Abstract
A high frequency data transmission cable, which belongs to the cable technical field, comprises a cable core and an external sheath, wherein four pairs of foaming video signal wires, two groups of twisted pair wires and three individual audio electronic wires are arranged in the cable core, a comprehensive shielding layer and a polyester film taped covering are arranged outside the cable core, and the polyester film taped covering is arranged between the comprehensive shielding layer and the external sheath. The utility model has the advantages of reasonable structure, easy manufacturing and low cost. Each pair of foaming video signal wires is covered with an aluminum-plastic shielding tape, so as to prevent the mutual interference. The comprehensive shielding layer arranged outside the cable core greatly strengthens the interference proof performance thereof and guarantees the transmission of the data signal. The utility model can meet completely the requirement of high speed and large capacity transmission, and can be applied to fine definition multimedia interfaces. An environment friendly polyvinyl chloride sheath is adopted as the external sheath of the cable, the environmental protection performance of the material thereof meets the requirement of European ROHS environmental protection order. The cable has round appearance, excellent transmission performance, good shielding effect, and strong interference proof performance, is environment-friendly and clean, and is highly appraised by customers after the trial use.
Description
Technical field
The utility model relates to a kind of structure of data transmission cable, belongs to the cable technology field.
Background technology
Acceleration propelling along with the digitlization engineering, HD video, voice frequency electronics are more and more universal, requirement to data line is also more and more higher, and people to environmental protection ideas progressively deeply, the traditional data line can not satisfy the requirement of digitized video technology to high-resolution, high transfer rate, high color depth image and digital audio fully.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned traditional data line, provides a kind of outward appearance rounding, transmission performance excellent, the high-frequency data transmission cable that shield effectiveness is good.
The purpose of this utility model is to realize like this, the high-frequency data transmission cable, comprise cable core and oversheath, it is characterized in that being provided with in the described cable core four pairs of foaming video signal cable, two groups of twisted pair wires and three independent audio electronics lines, cable core is provided with comprehensive shielded layer and polyester film lapping layer outward, and the polyester film lapping layer is arranged between comprehensive shielded layer and the oversheath.
Every pair of video signal cables foaming of described four pairs of foaming video signal cable thoroughly does away with by two that wrapped plastic-aluminum mask tape constitutes on the stranded core of edge cores and box-like tin plated wire earth connection of multiply bundle, has at least one to thoroughly do away with the edge core and be provided with the color that is different from other insulated wire cores in every pair of foaming video signal cable.
Described comprehensive shielded layer is made of plastic-aluminum mask tape lapping layer and the close net braid of tin plated wire, and plastic-aluminum mask tape lapping layer is wrapped in the cable core periphery, and the close net braid of tin plated wire is woven on the lapping layer of plastic-aluminum mask tape.
The utility model is rational in infrastructure, manufactures easily, and cost is low.Whenever the rare single line core color that is centering to of four pairs of foaming video signal cables has nothing in common with each other, and is convenient to quick differentiation, and the every pair of wrapped plastic-aluminum of foaming video signal cable mask tape prevents to interfere with each other.Cable core is provided with comprehensive shielded layer outward, and shielding density strengthens its interference free performance greatly near 100%, ensures data.Can satisfy the transmission requirement of high-speed high capacity fully, and be applied to HDMI (High Definition Multimedia Interface) (HDMI).Wrapped polyester film between braid shielded net and oversheath, oversheath is easily peeled off during use.The oversheath of cable adopts the environmental protection polyvinyl chloride sheath, and the environmental-protecting performance of this type of material reaches European ROHS environmental protection command request.This cable outward appearance rounding, transmission performance are excellent, and shield effectiveness is good, and antijamming capability is strong, and environment-protecting clean uses through test, is subjected to client's high evaluation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 conductor, 2 foaming polyethylene insulation, 3 plastic-aluminum mask tape lapping layers, 4 conductors, 5 polyvinyl chloride insulations, 6 tin plated wire earth connections, 7 plastic-aluminum mask tapes, 8 tin plated wire mesh grids, 9 polyester film lapping layers, 10 oversheaths.
Embodiment
With four pairs of foaming video signal cable, two groups of twisted pair wires and three independent audio electronics line strandings, cable core is provided with comprehensive shielded layer and polyester film lapping layer 9 outward, and polyester film lapping layer 9 is wrapped at comprehensive shielded layer.The conductor 1 of foaming video signal cable is a tinned copper wire, and insulating barrier adopts polyethylene foamed insulation 2.Four pairs of foaming video signal cables carry out stranded with different pitches, have at least in every pair of foaming video signal cable on the eradication edge core color (color has nothing in common with each other) that is different from other insulated wire cores is set, be convenient to quick differentiation, respectively add the box-like tin plated wire earth connection 6 of multiply bundle in the time of the insulated wire cores pair twist, and wrapped plastic-aluminum mask tape 3, prevent to interfere with each other.The conductor 4 of audio electronics line also is a tinned copper wire, and insulating barrier adopts environmental protection polyvinyl chloride insulation 5, and two pairs of twisted pair wires wherein do not add lapping layer.The outside wrapped plastic-aluminum of cable core mask tape 7, braiding tin plated wire mesh grid 8 constitutes comprehensive shielded layer on the lapping layer of plastic-aluminum mask tape 7.Oversheath 10 adopts environmental protection polyvinyl chloride to be extruded on the polyester film lapping layer 9.
