Defect in wire way, but this part connector is in operation, it is necessary to electric energy meter can just enter when extracting connector completely
Row automatic short circuit, arcing phenomena is occurred when causing to change table, there is potential safety hazard；Secondly, electric energy meter and connector static contact
Contact is not very reliable, and the phenomenon that moving contact misoperation causes electric energy meter metering to be forbidden easily occurs.
Utility model content
For defect and reality need present in existing electric energy meter connector, it is special that the utility model provides a kind of ammeter box
With the single-phase electric energy meter connector for changing with automatic short circuit table function.
To achieve these goals, the measure that the utility model is taken：
A kind of special single-phase electric energy meter connector that table function is changed with automatic short circuit of ammeter box, including grafting electric energy meter
Pedestal and the static contact and moving contact that are arranged in pedestal, static contact include static contact rear end and are connected with electric energy meter interference fit
Static contact front end, four static contacts being arranged side by side are divided into two groups and are fixed on base plate, and one is provided between every group of static contact
Individual moving contact, the contact of moving contact both sides not Wei Yu static contact rear end underface, two of moving contact between contact and base plate
A spring is respectively provided with, the end of clinching is fixedly connected in the middle part of moving contact, the front end of clinching is fixed on the front side of base plate, pressed
It is low early and high after domatic structure to detain；
The middle part U-shape structure of the moving contact, the end of clinching is connected in the U-type groove of moving contact；
The static contact and moving contact are antirust and the copper material for conducting electricity very well.
The beneficial effects of the utility model：Electric energy meter is to act on up and down with the active force of clinching, will not be because of the pressure of spring
Power is excessive and electric energy meter is extrapolated by clinching so that it is inaccurate effectively to prevent moving contact misoperation from causing electric energy meter to measure, and
The clinching of upper and lower active force ensure that the electric energy meter contact more reliable with connector static contact front end；Moving contact and electric energy meter are first
Cooperation after conjunction point, electric energy meter have part be pulled out connector it is not fully powered-off before, connector moving contact is and static contact
Rear end reliably closes, and effectively prevent the powered arcing phenomena for changing and occurring during table, it is ensured that the safety of operating personnel；Moving contact and
This connected mode of electric energy meter is also applicable on three-phase electric energy meter connector.

Specific embodiment
To overcome defect present in existing electric energy meter connector, reality need is met, design a kind of ammeter box special tool
There is automatic short circuit to change the single-phase electric energy meter connector (such as Fig. 1~Fig. 2) of table function, including grafting electric energy meter 9 pedestal 1 and set
Static contact 5 in pedestal 1 and moving contact 6, static contact 5 include static contact rear end 3 and quiet with what the interference fit of electric energy meter 9 was connected
Contact front end 4, four static contacts 5 being arranged side by side are divided into two groups and are fixed on base plate 8, and one is provided between every group of static contact 5
Individual moving contact 6, the contact of the both sides of moving contact 6 not Wei Yu static contact rear end 3 underface, two contacts and base plate 8 of moving contact 6
Between be respectively provided with a spring 7, the middle part of moving contact 6 is fixedly connected on the end of clinching 2, and the front end of clinching 2 is fixed on base plate 8
Front side, clinching 2 be low early and high after domatic structure；The middle part U-shape structure of the moving contact 6, the end of clinching 2 is connected to dynamic
In the U-type groove of contact 6；The static contact 5 and moving contact 6 are antirust and the copper material for conducting electricity very well.
Operation principle of the present utility model：When the corresponding connector of electric energy meter 9 is inserted, clinching 2 is pushed simultaneously by electric energy meter 9
Moving contact 6 is driven to be disconnected with static contact rear end 3, after electric energy meter 9 inserts connector in place, static contact front end 4 and energy meter terminal
Interference fit, circuit measures (such as Fig. 3~Fig. 4) through the normal work of electric energy meter 9.When electric energy meter 9 breaks down to be needed to change, electricity
While energy table 9 extracts connector, spring 7 promotes moving contact 6 and static contact rear end 3 to close, in electric energy meter 9 and static contact front end
Before 4 are fully disconnected, moving contact 6 is closed with static contact rear end 3, and circuit is through the normally operation (such as Fig. 5~Fig. 6) of moving contact 6.
The beneficial effects of the utility model：Electric energy meter is to act on up and down with the active force of clinching, will not be because of the pressure of spring
Power is excessive and electric energy meter is extrapolated by clinching so that it is inaccurate effectively to prevent moving contact misoperation from causing electric energy meter to measure, and
The clinching of upper and lower active force ensure that the electric energy meter contact more reliable with connector static contact front end；Moving contact and electric energy meter are first
Cooperation after conjunction point, electric energy meter have part be pulled out connector it is not fully powered-off before, connector moving contact is and static contact
Rear end reliably closes, and effectively prevent the powered arcing phenomena for changing and occurring during table, it is ensured that the safety of operating personnel；Moving contact and
This connected mode of electric energy meter is also applicable on three-phase electric energy meter connector.
The simple change and replacement of those ordinary skill in the art are all within protection domain of the present utility model.
