Description
Technical field
The utility model relates to power supply unit, particularly a kind of desktop computer pre-power supply accessory power outlet.
Background technology
At present, the ancillary equipment relevant with computer gets more and more, and computer user often needs often charge for other mini-plants or directly provide civil power for computer peripheral, and this makes original supply socket often not enough.At present, also do not have desktop computer can for user provides civil power in front panel, although present computer has devised usb data interface, the electric current of this interface have exported less, is difficult to meet user's needs.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of desktop computer pre-power supply accessory power outlet.
The purpose of this utility model is achieved through the following technical solutions:
A kind of desktop computer pre-power supply accessory power outlet, is made up of attaching plug, outer casing of power supply, panel, mains switch, described panel is provided with mains switch, commercial power socket and USB charging inlet; The height and the width of described outer casing of power supply are identical with the height and the width of desktop computer CD-ROM drive, can carry out installation and fix on desktop computer CD-ROM drive position; The outer casing of power supply be in place, its panel flushes with other panels before desktop computer.Described commercial power socket adopts the five hole plate connectors meeting socket new national standard standard, and output voltage is 220V; Described USB charging inlet is low-voltage charging inlet, and USB charging inlet 33 output voltage is 5V, more than output current 0.9A.
The utility model has the advantage of:
1) USB power source output interface can provide power supply for compact electric apparatus such as 2.5 cun of portable hard drives, also can be mobile phone quick charge, overcome the defect of common preposition usb data interface electricity shortage;
2) mains power socket can be the larger ancillary equipment such as 3.5 cun of portable hard drives and provides power supply, enables the power taking nearby of computer peripheral equipment;
3) carry out installation to fix in the preposition CD-ROM drive position of case for desktop computer, make use of the restricted quarter of desktop computer, and install and use all very convenient.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model
In figure: 10-attaching plug, 11-power line, 20-outer casing of power supply, 21-installation fixing hole, 30-panel, 31-mains switch, 32-commercial power socket, 33-USB charging inlet.
Embodiment
Below, the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
Fig. 1 is an embodiment of the present utility model.As shown in the figure, a kind of desktop computer pre-power supply accessory power outlet, is made up of attaching plug 10, outer casing of power supply 20, panel 30, mains switch 31, described panel 30 is provided with mains switch 31, commercial power socket 32 and USB charging inlet 33; The height and the width of described outer casing of power supply 20 are identical with the height and the width of desktop computer CD-ROM drive, install fixing hole 21 to match with the location hole on the preposition CD-ROM drive position in computer cabinet or groove, outer casing of power supply 20 can be fixed on desktop computer CD-ROM drive position.
The material of described panel 30 and the material of color and desktop computer front panel and color match, and the panel 30 be in place flushes with other panels before desktop computer and harmonious.
Described commercial power socket 32 adopts the five hole plate connectors meeting socket new national standard standard, and output voltage is 220V.
Described USB charging inlet 33 is low-voltage charging inlets, and USB charging inlet 33 output voltage is 5V, more than output current 0.9A.
Attaching plug 10 inserts commercial power socket power taking, is directly powered for commercial power socket 32 by power line 11; By rectification, filtering, then become high frequency by switching circuit, reduce voltage by high frequency transformer, after then rectification, filtering, export low-voltage DC, for USB charging inlet 33 provides power supply.
Mains switch 31 controls commercial power socket 32 and USB charging inlet 33 simultaneously.
Above-described embodiment of the present utility model is the exemplary embodiment for illustrating cited by the utility model, instead of to the restriction that execution mode of the present utility model is done.By the utility model embodiment prompting the obvious variation pattern of amplifying out be still in rights protection scope of the present utility model.
