Description

Technical Field

[0001] This utility model relates to the technical field of network cable mis-plugging prevention devices, specifically a network cable mis-plugging prevention device. Background Technology

[0002] Network cables are used to build computer networks and enable data transmission between network devices. They are a key physical medium in network communication systems. The core function of a network cable is to establish a data transmission channel for various devices in the network (such as computers, servers, switches, and routers), allowing different devices to send and receive digital signals, thereby enabling various network applications such as file sharing, web browsing, video calls, and online games. Common types include: Ethernet cables (twisted pair): This is the most common type of network cable, consisting of multiple pairs of twisted copper conductors wrapped in an insulating sheath. Its twisting design aims to reduce the impact of electromagnetic interference on signal transmission; Fiber optic cables: mainly composed of a fiber core, cladding, and coating; Coaxial cables: structurally consisting of an inner conductor, insulation layer, outer conductor (shielding layer), and sheath.

[0003] However, some existing network cables do not have anti-misplugging structures, which may not only lead to frequent network failures and damage to network equipment, but also increase the difficulty and cost of network maintenance, and affect network security and data integrity.

[0004] Therefore, those skilled in the art have provided a network cable anti-misinsertion device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a network cable anti-misplugging device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A network cable anti-misplugging device includes an external socket; a module fixing frame is fixedly connected to the upper middle of the external socket, and a control circuit module is fixedly connected inside the module fixing frame; a slot is cut into the rear side of the outer surface of the external socket, and a plurality of first insulating cavities are provided inside the slots, and a plurality of metal springs are fixedly connected inside the first insulating cavities; lamp tube fixing rods are fixedly connected to the left and right sides of the external socket, and a warning light is fixedly connected to the rear side of the lamp tube fixing rods; a network cable plug is provided inside the external socket, and a second insulating cavity is cut into the left and right sides of the outer surface of the network cable plug, and a plurality of metal pins are fixedly connected inside the second insulating cavity.

[0008] As a further embodiment of this invention, a buckle is provided on the upper side of the network cable plug.

[0009] As a further embodiment of this utility model, a plug connector block is fixedly connected to the rear side of the network cable plug.

[0011] As a further embodiment of this utility model, a connecting bracket is fixedly connected to the rear side of the plug connecting block.

[0012] As a further embodiment of this utility model, a network connection cable is fixedly connected to the rear side of the connecting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Warning lights can indicate whether network cable plugs have been misconnected. In complex network environments, such as large enterprise offices and data centers, there are numerous network cables with different functions and routes. Misconnection can cause a cable intended for a specific server or switch port to be plugged into the wrong location, leading to network link interruptions or malfunctions. Anti-misconnection network cables ensure that each cable is accurately connected to its corresponding port, maintaining the correctness of the network topology and guaranteeing smooth data transmission along the planned path. This significantly reduces network failures caused by incorrect cable connections, ensuring stable and reliable network communication. Furthermore, various ports on network devices have specific electrical parameters and signal standard requirements. For example, some ports are designed for high-speed Ethernet signals with relatively fixed input voltage and current ranges. When a cable is misconnected to an incompatible port, it may introduce unsuitable electrical signals, potentially causing short circuits, chip burnout, and other damage to the device. By implementing anti-misplugging measures, physical damage to network equipment caused by incorrect connections can be effectively avoided, extending the equipment's lifespan and reducing the company's costs for network equipment maintenance and replacement. Furthermore, in routine network maintenance, equipment replacement, and new user access scenarios, operators may misplug network cables due to negligence or unfamiliarity with the wiring. Anti-misplugging devices use physical structural restrictions and signal recognition to alert or prevent misplugging, reducing the probability of network problems caused by human error and improving the accuracy and standardization of network-related operations.

Detailed Implementation

[0020] Please see Figures 1-4 In this embodiment of the utility model, a network cable anti-misplugging device includes an external socket 1; a module fixing frame 2 is fixedly connected to the upper middle of the external socket 1, and a control circuit module 3 is fixedly connected inside the module fixing frame 2; a slot 4 is slotted inside the rear side of the outer surface of the external socket 1, and a plurality of first insulating cavities 5 are provided inside the slot 4, and a plurality of metal springs 6 are fixedly connected inside the first insulating cavities 5; lamp tube fixing rods 7 are fixedly connected to the left and right sides of the external socket 1, and a warning light 8 is fixedly connected to the rear side of the lamp tube fixing rod 7; the... The external socket 1 has a network cable plug 9 inside. The outer surface of the network cable plug 9 has slots on the left and right sides to form a second insulating cavity 10. Several metal pins 11 are fixedly connected inside the second insulating cavity 10. The upper side of the network cable plug 9 has a buckle 12. The rear side of the network cable plug 9 is fixedly connected to a plug connecting block 13. The upper side of the plug connecting block 13 has a buckle pressing piece 14. The rear side of the plug connecting block 13 is fixedly connected to a connecting fixing bracket 15. The rear side of the connecting fixing bracket 15 is fixedly connected to a network connecting cable 16.

