Abstract
The utility model relates to a mobile terminal high-definition video-audio transmission line, which comprises 5 core wires and an outer sleeve coated outside the 5 core wires, wherein the outer sleeve comprises a sheath layer and a tinned copper braid from outside to inside; the five core wires include 2 transmission lines, 2 power lines and 1 control line, the 5 core wires are further coated by aluminum foil layers, conductors of the transmission lines are formed by twisting tinned copper filaments, insulating layers of the transmission lines adopt a foam-skin structure, inner layers are foaming polyethylene, outer layers are solid polyethylene, the two transmission lines are twisted into a wire pair, the wire pair is coated together with a ground wire in a single-sided aluminum foil, and a hot-melt polyester belt is coated outside the single-sided aluminum foil to form a shielding layer. The mobile terminal high-definition video-audio transmission line greatly reduces the physical size, solves the problem of automatic charging, improves the electromagnetic interference resistance performance of lines, and can ensure the low loss and stable synchronization performance of audio and video signal transmission of lines.
Description
Technical field
The utility model relates to a kind of transmission line, relates in particular to a kind of portable terminal high-definition audio and video transmission line.
Background technology
A kind of portable terminal high-definition audio and video transmission line that the utility model is related, the special type that mainly is based on the exploitation of MHL Application of Interface is transmitted wire rod.MHL(Mobile High-Definition connects Link) Chinese is portable terminal high-definition audio and video standard interface, to propagate exploitation for mobile phone or portable electric appts audio-video signal specially by mobile high definition interconnection technique alliance (MHL Consortium), and new novel connection and the transmission technology of releasing.MHL interface and USB interface can be installed in cable of the present utility model two ends, one end connection mobile phone, digital camera, Digital Video are connected mobile terminal device to connect with portable media player, the other end connects HDTV (High-Definition Television), high-clear display, high definition projecting apparatus etc. and plays display device, thereby realizes high definition, two-forty, the low-loss transmission of mobile terminal device audio-video signal.In addition, this wire rod also possesses the function for the charging of portable terminal electronic equipment.
Up to the present, the mobile terminal signal transmission field is most widely used to be HDMI or USB3.0 wire rod, the major defect that these two kinds of wire rods exist: the one, the wire rod physical size is large, and wherein the HDMI wire rod includes 19 heart yearns, and the USB3.0 wire rod includes 10 heart yearns, the finished product external diameter is more than 6.0mm, many heart yearns have improved the welding difficulty of miniature interface, are difficult to guarantee the quality of interface, and external diameter causes greatly high material consumption simultaneously, the corresponding increase of volume and weight is unfavorable for carrying; The 2nd, the transmission electric property is not ideal enough, these two kinds of wire rods all adopt video, audio signal by different lines to transmitting, cause easily the asynchronous or loss of video, audio signal, and at present the high-transmission frequency of technology is 5GHz, is difficult to satisfy the high-speed transfer demand of high-definition signal of new generation.
The utility model content
Specification requirement according to the MHL interface standard, defective for existing HDMI line and the existence of USB3.0 line, the utility model provides a kind of portable terminal high-definition audio and video transmission line, mainly solve reduce physical size, line to the synchronous transmission audio frequency and video, improve transmission frequency, carry the problem such as charging.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Portable terminal high-definition audio and video transmission line comprises 5 heart yearns and is coated on the outer overcoat of 5 heart yearns that described overcoat comprises restrictive coating and tinned copper braid from outside to inside; Described 5 heart yearns comprise 2 transmission lines, 2 power lines and 1 control line, described 5 heart yearns also coat aluminium foil layer outward, to be that the tin-coated copper monofilament is stranded form the conductor of described transmission line, the transmission line insulating barrier adopts the bubble skin structure, internal layer is polyethylene foamed, and skin is real core polyethylene, and 2 transmission lines are twisted into line to rear, in ground wire is wrapped in the single face aluminium foil, and melts polyester belt in single face aluminium foil outer cladding heat and form screen.
As preferably: the count of described tinned copper braid is more than or equal to 85%.
As preferably: described restrictive coating adopts the PVC plastic sheath.
The beneficial effects of the utility model are: because heart yearn of the present utility model only is 5, the wire rod external diameter is reduced to 4.2mm from 6.0mm, and it is about 50% that volume reduces, and greatly reduced physical size; Owing to be provided with power line, solved the problem of automatic charging; Because cored wire conductor all adopts the strands structure, both satisfied the transmission requirement of conductor, solved again the physical property requirement such as flexibility, mechanical strength of conductor, conductor designs three layers of shielding from inside to outside simultaneously, improve the anti-electromagnetic interference performance of wire rod, can guarantee low-loss and the stable net synchronization capability of wire rod transmission tone vision signal.Transmission frequency of the present utility model improves 20%, brings up to 6GHz from 5GHz, realizes the lifting of signal transmission rate.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, a kind of portable terminal high-definition audio and video of the utility model transmission line preferred implementation is made detailed description:
A kind of portable terminal high-definition audio and video transmission line as shown in Figure 1 comprises 5 heart yearns and is coated on the outer overcoat of 5 heart yearns that described overcoat comprises restrictive coating 1 and tinned copper braid 2 from outside to inside; Described 5 heart yearns comprise 2 transmission lines 3,2 power lines 6 and 1 control line 9, described 5 heart yearns also coat aluminium foil layer outward, two transmission lines 3 are realized the set synchronous transmission of video and audio signal, the conductor of described transmission line 3 is 19 bursts of stranded forming of the zinc-plated monofilament of 0.064mm, transmission line 3 insulating barriers adopt the bubble skin structure, internal layer is polyethylene foamed (PE), skin is real core polyethylene, 2 transmission lines 3 are twisted into line to rear, in ground wire 7 is wrapped in single face aluminium foil 5, and melts polyester belt 4 in single face aluminium foil 5 outer cladding heat and form screens.
The count of described tinned copper braid 2 is more than or equal to 85%.Described restrictive coating 1 adopts the PVC plastic sheath.
