Abstract

The invention provides a USB interface transfer device which realizes interconnection of a MINI USB interface and a standard USB interface. Particularly, the invention provides the USB interface transfer device, comprising a USB interface and the MINI USB interface. The USB interface is connected with the MINI USB interface via a cable. The USB interface comprises a first power pin, a first positive data line, a first negative data line and a first grounding pin. The MINI USB interface comprises a second power pin, a second positive data line, a second negative data line, a second grounding pin and a control pin. The first power pin, the first positive data line, the first negative data line and the first grounding pin of the USB interface are correspondingly connected with the second power pin, the second positive data line, the second negative data line and the second grounding pin of the MINI USB interface via the cable. The control pin is at least connected with one of the second power pin or the second grounding pin. Applying the USB interface transfer device of the invention can conveniently connect a USB device and a MINI USB device to reach the aim of intercommunicating.

Description

technical field [0001] The present invention relates to a switching device, in particular to a switching device of a USB interface. Background technique [0002] With the development of science and technology, computers are widely used in various fields, and the communication between computers and peripheral devices is often realized through the USB interface, so there are many peripheral devices related to the USB interface, but various peripheral devices are subject to their own Due to the limitation of conditions, different types of USB ports are used, such as the USB ports on digital cameras. Due to the relatively small size of digital cameras, MINI USB ports are usually used for better layout; and plasma) have added a USB interface to realize the playback of multimedia programs such as pictures, music, movies, etc., but some high-end TVs also add a MINI USB interface. It can be seen from this that with more and more related electronic products, many electronic devices ...
