Abstract
The utility model relates to a high-definition fiber transmission device powered by a USB (universal serial bus), which comprises a sending module, a receiving module, an optical fiber and two USB data cables or USB power cords; USB interfaces are formed on panels of the sending module and the receiving module; the sending module is connected with the receiving module through the optical fiber; and the sending/receiving module is connected with a USB interface of a display source end/display terminal through the USB data cables or the USB power cords. The utility model effectively meets the requirement for power supply of the modules, and selects the common USB interface with small volume, portability and convenient use in the electronic products, and has remarkable advantages in cost and appearance compared with the traditional external power.
Description
Technical field
The utility model relates to consumer electronics and large-scale demonstration engineering field, particularly a kind of high definition fiber transmission device with the USB power supply.
Background technology
Present USB technology makes the various external equipments that can discern automatically connect with computer, and loads driver voluntarily to move new device.And one insert the i.e. device of usefulness, and the USB interface that needs power supply is mostly carried out transfer of data and power supply is provided.Power supply is obtained the required power supply of functional module by the power pin of USB connector.USB is packaged with standard Type A at present, and three types of Type B and mini USB can select suitable encapsulation according to demand.
High-definition media interface has a variety of at present, such as HDMI, DVI etc., the short-range powerup issue of high definition cable series products is resolved at present, can pass to display terminal by the demonstration source by copper cable with the power supply of interior high definition cable for 45 meters, several solutions be arranged at present, wherein entirely in the Optical Fiber Transmission scheme greater than the high definition cable of 45 meters long distances, the power supply of transceiver module must all be powered by external power supply, external power supply generally has adapter, and volume is big, is inconvenient to carry and use.
Summary of the invention
The purpose of this utility model is in order to overcome problem and the shortcoming that above-mentioned prior art exists, a kind of high definition fiber transmission device with the USB power supply is provided, has solved the demand of module for power supply effectively, select common USB interface in the consumer electronics, volume is small and exquisite, and is convenient for carrying and uses; From cost with compared with traditional external power supply remarkable advantages is arranged all in appearance.
The purpose of this utility model can realize by following technical proposals:
A kind of high definition fiber transmission device with the USB power supply, form by sending module, receiver module, optical fiber, two usb data lines or USB power line, it is characterized in that: on the panel of sending module, receiver module, all be provided with USB interface, connect with optical fiber between sending module, the receiver module, sending module/receiver module is connected with the USB interface that shows source end/display terminal by usb data line or USB power line respectively.
The USB interface of sending module, receiver module can adopt the general encapsulation model of USB, as TypeA, Type B or mini USB encapsulation, specifically decides according to the actual look size.
The utlity model has following advantage: the demand that has solved module for power supply effectively; Select common USB interface in the consumer electronics, volume is small and exquisite, and is convenient for carrying and uses; From cost with compared with traditional external power supply remarkable advantages is arranged all in appearance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure: be usb data line or USB power line.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is with external power source special adapter cancellation, the utility model is made up of sending module, receiver module, optical fiber, two usb data lines or USB power line, on the panel of sending module, receiver module, all be provided with USB interface, connect with optical fiber between sending module, the receiver module, sending module links to each other with showing the source end by usb data line or USB power line, and receiver module is connected with the USB interface of display terminal by usb data line or USB power line.Compared with prior art, owing to cancelled the power source special adapter, it is safe in utilization convenient to have, plug wire advantage such as neat attractive in appearance.
Can be according to the demand of actual high definition optical transmission, the USB interface of sending module, receiver module adopts Type A, Type B and mini USB encapsulation.
Adopting the utility model to replace external power supply is sending module and receiver module power supply, becomes sending module, the required supply power voltage of inner each device of receiver module through voltage transitions by usb data line or USB power line again from the 5V voltage that demonstration source end/display terminal is provided.Because consumption electronic product is such as computer at present, therefore LCD, projecting apparatus, DVD etc. have 1 to 2 USB interface at least, select the utility model to pass through power supply and can save volume and cost, in addition as the user of consumer electronics, the utility model volume is small and exquisite, is convenient for carrying and uses.Demonstration source end is generally equipment such as host computer, blue-ray DVD, high definition player, PS3, and these equipment show all have 1 to 2 USB interface by statistics, therefore in use, can adopt idle USB interface power supply.
Usually can offer the supply pin of the voltage of sending module TX 5V owing to show the source end by USB interface, but display terminal generally can not provide power supply, therefore the receiver module RX that is connected with terminal must use external power supply to power, and the utility model then adopts novel USB powering mode in this field of high letter out connecting line.
Claims (2)
