Abstract
The invention discloses a three-core pair twisting control cable for a computer. The three-core pair twisting control cable comprises two sets of main cable cores, two sets of control cable cores, a semiconductive belting layer, a shielding layer and a protective cover. The main cable cores are formed by twisting three insulating cable cores in a paired mode. The main cable cores and the control cable cores are arranged in an adjacent mode. The semiconductive belting layer is internally provided with a grounding cable core. A waterproof layer is arranged between the shielding layer and the protective cover. The cable is good in conductivity, high-temperature resistant, dragging and dropping resistant, bending resistant, good in shielding effect, oil proof, waterproof, low in smoke emission, free of halogen, environmentally friendly and low in damage to the human body and the surroundings, and is applied to a computer system.
Description
Technical field
The invention belongs to field of cables, relate in particular to three core pair-twisted control cables for a kind of computer.
Background technology
At present, along with the growth of cable consumption, the quality requirement of cable is also constantly improved.The cable using in the fields such as computer, high temperature resistant to cable, waterproof oil resistant, anti-ly pulls acid and alkali-resistance, and requirement corrosion-resistant and anti-interference aspect is all high especially.Such as, the permeability of the restrictive coating that common igelite is made is stronger, easily makes moist, and causes inner oxidation, affects normal signal transmission, has shortened the useful life of whole cable.And for example general cable exists cable fire and will burning can produce a large amount of dense smoke, hydracid corrosive gas, makes rescue work be difficult to carry out, the problems such as life threatening.Only meet the requirements, could improve in these fields the fail safe while manufacturing.
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 possess conduct electricity very well, waterproof oil resistant, anti-interference, low smoke and zero halogen environmental protection, high temperature resistant, the anti-three core pair-twisted control cable control cables for computer that pull the advantages such as endurance.
The present invention takes following technical scheme to realize: three core pair-twisted control cables for a kind of computer, it comprises master core, control core, semiconductive belting layer, screen and protective sleeve, described master core, described control core is two groups, described master core is to be formed by three insulated wire cores pair twists, described insulated wire cores is by nickel-clad copper inner wire, the outer conductor of fluorubber skinning cortex and the outer aluminium foil braiding of annealing anaerobic steel wire forms, described master core and adjacent the arranging of described control core, described semiconductive belting layer inside is also provided with a ground connection core, between described screen and described protective sleeve, be provided with watertight composition.
The core that described control core consists of the ultra-fine soft copper tow strand of anaerobic annealing nickel plating and nickel coated steel wire mesh grid, second the third lapping layer being wrapped in outside core form.
Described watertight composition is closely arranged and is formed by the water blocking tape of a plurality of interpolation graphite, carbon dust, waterproof.
Described protective sleeve is to consist of the low-smoke halogen-free polyolefin material that adds organic silicon ribbon, ceramic fibre.
Described ground connection core is that the annealed copper aluminum-alloy wire outsourcing annealed wire stranded braiding to the right by electroplate forms, and described earth connection core diameter is 0.55 millimeter.
The present invention has following beneficial effect in sum: this cable conduction performance is good, high temperature resistant, anti-pulling, resistance to bending, is mainly used in the cable that computer system is used, and shield effectiveness is good, significantly improve the anti-electromagnetic interference capability of computer cable, oil resistant waterproof also possesses low smoke and zero halogen environmental protection simultaneously, to human body and surrounding environment, damages less.

As shown in Figure 1, the present invention takes following technical scheme to realize: three core pair-twisted control cables for a kind of computer, it comprises master core 1, control core 2, semiconductive belting layer 3, screen 4 and protective sleeve 6, described master core 1, described control core 2 is two groups, described master core 1 is to be formed by three insulated wire cores pair twists, described insulated wire cores is by nickel-clad copper inner wire, the outer conductor of fluorubber skinning cortex and the outer aluminium foil braiding of annealing anaerobic steel wire forms, described master core 1 and adjacent the arranging of described control core 2, described semiconductive belting layer 3 inside are also provided with a ground connection core 7, between described screen 4 and described protective sleeve 6, be provided with watertight composition 5.
The core that described control core 2 consists of the ultra-fine soft copper tow strand of anaerobic annealing nickel plating and nickel coated steel wire mesh grid, second the third lapping layer being wrapped in outside core form.
Described watertight composition 5 is closely arranged and is formed by the water blocking tape of a plurality of interpolation graphite, carbon dust, waterproof.
Described protective sleeve 6 is to consist of the low-smoke halogen-free polyolefin material that adds organic silicon ribbon, ceramic fibre, has stronger resistance to elevated temperatures.
Described ground connection core 7 is that the annealed copper aluminum-alloy wire outsourcing annealed wire stranded braiding to the right by electroplate forms, and described earth connection core diameter is 0.55 millimeter.
This cable allows reversed bending 6,000,000 times; It is 105 ℃ that this cable allows operational environment maximum temperature; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
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.
