Problems solved by technology

[0006] However, in this way, the contact between the metal plate and the PCB is electrically connected. When the contact between the metal plate and the PCB is oxidized, the characteristics of the antenna will deteriorate.
The two cannot be fully contacted, and the consistency in mass production is difficult to guarantee
[0007] For the above-mentioned problems in related technologies, no effective solution has been proposed yet

Abstract

The invention provides a USB (Universal Serial Bus) interface and a terminal, wherein the USB interface comprises: a USB jack which is fixedly connected to a first metal piece; the first metal piece which is connected to a second metal piece through a first rotating shaft, wherein when the USB jack is rotated, the USB jack drives the first metal piece to rotate by a first predetermined angle through the first rotating shaft; and the second metal piece for electrical connection with the grounding surface of the mainboard of the printed circuit board (PCB) of the terminal. With the technical scheme provided in the invention, the problems of poor antenna properties and the like existing in the implementation scheme of the USB interface of the terminal in a related technology are solved; and therefore, the electrical connection between the terminal and a computer is improved and the properties of the antenna of the mobile terminal are improved.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a USB interface and a terminal. Background technique [0002] With the development of modern communication technology, wireless networks have been widely used, and mobile communication terminals have also been vigorously developed. Various mobile communication terminals continue to appear, with different shapes and smaller and smaller volumes. In the design, the ground plane of the printed circuit board (PCB for short) is used as a resonant unit of the antenna, and the length is not less than 1 / 4 of the working wavelength λ. Therefore, when the length of the PCB ground plane is less than 1 / 4 of the operating wavelength λ, it means that the performance of the communication terminal antenna will deteriorate. Usually, the bottleneck of the length of the PCB ground plane is caused by the Universal Serial Bus (USB for short). ) is determined by the lowest frequency at which th...
