Because the defective that above-mentioned existing HDMI cable installation exists, the design people is based on being engaged in this type of product design manufacturing for many years, amassing has abundant practical experience and professional knowledge, positive research and innovation in addition, to founding a kind of HDMI cable installation, can improve the general molding structure of existing HDMI cable installation on the market, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improvement, finally create the utility model that has practical value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the defective that existing HDMI cable installation exists, and provide a kind of cable installation of high-definition multimedia digital data transmission, overcome the defective that existing HDMI cable installation exists, improve the tightness degree of HDMI cable installation, and then improved the high-definition data transmission effect of HDMI cable installation.
The utility model solves its technical problem underlying and realizes by the following technical solutions.cable installation according to the high-definition multimedia digital data transmission that the utility model proposes, by outer jacket, the tin-coated copper braid over braid, aluminium foil, the PET band, twisted component wires, single-core line and interstitial wire form, PET band parcel is one twisted component wires at least, at least one single-core line and one interstitial wire at least, the coated outside aluminium foil of PET band, the coated outside tin-coated copper braid over braid of aluminium foil, the coated outside outer jacket of tin-coated copper braid over braid, twisted component wires is by two heart yearns, article two, anti-electromagnetic interference ground wire, insulating barrier and aluminium foil wheat are drawn composition, the aluminium foil wheat is drawn with two heart yearns of the wrapped parcel of helical form, insulating barrier parcel aluminium foil draws and two anti-electromagnetic interference ground wires by wheat, twisted component wires surrounds square shape on cross section, have one single-core line at least and at least one interstitial wire be positioned at the centre of square shape, there is one single-core line at least to be positioned at four angles of square shape, anti-electromagnetic interference ground wire is the naked metal wire that multiply metal fine strand system forms, the cross section of interstitial wire is ellipticity.
Better, described two anti-electromagnetic interference ground wires lay respectively at the both sides of two heart yearns.
Better, described heart yearn is comprised of heart yearn metal wire and core insulation layer, and the core insulation layer wraps up the heart yearn metal wire equably.
Better, described single-core line is comprised of single-core line metal wire and single-core line insulating barrier, and the single-core line insulating barrier is parcel form heart yearn metal wire equably.
The cable installation of high-definition multimedia digital data transmission described in the utility model, the beneficial effect of its generation is: split conductor surrounds square shape on cross section, add the filling effect of interstitial wire, make the structure of cable installation tightr, withstand voltage properties improves, and then has promoted the reliability of cable installation; Anti-electromagnetic interference ground wire is the naked metal wire that multiply metal fine strand system forms, the contact area of comparing single metal wire in the contact area of welding position metal fine bundle and pad like this wants large, increase the fastness of pad, and then improved the reliability of the cable installation of high-definition multimedia digital data transmission; No matter wire rod is crooked to any direction, there is an anti-electromagnetic interference ground wire to be in compressive state, this has just guaranteed the pulling force that the shell pad of anti-electromagnetic interference ground wire and HDMI terminal can not be continued, and guarantees the stability of pad.
