Description

It is a kind of mobile to use digital audio line

Technical field

The utility model is related to technical field of electric power, specially a kind of movement uses digital audio line.

Background technology

Tone frequency channel wire is for transmitting audio signal, is a kind of coaxial cable for transmitting audio base-band analog signal. The transmission signal of video line need to carry function of shielding, and it is to ensure the transporting of the system in the case where there is electromagnetic interference environment to shield Can, anti-interference here should include two aspects, that is, resist extraneous electromagnetic interference ability and system itself to external radiation The ability of electromagnetic interference.Theoretically, it in cable and connector appearance packet last layer metal material shielded layer, can effectively filter Except unnecessary electromagnetic wave, but the effect of common video line shielding is not fine, and the connection of its interlayer is not sufficiently stable, The insufficient strength of conducting wire, therefore we have proposed a kind of movements to use digital audio line.

Utility model content

The purpose of this utility model is to provide a kind of movements to use digital audio line, to solve to carry in above-mentioned background technology The problem of going out.

To achieve the above object, the utility model provides the following technical solutions：It is a kind of mobile using digital audio line, including Conductor and restrictive coating, the outside of the conductor, which is equipped with, is enclosed with copper sheet, and insulating layer, the insulation are enclosed on the outside of the copper sheet The outside of layer is enclosed with shielded layer, and the first aluminium foil layer is inlaid in the middle part of the shielded layer, is inlaid in the middle part of the restrictive coating Second aluminium foil layer is equipped with reinforcer between the restrictive coating and shielded layer.

Preferably, the conductor is equipped with 3, and the conductor strand is arranged in the middle part of copper sheet.

Preferably, the restrictive coating is specially polyvinyl chloride layer, and the insulating layer is specially polyethylene layer, the shielded layer Specially tinned copper wire woven shield.

Preferably, for the reinforcer at least provided with 6, the reinforcer circular array is arranged in restrictive coating and shielded layer Between, there is traction-resistant fibre item in the middle part of the reinforcer..

Compared with prior art, the utility model has the beneficial effects that：The movement uses digital audio line, by being equipped with the The structure of one aluminium foil layer and the second aluminium foil layer can completely cut off external interference signal, greatly increase digital audio Line ensure that the stability that digital audio line signal transmits to the isolation effect of external interference signals；By equipped with reinforcer Structure can greatly enhance the intensity and toughness of digital audio line.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：It is a kind of mobile using digital audio line, including lead Body 1 and restrictive coating 5, conductor 1 is in order to transmit signal and electric energy so that each component can be connected with each other, and ensure that equipment Normal work, the conductor 1 is equipped with 3, the twisted middle part for being arranged in copper sheet 2 of the conductor 1.Copper sheet 2 enables to conductor 1 It transmits signal and electric energy more to stablize, the outside of the conductor 1, which is equipped with, is enclosed with copper sheet 2, the outside package of the copper sheet 2 There are insulating layer 3, insulating layer 3 to avoid the leakage of electric energy, cause the accident, while conductor 1 also being protected not to be damaged, it is described exhausted The outside of edge layer 3 is enclosed with shielded layer 4, and shielded layer 4 transmits progress to shield external interference signal to the signal of conductor 1 Interference, the shielded layer 4 are specially tinned copper wire woven shield, and tinned copper wire is woven with insulating layer, and effect is to prevent electric current It radially leaks, guarantee is safe to use, has good electrical insulation capability.The middle part of the shielded layer 4 is inlaid with the first aluminium foil Layer 6, the first aluminium foil layer 6 can greatly increase the effect that shielded layer 4 shields external interference signals, the middle part of the restrictive coating 5 It is inlaid with the second aluminium foil layer 7, the second aluminium foil layer 7 can for the first time completely cut off external interference signal, the restrictive coating 5 Specially polyvinyl chloride layer, for restrictive coating 5 in order to protect conductor 1 and each layer, the insulating layer 3 is specially polyethylene Layer, the shielded layer 4 are specially tinned copper wire woven shield.Reinforcer 8 is equipped between the restrictive coating 5 and shielded layer 4, At least provided with 6,8 circular array of the reinforcer is arranged between restrictive coating 5 and shielded layer 4 reinforcer 8, described to add 8 middle part of strong part has traction-resistant fibre item.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
