Description
[technical field]
The present invention relates to a kind of electric connector terminal, particularly relate to a kind of Board-to-Board Electrical Connector terminal.
[background technology]
Present stage, solder technology is generally divided into surface soldered technology, piercing welding technology two kinds, regardless of be which kind of solder technology be all to utilize solder to carry out auxiliary welding, but so there will be many problems, such as climb the bad phenomenon such as stannum, dew weldering or missing solder.
A kind of electric connector terminal, is made of metal and substantially slabbing, and described electric connector terminal has a base portion and one of downwardly extends weld part from described base portion, and described weld part periphery is electroplate with a metal level.Described electric connector terminal utilizes solder to be soldered on circuit board, when described electric connector terminal is soldered to described circuit board, described solder is fused into liquid through high-temperature heating, partial adsorbates is on the described metal level of described weld part, another part is adsorbed on described circuit board, according to this described weld part is soldered on described circuit board, to form conductivity pathway.When described weld part is soldered on described circuit board, described solder can be adsorbed on described metal level after high-temperature heating is fused into liquid, but owing to during brush plating, molten metal has diffusing phenomenon, described metal level is caused to be not easily controlled within the specific limits, therefore the described same bad span of control of solder, therefore in welding process, easily cause phenomenon of solder rising, and then cause failure welding.
Thus, it is necessary to a kind of electric connector terminal of design and combinations thereof is to overcome aforementioned deficiency.
[summary of the invention]
The technical problem to be solved is to provide a kind of electric connector terminal, and it can preferably suppress phenomenon of solder rising during welding.
For solving above-mentioned technical problem, present invention is disclosed a kind of electric connector terminal, it is affixed to electric connector, this electric connector terminal includes weld part, the holding parts in connecting welding portion, one end and the elastic extended from the holding parts other end, holding parts is for being fixed on electric connector by electric connector terminal, elastic has contact site, and the surface of described weld part, holding parts and elastic is plated with metal level, and the metal level of holding parts is also coated with solder mask.
Compared with prior art, electric connector terminal of the present invention has following effect: the holding parts at electric connector terminal sprays solder mask, can effectively suppress phenomenon of solder rising during welding.

[detailed description of the invention]
Embodiment one:
nullRefer to Fig. 1、Shown in 2，The present invention is a kind of electric connector terminal 10，It is fixed on electric connector，It includes horizontal weld part 11、From the vertically extending holding parts in weld part 11 one end 12 and the elastic 13 that is positioned at the holding parts other end，Holding parts 12 is for interfering with each other with plastic body when terminal is installed on plastic body (not shown) of electric connector and terminal being fixed on plastic body，Elastic is to be bent by metal and form " u "-shaped and insert space 130，Terminal for butt connector is inserted therein，The free terminal of elastic 13 reversely bends and protrudes into insertion space 130 to form contact site 131，Elastic 13 then can form another contact site 132 at another side arm of relative contact site 131，Certainly，This another side arm also can play elastic reaction and contactless function.Fig. 3 shows the terminal band 40 before having the cutting of some terminals, some electric connector terminals 10 are bent to form by a sheet metal punching press, it is connected to material strip 20 by weld part 11, after electric connector terminal is installed on plastic body, material strip 20 is removed at line of cut, and the weld part 11 between terminal is also disconnected from each other.
Electric connector terminal 10 in use can rub with to connected components (not shown) repeatedly, and therefore contact jaw 131,132 needs preferable corrosion resistance and wearability.The base material of electric connector terminal 10 generally bronze, phosphor-copper or other copper alloy, generally for strengthening the corrosion resistance of electric connector terminal 10, wearability and electric conductivity, need on its contact site electroplated metal layer.
Refer to Fig. 1,2, in the present embodiment, metal level includes nickel coating and gold plate (being coated in terminal surfaces, not shown), and gold plate is covered in nickel coating.One layer of nickel coating of plated surface of i.e. first weld part 11, holding parts 12 and elastic 13 at electric connector terminal 10, to prevent electric connector terminal oxidized, affect its service behaviour, then holding parts 12 and elastic 13 at electric connector terminal 10 plate one layer of gold plate again, can improve corrosion resistance and the electric conductivity of electric connector terminal 10.Finally, use ink-jet technology at holding parts surface spraying solder mask 30, prevent melting the solder in weld part 11 and flow in the gap between electric connector terminal and plastic body, thus avoid the generation of phenomenon of solder rising.In the present embodiment, solder mask 30 uses high-molecular organic material to make, and solder mask 30 is mainly sprayed at the closely cooperating on face of holding parts 12 and electric connector.Such as, the solder mask 30 shown in Fig. 1 is mainly sprayed on the inner surface 121 of holding parts；If side, outer surface 122 closely cooperate with plastic body, this side, outer surface 122 also need to spray solder mask.
In conjunction with Fig. 3,4, in order to electric connector terminal 10 nickel plating, gold-plated and ink-jet, need to follow the steps below: step 61, blowing, terminal band 40 is ready to；Step 62, de-ester, remove terminal band 40 dirt above；Step 63, pickling, terminal band 40 is cleaned and removes surface oxide layer；Step 64, nickel plating, at the plated surface last layer nickel coating of whole electric connector terminal 10；Step 65, gold-plated, plate one layer of gold plate again on the nickel coating surface of holding parts 12 and elastic 13, i.e. gold plate is covered in nickel coating；Step 66, ink-jet, one layer of solder mask 30 is sprayed again on the surface of holding parts 12, in the horizontal direction, this solder mask extends horizontally to the both sides of the edge of holding parts 12, and in the vertical direction, solder mask 30 can be completely covered holding parts 12, it is also possible to covers a portion.Here the solder mask 30 sprayed is a kind of high-molecular organic material；Step 67, rewinding.
Above-mentioned nickel coating and gold plate can ensure that electric connector terminal 10 has good electric conductivity, corrosion resistance and wearability, and phenomenon of solder rising occurs when solder mask is then possible to prevent electric connector terminal 10 to weld.
Embodiment two:
Referring to Fig. 5, the present embodiment is with the distinctive points of embodiment one: one, the metal level that elastic is plated is nickel coating；Two, step 65 is different from order before and after step 66.After completing step 64 nickel plating, first carry out step 66, ink-jet, that is one layer of solder mask is sprayed again on the surface of electric connector terminal holding parts 12, in the horizontal direction, this solder mask extends to the both sides of the edge of holding parts 12, and in the vertical direction, solder mask can be completely covered extension, it is also possible to is sprayed at a portion.In the present embodiment, the solder mask of spraying is a kind of high-molecular organic material, and solder mask is only sprayed at the coordinating on face of holding parts and plastic body.Carry out step 66 the most again, gold-plated, i.e. at the nickel coating plated with gold coating on contact site 131 surface.Solder mask can suppress, during welding, phenomenon of solder rising occurs.
