Abstract
The utility model discloses a coaxial data transmission composite cable comprising an aluminum core and two copper wires. The aluminum core is wrapped in a copper layer which is wrapped in an insulating foaming layer. The two copper wires are wrapped in an insulating layer, respectively. An inner sheath layer is wrapped round the outer surfaces of the two insulating layer. A separating plate is arranged between the inner sheath layer and the insulating foaming layer. Leaf bud sheets are disposed on the two ends of the separating plate. A first cavity and a second cavity are formed by the separating plate and the corresponding leaf bud sheets on the two ends of the separating plate. The inner sheath layer and the insulating foaming layer are arranged in the first cavity and the second cavity, respectively. A polyester tape layer is wrapped round the inner sheath layer, the insulating foaming layer, and the separating layer. A single-side aluminum foil layer is wrapped round the polyester tape layer. The coaxial data transmission composite cable prevents unqualified product performance caused by unstable wire pair position in the twisting process and substantially enhances a capability of preventing humidity and moisture from entering the interior of the cable, the humidity and moisture influencing using performance of the 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 requirement to the comprehensive wiring system performance is also more and more higher.Network rate improves day by day, means the raising of operating frequency, more easily produces electromagnetic radiation and capacitive coupling.Simultaneously, can constantly there be new electromagnetic interference source to produce in surrounding environment, the radiation of the higher generation of network operating frequency is also more serious, and the equilibrium response of the non-shadow data cable of UTP has been not enough to offset 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 to influence each other in same pipeline concentric wiring, the phase mutual interference in wiring.
Due to the said structure of cable and the limitation of wiring, therefore the impact when the high-frequency is more and more outstanding along with electromagnetic radiation and capacitive coupling, 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 subject to impact in various degree, and because each cable is all separate unit, throughout the year month after month send out temperature, hot after, easily cause each cable sheath inter-adhesive etc., finally cause broken skin, even leak electricity, burn, final initiation fire.
Summary of the invention
The utility model provides a kind of coaxial data transmission composite rope, and this coaxial data transmission composite rope can prevent that in the process of twisting, line is unstable to the position, causes properties of product defective; And greatly having strengthened cable, to prevent that moisture, moisture from entering cable inner and affect the ability of serviceability.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coaxial data transmission composite rope comprises aluminium core and two copper conductors; One bronze medal layer coats described aluminium core, and an insulation foaming layer coats described copper layer;
Described two copper conductors all are coated with insulating barrier separately, and a sheath coats this two insulating barrier outer surfaces;
One division board is between described sheath and insulation foaming layer, and this division board two ends are equipped with the leaf bud sheet; The corresponding leaf bud sheet in division board and its two ends forms the first cavity and the second cavity thus, and described sheath and insulation foaming layer lay respectively in the first cavity and the second cavity;
One polyester belt coats described sheath, insulation foaming layer and division board;
Be filled with the colloid elastomer as waterproof paste in described the first cavity and the second cavity between described polyester belt and described sheath, insulation foaming layer;
One single face aluminium foil layer coats described polyester belt;
External sheath layer coats described single face aluminium foil layer.
Related content in technique scheme is explained as follows:
In such scheme, a drain wire is between described polyester belt and single face the second aluminium foil layer, and this drain wire single face the second aluminium foil layer therewith conducts connection.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model coaxial data transmission composite rope, a division board are between described sheath and insulation foaming layer, and this division board two ends are equipped with the leaf bud sheet; The corresponding leaf bud sheet in division board and its two ends forms the first cavity and the second cavity thus, can prevent that in the process of twisting, line is unstable to the position, causes properties of product defective; Secondly, it is integrated coaxial cable and the multiple cable of power cable in the single line cable, has effectively avoided existing cable mixed and disorderly, and there are the defectives such as potential safety hazard in difficult wiring, has facilitated layout and the maintenance of cable, has reduced potential safety hazard; Again, be filled with the colloid elastomer as waterproof paste in the first cavity and the second cavity between described polyester belt and described sheath, insulation foaming layer, greatly strengthened cable and prevented that moisture, moisture from entering cable inside and affecting the ability of serviceability.
