Abstract
The utility model discloses a data transmission cable for an automatic detection system. The data transmission cable comprises eight circular metal conductors, wherein outer surfaces of the eight circular metal conductors are respectively wrapped in an insulation layer, every two of the eight circular metal conductors are stranded to form a first wire stranding set, a second wire stranding set, a third wire stranding set and a fourth wire stranding set respectively, the first wire stranding set, the second wire stranding set, the third wire stranding set and the fourth wire stranding set are sequentially and parallelly arranged with intervals, outer surfaces of the first wire stranding set, the second wire stranding set, the third wire stranding set and the fourth wire stranding set are respectively wrapped in an elliptical foam insulation layer, the elliptical foam insulation layers of the adjacent wire stranding sets are connected through connection ribs, the elliptical foam insulation layers internally have multiple cavities, and the insulation layers are internally and circumferentially provided with multiple polyester fiber wires. The data transmission cable can easily reduce dielectric constants of the insulation layers, so transmission performance of the cable is improved, not only crosstalk of the cable is avoided, but also shedding of the cable caused by break of the cable fixed at a turning portion for a long time is further avoided.
Description
Technical field
The utility model relates to data cable field, is specifically related to a kind of automated detection system data cable.
Background technology
Communication cable not only can be because workmen's pulling force is excessive, undue force causes the pitch that cable inner wire is right to change because stretching in the time of construction wiring, thereby have influence on digital cable to every electric transmission performance, and the cable of this circular configuration is also unfavorable for indoor wiring and finishing.
The structure of cable: the structure of common cable is that single line as the circular configuration of sheath, is mainly laid in residence interior trims netting twine or computer local area machine room to use PVC after stranding through strand.
Due to the limitation of the said structure of cable, in residence interior trims netting twine or computer local area machine room, the wiring of cable and finishing bring many inconvenience, suffer distortion, bending, the digital cable processed roughly when construction, cause quality unstable, unreliable; Lack certain ability that prevents from affecting because of force-extension ability serviceability, repeatedly wiring has increased production cost, has increased heavy burden and the mounting and installation cost of building structure, has promotion prospect widely.
Summary of the invention
The utility model object is to provide a kind of automated detection system data cable, this data cable can easily reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improved the transmission performance of cable, prevent that cable cross-talk simultaneously, also prevent from causing broken string to come off because wire rod is fixed on turning point for a long time, frivolous good arrangement, is easy to storage and is easy to carry.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automated detection system data cable, comprise: eight circular metal conductors, this circular metal conductor outer surface is all coated with insulating barrier, described eight circular metal conductors are the stranded first twisted wire group that forms respectively between two, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group, the first twisted wire group, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group are arranged on parallel interval ground successively, the first twisted wire group, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group separately outer surface are all coated with oval foaming insulation layer, adjacent twisted wire group connects by dowel between oval foaming insulation layer separately,
If there is individual cavity in described oval foaming insulation layer, in described insulating barrier, circumferentially all have and be provided with some polyester fiber lines along it.
In technique scheme, further improvement project is as follows:
1. in such scheme, the flat telephone wire length of described high flexibility and height ratio are 10:1 ~ 2.
2. in such scheme, if the volume in described individual cavity accounts for 30 ~ 40% of whole oval foaming insulation layer volume.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model automated detection system data cable, can easily reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improved the transmission performance of cable, prevent that cable cross-talk simultaneously, also prevent from causing broken string to come off because wire rod is fixed on turning point for a long time, frivolous good arrangement, is easy to storage and is easy to carry; Secondly, compared with the digital cable of traditional circular configuration, this product can ensure that cable is without elongation strain, guarantee its transmission characteristic long-term stability, have again mechanical strength high, tensile strength is large, and coefficient of safety is higher, install, lay the advantages such as convenient, there is obvious economic benefit and promotional value.
Brief description of the drawings
Accompanying drawing 1 is the utility model automated detection system data cable structural representation.
In above accompanying drawing: 1, circular metal conductor; 2, insulating barrier; 3, the first twisted wire group; 4, the second twisted wire group; 5, the 3rd twisted wire group; 6, the 4th twisted wire group; 7, oval foaming insulation layer; 8, dowel; 9, cavity; 10, polyester fiber line.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: a kind of automated detection system data cable, comprise: eight circular metal conductors 1, this circular metal conductor 1 outer surface is all coated with insulating barrier 2, described eight circular metal conductors 1 are the stranded first twisted wire group 3 that forms respectively between two, the second twisted wire group 4, the 3rd twisted wire group 5 and the 4th twisted wire group 6, the first twisted wire group 3, the second twisted wire group 4, the 3rd twisted wire group 5 and the 4th twisted wire group 6 are arranged on parallel interval ground successively, the first twisted wire group 3, the second twisted wire group 4, the 3rd twisted wire group 5 and the 4th twisted wire group 6 separately outer surface are all coated with oval foaming insulation layer 7, adjacent twisted wire group connects by dowel 8 between oval foaming insulation layer 7 separately,
If have individual emptyly 9 in described oval foaming insulation layer 7, described insulating barrier 2 is interior circumferentially all to be had and is provided with some polyester fiber lines 10 along it.
The flat telephone wire length of above-mentioned high flexibility and height ratio are 10:1 ~ 2.
If above-mentioned individual empty 9 volume accounts for 30 ~ 40% of whole oval foaming insulation layer 7 volumes.
While adopting above-mentioned high reliability speech communication cable, can easily prevent from causing broken string to come off because wire rod is fixed on turning point for a long time, become good collocation invisible and tangible in cyberspace and the interior space.Finally, frivolous good arrangement of this wire rod, is easy to storage and is easy to carry.
