Description

Technical Field

[0001] This utility model relates to the field of communication network maintenance technology, and in particular to a network switch based on physical isolation. Background Technology

[0002] As is well known, 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 work on information systems and bearer networks, the common practice is to repeatedly plug and unplug network patch cords between multiple isolated switches to connect the maintenance equipment to different functional networks. Switching networks using patch cords 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. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a network switch based on physical isolation, which realizes a network switching environment that is reliable, easy to operate and convenient to use.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A network switch based on physical isolation includes a carrier housing, a switching rotary switch and a switching connector. A rotating central shaft supported by a fixing frame is provided along the length direction of the carrier housing and located at its internal center. Multiple sets of switching rotary switches are evenly fixed along the length direction of the rotating central shaft, and each set of switching rotary switches corresponds to a switching connector.

[0006] The on / off connector has a trapezoidal slot at intervals, and a copper spring is fixed in each trapezoidal slot. Each set of switching rotary switches includes a switch piece, which is located in the eight trapezoidal slots on the corresponding on / off connector. The eight switches of the rightmost switching rotary switch have multiple hemispherical copper contacts evenly spaced on them. The eight switches of the other sets of switching rotary switches each have a hemispherical copper contact. The copper contacts match the copper springs on the on / off connector. The on / off connector is connected to multiple RJ45 network interfaces on the carrier housing.

[0007] The network switch based on physical isolation has a number of copper contacts on the rightmost rotary switch that is equal to the sum of the number of the other rotary switches. The rightmost rotary switch is connected to the corresponding sections of the other rotary switches via wires. Each copper contact on the rightmost switch corresponds to each copper contact on the other rotary switches.

[0008] The aforementioned network switch based on physical isolation has two fixing frames, which are fixed to the inside of the bearing housing on both sides. A circular seat is provided at the upper end of the fixing frame, and a bearing connected to the rotating central shaft is provided in the circular seat.

[0009] The aforementioned physical isolation-based network switch has multiple RJ45 network interfaces evenly spaced and fixed on the rear panel of the supporting housing for connecting multiple isolated networks. The RJ45 network interface located at the rightmost end is used to connect network or information system maintenance equipment.

[0010] The network switch based on physical isolation has the same number of on / off connectors as the number of RJ45 network interfaces. Each RJ45 network interface is equipped with network cables numbered 1-8. The copper springs in each on / off connector correspond to and are connected to network cables numbered 1-8 of multiple RJ45 network interfaces.

[0011] The aforementioned network switch based on physical isolation has a square-shaped housing with longitudinal and transverse reinforcing ribs inside. A circular hole is provided in the middle of one side of the housing. One end of the rotating shaft extends out of the housing and is fixedly connected to the manual switching knob. Rotation markings for switch a, switch b... switch n are evenly distributed along the circumference of the manual switching knob, and the number of markings is the same as the number of copper contacts on the rightmost switching switch plate.

[0012] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0013] The network switch based on physical isolation described in this utility model achieves rapid, accurate, and intuitive switching between different networks when the copper spring on the switching switch on the rotating shaft contacts the copper spring on the on / off connector by turning the manual switching knob. This utility model has a simple structure, reliable performance, and easy operation. It achieves switching between different networks without affecting the network isolation status, reduces the risk of cross-network connections, simplifies network maintenance, and improves the efficiency of information system maintenance.

Rotation marks of network gate a, network gate b... network gate 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 rightmost switching rotary switch 4 plate 9.

[0022] Furthermore, the number of copper contacts 8 on the rightmost rotary switch 4 is equal to the sum of the number of the other rotary switches 4, and the rightmost rotary switch 4 is connected to the corresponding sections of the other rotary switch 4 via wires.

The rightmost RJ45 network interface is used to connect to network or information system maintenance equipment, while the other four RJ45 network interfaces are used to connect four isolated networks. The manual switching knob 1 has four positions: gateway a, gateway b, gateway c, and gateway d. Five sets of rotary switching switches 4 are provided. From the first to the fourth set on the left, the copper contacts 8 on the rotary switching switches are arranged at 90-degree intervals in a clockwise or counterclockwise direction.
