Abstract
The present invention relates to a partial gold electric plating method for a box-structure jack contact member of an electric connector. Firstly, parent metal nickel is plated on a whole bronze belt in electric plating; then, a thick gold layer with the thickness of 1.27 micrometer at least is plated on a specified position in partial selective electric plating, after stamping forming, a thin gold layer with the thickness of 0.25 micrometer at least is plated on one side of an engaging end in partial selective electric plating; finally, a layer of tin-lead alloy with specified thickness is plated on one side of a terminal in electric plating. In stamping procedure, the thin gold layer is formed in the contact member positioned in a work area, and the terminal (can adopt welding, wire wrapping or compression joint) is plated with tin or tin-lead alloy in electric plating. The present invention has the advantages that the abrasive resistance between female and male contact members is ensured, the salt mist resistant requirement of the whole contact member can be satisfied, and simultaneously, the cost is reduced.
Description
Technical field
The present invention relates to a kind of printed board electric connector, especially refer to the jack contact of electric connector.
Background technology
As shown in Figure 1, box type structure jack contact of electric adopts stamping technology to make, and the first half 1 profile is a cuboid, and the inside is hollow, resembles a box, indent 2 around the cuboid.The latter half 3 is welding endss.
Contact is the core of electric connector, can divide negative contact and positive contact, generally by brass or bell metal through machining or be stamped to form, then according to the certain thickness gold, silver of different needs electroplating surface, tin etc., to increase corrosion resistance.
In the use occasion of having relatively high expectations, need to electroplate a bed thickness gold, at least 1.27 microns, the purpose of doing like this is in order to increase the resistance to wear between the positive and negative contact, to keep the electrical contact performance of electric connector in whole life cycle.
Adopt the contact of drawing, in order to save the precious metal that resembles a golden class, usually carry out the selective electroplating technology in the world, promptly, electroplate tin-lead alloy at terminals at the service area (the engagement position of feminine gender and positive contact) of same contact electrogilding.For negative contact, all there is coating in the inside and outside portion in its service area, and because point effect, the thickness of outside gold plate is greater than the thickness of inner gold plate, and outside gold plate to the contact performance of contact, resistance to wear less than influence, so outside gold plate does not have value, be a kind of waste.
Summary of the invention
The object of the present invention is to provide a kind of parcel plating gold method of box type structure jack contact of electric of electric connector, to reduce cost.
The parcel plating gold method of the box type structure jack contact of electric of a kind of electric connector provided by the present invention is characterized in that: at first, be with plating underlying metal nickel at whole bronze; Then, thick gold at least 1.27 microns of the local selective electroplating thickness in regulation position, at the thin gold of at least 0.25 micron of end of engagement one side selective electroplating thickness, the regulation position is after the drawing: this thick gold layer is formed in the contact inside that is positioned at the working region in the punching course; At last, electroplate the tin-lead alloy of specific thickness in terminals one side.
In above-mentioned parcel plating gold method, described terminals are welding terminals, solderless wrapped connection terminals or crimping terminals.
Adopted above-mentioned technical solution, both guaranteed the resistance to wear between the yin, yang contact, can satisfy the salt spray resistance requirement of whole contact again, reduced cost simultaneously.
Description of drawings
Fig. 1 is the structural representation of existing box type structure jack contact of electric.
Embodiment
Basic thought of the present invention comes from: the negative contact of box type structure jack contact of electric, adopt Sheet Metal Forming Technology to make by bell metal, in order to save precious metal, elder generation's thick gold of parcel plating on bronze is with before the punching press, at least 1.27 microns of thickness, this bed thickness gold is formed in contact inside in the punching course, just in time is positioned at the working region, end of engagement one side is electroplated the thin gold of one deck after the drawing, and terminals one side is electroplated tin-lead alloy.
The parcel plating gold method specific implementation method of the box type structure jack contact of electric of electric connector of the present invention is as follows:
At first, be with plating underlying metal nickel at whole bronze;
Then, at the thick gold of at least 1.27 microns of the local selective electroplating thickness in regulation position, after the drawing at the thin gold of at least 0.25 micron of end of engagement one side selective electroplating thickness;
At last, electroplate the tin or the tin-lead alloy of specific thickness in terminals one side.
Above-mentioned regulation position is: this thick gold layer is formed in the contact inside that is positioned at the working region in the punching course.
Terminals (can adopt welding, solderless wrapped connection or crimping) electrotinning or tin-lead alloy.
Though the inventive method is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the present invention, also can make the variation and the modification of various equivalences under the situation that does not break away from spirit of the present invention.Therefore, if in connotation scope of the present invention to the variation of above-mentioned example, modification all will drop in the scope of claims of the present invention.
Claims (2)
