The invention discloses a data interface conversion device, which comprises a first data interface connected with terminal equipment; a second data interface, wherein the detection port of the second data interface is connected with all or a part of the first ports of the first port group of the first data interface, and the data input port of the second data interface is connected with a part or all of the second ports of the second port group of the first data interface; and a third data interface, wherein the power transmission port of the third data interface is connected with the third port group of the first data interface. The third data interface transmits power signals to the terminal equipment through the power transmission port and the third port group. According to the technical scheme of the invention, the technical problem in the prior art that when the terminal equipment is provided with no earphone interface, the terminal equipment cannot be charged at the same time when a user is listening to an audio file can be solved.
Description
technical field [0001] The invention relates to the field of data conversion lines, in particular to a data interface conversion device. Background technique [0002] With the rapid development of smart terminal devices (for example, smart phones), major manufacturers of smart terminal devices are pursuing ultra-thin bodies to improve user experience. However, while pursuing an ultra-thin body, it may be necessary to give up some functions in the initial terminal equipment, for example, abandoning the 3.5mm or 2.5mm headphone audio interface in a smartphone and replacing it with a new USB type C interface . At this time, when the user wants to charge the smart terminal device, the smart terminal device can be charged through the data cable including the USB type C interface. However, when a user wants to listen to an audio file while charging a smart terminal device, the existing data cable including a USB type C interface cannot meet the above requirements. Therefore, th...
