Description
Technical field
The utility model relates to enamelled stranded-wire technical field, specifically, relates to a kind of nylon composite straight weldering polyurethane enamelled stranded-wire.
Background technology
Enamelled stranded-wire is also litz wire, and it is by the stranded electromagnetic wire of multiply enamelled wire, is widely used in all kinds of high frequency electronic equipment.Enamelled stranded-wire forms because the enamelled wire very thin by many wire diameters is stranded, and greatly increase compared with the single enamelled wire that its surface area is long-pending with traditional same cross-sectional, under high frequency voltage, twisted wire conductive capability obviously promotes.But be form by multiple enamelled wire is stranded just because of enamelled stranded-wire, the twisted wire after completing is withstand voltage also to be reduced greatly, this is caused by by enamelled wire, in line sending, these processes stranded, because of friction, impaired, the pin hole of surperficial paint film increases.Usually, the enamelled stranded-wire that single is stranded, it is withstand voltage reduces by 40% than enamelled wire.In addition, twisted wire is when coiling, and its surperficial paint film also can slightly damaged, have impact on its voltage endurance.
Utility model content
The utility model be for existing straight weldering polyurethane enamel-cover twisted wire in the course of processing, friction causes enamelled wire surface paint film damaged between enamel-cover single line, between single line and guide wheel etc., there is the problem of pin hole increase, withstand voltage reduction in the enamelled stranded-wire after completing, provides a kind of nylon composite straight to weld polyurethane enamelled stranded-wire.
The required technical problem solved of the utility model, can be achieved through the following technical solutions:
A kind of nylon composite straight weldering polyurethane enamelled stranded-wire, described enamelled stranded-wire forms by least two enamel-cover single lines are stranded, it is characterized in that: described enamel-cover single line comprises circular copper wire, described circular copper wire surface arranges straight weldering property polyurethane enamelled coating, and the surface of described straight weldering polyurethane enamelled coating arranges nylon enamelled coating.
In the utility model, the thickness of described straight weldering polyurethane enamelled coating is 2 to 4 times of nylon thickness of paint layer, and for preferably, the thickness of described straight weldering polyurethane enamelled coating is 3 times of nylon thickness of paint layer.
In the utility model, the thickness of described straight weldering polyurethane enamelled coating is 9% to 25% of circular copper wire diameter, and straight weldering property polyurethane paint layer thickness reduces with the increase of circular copper wire diameter.
According to the actual needs, described at least two enamel-cover single lines adopt clockwise direction stranded or counterclockwise stranded.
The utility model nylon composite straight weldering polyurethane enamelled stranded-wire, both the voltage withstand class of enamelled wire can have been ensured, the hardness of coating surface can be increased again and reduce skin-friction coefficient, such enamelled wire is when producing twisted wire, the damage of enameled wire coat greatly reduces, compared with traditional enamelled stranded-wire, the enamelled stranded-wire voltage withstand class after completing also significantly improves, and its voltage endurance capability improves more than 400V than common enamelled stranded-wire.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the cross section structure schematic diagram of the utility model enamelled stranded-wire
Embodiment
In order to make technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
Purport of the present utility model is, by the analysis to existing enamelled stranded-wire manufacture process, find that existing enamelled wire exists the problem that surperficial paint film is impaired, pin hole increases in line sending, these processes stranded because of friction, provide a kind of nylon composite straight to weld polyurethane enamelled stranded-wire by the utility model.
See Fig. 1, for any enamelled stranded-wire, its all by least two enamel-cover single lines around being twisted into, nylon composite straight weldering polyurethane enamelled stranded-wire of the present utility model is no exception, according to actual needs, enamel-cover single line of the present utility model can adopt clockwise direction (S to) stranded, and counterclockwise (Z-direction) also can be adopted stranded, owing to no matter adopting that mode stranded, cross section structure is all identical.Those skilled in the art's strand mode is also known, and is not repeated herein.
Enamel-cover single line of the present utility model comprises circular copper wire 10, circular copper wire 10 surface arranges straight weldering property polyurethane enamelled coating 11, the surface of straight weldering polyurethane enamelled coating 11 arranges nylon enamelled coating 12, straight weldering polyurethane paint has tough, gloss is plentiful, strong adhesion, the characteristic such as water proof and wearable, corrosion resistance, can meet the user demand as coil required on the products such as electromagnetic stove, microwave oven, special transformer, high-speed induction motor.Straight weldering polyurethane enamelled coating 11 ensures the voltage withstand class of enamelled wire, at straight weldering property polyurethane enamelled coating 11 outer surface at compound one deck nylon enamelled coating 12, can increase again the hardness of coating surface and reduce skin-friction coefficient.
In order to make straight weldering polyurethane enamelled coating 11 and the nylon enamelled coating 12 of compound, better can take into account the voltage withstand class of enamelled wire, the hardness of coating surface and skin-friction coefficient, the thickness of straight weldering polyurethane enamelled coating 11 is preferably 2 to 4 times of nylon enamelled coating 12 thickness, for preferably, the thickness of straight weldering property polyurethane enamelled coating 11 is set to 3 times of nylon enamelled coating 12 thickness.
Thickness for straight weldering property polyurethane enamelled coating 11 can not be too little, otherwise can reduce withstand voltage, increase the pinhole number of enamel-cover single line unit length, therefore, in the utility model, the thickness of straight weldering property polyurethane enamelled coating 11 is 9% to 25% of circular copper wire 10 diameter, and straight weldering property polyurethane enamelled coating 11 thickness reduces with the increase of circular copper wire 10 diameter.Like this, namely meet withstand voltage and requirement that is unit length pinhole number, production cost can not be increased because straight weldering property polyurethane enamelled coating 11 thickness is bigger than normal again, and the external diameter after enamelled stranded-wire is completed can not be excessive.
The utility model nylon composite straight weldering polyurethane enamelled stranded-wire, both the voltage withstand class of enamelled wire can have been ensured, the hardness of coating surface can be increased again and reduce skin-friction coefficient, such enamelled wire is when producing twisted wire, the damage of enameled wire coat greatly reduces, compared with traditional enamelled stranded-wire, the enamelled stranded-wire voltage withstand class after completing also significantly improves, and its voltage endurance capability improves more than 400V than common enamelled stranded-wire.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
