Description

A mobile phone data interface

technical field

The utility model relates to a mobile phone, in particular to an external data interface of the mobile phone.

Background technique

At present, the accessories earphone and microphone of the mobile phone are integrated into one body, and the charging connection line and the data transmission line are integrated into one body. Due to the scattered functions, it is easy for the user to forget to carry it when using it, and data transmission cannot be performed, and it is also very easy for the user to forget to lose it after use. Furthermore, due to the lack of a qualitative standard, the specifications of the sockets used for data transmission in the mobile phone market are different, which is extremely confusing; the data cable is broken and it is not convenient to replace it. So it is necessary to integrate these functions and standardize their specifications.

Utility model content

The purpose of the utility model is to provide a mobile phone data interface, which has the advantages of simple structure and strong versatility.

The utility model is for realizing the above object, and the technical solution that adopts is:

A mobile phone data interface, including a USB socket, the USB socket is connected with a left-channel audio line, a right-channel audio line, a microphone line, and a neutral line; the left-channel audio line, the right-channel audio line, and the microphone line are provided with triple switch, the other working position of the triple switch is respectively connected to the battery positive line, the data line positive line, and the data line negative line; the neutral line is also connected to the battery negative line.

The beneficial effects of the utility model:

This kind of mobile phone data interface can be conveniently used as an audio output interface and a battery charging interface, achieving the purpose of multiple purposes of one interface. In addition, the interface uses a highly versatile USB interface, which is easy to maintain and use.
