Abstract
The utility model discloses a VGA distribution device. The VGA distribution device only comprises an input end. The input end comprises an audio input, a video input and a USB power supply input. In the utility model, the input end adopts one interface; an audio, a video and power supply are integrated on one wire without an external power supply; and the VGA distribution device obtains power from a computer mainframe (a laptop) by a USB. Therefore, the VGA distribution device is environment-friendly and energy-saving and saves cost and space.
Description
Technical field
The utility model relates to the dispenser technology field, particularly relates to a kind of VGA (VideoGraphic Array shows the drawing array) distributor.
Background technology
Existing VGA distributor has only the video input usually, and the audio frequency input is perhaps also arranged, but the audio frequency of input, video, three parts of powering are independently, difference lead-out wire on body, power supply needs other power supply adaptor, and body mostly is an iron-clad.
But distributor of the prior art because audio frequency, video, power supply three parts of input are independently assembled, makes cost waste, and installs complicated.
The utility model content
Problem to be solved in the utility model provides a kind of VGA distributor, and distributor needs a plurality of stand-alone interfaces, defect of high cost in the prior art to overcome.
For achieving the above object, the technical solution of the utility model provides a kind of VGA distributor, and described VGA distributor only comprises an input, and described input comprises audio frequency input, video input and USB power supply input.
Further, the input of described video comprises: red primary heart yearn, green primary heart yearn, blue primary heart yearn,, red ground heart yearn, heart yearn, blue ground heart yearn, the synchronous heart yearn of row and field synchronization heart yearn greenly.
Further, described audio frequency input comprises two heart yearns.
Further, described USB power supply input comprises an anodal heart yearn of power supply, and its negative pole is communicated with the signal ground of VGA.
Further, the shell of described VGA distributor adopts plastic housing.
Further, described VGA distributor also comprises the external direct current power supply input, is described VGA distributor power supply when being used to not have USB power supply or USB electricity shortage.
Further, the mainboard of described VGA distributor comprises power supply protection spacer assembly, is used for when connecing USB power supply and external direct current power supply simultaneously the two-way power supply being isolated.
Compared with prior art, the technical solution of the utility model has following advantage:
VGA distributor of the present utility model, input adopts an interface, and with audio frequency, video, power supply is integrated on the single line, need not external power source, and from host computer (notebook) power taking, environmental protection and energy saving are saved cost, conserve space by USB.
Description of drawings
Fig. 1 is the structural representation of a kind of VGA distributor of the utility model embodiment;
Fig. 2 is the structural representation of the another kind of VGA distributor of the utility model embodiment;
Fig. 3 is that a kind of VGA splitter interface of the utility model embodiment distributes schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
The VGA dispensing arrangement of the utility model embodiment and interface assignment schematic diagram as shown in figures 1 and 3, described a kind of VGA distributor only comprises an input, described input comprises audio frequency input, video input and USB power supply input, very conserve space.
The input of described video comprises: red primary heart yearn 1, green primary heart yearn 2, blue primary heart yearn 3, red ground heart yearn 6, heart yearn 7, blue ground heart yearn 8, the synchronous heart yearn 13 of row and field synchronization heart yearn 14 greenly.
Described audio frequency input comprises two heart yearns.
Described USB power supply input comprises an anodal heart yearn of power supply, and its negative pole is communicated with the signal ground of VGA.
The shell of described VGA distributor adopts plastic housing, light and beautiful.
Described VGA interface also comprise self-test 5, address code 4, digitally 10, address code 11, address code 12, address code 15 and keep position 9.
Described VGA distributor also comprises the external direct current power supply input, is described VGA distributor power supply when being used to not have USB power supply or USB electricity shortage, and its VGA distributor mainboard consumed power is very little, just can guarantee that distributor normally moves; Also reserve simultaneously and got well the DC joint, if do not have USB power supply or USB electricity shortage, can external one be output as: the power supply adaptor of DC9V 600mA, cost is saved in environmental protection and energy saving.
The another kind of structural representation of the VGA distributor of the utility model embodiment as shown in Figure 2, described distributor can external one be output as: DC9V, the power supply adaptor of 300mA.
The mainboard of described VGA distributor comprises power supply protection spacer assembly, is used for when connecing USB power supply and external direct current power supply simultaneously the two-way power supply being isolated; Make main frame energy operate as normal simultaneously, and be unlikely to burn out mainboard.
VGA distributor of the present utility model, input adopts an interface, and with audio frequency, video, power supply is integrated on the single line, need not external power source, and from host computer (notebook) power taking, environmental protection and energy saving are saved cost, conserve space by USB.
Described only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
