Abstract
The utility model relates to an eight-pair digital voice-frequency cable. The cable comprises a line pair unit, fillers, a polyester film, a woven shielding layer and an outer polyvinyl chloride (PVC) sheath, wherein the line pair unit is formed in a manner that two conductors with polyethylene insulating layers are paired through twisting, and an earth wire, a polyester aluminum tape layer and an inner PVC sheath layer are sequentially arranged outside the conductors; and the filler layer, another seven line pair units, the polyester film layer, the woven shielding layer and the outer PVC sheath layer are sequentially arranged outside the line pair unit. The utility model has the advantages of excellent electrical performance, as well as higher signal transmission efficiency and cable operating frequency; PVC is used for insulation, so as to achieve small density and lower dielectric loss; due to the two-layer shielding structure, the overall shielding effect of the cable reaches above 99.1%, so as to effectively prevent electromagnetic interference; and the technique is simplified, and the industrial cost is lower than that of concentric weaving, so as to facilitate large-length production and post processing.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of eight pairs of digital voice-frequency cables.
Background technology
Current society, no matter be interconnection between the audio frequency apparatus, or the connection of music making equipment, acoustic playback equipment, all needing a kind of medium---voice-frequency cable, it is undertaking the transmission work of voice data.The quality of output tonequality directly has influence on audience's repercussion.Therefore, it is the target that we pursue that signal be can't harm transmission, and the sound superiority that the quality of digital audio is created usually is considerably beyond analogue audio frequency.The digital audio cable is to improve signal accuracy, transmits the cable of high-quality digital signal.
Summary of the invention
In view of the situation of prior art, this practicality provides a kind of eight pairs of digital voice-frequency cables.Characteristics such as this cable has that physical dimension compactness, dielectric loss are little, electric performance stablity, anti-electromagnetic interference, shield effectiveness height, signal transmission are good can satisfy the requirement of current marine exploration equipment.
The utility model is an above-mentioned purpose, the technical scheme of being taked is: a kind of eight pairs of digital voice-frequency cables, it is characterized in that: comprise the conductor pair twist that has polyethylene layer respectively by two, the line that sets gradually a ground wire, one deck polyester aluminium strip, one deck polyvinyl chloride inner sheath formation outside it is to the unit, also comprise filler, polyester film, woven shield and polyvinyl chloride oversheath, online to setting gradually one deck filler, seven lines outside the unit to unit, one deck polyester film, one deck woven shield, one deck polyvinyl chloride oversheath.
Advantage and the good effect that the utlity model has are: 1, superior electrical property: for improving effectiveness, the utility model selects for use soft round copper conductor to reduce the conductor decay, and the frequency of utilization of cable is improved, and the scope of application enlarges.2, dielectric loss is little: adopt polyethylene to do insulation, density is little, dielectric loss angle is little, superior performance.3, the cable shield effect is strong: the structure that adopts polyester aluminium strip (polyester/aluminium composite band) layer and two-layer shielding of screen of braiding outside it, the overall shield effectiveness of cable is reached more than 99.1%, prevent electromagnetic interference effectively, strengthened the cable shielding of electronic signal to external world.4, industrial cost is low, and be convenient to length production and back processing: internal shield adopts the polyester aluminium strip to replace braiding structure of the prior art, has promptly simplified technology, compares concentric weaving and has reduced industrial cost again.
Description of drawings
