Abstract

The utility model relates to a stereo sound audio data line. The stereo sound audio data line comprises two conductors, an insulating layer and an external coating layer, wherein the external coating layer is internally provided with the two conductors coated by the insulating layer, and the two conductors are twisted anticlockwise to form a group of twisted pair; and the stereo sound audio data line further comprises a wrapping layer, wherein the wrapping layer covers the twisted pair. According to the stereo sound audio data line, the wrapping layer is added, the twisted pair is covered by the wrapping layer, a return circuit is formed between the wrapping layer and the conductors, and the wrapping layer is good in shielding.

Description

A kind of stereo audio data line

Technical field

The utility model relates to a kind of network cable, particularly a kind of stereo audio data line.

Background technology

The stereo audio data line generally uses as earphone cord, is the cable commonly used of the equipment such as active loundspeakers.Development along with influence technique, people are also more and more higher to the requirement of stereo audio data wire, and the shield effectiveness of some the stereo audio data lines on the market is poor, and therefore poor anti jamming capability need to seek the good stereo audio data line of a shield effectiveness.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, provides a kind of and has preferably shield effectiveness, and stereo audio data line more attractive in appearance.

The technical scheme that realizes the utility model purpose is: a kind of stereo audio data line has conductor, insulating barrier and serving; Have two conductors that are coated with insulating barrier in the described serving; Described two conductors are turned round one group of twisted-pair cable of coiled pair counterclockwise; Also has lapping layer; Described lapping layer is coated on twisted-pair cable to upper.

The wrapping angle of the described lapping layer of technique scheme is 40～60 degree.

The described lapping layer of technique scheme is aluminium foil.

The technique scheme conductor is by 10 copper wire stranded compositions.

After adopting technique scheme, the utlity model has following positive effect:

(1) the utility model increases lapping layer; Lapping layer is coated on twisted-pair cable to upper; Form the loop between lapping layer and the conductor, and the shield effectiveness of lapping layer is good.

It is (2) of the present utility model that to make Wiring technology simple, good bandability, and antijamming capability is strong, and the signal transmission decay is few, and result of use is good.
