Description
Technical field
The utility model relates to a kind of data cable, relates in particular to a kind of water proof type high-speed data cable.
Background technology
Traditional high-speed data cable adds expanded polyolefin insulation by copper conductor, and to add the high-frequency signal that aluminium-plastic tape forms right, high-frequency signal to many pair sets stranding after wrapped polyester belt add aluminium-plastic tape, metal wire knitted shields, the PVC sheath.The structure that this kind is traditional is infiltrated through this gap moisture, because the moisture that outside cause causes the sheath cracking also can cause infiltrates owing to have the gap between the band easily.Long-term use can cause the increase of insulation decay, thereby influences the transmission of high-frequency signal.Moisture is not to the influence of high-frequency signal transmission when having in the existing product structure to consider long-term the use.Therefore, design a kind of moisture that stops effectively and infiltrate, have the performance of moisture absorption gas, and can guarantee that the high-speed data cable of cable insulation and high-frequency signal transmission stable performance becomes the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model provides a kind of water proof type high-speed data cable, and this high-speed data cable can stop effectively that moisture infiltrates, and has the performance of moisture absorption gas, thereby has guaranteed the stability of cable insulation and high-frequency signal transmission performance.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of water proof type high-speed data cable comprises: eight pairs of copper conductor lines of being made up of copper conductor are right, and this copper conductor is all outer to be covered with as the polyalkene foaming layer that insulate;
Polyolefin layer is overlying on this polyalkene foaming laminar surface outward;
It is right that the first plastic-aluminum combined layer is coated on said copper conductor line, and this first plastic-aluminum combined layer one side first plastic-aluminum combined another side of layer therewith melts the bonding connection of glue-line through low-temperature heat;
It is right that insulating barrier coats two pairs of copper conductor lines of said eight pairs of copper conductor line centerings, said eight pairs of copper conductor line centerings in addition six pairs of copper conductor lines to being covered on the said insulating barrier outside;
One teflin tape is wrapped, and six pairs of copper conductor lines are right in addition in said eight pairs of copper conductor line centerings;
Stack the composite bed that forms successively by first nonwoven layer, esters of acrylic acid mixture layer and second nonwoven layer and be coated on said teflin tape outer surface;
The second plastic-aluminum combined layer is coated on said composite bed outer surface;
The copper wire braid is coated on said second plastic-aluminum combined layer of outer surface;
One restrictive coating is coated on said copper wire braid outer surface.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said first, second plastic-aluminum combined layer is by laminated polyester film and be overlying on laminated polyester film Al thin film layer outward and form.
2, in the such scheme, said copper conductor surface is coated with a silver layer.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1, the utility model high-speed data cable is when the insulation heart yearn is extruded; Extrude one deck high density polyolefins material at the polyalkene foaming laminar surface; Form the fine and close coating layer of non-hygroscopic, prevented the polyalkene foaming laminar surface moisture absorption, strengthened the compression strength of polyalkene foaming layer structure simultaneously.
2, secondly; Teflin tape and stack the composite bed that forms successively by first nonwoven layer, esters of acrylic acid mixture layer and second nonwoven layer and form totally-enclosed water barrier; Increase is to the obstruct of moisture, and teflin tape has outstanding non-hygroscopic, and band can closely be attached under the effect of wrapped power and forms full-closed structure together; And teflin tape has the selfreparing characteristic; Stabbed to belting layer, after injurant was removed, band can be complete to guarantee with wound closure automatically.Simultaneously teflin tape also has outstanding insulation characterisitic, and waterstop is a nonwoven fabrics and water-absorbing resin is bonding is composited.When having moisture in the cable, water-absorbing resin absorbs moisture, and water-absorbing resin has the characteristic of imbibition, and the composite bed after the expansion can be full of the space in the cable, prevents the diffusion of moisture, blocks possible cable failure mouth simultaneously, prevents the further infiltration of moisture.The good non-hygroscopic of polytetrafluoroethylene belt also can prevent because the long-term existence of moisture and to the influence of the insulation characterisitic of primary insulation after the water blocking tape layer moisture absorption.
3, once more; The shielding that high-frequency signal is right applies one deck low temperature self-adhesion glue in advance with first, second plastic-aluminum combined layer; Just heat at signal production process; Make packaging material be bonded together and form the overall structure of sealing, thereby make signal, prevent the influence of moisture the expanded polyolefin insulation to forming core insulation surface compact coating layer and the bonding double sealing structure of aluminium-plastic tape; This aluminium-plastic tape that comprises the low temperature hot melt adhesive can closely coat high-frequency signal to reaching the cable combination of eight signals to forming simultaneously; In use twist and can guarantee to coat when crooked not loose, the stable stability characteristic (quality) that has also just guaranteed high-frequency signal transmission of this structure.
