Abstract
The utility model provides an ultrathin 240-level modified polyimide enamel-cover copper flat wire, which can overcome the shortcomings of low space utilization factor and small specific surface of an ordinary polyimide enamel-cover copper round wire, and simultaneously effectively solves the problem that the polyimide paint is not suitable for the transportation and storage at normal temperature in production enterprises so as to be suitable for the production of the enamel-cover copper flat wire. The flat wire comprises a copper conductor, wherein the periphery of the copper conductor is coated with a polyimide lacquer layer. The utility model is characterized in that the copper conductor has a rectangular cross section, the size of the wide edge of the cross section of the copper conductor is 1.2mm-14mm, and the size of the narrow edge is 0.2mm-1.00mm.
Description
Technical field
The utility model relates to the enamelled wire technical field, is specially a kind of ultrathin 240-grade modified polyesterimide enameled rectangular copper wire.
Background technology
The polyimides enamel covered wire is the highest enamelled wire of temperature resistant grade up to now, and it has favorable mechanical performance and thermal stability, and it mainly uses the place that Aeronautics and Astronautics, nuclear power, extraordinary electric tool etc. have specific (special) requirements.Present polyimide enameled wire mostly is enamel-cover circle line, its copper conductor cross section is circular, copper conductor 1 periphery is coated with polyimide varnish 2(and sees Fig. 1), its good mechanical property, thermal stability are excellent, but its diameter generally is not more than 2.00mm, has the shortcoming that space utilization factor is low, specific area is little; And the polyimide varnish storage condition requires harsh, must store at low temperatures, so it is unfavorable for transportation and storage under manufacturing enterprise's normal temperature.
Summary of the invention
At the problems referred to above, the utility model provides a kind of ultrathin 240-grade modified polyesterimide enameled rectangular copper wire, it can overcome the shortcoming that common polyimide varnish copper-clad circle space of lines usage factor is low, specific area is little, it effectively solves common polyimide varnish and is not suitable for transportation and the problem that stores under manufacturing enterprise's normal temperature simultaneously, makes it can adapt to enameling copper strap wire production.
Its technical scheme is such, it comprises copper conductor, described copper conductor periphery is coated with the polyimides enamelled coating, it is characterized in that: described copper conductor is the rectangle cross section, and described copper conductor cross section broadside is of a size of 1.2mm～14mm, narrow limit is of a size of 0.2mm～1.00mm.
It is further characterized in that: described polyimides enamelled coating is the modified polyimide enamelled coating.
Ultrathin 240-grade modified polyesterimide enameled rectangular copper wire of the present utility model, it adopts ultra-thin copper flat conductor, under the situation of same conductor sectional area, it can effectively increase the conductor specific area, improve heat dispersion, its volume is little simultaneously, can effectively improve space availability ratio; The externally coated modified polyimide lacquer of its copper conductor is compared with common polyimide varnish, and thermal stability is strong, can store at normal temperatures and transport, and more adapts to the coating of lenticular wire.
