Abstract
The utility model discloses a cable device for HDMI digital signal transmission. The cable device comprises an outer protection layer, an aluminum Myla, an anti-electromagnetic interference winding layer, electromagnetic shielding core wires and single core wires, wherein the four single core wires are enwrapped by the ten electromagnetic shielding core wires, the ten electromagnetic shielding core wires are enwrapped by the anti-electromagnetic interference winding layer, the anti-electromagnetic interference winding layer is enwrapped by the aluminum Myla, the aluminum Myla is enwrapped by the outer protection layer, the electromagnetic shielding core wire is formed by a conduction wire, a tinned copper braided tape and a PET belt, the conduction wire is coated with the tinned copper braided tape, and the tinned copper braided tape is coated with the PET belt. The cable device has the following advantages that each conduction wire is subjected to electromagnetic shielding to become the core wire for signal transmission, so that the plurality of core wires are bundled with more flexibility, and the area of the cross section is reduced; the common ground wires are not needed, the ground function is performed by the tinned copper braided tape, and furthermore the cost is reduced; the core wires are arranged in parallel, but not pair-twisted like the traditional way, so as to facilitate to balance the length of each wire, and reduce the impedance mismatch.
Description
Technical field
The utility model belongs to the equipment technical field of carry high frequency wideband digital signal, is specifically related to a kind of cable installation of HDMI digital data transmission.
Background technology
HDMI (High-Definition Multimedia Interface, high-definition multimedia digital data transmission interface) be widely used in the multimedia television audio-visual devices, carry high frequency wideband digital signal simultaneously, comprising signal of video signal, voice signal, network signal, compact conformation is just arranged, anti-interference, the characteristics of high-frequency wideband.Along with the acceleration of digital multimedia TV is universal, the HDMI cable installation, as a kind of equipment of carry high frequency wideband digital signal, is more and more used.For the heart yearn to the signal transmission carries out electromagnetic shielding, generally by a pair of signal core line pair twist together, then coated outside tin-coated copper braid over braid and PET are with, after the heart yearn pair twist, it is large that size becomes, and causes the multi cord boundling to produce a large amount of spaces later, and finally cause the chap of HDMI device, cause cost to increase, and reduce the good experience that the user uses.
As can be seen here, still there is defect in above-mentioned existing HDMI cable installation, and is urgently improved.
Summary of the invention
The shortcoming existed in using for existing HDMI cable, the utility model provides a kind of cable installation of HDMI digital data transmission, is applied to the high-definition multimedia digital data transmission, has solved the problem that needs additional magnet ring.
The utility model is to realize like this, a kind of cable installation of HDMI digital data transmission, by outer jacket, aluminium foil wheat draw, anti-electromagnetic interference winding layer, electromagnetic shielding heart yearn and single-core line form, article ten, the electromagnetic shielding heart yearn is around surrounding four single-core lines, ten electromagnetic shielding heart yearns of anti-electromagnetic interference winding layer parcel, the aluminium foil wheat is drawn the anti-electromagnetic interference winding layer of parcel, outer jacket parcel aluminium foil draws by wheat, the electromagnetic shielding heart yearn is comprised of wire, tin-coated copper braid over braid and PET band, tin-coated copper braid over braid parcel wire, PET band parcel tin-coated copper braid over braid.
What better, electromagnetic shielding heart yearn and single-core line were non-pair twist is arranged in parallel.
Better, wire is comprised of metal core wire and plastic layer.
Advantage of the present utility model is: often the heart yearn that electromagnetic shielding is treated as transmitting signal is all carried out in one wire outside, when making multiply heart yearn boundling, has more flexibility, has reduced cross-sectional area; Cancelled earth connection commonly used, grounding function weaves and brings realization by tin-coated copper, and then has reduced cost; Each burst of parallel placement of heart yearn, rather than traditional pair twist, be conducive to the length of balanced each strand like this, falls low-impedancely not mate.
The accompanying drawing explanation
Fig. 1 is the cross sectional representation of embodiment of the present utility model.
Fig. 2 is the cross sectional representation of the electromagnetic shielding heart yearn of embodiment of the present utility model.
Accompanying drawing explanation: 1, outer jacket; 2, the aluminium foil wheat is drawn; 3, anti-electromagnetic interference winding layer; 4, electromagnetic shielding heart yearn; 5, single-core line; 6, metal core wire, 7, plastic layer; 8, tin-coated copper braid over braid; 9, PET band.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with above-mentioned drawings and Examples, the utility model is described in further detail.
With reference to figure 1 and Fig. 2, a kind of cable installation of HDMI digital data transmission, by outer jacket 1, aluminium foil wheat draw 2, anti-electromagnetic interference winding layer 3, electromagnetic shielding heart yearn 4 and single-core line 5 form, article ten, electromagnetic shielding heart yearn 4 is around surrounding four single-core lines 5, ten electromagnetic shielding heart yearns 4 of anti-electromagnetic interference winding layer 3 parcels, the aluminium foil wheat is drawn the anti-electromagnetic interference winding layer 3 of 2 parcel, outer jacket 1 parcel aluminium foil wheat draws 2, electromagnetic shielding heart yearn 4 is with 9 to form by wire, tin-coated copper braid over braid 8 and PET, tin-coated copper braid over braid 8 parcel wires, PET is with 9 parcel tin-coated copper braid over braids 8.What electromagnetic shielding heart yearn 4 and single-core line 5 were non-pair twist is arranged in parallel.Wire is comprised of metal core wire 6 and plastic layer 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; for example, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
