Embodiment 1

[0024] Embodiment 1: see figure 1 , an electroplating coating for the terminal 9, which includes a copper coating 8 electroplated on the surface of the terminal 9, the surface of the copper coating 8 is sequentially electroplated with an inner nickel-tungsten coating 7, an inner gold coating, a palladium coating 3, an outer gold coating and rhodium ruthenium Plating 1. Preferably, an outer nickel-tungsten plating layer 5 and an intermediate gold plating layer are also provided between the inner gold plating layer and the palladium plating layer 3 .

[0025] Since the terminal 9 is generally made of copper material to provide the signal transmission performance and electrical conductivity of the terminal 9; a layer of copper plating 8 is electroplated on the surface of the terminal 9, which can be closely combined with the terminal 9, and at the same time a relatively flat electroplating layer is formed on the surface of the terminal 9. Avoid tip effects. The nickel-tungsten ...

Embodiment 2

[0037] Embodiment 2: A terminal 9, the surface of which is plated with the electroplating layer of Embodiment 1.

[0038] Terminal 9 may be a terminal in the current electronic interface.

Embodiment 3

[0039] Embodiment 3: An electronic interface includes the terminal 9 of Embodiment 2.

[0040] The electronic interface may be various data connection line interfaces, such as a USB interface; it may also be an electronic interface of an electrical connector, or other interfaces for signal transmission or conduction.

Abstract

The invention relates to an electroplating clad layer used for a terminal, the terminal, an electric interface and an electric device. The electroplating clad layer includes a copper coating layer electroplating on the surface of the terminal. The surface of the copper coating layer is electroplated with an inner nickel-tungsten coating layer, an inner gold coating layer, a palladium coating layer, an outer gold coating layer and a rhodium- ruthenium coating layer. According to the invention, by arranging the nickel-tungsten coating layer, the palladium coating layer and the rhodium- ruthenium coating layer the abrasion resistance, the corrosion resistance and the rigidity and electric contact performance of the terminal can be improved effectively, so that the service lifetime of the terminal is prolonged.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to an electroplating coating for a terminal, a terminal, an electronic interface, and an electronic device. Background technique [0002] With the continuous popularization of smart devices, their use frequency is getting higher and higher; when smart devices such as mobile phones and tablets are in use, their interfaces can be used as charging interfaces or data transmission interfaces, and the interfaces are often connected with data lines. Plugging and unplugging, and the interface is often touched by hands. After a long time of use, it is easy to cause corrosion or wear of the terminal of the interface, which will affect the service life of the smart device. Contents of the invention [0003] The object of the present invention is to provide an electroplating layer for terminals to address the shortcomings of the prior art, and the electroplating layer can effectively p...
