The housing can be designed into a variety of beautiful styles to improve the appearance of the cell phone.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a mobile terminal extension device for data transmission. Background technique [0002] With the development of technology, developers or users not only pay attention to the running speed of electronic products, but also pay equal attention to the appearance, weight and hand experience of the products. Therefore, while enterprises are developing new electronic products, developers have also made improvements to audio interfaces, data interfaces, and USB connectors, so that there are multiple connectors distributed on various products. In order to reduce the size of the mobile terminal, the design of the current mobile terminal interface has gradually realized the integration of various interface functions. For example, the newly released Apple mobile phone has canceled the audio interface, and the integrated design of the audio interface and charging port. , so that th...
