Description
Technical field：
The utility model is related to a kind of mouse bite preventing high temperature resistant computer cables.
Background technology：
Traditional high-temp.-resistant electric cable for computer directly coats exotic material or filling exotic material, this height using conductor
Warm computer cable can not allow the cable to possess high heat-resisting performance, when computer cable runs into the heat that its conductor thread core is distributed
When being accumulated at cable core, exotic material can be shunk and come off, and production work personnel health can also be damaged by not only polluting the environment.It is resistance to
Computer cable normal work is just most likely resulted in after high-temperature material heat shrinkable, service life reduction improves circuit dimension
Protect cost.In addition, in actual use, computer cables are easily bad by damaged by rats, the lighter's power-off, severe one triggers fire.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of good heat dissipation effect, and energy high temperature resistant mouse bite preventing is bad
Mouse bite preventing high temperature resistant computer cables.
Technical solution of the present utility model is to provide a kind of mouse bite preventing high temperature resistant computer cables, by three wires,
Core body is supported to constitute cable core, wire includes the conductor and the polyvinyl chloride insulation layer being coated on the outside of conductor, support positioned at middle part
Core body is that circumferentially mode is integrally formed three metal fan rings, and the opening of three metal fan rings is outwardly and two gold of arbitrary neighborhood
Angle between category fan ring upper shed is 120 degree；The outer coaxial sleeve of cable core is provided with instlated tubular, and instlated tubular is provided with the row being outwards vented
Tracheae, the cross section of instlated tubular is regular polygon, and two sides of instlated tubular arbitrary neighborhood are provided with fillet, and blast pipe is arranged on instlated tubular
Each fillet on；Coated successively outside instlated tubular outside fire-resistant isinglass belt lapping layer and fluororesin restrictive coating, fluororesin restrictive coating also
Spiral armouring stainless steel band steel pipe is arranged, blast pipe outwards passes fire-resistant isinglass belt lapping layer and fluororesin oversheath from instlated tubular
Layer.
Using compared with prior art, the utility model has advantages below after above structure：Three wire difference are longitudinal
In three metal fan rings and against the inner circumferential of metal fan ring, in said structure arrangement, on the one hand, the shape inside cable core
Into high-efficiency heat conduction path, make cable core interior environment temperature balanced, on the other hand, the uniform electromagnetic field distribution produced in cable core, phase
Mutually disturb small, Electro Magnetic Compatibility is good, and instlated tubular discharges hot gas by the blast pipe being disposed thereon, by by cable core
The heat distributed outwards transmit, greatly improve the resistance to elevated temperatures of computer cable, reduction computer cable insulation ag(e)ing
Spiral armouring stainless steel band steel pipe is also arranged outside risk, fluororesin restrictive coating, can effectively prevent bad by damaged by rats.
Preferably, the center of the support core body is provided with one or more longitudinal holes.Improve heat dispersion.
Preferably, the cross section of the instlated tubular is square, instlated tubular is elastic tube.
Further, also fill up aramid fiber composite material between instlated tubular and fire-resistant isinglass belt lapping layer, make instlated tubular each
Side offsets with cable core.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in figure 1, a kind of mouse bite preventing high temperature resistant computer cables, constitute cable core by three wires 1, support core body 2, lead
Line 1 includes the conductor and the polyvinyl chloride insulation layer being coated on the outside of conductor positioned at middle part, and support core body 2 is three metal fan rings
Circumferentially mode is integrally formed, and the opening of three metal fan rings is outwardly and between two metal fan ring upper sheds of arbitrary neighborhood
Angle is 120 degree, and support core body 2 is made by aluminum alloy materials.Because aluminium alloy supports the lightweight intensity of core body big, increase
The strong mechanical performance of cable, meanwhile, the center of the support core body 2 is provided with one or more longitudinal holes 3, convenient radiating；
The outer coaxial sleeve of cable core is provided with instlated tubular 4, and instlated tubular 4 is provided with the blast pipe 5 being outwards vented, and the cross section of instlated tubular is positive four side
Shape, 4 arbitrary neighborhood of instlated tubular, two sides are provided with fillet, and blast pipe 5 is arranged on each fillet of instlated tubular；Instlated tubular 4 it is outer according to
Secondary cladding fire-resistant isinglass belt lapping layer 6 and fluororesin restrictive coating 7, fluororesin restrictive coating outer 7 are also arranged spiral armouring stainless steel band
Steel pipe 8, blast pipe 5 outwards passes fire-resistant isinglass belt lapping layer 6 and fluororesin external sheath layer 7 from instlated tubular, and such blast pipe dissipates
The heat gone out can be discharged by spiral armouring stainless steel band steel pipe.Further, instlated tubular 4 and fire-resistant isinglass belt lapping layer 6
Between also fill up aramid fiber composite material, each side of instlated tubular is offseted with cable core.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.Equivalent structure or equivalent flow conversion that every utilization the utility model specification and accompanying drawing content are done, are included in this
Within the scope of patent protection of utility model.
