Computer external equipment connection protection device

Abstract

The invention discloses a computer external equipment connection protection device, which comprises a frame cover, a slot is formed in the bottom of the frame cover; a first word lamp which is arranged at the top of the frame cover; a second word lamp which is arranged at the top of the frame cover; a time relay which is arranged on the side wall in a through groove; a first conduction device which comprises a moving block, two symmetrically arranged first metal blocks, a first swing block, a first spring, a first connecting rod mechanism, a stop lever and a first driving device for driving the moving block to move up and down; a second conduction device which comprises a second swing block, a second spring, a second connecting rod mechanism and two symmetrically arranged second metal blocks, and the two second metal blocks are arranged in the frame cover; a baffle which is arranged in the frame cover and penetrates through the through groove; and a second driving device which drives the baffle to move leftwards or rightwards, so that the first slot or the second slot is communicated with the through groove. The device can prevent the confidential equipment and the non-confidentialequipment from being connected with the case at the same time, so that the problem of virus infection of the confidential equipment and the influence on data security are avoided.

Description

technical field [0001] The invention relates to the technical field of computer external equipment protection, in particular to a computer external equipment connection protection device. Background technique [0002] At present, the external conversion interface of the computer main box generally includes interfaces such as USB interface, RS232 interface and earphone. Any external standard device can be plugged into the connection, which is a great threat to some computers that need to be kept secret. If you accidentally insert a confidential device and a non-secure device into the computer, it is easy to cause a virus on the confidential device Infection affects data security, and if the computer device is set as a special connection security device, it will lead to cumbersome computer applications and high maintenance costs for confidential data, which is not conducive to data maintenance and management.
