Abstract
The utility model discloses a high temperature resisting and fire resisting cable for an automobile. The cable comprises a single conductor with a sectional area of 0.5 square centimeter to 2.5 square centimeters. The conductor is wrapped by a fire resisting layer which is extruded by an insulating layer. A tinned copper wire braided shielding layer is braided outside the insulating layer. The outermost layer of the cable is extruded by a polyolefin outer sheath. The insulating layer is formed by extruding fluorine plastic at an outer layer of the fire resisting layer. The cable of the utility model has the performance indexes of light weight, heat resistance, inflaming retarding, fire resistance and the like, and problems of a large size, a small load flow and the like are solved.
Description
Technical field:
The utility model relates to the high temperature resistant fire-resisting cable of a kind of automobile.
Background technology:
Cable for car is to connect each systems such as auto electric, fire control, manipulation, for each parts of automobile provide electrical source of power, control signal and data message.Be subjected to the restriction in automobile fuselage space, the cable system wiring generally all concentrates in narrow and small engine, so the little external diameter of automobile cable system requirements, high integrated, high light; Because wire is of a great variety, all kinds of power lines, low-and high-frequency holding wire, data wire are mixed in together, and electric circumstance is very complicated, thereby its incipient fault is increased, many vehicle failure are all directly or indirectly relevant with the cable system fault, and therefore, the cable security problem is particularly important.The reducing of engine room space makes the temperature of this part of vehicle increase, and the continuous high temperature of 150 ° of C is often arranged.And the increase of electronic equipment and engine room size dwindle that conductor cross-section is little, the thin and resistant to elevated temperatures cable of insulating barrier with regard to requiring to use, also require these cables soft as far as possible put in place so that a wire harness that bands together is laid in automobile.These problems are all the challenges to cable industry.How traditional cable for car solves heatproof in actual working environment, oil resistant, the feature of environmental protection, the external diameter problem is a technical barrier always greatly.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of automobile high temperature resistant fire-resisting cable, has the performance index such as light-duty, heat-resisting, fire-retardant, fire-resistant, and this cable has also solved the problems such as volume is large, ampacity is little.
The utility model technical solution problem adopts following technical scheme:
The high temperature resistant fire-resisting cable of a kind of automobile comprises single conductor, and described cross-sectional area of conductor is long-pending is 0.5-2.5mm
2Be surrounded with flame retardant coating at described conductor skin, insulating barrier extrudes outside described flame retardant coating, is woven with the tinned copper wire woven shield outside described insulating barrier, the outermost layer of cable is extruded with the polyolefin oversheath, and described insulating barrier adopts fluoroplastics to extrude in the outer formation of described flame retardant coating.
Described flame retardant coating adopts two-sided compound white clouds master tape wrapped.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
