Description

A kind of multi-functional compound cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of multi-functional compound cable.

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 existing 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 multi-functional compound cable, this compound cable is multiple cables such as integrated coaxial cable, electric power cable and network cable in the single line cable, avoid existing cable mixed and disorderly effectively, had defectives such as potential safety hazard, made things convenient for the layout and the maintenance of cable.

For achieving the above object, the technical solution adopted in the utility model is: a kind of multi-functional compound cable, and described recombination line cable wrap is drawn together the aluminium core, two first copper conductors and two second copper conductors;

Described aluminium core coats a bronze medal layer;

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, and a restrictive coating is overlying on this two second surface of insulating layer outward;

The polyester belt coats described copper layer, first insulating barrier and second surface of insulating layer;

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, the described second copper conductor diameter is 0.5 ± 0.002 mm.

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

The utility model is multiple cables such as integrated coaxial cable, electric power cable and network cable in the single line cable, have avoided existing cable mixed and disorderly effectively, and there are defectives such as potential safety hazard in difficult wiring, has made things convenient for the layout and the maintenance of cable, has 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.
