Interface, USB plug and mobile terminal

Abstract

The present invention belongs to the technical field of electronics, and discloses an interface. The interface comprises a plurality of base pins arranged in turn along a depth direction of the interface, the base pins comprise first base pin groups and second base pin groups, the first base pin groups are used for connection with an audio interface circuit while the second base pin groups are used for connection with a USB interface circuit, the first base pin groups and the second base pin groups also comprise public base pins, and the public base pins are connected with the audio interface circuit or the USB interface circuit through a switching circuit. A corresponding USB plug and a mobile terminal which are applied to the above interface are also provided. Plugged connection of the interface becomes simple and convenient, and size occupation of conventional USB interfaces is saved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an interface, a USB plug and a mobile terminal. Background technique [0002] Under the influence of the trend of thinner and lighter mobile terminals, manufacturers regard the thickness control of mobile terminals as an important design requirement. [0003] In view of the wide variety of mobile terminal interfaces, for example, the volume of the existing USB2.0 interface is about 120mm 3 , the volume of the existing USB3.0 interface is about 192mm 3 , occupies the internal space of the mobile terminal to a certain extent, and hinders the product design of the mobile terminal. [0004] However, the existing USB ports all have a fool-proof design and must be inserted from the front. When plugging in a USB device, the user needs to identify the pros and cons of the USB plug before inserting it, which affects the user experience. Contents of the invention [0005] In order...
