Abstract

The embodiment of the invention provides a machining method for a USB device, the USB device and a mobile terminal. The machining method for the USB device particularly includes the steps that metal materials are subjected to punching forming, so that a formed metal terminal is obtained; the formed metal terminal is subjected to electroplating treatment, and the electroplated metal terminal is obtained; the electroplated metal terminal is subjected to selective surface roughing treatment, and the metal terminal with part of the surface being rough is obtained; and the metal terminal with part of the surface being rough and thermoset plastic materials are subjected to injection molding, and a plastic structure body is obtained; and the plastic structure body and a shell are assembled, so that the USB device finished product is obtained. The electrochemical corrosion resistance of the USB device can be improved, and failures of the USB device caused by electrochemical corrosion are reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for processing a USB device, the USB device and a mobile terminal. Background technique [0002] The Universal Serial Bus (USB, Universal Serial Bus) device of the mobile terminal is mainly used for data transmission between the mobile terminal and external devices, and battery charging of the mobile terminal. With the development of science and technology, the functions of mobile terminals are becoming more and more powerful, the frequency of consumers using mobile terminals is also increasing, and the power consumption of mobile terminals is also increasing accordingly. Therefore, the USB device used to charge mobile terminals The frequency of use is also increasing. [0003] A common USB device may include a plurality of metal terminals, a plastic structural body enclosing the metal terminals, and an iron shell. The processing procedure of the existing scheme ...
