The peripheral ground wire is buried between the aluminum foil and the braid layer. An outer layer of the braid layer is provided with the sheath. Each coil comprises a pair of signal lines, an internal ground wire, aluminum foil and a heat sealing film. The pair of signal lines and the internal ground wire are wrapped by the aluminum foil which is wrapped by the heat sealing film. According to the HDMI line, a ground line of each pair of signal lines is changed to an enamel covered wire from a bare copper wire, the aluminum foil is coated by a layer of heat sealing film, the heat sealing film has certain stickiness after being heated, in this way, the signal lines and the ground wire are tightly wrapped by spreading aluminum foil, and an aluminum foil loosening or ground wire breaking phenomenon is prevented in a follow-up process or product use.
Description
Technical field
The present invention relates to a kind of multi-media connecting line.
Background technology
High-definition multi-media connecting line (being called for short the HDMI line) mainly is used in transmission high-definition digital signal between DVD, PS3, digital TV in high resolution base top box and digital TV in high resolution or the display device.The HDMI line is transmission of audio and vision signal simultaneously.HDMI line delivery flow rate is large, and all information all are that the form of digital signal is transmitted.So just so that signal can distortion in transmission course.Because the HDMI line can integrate audio frequency, video signal transmission, and little lightweight, the good looking appearance of volume, so it will progressively replace existing audio-video signal and VGA line and will be widely used.
The structure of existing HDMI line is referring to Fig. 1, and it mainly comprises four strand circles 1, seven PE lines 2 and a peripheral hardware ground wire 3.Four strand circles 1 and seven PE lines 2 are wrapped up by aluminium foil 4, the aluminium foil 4 outer braids 5 that arrange, and ground wire 3 is embedded between aluminium foil 4 and the braid 5, and braid 5 skins are provided with sheath 6.Wherein, per share coil 1 comprises again a pair of holding wire 11, built-in ground wire 12 and the aluminium foil 13 of spreading the wings, and the aluminium foil 13 of spreading the wings is rolled into one coil 1 with holding wire 11 and ground wire 12.Wherein, coil 1 is used for the carry high frequency digital signal, and seven PE lines 2 are electric wire, are used for conduction.
In the prior art, ground wire 12 is bare copper wire, by the coating of the aluminium foil of spreading the wings, to reach not the ground wire short circuit with other coils.But, in some Special use occasions, for example when the HDMI line bends than wide-angle, ground wire 12 may be broken through the aluminium foil of spreading the wings that is wrapped in its periphery, ground wire between a plurality of like this coils just is easy to touch each other, so bare copper wire is not safe enough as ground wire.In addition, aluminium foil has been realized the function of electromagnetic shielding and insulation parcel simultaneously although spread the wings, but as from the foregoing, the tightness of its insulation parcel also is still waiting to promote, and the production technology of the aluminium foil of spreading the wings is complicated, cost compare high (aluminium foil of spreading the wings is take soft rolling aluminum foil and polyester film as former material, and it is compound that the aluminium foil semi-finished product after cutting and wider film are made secondary, and polyester film extends out respectively at two sides of aluminium foil).
The utility model content
The objective of the invention is the essential structure of HDMI line is changed, a kind of novel HDMI connecting line is provided; This purpose is realized by following technical scheme:
A kind of HDMI line comprises: some strand circles, some PE lines, peripheral hardware ground wire, aluminium foil, braid and a sheath; Some strand circles and some PE lines are wrapped up by aluminium foil, and aluminium foil arranges braid outward, and the peripheral hardware ground wire is embedded between aluminium foil and the braid, and the braid skin is provided with sheath; It is characterized in that: per share coil comprises in a pair of holding wire, one establishes ground wire, aluminium foil and heat-sealing film, establishes ground wire in a pair of holding wire and one and is wrapped up by aluminium foil, and aluminium foil is outer and then coat described heat-sealing film.
In the above-mentioned HDMI line, establishing ground wire in described is enamelled wire.
In the above-mentioned HDMI line, concrete four or the five strand circles of described some strand circles, described some PE lines are specially seven PE lines.
In the above-mentioned HDMI line, described some strand circles are specially five strand circles, and described some PE lines are specially four PE lines.
In the above-mentioned HDMI line, two in the described PE line twist together.
Another object of the present invention provides a kind of manufacture method of above-mentioned HDMI line, realizes that the technical scheme of this purpose is as follows:
The outside of the aluminium foil of the present invention outside every pair of holding wire coats the last layer heat-sealing film, heat-sealing film has certain viscosity after heating, so just can be with aluminium foil being coated on holding wire and the ground wire tightly of spreading the wings, in using, follow-up operation or finished product just can not occur again that aluminium foil does not get loose or the ground wire breaking phenomena.In addition, in establish ground wire and adopted enamelled wire, even aluminium foil and heat-sealing film have got loose, also can be safer than traditional bare copper wire.

Fig. 1 is the structural representation of existing high-definition multi-media connecting line.
Fig. 2 is the structural representation of the high-definition multi-media connecting line that provides of the embodiment of the invention one.
Fig. 3 is the structural representation of the high-definition multi-media connecting line that provides of the embodiment of the invention two.
The invention will be further described below in conjunction with drawings and Examples.
Embodiment
Embodiment one
As shown in Figure 2, the HDMI line that provides of present embodiment comprises: four strand circles 1, seven PE lines 2, peripheral hardware ground wire 3, aluminium foil 4, braid 5 and a sheath 6.Four strand circles 1 and seven PE lines 2 are wrapped up by aluminium foil 4, the aluminium foil 4 outer braids 5 that arrange, and ground wire 3 is embedded between aluminium foil 4 and the braid 5, and braid 5 skins are provided with sheath 6.Wherein, per share coil 1 comprises again a pair of holding wire 11, built-in ground wire 12, aluminium foil 13 and a heat-sealing film 14, and aluminium foil 13 is rolled into one coil 1 with holding wire 11 and ground wire 12 (enamelled wire), heat-sealing film 14 and then be wrapped in aluminium foil 13 peripheries.Wherein, coil 1 is used for the carry high frequency digital signal, and seven PE lines 2 be electric wire, is used for conducting electricity, and two in seven PE heart yearns can twist together.The skin of four strands of circular coils 1, seven PE lines 2 and a ground wire 3 coats first one deck PET film, then coats aluminium foil 4, the aluminium foil 4 outer braids 5 that arrange, and peripheral hardware ground wire 3 is embedded between aluminium foil 4 and the braid 5, and braid 5 skins arrange sheath 6.
