Description

A kind of recombination line cable structure with tensile property

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of recombination line cable structure with tensile property.

Background technology

Along with the high speed development of data communication and information technology, the improving constantly of the fast development of network technology and computing power, user's home terminal type is more and more, and this is also more and more higher to the comprehensive wiring system performance demands.Network rate improves day by day, means the raising of operating frequency, is easy to generate electromagnetic radiation and capacitive coupling more.Simultaneously, can constantly there be new electromagnetic interference source to produce in the surrounding environment, the radiation of the high more generation of network work frequency is also serious more, and the equilibrium response of the non-shadow data cable of UTP has been not enough to offset the electromagnetic radiation and the extraneous electromagnetic interference (Electro Magnetic Compatibility in the time of only satisfying 30～40MHz transfer of data) of express network itself.

In our existing comprehensive wiring system, general use that 4 pairs of ordinary numbers cables are surfed the Net, transfer of data etc., use local cable to advance wiring can to carry out the transmission of phone, voice etc., use common coaxial cable to carry out watching of Web TV, HDTV (High-Definition Television) etc., above cable need influence each other in same pipeline concentric wiring, the phase mutual interference in wiring.

Because the said structure of cable and the limitation of wiring, therefore along with the influence when the high-frequency of electromagnetic radiation and capacitive coupling is more and more outstanding, had a strong impact on the electric property of each cable, cause each cable comprehensive wiring behind the family, the definition of the networking speed of family, telephone relation quality, high definition picture etc. all can be subjected to influence in various degree, and because each cable all is separate unit, throughout the year month after month send out temperature, hot after, cause each cable sheath inter-adhesive etc. easily, finally cause brokenly skin even electric leakage, burning, final initiation fire.

Summary of the invention

The utility model provides a kind of recombination line cable structure with tensile property, this recombination line cable structure is in the single line cable in integrated coaxial cable, electric power cable and the network cable, increase the fatigue resistance and the twisting resistance of cable, and avoided existing cable mixed and disorderly effectively.

For achieving the above object, the technical solution adopted in the utility model is: a kind of recombination line cable structure with tensile property, described recombination line cable wrap are drawn together aluminium core, two first copper conductors and two second copper conductors and gasket for packing;

Described aluminium core coats a bronze medal layer, and this copper layer is coated with to have as if an insulation foaming layer in cavity, and this is if an empty volume accounts for 50% of whole insulation foaming layer volume;

Described two first copper conductors all are coated with first insulating barrier separately, and a single face first aluminium foil layer coats this two first insulating barriers;

Described two second copper conductors all are coated with second insulating barrier separately, this two second parallel placements of insulating barrier and be " ∞ " font and place, and a restrictive coating is overlying on this two second surface of insulating layer outward;

The polyester belt coats described insulation foaming layer, first insulating barrier, second insulating barrier and gasket for packing surface;

Second aluminium foil layer coats described polyester belt;

Flame-retardant layer is coated on the described second aluminium foil layer outer surface.

Related content in the technique scheme is explained as follows:

1, in the such scheme, described second aluminium foil layer is two-sided aluminium foil layer.

2. in the such scheme, described gasket for packing area of section is 0.50～1.0mm ²

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

The utility model is integrated coaxial cable, electric power cable and the multiple cable of network cable in the single line cable, the fatigue resistance and the twisting resistance of cable have been increased, avoided existing cable mixed and disorderly effectively, difficult wiring, there are defectives such as potential safety hazard, make things convenient for the layout and the maintenance of cable, reduced potential safety hazard; Secondly, adopt the polyester belt that whole cable unit is carried out dampproof effect, fastening whole cable unit, and improve the insulation property of whole cable to the full extent.
