Abstract
The utility model discloses a three-phase electric energy meter meeting ANSI (American National Standards Institute) standard, which comprises a power supply PCB board, a current transformer with a current line, a current terminal and a pulse terminal, wherein a connection needle is arranged on the current transformer, and the connection needle is directly connected with the power supply PCB board. A plurality of notches are arranged on the power supply PCB board, and the port of the pulse terminal is inserted into the notches and is welded through soldering. The connection needle is additionally arranged on the current transformer, and is directly connected with the power supply PCB board by the connection needle, so that the number of welding spots on the power supply PCB board and the current transformer is reduced, a plurality of cables are not required, and the manufacturing cost and the raw material cost are reduced. Moreover, the connection way between the pulse terminal and the power supply PCB board also greatly reduces the use of a support frame of the electric energy meter, thus promoting the speed of assembly, and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of instrument and meter, relates in particular to a kind of three-phase electric energy meter that meets ansi standard.
Background technology
At present, the three-phase electric energy meter that meets ansi standard has generally comprised power supply pcb board, current transformer, current terminal and pulse terminal.When assembling, all be to adopt soft connecting line directly to connect between these four parts of electric energy meter, the power supply pcb board then is on the support that is fixed in the electric energy meter.This traditional fit, not only need to increase a plurality of pads, bring very big difficulty, but also will in electric energy meter, increase the support of a fixed power source pcb board to production, with one group of connecting line of drawing from current transformer, current terminal, thus the production cost that increases.
The utility model content
The purpose of this utility model is to provide the three-phase electric energy meter that a kind of production cost is lower, the processing assembling meets ansi standard more efficiently.
The three-phase electric energy meter that meets ansi standard that the utility model provides comprises current transformer, current terminal and the pulse terminal of power supply pcb board, charged streamline, and described current transformer is provided with the connection pin, and this connection pin directly is connected with the power supply pcb board.
Have some notches on the described power supply pcb board, the port of described pulse terminal inserts in the notch and by soldering and connects.
Described electric current line and current terminal are directly fixing by screw.
Described power supply pcb board partly is connected with the ammeter metering by winding displacement.
The utility model directly is connected with the power supply pcb board by it owing to set up the connection pin on current transformer, has reduced the quantity of solder joint on the power supply pcb board summation current transformer and has no longer needed many cables, has reduced the manufacturing cost and the cost of raw material.And this connected mode of pulse terminal and power supply pcb board has also significantly reduced the utilization of electric energy meter medium-height trestle, and the speed when having accelerated assembling has improved production efficiency.
