Description
Technical field
The utility model is related to electric energy meter technical field more particularly to a kind of electric energy meter external communication interfaces.
Background technology
Electric energy meter is equipped with external communication interface, is mainly used for carrying out communication with outside kilowatt meter recorder and connecting, but existing
The communication interface of technology is two groups of wire connection terminals, needs user oneself that kilowatt meter recorder and wire connection terminal are carried out wiring manually, this
Not only wiring bothers sample, and use is not very convenient, and cannot power to kilowatt meter recorder, so externally fed equipment needs to carry
Power supply so that kilowatt meter recorder cost is higher.
Invention content
Technical solution is used by the utility model：It provides logical outside a kind of easy-to-connect and self-powered electric energy meter
Communication interface.
Technical solution is used by the utility model：A kind of electric energy meter external communication interface, including circuit board and sets
Two groups of connection terminals on circuit boards are put, every group of wiring includes positive and negative connector, it further includes two RJ45 interfaces, and each
RJ45 interfaces are equipped with eight connectors, and the one the second connector is connect respectively with the positive and negative current electrode in electric energy meter, and the 4th
5th connector is connect respectively with the positive and negative connector of one of which connection terminal, and the 3rd the 6th connector is pre- connector of leaving blank, and the seven the
Eight connectors are grounded.
Using more than structure compared with prior art, the utility model has the following advantages：It is set on connection terminal
RJ45 interfaces, such wiring is more convenient, and RJ45 interfaces are connect with the current electrode in electric energy meter, and such kilowatt meter recorder is just
Do not need to charged again, it is only necessary to by kilowatt meter recorder be plugged on RJ45 interfaces can work once electrified, it is more convenient to use, and
And the signal quality of RJ45 interfaces in itself is also preferable.
Preferably, described two RJ45 interfaces are arranged at board edge, and the lower end of two RJ45 interfaces with
Circuit board lower end is aligned.In this way, user's grafting is more convenient, and more beautiful.
Preferably, it further includes the rack for placing kilowatt meter recorder.It is in this way, more convenient during user's meter reading
Easily.
Description of the drawings
Fig. 1 is the structure diagram of the utility model electric energy meter external communication interface.
As shown in the figure：1st, circuit board；2nd, RJ45 interfaces.
Specific embodiment
The utility model is described further with specific embodiment below in conjunction with attached drawing, but the utility model is not only
It is limited to detailed description below.
A kind of electric energy meter external communication interface, including circuit board 1 and setting two groups of connection terminals on the circuit card 1,
Every group of wiring includes positive and negative connector, it further includes two RJ45 interfaces 2, and each RJ45 interfaces 2 are equipped with eight connectors, described
The one the second connectors are connect respectively with the positive and negative current electrode in electric energy meter, the 4th the 5th connector respectively with one of which connecting pin
The positive and negative connector connection of son, the 3rd the 6th connector are pre- connector of leaving blank, and the 7th the 8th connector is grounded.
Described two RJ45 interfaces 2 are arranged at 1 edge of circuit board, and the lower end of two RJ45 interfaces 2 with circuit board 1
Lower end is aligned.
It further includes the rack for placing kilowatt meter recorder.
It is now also required to set one and the plug of RJ45 Interface Matchings on kilowatt meter recorder when in use, it thus can be direct
Plug is inserted into RJ45 interfaces and is communicated and powered.
