Embodiment

It refer to shown in Fig. 1 to Fig. 3, be a kind of that show the concrete structure of the preferred embodiment of the utility model Scalable Anti-tangling earphone line, automatic signal generator is carried out for transmitting（For example, it may be mobile phone, MP3, MP4, tablet personal computer, electricity The equipment such as brain）Electric signal.

As shown in figure 1, the structure of the earphone cord includes one first plug 10, two-loudspeaker 20, is electrically connected at this and two raises Headset cord 30 between sound device and the first plug.An extension cable 40 is still further comprised, the middle part of the extension cable 40 is twined Steering knuckle 50, the other end are provided with around one end for flexible stretchable helical coil structure 41, the extension cable 40 Provided with the second plug 60.Cable 40 is detachable is connected with extension for the headset cord 30, when headset cord 30 is with extending cable During 40 engagement, first plug 10 is connected with steering knuckle 50.So, earphone cord is divided into two parts, and user can be according to need It is stitched together or is used alone, it is not necessary to worries that earphone cord is long or too short, psychological burden is discharged, meet man-machine work Cheng Xue and psychology.In addition, making earphone cord be provided with flexible work(due to being provided with helical coil structure 41 on extension cable 40 Can, it is simple in construction, easy to use, manufacturing cost is low.Further, due to the first plug 10 with it is rotatable after the grafting of steering knuckle 50, Play antiwind purpose.

Wherein, as shown in Figures 2 and 3, the inside of the headset cord 30 is conductor wire 31, and outside is coated with insulator 32, the insulator 32 is in triangular prism shape, and the side of the insulator 32 has multiple label layers 33 with different colours.This In embodiment, the quantity of the label layer 33 is three, and three label layers 33 are bonded in the adjacent of the insulator 32 of triangular prism shape On side, it is in channel form 34 to constitute the stitching section between sign body, each label layer 33.It is arranged to triangular prism by by insulator 32 Shape, the structural stability provided using triangular prism reduces the torsion degree of earphone cord, is passed with the signal for ensuring earphone wire Transmission function and service life.Use simultaneously and be distributed in the sign body that multiple marking layers of triangular prism side are spliced, Duo Gebiao Show the connecting portion formation different colours between layer, highlight the stereoscopic vision of triangular prism shape, lift the vision novelty and valency of product Value sense.

The insulator 32 is thermoplastic polyester elastomer, ensure that the good insulating properties of call wire.In addition, insulation Some cotton threads 35 are embedded with inside body 32, because cotton thread 35 has toughness, the tensile capacity of headset cord 30 can be improved, outside Boundary's pulling force is born by cotton thread 35, without putting on conductor wire 31, conductor wire 31 is protected, it is ensured that data message Normal transmission, effectively extend the service life of earphone cord, enhance the mechanical strength of earphone cord.

The conductor wire 31 includes an electrode line 311, a buffer insulation layer 312, a negative line 313.The electrode line 311 is By being constituted positioned at least one carbon nano tube line 3111 at center and many superconduction ribbon lines 3112, each superconduction ribbon line 3112 is twined It is around in the periphery of carbon nano tube line 3111.The buffer insulation layer 312 is by being helically wrapped in electrode line by semi-synthetic insulating paper 311 peripheries are formed.The negative line 313 is to be wound in the periphery of buffer insulation layer 312 by many superconduction ribbon lines 3112 to be formed.

So, electrode line 311 and negative line 313 are arranged on same conductor wire 31 simultaneously, respectively as same conductor wire Positive pole, negative pole on 31 positive pole and cathode conductor, with the first plug 10 are electrically connected with.Also, the electrode line 311 and negative line By the mutually insulated of buffer insulation layer 312 between 313, so, two polar curves formation current loop on same wire, relatively Need to be separated into positive wire, cathode conductor into the setting of two lines cable in tradition, this product reduces the diameter of a cable.

Further, since electrode line 311 and negative line 313 are made of superconductor, positive electrode current and cathodal current are usual With almost identical size and cancel out each other, be nearly free from voltage drop, so as to reduce voltage loss, earphone can be improved Tonequality.

Further, because in the centrally disposed carbon nano tube line 3111 of electrode line 311, the carbon nano tube line 3111 is in the earphone As a kind of bearer element in line, for bearing pulling force caused by external tensile force or deadweight, or the earphone cord is being reversed, turned round It is produced around folding power when bent.It is understood, however, that because carbon nano tube line 3111 also has good electric conductivity, when just Polar curve 311 is fractureed in use, and carbon nano tube line 3111 can also be used as wire, so as to further extension earphone Life-span.

In the present embodiment, the carbon nano tube line for the non-twisted that the carbon nano tube line 3111 can constitute for many CNTs Or the carbon nano tube line reversed.The diameter of the carbon nano tube line can be 4.5 nanometers~100 microns.The carbon nanometer of the non-twisted CNT membrane can be handled and obtained by pipeline by organic solvent.The CNT line length of the torsion is not limited, a diameter of 0.5 nanometer~100 microns.Further, the carbon nano tube line of above-mentioned torsion can be handled using a volatile organic solvent.Waving In the presence of the surface tension produced during the organic solvent volatilization of hair property, adjacent carbon is received in the carbon nano tube line of the torsion after processing Mitron is combined closely by Van der Waals force, the diameter and specific surface area of the carbon nano tube line of torsion is further reduced, so that Its density and intensity further increase.It is appreciated that the CNT in carbon nano tube line 3111 can be single-walled carbon nanotube, Double-walled carbon nano-tube or multi-walled carbon nanotube, or its combination.When the carbon nano tube line 3111 is single-walled carbon nanotube, The diameter of the single-walled carbon nanotube can be 0.5 nanometer~50 nanometers.When the carbon nano tube line 3111 is double-walled carbon nano-tube When, the diameter of the double-walled carbon nano-tube can be 1 nanometer~50 nanometers.When the carbon nano tube line 3111 is multi-walled carbon nanotube When, the diameter of the multi-walled carbon nanotube can be 1.5 nanometers~50 nanometers.

It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made Any limitation, therefore every any trickle amendment made according to technical spirit of the present utility model to above example, equivalent change Change with modification, in the range of still falling within technical solutions of the utility model.
