USB data line

Abstract

The invention provides a USB data line. The USB data line comprises a power line, a ground line, a data line, a USB interface end and a data line body, wherein the USB interface end comprises a light-emitting module for supplying illumination and a power supply reshaping module for processing a power supply, wherein the light-emitting module and the power supply reshaping module are connected with the power supply line and the ground line in parallel. The USB data line solves the technical problem that USB charging is convenient to use in a dark environment; the USB data line is simple, practical and low in cost; and the USB data line gives consideration to the flexibility of application and diversity of application scenarios.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a USB data line. Background technique [0002] The full name of USB is Universal Serial Bus, which is Universal Serial Bus in Chinese. As an interface that regulates the connection and communication between computers and peripherals, it has made great contributions to the popularization and development of computer technology since its birth. With its plug-and-play convenience, flexible expansion, high-speed data transmission, and bus power supply, USB has rapidly occupied the fields of consumer electronics, mobile devices, smart instruments, and industrial control. With the practicality of the USB3.1 standard including Type-C (see Table 1), USB can be expanded into power supply, VGA, HDMI, etc. to realize bidirectional data transmission and audio and video playback. It can be seen that the update and progress of USB technology makes it have broad development prospects in t...

AI Technical Summary

Problems solved by technology

[0008] With the popularization and in-depth development of USB, a problem that follows is: From the perspective of consumption behavior, people tend to use mobile devices such as mobile phones and tablets during the day, and use USB to charge these devices during breaks. This will encounter a problem, it is difficult for us to find the USB interface on the correct mobile device and connect it accurately in a dark environment

[0011] 1. It needs to work only when the mobile phone has power;

[0012] 2. The light brightness is too low when working, and the light is dark;

[0013] 3. Limited by the design of the structure and appearance, the distance between the keyboard light and the USB port is far;

[0014] 4. Need software to work together
