Abstract
An audio connecting wire comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath from inside to outside, wherein the inner conductor, the insulating layer, the outer conductor and the outer sheath are of a coaxial structure. The audio connecting wire is characterized in that a plurality of hollow insulating pipes are arranged between the insulating layer and the outer conductor and concentrically stranded around the insulating layer. The hollow insulating pipes are made of combined insulating mediums comprising high molecular materials and air, which effectively reduces the capacitance between the inner conductor and the outer conductor, reduces the distortion of transmission signals, and realizes the small signal attenuation; when the connecting wire frequently moves in use, the high stability of the structure can be kept, audio signals are transmitted efficiently; and additionally, the audio connecting wire has the advantages of unique and novel structure and strong practicability, and can be used for connecting an electronic musical instrument, a microphone and single/double-channel sound equipment.
Description
Technical field
The utility model relates to electric wire or cable, especially a kind of audio frequency wire connecting or cable specialized in.
Background technology
Now be used to transmit the dedicated wires (cable) of electrophonic musical instrument audio signal both at home and abroad, general adopt an electric conductor and be close to this structure of insulating sleeve on the electric conductor, though such electric wire (cable) can transmitting audio signal, but in transmission course, all there are defectives such as distorted signals is big, strength retrogression's height, especially in requiring audiorange, carry out signal to occur and disturbing the state no interference signal transmission.At present, a lot of technological improvements also occurred, as the patent No. 01238501.8, it comprises coaxial inner wire, insulating barrier, outer conducting layer, outer jacket, between insulating barrier and outer conducting layer, outer semiconducting layer is arranged, have advantage simple in structure, convenient for production, that definition is high.But transmitting audio signal in high quality and anti-interference aspect also be not very desirable, cost is also higher, produces inconvenient.
The utility model content
The purpose of this utility model provides the audio connecting cord that a kind of distortion is low, the strength retrogression is little, simple and practical, makes connecting line also can keep highly stable in frequent moving.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: a kind of audio connecting cord, inner wire, insulating barrier, outer conductor, oversheath are arranged from inside to outside, and inner wire, insulating barrier, outer conductor, oversheath be coaxial configuration,
It is characterized in that many hollow insulated tubes are arranged between described insulating barrier and the outer conductor, be around insulating barrier that concentric type arranges.
Improve, described many hollow insulated tubes are to be concentric type around insulating barrier to twist together again.
As improvement, described hollow insulated tube be the pipe made of a kind of macromolecular material, in fill the comprehensive dielectric of air, the external diameter of described hollow insulated tube is 1.6～2.2mm, internal diameter is 0.8～1.2mm.
As improvement, the outer setting of described hollow insulated tube has the stranded twining package tape of the stranding of being close to, and hollow insulated tube is fixed on the insulating barrier outer rim.
As improvement, described outer conductor is that the braiding of many one metal wires conductor forms.
As improvement, described inner wire is that single core or multicore wire are stranded.
As improvement, the outside of described oversheath is provided with bright colored braid.
As improvement, be provided with the transparent sheath layer in the outside of the colored braid of described light.
The utility model can significantly reduce the capacitance between internal and external conductor,
Compared with prior art, advantage of the present utility model is: be provided with many hollow insulated tubes between insulating barrier and outer conductor, so just can increase insulation effect greatly, reduce the capacitance between internal and external conductor effectively, make transmission signals distortion reduction, signal attenuation little, in the frequent moving process in connecting line uses, also can keep the highly stable of its structure, transmitting audio signal in high quality, and structure is unique novel, practical, can be used for electronic musical instrument, microphone is connected with single, double road stereo set.

Fig. 2 is second kind of structural section figure of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment 1
As shown in Figure 1, a kind of audio frequency connects electric wire, comprises inner wire 1, insulating barrier 2, outer conductor 5, the oversheath 6 of coaxial configuration, and is followed successively by inner wire 1, insulating barrier 2, outer conductor 5, oversheath 6 from inside to outside.The hollow insulated tube 3 of the six roots of sensation is arranged between insulating barrier 2 and outer conductor 5, and to be concentric type stranded around insulating barrier 2, and six hollow insulated tubes 3 are along axially being that similar zigzag shape is twisted exactly.Hollow insulated tube 3 is the comprehensive dielectric that a kind of macromolecular material and air are formed, and the external diameter of hollow insulated tube is 2.0mm, internal diameter 1mm, in be air; There is the stranded twining package tape 4 of the stranding of being close to the outside of hollow insulated tube 3, and hollow insulated tube 3 is fixed on insulating barrier 2 outer rims.Inner wire 1 is a metal wire structure, and outer conductor 5 forms for the braiding of many one metal wires conductor.
The utility model is compared with now common connecting line, can significantly reduce the capacitance between internal and external conductor, and is as shown in the table:
Make transmission signals distortion reduction, signal attenuation little, in the frequent moving process in connecting line uses, also can keep the highly stable of its structure, transmitting audio signal in high quality,
As shown in Figure 2, difference from Example 1 is the oversheath 6 outer colored braids 7 of one deck light that also are surrounded by, and is surrounded by transparent sheath layer 8 outside the colored braid 7 of light, to increase the fastness and the aesthetic feeling of electric wire.
