Abstract
The utility model relates to a high-definition audio-video cable. The high-definition audio-video cable comprises an external coating layer, a subline, an earth wire and a woven layer, where the subline and the earth wire are arranged in the external coating layer; the subline comprises a single-core wire and a multi-core wire; and the woven layer is arranged in the external coating layer and is coated orderly along the linear length direction of the subline. According to the high-definition audio-video cable, one cable contains all HD (High-Definition) videos and audios, and thus, a cumbersome working procedure of twisting wires is avoided, the processing cost is lowered, the production efficiency is improved, the digital property of video and audio signals from an output device to a display device can be kept, the cable supports the connection among various high-definition devices, and the complexity of wire arrangement is also lowered.
Description
Technical field
The utility model relates to a kind of connecting line, particularly a kind of high resolution audio and video line.
Background technology
High resolution audio and video, namely HDMI (High Definition Multimedia Interface) also is in the abbreviation of High Definition Multimedia Interface.High resolution audio and video is along with Digital Television, HDTV (High-Definition Television) and panel TV rise and a kind of new interface of appearance, is the product of digital Age fully.The high resolution audio and video line is applied to generally that transfer of data is connected between HDTV (High-Definition Television) and DVD, the VCD.Before the high resolution audio and video standard was announced, digital video and audio interface were separated, and video interface is DVI.The volume of comparing the high resolution audio and video interface with DVI is less, and can while transmission of audio and vision signal.The length of cable of DVI can not surpass 8 meters, otherwise will affect image quality.Another kind of connecting line needs three connecting lines of RGB, needs during use according to the corresponding connector that connects audio frequency, video of color, usage comparison trouble.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of loaded down with trivial details operation that can avoid twisted wire is provided, and cuts down finished cost, and has improved the high resolution audio and video line of production efficiency.
The technical scheme that realizes the utility model purpose is: a kind of high resolution audio and video line has serving and is arranged on serving interior sub-line and ground wire; Described sub-line has single-core line and split conductor; Also has braid; Described braid is arranged in the serving, and carries over the line body length direction coating of sub-line.
The described sub-line of technique scheme has 5 split conductors and 4 single-core lines; Described 5 split conductor annular arrays arrange; Described 4 single-core lines are arranged on the periphery of 5 split conductors.
The described split conductor of technique scheme have insulating barrier and be arranged in the insulating barrier one group mutually stranded single-core line line to a little ground wire.
The described serving of technique scheme is the PVC plastics.
After adopting technique scheme, the utlity model has following positive effect:
(1) the utility model comprises all HD Audio and Videos in a cable, avoids the loaded down with trivial details operation of twisted wire, cuts down finished cost, improved production efficiency, video and audio signal keeps numerical from the output equipment to the display device, support multiple high definition device to connect, and also reduces the wiring complexity.
(2) centre distance is relatively stable between sub-line of the present utility model, and length is relatively consistent, and the synchronism of signal transmission is good, and impedance stabilization can be obtained higher Voice ﹠ Video transmission quality.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is cross section structure schematic diagram of the present utility model;
1. servings among the figure, 2. sub-line, 21. single-core lines, 22. split conductors, 221. insulating barriers, 222. little ground wires, 3. braid, 4. ground wire.
Embodiment
(embodiment 1)
See Fig. 1, the utlity model has serving 1 and be arranged on sub-line 2 and ground wire 4 in the serving 1; Serving 1 is the PVC plastics, and sub-line 2 has 5 split conductors 22 and 4 single-core lines 21; Described 5 split conductors, 22 annular array settings; 4 single-core lines 21 are arranged on the periphery of 5 split conductors 22, wherein split conductor 22 have insulating barrier 221 and be arranged in the insulating barrier 221 one group mutually stranded single-core line line to a little ground wire 222; Also has braid 3; Braid 3 is arranged in the serving 1, and carries over the line body length direction coating of sub-line 2.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
