Abstract
The utility model provides a tin-plated copper-coated Al-Mg alloy shielding braided conductor, wherein the interior of the braided conductor is provided with an Al-Mg alloy core (1) and the outside of the Al-Mg alloy core (1) is coated with a copper layer (2). The ratio of the cross-sectional areas of the copper layer (2) to the Al-Mg alloy core (1) is 2:25-1:11. The copper-coated Al-Mg alloy core is further plated with a layer of tin (3), so that the conductor is excellent in electric conductivity just as copper material, light in specific gravity and low in price as Al-Mg alloy, and good in stability as tin material. Therefore, the tin-plated copper-coated Al-Mg alloy shielding braided conductor can be widely used as shielding braided conductors for radio-frequency cables, leakage cables, computer cables and other data cables. Compared with the original pure copper conductor, the tin-plated copper-coated Al-Mg alloy shielding braided conductor is more excellent, more economic and safer.
Description
Technical field
The utility model relates to a kind of plain conductor, particularly is fit to radio frequency cable, reveals a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor that cable, computer and other data cable inner shield line are used.
Background technology
in the market as radio frequency cable, reveal cable, computer and other data cable shielding braid wires be generally pure copper wire, this not only makes enterprise face the cost pressure of continuous rising because the copper valency is high, simultaneously, what work is only conductive line surfaces because of actual in current delivery, the electric conductivity quality of the material of wire inside is insignificant, therefore actual as the shielding braid line with fine copper is a kind of waste, and fine copper is done shielding material easily fracture in the braiding process, welding difficulty between litzendraht wire, thereby fine copper easily with cable in the stability that the impact of sulphur chemically reactive conducts electricity of dissociating.Therefore market is in the urgent need to a kind of more economical, better shielding braid conductor material.
Summary of the invention
The purpose of this utility model is to provide that a kind of good conductivity that has copper concurrently has again the material of aluminium light, price is low and a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor of the stability of tin.
The technical solution adopted in the utility model is: a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor, comprise appearance tin layer and the wire that is positioned at the inboard of tin layer, it is characterized in that: the wire of tin layer inboard is comprised of Al-Mg alloy core and the copper layer that is coated on Al-Mg alloy core, and affiliated copper layer and the sectional area ratio of Al-Mg alloy core are 2: 25-1: 11.Making the cable shield litzendraht wire with existing fine copper compares, this wire not only has the lightweight low price of good conductivity, almag of copper, and make the welding between litzendraht wire easier after zinc-plated, can avoid simultaneously free sulphur chemically reactive out in copper and cable, thereby affecting the problem of electric conductivity, is a kind of more economical, better, safer shielding braid wire material.
Description of drawings
Fig. 1 is structural representation of the present utility model
Concrete execution mode
As shown in Figure 1, by Al-Mg alloy core 1 be coated on Al-Mg alloy core 1 and form with the copper layer 2 of Al-Mg alloy core metallurgical binding, copper layer 2 dispatch from foreign news agency are coated with tin layer 3; Copper layer 2 is 2 with the sectional area ratio of Al-Mg alloy core 1: 25-1: 11.During making, first with coated copper layer 2 after Al-Mg alloy core 1 alkali cleaning, through welding and stretching, make copper layer 2 and Al-Mg alloy core 1 carry out metallurgical binding, form the copper clad aluminum magnesium alloy heart yearn, then adopt zinc-tin technique to electroplate one deck tin layer 3 on the aluminium in copper magnesium material, thereby form a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor that has more good cost performance.
Claims (2)
1. tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor, comprise the wire that appearance tin layer (3) and tin layer (3) are inboard, it is characterized in that: the inboard wire of tin layer (3) is by Al-Mg alloy core (1) and is coated on copper layer (2) formation on Al-Mg alloy core (1).
2. a kind of tin-coated copper-clad aluminum-magnesium alloy shielding braided line conductor according to claim 1, it is characterized in that: the sectional area ratio of described copper layer (2) and Al-Mg alloy core (1) is 2: 25-1: 11.
