Description

High definition sound wire

Technical field

The present invention relates to a kind of sound wire, particularly a kind of high definition sound wire.

Background technology

In stereo set, the effect of sound wire is to couple together each several part of sound equipment, transmits audio signal.Current sound wire is generally by outermost insulating materials protective layer（As PVC）, positioned at the wire at center（Generally formed by the tiny wire stranding of multiply）And connection terminal composition, additionally, a lot of sound wire plus covers layer of metal screen layer also between wire and insulating barrier, to shield the interference in the external world.

Audio signal is during wire transmission, there is mutual electromagnetic interference between the wire constituting signal transmission loop, and between the tiny wire of multi beam forming each wire, also can there is mutual electromagnetic interference, in the design process of sound wire, conductor material, tiny wire count and the selection of twisting arrangement mode, the factors such as the cladding of insulating materials determine the degree that signal transmission is subject to electromagnetic interference influence, electromagnetic interference can greatly be reduced by sound wire reasonable in design in these areas, thus realizing the high definition transmission of signal, otherwise the serious problems such as distorted signals or even loss then occur, largely effect on laser propagation effect.With the continuous expansion to high-end acoustic product demand for the people, consumer is put forward higher requirement with outward appearance to the quality of sound wire, and existing sound wire above-mentioned aspect design Shortcomings it is impossible to meet consumer demand.

Content of the invention

Make improvements in the deficiency existing for prior art, the technical problem to be solved is to provide a kind of transparent high definition sound wire, not only attractive in appearance but also the mutual electromagnetic itself producing in signals transmission interference greatly can be reduced, realize the transmission of signal high definition.

For solving above-mentioned technical problem, the technical scheme is that：A kind of high definition sound wire, including the protective layer of conductor portion and the insulation being coated on outside conductor portion；Described conductor portion includes the first conductor and the second conductor, described first conductor is formed by multiply bare copper wire and multiply tinned copper wire bundle strand with described second conductor, and the quantity of bare copper wire that comprises in described first conductor is equal with the quantity of the tinned copper wire comprising in described second conductor, the quantity of tinned copper wire comprising in described first conductor is equal with the quantity of the bare copper wire comprising in described second conductor；Described protective layer is coated on outside described first conductor and described second conductor.Described bare copper wire and tinned copper wire are the superfine copper free wire of 4n, and the diameter of per share copper wire is respectively less than or is equal to 0.12mm, and signal transmission effect is good.Described first conductor central authorities are provided with one tinned copper wire, and the bare copper wire of described first conductor and remaining tinned copper wire are alternately about around the tinned copper wire in described first conductor central authorities；Described second conductor central authorities are provided with one bare copper wire, and the bare copper wire of described second conductor and remaining tinned copper wire are alternately about around the bare copper wire in described second conductor central authorities.This structure of conductor utilize wire stranding copper wire number of share of stock difference, formed sound wire use when loop formed wait resistance, etc. electric capacity, can at utmost reduce interfering in signals transmission it is ensured that transmitting high definition tonequality.In twisting, all bare copper wires of described first conductor and tinned copper wire take " S " to stranded；All bare copper wires of described second conductor and tinned copper wire take " Z " to stranded.This stranded mode can make the direction of lay of two wires contrary, producing contrary curling test respectively, thus mutually suppressing the curling of other side, preventing sound wire from crimping knotting in use.

Described first conductor and the second conductor are all coated in described protective layer, and described first conductor and described second conductor are parallel to each other.Using this cladding mode can material-saving, the sound wire Stability Analysis of Structures made, good looking appearance.

Described protective layer is transparent, is made using the PVC material being added with antioxidant, not only attractive in appearance, and improves the oxidation resistance of conductor, enhances the transmission performance of high definition sound wire.

Specific embodiment

Referring to figs. 1 to Fig. 3, the present invention is implemented：

In FIG, a kind of high definition sound wire, including the protective layer of conductor portion and the insulation being coated on outside conductor portion；Described conductor portion includes the first conductor and the second conductor, described first conductor is twisted together by multiply bare copper wire and multiply tinned copper wire with described second conductor, and the quantity of bare copper wire that comprises in described first conductor is equal with the quantity of the tinned copper wire comprising in described second conductor, the quantity of tinned copper wire comprising in described first conductor is equal with the quantity of the bare copper wire comprising in described second conductor；Described protective layer is coated on outside described first conductor and described second conductor.

In fig. 2, the first conductor is made up of 4 strands of tinned copper wires of diameter identical and 3 strands of bare copper wires, and the first conductor central authorities are one tinned copper wire, and bare copper wire and remaining tinned copper wire are alternately about around central tinned copper wire；First conductor takes " S " to stranded in twisting.

In figure 3, the second conductor is made up of 3 strands of tinned copper wires of diameter identical and 4 strands of bare copper wires, and the second conductor central authorities are one bare copper wire, and tinned copper wire and remaining bare copper wire are alternately about around central bare copper wire；Second conductor takes " Z " to stranded in twisting.
