According to the relay, the first plane of the Z-shaped copper piece is connected to the wire inlet terminal, the second plane of the Z-shaped copper piece passes through the transformer, the transformer detects current which passes through the second plane, and third plane stops the side face of the transformer and is used for fixing the transformer, the transformer is fixed on the connecting plate, through the above settings, the penetration wire of the transformer is not used separately, the circuits in the relay are reduced, and the structure in the relay is clear and integrated.
Description
Technical field
The utility model relates to technical field of electricity, relates in particular to a kind of relay.
Background technology
At present, the electromagnetic relay external structure that known electric energy meter is used mainly contains Liang Zhong mechanism, a kind of is that moving contact and fixed contact are respectively drawn a wire, coordinate with corresponding current transformer, complete the synchronous transformation of electric current metering element variable, another kind is on moving contact, to draw a wire, draws wire after connecting shunt on fixed contact again, has been completed the synchronous transformation of electric current metering element variable by shunt.These two kinds of electromagnetic relays are mainly used in single household single-phase electric energy meter and single household three-phase electric energy meter.Because intelligent multifunctional multiuser electric energy meter is a kind of novel centralized multifunctional electric energy meter, if existing two kinds of electromagnetic relays are used in intelligent multifunctional multiuser electric energy meter, not too reasonable in overall structure, ampere wires and current signal line are longer, in watchcase, arrange more random, produce and testing and measuring technology very loaded down with trivial details.
Utility model content
The utility model is mainly to solve existing technical problem in prior art, thus provide a kind of simple in structure, internal wiring is smooth and easy and can simplify the relay of production technology and testing and measuring technology.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of relay of the present utility model, comprise circuit board connecting plate, at least one relay body is installed on described circuit board connecting plate side by side, described in each, on relay body, be all extended with input terminal and outlet terminal, on described input terminal, be connected with a Z-type copper sheet, on described Z-type copper sheet, be equipped with an instrument transformer, described instrument transformer is installed on described connecting plate, the first plane on described Z-type copper sheet is for being connected with described input terminal, its second plane is used for through described instrument transformer, its the 3rd plane is for instrument transformer described in backstop and as inlet wire link.
Further, described in each, the 3rd plane on Z-type copper sheet is all connected with a copper bar.
Further, described Z-type copper sheet and described input terminal are consolidated by pad.
Further, described instrument transformer is current transformer.
Compared with prior art, the utility model has the advantage of: by connect a Z-type copper sheet on input terminal, the first plane of this copper sheet is connected with input terminal, its second plane is through instrument transformer, instrument transformer detects the electric current passing in the second plane, the 3rd plane backstop is in instrument transformer side, for auxiliary fixedly instrument transformer, instrument transformer itself is also fixed on connecting plate, arrange like this, just need not use separately the line that penetrates of instrument transformer, reduced the circuit in relay, and make relay inner structure clean and tidy, integrated.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Description of reference numerals: 1, connecting plate, 2, relay body, 3, input terminal, 4, outlet terminal, 5, Z-type copper sheet, 6, instrument transformer, 7, copper bar, the 51, first plane, the 52, second plane, the 53, the 3rd plane.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Consult shown in Fig. 1 to Fig. 3, a kind of relay of the present utility model, it is characterized in that: comprise circuit board connecting plate 1, at least one relay body 2 is installed on connecting plate 1 side by side, on each relay body 2, be all extended with input terminal 3 and outlet terminal 4, on input terminal 3, be connected with a Z-type copper sheet 5, on Z-type copper sheet 5, be equipped with an instrument transformer 6, instrument transformer 6 is installed on connecting plate 1, the first plane 51 on Z-type copper sheet 5 is for being connected with input terminal 3, its second plane 52 is for passing instrument transformer 6, its the 3rd plane 53 is for backstop instrument transformer 6 and as inlet wire link.By connect a Z-type copper sheet 5 on input terminal 3, the first plane 51 of this copper sheet is connected with input terminal 3, its second plane 52 is through instrument transformer 6, instrument transformer 6 detects the electric current passing in the second plane 52, the 3rd plane 53 backstops are in instrument transformer 6 sides, for auxiliary fixedly instrument transformer 6, prevent that instrument transformer 6 from moving, instrument transformer 6 itself is also fixed on connecting plate 1, arrange like this, just need not use separately the line that penetrates of instrument transformer 6, reduced the circuit in relay, and made relay inner structure clean and tidy, integrated
In the present embodiment, the 3rd plane 53 on each Z-type copper sheet 5 is all connected with a copper bar 7.Utilize copper bar to connect the Z-type copper sheet 5 on each relay, inlet wire cable only need be connected with copper bar and electric current can be passed into each relay.Further reduce the circuit in relay, make the interior circuit of relay clean and tidy.
Preferably, Z-type copper sheet 5 is consolidated by pad with input terminal 3, convenient for production.Instrument transformer 6 is current transformer.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
