This shows, still there is defective in above-mentioned existing HDMI cable installation, and demands urgently being improved.
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, reduce the HDMI cable installation in the protruding amplitude that the carpet upper surface produces, reduced the infringement that is subject to when the HDMI cable installation is trampled.
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, twisted component wires and single-core line form, outer jacket wraps up one twisted component wires and one single-core line at least at least, the cross section of the cable installation of high-definition multimedia digital data transmission is flat, there is the space of 1 millimeter to 2 millimeters between adjacent twisted component wires, this space is filled by outer sheath material, described twisted component wires is by two heart yearns, article two, anti-electromagnetic interference ground wire, aluminium foil layer, PET band and tin-coated copper braid over braid form, aluminium foil layer is with two heart yearns of the wrapped parcel of helical form and two anti-electromagnetic interference ground wires, PET band parcel aluminium foil layer, tin-coated copper braid over braid parcel PET band, a branch of electric wire of described single-core line and an anti-electromagnetic interference ground wire composition is drawn with the wrapped parcel of helical form by the aluminium foil wheat, described anti-electromagnetic interference ground wire is the naked metal wire that multiply metal fine strand system forms, described two anti-electromagnetic interference ground wires lay respectively at the both sides of two heart yearns, described single-core line is comprised of single-core line metal wire and single-core line insulating barrier, the single-core line insulating barrier is parcel form heart yearn metal wire equably, described heart yearn is comprised of heart yearn metal wire and core insulation layer, the core insulation layer wraps up the 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: 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; The HDMI cable installation of flat can pass under carpet easily, and reduces in the protruding amplitude that the carpet upper surface produces, and has reduced the infringement that is subject to when the HDMI cable installation is subject to trampling; In addition, have the space of 1 millimeter to 2 millimeters between adjacent twisted component wires, this space is filled by outer sheath material, and outer sheath material can be shared the dynamics that part is trampled like this, has reduced the infringement that is subject to when the HDMI cable installation is subject to trampling; 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.
