Abstract
The utility model relates to a multi-core control and communication compound cable which comprises an outer jacket, a total shield, a power supply line pair, a control line and a data signal line pair. The total shield is coaxially installed in the outer jacket, and the control line, the data signal line pair and the power supply line pair are coaxially installed in the total shield. The cable is characterized in that the data signal line pair is externally sleeved with a branch shield, an external shield is coaxially sleeved outside the control line, and the control line, the power supply line and the data signal line pair are hinged and arranged in an intersected manner. According to the compound cable provided by the utility model, the cross-sectional area of conductor, the insulating thickness, the outer diameter of the cable, the transmission length, the using frequency and the characteristic impedance are designed according to technical indexes, so that the cable has the longest transmission distance on the premise that the transmission frequency and the characteristic impedance are satisfied.
Description
Technical field
The utility model belongs to field of cables, relates to telecommunication cable, and especially a kind of multicore is controlled, communication composite cable.
Background technology
Development along with science and technology, in the device transmission network system, need a while one transmission control and information data, while to reach at a high speed control, the signal cable of field network, this cable can reach at a high speed field network with control and information data, is used for Comprehensive Control, the transmission of equipment.
At present, not yet find the private cable of this mode.
The utility model content
The purpose of this utility model is to provide a kind of multicore control, communication composite cable, and the electronic equipment that this cable is applicable to field network system connects, and the high-speed transfer information data.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of multicore is controlled, communication composite cable, comprise that oversheath, total shielding, power line are to, control line and data signal line pair, in oversheath, coaxial installation always shields, coaxial installation control line, data signal line are to reaching power line pair in total shielding, it is characterized in that: described data signal line has separated-shielding to overcoat, the outer coaxial sleeve of control line has external shield, and control line, power line and data signal line are arranged adopting to intersect to twist to fill.
And described total shielding, external shield and separated-shielding all adopt the plastic-aluminum combined film of polyester to add the braid shielded structure.
And the low density polyethylene (LDPE) insulating barrier is all adopted in the insulation of described control line, power line and data signal line.
And described oversheath adopts 105 ℃ of fire-retardant, oil resistants, heat-resistant polyvinyl chloride sheath.
Advantage of the present utility model and beneficial effect are:
1, the cross-sectional area of conductor of this composite cable, insulation thickness, the outside diameter of cable, transmission length, frequency of utilization and characteristic impedance design according to technical indicator, have guaranteed that cable has the longest transmission range satisfying under transmission frequency and characteristic impedance.
2, low-density polyethylene material is adopted in the insulation of this composite cable, can guarantee that cable does not sharply increase in the loss of high-frequency transmission process medium, transmission frequency bandwidth, simultaneously cable is transmitted under different frequency, stable signal transmission, dielectric loss is little, and electrical property is excellent, guarantees that the signal data transmission speed is fast.
3, the data signal transmission wire pair twist pitch of this composite cable is set according to transmission frequency, has guaranteed that cable is soft; Control line and many arrangement architectures that data signal line is intersected to employing, reduced the crosstalk attenuation that signal produces between data wire in transmitting procedure, guaranteed with cable transmission various control signal and data-signal, applicable to the various high transmission systems of Comprehensive Control that need, reduce simultaneously the cost of cable, satisfied the requirement of mounting and installation.
4, right shielding and the total shielding of cable of the data-signal of this composite cable transmission all adopts spiral winding polyester aluminum-plastic composite membrane to add the braid shielded form, greatly improved the right antijamming capability of cable data signal, signal interference and control line and the extraneous interference that data wire is caused between data wire pair have effectively been avoided, spiral winding adds the braid shielded form and has greatly improved the cable flexibility, has improved simultaneously the shielding properties of cable.
5, this composite cable uses 105 ℃ of fire-retardant, oil resistants, heat-resistant polyvinyl chloride sheath, has increased fail safe and the reliability of cable installation, has improved cable useful life.
