot plug, the fast advantage of transfer rate.But present power supply is not supported the serial ports hard disk, and the SATA interface lacks 3.3 volts of supply voltages, need use the SATA adapter during actual the use.

3, summary of the invention

Technical assignment of the present utility model is at above weak point, provide a kind of simple in structure, cost is low, can be the power supply with SATA interface that the serial ports hard disk provides the SATA interface.

The technical scheme that its technical matters that solves the utility model adopts is: be disposed with three positive 3.3 volts of DC contact pins, three ground wire COM contact pins, three positive 5 volts of DC contact pins, three ground wire COM contact pins and three positive 12 volts of DC contact pins on the SATA interface; Positive 3.3 volts of DC contact pins link to each other with 3.3 volts of power leads, and ground wire COM contact pin links to each other with power ground, and positive 5 volts of DC contact pins link to each other with positive 5 volts of power leads, and positive 12 volts of DC contact pins link to each other with positive 12 volts of power leads.

The power supply of the SATA of having interface of the present utility model is compared with prior art, have reasonable in design, simple in structure, easy to use, characteristics such as SATA interface can be provided for the serial ports of computers hard disk, thereby, have good value for applications.

4, description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is the structural representation with power supply of SATA interface;

Accompanying drawing 2 is for having the side view of SATA interface.

5, embodiment

With reference to explaining below the power supply work of Figure of description to the SATA of having interface of the present utility model.

Power supply with SATA interface of the present utility model, its structure is made of SATA interface 7 and power lead, is disposed with three positive 3.3 volts of DC contact pins 1, three ground wire COM contact pins 4, three positive 5 volts of DC contact pins 2, three ground wire COM contact pins 4 and three positive 12 volts of DC contact pins 3 on the SATA interface 7; Positive 3.3 volts of DC contact pins 1 link to each other with 3.3 volts of power leads 5, and ground wire COM contact pin 4 links to each other with power ground 6, and positive 5 volts of DC contact pins 2 link to each other with positive 5 volts of power leads 9, and positive 12 volts of DC contact pins 3 link to each other with positive 12 volts of power leads 8.

Only corresponding interface on the SATA interface 7 insertion serial ports hard disks of the present utility model need be got final product during use, save the trouble of using the SATA adapter.

Its processing and fabricating of power supply with SATA interface of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.

Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.

Claims

1, the power supply that has the SATA interface, comprise SATA interface and power lead, it is characterized in that being disposed with on the SATA interface three positive 3.3 volts of DC contact pins, three ground wire COM contact pins, three positive 5 volts of DC contact pins, three ground wire COM contact pins and three positive 12 volts of DC contact pins; Positive 3.3 volts of DC contact pins link to each other with 3.3 volts of power leads, and ground wire COM contact pin links to each other with power ground, and positive 5 volts of DC contact pins link to each other with positive 5 volts of power leads, and positive 12 volts of DC contact pins link to each other with positive 12 volts of power leads.
