Abstract
The utility model discloses a conducting wire, particularly a conducting wire used for winding electromagnetic coils, which comprises an insulating layer [1] on the outer surface of the conducting wire and a conducting wire positioned on the inner side of the insulating layer [1]. The utility model is characterized in that the conducting wire on the inner side of the insulating layer [1] is composes of an aluminum core wire [3] and a copper layer [2] which is coated on the outer side of the aluminum core wire [3]. Because the conducting wire on the inner side of the insulating layer is a copper-clad aluminum conducting wire formed by the combination of two kinds of metal material, the inner aluminum core wire has the advantages of light weight and low cost, and the copper layer on the outer surface of the aluminum core wire has the advantage of good electric conductivity. Because the electrical transmission of conductors is carried out mainly by means of the outer surfaces of the conductors, the utility model combines the superior electric conductivity of copper with the advantages of light weight and low cost of aluminum, and the utility model overcomes the defects of the copper or the aluminum when the copper or the aluminum is used as electromagnetic wires.
Description
Technical field:
The utility model relates to a kind of lead, particularly a kind of lead that is used to twine solenoid.
Background technology:
In motor, electrical equipment, electronics, electrical instrument, telecommunication installation and high-frequency apparatus, be extensive use of solenoid at present, the lead of existing composition solenoid is that electromagnetic wire all is to adopt copper cash or aluminum steel as inner wire, its appearance has a layer insulating, claims insulating varnish usually.This electromagnetic wire has following shortcoming: though copper cash conducts electricity very well, its density is big, price is high, causes the coil overall weight big, the product cost height; Though aluminum steel is in light weight, price quite copper is low, and its electric conductivity is bad, and the intensity of aluminum steel is also undesirable.
Summary of the invention:
The purpose of this utility model provides that a kind of cost is low, electric conductivity is good, lightweight electromagnetic wire, is used to twine solenoid, overcomes the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of solenoid lead, it comprises the insulating barrier 1 of lead appearance and is positioned at the lead of insulating barrier 1 inboard that it is characterized in that: the lead of insulating barrier 1 inboard is made up of aluminum core line 3 and the copper layer 2 that is coated on aluminum core line 3 outsides.
The utility model compared with prior art, because the lead of insulating barrier inboard is the copper cladding aluminum conductor that is combined by two kinds of metal materials, aluminum core line in it has advantage in light weight, that cost is low, the copper layer of aluminum core line appearance has the advantage of good conductivity, again because the electrical transmission of conductor mainly relies on the conductor outer surface to carry out, so the utility model combines in light weight, the advantage that cost is low of the good electric conductivity of copper and aluminium, has overcome copper or the aluminium deficiency as electromagnetic wire.
Description of drawings:
Fig. 1 is the sectional schematic diagram of the utility model embodiment.
Embodiment:
As shown in the figure: 1 is insulating barrier, the insulating varnish that adopt in the prior art more.The lead of insulating barrier 1 inboard is to be composited by aluminum core line 3 and the copper layer 2 outside it, when processing and fabricating, can select for use the metallic cover welding equipment to carry out stretch forming, promptly twine clad welded and stretching with copper strips, copper is combined with the metallurgy of aluminium, form copper-clad aluminum conductor in the appearance of aluminum core line 3.
Claims (1)
1, a kind of solenoid lead, it comprises the insulating barrier [1] of lead appearance and be positioned at the inboard lead of insulating barrier [1], it is characterized in that: the inboard lead of insulating barrier [1] is made up of aluminum core line [3] and the copper layer [2] that is coated on outside the aluminum core line [3].
