Abstract
A kind of light-duty data of the utility model transmit composite cable, and two power line units, a data wire unit and a ground wire are twisted bunchy, in its outer successively wrapped one layer of bundle yarn, are woven with the total shielded layer of one layer of copper-clad aluminum alloy, extrude one layer of TPE elastomer sheath；Data line unit includes copper-clad aluminum alloy conductor inner conductor I, foamed low density polyethylene layer, copper-clad aluminum alloy sub-shield, one layer of foamed low density polyethylene layer is extruded outside copper-clad aluminum alloy conductor inner conductor I and constitutes data line, weaves one layer of copper-clad aluminum alloy sub-shield outside two data lines；Power line unit is constituted by extruding one layer of TPE elastomer insulating layer outside copper-clad aluminum alloy conductor inner conductor II.The utility model is characterized in that: the structure of the cable designs, data transmission attenuation is reduced, reduces power supply signal transmission is influenced, alleviates cable overall weight about 8%, and improves high frequency lower conductor utilization efficiency.
Description
Technical field
The utility model relates to a kind of light-duty data to transmit composite cable, be a kind of light electric and data signal transmission
Composite cable.
Background technique
Data transmission composite cable is a kind of cable for data transmission, communication, can be attached and lead in equipment room
News.Aggregation of data cable on existing market is designed mainly for specific environment, since data transmission comprehensive cable wants decaying
Ask high, and power supply unit has certain influence to signal transmission, it is complicated to cause existing cable design structure, including fill out core, multilayer screen
It covers.And due to mostly using tin plating copper stranded conductor or silver-plated copper stranded wire as conductor, overall weight is big, cost is high, line footpath is larger.For
The market demand needs to develop a kind of light-duty data transmission composite cable.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of light-duty data transmission composite cable, the electricity
The structure of cable designs, and reduces data transmission attenuation, reduces power supply and influence on signal transmission, alleviate cable overall weight about
8%, and improve high frequency lower conductor utilization efficiency.
To achieve the above object, used technical solution is the utility model: a kind of light-duty data transmission composite cable,
It is characterized by comprising data line unit, power line unit, ground wire, prick yarn, total shielded layer, sheath；
Two power line units, a data wire unit and a ground wire are twisted bunchy, in its outer successively wrapped one layer of bundle
Yarn is woven with the total shielded layer of one layer of copper-clad aluminum alloy, extrudes one layer of TPE elastomer sheath；
The data line unit includes copper-clad aluminum alloy conductor inner conductor I, foamed low density polyethylene layer, copper clad aluminum
Alloy sub-shield extrudes one layer of foamed low density polyethylene layer outside copper-clad aluminum alloy conductor inner conductor I and constitutes data
Line, two data lines weave one layer of copper-clad aluminum alloy sub-shield outside；
The power line unit is constituted by extruding one layer of TPE elastomer insulating layer outside copper-clad aluminum alloy conductor inner conductor II.
The utility model is characterized in that: the product is the structure of data line and power supply line generalization, in order to mitigate cable weight,
High frequency cable conductor utilization efficiency is improved, copper-clad aluminum alloy conductor is used.In order to solve data transmission comprehensive cable transmission attenuation
Greatly, power supply has the problem of certain influence to signal transmission, and data line uses foamed low density polyethylene layer, guarantees simultaneously
The outside diameter of cable is small, density is low, reduces insulating materials dielectric constant, improves signaling rate.To avoid power supply demand pairs evidence
Line transmits the influence of signal, has individually carried out copper-clad aluminum alloy separated-shielding to data line.It is risen using the total shielded layer of copper-clad aluminum alloy
To fixed function, mitigate weight.For the flexibility for increasing power transmission capacity, improving cable, flame retardant effect, power supply line are had both
Using TPE elastomer insulating layer, restrictive coating.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the data line unit structural schematic diagram of the utility model；
Fig. 3 is the power line unit structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of light-duty data transmit composite cable, including data line unit 1, power line unit
2, ground wire 3, bundle yarn 4, total shielded layer 5, sheath 6.
Data line unit 1 includes I 1-1 of copper-clad aluminum alloy conductor inner conductor, foamed low density polyethylene layer 1-2, copper
Alclad alloy sub-shield 1-3 extrudes one layer of foamed low density polyethylene insulation outside I 1-1 of copper-clad aluminum alloy conductor inner conductor
Layer 1-2 constitutes data line, weaves one layer of copper-clad aluminum alloy sub-shield 1-3 outside two data lines.
Power line unit 2 is by extruding one layer of TPE elastomer insulating layer 2-2 structure outside II 2-1 of copper-clad aluminum alloy conductor inner conductor
At.
Two power line units 2, a data wire unit 1 and a ground wire 3 are twisted bunchy, successively wrapped one outside it
Layer pricks yarn 4, is woven with the total shielded layer 5 of one layer of copper-clad aluminum alloy, extrudes one layer of TPE elastomer sheath 6.
