This L channel wire, R channel wire and earth lead have included central hair, copper conductor, separator, insulating barrier and screen, this copper conductor is wound in outside central hair, this separator is wrapped in outside copper conductor, and this insulating barrier is wrapped in outside separator, and this screen is wrapped in outside insulating barrier.
As a kind of preferred version, the cross section of described protective layer is circular or triangle.
As a kind of preferred version, described protective layer is TPE material.
As a kind of preferred version, described sleeve pipe is transparent material.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution,
By being provided with a Y type separator in protective layer; the first cavity volume that the inside of protective layer is divided into three to be isolated from each other by this Y type separator, the second cavity volume and the 3rd cavity volume; and coordinate L channel wire, R channel wire and earth lead to be arranged in the first cavity volume, the second cavity volume and the 3rd cavity volume respectively; L channel wire, R channel wire and earth lead is so made to be isolated from each other separately; thus avoid the mutual interference between L channel wire, R channel wire and earth lead; reach the effect reducing noise, effectively improve sound quality.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

Embodiment
Please refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model, include plug 10, left earplug 20, right earplug 30 and wire rod 40.
Wherein, this wire rod 40 includes main line 41, left by-pass 42 and right by-pass 43, one end of this main line 41 is connected with plug 10, the other end of this main line 41 is connected with left by-pass 42 and right by-pass 43 by a connection piece 50, and the end of this left by-pass 42 and right by-pass 43 is connected with left earplug 20 and right earplug 30 respectively.
Specifically, as shown in Figure 2, this main line 41 includes L channel wire 60, R channel wire 70, earth lead 80, protective layer 411 and sleeve pipe 412, and this protective layer 411 is arranged in sleeve pipe 412.This sleeve pipe 412 is transparent material, this protective layer 411 is TPE(thermoplastic elastomer (TPE)) material, it has flexibility and elasticity, the cross sectional shape of this protective layer 411 is not limit, in the present embodiment, the cross section of this protective layer 411 is circular, certainly, the cross section of this protective layer 411 also can be triangle (as shown in Figure 3), because triangle is not yielding, have firm, firm, withstand voltage feature, thus can the L channel wire 60 of available protecting inside, R channel wire 70 and earth lead 80, and cross section can restore to the original state after to be leg-of-mutton protective layer 411 stressed fast, thus wire rod 40 is not easily tied a knot, thus solve the problem that traditional circular wire rod is easily wound around, and three of this protective layer 411 outer surfaces can arrange three kinds of different colors as required, so, wire rod 40 is made not only to have aesthetic feeling but also be rich in third dimension, meet modern young man to fashion, personalized pursuit.
A Y type separator 413 is provided with in this protective layer 411, the first cavity volume 401, second cavity volume 402 that the inside of protective layer 411 is divided into three to be isolated from each other by this Y type separator 413 and the 3rd cavity volume 403, L channel wire 60, R channel wire 70 and earth lead 80 are arranged in the first cavity volume 401, second cavity volume 402 and the 3rd cavity volume 403 respectively; So make L channel wire 60, R channel wire 70 and earth lead 80 be isolated from each other separately, thus avoid the mutual interference between L channel wire 60, R channel wire 70 and earth lead 80, reach the effect reducing noise.
This L channel wire 60, R channel wire 70 and earth lead 80 have included central hair 91, copper conductor 92, separator 93, insulating barrier 94 and screen 95, this copper conductor 92 is wound in outside central hair 91, this separator 93 is wrapped in outside copper conductor 92, this insulating barrier 94 is wrapped in outside separator 93, and this screen 95 is wrapped in outside insulating barrier 94.
In sum, design focal point of the present utility model is, it by being provided with a Y type separator in protective layer, the first cavity volume that the inside of protective layer is divided into three to be isolated from each other by this Y type separator, second cavity volume and the 3rd cavity volume, and coordinate L channel wire, R channel wire and earth lead are arranged at the first cavity volume respectively, in second cavity volume and the 3rd cavity volume, so make L channel wire, R channel wire and earth lead are isolated from each other separately, thus avoid L channel wire, mutual interference between R channel wire and earth lead, reach the effect reducing noise, effective raising sound quality.
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.
