Detailed description of the invention

Please refer to shown in Fig. 1 to Fig. 9, that show the concrete structure of the embodiment of the utility model.

This flat earphone cord includes headset plug 10, headset cord 20, microphone module 30, left earplug 41 and right earplug 42; Wherein, this headset cord 20 includes main line 21, parts line 22 on the left side and part line 23 on the right side, this headset plug 10 is connected to main line 21 one end, main line 21 other end is then divided into and aforementionedly parts line 22 on the left side and part line 23 on the right side, and this left earplug 41 and right earplug 42 are connected respectively in parting line 22 on the left side, parting the extending end of line 23 on the right side.

In the utility model, this main line 21, to part line 22 on the left side and part line 23 on the right side be all rectangular flat structure in cross section, its all have two wider to side; Flat structure design, makes the flexibility of earphone cord better and resistance to bending performance is good, improves the service life of earphone cord.

As shown in Figure 3, this main line 21 includes outside and is rectangle the opaque cladding layer 51 of structure, the L channel wire 52 being coated on this opaque cladding layer 51 inside, R channel wire 53, earth lead 54 and microphone conductor 55, and this L channel wire 52, R channel wire 53, earth lead 54 and the microphone conductor 55 long side direction spacing along rectangular cross-sectional in opaque cladding layer 51 is arranged side by side; This four wire includes the electrical guide pillar 501 of inner abnormity, is coated on the internal insulating layer 502 of special-shaped guide pillar 501 periphery, is wound in the shielding sandwich layer 503 of internal insulating layer 502 periphery and is coated on the nontransparent of shielding sandwich layer 503 periphery and colored external insulation 504; Wherein, all side surfaces of the electrical guide pillar 501 of this abnormity are arranged with some grooves 5011 extended in the same way with the electrical guide pillar 501 of abnormity, increase the surface area of electrical guide pillar 501, improve laser propagation effect.

As shown in Figure 4, shown in its primary structure with Fig. 3, structure is identical, difference is, two of opaque cladding layer 51 shown in Fig. 4 wider to the rectangular recess 511 side being all arranged with some cross sections and being square, this rectangular recess 511 is extended in the same way with headset cord 20, and each rectangular recess 511 is arranged side by side along the long side direction spacing of the rectangular cross-sectional of opaque cladding layer 51; Its rectangular recess 511 can be that groove depth is consistent, also can change or the design of random groove depth varying type for gradual change or depth alternative expression; Had the setting of rectangular recess 511, the section thickness of opaque cladding layer 51 is differed, the display of its color to each wire in inside can be different, make exterior color show certain stereovision, add the change of headset cord 20 exterior color, more attractive in appearance.

As shown in Figure 5 and Figure 6, label layer 56 is also provided with in opaque cladding layer 51 shown in it, this label layer 56 is positioned at the wherein wider to side of opaque cladding layer 51, like this, be convenient to show required character pattern etc., and this label layer is exposed to earphone cord surface unlike in conventional art, it has the feature such as waterproof, abrasionproof, can not occur the problems such as wearing and tearing, fuzzy, disappearance in routine use process; Meanwhile, the headset cord 20 of flat structure is more suitable for the layout of this label layer 56, and enough wide plane is used for display, and display effect is also better.

As shown in 7 to Fig. 9, which show and part line 22 on the left side, part the cross section structure of line 23 on the right side, from above-mentioned introducing main line 21, just be divided into from main line 21 and part line 22 on the left side, part line 23 on the right side, part on the left side line 22 include opaque cladding layer 51 and and trestle column is arranged at the L channel wire 52 in opaque cladding layer 51, earth lead 54, part on the right side line 23 include opaque cladding layer 51 and and trestle column is arranged at the R channel wire 53 in opaque cladding layer 51, earth lead 54, groove 511 structural design of aforementioned main line 21 and label layer 56 design, also line 22 can parted on the left side, part on the right side on line 23 and embody according to actual needs, generally speaking, part line 22 on the left side, part wider that wider of line 23 slightly can be narrower than main line 21 on the right side, but this is not also for fear of the embodiment that aforementioned grooves 511 structural design and label layer 56 design.

Design focal point of the present utility model is, its each conductor structure be mainly wrapped by by opaque cladding layer and inside thereof is designed, make good, the resistance to bending performance of earphone cord internal structure compact and reasonable, flexibility good, improve the functional reliability of earphone, extend the service life of earphone; And by the design of opaque cladding layer, its external effects can meet the consumer demand pursuing individual character aesthetic feeling more; The traverse design of its space type side by side, can not connect each wire in wire as existing circle and bear against together, avoids connecting wire overall overheated and damage and connect wire, it connects wire good heat dissipation, and between each wire, reasonable distance is arranged, and improves noise phenomenon, be conducive to improving earphone audio;

And the setting of label layer, is convenient to show required character pattern etc., and this label layer is exposed to earphone cord surface unlike in conventional art, and it has the feature such as waterproof, abrasionproof, the problems such as wearing and tearing, fuzzy, disappearance can not be there is in routine use process; Meanwhile, the earphone cord of flat structure is more suitable for the layout of this label layer, and display effect is also better.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
