Abstract
The utility model relates to a copper-cladding aluminum enameled flat wire which comprises a coating, wherein the conductor arranged inside the coating is a copper-cladding aluminum conductor; the outer layer of the copper-cladding aluminum conductor is a copper conductor, while the inner core is an aluminum conductor; moreover, the cross-sectional area of a flat wire is between 2mm<2> and 28mm<2>. The utility model replaces copper by aluminum, thereby saving the copper resource; meanwhile, the utility model has the advantages of easy and reliable connection, light weight, excellent flexibility and economy, and is as safe and reliable as a copper wire.
Description
Technical field:
The utility model relates to a kind of enamelled wire.
Background technology:
In recent years, the critical role of enamelled wire industry in the national economic development and effect are more and more outstanding, but traditional fine copper enamelled wire uses fine copper to make raw material mostly, and because cathode copper price continuous rise, cost height not only, and be subjected to the restriction of china natural resources shortage.
The utility model content:
The purpose of this utility model is to provide a kind of copper cover aluminum enameled sheet wire,, economizes on resources for copper with aluminium, have ease of connection, connect reliable, light weight, good, economical around property, with copper cash safe and reliable advantage equally.
For achieving the above object, the solution that the utility model is taked is: a kind of copper cover aluminum enameled sheet wire, and it comprises coating, and the coating inner wire is a copper clad aluminum conductor, and the skin of copper clad aluminum conductor is that copper conductor, inner core are aluminium conductor, lenticular wire sectional area 2mm
2-28mm

The utility model is to adopt copper clad aluminum material to make the novel enamelled wire of inner wire, its characteristic is between copper aluminium, combine the good electric conductivity and the lightweight advantage of aluminium of copper, have ease of connection, connect reliable, light weight, good, economical around property, with copper cash safe and reliable characteristics equally,, economize on resources for copper with aluminium.
Description of drawings:
Fig. 1 is the front view of present embodiment.
Fig. 2 is the cross-sectional structure schematic diagram of present embodiment.
Among the figure: 1, copper conductor, 2, aluminium conductor, 3, coating.
Embodiment:
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of copper cover aluminum enameled sheet wire, it comprises coating 3, and coating 3 inner wires are copper clad aluminum conductor, and the skin of copper clad aluminum conductor is that copper conductor 1, inner core are aluminium conductor 2, lenticular wire sectional area 2mm
2-28mm
2
Directly select ring rolling piece and drawing die according to copper-clad aluminum conductor, carry out 2 moulds, 3 moulds and combination machine drawing and stretch.According to production of copper alclad wire gauge lattice, annealed, change the wire internal crystal structure, then insulating varnish is coated in wire surface, making lead enter burner hearth again cures, with solvent evaporation and make and paint film and solidify, form the uniform paint film of thickness at wire surface, form the finished product enamelled wire through lubricated back take-up drum at last.
The utility model can be made the enamelled wire of various different models according to different needs, as polyester, polyurethane, polyimide enameled wire etc.The copper-in-aluminum enameled wire density of same size (same cross-sectional is long-pending) is 1/2 of enamel covered wire, and is very effective to the weight that reduces coil, in the voice coil field, obviously enhances product performance.Good dc resistivity: be 1.5 times of enamel covered wire, when resistance was identical, its sectional area was approximately 1.2 times of enamel covered wire.Good braze ability: because its surface of inner wire coats with one heart one deck fine copper, therefore have, do special processing the pure copper wire and needn't resemble with the same braze ability of pure copper wire.Low cost: compare with enamel covered wire, 30%-50% can reduce production costs in some use field.
Claims (1)
1. copper cover aluminum enameled sheet wire, it comprises coating (3), it is characterized in that: coating (3) inner wire is a copper clad aluminum conductor, the skin of copper clad aluminum conductor is that copper conductor (1), inner core are aluminium conductor (2), lenticular wire sectional area 2mm
2-28mm
