Device for replacing block mode communication cable with shielding network cable

Abstract

The invention discloses a device for replacing a block mode communication cable with a shielding network cable. The device comprises a main communication device, an RJ45 female socket composition busconnecting plate and RJ45 female socket groups, the RJ45 female socket composition bus connecting plate is connected with the plurality of RJ45 female socket groups, and the RJ45 female socket composition bus connecting plate is also provided with a DC24V wiring terminal and a 485 wiring terminal; and the DC24V wiring terminal is connected with a DC24V bus which enters from the outside, and each network cable port is connected with a DC24V power supply circuit. Through the improvement of the application, potential safety hazards such as disconnection, disconnection and short circuit of cable connection in the construction process can be well solved, and the reliability is improved; and the faulty equipment can be directly taken away on line for maintenance or replacement without influencing the normal operation of other equipment.

Description

technical field [0001] The invention belongs to the field of communication connection, and in particular relates to a device using a shielded network cable instead of a modular communication cable. Background technique [0002] In the communication system, when the central control system is connected with the peripheral 485 communication equipment, it usually uses 2*1.5 power cable for power supply and 2*1.0 shielded twisted pair for communication, because there are always multiple peripheral 485 communication devices in a communication system. If the device is connected, then the power supply line and communication line (shielded twisted pair) must be connected in parallel from the first device to the second device, and then the second device is connected in parallel to the third device, and so on. There are many hidden dangers in practical applications. If the connection point of a certain device in the middle is loose or disconnected, the connection device before it will ...

[0002] In the communication system, when the central control system is connected with the peripheral 485 communication equipment, it usually uses 2*1.5 power cable for power supply and 2*1.0 shielded twisted pair for communication, because there are always multiple peripheral 485 communication devices in a communication system. If the device is connected, then the power supply line and communication line (shielded twisted pair) must be connected in parallel from the first device to the second device, and then the second device is connected in parallel to the third device, and so on. There are many hidden dangers in practical applications. If the connection point of a certain device in the middle is loose or disconnected, the connection device before it will lose its connection, or the wire burrs of the terminal will touch together due to the irregular wiring of the construction personnel and cause a short circuit. If the power interface is short-circuited, it will not only cause all equipment to fail, but also cause the power failure of the entire system; if the communication line interface is short-circuited, it will cause the entire communication data to fail, and in severe cases, the communication port will be damaged.
