The invention provides the electric connector terminal with strong oxidation resistance and the electroplating method thereof.
Description
[technical field]
The present invention relates to a kind of electric connector terminal and electro-plating method thereof.
[background technology]
Existing electric connector terminal is that base material is to provide mechanical performance required elastic force with the high property copper alloy, corrode under applied environment for fear of base material, can plate one deck gold plate again in termination contact portion and installation portion then in substrate surface plated with nickel coating, increase the conductivity of terminal.Be to have disclosed the method for after nickel plating on the terminal, plating one deck gold again in No. the 5th, 307,562, the United States Patent (USP) of " terminal manufacturing method (Method ForMaking Contact) " as the denomination of invention of on May 3rd, 1994 bulletin.In addition, the denomination of invention of on September 17th, 2002 bulletin is also to have disclosed gold-plated again terminal after the nickel plating of terminal substrate surface in No. the 6th, 451,449, the United States Patent (USP) of " terminal material and terminal (Terminal Material AndTerminal) ".All be on the nickel coating of terminal, to have plated one deck gold in the above patent, increase the conductivity and the non-oxidizability of terminal.
The terminal non-oxidizability that this electro-plating method is made is not strong, and holding time long back nickel coating still can be oxidized, and oxide layer can cause the installation portion failure welding of terminal, and causes terminal surfaces resistance to increase.Especially for the high frequency terminal, its signal electric current is mainly in its Surface runoff, and oxide layer is unfavorable for the stability of high-frequency signals transmission.
Therefore, be necessary to provide a kind of improved electric connector terminal and electro-plating method thereof, to overcome above-mentioned defective.
[summary of the invention]
Technical problem to be solved by this invention is: strong electric connector terminal of a kind of non-oxidizability and electro-plating method thereof are provided.
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, it comprises base material and is plated on each coating on the base material, coating comprise organic oxidation-resistant coating and be plated on base material and organic oxidation-resistant coating between nickel coating.
For solving the problems of the technologies described above, another kind of technical scheme of the present invention is: a kind of electro-plating method of terminal, and it comprises: the step that base material is provided; Terminal is carried out the step of ungrease treatment; Terminal is carried out the step of pickling; Step at the enterprising electroplating of base material; The step of this plating comprises the step of nickel plating and further is coated with the step of machine oxidation-resistant material.
Compared with prior art, the coating of electric connector terminal is provided with organic oxidation-resistant coating in the technique scheme, and it can more effectively prevent the nickel coating oxidation, reduces the generation of oxide layer.

[embodiment]
Fig. 1 and Fig. 2 illustrate two kinds of electric connector terminals 1,1 ', include with the contact site 11 of other electronic building brick (not icon) plug contact, be installed on the installation portion 13 of circuit board (not icon) and be connected the main part 12 of contact site 11 and installation portion 13.Electric connector terminal 1,1 ' generally with copper alloy as base material (also can be other metal or alloy certainly), electroplate each coating on the base material.
Fig. 3 illustrates the coating of contact site 11, is coated with nickel coating 21 on the base material 20, electroplates one deck gold plate 22 on the nickel coating 21, to increase conductivity.Fig. 4 illustrates the coating of main part 12 and installation portion 13, coating on the base material 20 comprise organic oxidation-resistant coating 23 and be plated on base material 20 and organic oxidation-resistant coating 23 between nickel coating 21, organic oxidation-resistant coating 23 is the outermost layer of each coating, can effectively prevent nickel coating 21 or other coating oxidation.In the present embodiment, nickel coating 21 is plated on the surface of base material 20, and organic oxidation-resistant coating 23 is plated on the nickel coating 21 then, and cost is also lower when increasing non-oxidizability.Certainly, also can between nickel coating 21 and organic oxidation-resistant coating 23, plate one deck gold, increase conductivity in installation portion 13.
Please, go up each coating of plating, need through following steps in order to give electric connector terminal 1,1 ' in conjunction with consulting Fig. 5: step 31, blowing is about to base material 20 and is ready to; Step 32, the dirt on the base material 20 is removed in degreasing; Step 33, pickling is cleaned the removal oxide layer to base material 20; Step 34 is at base material 20 enterprising electroplatings; Step 35, rewinding.
Please in conjunction with consulting Fig. 6, the step 341 that is included in nickel plating on the base material 20 in the step 34 of electroplating on the contact site 11 reaches further gold-plated step 342 on nickel coating 21.Please in conjunction with consulting Fig. 7, the step 34 of electroplating on main part 12 and installation portion 13 is included in the step 341 of nickel plating on the base material 20 and further is coated with the step 343 of machine oxidation-resistant material, is coated with the final step of the step 343 of machine oxidation-resistant material for the step 34 of plating.Gold-plated step 342 and be coated with the mode that adopts brush plating in the step 343 of machine oxidation-resistant material, escapable cost.
