In order to achieve the purpose, the invention adopts the technical scheme that: a network safety connection kit is characterized by comprising a safety joint and a safety shell which can be fixed on a network interface, wherein the safety joint comprises a joint pin module and a telescopic device used for changing the width of the safety joint, the telescopic device comprises a spring element, a first sliding part and a second sliding part, the safety shell comprises a first limiting plate with a first sliding groove, a second limiting plate with a second sliding groove, a third limiting plate respectively connected with the first limiting plate and the second limiting plate, a first blocking part connected with the first limiting plate and a second blocking part connected with the second limiting plate, the depth of the first sliding groove is gradually increased from the rear end of the first limiting plate to the front end of the first limiting plate, the depth of the second sliding groove is also gradually increased from the rear end of the second limiting plate to the front end of the second limiting plate, first slider can stretch into first sliding tray, the second slider can stretch into the second sliding tray, first stop piece and second stop piece can both stretch into the accommodation space of network interface, the distance between the outside surface of first limiting plate and the outside surface of second limiting plate is greater than the width of the accommodation space of network interface, safety joint's maximum width is greater than the width of the accommodation space of network interface and is less than the maximum depth of first sliding tray, the maximum depth of second sliding tray and the sum of the distance between first limiting plate and the second limiting plate, safety joint's minimum width is not more than the width of the accommodation space of network interface.

In the technical scheme of the invention, the width of the safety joint can be adjusted through the telescopic device, and the width of the safety joint can be changed from the minimum width to the maximum width. When the safety joint is inserted into the network interface provided with the safety shell from the outside, the telescopic device is compressed in the process of contacting with the first limiting plate and the second limiting plate, so that the width of the safety joint is gradually reduced, the safety joint can extend into the accommodating space of the network interface, and the electric connection with the network interface is realized; for the network interface without the safety shell, when the safety joint is inserted into the network interface from the outside, the expansion device of the safety joint is not acted by the acting force of the safety shell to reduce the width of the safety joint, and the width of the safety joint without the reduced width is larger than the width of the network interface accommodating space, so that the safety joint cannot be inserted into the network interface without the safety shell and is electrically connected.

Because the safety shell can be fixed on the network interface of the computer used on the confidential network such as the public security network, the standard network joint arranged on the connecting end of the network cable connected to the Internet can be prevented from being inserted into the accommodating space of the network interface to realize the electric connection with the network interface, thereby being beneficial to preventing the computer connected on the confidential network such as the public security network from generating a security divulgence event; in addition, the security connector of the present invention can be used as a dedicated network connector for connecting the network lines of a secure network such as a public security network, and can be electrically connected to the network interface of a computer used in the secure network such as a public security network provided with a security housing, but cannot be electrically connected to the network interface of a computer on the internet not provided with a security housing, thereby preventing leakage of secure information.

Preferably, the distance between the first limiting plate and the second limiting plate is equal to the width of the accommodating space of the network interface. Generally, the depth of the first sliding groove gradually increases from 0 to a maximum value from the rear end of the first stopper plate to the front end of the first stopper plate, and the depth of the second sliding groove gradually increases from 0 to a maximum value from the rear end of the second stopper plate to the front end of the second stopper plate. The maximum depth of the first sliding groove and the maximum depth of the second sliding groove are preferably both between 1.5 mm and 2.5 mm.
