Technical Field

The invention relates to the technical field of communication, in particular to a network security connection suite.

Background

In the prior art, a computer is connected to the internet, sometimes it is necessary to connect with a network interface on the computer through a network cable, wherein a network connector is arranged at a connection end of the network cable, and the communication between the computer and the internet can be realized by connecting the network connector and the network interface in a matching manner.

At present, the RJ45 standard is commonly used for network interfaces of computers connected to a secure network such as a public security network, and the RJ45 standard is also commonly used for a network connector provided at a connection terminal of a network cable connected to the internet and a network connector provided at a connection terminal of a network cable connected to a secure network such as a public security network, so that a standard network connector provided at a connection terminal of a network cable connected to the internet is easily mistakenly connected to a network interface of a computer used on a secure network such as a public security network, and similarly, a standard network connector provided at a connection terminal of a network cable connected to a public security network is also easily mistakenly connected to a network interface of a computer used on the internet, and leakage of secure information is easily caused by these erroneous connections. Therefore, how to prevent the misconnection between the secure network such as the public security network and the internet and the network connector through the network interface is a technical problem to be solved.

Disclosure of Invention

The invention aims to provide a network security connection kit, which is used for preventing a computer used on a secret network such as a public security network or the like from being wrongly connected with the Internet or a computer used on the Internet, so as to ensure the security of the secret network such as the public security network and the like.

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 capable of being fixed on a network interface, wherein the safety joint comprises a joint pin module and a telescopic device for changing the width of the safety joint, the safety shell comprises a first limiting plate and a second limiting plate which are arranged at a certain distance, a third limiting plate and a fourth limiting plate which are arranged at a certain distance in parallel, and a fifth limiting plate which is respectively connected with the first limiting plate and the second limiting plate, the rear end of the first limiting plate is connected with the third limiting plate, the rear end of the second limiting plate is connected with the fourth limiting plate, the first limiting plate and the second limiting plate are respectively positioned at two sides of the axis of the symmetry shaft of the safety shell, the third limiting plate and the fourth limiting plate are respectively positioned at two sides of the axis of the symmetry shaft of the safety shell, and the first limiting plate is gradually far away from the axis from the rear end of the first limiting plate to the front end of the first limiting plate, the second limiting plate is gradually far away from the axis from the rear end of the second limiting plate to the front end of the second limiting plate, the third limiting plate and the fourth limiting plate can stretch into the accommodating space of the network interface, the distance between the outer side surface of the first limiting plate and the outer side surface of the second limiting plate is larger than the width of the accommodating space of the network interface, the maximum width of the safety joint is larger than the width of the accommodating space of the network interface and smaller than the distance between the front end of the first limiting plate and the front end of the second limiting plate, and the minimum width of the safety joint is not larger than the distance between the third limiting plate and the fourth limiting plate.

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 a space between the third limiting plate and the fourth limiting plate, and the electric connection with the network interface provided with the safety shell 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 be electrically connected with the network interface, and the safety shell is favorable for preventing the computer connected on the confidential network such as the public security network from generating a security divulging 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 telescopic device comprises a spring element, a first slide and a second slide.

In a preferred embodiment, the safety joint includes a connection housing defining and protecting the joint pin module, the retractor being connected to the connection housing. In another preferred embodiment, the safety joint includes a connection housing defining and protecting the joint pin module, the connection housing including a slide that can accommodate the first slide and the second slide for sliding movement.

In the present embodiment, the distance D11 between the front end 21 of the first stopper plate 3 and the front end 31 of the second stopper plate 4 is 16 mm; the distance between the rear end 22 of the first limit plate 3 and the rear end 32 of the second limit plate 4 is equal to the distance D3 between the third limit plate 13 and the fourth limit plate 14, which is 10.5 mm; the length D8 of the third flat plate 13 is equal to the length of the fourth flat plate 14, which is 6 mm; the height D7 of the third flat panel 13 is equal to the height of the fourth flat panel 14, which is 6.5 mm.

The network interface 6 shown in fig. 4 is a network interface adopting RJ45 standard, and the network interface provided on the computer generally adopts a network interface adopting RJ45 standard. In this embodiment, the maximum width D5 of the safety joint 2 is 13.5 mm, the minimum width D6 of the safety joint 2 is 10.3 mm, the width D1 and the minimum height D2 of the accommodating space 7 of the network interface 6 are about 11.8 mm and about 6.9 mm, respectively, the distance D10 between the outer side surface of the first limiting plate 3 and the outer side surface of the second limiting plate is 14 mm, and since the distance D10 is greater than the width D1 of the accommodating space 7 of the network interface 6, the first limiting plate 3 and the second limiting plate 4 of the safety housing 1 cannot extend into the accommodating space 7 of the network interface 6.

In the present embodiment, the safety joint 2 includes a joint pin module 8, a connection housing 9 defining and protecting the joint pin module 8, a clip 10, and a telescopic device 12 for changing a width of the safety joint, a maximum width D5 of the safety joint is smaller than a distance D11 between a front end 21 of the first stopper plate 3 and a front end 31 of the second stopper plate 4, a maximum width D5 of the safety joint is larger than a width D1 of an accommodating space of the network interface 6, a minimum width D6 of the safety joint 2 is smaller than a distance D3 between the third stopper plate 13 and the fourth stopper plate 14, a height D7 and a width D9 of an outer peripheral dimension formed by the third plate 13 and the fourth plate 14 of the safety housing 1 are 6.5 mm and 11.5 mm, respectively, the minimum height D2 and the width D1 of the accommodating space 7 of the network interface 6 are about 6.9 mm and about 11.8 mm respectively, thus, both the third plate 13 and the fourth plate 14 of the safety housing 1 can project into the receiving space 7 of the network interface 6.

The spring element 17 is thus able to expand and contract under the action of external force, so that the positions of the first slider 121 and the second slider 122 are moved, thereby adjusting the width of the safety joint 2, and the width of the safety joint 2 is changed between the maximum width D5 and the minimum width D6.

When the safety joint 2 is inserted into the network interface 6 provided with the safety shell 1 from the outside, the telescopic device 12 is compressed when the first limiting plate 3 and the second limiting plate 4 are in contact with each other, so that the width of the safety joint 2 is gradually reduced, and the safety joint can extend into a space between the third limiting plate 13 and the fourth limiting plate 14 to be electrically connected with the network interface 6; for the network interface 6 without the safety housing 1, when the safety connector 2 is inserted into the network interface 6 from the outside, the telescopic device 12 of the safety connector is not subjected to the acting force of the safety housing 1 to reduce the width of the safety connector 2, and the safety connector without the reduced width is in the state of the maximum width D5, and the maximum width D5 is greater than the width D1 of the accommodating space 7 of the network interface 6, so that the safety connector 2 cannot be inserted into the network interface without the safety housing and is electrically connected.
