Description

Technical Field

[0001] The present invention relates to the technical field of communication network maintenance, and in particular to a network switch based on physical isolation and a method for using the same. Background Art

[0002] It is well known that due to the nature of the industry and the needs of information network construction and maintenance, many information networks require logical isolation or even physical isolation. When performing maintenance operations on information systems and bearer networks, a common practice is to use network jumpers to repeatedly plug and unplug multiple switches that are isolated from each other to achieve the connection between maintenance equipment and different functional networks. Using jumpers to switch networks is not only cumbersome, time-consuming and labor-intensive, but also prone to errors, which seriously affects the efficiency and effectiveness of information system maintenance. Summary of the invention

[0003] In order to overcome the deficiencies in the background technology, the present invention discloses a network switch based on physical isolation and a method for using the same, so as to achieve a network switching environment with reliable performance, simple operation and convenient use.

[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme: A network switch based on physical isolation, comprising a bearing shell, a switching rotary switch and an on-off connector, wherein a rotating central axis supported by a fixing frame is provided along the length direction of the bearing shell and at the inner center thereof, and a plurality of groups of switching rotary switches are fixed at even intervals along the length direction of the rotating central axis, and each group of switching rotary switches corresponds to an on-off connector; Trapezoidal slots are arranged at intervals on the on-off connector, and a copper spring is fixed in each of the trapezoidal slots. Any set of switching rotary blades includes a gate, which are respectively located in the 8 trapezoidal slots on the corresponding on-off connector. A plurality of hemispherical copper contacts are evenly spaced on the 8 gates of the rightmost switching rotary blade, and a hemispherical copper contact is provided on each of the 8 gates of the remaining sets of switching rotary blades. The copper contacts are matched with the copper springs on the on-off connectors, and the on-off connectors are respectively connected to a plurality of RJ45 network interfaces on the carrier shell.

[0005] In the network switch based on physical isolation, the number of copper contacts arranged on the gate piece of the rightmost switching rotary switch is equal to the sum of the number of the remaining switching rotary switches, and the rightmost switching rotary switch is respectively connected to the corresponding intervals of the gate pieces of the remaining multiple switching rotary switches through wires, and each copper contact arranged on the rightmost gate piece corresponds to each copper contact of the gate pieces of the remaining switching rotary switches.

[0006] The network switch based on physical isolation has two fixing frames which are respectively fixed on both sides of the interior of the bearing shell. An annular seat is provided at the upper end of the fixing frame, and bearings connected to the rotating central axis are provided in the annular seat.

[0007] The network switch based on physical isolation has multiple RJ45 network interfaces evenly fixed on the rear side panel of the bearing shell for connecting multiple isolated networks. The RJ45 network interface at the far right is used for connecting the network or information system maintenance equipment.

[0008] The network switch based on physical isolation has the same number of on-off connectors as the number of RJ45 network interfaces. Any RJ45 network interface is provided with No. 1-8 network cables. The copper spring in each on-off connector corresponds to and is connected to No. 1-8 network cables of multiple RJ45 network interfaces.

[0009] The network switch based on physical isolation is characterized in that the bearing shell is arranged in a square shape, and longitudinal and transverse reinforcing ribs are arranged inside it. A circular hole is opened in the middle of one side surface of the bearing shell, and one end of the rotating central axis extends out of the bearing shell and is fixedly connected to the manual switching knob. Rotating marks of network switches a, network switches b...network switches n are evenly distributed along the circumferential direction of the manual switching knob, and the number of marks is the same as the number of copper contacts on the rightmost switching rotary switch blade.

[0010] A method for using a network switch based on physical isolation specifically comprises the following steps: S1. Insert network cables connected to external computers into multiple RJ45 network interfaces on the carrier housing; S2. Manually rotate the manual switch knob to the rotation mark of network gate a. During the rotation process, the manual switch knob drives the rotating center axis to rotate, and the copper contacts on the switch rotating knife blade corresponding to network gate a contact with the copper reed in the on-off connector, thereby connecting the input and output networks at network gate a. At this time, the copper contacts on other blades are not in contact with the corresponding copper reeds, thereby disconnecting the input and output networks at other network gates; S3, manually rotate the manual switch knob to the rotation mark of network gate b, and the manual switch knob drives the rotating central axis to rotate, so that the copper contact on the switch rotary knife gate piece corresponding to network gate b contacts the copper reed in the on-off connector, so as to realize the connection between the input and output end networks at network gate b. At this time, the copper contacts on other gate pieces are not in contact with their corresponding copper reeds, so as to realize the disconnection between the input and output end networks at other network gates; S4. Taking the above steps as an example, if you need to turn on a certain network, you only need to rotate the manual switch knob to the corresponding network switch mark. Only one network can be turned on at a time. The copper contact on the rightmost switching rotary switch blade is always in contact with the copper spring in the corresponding on-off connector.

[0011] Due to the adoption of the above technical solution, the present invention has the following beneficial effects: The network switch based on physical isolation and the method of using the same described in the present invention realize fast, accurate and intuitive switching of different networks by twisting a manual switching knob to drive the rotating central axis to rotate, and when the copper reed on the switching rotating switch on the rotating central axis contacts the copper reed on the on-off connector; the present invention has a simple structure, reliable performance and easy operation, and can realize switching of different networks without affecting the isolation state of the network, thereby reducing the risk of cross-network connection of different networks, alleviating the difficulty of network maintenance and improving the efficiency of information system maintenance.

Rotating marks of network gates a, network gates b...network gates n are evenly distributed in the circumferential direction of the manual switching knob 1, and the number of marks is the same as the number of copper contacts 8 on the gate piece 9 of the switching rotating knife 4 located on the rightmost side.

[0019] Furthermore, the number of copper contacts 8 arranged on the gate piece 9 of the rightmost switching rotary knife 4 is equal to the sum of the number of the remaining switching rotary knives 4, and the rightmost switching rotary knife 4 is respectively connected to the corresponding intervals of the gate pieces 9 of the remaining multiple switching rotary knives 4 through wires, and each copper contact 8 set on the rightmost gate piece 9 corresponds to each copper contact 8 of the gate pieces 9 of the remaining switching rotary knives 4.

[0020] Furthermore, multiple RJ45 network interfaces are evenly spaced and fixed on the rear side panel of the carrying shell 2, and are used to connect multiple isolated networks.
