Abstract
A network switching device belongs to the technical field of network switching, and solves the problem that the switching of the current communication between a computer user and different networks is inconvenient. The network switching device comprises a computer interface, two to sixteen network interfaces, and a physical switch. The computer interface is used for the connection with a computer of the user. The computer interface is connected with an input terminal of the physical switch. Two to sixteen output terminals of the physical switch are correspondingly connected with the two to sixteen network interfaces. The two to sixteen network interfaces are respectively used for the connection with different networks to be connected. The network switching device is suitable for the switching between the user and the multiple networks.
Description
Technical field
The utility model relates to network switching device, belongs to the network switch technical field.
Background technology
Often can run into such situation in local area network wiring, the two network interface cards of computer, one of them is the mainboard integrated network card, one is the network interface card of oneself adding up.Need to distinguish Connected Corp.'s finance net and corporate lan during due to office, each use all must be forbidden a network interface card just can enable another, very inconvenient.For will not distinguishing in the same time the user of communication with two above networks, it is more inconvenient to use.
Summary of the invention
The utility model is to have communication between computer user and heterogeneous networks now in order to solve, and the problem of being inconvenient to switch provides a kind of network switching device.
Network switching device described in the utility model, it comprises computer interfaceJi Suanjijiekou, a 2-16 network interface and physics switch,
Computer interfaceJi Suanjijiekou is used for being connected with user's computer, computer interfaceJi Suanjijiekou is connected with the input of physics switch, the 2-16 of a physics switch output and 2-16 network interface connect one to one, and 2-16 network interface is respectively used to connect from different networks to be connected.
Described physics switch is normally closed photoelectric isolating coupler.
Advantage of the present utility model: the utility model volume is little, can be placed on desk or on computer desk and use, the user just can realize and the automatic switchover of different networks to be connected as long as regulating corresponding switch controls, need not to restart computer during use, and saved the loaded down with trivial details of frequent plug netting twine, have and install simply, convenient to use, easy operating, the advantage that cost is low can guarantee the safety of data.
The utility model is physically switching due to what adopt, so internet security is high.The user can only be in IP of a network use at any time, and physically isolates fully between many nets.
Enforcement of the present utility model need not to load any software, there is no protocol requirement, and occupying system resources, can thoroughly not stop long-range malicious attack.
Description of drawings
Fig. 1 is the structured flowchart of network switching device described in the utility model.
Embodiment
Embodiment one: below in conjunction with Fig. 1, present embodiment is described, the described network switching device of present embodiment, it comprises computer interfaceJi Suanjijiekou 1, a 2-16 network interface 2 and physics switch 3,
Present embodiment can be used for realizing the switching back and forth between Intranet, as the switching debugging between training subnet, financial subnet, occurrences in human life subnet.Also can be applicable to switch between wide area network and internal lan, realize physical isolation completely.The user can only be on a network at any time, and physically isolates fully between this network and other net, switches contacting of maintenance user and Intranet or outer net by physics.
Described network switching device can adopt metal shell, has USB Power supply interface, can be with the connection corresponding with output port of any one input interface at physics switch 3 inner utilization matrix switches.2-16 network interface 2 is the RJ45 type network port.Can adopt LED to show the switching state at physics switch 3 places, described network switching device can be arranged between a plurality of networks, with the straight through cable connection, also near the user terminal place.
The enforcement of present embodiment does not need power supply, to network signal without the interference on electricity.
Embodiment two: present embodiment is for to the further illustrating of execution mode one, and the described physics switch 3 of present embodiment is normally closed photoelectric isolating coupler.
The utility model has greatly improved the network security coefficient, can simply realize the switching between many nets, avoids hardware repeatedly to plug the damage that machine and circuit are caused.
