Abstract
The utility model relates to a round CCAM (copper clad aluminum-magnesium) wire which is applied to aspects of electric wires, cables and signal transmission lines. The round CCAM wire comprises a copper layer and an aluminum-magnesium wire core, wherein the copper layer is used for knitting a shield, and the aluminum-magnesium wire core is arranged in the copper layer; the copper layer and the aluminum-magnesium wire core are made into a complex through metallurgical combination of coated-welding and physical-stretching. Because the complex formed by the copper layer and the aluminum-magnesium wire core through metallurgical combination of coated-welding and physical-stretching is adopted in the technical scheme, based on the characteristics of an aluminum-magnesium bar, such as easiness in production, high tensile property and high elongation, the effects of easiness in production and improved elongation properties are achieved; and because the aluminum-magnesium wire is light in mass and good in copper-conducting property, the copper layer arranged at the outer layer of a whole conductor and the aluminum-magnesium wire core arranged on the inner wall of the copper layer are mutually combined in a metallurgical manner so as to form a complex, thereby facilitating the improvement of conductivity and achieving the purpose of high tensile strength and light weight. Compared with the conventional similar products, the round CCAM wire disclosed by the utility model has a beneficial technical effect of low cost.
Description
[technical field]
The utility model relates to a kind of wire rod, is meant a kind of round aluminium in copper magnesium line that is used for the braid shielded field that is used for electric wire, cable and signal transmssion line especially especially.
[background technology]
Shielding processing is the requisite operation of whole machining process technical process of existing electric wire, cable and signal transmssion line.When making cable mesh grid and electronic devices and components pin plug-in unit in the existing shielding processing operation; Normal conditions all adopt pure copper wire, but by the thread conductor of this fine copper, the density of the mesh grid on this conductor is big; Cost is high, and overall weight is heavy and big to the copper resource consumption.
[utility model content]
The utility model technical purpose is to provide a kind of in order to solve the problem that above-mentioned prior art exists and help improving conductivity and extension property, be convenient to produce, have the low and lightweight round aluminium in copper magnesium line of cost.
In order to realize above-mentioned technical purpose; The utility model provides a kind of round aluminium in copper magnesium line; Be used for electric wire, cable and signal transmssion line aspect; It comprises the copper layer that is used for braid shielded and is arranged at magnalium core in the copper layer that described copper layer and magnalium core are through the complex of clad welded and physics stretching metallurgical binding.
According to above-mentioned major technique characteristic, described magnalium core is the core that is formed through clad welded and physics stretching metallurgical binding by magnalium bar and copper sheet.
According to above-mentioned major technique characteristic, described copper layer is to be coated on the metallurgy that stretches through physics of magnalium rod outer surface and the outer layer body that forms by the copper strips that utilizes itemize that copper sheet is cut into.
According to above-mentioned major technique characteristic, described copper layer and magnalium core form with concentric circles mode metallurgical binding.
The useful technique effect of the utility model: because of the present technique scheme is to adopt described copper layer and magnalium core to pass through the complex of clad welded and physics stretching metallurgical binding; Owing to utilize easy production, tensile property height and the elongation of magnalium bar high, make to reach to be convenient to produce and improve extension property.Light weight and copper owing to the magnalium line conducts electricity very well again; So will be arranged at outer field copper layer of whole conductor and the mutual metallurgical binding complex of magnalium core that is arranged at copper layer inwall, and help improving electric conductivity, tensile strength height and have lightweight purpose.Compare each other with existing like product, the utlity model has the low useful technique effect of cost.
For purpose, structural feature and function thereof to the utility model have further understanding, conjunction with figs. specifies as follows now:
[description of drawings]
Fig. 1 is the cross sectional representation of circle aluminium in copper magnesium line in the utility model.
[embodiment]
See also shown in Figure 1ly, explain that below in conjunction with a kind of embodiment the utility model provides a kind of round aluminium in copper magnesium line, be used for electric wire, cable and signal transmssion line aspect, it comprises the copper layer 1 that is used for braid shielded and is arranged at magnalium core 2 in the copper layer 1.
Described magnalium core 2 is the cores that formed through clad welded and physics stretching metallurgical binding by magnalium bar and copper sheet.Described copper layer 1 is to be coated on the metallurgy that stretches through physics of magnalium rod outer surface and the outer layer body that forms by the copper strips that utilizes itemize that copper sheet is cut into.Described copper layer 1 forms with concentric circles mode metallurgical binding with magnalium core 2.
Be arranged at peripheral copper layer 1 and form round aluminium in copper magnesium line through clad welded and physics drawing process metallurgical binding with the magnalium core 2 that is arranged in the copper layer 1.When processing and fabricating, at first utilize itemize that copper sheet is cut into copper strips, through clad welded copper strips is evenly coated on the magnalium bar, stretch through physics then, the metallurgical binding of real copper layer 1 and magnalium core 2 forms circle aluminium in copper magnesium line.Described copper layer 1 and the complex of magnalium core 2 through clad welded and physics stretching metallurgical binding.
Because described round aluminium in copper magnesium line is to pass through clad welded by copper layer 1 and magnalium core 2, the metallurgical binding between the formation metallic forms, and electric conductivity is good, tensile strength is high, cost is low so circle aluminium in copper magnesium line integral body has.Electrical transmission owing to circle aluminium in copper magnesium line mainly relies on conductive surface to carry out again, thus combined conducting electricity very well of copper, good-extensibility, the magnalium line is in light weight, and the tensile strength advantage of higher has also overcome the deficiency of copper cash in the prior art simultaneously.
In sum; Because of the present technique scheme is to adopt described copper layer 1 and the complex of magnalium core 2 through clad welded and physics stretching metallurgical binding; Owing to utilize easy production, tensile property height and the elongation of magnalium bar high, make to reach to be convenient to produce and improve extension property.Light weight and copper owing to the magnalium line conducts electricity very well again; So will be arranged at outer field copper layer 1 of whole conductor and the magnalium core 2 mutual metallurgical binding complexs that are arranged at copper layer 1 inwall, and help improving electric conductivity, tensile strength height and have lightweight purpose.Compare each other with existing like product, the utlity model has the low useful technique effect of cost.
