Abstract
The utility model provides an enamelled wire which replaces copper by aluminum, is economical and practical and is easy and also reliable to connect. The enamelled wire comprises a metal wire core and an insulation coating coated at an outer layer of the metal wire core. The enamelled wire is characterized in that the metal wire core comprises an aluminum conductor, wherein an outer layer of the aluminum conductor is coated with a copper conductor, and the insulation coating is coated at an outer layer of the copper conductor. The insulation coating can be a polyester coating, a polyurethane coating or a polyimide coating. The enamelled wire has the beneficial effects that a material in which the copper is coated with the aluminum is formed by adopting the coating of the copper conductor outside the aluminum conductor and is also used as a novel enamelled wire of an inner conductor; the property of the material is between the copper and the aluminum, and the advantages of superior electric conductivity of the copper and light quality of the aluminum are combined; and the enamelled wire has the characteristics of easy connection, reliable connection, light quality, good winding property, economy and high safety and reliability, the copper is replaced by the aluminum, and copper resources with less reserves are saved.
Description
Technical field
The utility model relates to a kind of enamelled wire.
Background technology
At present, enamelled wire has been widely applied to every field, and is also more and more higher for the requirement of enamelled wire, and common enamelled wire has not satisfied the demand in market.The critical role of enamelled wire industry in the national economic development and effect are more and more outstanding, but traditional enamelled wire includes the metal core, this metal core is that fine copper is made, and then this metal core is coated with outward and is covered with insulating coating, and because cathode copper price continuous rise, not only the cost height also is subjected to the restriction of China's copper inadequate resource.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of with aluminium for copper, economical and practical, ease of connection and enamelled wire reliably.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of enamelled wire, include the metal core and be coated on the outer field insulating coating of metal core, it is characterized in that: described metal core includes aluminium conductor, this aluminium conductor skin is coated with copper conductor, and described insulating coating is coated on the copper conductor skin.
Of the present utility modelly further be set to: described insulating coating can be polyester coatings or polyurethane coating or polyimide coating again.
The beneficial effects of the utility model are: adopt to coat copper conductor outside aluminium conductor, constitute copper clad aluminum material, and with this novel enamelled wire as inner wire, its characteristic is between copper aluminium, combine the good electric conductivity of copper and the advantage of aluminium light weight, have ease of connection, connect reliable, light weight, around good, economic, the safe and reliable characteristics of property, for copper, saved the less copper resource of reserves with aluminium.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment includes metal core 1 and is coated on metal core 1 outer field insulating coating 2, described metal core 1 includes aluminium conductor 11, these aluminium conductor 11 skins are coated with copper conductor 12, described insulating coating 2 is coated on copper conductor 12 skins, and this insulating coating 2 is a polyester coatings, in addition, this insulating coating 2 can also be polyurethane coating or polyimide coating, and regular size is 0.01mm-0.40mm.Same size (same line footpath) density of the present utility model be the conventional metals core be fine copper enamelled wire 1/2, very effective to the weight that reduces coil, in the voice coil field, can obviously promote the performance of product.Good dc resistivity is 1.5 times of enamelled wire of fine copper for the conventional metals core, and when resistance was identical, its line directly was approximately 1.2 times of enamelled wire that the conventional metals core is a fine copper.
In the utility model, employing coats copper conductor 12 outside aluminium conductor 11, constitute copper clad aluminum material, and with this novel enamelled wire as inner wire, its characteristic combines the good electric conductivity of copper and the advantage of aluminium light weight between copper aluminium, have ease of connection, connect reliable, light weight, around good, economic, the safe and reliable characteristics of property, for copper, saved the less copper resource of reserves with aluminium.In addition,, therefore have, and needn't as the metal core is the enamelled wire of fine copper, do special processing with the same braze ability of line copper cash because aluminium conductor 11 outer surface copper cash coat the pure copper conductor 12 of one deck.At last, the utility model 30%-50% that also can reduce production costs in some practical field.The utility model can also have other execution modes, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
Claims (2)
1. an enamelled wire includes the metal core and is coated on the outer field insulating coating of metal core, and it is characterized in that: described metal core includes aluminium conductor, and this aluminium conductor skin is coated with copper conductor, and described insulating coating is coated on the copper conductor skin.
2. enamelled wire according to claim 1 is characterized in that: described insulating coating can be polyester coatings or polyurethane coating or polyimide coating.
