Description

Mobile data processing connector based on USB interface

technical field

The utility model relates to a mobile memory based on a USB connector, in particular to a mobile data processing connector based on a USB interface, which can replace external plug-in devices at will, and belongs to computer peripheral equipment.

Background technique

USB stands for "Universal Serial Bus", which translates into Chinese as "Unified Serial Bus". This is a relatively new type of interface technology that has been widely used in the PC field in recent years. USB technology consists of three parts: a PC system with a USB interface, system software capable of supporting USB, and devices using a USB interface. After Microsoft launched WIN95/97 in 1997, USB began to enter the actual combat stage, but because this version's support for USB was an external module, it was not until Windows98 was released that the support module for the USB interface really matured day by day. Therefore, in a sense, Win98 has become the "birth mother" of the development and application of USB technology. Due to the simple installation and ease of use, according to the statistics of Dalaquesl, 100 million USB devices have been sold worldwide in 1999 alone, and this figure has increased to 250 million by 2000, and by 2001 this figure Even the most conservative estimates will at least double. "Unified Serial Bus" (USB 2.0) is a computer peripheral connection specification jointly developed by manufacturers in the PC industry, including Compaq, HP, Intel, Lucent, Microsoft, NEC and Philips. The USB 1.1 specification is widely used now, the speed (12Mbps) is about 100 times faster than the standard serial port, supports simultaneous connection of multiple devices, and has a real "plug and play" feature. Because of these benefits, USB is generally favored by peripheral manufacturers.

On the other hand, as a non-volatile storage medium, flash memory - FLASH, because of its incomparable data stability and adaptability to the environment, it is especially able to overcome the shortcomings of floppy drives and floppy disks with complex mechanisms and small storage capacity. At the same time, with the gradual reduction of semiconductor production costs, mobile memory based on USB interface technology and flash storage technology has been widely used. But existing this type of product, its part comprises USB interface, controller, flash memory unit, and controller is electrically connected USB, flash memory, and the exterior is provided with outer casing, and flash memory, controller are fixedly placed in casing, and USB connector The interface protrudes outside the housing. As any finished product, its capacity is fixed. When a large-capacity memory is required, a complete USB memory must be purchased; on the other hand, if any part of the flash memory or the controller fails, the entire USB memory must be discarded. memory. This is not only difficult to meet a variety of different requirements in practical applications, but also will inevitably result in waste.

Therefore, at present, no matter it is a USB flash drive, or a wireless receiving/transmitting device based on USB, or an IC card holder, etc., all have good applications. However, the existing USB-based computer peripherals are fixed independent products without sharing the USB and the controller, and cannot be replaced with each other. Therefore, the application is greatly limited, and a lot of waste is caused.
