Description
Technical field
It the utility model is related to a kind of cable, more particularly to a kind of audio-video signal transmission cable.
Background technology
The renewal progress of science and technology, promote society fast-developing, electronic information technology also shows swift and violent growth momentum.With
The development of information industry, the transmission of various information, signal, data increasingly shows the scene of numerous and complicated, at this stage,
Cable is the major way of current various information transfers, and important carrier of the cable as information transfer is all kinds of in order to ensure
The high-quality transmission of information, requirement to cable also more and more higher；It is well known that information by cable during can produce
Raw decay, and can be disturbed by other outside signals, therefore it is required that transmission yarn has function of shielding, to ensure information
High-quality transmission, the outer conductor of cable play shielding action, however, existing transmission yarn is due to technology usually as screen layer
The defects of, its shield effectiveness is unsatisfactory.
Existing audio network cable uses twisted pair wire, because of the impossible very little of the pair twist group lay of twisted pair wire, so externally
The interference of boundary's electromagnetic field can not reach higher shield effectiveness, and each pitch of the pair twist group of VON voice network winding thread is set because of its production
Standby, self structure constraint, it is difficult to reach its nominal value, i.e., the deviation of each pitch can be substantially limited within the scope of one, institute
Ideal shield effectiveness is unable to reach with the interference to external electromagnetic field；In addition, network each pair twist group of VON voice network winding thread
Pitch can because the condition lower part such as production, construction, mechanical collision lay can beyond pitch variation area requirement, cause to save
Shield effectiveness is had a strong impact on away from super deviation.The inner wire of single line of the network in each pair twist group of VON voice network winding thread, insulator
Deviation can have an impact to the performance of transmission, and deviation is bigger, and influence is also bigger.It can also be produced while external interference is produced
Transmission signal leaks, and causes the increase of signal attenuation, influences high-frequency signal transmission quality.
On the other hand, existing various transmission yarns are that function is single, structure is single, the transmission cable that separates independently of each other
Line, therefore, existing various transmission yarns in actual applications can not unify connect up, various information transfer cables in wiring just
Seem intricate, it is difficult to recognize, be unfavorable for managing, safeguard and repairing, and when producing cable, it is impossible to effectively optimize its life
Production. art, shorten technological process, therefore, its production cost is higher.
Utility model content
For drawbacks described above, the purpose of this utility model is to provide a kind of simple in construction, and manufacturing cost is low, shield effectiveness
A kind of audio-video signal transmission cable good, use range is wide.
Technical scheme is used by for this utility model：
Including video line, signal wire, power line, control line, light unit line, tone frequency channel wire and sheath, the jacket inner wall is set
There is screen layer, the video line, signal wire, power line, control line, light unit line and tone frequency channel wire are wrapped in inside screen layer,
Flexibility filler is provided between the video line, signal wire, power line, control line, light unit line and tone frequency channel wire and screen layer.
As the further improvement of above-mentioned technical proposal, the video line include set gradually inside-out inner wire,
Foaming insulation layer, shielding outer conductor and video line sheath, the shielding outer conductor is aluminium-plastic tape.
As the further improvement of above-mentioned technical proposal, the tone frequency channel wire includes some audio network twisted pair wires, the sound
The periphery of frequency network twisted pair wire is provided with tone frequency channel wire screen layer, and the tone frequency channel wire screen layer is externally provided with tone frequency channel wire sheath, the audio
Line screen layer is aluminium-plastic tape.
As the further improvement of above-mentioned technical proposal, the signal wire includes the pair of twisted cores set gradually inside-out
Line, signal wire screen layer and signal wire sheath, the signal wire screen layer are aluminium-plastic tape.
The utility model has the advantages that：
The utility model is simple in construction, and manufacturing cost is low, can realize audio-frequency information and video information and data message etc.
The transmission of much information so that the functional diversities of cable, shield effectiveness is good, and use range is wide.
