Description
Technical field
A kind of earphone cord technical field is the utility model is related to, referring in particular to a kind of stable signal transmission, efficiently three cores are same
Axle twisting type earphone cord.
Background technology
Existing earphone cord is usually that structure is single, and single material as single conductive material using common copper material
The signal transmission quality of matter is poor, and shielding anti-jamming effectiveness is poor, influences the acoustical quality of earphone, is enjoyed so as to influence the sense of hearing of people
By；Further, existing earphone cord structural strength is low, and pull resistance is weaker.
Therefore, it is necessary to work out a kind of new technical scheme to solve the above problems.
Utility model content
The utility model deficiency, main purpose present in above-mentioned prior art are to provide a kind of stable signal transmission
The efficiently coaxial twisting type earphone cord of three cores, it has good anti-interference, and signal transmission quality stablizes quick, raising music
Details sense and stereovision, meanwhile, improve wire rod structure intensity and pull resistance, also take into account the decorative effect of earphone wire.
To realize above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of stable signal transmission efficiently coaxial twisting type earphone cord of three cores, includes three singles, three lists
Core concentric stranding curl integrative-structure, there are transparent TPE jacket layers in the peripheral extrusion molding of integrative-structure；The single bag
Include aramid fiber packing, the twisted some tin for being compassingly set at aramid fiber packing periphery that from-inner-to-outer is set gradually
Copper alloy conductor and the TPEE insulating barriers for being coated on gun-metal conductor periphery.
As a kind of preferred scheme, the gun-metal conductor is evenly arranged in aramid fiber packing periphery.
As a kind of preferred scheme, also include ornamental tensile cord, the ornamental tensile cord and foregoing three singles
Concentric stranding curl integrative-structure together.
The utility model has clear advantage and beneficial effect compared with prior art, specifically：By using tin
Copper alloy conductor, has a good anti-interference, and signal transmission quality is stablized quick, improves details sense and the stereovision of music,
Tone color is become apparent from, increases the hearing enjoying of people, meanwhile, the earphone cord smart structural design is reasonable, improves wire rod
Structural strength and pull resistance, also take into account the decorative effect of earphone wire.
Brief description of the drawings
Fig. 1 is the end structure illustration of the embodiment of the utility model；
Fig. 2 is the dimensional structure diagram of the embodiment of the utility model（It is local）.
Drawing reference numeral explanation：
10th, single 11, aramid fiber packing
12nd, gun-metal conductor 13, TPEE insulating barriers
20th, transparent TPE jacket layers.
Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of stable signal transmission efficiently coaxial twisting type earphone cord of three cores, includes three
Single 10, the concentric stranding curl integrative-structure of three singles 10, has transparent in the peripheral extrusion molding of integrative-structure
TPE jacket layers 20；The single 10 includes the aramid fiber packing 11 that from-inner-to-outer sets gradually, twisted is compassingly set at
Some gun-metal conductors 12 of the periphery of aramid fiber packing 11 and the TPEE insulation for being coated on the periphery of gun-metal conductor 12
Layer 13, generally, TPEE insulating barriers 13 will not be designed to transparent configuration, can be designed as the TPEE insulating barriers 13 of three singles not
Same color, in order to be distinguished in processing procedure, it can also increase and decorative effect is presented outside earphone wire；Preferably, the gun-metal
Conductor is evenly arranged in the periphery of aramid fiber packing 11, and the gun-metal conductor 12 can be enamel-covered wire, i.e., is closed in tin copper
The outer surface of golden inner core is covered with insulating lacquer layer, and insulating lacquer layer can select self-adhering type insulating lacquer layer, so, is molding TPEE
During insulating barrier 13, some gun-metal conductors 12 can mutually bond formation one；The aramid fiber packing 11 is preferably triumphant
Fu La（English original name KEVLAR, also translations Ke Weila or Kevlar, material original name is " PPTA "）Virtue
Synthetic fibre fibrous material.
When actual design makes, generally, also include ornamental tensile cord, the ornamental tensile cord with foregoing three
The concentric stranding curl integrative-structure together of single 10, so, further increases the pull resistance of earphone wire, ornamental
Tensile cord is the concentric stranding curl together with three singles 10, and through aforementioned transparent TPE jacket layers, 20,360 degree are in completely
Reveal the profile of helicoidal structure so that earphone wire has preferably dicoration, can more meet the aesthetic need of different users
Ask, certainly, aforementioned decorative tensile cord can set one or more than two, and can arrange in pairs or groups different colours and different cross section shape
Ornamental tensile cord, stable connection degree and outer is combined to obtain ornamental tensile cord after the difference of three singles 10 is twisted
Shape aesthetic feeling.
The utility model designing points are that it mainly by using gun-metal conductor, has well anti-interference
Property, signal transmission quality are stablized quick, improve details sense and the stereovision of music, become apparent from tone color, increase listening for people
Feel and enjoy, meanwhile, the earphone cord smart structural design is reasonable, improves wire rod structure intensity and pull resistance, also takes into account ear
The decorative effect of machine wire rod.
It is described above, only it is the utility model preferred embodiment, not technical scope of the present utility model is appointed
What is limited, therefore every any trickle amendment, equivalent variations made according to the technical essence of the utility model to above example
With modification, in the range of still falling within technical solutions of the utility model.
