Description

A kind of high-temperature resistant electronic wire

Technical field

The utility model is related to technical field of motors, specially a kind of high-temperature resistant electronic wire.

Background technology

Electric wire is electric equipment, the wire of each energization unit of electronic instrument inside connection, and electric wire is generally with logical light current Based on, there is the characteristic of bigger difference with the cable of forceful electric power category.Existing electric wire is typically by conductor wire core and insulating bag Covering layer is constituted, wherein, conductor wire core is constituted using single beam or multi beam copper wire, and insulating barrier is made of rubber layer.

As electrical equipment, electronic product develop towards microminiaturization, requirement to electric wire also more and more higher, particularly in resistance to height There is higher and higher require in terms of temperature, wearability, flexibility；Existing electric wire resistance to elevated temperatures is bad, typically at 80 DEG C Its insulating barrier of left and right occurs as soon as softening, or even is burned.

Utility model content

The purpose of this utility model is to provide a kind of high-temperature resistant electronic wire, with asking for solving to propose in above-mentioned background technology Topic.

To achieve the above object, the utility model provides following technical scheme：A kind of high-temperature resistant electronic wire, including cored wire Fluorocarbon polymer nanometer layer, the fluorocarbon polymer are set on the outside of cladding flame retardant coating, the flame retardant coating on the outside of layer, the core-wire layer Cladding polyester film band, the polyester film on the outside of fiberglass braided layer, the fiberglass braided layer are set on the outside of nanometer layer Cladding restrictive coating on the outside of butyronitrile insulating barrier, the butyronitrile insulating barrier is set on the outside of band.

It is preferred that, the flame retardant coating includes solid composite, phenolic coating and liquid adhesive, and the liquid is bonded Agent is arranged on the lower section of solid composite, and the phenolic coating is coated in above the solid composite, the solid group Compound includes inorganic light weight fiber layer, organic light fibre layer and fire clay layer, the inorganic light weight fiber layer, organic lightweight Fibrous layer and fire clay layer close-packed arrays successively.

It is preferred that, the restrictive coating uses the outer jacket that low-smoke halogen-free polyolefin flame-proof material is made.

It is preferred that, the thickness of the fluorocarbon polymer nanometer layer is 300-600nm.

Compared with prior art, the beneficial effects of the utility model are：

（1）The utility model novel in structural design, can substantially increase the resistance to elevated temperatures of electric wire, it is ensured that electric wire Service life.

（2）The flame retardant coating good toughness that the utility model is used, with insulation and fireproof advantage, can extend electronics The overall service life of line.
