Abstract
The invention discloses a high-temperature-resistant dragging-resistant double-shielding coaxial cable for computers. The high-temperature-resistant dragging-resistant double-shielding coaxial cable comprises a center conductor, an outer conductor, an inner shielding layer, an insulating layer, an outer shielding layer and a protective jacket. A skinning layer is arranged between the center conductor and the outer conductor and made of plastic rubber, expanded perlite powder and graphite particles are added in the plastic rubber, a grounded cable core is wrapped by the insulating layer, the grounded cable core is formed in the mode that a plurality of annealing copper aluminum alloy wires with the nickel-plated surfaces are wrapped by thin steel wires in an up-and-down overlapping and twisting mode, the position between the outer shielding layer and the protective jacket is wrapped by a metal layer, the protective jacket is made of chlorosulfonated polyethylene, and ceramic fibers and oil-proofing agents are added in the chlorosulfonated polyethylene. The high-temperature-resistant dragging-resistant double-shielding coaxial cable has the advantages of being good in electrical conductivity and resistant to high temperature and bending, being widely applied to the fields such as computers and communication, being good in shielding effect and resistant to oil and water, and meanwhile being resistant to dragging and oxidation.
Description
Technical field
The invention belongs to field of cables, relate in particular to the high temperature resistant anti-double shielded coaxial cable that pulls for a kind of computer.
Background technology
At present, along with developing rapidly and the raising day by day of scientific and technological level of Chinese national economy, accelerate the growth of cable consumption, equally the quality requirement of cable has also constantly been improved.Such as the cable using in the field such as computer, communication, shielding anti-jamming effectiveness is even more important, same, high temperature resistant, the waterproof oil resistant of cable, and the anti-performance such as pull is very important equally.Only meet the requirements, just can better guarantee the requirement of the actual use of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind ofly conduct electricity very well, waterproof oil resistant, high temperature resistant, double shield, the anti-computer pulling prevent pulling double shielded coaxial cable with high temperature resistant.
The present invention takes following technical scheme to realize: a kind of computer is prevented pulling double shielded coaxial cable with high temperature resistant, and it comprises center conductor, outer conductor, internal shield, insulating barrier, outer shielding layer and protective sleeve.Between described center conductor, described outer conductor, be provided with skinning cortex; described skinning cortex is by the plastic, rubber that adds expanded pearlite Rock Powder, graphite granule; described insulating barrier internal package ground connection core; described ground connection core be by the annealed copper aluminum-alloy wire outsourcing finer wire of some strands of plating nickel on surface, stranded the forming that superpose up and down; coated metal layer between described outer shielding layer and described protective sleeve, described protective sleeve material is to add the chlorosulfonated polyethylene of ceramic fibre, oil-proofing agent.
Described internal shield and described outer shielding layer are the outer aluminium foil braiding of magnesium rod and form.
Described metal level is by steel wire outsourcing silicon rubber, according to 18/0.5(root/square millimeter) ratio is stranded forms.
The present invention has following beneficial effect in sum: this cable conduction performance is good, high temperature resistant, resistance to bending, is mainly used in the field such as computer, communication, and shield effectiveness is good, and oil resistant waterproof also possesses anti-pulling, oxidation resistant advantage simultaneously.
