Abstract
The utility model relates to a nickel-plating and silver-plating copper clad steel conductor wire core for a special cable; a wire body of the wire core consists of a plurality of single wires, and each single wire sequentially comprises four metal layers, wherein the inner layer is matrix material (1), the second layer is a copper layer (2), the outermost layer is a silver layer (4), and a nickel layer (3) is arranged between the copper layer (2) and the silver layer (4). The nickel-plating and silver-plating copper clad steel conductor wire core for the special cable comprises a plurality of strands of wires, thus not only being high in strength, good in extensibility and bending property and low in communication signal loss, but also having high-temperature and discoloration property, corrosion resistance and electromagnetic compatibility.
Description
Technical field
The utility model relates to a kind of special cable with nickel-plated and silver-plated copper covered steel conductor core, and it mainly is to be used for fields such as electronics, space flight and aviation, medicine equipment.
Background technology
In modern industry and national defense construction, the instructions for use that is used for high-frequency signal transmission and some special cables is more and more higher, good electrical conductivity should be arranged, have very high anticorrosion, performance requirement such as high temperature resistant again, usually silver-coated copper wire that adopts and silver-copper plated steel clad wire all rely on the solution of thickening silver layer, silver thickness outward appearance jaundice, metachromatism still can occur through high-temperature test in 420 ℃, 10 minutes, and increase cost of goods manufactured when 2 μ m are above.The development technical merit of China's high-frequency signal transmission cable, high-temperature cable can not satisfy the new markets demand far away at present, China's technology in this respect far lags behind external advanced country, closely the product of half needs from external import, along with China's rapid economic development, special trade is disconnected to the apparent rapid growth of the demand rank of above-mentioned cable, and market demand is with the speed increase in every year 20%.China is used for domestic construction for about 2,000,000,000 yuan from external import every year.Existing market is badly in need of that a kind of resistance to corrosion is strong, good conductivity, cable inner conductor material that high temperature resistant rank is high.
Summary of the invention
The utility model provides a kind of special cable with nickel-plated and silver-plated copper covered steel conductor core, and this multi cord not only intensity height, extensibility and bending is good, and the communication signal loss is little, and heat-resisting quantity discolouration, corrosion resistance and Electro Magnetic Compatibility.
The utility model has adopted following technical scheme: a kind of special cable is with nickel-plated and silver-plated copper covered steel conductor core, its line body is made up of some single lines, every single line comprises four layers of metal level successively, wherein internal layer is a basis material, basis material is the carbon structure steel, the second layer is the copper layer, and outermost layer is a silver layer, is provided with nickel dam between copper layer and silver layer.
Some single lines are by the regular stranded or capable line body that connects to form of bundle heave in.
The utlity model has following beneficial effect: the utility model selects for use nickel as silver-copper separator, the resistance to corrosion of metallic nickel is strong, thermal endurance, plasticity and good toughness, chemistry good stability alive, effectively prevented the atom diffusion between silver, the copper, prevented that it from generating alloy-layer and having influence on its conductivity and corrosion resistance.Make the interface of silvering clear simultaneously, well guaranteed its conductivity, improved the resistance to elevated temperatures of product greatly.When silver thickness during at 1 μ m, through high temperature ageing nondiscolouring, non-yellowing in 420 ℃, 30 minutes, and also the consumption of having saved precious metal greatly, save argent more than 50%, effectively reduced production cost.

Embodiment
In Fig. 1, the utility model is a kind of special cable with nickel-plated and silver-plated copper covered steel conductor core, and its line body is made up of some single lines, and some single lines are by the regular stranded or capable line body that connects to form of bundle heave in.Every single line comprises four layers of metal level successively, and wherein internal layer is a basis material 1, and basis material 1 is the carbon structure steel, and the second layer is a copper layer 2, and outermost layer is a silver layer 4, is provided with nickel dam 3 between copper layer (2) and silver layer 4.
The invention also discloses the manufacture method of a kind of special cable, it is characterized in that it may further comprise the steps with nickel-plated and silver-plated copper covered steel conductor core: step 1, selecting the carbon structure steel for use is basis material 1, and basis material 1 is carried out electrolytic copper plating; Step 2, basis material 1 carries out multiple tracks moulding drawing by the mould diamond mould again, and then carries out the heat treatment first time through forming copper layer 2 behind the electrolytic copper plating; Heat treatment for the first time is for eliminating internal stress annealing, its process is the material after the drawing in the step 2 to be put into empty well formula annealing furnace be warmed to 500-600 ℃, carries out 12 hours constant temperature then and sets, and carries out insulation in 24 hours behind constant temperature again, temperature descends gradually, when dropping to room temperature material is taken out; Step 3 is handled formation nickel separator 3 with carrying out electrolytic ni plating through the material after the heat treatment for the first time in the step 2; Step 4 is carried out the silver-plated processing of electrolysis once more with the material of handling through electrolytic ni plating in the step 3 and is formed silver layer 4; Step 5 will be carried out multiple tracks moulding drawing by mould again through silver-plated back material, carry out the heat treatment second time again, carry out drawing system light by the mould diamond mould at last, form Φ 0.025mm monofilament; Also for eliminating internal stress annealing, its process is the material after the drawing in the step 5 to be put into the vacuum well type annealing furnace be warmed to 500-600 ℃ in heat treatment for the second time, and the time of carrying out constant temperature is 12 hours, and the time of insulation is 24 hours.Carry out constant temperature then and set, be incubated behind constant temperature again, temperature descends gradually, after dropping to room temperature material is taken out.
Claims (2)
1. a special cable is with nickel-plated and silver-plated copper covered steel conductor core, its line body is made up of some single lines, it is characterized in that every single line comprises four layers of metal level successively, wherein internal layer is basis material (1), basis material (1) is the carbon structure steel, the second layer is copper layer (2), and outermost layer is silver layer (4), is provided with nickel dam (3) between copper layer (2) and silver layer (4).
