Abstract
The invention discloses a USB (Universal Signal Bus) high-frequency signal wire rod, comprising a coating layer arranged at the outermost layer and a braided fabric protective layer arranged inside in the coating layer, wherein the braided fabric layer is internally provided with two SDP (Session Description Protocol) signal pairs, a UTP (Unshielded Twisted Paired) signal pair and a power feeder; and the braided fabric protective layer is internally provided with a ground wire; the braided fabric protective layer is internally provided with filler. The USB high-frequency signal wire rod disclosed by the invention has the advantages of high transmission speed, good stability, good compatibility and wide application range and can be applied to the aspects such as an external hard disk, a high-resolution network camera, a video monitor, a video display, a digital camera with a USB port, a digital video, a bluray drive and the like.
Description
Technical field
The present invention relates to a kind of high-frequency signal wire rod, especially relate to a kind of USB high-frequency signal wire rod.
Background technology
USB is the abbreviation of English Universal Serial BUS (USB), and its Chinese is abbreviating " logical get lines crossed " as, is an external bus standard, is used for being connected and communication of standard computer and external equipment, is the interfacing that is applied in the PC field.The plug and play of USB interface support equipment and hot plug function.
But USB2.0 high-frequency signal wire rod version forward is because its limitation is bigger at present; The reader device the most frequently used like people; Especially in equipment, use polytype flash card simultaneously; Or card reader is connected on the USB Hub, and when a plurality of card reader was arranged on the USB Hub, the sort of transmission speed was very slow; Pass test data also can be learnt; The high-frequency signal wire rod differential impedance (Differential Impedance) of USB2.0 version is 90 Ω ± 7 Ω/200ps (cable); Transmission delay differences (Skew) is 15 ps/m (max); And decay (Attenuation), near-end lose (NEXT), long-range loss (NEXT), volume of transmitted data (Data Rate) all only greater than 5Gbps, and range of application is smaller, can not adapt to the requirement of modern product on speed.
Summary of the invention
It is fast that technical problem to be solved by this invention provides a kind of speed of service, and the USB high-frequency signal wire rod of good stability.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme.
This USB high-frequency signal wire rod comprises being arranged on outermost serving and the braid protective layer that is arranged in the serving, be provided with in the said braid protective layer SDP signal to, UTP signal to and supply lines.
In order to guarantee stable signal transmission, further, be provided with ground wire in the said braid protective layer.
In order to make USB high-frequency signal wire rod not influenced by extraneous vibration or other factors, more further, be provided with filler in the said braid protective layer.
In order to guarantee signaling rate, further, said SDP signal has two pairs to quantity.
Compared with prior art; Usefulness of the present invention is: this USB high-frequency signal wire rod signaling rate is fast; Good stability; Compatible good, range of application is also very wide, can be used in the aspects such as digital camera, DV and blu-ray drives of external hard disk, high-resolution IP Camera, video-frequency monitor, video display, USB interface.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of USB high-frequency signal of the present invention wire cross-section structural representation.
Among the figure: 1, serving; 2, braid protective layer; 3, the SDP signal is right; 4, ground wire;
5, supply lines; 6, filler; 7, the UTP signal is right.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of USB high-frequency signal wire rod shown in Figure 1 comprises being arranged on outermost serving 1 and the braid protective layer 2 that is arranged in the serving 1, and braid protective layer 2 can be used for the guard signal wire rod and be difficult for impaired; Be provided with in the said braid protective layer 2 two pairs of SDP signals to 3, a pair of UTP signal is to 7 and a pair of supply lines 5; Can be to the transmission speed of raising signal with the UTP signal through the SDP signal to 7 to 3,5 of supply lines are to be used for power supply; In order to guarantee the stability of signal transmission, be provided with ground wire 4 in the said braid protective layer 2; In order to make USB high-frequency signal wire rod not influenced by extraneous vibration or other factors, be provided with filler 6 in the said braid protective layer 2; USB high-frequency signal wire rod has the backward compatibility standard, and has the function of traditional USB technology proximities and plug and play (Plug and Play) concurrently.The target of USB high-frequency signal wire rod technology is to release than the fast product more than 10 times of present connection level, and the employing framework identical with wired USB; And support Optical Fiber Transmission environment backward; USB high-frequency signal wire rod standard is supported light and two kinds of interface medium of copper, length of cable and transmission speed also can so and different.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
