[0011] See figure 1 with figure 2 The electrical connector terminal 10 of the present invention is mainly used in plug-in electrical connectors, where the contact area 11 of the terminal 10 is often plugged and unplugged in contact with other electronic components (not shown), so the contact area 11 needs to have good corrosion resistance And abrasion resistance.
[0012] Generally, in order to enhance the corrosion resistance, wear resistance and conductivity of the terminal 10, it is necessary to plate one or more layers of metal on the terminal 10. The base material 20 of the contact area 11 of the terminal 10 is generally bronze or phosphor bronze, or it can be For other copper alloys or other alloys, in order to reduce the contact resistance of the terminal and enhance the corrosion resistance and sliding properties, before the gold plating layer 40 is plated, the first nickel plating layer 30 is plated on the entire surface of the terminal 10 to prevent the terminal 10 fro...
