The nickel aminosulfonate coating coating and the phosphorus and nickel coating can guarantee that the electric connector terminal has certain toughness and corrosion resistance.
Description
[technical field]
The present invention relates to a kind of electric connector terminal, relate in particular to a kind of audio connector terminal.
[background technology]
As a rule, electroplating processes all will be carried out in the electric connector terminal surface, and this mainly is in order to improve electric connector terminal corrosion resistance and contact stabilization.And coating generally comprises nexine for filling and leading up the nickel coating of base material and being covered in surperficial noncorroding metal layer, and this metal level can be gold layer or rhotanium layer.But simultaneously, can scrape the scrape along strain during electric connector terminal docking, also require it to have certain resistance to wear and toughness.
So, be necessary to design a kind of electric connector terminal to overcome aforementioned deficiency.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of electric connector terminal, and it has certain toughness and corrosion resistance.
For solving the problems of the technologies described above, a kind of technical scheme of the present invention is: a kind of electric connector terminal, to be fixed in electric connector, this electric connector terminal comprises that connecting portion, an end connect the holding parts of connecting portion and the elastic portion of extending from the holding parts other end, holding parts is used for electric connector terminal is fixed in electric connector, elastic portion has the contact site for docking, and described electric connector terminal surface is electroplate with nickel coating, sulfamic acid nickel coating and phosphorus nickel coating from the inside to the outside successively.
Compared with prior art, electric connector terminal of the present invention has following effect: sulfamic acid nickel coating and phosphorus nickel coating can ensure that electric connector terminal has certain toughness and corrosion resistance.

Fig. 2 is the schematic diagram of part electric connector terminal section, only illustrates the coating of a side.
The flow chart that Fig. 3 electric connector terminal of the present invention is electroplated.
[embodiment]
Fig. 1, Fig. 2 and Fig. 3 have disclosed electric connector terminal 100 of the present invention and manufacture method thereof.In the present embodiment, electric connector terminal 100 is a kind of audio connector terminals, and it is made by sheet metal.
Please refer to Fig. 1, electric connector terminal 100 comprises that connecting portion 10, an end connect the holding parts 20 of connecting portion and the elastic portion 30 of extending from the holding parts other end, holding parts 20 is used for electric connector terminal is fixed in electric connector (not shown), and elastic portion 30 has the contact site 331 for docking.
Described holding parts 20 is tabular, and its both sides are provided with the hangnail with body (not shown) fixing of electric connector.Holding parts 20 comprises the kink 22 of body 21 and connection connecting portion, and the width of kink 22 is less and L-shaped.
Described connecting portion 10 is used for electric connector terminal 100 is fixed to printed circuit board (PCB) (not shown), and fixed form can be elasticity butt or welding.Adopt welding manner in the present embodiment, connecting portion namely is weld part.Connecting portion 10 comprises the base portion 11 that extends from kink and is positioned at the welding block 12 at base portion center.Described welding block 12 is from the base portion punch forming, and welding block also has the solder side 121 that protrudes from base portion one surface, and welding block 12 is used for electric connector terminal is soldered to printed circuit board (PCB).
Described elastic portion 30 comprises the semicircle arcuation section 31 of extending from holding parts, extends and the elastic arm 32 parallel with holding parts 20 and own elasticity arm 32 tilts to extend and away from the contact arm 33 of holding parts 20 to connecting portion 10 directions from arcus part 31, contact arm 33 rats form above-mentioned contact site 331, contact site 331 is hemispheric overshooting shape, and it cooperates to form electrical connection with banjo (not shown).
The below carries out electroplating processes to electric connector terminal, and specifically referring to Fig. 3, this technical process mainly comprises following step: step 41, and blowing is ready to strip, is connected with some electric connector terminals on the strip; Step 42 is taken off ester, removes the dirt above the strip; Step 43, pickling cleans to remove surface oxide layer to strip; Step 44, nickel plating is immersed whole electric connector terminal in the plating bath (following electro-plating method is also identical), and namely at the plated surface last layer nickel coating 51 of whole electric connector terminal, its thickness is 0.2 ~ 2um, to reduce the terminal surfaces roughness; Step 45, the plating nickel sulfamic acid, at the plated surface last layer sulfamic acid nickel coating 52 of whole electric connector terminal, namely sulfamic acid nickel coating 52 is covered in nickel coating 51, and its thickness is 0.2 ~ 2um, to improve the toughness of electrodeposited coating; Step 46, plating phosphorus nickel, at the plated surface last layer phosphorus nickel coating 53 of whole electric connector terminal, namely phosphorus nickel coating 53 is covered in sulfamic acid nickel coating 52, and its thickness is 0.2 ~ 2um, and this phosphorus nickel coating phosphorus content is 5% ~ 9%, is conducive to improve the corrosion resistance of terminal; Step 47, rewinding.
Referring to Fig. 2, through top electroplating process, whole electric connector terminal 100 from-inner-to-outers are placed with nickel coating 51, sulfamic acid nickel coating 52 and phosphorus nickel coating 53 successively.Also can only be coated with aforementioned three layers of coating at the electric connector terminal outer surface by improving processing procedure, especially at elastic arm 32 and contact arm 33.In order to make electric connector terminal when docking, better be contacted effect, also can electroplate preferably metal of one deck conductivity at above-mentioned hemispheric contact site 331, such as gold or palladium-nickel alloy.Certainly, owing to being positioned at outermost layer phosphorus nickel itself and also having good conductivity, skin is plating no longer also.
