Abstract
A kind of high shielding practicality earphone cord, for audio signal transmission, it is characterised in that：Including multigroup audio signal transmission unit, every group of audio signal unit is made up of successively stranded wire, screen layer, middle tegillum, the screen layer is made up of internal layer and outer layer, internal layer be aluminium foil, copper foil, tinfoil it is any, outer layer is braiding or the wire being wrapped on the outside of the internal layer, the middle tegillum being made up of polyether-ketone is enclosed with the outside of the screen layer, multigroup audio signal transmission unit is wrapped up by serving.Screen layer is added, screen layer is conducting metal material, can not only ensure that wire rod produces stable linear impedance, it is ensured that the stability of signal transmission, the pull resistance of wire rod can also be improved, used while being also used as drain wire.Middle tegillum is made up of polyether-ketone so that cable has good resistance to elevated temperatures, and tensile property adds the life-span of cable.
Description
Technical field
The utility model is related to a kind of high shielding practicality earphone cord.
Background technology
Signal is during transmission, if the characteristic impedance in transmission path changes, and signal will be in impedance not
Continuous node produces reflection, causes distorted signals.Because original technology uses electric signal, existing technology is more and more used
Analog signal, the audio cable of prior art is typically using the common cable for not possessing screen layer, in high voltage or high magnetic
When place uses ordinary audio cable, it may appear that noise so that voice call can seriously be interfered.
Furthermore, carry use for convenience, audio cable needs frequently to be stored and deployed, due to drawing constantly repeatedly
Stretch, audio cable of the prior art is very easy to damage, and service life is low.
Utility model content
In order to solve the problems, such as techniques discussed above, the utility model provides following technical scheme：
A kind of high shielding practicality earphone cord, for audio signal transmission, including multigroup audio signal transmission unit, every group
Audio signal unit is by stranded wire（1）, screen layer, middle tegillum（4）Constitute successively, the stranded wire is coaxial knot
Structure, the screen layer is by internal layer（2）And outer layer（3）Constitute, internal layer be aluminium foil, copper foil, tinfoil it is any, outer layer for braiding
Or the middle tegillum for being enclosed with and being made up of polyether-ketone on the outside of the wire on the outside of the internal layer, the screen layer is wrapped in, it is multigroup
The audio signal transmission unit is by serving（5）Parcel.The structure of coaxial line, can effective transmission of analogue signal, cause signal
The complete distortion of signal will not be caused in this structure.
Further, the serving is thermoplastic elastomer (TPE) material so that earphone cord has good elastic force, so as to protect
Life of product is longer than the life-span of general PVC products.
Further, the audio signal transmission unit is four groups, and the sections of four groups of audio signal transmission units is into square
Arrangement.
Further, it is provided with anti-elater in the center of four groups of audio signal transmission units（6）, the anti-elater is aramid fiber yarn.
Compared to prior art, the beneficial effects of the utility model are：
1st, screen layer is added, screen layer is conducting metal material, can not only ensures that wire rod produces stable characteristic resistance
It is anti-, it is ensured that the stability of signal transmission, the pull resistance of wire rod can also be improved, is used while being also used as drain wire；Together
The structure of axis, can effective transmission of analogue signal, cause signal not cause the complete distortion of signal in this structure；
2nd, middle tegillum is made up of polyether-ketone so that cable has good resistance to elevated temperatures, and tensile property adds cable
Life-span；
3rd, the setting of anti-elater so that earphone cord possesses antiballistic characteristics；
4th, the application of new structure so that earphone cord data not only can also transmit simulation letter with transmitting telecommunication number
Number.
Brief description of the drawings
It is described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter more of the present utility model specific real
Apply example.Identical reference denotes same or similar part or part in accompanying drawing.It should be appreciated by those skilled in the art that
What these accompanying drawings were not necessarily drawn to scale.In accompanying drawing：
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
As shown in figure 1, a kind of high shielding practicality earphone cord, is passed for audio signal transmission, including multigroup audio signal
Defeated unit, every group of audio signal unit is made up of successively stranded wire, screen layer, middle tegillum, and the screen layer is located at described
The outside of stranded wire, the screen layer is made up of internal layer 2 and outer layer 3, internal layer be aluminium foil, copper foil, tinfoil it is any,
Outer layer is braiding or the wire being wrapped on the outside of the internal layer, adds screen layer, and screen layer is conducting metal material, not only
It can ensure that wire rod produces stable linear impedance, it is ensured that the stability of signal transmission, the pull resistance of wire rod can also be improved,
Simultaneously drain wire is also used as to use.The middle tegillum being made up of polyether-ketone is enclosed with the outside of the screen layer, it is multigroup described
Audio signal transmission unit is wrapped up by serving 5.The serving is thermoplastic elastomer (TPE) material.The stranded wire is same
Axis structure.The structure of coaxial line, can effective transmission of analogue signal, cause signal signal will not be caused to lose completely in this structure
Very.
The audio signal transmission unit is four groups, and the sections of four groups of audio signal transmission units is into square arrangement.In
Tegillum is made up of polyether-ketone so that cable has good resistance to elevated temperatures, and tensile property adds the life-span of cable.
Anti- elater 6 is provided with the center of four groups of audio signal transmission units, the anti-elater is aramid fiber yarn.Anti- elater is set
Put so that earphone cord possesses antiballistic characteristics.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope
The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The scope of type is understood that and regarded as to cover other all these variations or modifications.
