Abstract
The utility model discloses an ultrathin polyimide enameled flat copper wire with an oblate rectangular cross section, comprising an internal conductor and an insulating layer composited on the surface of the internal conductor, wherein the insulating layer is a polyimide paint layer, the conductor is an ultrathin flat conductor with a large width-thickness ratio, the ratio of length to width of the oblate rectangle is larger than 5, and the short side of the flat rectangle is arc or an arc with a straight line. The ultrathin polyimide enameled flat copper wire can satisfy the demands of an airplane generator for a -60 DEG C to 300 DEG C broad width enameled wire, has the ultrathin polyimide enameled layer with a large width-thickness ratio, and can be used for airplanes, submarine warships, oil mines, coal mines, generators and motors of automobiles, etc.
Description
Technical field
The utility model relates to a kind of ultra-thin polyimides enamel-cover flat type copper wire.
Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and paint film insulating barrier two parts, and bare wire forms through repeatedly painting, curing behind annealing softening again.But producing is the conformance with standard requirement, satisfies the product of customer requirement again and is not easy, and it receives raw material quality; Technological parameter, production equipment, factor affecting such as environment; Therefore, the mass property of various enamelled wires has nothing in common with each other, but all possesses mechanical performance; Chemical property, electrical insulation properties, hot property four big performances.
The classification of enamelled wire has by the insulating material branch: acetal paint envelope curve, polyester enamelled wire, polyurethane enamelled wire, modified poly ester enamelled wire, polyester-imide enamelled wire, polyester-imide/polyamide acid imide enamelled wire, polyimide enameled wire or the like.
Purposes by enamelled wire can be divided:
1, general purpose enamelled wire (ordinary lines) is mainly used in general motor, electrical equipment, instrument.The winding wire of workplaces such as transformer, as: polyester enamelled wire, modified poly ester enamelled wire.
2, heat-resistant enamelled wire; Be mainly used in the motor of 180 ℃ and above temperature environment work, electrical equipment, instrument, the winding wire of workplaces such as transformer, as: polyester-imide enamelled wire, polyimide enameled wire, polyester-imide/polyamidoimide composite enameled wire etc.
3, the enamelled wire of special purpose; Be meant to have the enamelled wire that certain mass property requires, be used for the winding wire of specific occasions, as: polyurethane enamelled wire (directly weldering property), self-binding enamel wire etc.
Press the conductor material branch: copper cash, aluminum steel, alloy wire.
Press the material shape branch: circle line, lenticular wire, tubular wire.
Press the insulation thickness branch: thin paint film line, paste paint film line and thickening paint film line.
Because aircraft generator need use under-60 ℃～300 ℃ states with enamelled wire; Require enamelled wire to have the wide cut heat resistance; The insulating barrier of enamelled wire must guarantee that also electric property, mechanical performance etc. meet the demands under this condition, and existing product is difficult to satisfy.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of ultra-thin polyimides enamel-cover flat type copper wire is provided, and the requirement of it has satisfied aircraft generator right-60 ℃～300 ℃ wide cut temperature resisting paint envelope curves has big flakiness ratio, ultra-thin, polyimide varnish covering; Can be applied to aircraft; The submarine warship, oil, coal etc. are mining, the generator of electric automobile etc. and motor.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of ultra-thin polyimides enamel-cover flat type copper wire; Said ultra-thin polyimides enamel-cover flat type copper wire cross section is that a prolate is square; Comprise inner conductor and the insulating barrier that is compound in the inner conductor outer surface; Said insulating barrier is a polyimide varnish, and said conductor is big flakiness ratio, ultra-thin flat conductor.
The thickness of said insulating barrier is less than 0.12mm; Length that said prolate is square and wide ratio are greater than 5.
The square minor face of prolate is an arc.
The requirement of the utility model has satisfied aircraft generator right-60 ℃～300 ℃ wide cut temperature resisting paint envelope curves; Have big flakiness ratio, ultra-thin, polyimide varnish covering, can be applied to aircraft, the submarine warship; Oil, coal etc. are mining, the generator of electric automobile etc. and motor.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1; The utility model provides a kind of ultra-thin polyimides enamel-cover flat type copper wire; Said ultra-thin polyimides enamel-cover flat type copper wire cross section is that a prolate is square; Comprise inner conductor 1 and the insulating barrier 2 that is compound in the inner conductor outer surface, said insulating barrier is the polyimides enamelled coating, and said insulating barrier is a thin dielectric layer.
The thickness of said insulating barrier is less than 0.12mm; Length that said prolate is square and wide ratio are greater than 5.
The square minor face of prolate is an arc.
The requirement of the utility model has satisfied aircraft generator right-60 ℃～300 ℃ wide cut temperature resisting paint envelope curves; Have aspect ratio, ultra-thin, polyimide varnish covering, can be applied to aircraft, the submarine warship; Oil, coal etc. are mining, the generator of electric automobile etc. and motor.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to execution mode.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being amplified out thus or change still are among the protection range of the utility model.
