Abstract
The utility model relates to a high-strength copper-coated aluminum cable conductor adopted by a coaxial cable, which resolves the technical problem that provided conductors can guarantee the premise of stable transmission performance and are characterized by saving copper resource and having low manufacture cost. The technical scheme is that the high-strength copper-coated aluminum cable conductor comprises a cylindrical base made of aluminum, and the high-strength copper-coated aluminum cable conductor is characterized in that the outer circumference of the cylindrical base is coated with a pure copper metal layer with a thickness of 0.1-0.3mm.
Description
Technical field
The utility model relates to a kind of conductor, especially the high strength copper clad aluminum conductor of coaxial cable employing.
Background technology
During the conductor transmission of high-frequency signal by coaxial cable, can produce " skin effect ", promptly signal code concentrates on conductive surface and flows through; Therefore the performance of conductive surface material has directly determined the transmission performance of coaxial cable.The structure of conventional coaxial cable comprises from outside to inside crust, screen, insulating barrier and the conductor of coaxial coating successively; Conductor in its standard coaxial cable adopts fine copper (claiming oxygen-free copper again) to make substantially, so the copper resource that consumes is more.And according to the principle of " skin effect ", cable in use, that really brings into play transmitting effect has only the very thin one deck copper material in surface, all the other most copper materials have just been born supporting role.Obviously, the structure of conventional coaxial cable is very unreasonable, and not only copper material does not obtain rational Application, causes the wasting of resources, and cable cost can't further reduce.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of coaxial cable conductor is provided, and this conductor should guarantee under the stable prerequisite of transmission performance, has to save copper material resource, characteristics that production cost is low.
The utility model has adopted following technical scheme:
High strength copper cover aluminum cable conductor comprises the cylindrical base made from aluminium, it is characterized in that: the external peripheral surface of this cylindrical base is coated by a fine copper metal level.
Described fine copper metal layer thickness is 0.1-0.3mm.
The beneficial effects of the utility model are: because according to the kelvin effect principle, the utility model only adopts copper material at the skin (being the transmission position of high-frequency signal) of conductor, and adopts aluminium (being generally aluminium matter wire rod) at the cylindrical base (being the non-transmission position of high-frequency signal) of conductor; Not only satisfy the transmission requirement of high-frequency signal fully, guaranteed the electric property of cable, and effectively reduced copper material consumption (copper material consumption reduces more than 30%), rationally utilized resource, reduced production cost simultaneously; Thereby has a vast market prospect.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, high strength copper cover aluminum cable conductor described in the utility model comprises the cylindrical base made from aluminium matter wire rod 2: the external peripheral surface of this cylindrical base is coated by a fine copper metal level 1.Described fine copper metal layer thickness is preferably 0.1-0.3mm.
When the utility model was made, described fine copper metal level 1 can be positioned at the surface of cylindrical base by coating drawing process, perhaps by electroplating technology attached to the cylindrical base surface.Coat drawing process or electroplating technology and be the existing conventional production technology.
Concrete manufacture process is: the cylindrical base of aluminium matter wire rod carries out cleaning, drying behind unwrapping wire, the sizing earlier; Simultaneously the fine copper plate is cut into strip, cleaning, drying behind the unwrapping wire; Again strip fine copper plate vertically is coated on the surface of cylindrical base, then with weld seam welded closure (coat good conductor semi-finished product diameter this moment and be about 3-4mm); Afterwards the conductor semi-finished product are drawn to required diameter (conductor diameter of coaxial cable is generally about 1mm); Carry out line flaw detection again, detect.Also can directly plate one deck fine copper (existing mature technology is not described in detail) by electroplating work procedure at its outer surface then earlier with cylindrical base unwrapping wire, sizing, the cleaning, drying of aluminium matter wire rod, thickness of coating is determined according to actual conditions.
