Description of drawings
Fig. 1 is the cable structure schematic diagram among the cable embodiment of the utility model transmission USB and digital visual interface signal;
Fig. 2 is the structural representation of combined interface among the described embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
As shown in Figure 1, in the cable embodiment of the utility model transmission USB and digital visual interface signal, cable 1 comprises the secondary signal line 19 that is used to transmit first holding wire 18 of universal serial bus signal and is used for the transmission digital video interface signal, in the present embodiment, above-mentioned first holding wire 18 and secondary signal line 19 are insulated layer (not marking among Fig. 1) and are surrounded as one, first holding wire, 18 two ends connect serial bus interface, and secondary signal line 19 two ends connect digital visual interface.In this enforcement, the digital visual interface that above-mentioned secondary signal line two ends connect is DVI interface 11 shown in Fig. 1 and the 2nd DVI interface 12; Wherein a DVI interface 11 is combined interfaces, wherein existing digital visual interface is USB also, with regard to present embodiment, this combined interface is a dual signal interface that is similar to the DVI-I structure, be that its profile is the DVI-I in the digital visual interface, and the analog signal line among the digital visual interface be changed to the DVI-Integrated of USB (universal serial bus) holding wire (i.e. first holding wire 18).At the other end of cable 1, what secondary signal line 19 connected is an independent DVI-Digital, and 18 connections of first holding wire is an independent USB plug 13; At this other end, because first holding wire 18 has been connected independently interface (being plug) respectively with secondary signal line 19, also being provided with above-mentioned first holding wire 18 and secondary signal line 19 on this end is the breakout 14 that separates separately by the state-transition of being bundled together by above-mentioned insulating barrier, and breakout 14 is divided into two DVI holding wire (secondary signal line 19) and usb signal line (first holding wire 18).
In the present embodiment, as mentioned above, a DVI interface 11, on one side of cable 1, its DVI digital signal is identical with general DVI digital signal, and its original analog signal interface changes the usb signal interface into, is used to connect the desktop monitor that has DVI and USB interface; The 2nd DVI interface 12, at the another side of cable 1, its DVI digital signal is identical with general DVI digital signal, and its original analog signal interface is vacant, is used to connect the DVI mouth of computer; USB plug 13, at the cable another side, with described the 2nd DVI plug 12 side by side and be separated from each other, be used to connect USB interface of computer.
In the present embodiment, also have first magnet ring 15 and second magnet ring 16 on the cable 1.Described first magnet ring 15 is USB cable shielding magnet ring, and it is positioned on first holding wire 18 that breakout 14 tells, and it is near USB plug 13 and surround first holding wire 18; Second magnet ring 16 is a DVI cable shield magnet ring, and it is positioned at the end that cable 1 connects combined interface (i.e. a DVI interface 11), near this combined interface, and surrounds connection parallel first holding wire 18 and secondary signal line 19.The effect of above-mentioned magnet ring is the external radio frequency interference of short-circuit signal line and cuts the interference of external radio-frequency signal to transmission signals.Do not have magnet ring, the phenomenons such as twill, ripples line that perhaps have external disturbance occur.
Further, the configuration signal of the signal pin of an above-mentioned DVI plug 11 (being combined interface) is seen and is comprised Fig. 2: DVI pin configurations 131 and USB pin configurations 132, and wherein: DVI pin configurations 131 disposes identical with general DVI signal pin; USB pin configurations 132 is that the analog signal pin configurations with original DVI plug changes the usb signal pin configurations into, be used to connect therewith corresponding, desktop monitor with identical DVI and USB dual signal socket, its pin signal are four signals of standard USB, are followed successively by power supply V
BUS, differential data line D-, D+ and ground GND.Other end connection usb 13 at first holding wire 18 is the USB public access mouth of 4PIN, and its pin signal also is a standard.
In the present embodiment, cable 1 also is provided with the screen (not shown) that is used for shielding respectively described first holding wire 18 and secondary signal line 19, and screen lays respectively between first holding wire 18, secondary signal line 19 and the insulating barrier.Because cable 1 includes DVI holding wire and usb signal line and parallel simultaneously longer distance, the setting of above-mentioned screen can effectively guard against mutual signal to disturb.
In other embodiment of the utility model, different interface connected modes also can be arranged, for example, can be all to be set to an above-mentioned DVI interface 11 or other forms of combined interface at the two ends of cable 1, also can all be set to the various DVI interfaces and the USB interface of separating at the two ends of cable 1, certainly, the concrete condition of this equipment that need connect on this cable is decided.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
