Description
Technical field
A kind of novel DeviceNet bus cables belong to technical field of electric wires and cables.
Background technology
As the type of industry spot underlying device is more and more, function is stronger and stronger, and traditional solution is not
Energy meet demand, maximum deficiency is exactly that I/O wiring quantities are too big, causes design, construction, maintenance workload big, costly
The problems such as.Although there is the buses such as Canbus, Profibus currently on the market, in manufacturing industry spot, DeviceNet
Bus sets the site intelligents such as programmable controller, operator terminal, sensor, photoswitc, motor starter, driver
It is standby to connect, it realizes networking and the remote management of industrial equipment, is that other buses are irreplaceable.
Novel DeviceNet bus cables are optimized and improve in structure and material.And use special process
Realize DeviceNet bus cables meet while transmission data cable under various circumstances needed for superior mechanical properties
And the characteristics such as towing, fire-retardant, oil resistivity.Flexible design power line group, to sharing drainage thread, is effectively reduced with data line
The outside diameter of cable, improves the economy and applicability of the bus cable.
Invention content
Economy and applicable performance effectively to reduce outside diameter of cable raising bus cable have developed a kind of novel
DeviceNet bus cables.
The product is achieved in the following ways：A kind of novel DeviceNet bus cables be by data line to,
Proof copper-wire braided always shields extrude sheath layer composition after source line group, the filling of drainage thread stranding, it is characterized in that data line pair and power supply
Line group distinguishes wrapped sub-shield.
Data line is to being constituted by extruding polyethylene foamed insulation outside tinned copper conductor.
Source line group is that thermoplastic elastomer (TPE) insulating layer composition is extruded outside conductor.
Separated-shielding uses the wrapped shielding of aluminium-plastic tape, total shielding to be constituted using tinned copper wire braid shielded.
Sheath is constituted using Special rubber plastic composition polymer.
Power line group is with data line to sharing a drainage thread.
Implementation in the above manner, the utility model patent technology have the advantages that：Novel DeviceNet is total
Line also provides power supply other than providing communication port.Therefore, in same cable, equipment can be from bus for power cord and signal wire
On directly acquire power supply, without external power supply；On the basis of traditional shielding mode, data line and power cord are respectively adopted
It absorbs the best aluminium-plastic tape of shielding attenuation to shield as internal layer, outer layer always shields use reflection loss effect best tin plating
Proof copper-wire braided material effectively enhances the shielding properties of cable；In order to ensure to transmit the data line pair and transmission electricity of digital signal
The source line group of stream is combined as an entirety, and power line group is made, to sharing a drainage thread, to reach reduction cable with data line
The purpose of outer diameter.
Description of the drawings
A kind of novel DeviceNet bus cables structural schematic diagrams of Fig. 1.
1. 4. power cord core insulation of data cable core conductor 2. data line core insulation, 3. power supply cable core conductor, 5. screen
Cover 6. drainage threads 7. filling, 8. 9. sheaths of shielding.
Specific implementation mode
1. conductor
Using regular twisted tinned copper conductor.The regular twisted outer diameter rule for making conductor, preferably to insulation core shift degree
It controls, conductor is tin plating to ensure that conductor is corrosion-resistant and high temperature resistance.
2, it insulate
To being insulated using polyethylene foamed, source line group is insulated data line using thermoplastic elastomer (TPE).
3, it shields
Separated-shielding uses the wrapped shielding of aluminium-plastic tape, total shielding to use tinned copper wire braid shielded.
4, sheath
Using Special rubber plastic composition polymer, ensure the spies such as high flexibility, high resiliency, corrosion-resistant, the low temperature resistant, Halogen of cable
Property.
