Abstract
The utility model relates to a multimedia connecting wire, in particular to a high definition multimedia connecting wire. The multimedia connecting wire comprises four flat coils, a round coil and a jacket, wherein each flat coil is formed by two signal wires, a ground wire, and flat wing-spread aluminium foil wrapping the outside layer; the round coil is formed by seven PE core wires, a ground wire, and wing-spread aluminium foil wrapping the outside layer; and the jacket adopts a flat-shaped structure and wraps the four flat coils and the round coil. The high definition multimedia connectingwire has low cost and simple manufacturing process.
Description
Technical field
The utility model relates to a kind of multi-media connecting line.
Background technology
At present, the wire rod structure of HDMI (High Definition Multimedia Interface Cable, high-definition multi-media connecting line) is generally circle.Referring to Fig. 1, two holding wires 11 and a ground wire 12 are rolled into one circular coil 1 by the aluminium foil 13 of spreading the wings, high-definition multi-media connecting line comprises four strands of such circular coils 1, also comprise 7 PE lines 2 and a ground wire 3, the skin of 1,7 PE lines 2 of these four strands of circular coils and a ground wire 3 is made circle by litzendraht wire, form braid 4, the skin of braid is added sheath 5.The manufacturing process of above-mentioned high-definition multi-media connecting line is, at first, with heart yearn machine work copper wire, and adopts bag paper mechanism to make 4 strands of described circular coils 1, makes 7 PE heart yearns 2 and four pairs of holding wire 13 stranding twisted wires with the stranding stranding machine; Secondly, with braiding machine stranding twisted wire; At last, according to shielding requirements, make braid and add ground wire, adopt sheath machine to make sheath, high-definition multi-media connecting line completes.
The shortcoming of above-mentioned high-definition multi-media connecting line is that manufacture craft process complexity need be carried out the braiding process, the time-consuming material that takes.In addition, circular wire rod physical property in BENDING PROCESS repeatedly will be affected.
The utility model content
It is simple that the purpose of this utility model provides a kind of making, the high-definition multi-media connecting line of the material-saving that saves time.
For achieving the above object, the utility model provides following technical scheme:
High-definition multi-media connecting line,
Comprise
Four strands of flatwise coils, per share flatwise coil are by two holding wires, a ground wire and wrap in the outer field aluminium foil of spreading the wings and constitute;
One circular coil, it is by seven PE heart yearns, a ground wire and wrap in the outer field aluminium foil of spreading the wings and constitute;
Sheath, it is a flat, it wraps up described four strands of flat wires and one circular coil.
The manufacturing process of above-mentioned high-definition multi-media connecting line is, at first, with heart yearn machine work copper wire, and adopts bag paper mechanism to make 4 strands of described flatwise coils, with stranding stranding machine 7 PE heart yearns of making and add ground wire; At last, adopt sheath machine to add outer field flat sheath, high-definition multi-media connecting line completes.Compared to the manufacturing process of existing circular high-definition multi-media connecting line, reduced the process of stranding twisted wire and braiding, so both reduced waste of material, saved production time and production cost again.In addition, the cross section of lenticular wire is a square, and such moulding has guaranteed that wire rod does not influence the physical property of wire rod in repeatedly crooked process, make the life-span of wire rod elongated.Also have, the aluminium foil of spreading the wings of lenticular wire tighter the wire rod parcel, good airproof performance can reduce airborne oxygen like this and enter, and the inner wire of wire rod is not easy oxidized, has guaranteed the good transmission of signal in the holding wire.
Further technical scheme is,
There are a plurality of draw-in grooves the inboard of described sheath, and described four strands of flatwise coils and one circular coil snap into respectively in each draw-in groove.
Four strands of flatwise coils are embedded in respectively in each groove of sheath inboard, can guarantee every signal line in use like this, keep stable physical property.
Description of drawings
Fig. 1 is the structural representation of existing high-definition multi-media connecting line;
Fig. 2 is the structural representation of high-definition multi-media connecting line of the present invention.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 2, high-definition multi-media connecting line comprises,
Four strands of flatwise coils 101, per share flatwise coil 101 are by two holding wires 1011, a ground wire 1012 and wrap in the outer field flat aluminium foil 1013 of spreading the wings and constitute.
One circular coil 102, it is by seven PE heart yearns 1021, a ground wire 1022 and wrap in the outer field aluminium foil 1023 of spreading the wings and constitute.
Certainly, the utility model high-definition multi-media connecting line also can have other distortion.In a word, doing conspicuous change according to the prompting of the foregoing description, and other every changes that do not break away from the utility model essence, all should be included within the described scope of claim.
