Description

Technical Field

[0001] This utility model relates to the field of communication equipment testing technology, specifically to a switch network testing device. Background Technology

[0002] Switches typically communicate with upstream routers using eight-core shielded twisted-pair cables. When communication problems or interruptions occur, it's generally necessary to first check the continuity of the twisted-pair cable before testing the switch itself. Existing network testing equipment for link-layer switches, in order to ensure multi-functionality for comprehensive testing, generally has complex internal control module configurations and printed circuit designs, resulting in high equipment costs, susceptibility to failure, large size, and inconvenience in portability. Since twisted-pair continuity failures account for a very high percentage of communication failures in link-layer switches, and switch failures can be predicted by consulting on-site users, there is a need for a testing device that can effectively troubleshoot twisted-pair faults and possesses good portability and practicality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a network testing device for a switch, which can effectively test the continuity and wiring sequence of the upstream and downstream eight-core and shielded twisted-pair cables of the switch. At the same time, while ensuring the functionality, the control board is designed to be extremely simple, so that it has the advantages of simple structure, low cost and easy portability.

[0004] This network testing device for a switch includes a host unit for connecting to the upstream end of the twisted-pair cable under test and a slave unit for connecting to the downstream end of the twisted-pair cable under test. The host unit's control board integrates a pulse source module, nine main LEDs, nine main protection LEDs, an RJ45 main network port module, a switch module, and a power supply module. The output of the pulse source module is connected to the RJ45 main network port module via the nine main LEDs. The nine main protection LEDs are connected in parallel to the nine main LEDs. The power supply module is connected to the pulse source module via the switch module. The slave unit's control board integrates nine secondary LEDs, nine secondary protection LEDs, and an RJ45 secondary network port module. The RJ45 secondary network port module is connected to the nine secondary LEDs, and the nine secondary protection LEDs are connected in parallel to the nine secondary LEDs.

[0005] Furthermore, the main unit housing has a card slot on its side and a button switch on its front. The network port of the main network port module and the main light-emitting diode are exposed on the structural slots opened on the top and front of the main unit housing. The secondary unit housing has a T-shaped card ridge that matches the card slot. The secondary network port module and the secondary protection diode are exposed on the structural slots opened on the top and front of the secondary unit housing.

[0006] Specifically, the pulse source module uses an NE555 oscillator chip.

[0007] Specifically, the pulse source module uses a 4017 counter chip.

[0008] Specifically, both the main protection diode and the secondary protection diode are 1N4148 diodes.

[0009] This utility model discloses a network testing device for switches, which can effectively test the continuity and wiring sequence of upstream and downstream eight-core and shielded twisted-pair cables of switches. At the same time, while ensuring the functionality, the control board is designed with extreme simplicity, so that it has the advantages of simple structure, low cost and easy portability.

[0019] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0020] Implementation method 1: such as Figures 1 to 3 As shown, the system includes a main unit 1 for connecting to the upstream end of the twisted pair cable under test and a secondary unit 2 for connecting to the downstream end of the twisted pair cable under test. The main unit 1 has a control board integrating a pulse source module 11, nine main LEDs 12, nine main protection LEDs 13, an RJ45 main network port module 14, a switch module 15, and a power module 16. The output of the pulse source module 11 is connected to the RJ45 main network port module 14 via the nine main LEDs 12. The nine main protection LEDs 13 are connected in parallel to the nine main LEDs 12. The power module 16 is connected to the pulse source module 11 via the switch module 15. The secondary unit 2 has a control board integrating nine secondary LEDs 21, nine secondary protection LEDs 22, and an RJ45 secondary network port module 23. The RJ45 secondary network port module 23 is connected to the nine secondary LEDs 21, and the nine secondary protection LEDs 22 are connected in parallel to the nine secondary LEDs 21.

[0021] Implementation method 2: such as Figure 1 , 2 As shown, the host 1 of this switch network detection device has a card slot 101 on its side and a push-button switch 102 on its front. The network port of the main network port module 14 and the main light-emitting diode 12 are exposed in the structural slots on the top and front of the host 1's housing. The secondary unit 2 has a T-shaped card ridge 201 that matches the card slot. The secondary network port module 23 and the secondary protection diode 22 are exposed in the structural slots on the top and front of the secondary unit 2's housing. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0022] Implementation Method 3: This switch network detection device: The pulse source module 11 uses an NE555 oscillator chip to generate oscillation pulses. The main protection diode 13 and the secondary protection diode 22 both use 1N4148 diodes for unidirectional conduction isolation and overcurrent / overvoltage protection of the LEDs. The remaining structures and components are as described in Implementation Method 1 and will not be repeated.

[0023] Implementation Method 4: The pulse source module 11 of this switch network detection device uses a 4017 counter chip to generate decimal digital pulses. The remaining structure and components are as described in Implementation Method 1 and will not be repeated.

[0024] In use: Connect the twisted pair cable to be tested to the network port exposed on the main and auxiliary unit's network port module. Press the switch on the main unit's housing to activate the main control board's switch module, which will then generate a sequence of pulses. The main LED on the main unit and the auxiliary LED on the auxiliary unit will light up sequentially. If the LED on the auxiliary unit does not light up, the wire number corresponding to that LED is considered to be disconnected. If the LED lighting sequence on the auxiliary unit does not correspond to that on the main unit, it is considered to be a wiring sequence fault. If the LED on the main unit does not light up, it is considered to be a connector fault.

[0025] This network testing device for switches can effectively test the continuity and wiring sequence of eight-core and shielded twisted-pair cables upstream and downstream of the switch. At the same time, while ensuring the functionality, the control board is designed with minimalism, making it simple in structure, low in cost, and easy to carry.
