Description
Technical field
The utility model is related to a kind of metal material surface coating more particularly to a kind of conducting terminals that data are quickly transmitted
Metal material surface coating.
Background technology
Connector has a decisive role in existing electronic equipment, the biography with electronic device charging and data
It is defeated, but when electronic equipment enters the substances such as water, can damage the electronic equipment, and it is serious when will be unable to normal use.With science and technology
Change and innovation, existing electronic equipment can accomplish waterproof effect, and have fire resistance characteristic have become it is a kind of new
Trend, and the development of waterproof electrical connector also tends to standardize.
Although connector can be designed to waterproof construction in existing scheme, and separate electronic equipment and extraneous contact,
When being stained with Korrosionsmedium on connector, corrosion can be generated to the terminal of connector, influence the use of connector.In addition, with
The low cost of electronic equipment requires, and manufacturing cost must be also reduced for the parts on electronic equipment, to adapt to the hair of client
Exhibition demand.
In view of drawbacks described above, it is really necessary to design a kind of improved metal material surface coating.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of gold with low cost and preferable anticorrosive property
Belong to material surface coating.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of metal material surface coating, the gold
Belong to material surface coating to include bottom copper material, the second layer nickel tungsten that is plated on copper material outer surface, be plated on second layer nickel tungsten
Alloy outer surface third layer silver or silver alloy and be plated on third layer silver or silver alloy upper surface the 4th layer of palladium-nickel alloy.
The utility model further improves as follows：The metal material surface coating is also plated on successively on the outside of palladium-nickel alloy
The layer 5 gold in face and layer 6 rhodium or rhodium ruthenium alloy positioned at layer 5 gold lateral surface.
The utility model further improves as follows：The thickness 20-120u " of the nickel tungsten, the coating of palladium-nickel alloy
Thickness is 10-100u ".
The utility model further improves as follows：The thickness of coating of the rhodium or rhodium ruthenium alloy is 5-60u ".
The utility model further improves as follows：The copper material includes the polishing layers of copper after the polishing treatment of surface.
The utility model further improves as follows：The thickness of the gold is 0-5u ".
Compared with prior art, the beneficial effects of the utility model are as follows：The utility model is by by metal material surface
Coating is plated on nickel tungsten, silver or silver alloy, palladium-nickel alloy on the outside of copper material successively, and metal material surface coating can be improved
Anticorrosive property, and since silver or silver alloy are low with respect to the cost of nickel tungsten and palladium-nickel alloy, thus improving Corrosion Protection
In the case of be more advantageous to reduction manufacturing cost.
Description of the drawings
The structural schematic diagram of metal material surface coating shown in Fig. 1.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Refering to Figure 1, be metal material surface coating schematic diagram, the metal material surface coating from inside to outside, according to
It is secondary to have six layers of coating structure, wherein respectively bottom copper material A1, second layer nickel-tungsten alloy plating A2, third layer silver or silver alloy
A3, the 4th layer of palladium-nickel alloy A4, layer 5 gold A5 and layer 6 rhodium or rhodium ruthenium alloy A6, the thickness 20- of the nickel tungsten A2
The thickness of coating of the thickness 40-200u " of 120u ", the silver or silver alloy A3, palladium-nickel alloy A4 are 10-100u ".This practicality is new
Type by nickel tungsten, silver or the silver alloy, the palladium-nickel alloy that are plated on metal material surface coating successively on the outside of copper material, due to
The setting of silver or silver alloy, the Corrosion Protection for improving metal material coating simultaneously, also further reduced manufacturing cost.
In the present embodiment, the thickness of the gold A5 is 0-5u ", and the thickness of rhodium or rhodium ruthenium alloy A6 are 5-60u ", are led to
Often can be 1-5u " by the thickness of golden A5, to reduce manufacturing cost, golden coating is without too thick.It follows that the utility model
Embodiment, when improving the anticorrosive property of metal material surface coating, due to silver or silver alloy opposite nickel tungsten and palladium nickel
The cost of alloy is low, also can suitably increase the thickness of silver or silver alloy, the thickness of nickel tungsten or palladium-nickel alloy is reduced, to carry
Reduction manufacturing cost is more advantageous in the case of high anticorrosive property energy.
To prevent metal material surface coating blocked up, above-mentioned thickness of coating range, i.e., above-mentioned plating thickness are obtained by experiment
The increase of degree is conducive to the gap for improving coating material itself, solves the leakproofness of coating, but blocked up, can increase electric connector
Thickness, be unfavorable for metal material surface coating for the slimming development on electric connector, and increase manufacturing cost, so
Above-mentioned thickness of coating the thickness for not influencing electric connector simultaneously, more can guarantee preferable sealing effect, prevent from corroding.Certainly,
In the utility model embodiment, above-mentioned copper material surface can be processed by shot blasting, reduce layers of copper gap, improve sealing effect
Fruit improves anticorrosive property.
By many experiments it is found that by taking conducting terminal as an example, certainly, the utility model embodiment can be used for it is any its
In its metal surface coating structure, to improve the Corrosion Protection of metal material.Such as it is by conducting terminal coating A2 nickel tungstens
When 20u ", A3 silver or silver alloy 20u ", A4 palladium-nickel alloy layers are 10u ", the scheme for being relatively free of A3 silver or silver alloy can be improved
2 minutes, when have continue to be coated with A6 rhodium ruthenium alloys be 10u " conducting terminal corrosion resistance reach 10 minutes；Meanwhile if by conductive
When terminal coating is changed to A2 nickel tungstens 80u ", A3 silver or silver alloy 80u " and A4 palladium-nickel alloy layer 50u ", it is increased to 10 points
Clock, and the conducting terminal corrosion resistance that A6 rhodium ruthenium alloys are changed to 30u " reaches 60 minutes；It please join as follows in nickel tungsten and palladium nickel
It is coated with silver alloy between alloy and does not plate the comparison of anticorrosive time of silver alloy.
The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned
Hair, without performing creative labour, made various transformation are all fallen within the scope of protection of the utility model.
