Abstract
The utility model provides a low-cost one-way local cost-control electric energy meter, which comprises an electric energy meter shell and a main circuit board arranged inside the electric energy meter shell. The main circuit board is provided with a microprocessor, a metering chip and a transformer. The utility model is characterized in that a second circuit board is also arranged inside the electric energy meter shell; the second circuit board is vertically welded on the main circuit board; and the bottom of the transformer of the main circuit board is provided with a groove. According to the low-cost one-way local cost-control electric energy meter provided by the utility model, the groove is dug on the bottom of the transformer on the main circuit board, the groove-portion circuit board is made into the second circuit board, and the second circuit board is vertically welded on the main circuit board. Thus, functions of the electric energy meter maintain unchanged, lateral dimension is reduced, and space usage is decreased. Simultaneously, consumption of the circuit board material is saved, production cost and time are reduced; and production efficiency is raised.
Description
Technical field
The utility model belongs to the electric energy meter field, is specifically related to a kind of unidirectional local expense control electric energy meter cheaply.
Background technology
Electric energy meter is the instrument of measuring electric energy, mainly comprises the electric energy meter housing, and is arranged on the circuit board in the electric energy meter housing, and this circuit board is provided with computation chip, transformer, microprocessing unit and display unit etc.Owing to the electronic devices and components that need on the circuit board to arrange are more, so the volume of circuit board is all bigger, and this takes up room bigger with regard to the integral body that has caused electric energy meter.
The utility model content
The utility model is at above-mentioned the deficiencies in the prior art, and a kind of unidirectional local expense control electric energy meter cheaply is provided, and this is unidirectional local expense control electric energy meter little, the low cost of manufacture that takes up room cheaply.
The utility model is achieved by the following technical solution:
Control electric energy meter is taken in a kind of unidirectional this locality cheaply, comprises the electric energy meter housing, and is arranged on the main circuit board in the electric energy meter housing, and described main circuit board is provided with microprocessor, computation chip and transformer; It is characterized in that, also be provided with a sub-circuit board in the described electric energy meter housing, vertical the inserting of described sub-circuit board is welded on the main circuit board; The bottom of transformer is provided with groove on the described main circuit board.
Further setting of the present utility model is, the form fit of described sub-circuit board and transformer bottom groove.
Further setting of the present utility model is that described sub-circuit board is provided with display screen.
Further setting of the present utility model is that described sub-circuit board is positioned at an end of main circuit board.
Unidirectional local expense control electric energy meter cheaply described in the utility model digs by the bottom of transformer on main circuit board establishes groove, and the circuit board making of groove part become sub-circuit board, vertical inserting is welded on the main circuit board, make the function of electric energy meter remain unchanged, and lateral dimension is reduced, and takes up room to reduce; Save the consumption of circuit board material simultaneously, reduced manufacturing cost and time, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of unidirectional local expense control electric energy meter cheaply described in the utility model.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of unidirectional local expense control electric energy meter cheaply, comprises the electric energy meter housing, and be arranged on the main circuit board 1 in the electric energy meter housing that described main circuit board 1 is provided with microprocessor, computation chip and transformer 2; Also be provided with a sub-circuit board 3 in the described electric energy meter housing, described sub-circuit board 3 vertical inserting are welded on the main circuit board 1; The bottom of transformer 2 is provided with groove 4 on the described main circuit board 1.Original circuit board can be as the raw material of making sub-circuit board 3 in the groove 4, and namely the form fit of described sub-circuit board 3 and transformer 2 bottom grooves 4 can be saved cost like this, avoids the waste of material.On the described sub-circuit board 3 display screen can be set.Described sub-circuit board 3 preferably is arranged on an end of main circuit board 1.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
