Abstract
The invention discloses a high-temperature-resistant instrument communication cable which is composed of conductors, insulators, filling ropes, a wrapping layer, wrapping sub-shielding, wrapping total shielding, a shielding body and a sheath. Two groups of cable cores formed by the insulators collectively wrap outside the conductors. One group of cable core is externally wrapped by the wrapping layer, and the other group of cable core is externally wrapped by the wrapping sub-shielding. The filling rope extrudes between the two groups of cable cores to form an integrated whole which is externally wrapped by the wrapping total shielding. The wrapping total shielding is externally extruded by the shielding body which is externally extruded by the sheath. The high-temperature-resistant instrument communication cable has the characteristics of being excellent in flame retardation, great in flexibility, high-temperature-resistant and high in anti-interference capability.
Description
Technical field
The present invention relates to field of cables, especially relate to a kind of communication cable of high-temperature-resinstrument instrument.
Background technology
At present, on hospital airport, large-scale Public Physical Education venue, public place of entertainment, colliery, the place such as iron and steel, traditional insulated cable can not meet the requirement of these places to space and weight, and these places are not provided safe and reliable there is superior flame retardant property, flexibility is good, high temperature resistant, the cable of the feature that antijamming capability is strong.The present invention is to cable insulation, and shielding, sheath material has done very large improvement, meets the demand of these places to cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one, to have flexibility good, high temperature resistant, the communication cable of high-temperature-resinstrument instrument that antijamming capability is strong.
The present invention takes following technical scheme to realize: a kind of communication cable of high-temperature-resinstrument instrument is made up of conductor, insulator, gasket for packing, lapping layer, wrapped separated-shielding, wrapped total shielding, shield and sheath.The outer group of described conductor is surrounded by described insulator and forms two groups of cable cores, described lapping layer is surrounded with outside one group of cable core, described wrapped separated-shielding is surrounded with outside another group cable core, be extruded with between two groups of cable cores that described gasket for packing group is in aggregates outer is extruded with described wrapped total shielding, be extruded with described shield outside described wrapped total shielding, outside described shield, be extruded with described sheath.
Described insulator adopts fluoroplastic insulation, and the thinnest point of monolateral insulation thickness 0.4mm insulation is not less than 0.35mm.
Described sheath adopts black heat-proof silastic material, and monolateral thickness 3.0mm, the thinnest point >=1.7mm, finished product overall dimension scope is 9.5 ~ 10.0mm.
The present invention has following beneficial effect in sum: structural design is compact, scientific and reasonable, conductor and be shielding for many silver-plated soft copper skein silks and close, can effectively prevent copper conductor to the aged catalyst effect of insulating barrier, to ensure the useful life of insulating barrier, the twisted wire pitch of pair twist group controls in lay≤40mm scope, screen adopts separated-shielding to be that the wrapped shielding of aluminium strip adds compound total shielding construction form, particularly total screen adopts braiding to add wrapped shielding construction, effectively improve the antijamming capability of cable, ensure that line capacitance is less than 500PF/100m, be applicable to instrument, Signal transmissions in instrument and other electric equipment and control circuit.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present invention;
Embodiment
As shown in Figure 1, a kind of communication cable of high-temperature-resinstrument instrument is made up of conductor 1, insulator 2, gasket for packing 3, lapping layer 4, wrapped separated-shielding 5, wrapped total shielding 6, shield 7 and sheath 8.Outer group of described conductor 1 is surrounded by described insulator 2 and forms two groups of cable cores, described lapping layer 4 is surrounded with outside one group of cable core, described wrapped separated-shielding 5 is surrounded with outside another group cable core, be extruded with between two groups of cable cores that described gasket for packing 3 groups is in aggregates outer is extruded with described wrapped total shielding 6, be extruded with described shield 7 outside described wrapped total shielding 6, outside described shield 7, be extruded with described sheath 8.
The present invention is so concrete enforcement: insulator 2 adopts fluoroplastic insulation, and the thinnest point of monolateral insulation thickness 0.4mm insulation is not less than 0.35mm.
Sheath 8 adopts black heat-proof silastic material, monolateral thickness 3.0mm, the thinnest point >=1.7mm, and finished product overall dimension scope is 9.5 ~ 10.0mm.
