Abstract
Disclosed in the utility model is a 155-level direct-welding polyurethane/polyamide composite litz wire that is formed by twisting of at least two enameled single wires. Two insulating layers coat the surface of a round copper wire (2) of each of the enameled single wires; the first insulating layer (3) is a direct-welding polyurethane painting layer coating the surface of the round copper wire (2); and the second insulating layer (4) is a polyamide insulation painting layer coating the surface of the first insulating layer (3). According to the utility model, two insulating painting layers including the direct-welding polyurethane painting layer and the polyamide insulation painting layer coat each of the enameled single wires, so that the enameled single wires have insulating performances; and at least two enameled single wires are twisted to form the composite litz wire. Therefore, the generated eddy current and skin effect are normal; and the output impedance is stable. The litz wire has the high heat-resistant level, wherein the thermal level is 155; and the provided litz wire is suitable for an energy saving lamp and an LED lamp electronic transformer and the like.
Description
Technical field
The utility model relates to a kind of copper-clad twisted wire, particularly a kind of 155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide.
Background technology
The compound enamelling cuprum round line of straight weldering based polyurethane/polyamide is applicable to electric tool, high frequency transformer occasion, because electricity-saving lamp, LED lamp need voltage stabilizing, current stabilization, especially to when producing powerful electricity-saving lamp product, needing some single lines to use simultaneously, do not pass through stranded, arrange the phenomenon that eddy current that unordered and pitch inequality produces and kelvin effect increase simultaneously, cause the output impedance instability.
The utility model content
The purpose of this utility model is, a kind of 155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide are provided.The utlity model has the stable and result of use of output impedance characteristics preferably.
The technical solution of the utility model: 155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide, it is characterized in that: by at least two stranded forming of enamel-cover single line, the copper round wire surface of every enamel-cover single line is coated with dielectric layers, wherein first insulating barrier is straight weldering based polyurethane lacquer, be coated on the copper round wire surface, second insulating barrier is polyamide insulating varnish, is coated on the surface of first insulating barrier.
In aforesaid 155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide, described enamel-cover single line is disposable disc molding and the strands of being twisted into.
In aforesaid 155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide, described first insulating barrier and second insulating barrier are molten to be one.
Compared with prior art, the utility model passes through at enamel-cover single line applied in two coats insulating varnish, make the enamel-cover single line have insulating properties, form by at least 2 enamel-cover single lines are stranded again, therefore make the eddy current and the kelvin effect that produce normal, output impedance is stable, has high thermal endurance class simultaneously, thermal level is 155 grades, is applicable to electricity-saving lamp, LED lamp electronic transformer etc.The utility model can make the less and lighter weight of the small product size of production.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of enamel-cover single line.
Being labeled as in the accompanying drawing: 1-enamel-cover single line, 2-copper round wire, 3-first insulating barrier, 4-second insulating barrier.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.155 grades of compound sharp thatch lines of straight weldering based polyurethane/polyamide, constitute as illustrated in fig. 1 and 2, by at least two enamel-cover single lines 1 stranded forming, copper round wire 2 surfaces of every enamel-cover single line 1 are coated with dielectric layers, wherein first insulating barrier 3 is straight weldering based polyurethane lacquer, be coated on copper round wire 2 surfaces, second insulating barrier 4 is polyamide insulating varnish, is coated on the surface of first insulating barrier 3.
Described enamel-cover single line 1 is disposable disc molding and the strands of being twisted into.
Described first insulating barrier 3 and second insulating barrier 4 are molten to be one.
The utility model is by enamel-cover single line applied in two coats insulating varnish (directly weld based polyurethane lacquer and polyamide insulating varnish), make the enamel-cover single line have insulating properties, form by at least 2 enamel-cover single lines are stranded again, therefore make the eddy current and the kelvin effect that produce normal, output impedance is stable, have high thermal endurance class simultaneously, thermal level is 155 grades, is applicable to electricity-saving lamp, LED lamp electronic transformer etc.The utility model can make the less and lighter weight of the small product size of production.