[0021] The working principle of this utility model is as follows: In use, the control circuit module 3 is first installed and fixed inside the module mounting bracket 2. Following the standard circuit design requirements, the power supply line of the control circuit module 3 and the signal lines of other related parts are connected to ensure normal operation and to receive and process corresponding signals. Then, the metal spring 6 is installed into the first insulating cavity 5, located within the external socket 1. It is crucial to ensure that the metal spring 6 is precisely positioned so that it accurately contacts the corresponding metal pin 11 when the network cable plug 9 is inserted. Furthermore, the metal spring 6 should fit well against the inner wall of the first insulating cavity 5 to provide insulation and prevent short circuits or other abnormalities. Then, the control circuit module 3 is debugged in its initial state without the network cable plug 9 inserted. Use a multimeter or similar tools to test the voltage, resistance, and other parameters of the relevant circuit nodes to ensure that the control circuit module 3 is in a normal standby state. For example, its internal signal processing unit, comparator, and other circuit components are working properly. At this time, the warning light 8 should be off (or, as designed, in a specific state indicating that it is not connected). Then, slowly insert the network cable plug 9 into the slot 4 of the external socket 1. During the insertion process, the metal pins 11 on the network cable plug 9 will gradually approach the metal spring 6 in the first insulating cavity 5 of the external socket 1. When the network cable plug 9 is fully inserted into the correct position, the metal pins 11 and the metal spring 6 will make contact one by one, forming a complete physical connection. As the network cable plug 9 is inserted into the correct position, the latch 12 of the network cable plug 9 will... The network cable plug 9 is automatically locked by the internal structure of slot 4. The latching pressing piece 14 assists in locking the latch 12 and facilitates subsequent unlocking and removal, ensuring a secure connection between the network cable plug 9 and the external socket 1, preventing accidental dislodgement during normal use, and guaranteeing the stability of the network connection. Then, the control circuit module 3 monitors the circuit status after the metal pin 11 and metal spring 6 are connected in real time. It determines whether the network cable plug 9 is correctly inserted by detecting whether current flows through the circuit and whether the node voltage reaches the set threshold. If the network cable plug 9 matches the external socket 1, that is, it is correctly inserted, the control circuit module 3 detects that the circuit is normally connected, and outputs the corresponding control signal to the warning light according to the internal preset logic. If an incorrect network cable connector 9 is inserted into the connection line 8 (e.g., mismatched type, incorrect pin layout, etc.), the metal pins 11 and the metal spring contact 6 cannot make proper and complete contact to form a valid circuit. The control circuit module 3 detects that the circuit is still open and will process it according to a different preset logic. When the network cable connector 9 is correctly inserted, the control circuit module 3 outputs a valid control signal to drive the warning light 8 to illuminate in a preset color indicating a correct connection, visually informing the operator that the network cable connection is accurate and there is no misinsertion. Conversely, if it is misinserted, the warning light 8 will illuminate in a preset color indicating an incorrect connection or will not illuminate, indicating to the operator that there is a misinsertion and the network cable connector 9 needs to be re-checked and correctly inserted.This prevents the network cable plug 9 from being mis-plugged. The warning light 8 indicates whether the network cable plug 9 has been mis-plugged. In complex network environments, such as large enterprise offices and data centers, there are numerous network connection cables 16 with different functions and routes. If mis-plugging occurs, the network cable that should be connected to a specific server or switch port may be plugged into the wrong position, leading to network link interruption or abnormality. The network cable mis-plugging protection ensures that each network cable is accurately connected to the corresponding port, maintaining the correctness of the network topology and ensuring that data can be transmitted smoothly according to the planned path. This greatly reduces network failures caused by incorrect network cable connections, keeping network communication stable and reliable. Moreover, various ports of network devices have their own compatible electrical parameters and signal standard requirements. For example, some ports are used to transmit high-speed Ethernet signals, and their designed input voltage and current ranges are relatively fixed. When a network cable is mis-plugged into an incompatible port, it may introduce an unsuitable electrical signal, causing damage such as short circuits or chip burnout inside the device. By implementing anti-misplugging measures, physical damage to network equipment caused by incorrect connections can be effectively avoided, extending equipment lifespan and reducing enterprise costs for network equipment maintenance and replacement. Furthermore, in routine network maintenance, equipment replacement, and new user access scenarios, operators may mistakenly plug network cables in due to negligence or unfamiliarity with the wiring. Anti-misplugging devices use physical structural limitations and signal recognition to alert or prevent such misplugging, reducing the probability of network problems caused by human error and improving the accuracy and standardization of network-related operations.
