Abstract

The invention discloses a USB interface isolation device, and relates to the technical field of USB interface safety. The invention relates to a USB (universal serial bus) card reader which comprises a shell (1), a USB plug (2) and a USB interface (3) which are arranged on the shell (1) and electrically connected, and further comprises a controller, a gating circuit, a locking piece (4) and an identification unlocking device (5) which are arranged on the shell (1), the gating circuit is electrically connected between the USB plug (2) and the USB interface (3), and the identification unlocking device (5) is electrically connected between the USB plug (2) and the USB interface (3). The control end of the controller is electrically connected with the control end of the gating circuit and controls the gating circuit to be switched on or switched off, so that the USB plug (2) and the USB interface (3) are correspondingly switched on or switched off, and the identification unlocking device (5) is electrically connected and communicated with the controller; through the shell, the USB plug on the shell, the USB interface, the controller, the gating circuit, the locking piece, the recognition unlocking device and the like, the safety of the USB interface is good.

Description

technical field [0001] The invention relates to the technical field of USB interface security, in particular to a USB interface isolation device. Background technique [0002] The power system computer is usually an intranet computer. Once the USB port of the computer is connected to an external network device, it will pose a serious threat to the security of the power system intranet network. [0003] The authorization announcement number is CN 206991321 U, and the name is USB interface isolation device. The solution is to solve the technical problem that the USB interface violates the rules and leads to the leakage of secrets. The technical solution adopted is that a base is connected to the tail of the plug, and the base is in a regular closed shape or an irregular closed shape; the surface of the base is provided with a marking part, and the surfaces of the base and the marking part are provided with coloring The surface of the base is provided with a light-emitting pa...
