Background technology
The ordinary copper twisted wire is usually used in common electric machine, electrical equipment, instrument, transformer etc., but is not suitable for the occasion of high frequencies such as high-tech computer monitor, colored picture tube deflecting coil, high-frequency inductor high frequency coil, telecommunications winding, high-speed induction motor, high frequency transformer, sound equipment line, microwave oven, electromagnetic disc.When existing common enamel-cover twisted wire uses simultaneously to need some single lines when turning out a produce, not through stranded, arrangement unordered and uneven eddy current that produces of pitch and kelvin effect, the phenomenon of Zeng Daing simultaneously, cause the output impedance instability, transmission characteristic is bad, the image frame distortion, and common enamel-cover copper stranded conductor is when being used for motor, also need dipping lacquer bonding, manufacturing process complexity not only, and easily cause environmental pollution.
The utility model content
Technical problem to be solved in the utility model is, a kind of sharp thatch enamelled wire of tack polyester-imide that can be used in high frequency occasions such as computer monitor, colored picture tube deflecting coil, telecommunications winding and high-speed induction motor in the high-tech area, transformer is provided, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model: the compound sharp thatch enamelled wire of a kind of polyester-imide/polyamidoimide.This profit thatch enamelled wire is by at least two stranded forming of enamelling cuprum round line, is coated with first insulating barrier and second insulating barrier in the conductive line surfaces of every enamelling cuprum round line; First insulating barrier is the polyester imine resin lacquer, and second insulating barrier is the polyamide-imide resin lacquer; First insulating barrier is coated on conductive line surfaces, and second insulating barrier is coated in first surface of insulating layer.
In the compound sharp thatch enamelled wire of above-mentioned polyester-imide/polyamidoimide, enamelling cuprum round line is disposable disc molding and the strands of being twisted into.
The beneficial effects of the utility model: compared with prior art, sharp thatch enamelled wire of the present utility model is formed through high accuracy is stranded by many enamelling cuprum round line, every enamelling cuprum round line has two insulating barriers, first insulating barrier is the polyester imine resin lacquer, have superior heat resistance, high strength and good insulation property, have 220 grades of high thermal endurance classs and high thermal shock resistance properties, and employing paint film multiple tracks painting process, make its folding, heat-resisting, anti-wear performance is good, high strength, paint film is difficult for breaking, and film integrity is good.Second insulating barrier is the polyamide-imide resin lacquer, has characteristic wear-resisting, anti-corona.Sharp thatch enamelled wire of the present utility model adopts the novel strand system technology of disposal molding one-tenth dish, realize the disposable disc molding that is twisted into, and strands, making that its surface area is big, Distribution of Magnetic Field is even, kelvin effect is little, transmission characteristic is good, the high frequency equivalent resistance is low, eddy current is little, temperature rise is low, image frame is undistorted, has good impedance behavior, and transmission characteristic is good, anti-corona ability is strong, and the high frequency voltage bearing capacity is strong.The utlity model has good flexibility, folding resistance, proof voltage, film integrity and hyperthermia impact properties, paint film is difficult for breaking, and Distribution of Magnetic Field is even, kelvin effect is little, transmission characteristic is good, lubrification is good, the high frequency voltage bearing capacity is strong, also have characteristics such as lubricated, wear-resisting, be convenient to the coiling of coil windings, can be applicable to color monitor (pipe) deflecting coil, also can be widely used in various high-frequency timing, special machines, national defense industry, electrical equipment winding such as heat-resisting, cold-resistant, need not dipping lacquer bonding, simplified manufacturing technique, and do not have the dipping lacquer environmental pollution.
Description of drawings
Fig. 1 is a sharp thatch enamelled wire perspective view of the present utility model;
Fig. 2 is the cross-sectional structure schematic diagram of single enamelling cuprum round line.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Embodiment.As shown in Figure 1 and Figure 2, form through high accuracy is stranded, be coated with first insulating barrier 3 and second insulating barrier 4 on lead 2 surfaces of every enamelling cuprum round line 1 by multiply enamelling cuprum round line 1; First insulating barrier 3 is the polyester imine resin lacquer, second insulating barrier 4 is the polyamide-imide resin lacquer, good insulation preformance, heat-resisting, cold tolerance is good, mechanical strength is high and have the favorable chemical resistance energy, its temperature resistant grade height, good with the copper associativity, every performance meets the requirements.First insulating barrier 3 is coated on lead 2 surfaces, and second insulating barrier 4 is coated in first insulating barrier, 3 surfaces.Enamelling cuprum round line 1 adopts felt mold painting production process, realizes two disposable japannings of insulating barrier, and adopts disposable strand system to be molded into the novel strand system technology of dish and special-purpose disposable disc molding and the strands of being twisted into of wringing equipment realization.
Execution mode of the present utility model is not limited to the foregoing description, all belongs within the protection range of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
