Description
[technical field]
The present invention relates to a kind of electric connector terminal, relate in particular to a kind of Board-to-Board Electrical Connector terminal.
[background technology]
Present stage, solder technology generally is divided into two kinds of surface soldered technology, piercing welding technology, and no matter be that which kind of solder technology all is to utilize scolder to assist welding, but many problems can appear like this, such as climbing tin, revealing bad phenomenon such as weldering or empty weldering.
A kind of electric connector terminal is made of metal and slabbing roughly, said electric connector terminal have a base portion and from said base portion to one of extending below weld part, said weld part periphery is electroplate with a metal level.Said electric connector terminal utilizes scolder to be soldered on the circuit board; When said electric connector terminal is soldered to said circuit board; Said scolder is fused into liquid state through heat, and part is adsorbed on the said metal level of said weld part, and another part is adsorbed on the said circuit board; According to this said weld part is soldered on the said circuit board, to form electrical path.When said weld part is soldered on the said circuit board; Said scolder can be adsorbed on the said metal level after heat is fused into liquid state; But, cause said metal level to be not easy control within the specific limits, so the same bad control range of said scolder because molten metal has diffusion phenomena in the brush plating process; Therefore in welding process, be prone to cause and climb the tin phenomenon, and then cause failure welding.
So, be necessary to design a kind of electric connector terminal and combination thereof to overcome aforementioned deficiency.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of electric connector terminal, climbs the tin phenomenon when it can suppress to weld preferably.
For solving the problems of the technologies described above; The present invention has disclosed a kind of electric connector terminal, is to be fixed in electric connector, and this electric connector terminal comprises that weld part, an end connect the holding parts of weld part 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 contact site, and the surface of said weld part, holding parts and elastic portion all is electroplate with metal level, also is coated with solder mask on the metal level of holding parts.
Compared with prior art, electric connector terminal of the present invention has following effect: at the holding parts of electric connector terminal spraying solder mask, climb the tin phenomenon in the time of can effectively suppressing to weld.

[embodiment]
Embodiment one:
Please with reference to Fig. 1, shown in 2; The present invention is a kind of electric connector terminal 10; Be fixed in electric connector, it comprises horizontal weld part 11, from the vertically extending holding parts 12 of weld part 11 1 ends and be positioned at the elastic portion 13 of the holding parts other end, and holding parts 12 is used for when terminal is installed on the plastic cement body (not shown) of electric connector, interfering with each other with the plastic cement body and terminal being fixed in the plastic cement body; Elastic portion is to form " U " shape by the metal bending to insert space 130; Insert in it for the terminal of butt connector, the reverse bending of the free terminal of elastic portion 13 and protruding into is inserted space 130 forming contact site 131, and elastic portion 13 then can form another contact site 132 at another side arm of contact site 131 relatively; Certainly, this another side arm also can play elastic reaction and contactless function.Fig. 3 has shown to have the preceding terminal band 40 of plurality of terminals cutting; Some electric connector terminals 10 are bent to form by a sheet metal punching press; It is connected in strip 20 by weld part 11; After electric connector terminal was installed on plastic body, strip 20 was removed at the line of cut place, and the weld part 11 between the terminal is also broken off each other.
Electric connector terminal 10 in use can with to connected components (not shown) repeated friction, so contact jaw 131,132 needs corrosion resistance and resistance to wear preferably.The base material of electric connector terminal 10 is generally bronze, phosphor-copper or other copper alloy, and corrosion resistance, resistance to wear and the conductivity in order to strengthen electric connector terminal 10 needs electroplated metal layer on its contact site usually.
Please with reference to Fig. 1,2, in the present embodiment, metal level comprises nickel coating and gold plate (being coated in terminal surfaces, not shown), and gold plate is covered in nickel coating.Promptly elder generation is at the surface of weld part 11, holding parts 12 and the elastic portion 13 of electric connector terminal 10 plating one deck nickel coating; Oxidized to prevent electric connector terminal; Influence its service behaviour; Plate one deck gold plate again in the holding parts 12 and the elastic portion 13 of electric connector terminal 10 then, can improve the corrosion resistance and the conductivity of electric connector terminal 10.At last, adopt ink-jet technology, prevent that the scolder that melts in weld part 11 from flowing in the slit between electric connector terminal and the plastic cement body, thereby avoid climbing the generation of tin phenomenon at holding parts surface spraying solder mask 30.In this execution mode, solder mask 30 adopts high-molecular organic material to process, and solder mask 30 mainly is sprayed on the face that closely cooperates of holding parts 12 and electric connector.Such as, solder mask 30 shown in Figure 1 mainly is 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 spray solder mask.
In conjunction with Fig. 3,4,, need carry out following steps in order to give electric connector terminal 10 nickel plating, gold-plated and ink-jet: step 61, blowing is ready to terminal band 40; Step 62 is taken off ester, removes the dirt above the terminal band 40; Step 63, pickling, subband 40 cleaning and removing in opposite end are removed surface oxide layer; Step 64, nickel plating plates one deck nickel coating on the surface of whole electric connector terminal 10; Step 65, gold-plated, plate one deck gold plate again on the nickel coating surface of holding parts 12 and elastic portion 13, promptly gold plate is covered in nickel coating; Step 66, ink-jet sprays one deck solder mask 30 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 cover holding parts 12 fully, also can cover a wherein part.Here the solder mask 30 of spraying is a kind of high-molecular organic material; Step 67, rewinding.
Above-mentioned nickel coating and gold plate can guarantee that electric connector terminal 10 has good electrical conductivity, corrosion resistance and resistance to wear, climb the tin phenomenon when solder mask then can prevent electric connector terminal 10 welding.
Embodiment two:
See also Fig. 5, the distinctive points of present embodiment and embodiment one is: one, the metal level that plates of elastic portion is a nickel coating; Two, step 65 is different with the front and back order of step 66.After completing steps 64 nickel plating, carry out step 66 earlier, ink-jet; That is spray one deck solder mask 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 cover extension fully, also can be sprayed at a wherein part.In the present embodiment, the solder mask of spraying is a kind of high-molecular organic material, and solder mask only is sprayed on the mating surface of holding parts and plastic body.And then carry out step 66, and gold-plated, promptly at the nickel coating plated with gold coating on contact site 131 surface.When can suppressing to weld, solder mask climbs the tin phenomenon.
