Description
Technical field
The utility model relates to a kind of cable machinery, is specially a kind of high-low temperature resistant fire resistant flame retardant computer cable, belongs to computer field of cables.
Background technology
Cable normally forms by several or several groups of wires are stranded around center, the similar rope of its shape, simultaneously outerly covers high-strength insulating layer.The manufacture of cable is generally from conductor processing, adds that insulation, shielding etc. are made layer by layer in the periphery of conductor.The structure of common product is more complicated, and the level of superposition is more.In computer realm, cable needs very strong toughness, and the cable do not processed in use easily makes core fracture, and general cable does not have the characteristic of tension and high-low temperature resistant and fire resistant flame retardant.
Summary of the invention
The purpose of this utility model is just to provide a kind of high-low temperature resistant fire resistant flame retardant computer cable to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of high-low temperature resistant fire resistant flame retardant computer cable, comprise oversheath, steel screen layer, screen, plastic foam layer, tensile steel wire, conductor and packed layer, it is characterized in that: described oversheath is positioned at outermost layer, described steel screen layer is positioned at the inside of oversheath and the periphery of steel screen layer contacts with oversheath, described screen is positioned at the inside of steel screen layer and contacts with the inner headed face of steel screen layer, described plastic foam layer contacts with screen and is wrapped in packed layer, described conductor is positioned at the penetralia of device and is filled layer and is wrapped in, in described conductor, core is at least provided with three, also tensile steel wire is enclosed with in the inside of packed layer.
Preferably, the outside of described oversheath is with concavo-convex particle.
Preferably, the steel wire of described steel screen layer has extremely strong elasticity.
Preferably, the core in described conductor adopts high-quality oxygen-free copper to be entwined.
Preferably, described tensile steel wire has stronger toughness.
The beneficial effects of the utility model are: this temperature fire resistant flame retardant computer cable of resistance to high end is reasonable in design, the outside of oversheath is with concavo-convex particle, concavo-convex particle the contact area that can reduce cable and ground is set, prevent the damage rubbed to cable, the steel wire of steel screen layer has extremely strong elasticity, extremely strong elasticity can make cable not easily be fractureed, and tensile steel wire has stronger toughness, under the synergy of tensile steel wire and steel screen layer, strengthen the resistant to damage performance of cable greatly.
Accompanying drawing explanation
Fig. 1 is structural representation described in the utility model;
In figure: 1, oversheath, 2, steel screen layer, 3, screen, 4, plastic foam layer, 5, tensile steel wire, 6, conductor and 7, packed layer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of high-low temperature resistant fire resistant flame retardant computer cable, comprise oversheath 1, steel screen layer 2, screen 3, plastic foam layer 4, tensile steel wire 5, conductor 6 and packed layer 7, described oversheath 1 is positioned at outermost layer, the surface of described oversheath 1 is provided with concavo-convex particle, concavo-convex particle the contact area that can reduce cable and ground is set, slow down the rate of wear of cable, prevent the damage rubbed to cable, effectively protect cable, and oversheath 1 has carried out special processing, has good fire resistant flame retardant, makes cable not easily be burned; Described steel screen layer 2 is positioned at the inside of oversheath 1 and the periphery of steel screen layer 2 contacts with oversheath 1, and the steel wire of described steel screen layer 2 has extremely strong elasticity, and extremely strong elasticity can make cable not easily be fractureed, and prevents cable from damaging under repeatedly bending; Described screen 3 is positioned at the inside of steel screen layer 2 and contacts with the inner headed face of steel screen layer 2, described plastic foam layer 4 contacts with screen 3 and is wrapped in packed layer 7, described plastic foam layer 4 has the effect of fabulous heat-insulation and heat-preservation, makes cable have the characteristic of extremely strong high-low temperature resistant; Described conductor 6 is positioned at the penetralia of device and is filled layer 7 and is wrapped in, in described conductor 6, core is at least provided with three, tensile steel wire 5 is also enclosed with in the inside of packed layer 7, described tensile steel wire 5 has stronger toughness, at tensile steel wire 5 with under the synergy of steel screen layer 2, strengthen the resistant to damage performance of cable greatly, add the useful life of cable.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
