USB adaptor and data transmission device

一种usb转接头及数据传输设备

Abstract

本发明公开了一种USB转接头及数据传输设备,属于数据传输技术领域。该USB转接头包括:转接头本体、形成在转接头本体内部的USB电路模块和形成在转接头本体内部的控制模块。本公开通过控制模块与USB电路模块电连接,控制模块用于检测并判断第二端口通过数据线缆连接的设备为主设备还是从设备,并根据判断结果控制USB电路模块的工作模式为充电模式、非OTG数据传输模式或OTG数据传输模式,使得本公开的实施例提供的USB转接头可以与数据线配合实现通过主设备为移动设备充电或在主设备与移动设备之间进行非OTG数据传输,也能与OTG线配合实现在移动设备与从设备之间进行OTG数据传输。
The invention discloses a USB adaptor and a data transmission device, and belongs to the technical field of data transmission. The USB adaptor includes an adaptor body, a USB circuit module formed in the adaptor body, and a control module formed in the adaptor body. The control module is electrically connected to the USB circuit module, the control module is used for detecting and determining whether or not a device connected to a second port through a data line is a master device or a slave device, and controlling a working mode of the USB circuit module in a charging mode, a non-OTG data transmission mode or an OTG data transmission mode according to the determination result, and in this way, both the USB adaptor provided by the embodiment of the invention and the data line can charge a mobile device through the master device or perform non-OTG data transmission between the master device and the mobile device, and both the USB adaptor and an OTG line can achieve OTG data transmission between the mobile device and the slave device.
