Problems solved by technology

[0003] Although the terminals made by this electroplating method can ensure good electrical conductivity between the terminal feet and the terminals, it cannot guarantee the wear resistance and corrosion resistance of the contact parts of the terminals, especially for the terminals of the test socket connector.

Embodiment Construction

[0011] see figure 1 and figure 2 , the electrical connector terminal 10 of the present invention is mainly used in a plug-in type electrical connector, wherein the contact area 11 of the terminal 10 is often plugged and contacted with other electronic components (not shown), so the contact area 11 needs good corrosion resistance and abrasion resistance.

[0012] Usually, in order to enhance the corrosion resistance, wear resistance and conductivity of the terminal 10, one or more layers of metal need to be plated on the terminal 10, and the base material 20 of the contact area 11 of the terminal 10 is generally bronze or phosphor copper, and can also be For other copper alloys or other alloys, in order to reduce the contact resistance of the terminal, enhance 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 from being damaged...

Abstract

This invention relates to one terminal suitable for plug-in connector terminals, which comprise base materials and each coating layer with at least one metal coating layer and nickel layer. The coating method comprises the following steps: providing base materials and processing the terminal by off-line processing; processing the acid clearing on terminals; processing the electrical coating on the base materials; coating step composed of gold coating and nickel coating.

Description

【Technical field】 [0001] The invention relates to a terminal and an electroplating method thereof. 【Background technique】 [0002] In a general electrical connector, in order to have good electrical conductivity when the terminal pin contacts the electrical connector terminal, the contact area needs to be plated with metal. In actual operation, it is necessary to plate nickel on the surface of the substrate first, and then plate a layer of gold. For example, US Patent No. 5,307,562 published on May 3, 1994 with the title of "Method For Making Contact" discloses a method of first nickel-plating and then gold-plating on the terminal. In addition, U.S. Patent No. 6,451,449 published on September 17, 2002 with the title of "Terminal Material And Terminal" also discloses a terminal in which the surface of the terminal substrate is first plated with nickel and then plated with gold. In the above patents, a layer of gold is plated on the basis of nickel plating to increase the co...
