Universal serial bus (USB) interface structure

Abstract

The invention relates to a universal serial bus (USB) interface structure which comprises a mini public interface and an auxiliary public interface which is detachably connected onto the mini public interface. A plurality of pins are arranged on both the mini public interface and the auxiliary public interface, the auxiliary public interface is connected with the mini public interface to form a standard public interface, a protruding block is arranged on one of the mini public interface and the auxiliary public interface, a bayonet for containing the protruding block is arranged on the other one of the mini public interface and the auxiliary public interface, the protruding block is detachably connected with the inside of the bayonet in a clamped mode, accordingly interfaces in different specifications can be formed through splitting and combination of the mini public interface and the auxiliary public interface to be connected with electronic equipment with the interfaces in different specifications, allocation of different data lines for different electronic equipment is avoided, a user can only change the electronic equipment and does not need to change the data line in use, and the interface structure is convenient to use, economic and environment-friendly.

Description

technical field [0001] The invention relates to a USB interface, in particular to a USB interface structure applicable to different interfaces. Background technique [0002] USB (Universal Serial Bus, Universal Serial Bus) is an external bus standard used to regulate the connection and communication between various electronic devices. [0003] In the USB1.0 specification that was first introduced, electronic devices must be connected to a PC via USB, and exchange data under the control of the PC. Once they leave the PC, the electronic devices cannot communicate with each other. The following specifications such as USB2.0 and USB OTG (On-The-Go) have not only greatly improved the transmission bandwidth, but also freed the USB device from the original master-slave architecture, without the need for a PC as an intermediary, to achieve end-to-end The terminal transmission mode has greatly expanded the application field of USB, from PC peripherals, such as mice and keyboards, to...

AI Technical Summary

Problems solved by technology

[0004] However, with the development of USB technology, there are certain differences in the USB interface structure developed under different USB specifications. Various electronic devices will also adopt different standard interfaces due to their own transmission speed requirements and volume limitations. Therefore, different devices need to be equipped with different USB data cables, which not only causes inconvenience to users, but also wastes resources.
