Technical field

The invention belongs to communication connection fields, and in particular to a kind of dress for replacing block mould communication cable using shielding netting wire It sets.

Background technique

In communication system, when central control system and peripheral 485 communication apparatus are attached, 2*1.5 electricity is generallyd use Source cable power supply and 2*1.0 Shielded Twisted Pair are communicated, due to always there is the more communications of periphery 485 to set in a set of communication system Standby access, then power supply power supply line and connection (Shielded Twisted Pair) will be parallel to from first equipment second equipment again by Second equipment parallel connection third equipment and so on, but there are many hidden danger in practical applications in above-mentioned connection method, such as Some equipment tie point among fruit is loosened or is disconnected, then the connection equipment before it can all disconnect, or due to Construction personnel's wiring conducting wire burr lack of standardization for making connecting terminal touches causes short circuit together, not only if it is power interface short circuit It can make armamentarium failure that can also cause whole system power failure；It will lead to entire communication number if it is communication line interface short circuit According to failure, communication port is damaged when serious.In conclusion so I devises a kind of use shielding netting wire substitution block mould communication cable Device.

Summary of the invention

To solve the above problems, the present invention provides a kind of dress for replacing block mould communication cable using shielding netting wire It sets.

The present invention is achieved through the following technical solutions:

A kind of device replacing block mould communication cable using shielding netting wire, including main communication apparatus, RJ45 base composition are total Line connecting plate and RJ45 base group, the RJ45 base form and are connected with several RJ45 bases on bus connecting plate Group: and RJ45 base composition bus connecting plate is additionally provided with DC24V connecting terminal and 485 connecting terminals；The DC24V The DC24V bus from outer entrance is connected on connecting terminal, and each cable mouth is connect with DC24V power circuit；Described 485 connect Be connected to 485 buses from outer entrance in line terminals, and each cable mouth with 485 connections；The main communication apparatus DC24V power end is connected with the DC24V connecting terminal of RJ45 base composition bus connecting plate；485 ends of the main communication apparatus It is connected with 485 connecting terminals of RJ45 base composition bus connecting plate.
