Utility model content
In view of this, the purpose of this utility model is to provide a kind of RS-485 order wire connecting terminal box, arranges that great in constructing amount and thunderbolt destroys the problem of RS-485 communication to solve RS-485 order wire in prior art.
The utility model RS-485 order wire connecting terminal box, comprise box body, described box body is provided with several input jacks be connected with four-wire system crystal connector and an output jack be connected with four-wire system crystal connector, all there are in output jack and each input jack two first order wires connecting corresponding to order wire in four-wire system crystal connector and two second communication lines;
The first communication bus and second communication bus is also provided with in described box body, one end of described first communication bus is connected with each first order wire in each input jack, and the other end of described first communication bus is connected with first order wire of two in output jack; One end of described second communication bus is connected with each second communication line in each input jack, and the other end of described second communication bus is connected with the second communication line of two in output jack.
Further, be connected with anti-thunder tube between described first communication bus and second communication bus, described first communication bus is or/and be also connected with anti-thunder tube between second communication bus and ground.
Further, described anti-thunder tube is TED-485 anti-thunder tube.
The beneficial effects of the utility model:
1, the utility model RS-485 order wire connecting terminal box, electric energy meter is connected with the input jack of connecting terminal box by the RS-485 order wire of band four-wire system crystal connector, collector is connected with the output jack of connecting terminal box by the RS-485 order wire of band four-wire system crystal connector, thus make the connection of the RS-485 order wire of the Automatic meter reading system of employing full carrier and half carrier communication mode more quick, construction volume is less, and connection reliability is better.
2, the utility model RS-485 order wire connecting terminal box, it passes through between the first communication bus and second communication bus, the first communication bus is connected anti-thunder tube with second communication bus with between ground, thus improve the lightning protection properties of connecting terminal box and RS-485 communication system, functional reliability is higher.
Accompanying drawing explanation
Fig. 1 is the syndeton schematic diagram of electric energy meter, RS-485 order wire connecting terminal box and collector;
Fig. 2 is the line construction schematic diagram of terminal box.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one, as depicted in figs. 1 and 2, the present embodiment RS-485 order wire connecting terminal box, comprise box body 1, described box body is provided with several input jacks be connected with four-wire system crystal connector and an output jack be connected with four-wire system crystal connector, all there are in output jack and each input jack two first order wires 2 connecting corresponding to order wire in four-wire system crystal connector and two second communication lines 3;
The first communication bus 4 and second communication bus 5 is also provided with in described box body, one end of described first communication bus is connected with each first order wire in each input jack, and the other end of described first communication bus is connected with first order wire of two in output jack; One end of described second communication bus is connected with each second communication line in each input jack, and the other end of described second communication bus is connected with the second communication line of two in output jack.
The present embodiment RS-485 order wire connecting terminal box, each electric energy meter is connected with the input jack of connecting terminal box by the RS-485 order wire of band four-wire system crystal connector 7, collector is connected with the output jack of connecting terminal box by the RS-485 order wire of band four-wire system crystal connector 7, thus make the connection of the RS-485 order wire of the Automatic meter reading system of employing full carrier and half carrier communication mode more quick, construction volume is less, and connection reliability is better.
As the improvement to the present embodiment, anti-thunder tube 6 is connected with between described first communication bus and second communication bus, also anti-thunder tube is connected with between described first communication bus and ground, certainly in a particular embodiment, second communication bus also can be connected anti-thunder tube with between ground, or described first communication bus and be all connected with anti-thunder tube between second communication bus and ground.This improvement by connecting anti-thunder tube, thus improves the lightning protection properties of connecting terminal box and RS-485 communication system, and functional reliability is higher.
In the present embodiment, described anti-thunder tube is TED-485 anti-thunder tube, and lightning protection effect is good, in concrete enforcement, certainly also can adopt the anti-thunder tube of other form.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
