Abstract
The utility model relates to the technical field of enamelled wires, in particular to a copper clad aluminum enamelled wire, which comprises an aluminum inner core and a copper layer which is coated on the aluminum inner core, wherein the outer surface of the copper layer is coated with an anti-oxidation protection layer, and the surface of the anti-oxidation protection layer is also coated with an insulation layer. The copper clad aluminum enamelled wire has strong solvent resistance, higher tensile strength, better anti-oxidation property, good lacquer film consistency, stable product quality and good product forming property and can meet the high temperature resistance requirement.
Description
Technical field
The utility model relates to the technical field of enamelled wire, especially a kind of copper-in-aluminum enameled wire.
Background technology
At present, in the production field of enamelled wire, can use the material of copper cover aluminum to replace pure copper material to produce enamelled wire as conductor cores, and its outer surface generally only applies the single or multiple lift paint film as insulating barrier, this kind enamelled wire is after being made into coiling group or coil molding, its heat resistance is poor, a little less than the solvent resistance, and easily coat of paint is produced aging effect.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, a kind of thermal endurance, solvent resistance are provided and are difficult for producing aging copper-in-aluminum enameled wire.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of copper-in-aluminum enameled wire, comprise aluminium inner core and the copper layer that is coated on the aluminium inner core, and be coated with the protection against oxidation layer on the copper layer outer surface, the surface of protection against oxidation layer also is coated with insulating barrier.
In order to prevent the aging of copper catalysis coat of paint, described protection against oxidation layer is a tin coating.
In order to reach best insulation effect, described insulating barrier is the polyester enamelled coating.
This copper-in-aluminum enameled wire is mainly used in modern electric device, the electronic component coil, as: the coil of the coil of motor, the coil of transformer, closing motor and the high slightly motor coil of heatproof.
The beneficial effects of the utility model are, copper-in-aluminum enameled wire of the present utility model, and it is strong to have solvent resistance, also have advantages of higher tensile strength, anti-oxidation preferably characteristics are arranged in addition in addition, the paint film high conformity, product with stable quality can satisfy high temperature resistant requirement, and product shaping is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. aluminium inner cores among the figure, 2. copper layer, 3. protection against oxidation layer, 4. insulating barrier.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Copper-in-aluminum enameled wire as shown in Figure 1; comprise aluminium inner core 1 and the copper layer 2 that is coated on the aluminium inner core 1, be coated with protection against oxidation layer 3 on copper layer 2 outer surface, the surface of protection against oxidation layer 3 also is coated with insulating barrier 4; protection against oxidation layer 3 is a tin coating, and insulating barrier 4 is the polyester enamelled coating.
Copper-in-aluminum enameled wire of the present utility model is compared with the copper enamelled wire, and it has higher tensile strength, and electric conductivity is better, therefore more near the modern electrical machine industry to enamelled wire in high requirement that mechanical properties proposed.
Copper-in-aluminum enameled wire of the present utility model is fit to the high speed spooling equipment to be used, with the various high performance form-wound coils of coiling.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
