Description
Technical field
This utility model is related to measuring instrumentss class technical field, specially a kind of anti-interference structure of electric energy meter.
Background technology
For existing module electric energy meter, its mode of connection is, starts to exchange fire line line in one end of electric energy meter, another
Terminal connecting zero line line, that is, the not separated connected mode of strong and weak electricity, but there is magnetic field around forceful electric power, its meeting signal to light current
Produce impact, be embodied in: if cable television line, signal would not will be apparent that；If telephone wire, phone will go out
Existing noise；If netting twine, network transfer speeds will be affected, and serious meeting causes communication success rate to reduce, in addition
Wiring also easily malfunctions, if strong and weak electricity wrong can burn out ammeter, and then potential safety hazard occurs.
Content of the invention
For the problems referred to above, this utility model provides a kind of anti-interference structure of electric energy meter, and its structure is simple, can make strong
Light current separately, thus improving capacity of resisting disturbance, is user-friendly to.
Its technical scheme is such, and it includes watchcase, and the bottom of described watchcase is provided with guide-track groove it is characterised in that institute
The two ends stating watchcase are stepped, are equipped with terminals, the terminals of described watchcase side in two stepped end of described watchcase
Connect civil power, the terminals of described watchcase opposite side connect signal output part；Described civil power includes zero line, zero line side, described
Signal output part includes pulse output end, rs485 communication output, and the top terminals in described watchcase side are zero line,
Corresponding bottom terminals are zero line side；It is pulse output end in the top terminals of described watchcase opposite side, corresponding bottom
Terminals are rs485 communication output.
It is further characterized by, and the top terminals in described watchcase side are zero line side, corresponding bottom terminals
For zero line；It is rs485 communication output in the top terminals of described watchcase opposite side, corresponding bottom terminals are pulse
Outfan；
The top of the connecting end surface of described watchcase is provided with sliding-rail groove, and slide block is installed in described sliding-rail groove, described slide block top
Portion is provided with jack.
The beneficial effects of the utility model are, connect civil power by the terminals in watchcase side, the connecing of watchcase opposite side
Line end connects signal output part, so that forceful electric power is separately connected with weak current part phase, effectively prevents forceful electric power from disturbing, strong antijamming capability,
And the situation of wrong line loss bad ammeter can be avoided.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, this utility model includes watchcase 1, the bottom of watchcase 1 is provided with guide-track groove 2, and the two ends of watchcase 1 are in rank
Scalariform, is equipped with terminals in two stepped end of watchcase 1, and the terminals of watchcase 1 side connect civil power, watchcase 1 opposite side
Terminals connect signal output part；Civil power includes zero line, zero line side, and signal output part includes pulse output end, rs485 communication
Outfan, the top terminals 2-1 in watchcase 1 side is zero line, and corresponding bottom terminals 2-2 is zero line side；In watchcase 1
The top terminals 3-1 of opposite side is pulse output end, and corresponding bottom terminals 3-2 is rs485 communication output, then this electricity
Forceful electric power can be made separately to be connected with weak current part by table, effectively prevent forceful electric power interference, strong antijamming capability, and wrong line loss can be avoided
The situation of bad ammeter；And the top of the connecting end surface of watchcase 1 is provided with sliding-rail groove 4, the depth of sliding-rail groove 4 is 2mm, and slide block 5 is installed
In sliding-rail groove 4, slide block 5 top is provided with jack 6, then electric energy meter is installed not only by guide-track groove 2, also can pass through slide block
5 skid off in sliding-rail groove 4, carry out in-wall mounting, meet multiple installation requirements, convenient and practical.
Top terminals 2-1 in watchcase 1 side is zero line side, and corresponding bottom terminals 2-2 is zero line；In watchcase
The top terminals 3-1 of 1 opposite side is rs485 communication output, and corresponding bottom terminals 3-2 is pulse output end.
