USB (Universal Serial Bus) interface for realizing falling prevention by utilizing electrorheological fluid

Abstract

The invention relates to the technical field of computer protection equipment, and provides a USB (Universal Serial Bus) interface for realizing falling prevention by utilizing an electrorheological fluid, which comprises a USB interface and is characterized in that a plug is fixedly connected to the center of the USB interface, extrusion rubber is fixedly connected to the inner side of the USB interface through the plug, and a fastening device is movably connected to the inner side of the USB interface. According to the USB interface for realizing falling prevention by using a electrorheological fluid, a connector is placed in the center of the plug to extrude the extrusion rubber on the two sides, the extrusion rubber is made of a rubber material and has a certain fixing effect, a computer provides electric power as drive after connection, and the electric power circulates in an electrorheological fluid suspension body through a conductive wire. According to the principle of electrorheological fluid, namely the electrorheological fluid can generate liquid-solid conversion under the action of an electric field, the electrorheological fluid is in a liquid state when the intensity of the external electric field is greatly lower than a certain critical value, and the electrorheological fluid is changed into solid when the intensity of the electric field is greatly higher than thecritical value.

Description

technical field [0001] The invention relates to the technical field of computer protection equipment, in particular to a USB interface that utilizes current variants to prevent falling off. Background technique [0002] The USB interface refers to a serial bus device that connects the computer system and external devices. It is also an input and output interface. It is widely used in information communication products such as personal computers and mobile devices. Due to the wide application of the USB interface, then Its development prospects in the market are relatively good. [0003] Due to long-term use of the commonly used USB interface, the socket will become loose, causing the computer to fail to accept valid data, and when the staff is working, there will also be cases where the foot touches the USB due to lack of attention. When this kind of thing When it happens, the files inside the storage may be destroyed, and every time the user manually inserts the plug into ...

Problems solved by technology

[0003] Due to long-term use of the commonly used USB interface, the socket will become loose, causing the computer to fail to accept valid data, and when the staff is working, there will also be cases where the foot touches the USB due to lack of attention. When this kind of thing When it happens, the files inside the storage may be destroyed, and every time the user manually inserts the plug into the USB interface, the impurities in the air will pass into the USB interface, and the use of electronic machinery will be affected by dust. It will shorten the service life of the USB interface. In order to solve the above problems, the inventor proposed a USB interface that uses current variation to prevent falling off.
