Abstract
The utility model discloses a high-purity silver-plated copper stranded wire, which consists of a plurality of silver-plated copper wires by stranding. A copper conductor is arranged at the center of each silver-plated copper wire; a middle layer is made of high-grade silver materials; and an outer layer is made of high-grade anti-corrosion materials. The high-purity silver-plated copper stranded wire adopting the technical scheme not only replaces traditional silver-plated copper stranded wire production process technique, but also realizes replacement of'a common silver-plated copper stranded wire' by'the high-purity silver-plated copper stranded wire' product. The high-purity silver-plated copper stranded wire has the advantages of extremely soft property, high-temperature resistance, corrosion resistance, low loss, color-change resistance, solderability and the like, thereby needing no mechanical or chemical method to remove anti-corrosion films, decreasing lead internal resistance and resistivity, avoiding over-current heating of leads, heating arc striking and oxidization of contact portions, remarkably improving mechanical performances, simultaneously ensuring signal transmission precision, avoiding malfunction of equipment, prolonging service life and reducing failure rate.
Description
Technical field
The utility model relates to a kind of high-purity silver-plated copper twisted wire.
Background technology
At present, the silver-coated copper wire of company structure is by copper conductor, silver material stranded forming after electroplating.The silver-plated copper twisted wire is mainly used in the high-tech enterprises such as the electric wire, cable, electronic instrument, instrument of war products.But, because of product electric conductivity, brightness and anticorrosion grade, discoloration-resisting, solderability, silver thickness etc. do not reach the shortcomings such as requirement that military enterprise produces special electric product.The phenomenons such as reduction that cause portions of electronics equipment and electronic components useful life.This not only causes difficulty and economic loss to manufacturing enterprise, and seriously restricts the modern high technology Products Development.
Summary of the invention
Existing for overcoming " common silver-plated copper twisted wire " can not effectively guarantee electric enterprise high conductivity, contact resistance is little, and it is wear-resisting etc. not enough, the utility model provides a kind of high-purity silver-plated copper twisted wire, this high-purity silver-plated copper twisted wire can not only improve electric conductivity, anti-wear performance, discoloration-resisting, and solderability is good, reduces problems such as conductor self-heating.
For achieving the above object, the utility model is by the following technical solutions:
The utility model is twisted into high-purity silver-plated copper twisted wire by the multiply silver-coated copper wire, and the silver-coated copper wire centre is a copper conductor, and the intermediate layer is that high-grade silver material, skin are high-grade anti-corrosion material.
Described intermediate layer is high-grade silver material, is that the original silver content of employing is 99.99% No. 1 silver silver material.
Described skin is high-grade anti-corrosion material, is that bright dose of the anti-variable color light of P ROTAC is adopted in outer wear-and corrosion-resistant agent.
Adopt the utility model of technique scheme, not only substituted traditional silver-plated copper strand production Technology, and realized " high-purity silver-plated copper twisted wire " products substitution " common silver-plated copper twisted wire ".The utlity model has splendid softness, high temperature resistant, corrosion-resistant, low-loss, fastness and performance such as can weld, so need not remove corrosion prevention film with machinery or chemical method, reduce lead internal resistance and resistivity, avoiding lead overcurrent heating and contact portion to occur generates heat and beats arc and oxidative phenomena, significantly improved mechanical performance, guarantee the signal transmission simultaneously accurately, make equipment avoid misoperation and life-saving to reduce failure rate.
The utility model can be applied in the silver-plated copper twisted wire manufacturing enterprise widely, for market provides better more high-purity silver-plated copper twisted wire, and improve surface quality and stability quality, thus drive the raising that the whole nation produces silver-plated copper twisted wire industry technology level, filled up domestic blank.
Description of drawings
Fig. 1 is the cross-sectional structural representation of silver-coated copper wire;
Fig. 2 is the local vertical profile structural representation of silver-coated copper wire.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is made of the cylindrical silver-coated copper wire 3 of multiply, silver-coated copper wire 3 centres are copper conductor 1, the intermediate layer is that high-grade silver material 2, skin are high-grade anti-corrosion material 4, thereby form bright silver copper cash 3, be twisted into high-purity silver-plated copper twisted wire by multiply silver-coated copper wire 3 again.
Need to prove that the intermediate layer is high-grade silver material 2, is that the original silver content of employing is 99.99% No. 1 silver material.Skin is high-grade anti-corrosion material 4, is that bright dose of the anti-variable color light of P ROTAC is adopted in outer wear-and corrosion-resistant agent.
Technological process when the utility model prepares is:
The online first time is carried out on the copper conductor surface cleans, and---------------silver-plated in advance---main silver-plated---------process route of shipping is packed in the white inspection of the anti-bright processing of variable color light---take-up---to twisted wire to secondary cleaning to crop in wire drawing in three cleanings to enter alkali cleaning.
Wherein, high-purity silver-plated copper stranding process: it is 99.99% No. 1 silver silver material that the silver-plated material of the internal layer of high-purity silver-plated copper twisted wire adopts original silver content, outer anticorrisive agent 4 adopts bright dose of the anti-variable color light of P ROTAC, two kinds of organic combinations of material, form splendid discoloration-resisting and solderability, make high-grade high-purity silver-coated copper wire through strands.
In addition, anti-variable color film forming step is: the online second time,------secondary dried up the evaporation film-forming once to dry up---be coated with brightener and do preservative treatment---in cleaning in silver-plated finishing back.
Claims (2)
1. a high-purity silver-plated copper twisted wire is twisted into high-purity silver-plated copper twisted wire by the multiply silver-coated copper wire, it is characterized in that: the silver-coated copper wire centre is a copper conductor, and the intermediate layer is that high-grade silver material, skin are high-grade anti-corrosion material.
3. high-purity silver-plated copper twisted wire as claimed in claim 1, it is characterized in that: described skin is high-grade anti-corrosion material, is that bright dose of the anti-variable color light of P ROTAC is adopted in outer wear-and corrosion-resistant agent.
