Abstract

The utility model discloses a DOM of an SATA interface, which comprises a PCB (Printed Circuit Board), a main control chip, an NAND FLASH chip, a 7PIN in-line SATA base and a 2 PIN mounting power socket, wherein the 7 PIN in-line SATA base is vertically welded on the back surface of the PCB; and the main control chip, the NADA FLASH chip, and the 2pin mounting power socket are welded on the front of the PCB. The DOM of the SATA interface also comprises a 2*2 PIN in-line power socket, and the 2*2 PIN in-line power socket is vertically welded on the back surface of the PCB. The 7PIN is adopted in the SATA base, the power socket adopts 2*2 PIN and is vertically welded on the PCB of the SATADOM, thus the SATA DOM can be arranged in the main engine PCB in parallel, and the space of the main engine PCB and a shell is saved.

Description

A kind of DOM electric board of SATA interface

[technical field]

The utility model belongs to the computer hardware technology field, and being specifically related to a kind of is the DOM electric board that is used to store the SATA interface of data.

[background technology]

SATA is the abbreviation of Serial ATA, i.e. serial ATA.This is a kind of novel hard-disk interface type that is different from Parallel ATA fully, owing to adopting serial mode transmission data to gain the name.The SATA bus is used embedded clock signal; Possessed stronger error correcting capability; Be and check transfer instruction (being not only data) that if find wrong meeting automatic straightening, this had improved reliability of data transmission to a great extent with compare its maximum difference in the past.That serial line interface also has is simple in structure, support the advantage of hot plug.The SATA interface be the main flow interface of present computing machine.

DOM electric board and SSD (solid state hard disc) are owing to have characteristics such as antidetonation, noiseless, low-power consumption, stable performance; Replace the trend of mechanical hard disk more and more obvious, widespread use is military, industrial, medical, financial, vehicle-mounted, reach quiet demanding occasion or field.

Fig. 1 and Fig. 2 are respectively the SSD solid state hard discs of the SATA interface of 2.5 inches of the prior art standard form and 1.8 inches, and 11 is the public connectors of 7+15PIN SATA among the figure, and 12 is the screw fixed orifice.Its shortcoming is: because of area bigger; If the 7+15PIN SATA that directly installs on the mainboard connects on the slot, and fixes with screw, just must abdicate some areas on its main frame pcb board; Thereby can not weld other component devices and chip; Add the area occupied of screw hole and 7+15PIN SATA seat, will increase the size of host PC B printed board like this, thereby increase the volume of main frame.As if the SSD solid state hard disc (or DOM electric board) that fixes 2.5 inches and 1.8 inches SATA interfaces of standard form with fixed mount, except increasing SATA and power supply transfer line, also can increase the space and the volume of main frame.

[utility model content]

The utility model technical matters to be solved is to provide a kind of DOM electric board that can save the SATA interface of main frame pcb board and enclosure space.

The utility model adopts following technical scheme to solve the problems of the technologies described above:

A kind of DOM electric board of SATA interface comprises PCB printed panel, main control chip, NANDFLASH chip, 7PIN straight cutting SATA seat, the supply socket of 2PIN Surface Mount; Said 7PIN straight cutting SATA seat is vertically welded in the back side of said PCB printed panel; Said main control chip, NAND FLASH chip, the supply socket of 2PIN Surface Mount are welded on the front of said PCB printed panel.

Preferably, also comprise a 2*2PIN straight cutting supply socket, this 2*2PIN straight cutting supply socket is vertically welded in the back side of said PCB printed panel.

The advantage of the utility model is: the SATA seat of the utility model adopts 7PIN's; Supply socket is adopted 2*2PIN's; Vertical welding makes SATA DOM electric board just can parallelly be contained on the main frame pcb board on the pcb board of SATA DOM electric board like this, saves the space of main frame pcb board and casing.Removing under the power socket situation of 2*2PIN straight cutting; Can the external power supply patchcord 2PIN supply socket to the SATA DOM electric board PCB printed panel; Corresponding main frame pcb board can be economized out more space; Under this mode, this SATA DOM electric board goes on the more OEM mainboard.

[description of drawings]

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

The structural representation of the SSD solid state hard disc of 2.5 inches SATA interfaces of Fig. 1 prior art standard form.

The structural representation of the SSD solid state hard disc of 1.8 inches SATA interfaces of Fig. 2 prior art standard form.

Fig. 3 is the utility model structural representation.

Fig. 4 is the structural representation after the utility model is assemblied on the mainboard.

[embodiment]

As shown in Figure 3, a kind of DOM electric board 30 of SATA interface comprises PCB printed panel 31, main control chip 32, NAND FLASH chip 33,7PIN straight cutting SATA seat 34,2*2PIN straight cutting supply socket 35,2PIN Surface Mount supply socket 36; Said 7PIN straight cutting SATA seat 34 and 2*2PIN straight cutting supply socket 35 are vertically welded in the back side of said PCB printed panel 31; Said main control chip 32, NAND FLASH chip 33,2PIN Surface Mount supply socket 36 are welded on the front of said PCB printed panel 31.

In another embodiment; Remove under the situation of power socket 35 of 2*2PIN straight cutting; Can the external power supply patchcord in the 2PIN Surface Mount supply socket 36 to the DOM electric board PCB printed panel 31; Corresponding main frame pcb board can be economized out more space, and under this mode, this DOM electric board goes on the more OEM mainboard.

DOM electric board 30 just can parallelly be contained on the main frame pcb board, save the space of main frame pcb board and casing.As shown in Figure 4.Can let DOM electric board 30 parallel being assemblied on the machine PCB mainboard 20 of SATA interface; Because 7PIN straight cutting SATA seat 34 is little with 2*2PIN straight cutting supply socket 35 areas occupied; Add the pcb board 20 of these SATA DOM electric board 30 belows and can also lay a plurality of components and parts 21; Save the area of host PC B mainboard 20, thereby reached the purpose of the volume that reduces machine.And increase 2PIN Surface Mount supply socket 36 in addition; To some OEM mainboards; Can not use 2*2PIN straight cutting supply socket 35 according to the concrete condition of the power output end position of machine, change and use 2 core power supply transfer lines to receive 2PIN Surface Mount supply socket 36; Thereby reach the effect of flexible use, reduce machine volume purpose thereby reach.

The utility model can reduce the size of main frame pcb board, can also compress the thickness of main frame, thereby reaches the effect that reduces the main frame volume.Compare and use 1.8 and 2.5 inches standard form SSD solid state hard disc or DOM electric board, can reduce the size of main frame pcb board, and save the fixed structure piece of SSD solid state hard disc, thereby reach the effect that reduces the main frame volume.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
