Abstract

The utility model discloses a top-in bottom-out electronic type single phase electric energy meter based on a same wiring terminal block, relating to an electronic single phase electric energy meter. In the base (1), a terminal block (2), a current divider (4), a metering circuit board (5) and a terminal block (2) are sequentially connected from top to bottom; the outsides of the upper and lower terminal blocks (2) are respectively connected to an upper cover plate (3) and a lower cover plate (12), and fixed by screws (13) and seals (14). The structure of the terminal block (2) is as follows: an insulating pedestal (2.1) is provided with a 220V wiring terminal (2.2) and a weak current signal wiring terminal (2.3). Since the upper and lower terminal blocks have the same structure, the kinds of moulds for the terminal blocks are reduced, the cost of the top-in bottom-out electric energy meter is lowered, and the utility model is suitable for all electronic single phase electric energy meters.

Description

Go out electronic single-phase electrical energy meter based under identical terminal block enterprising

Technical field

The utility model relates to a kind of electronic single-phase electrical energy meter, relates in particular to a kind ofly to go out electronic single-phase electrical energy meter based under identical terminal block enterprising.

Background technology

Existing electronic single-phase electrical energy meter (abbreviation electric energy meter) mainly is made up of shell, metering circuit plate and display three parts; Shell mainly is made up of end of incoming cables stroma, upper end cover, base, loam cake, leading-out terminal stroma, bottom end cover etc.

Existing a kind of " going out under enterprising " inlet wire of electronic single-phase electrical energy meter, the top and bottom that the leading-out terminal stroma is placed in electric energy meter respectively, the position is clearly demarcated, can effectively take precautions against the current bypass stealing.

Above-mentioned end of incoming cables stroma and leading-out terminal stroma be not owing to optimize the putting position of verification pulse output end and 485 mouthfuls, so can not be designed to the same, make that like this mould of production end of incoming cables stroma and leading-out terminal stroma is also different, increased buying of electric energy meter parts and production procedure handling cost.Simultaneously, because the enterprising terminal base that goes out down of each electric energy meter manufacturer is different again each other, cause electric energy meter checking device can not satisfy the enterprising verification that goes out electric energy meter down of different manufacturers simultaneously, work efficiency is low.

Along with the enterprising a large amount of uses that go out electric energy meter down, the problems referred to above must effectively be solved.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that has technology to exist, and provides a kind of and goes out electronic single-phase electrical energy meter based under identical terminal block enterprising.

The purpose of this utility model is achieved in that

The utility model comprises base, terminal base, upper cover plate, shunt, metering circuit plate, carriage, nameplate, frangible circle, loam cake, O-ring seal, hook, lower cover, screw and seal;

In base, from the top to the bottom, be provided with the terminal base, shunt, metering circuit plate and the terminal base that connect successively;

Between the upper and lower wall of base and upper and lower end stroma, also be connected with O-ring seal respectively;

Outside at the upper and lower end stroma is connected with upper cover plate and lower cover respectively, fixes by screw and seal;

In the front of base, from inside to outside, be provided with the carriage, nameplate, loam cake and the frangible circle that connect successively;

Be provided with hook at top, base 1 back side.

The utility model compared with prior art has following advantage and good effect:

1, because the upper and lower end stroma is a kind of same structure, reduces terminal base mould kind, reduced the cost of " going out under enterprising " electric energy meter;

2, upper and lower table lid and bottom seat is one-time fixed by screw and seal, can't restore after opening electric energy meter; If the electricity filching behavior of electric energy meter structure takes place to destroy, the stealing vestige is fairly obvious;

3, the unification of being convenient to finish on electric energy meter checking device detects.

In a word,, therefore wide application prospect is arranged, be applicable to all electronic single-phase electrical energy meters because the utility model performance and price is not high.
