Abstract

The utility model discloses a composite silver-plated copper wire with high conductivity and brightness, which comprises a copper conductor in the center, a high-class sliver material in the middle layer and a high-class anticorrosive material in the outer layer. The composite silver-plated copper wire adopting the technical scheme has excellent flexibility, high temperature resistance, corrosion resistance, low loss, color change resistance, weldability and the like, thereby an anticorrosive film can be removed without mechanical or chemical methods, internal resistance and resistivity of the conductor are reduced, overcurrent heating of the conductor and heated arc strike and oxidation of a contact part can be avoided, and the mechanical property is improved evidently. Further, the composite silver-plated copper wire guarantees signal transmission precision simultaneously, avoids malfunction for equipment, prolongs service life, and reduces failure rate.

Description

The bright compound silver-gilt copper wire of high leaded light

Lean on the art field

The utility model relates to the bright compound silver-gilt copper wire novel process technology of a kind of high leaded light, specifically is exactly the bright compound silver-gilt copper wire of high leaded light.

Background technology

At present, the silver-gilt copper wire of company structure is to be formed through electroplating by copper conductor, silver material.Silver-gilt copper wire is mainly used in electronics, electric, the household electric appliances.But, do not reach the shortcomings such as requirement of special electric product because of the uniformity of product brightness and anticorrosion grade, discoloration-resisting, solderability, silver thickness, continuity etc., cause the damage of portions of electronics industry institute electrogenesis subset and electronic components, phenomenons such as the reduction in useful life cause difficulty and economic loss for the electric enterprise of production.

Summary of the invention

Can not effectively guarantee electric enterprise high conductivity in order to overcome existing silver-gilt copper wire, contact resistance is little, and it is wear-resisting etc. not enough, the utility model provides a kind of high leaded light bright compound silver-gilt copper wire, the bright compound silver-gilt copper wire of this high leaded light can not only improve electric conductivity, anti-wear performance, discoloration-resisting, and silver thickness evenly, continuity and solderability be 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 centre is that copper conductor, intermediate layer are 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, have 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, avoid lead overcurrent heating and contact portion to occur and generate heat and beat 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.

To sum up, the utility model not only can be applied to transducer control cable, the electronic component of electronic enterprises widely, and the common silver-gilt copper wire of having realized the multiple platform silver-gilt copper wire products substitution of superconduction light.Thus, the utility model can be widely applied in the silver-gilt copper wire manufacturing enterprise, for market provides better more superconduction light compound silver-gilt copper wire, and improves surface quality and stability quality, thereby drive the raising that the whole nation produces silver-gilt copper wire industry technology level, filled up domestic blank.

Description of drawings

Fig. 1 is the cross-sectional structural representation of the superconduction compound silver-gilt copper wire of light;

Fig. 2 is that the compound silver-plated copper of superconduction light part is cutd open structural representation in length and breadth.

Embodiment

As shown in Figure 1 and Figure 2, electroplate the high-grade silver material 2 of one deck at copper conductor 1 outer surface, outermost surface is coated with high-grade anti-corrosion material 3, forms the compound silver-gilt copper wire 4 of superconduction light.Wherein, high-grade silver material 2 is that the original silver content of employing is 99.99% No. 1 silver silver material, high-grade anti-corrosion material 3 is meant that the agent of outermost layer wear-and corrosion-resistant is bright dose of the anti-variable color light of P ROTAC, two kinds of organic combinations of material have formed the compound bright silver-gilt copper wire of superconduction, thus the compound high-grade enamelled wire with splendid discoloration-resisting and solderability.

Preparation technology of the present utility model is:

The online first time is carried out on the copper conductor surface cleans, and---------------silver-plated in advance---master is silver-plated, and---the novel process route of shipping is packed in bright preservative treatment---take-up---self check to secondary cleaning to crop in three cleanings to enter alkali cleaning.

Wherein, compound silver plating process: be that to adopt original silver content be 99.99% No. 1 silver silver material to the silver-plated material of the bright compound silver-gilt copper wire internal layer of high leaded light, outer anticorrisive agent adopts bright dose of the anti-variable color light of P ROTAC, and two kinds of materials are organically in conjunction with forming the splendid discoloration-resisting and the compound high-grade silver-gilt copper wire of solderability.

Film-forming step: after the online second time silver-plated the finishing---cleans that---secondary dries up the evaporation film-forming once to dry up---be coated with brightener and do preservative treatment---, the multiple platform silver-gilt copper wire of superconduction light by this novel process production, through testing conductive performance, anti-wear performance, discoloration-resisting, the indexs such as continuity of silver thickness uniformity, solderability, corrosion prevention film reach the demand of special electronic and electrical equipment and bundle twisted wire.

Claims
