Abstract
The invention relates to a signal transmission line, in particular to a digital signal transmission line with a good using effect. The digital signal transmission line comprises signal wires which are formed by combining two core wires and a ground wire and wrapping with an inner shielding layer, and is characterized in that: the four signal wires are wrapped with double-side wing aluminum foil mylar to form a shielding layer and then combined with a common ground wire and wrapped with an outer shielding layer; and a PVC (polyvinyl chloride) jacket layer is formed on the outer shielding layer. The invention has the advantages of environmental friendliness, material saving, stable impedance, strong crosstalk isolation ability, low signal loss, long service life, little signal transmission interference, more stable signal transmission, good using effect and the like.
Description
Technical field:
The present invention relates to signal transmssion line, the digital data transmission line that specifically a kind of result of use is good.
Background technology:
As everyone knows, the DiiVA interface realizes passing through Digital Television, connect, configuration, various consumer electronic devices such as set-top box in the control man, computer, video disc player, game machine, video camera, sound equipment etc., and form based on individual field content and share and use, home network with Internet connection, allowing connect operates easier with use, create best entertainment effect simultaneously, realize that easily any content shows on any apparatus, simultaneously to high resolution audio and video, USB, Ethernet and device control command, the trend that meets the current network fusion development, in order to satisfy the ever-increasing demand of TV load bearing equipment, at present, each big TV manufacturer of the whole world is in the design type, have to add outfit interface as much as possible, comprise the TV terminal, the AV interface, the USB2.0 interface, the VGA interface, multiple external-connected ports such as earphone interface and HDMI digital high-definition interface, every kind of outer end interface all needs to dispose a kind of signal transmssion line, existing signal transmssion line is earlier with after two heart yearns and the earth connection combination, adopt internal shield to be rolled into holding wire, requirement according to every kind of external equipment becomes signal transmssion line with at least two holding wires with earth connection or other lead combination back parcel outer shielding layer with restrictive coating then, internal shield adopts the single face aluminium foil, external shield adopts aluminium foil and conductive wire braiding to form, restrictive coating adopts plastic pvc to make, the television set interface is many more, the kind that means signal transmssion line is many more, cause its cost high more, the stand also will be many more to consumer's expense.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide that a kind of loss of signal of adopting environment-friendly materials to make is little, the multifunctional digital signal transmssion line of long service life, steady signal transmission.
The present invention can reach by following measure:
A kind of digital data transmission line, comprise by after two heart yearns and the earth connection combination, the holding wire that adopts internal shield to be rolled into, it is characterized in that it is screen that four holding wires draw parcel by the two-sided aluminium foil wheat that spreads the wings, be enclosed with outer shielding layer again with after the shared earth connection combination, outer shielding layer is provided with the PVC restrictive coating.
Outer shielding layer of the present invention adopts the two-sided aluminium foil wheat that spreads the wings to draw and conductive wire braiding composition, to improve strong, the low loss of isolation cross-talk ability, increases its useful life.
The present invention has been owing to adopted said structure, have environmental protection material-saving, Impedance stable, isolate that the cross-talk ability is strong, low loss, long service life, transmission signal disturb little, advantage such as transmission signals is more stable, result of use is good.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As shown in drawings, a kind of digital data transmission line, comprise by after two heart yearns 1 and earth connection 2 combinations, the holding wire that adopts internal shield 3 to be rolled into, above-mentioned same as the prior art, this does not give unnecessary details, the invention is characterized in that it is screen 7 that four holding wires draw parcel by the two-sided aluminium foil wheat that spreads the wings, be enclosed with outer shielding layer 5 again with after shared earth connection 4 combinations, outer shielding layer adopts the two-sided aluminium foil wheat that spreads the wings to draw and conductive wire braiding composition, outer shielding layer 5 is provided with PVC restrictive coating 6, of the present inventionly draw for the two-sided aluminium foil wheat that spreads the wings, restrictive coating of the present invention is PVC or Halogen material, and the environmental protection material-saving is arranged, Impedance is stable, it is strong to isolate the cross-talk ability, low loss, long service life, advantages such as it is little to transmit the signal interference, and transmission signals is more stable.
Claims (2)
1. digital data transmission line, comprise by after two heart yearns and the earth connection combination, the holding wire that adopts internal shield to be rolled into, it is characterized in that it is screen that four holding wires draw parcel by the two-sided aluminium foil wheat that spreads the wings, be enclosed with outer shielding layer again with after the shared earth connection combination, outer shielding layer is provided with the PVC restrictive coating.
2. a kind of digital data transmission line according to claim 1 is characterized in that outer shielding layer adopts the two-sided aluminium foil wheat that spreads the wings to draw and conductive wire braiding composition.
