Abstract

The invention discloses a dragging-resistant double-shielding strengthened multi-core coaxial cable for a computer. The dragging-resistant double-shielding strengthened multi-core coaxial cable comprises a coaxial cable core, a strengthened piece, a taping layer, an inner shielding layer, an outer shielding layer and a protective jacket. The strengthened piece is characterized in that three insulating plates are intersected in the center of the taping layer, the taping layer is evenly divided into three window panes, the coaxial cable core is wrapped inside the window panes of the the strengthened piece, the periphery of the coaxial cable core is respectively tangent with the taping layer and the strengthened piece, an insulating layer is arranged between the inner shielding layer and the outer shielding layer, a copper wire drainage cable and a grounded cable core are wrapped by the insulating layer, and the position between the outer shielding layer and the protective jacket is wrapped by a metal layer. The dragging-resistant double-shielding strengthened multi-core coaxial cable is good in electrical conductivity, long in service life, resistant to high temperature, fireproof and resistant to drag, is widely applied to the fields such as electricity generation, metallurgy, petroleum and chemical engineering, is resistant to oxidation and high in shielding performance, and meanwhile is firm in cable core.

Description

A kind of computer is strengthened multicore coaxial cable by the anti-double shield that pulls

Technical field

The invention belongs to field of cables, relate in particular to the anti-double shield that pulls of a kind of computer and strengthen multicore coaxial cable.

Background technology

At present, along with the raising day by day of China's rapid development of economy and scientific and technological level, the consumption of cable constantly increases, and the quality of cable is also proposed to higher requirement.But present general cable shield performance is not high, anti-pull a series of problems such as strong or core is firm not.Just can better meet the actual service condition of cable as long as improve the combination property 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 of high temperature resistant grease proofing, excellent and anti-the pulling of shielding insulation performance, core is the anti-double shield reinforcement multicore coaxial cable that pulls for computer firmly.

The present invention takes following technical scheme to realize: a kind of computer is strengthened multicore coaxial cable by the anti-double shield that pulls, it comprises coaxial core, reinforcement, belting layer, internal shield, outer shielding layer and protective sleeve, described reinforcement is to intersect at described belting layer center by three insulation boards, described belting layer is divided into three panes, described coaxial core is wrapped in the pane inside of described reinforcement, described coaxial core circumference respectively with belting layer, described reinforcement is tangent, between described internal shield and described outer shielding layer, be provided with insulating barrier, three copper wire drainage threads of described insulating barrier internal package, a ground connection core, coated metal layer between described outer shielding layer and described protective sleeve.

Described coaxial core is three groups, and described coaxial core is made up of the outer conductor of the outer aluminium foil braiding of cobalt plating fine copper inner wire, skinning cortex and steel wire.

Described metal level is to be to mould by the zinc-plated anaerobic steel wire of 98.40% annealing outsourcing fluorine the polyurethane that described protective sleeve material is organic silicon ribbon of containing mica, graphite, antioxidant by described metal level.

Described protective sleeve material is the polyurethane of organic silicon ribbon of containing mica, graphite, antioxidant.

The present invention has following beneficial effect in sum: good conductivity of the present invention, and long service life, fire resistant, anti-pulling, is widely used in generating, metallurgy, oil, chemical industry, light

The detection of Fang Deng department and control computer system or automation equipment, and on general industrial computer, anti-oxidant, shielding properties is strong, core is firm simultaneously, can effectively prevent extraneous extruding and does not depart from former desired location.

Embodiment

As shown in Figure 1, a kind of computer is strengthened multicore coaxial cable by the anti-double shield that pulls, it comprises coaxial core 2, reinforcement 1, belting layer 3, internal shield 4, outer shielding layer 7 and protective sleeve 10, described reinforcement 1 is to intersect at described belting layer 3 centers by three insulation boards, described belting layer 3 is divided into three panes, described coaxial core 2 is wrapped in the pane inside of described reinforcement 1, described coaxial core 2 circumference respectively with belting layer 3, described reinforcement 1 is tangent, between described internal shield 4 and described outer shielding layer 7, be provided with insulating barrier 6, three copper wire drainage threads 8 of described insulating barrier 6 internal package, a ground connection core 5, coated metal layer 9 between described outer shielding layer 7 and described protective sleeve 10.

Described coaxial core 2 is three groups, and described coaxial core 2 is made up of the outer conductor of the outer aluminium foil braiding of cobalt plating fine copper inner wire, skinning cortex and steel wire.

Described metal level 9 is to mould by the zinc-plated anaerobic steel wire of 98.40% annealing outsourcing fluorine the polyurethane that described protective sleeve material is organic silicon ribbon of containing mica, graphite, antioxidant.

Described protective sleeve 10 materials are the polyurethane of organic silicon ribbon of containing mica, graphite, antioxidant.

The permission reversed bending of this cable 7,000,000 times; The shielding rejection coefficient of this cable is less than 0.6.

The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
