Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of cable with quick heat radiating performance.
Background technology
Cable is used for transmitting the electric charge of directed movement, has a wide range of applications in fields such as electric power system, the information transmission system and instrument systems.In transmission charge process, because the wire in cable has certain resistance, certain heat can be produced when the current flows, if heat can not be discharged for a long time, then the resistance of conductor can be made to increase on the one hand, produce more heats, the plastic casing aging speed playing insulating effect in cable can be made on the other hand to accelerate, have a strong impact on the useful life of cable.In addition, in a lot of construction environment, such as the complexity such as underground, seabed lays environment, requires that cable has higher anti-pressure ability, if cable compression strength is too low, then more easily causes and damages or fracture.
Summary of the invention
A kind of cable with quick heat radiating performance that the present invention proposes, comprising: many conductors, heat-conducting layer, heat radiation sheath and oversheaths;
Conductor periphery is coated with the first insulating barrier, screen and the second insulating barrier successively and forms core; Many cores are twisted into cable core; Heat-conducting layer is coated on cable core periphery, and its circumference perpendicular to the cross section of length direction is wavy shaped configuration; Thermal conductive silicon glue-line is filled with between heat-conducting layer and cable core;
Heat radiation sheath be coated on heat-conducting layer periphery, heat radiation sheath on along its length and circumferencial direction be provided with multiple through hole; Oversheath is coated on heat radiation sheath periphery; Heat radiation sheath adopts elastic rubber material to make, and oversheath adopts heat sink material to make.
Preferably, the second insulating barrier is provided with the different mark corresponding to conductor.
Preferably, screen is metal wire shielding layer.
Preferably, multiple through hole forms the belt passing round being wrapped in heat radiation sheath periphery.
Preferably, through hole is spherical pore, and its diameter equals the thickness of heat radiation sheath.
Preferably, oversheath adopts heat-conducting silicon rubber to make.
In the present invention, the heat that cable core produces outwards is dispelled the heat by thermal conductive silicon glue-line and heat-conducting layer, and heat-conducting layer surface adopts wavy shaped configuration, adds heat-conducting area, is conducive to distributing of cable core heat.The heat of heat-conducting layer is outwards distributed by the through hole on heat radiation sheath.The setting of heat radiation sheath and through hole, both can be the elastic deformation space that cable provides enough, ensured the ability of anti-deformation of cable, turn avoid the problem of heat-conducting layer thermal reservoir.
Accompanying drawing explanation
Fig. 1 is a kind of construction of cable schematic diagram with quick heat radiating performance that the present invention proposes.
Embodiment
With reference to Fig. 1, a kind of cable with quick heat radiating performance that the present invention proposes, comprising: many conductors 1, heat-conducting layer 2, heat radiation sheath 3 and oversheaths 4.
Conductor 1 periphery is coated with the first insulating barrier 11, screen 12 and the second insulating barrier 13 successively and forms core.In present embodiment, screen 12 is metal wire shielding layer, and it can prevent the signal that conductor 1 transmits from leaking.
Many cores are twisted into cable core.The signal cross-talk that screen 12 coordinates the first insulating barrier 11 and the second insulating barrier 13 can avoid between different core.In present embodiment, the second insulating barrier 13 is provided with the different mark corresponding to conductor 1, and such as, the color of the second insulating barrier 13 is different, to identify core.
Heat-conducting layer 2 is coated on cable core periphery, and its circumference perpendicular to the cross section of length direction is wavy shaped configuration, so can increase heat-conducting layer 2 heat-conducting area, increases.Be filled with thermal conductive silicon glue-line 5 between heat-conducting layer 2 and cable core, both ensure that the turgor of cable, further increase again the efficiency of the heat derivation that cable core produces.
Heat radiation sheath 3 be coated on heat-conducting layer 2 periphery, heat radiation sheath 3 on along its length and circumferencial direction be provided with multiple through hole 30.Multiple through hole 30 forms the belt passing round being wrapped in heat radiation sheath 3 periphery, the efficiency of distributing to Exterior cable with the heat improving heat-conducting layer 2.In present embodiment; through hole 30 is spherical pore; its diameter equals the thickness of heat radiation sheath 3; so; both ensure that the aperture of through hole 30 was to improve radiating efficiency; turn avoid through hole 30 and be positioned at that the opening of heat radiation sheath 3 surfaces externally and internally is excessive reduces heat radiation sheath 3 sealing, do not reach the protection object to cable core.
Oversheath 4 is coated on heat radiation sheath 3 periphery, avoids through hole 30 to be exposed in air, causes the pollutions such as extraneous dust.
In present embodiment, heat radiation sheath 3 adopts elastic rubber material to make, to increase cable ability of anti-deformation.Oversheath 4 adopts heat sink material to make, so that distributing of cable internal heat, specifically can select heat-conducting silicon rubber.
In present embodiment, the thickness of oversheath 4 and density are less than thickness and the density of heat radiation sheath 3, so, heat radiation sheath 3 can be the elastic deformation space that cable provides enough, and oversheath 4 adopts less thickness and density, both having avoided heat radiation sheath 3 is exposed in air, and the hot-air that turn avoid savings in through hole 30 cannot distribute.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
