Description
Technical field
The utility model relates to connection cables technical field, in particular to a kind of HDMI multi-media connecting cable.
Background technique
HDMI, full name in English are High Definition Multimedia Interface, and Chinese is high-resolution
The abbreviation of multimedia interface.HDMI can transmit uncompressed HD video and multichannel audb data, highest number in high quality
It is 48Gbps according to transmission speed.High-definition multi-media connecting line (abbreviation HDMI wire) is used primarily in DVD, PS3, digital TV in high resolution
High-definition digital signal is transmitted between base top box and digital TV in high resolution or display equipment.HDMI wire energy simultaneous transmission audio and view
Frequency signal.It is big that HDMI wire transmits flow, and all information are all that the form of digital signal is transmitted.Letter is allowed in this way
It number will not be distorted in transmission process.Since HDMI wire can integrate audio, video signal transmission, and weight small in size
Gently, good appearance, therefore it will gradually replace existing audio-video signal and VGA line and be widely used.
There are six different colors for 5 strands of signal wires tool in existing multi-media connecting cable, to distinguish wherein 5 strand
Enclose welded position.In addition, signal wire is more demanding to the consistency and stability of processing procedure, otherwise to the decaying of signal wire,
Delay difference, differential impedance have an impact in differential pair, but such multi-media connecting cable in process of production can be because of replacement
The wasting of resources caused by color, and efficiency is lower.
Utility model content
For above-mentioned defect existing in the prior art, the technical problem to be solved by the present invention is to provide a kind of HDMI
Multi-media connecting cable, solve multi-media connecting cable in the prior art will cause the cable wasting of resources in process of production, and
And the problem that efficiency is lower, production efficiency is higher, greatlys save cable resource, reduces production cost.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is:
A kind of HDMI multi-media connecting cable, including coil, electric wire and aluminium foil, the coil and electric wire are by Aluminium Foil Package
Wrap up in, winding layer be provided with outside the aluminium foil, be provided with sheath outside the winding layer, the coil include the first signal wire,
Second signal line, built-in ground wire, single side aluminium foil and transparent polyester film, the single side aluminium foil and transparent polyester film are by described
One signal wire, second signal line and built-in ground wire are bundled together, the color of first signal wire and the second signal line
Color it is different.
Preferably, the color per the first signal wire in one described coil is white, per one described coil in the
The color of binary signal line is green.
Preferably, the quantity of the coil is 5 strands, the mutual not phase of the color per the transparent polyester film in one described coil
Together.
Preferably, the HDMI multi-media connecting cable further includes external ground wire, the external ground wire be embedded in aluminium foil with
Between winding layer.
Preferably, the quantity of the electric wire is 4.
By adopting the above technical scheme, a kind of HDMI multi-media connecting cable provided by the utility model, the HDMI multimedia
First signal wire, second signal line and built-in ground wire are wrapped in one by single side aluminium foil and transparent polyester film in connection cables
Rise, and set different for the color of the color of first signal wire and second signal line, i.e., by by signal wire by
Six kinds of colors originally are changed to two kinds of colors, avoid the HDMI multi-media connecting cable cable in process of production because of replacement
The wasting of resources caused by signal line color, production efficiency is higher, and cable resource is greatly saved, reduces production cost.
Detailed description of the invention
Fig. 1 is a kind of cross section structure schematic diagram of HDMI multi-media connecting cable of the utility model；
In figure, 1- winding layer, 2- aluminium foil, 3- transparent polyester film, 4- single side aluminium foil, the first signal wire of 51-, 52- second
