The technical scheme is that a kind of wiring board for low-pressure metering box, if including main line, it is characterized in that: described wiring board is conductive copper sheet row's wiring board, conductive copper sheet row wiring board be provided with the circuit being made up of some bar shaped copper sheets, described circuit include for connect master switch and electric energy meter some live wire inlet wire circuits, for connecting some zero line inlet wire circuits of zero line and electric energy meter, for connecting some live wire outlet circuits of electric energy meter and subscriber switch, for connecting some zero line outlet circuits of electric energy meter and subscriber switch.
Described circuit two ends are equipped with the integrated clamped nipple with bar shaped copper sheet.
The preparation method of a kind of wiring board for low-pressure metering box, comprises the following steps:
A, the sectional area calculating low-pressure metering box distribution wires according to the demand of low-pressure metering box user, according to wire cross-section area, design the drawing of the conducting copper wiring board of standard；
B, secondly, according to drawing, selects the copper coin being suitable for produce some bar shaped copper sheets by punch forming or casting, is fixed on the circuit that bar shaped copper sheet is lined up as drawing on die casting；
C, by heating die casting SMC sheet or other high-temperature insulation materials suppressed with the some bar shaped copper sheets lining up circuit jointly by high temperature and be fixed into an entirety so that it is become standard circuit plate indeformable, indivisible.Also other high-temperature insulation materials can be used to suppress together with conductive copper wire row so that it is become a fixing entirety.
The copper coin that described copper coin uses usual thickness to be 3mm.
According to SMC insulation sheet material compacting wiring board, described cast temperature is about 155 DEG C, and pressure is about 100kg/mm.
When suppressing together with conductive copper wire row according to other high-temperature insulation materials, its temperature and pressure determines according to the operational characteristic of its material.
The invention have the benefit that the present invention produces conductive copper sheet row's wiring board by simple ripe technique, this wiring board is made to substitute the connection that wire realizes between multicomponent device, decrease the cost of manufacture of wire, it is to avoid owing to wire connects brought potential safety hazard；Owing to being the form of wiring board, wiring board is fixed among low-pressure metering box base, the extremely effective generation preventing Electrical Safety accident and greatly improve anti-electricity-theft performance；Use this wiring board can realize the standardization of low-pressure metering box simultaneously.
Brief description
Fig. 1 is the structural representation of conductive copper sheet wiring board in the embodiment of the present invention.
In figure, 1-bar shaped copper sheet, 2-wiring board, 3-clamped nipple, 801-live wire inlet wire circuit, 802-zero line inlet wire circuit, 803-live wire outlet circuit, 804-zero line outlet circuit.
Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of wiring board of the low-pressure metering box for single-phase four epi-positions, described wiring board 2 arranges wiring board for conductive copper sheet, conductive copper sheet row's wiring board is provided with the circuit being made up of some bar shaped copper sheets 1, and described circuit includes for the some live wire inlet wire circuits connecting master switch and electric energy meter the 801st, for connecting some zero line inlet wire circuits of zero line and electric energy meter the 802nd, for connecting some live wire outlet circuits of electric energy meter and subscriber switch the 803rd, for connecting some zero line outlet circuits 804 of electric energy meter and subscriber switch.
Described circuit two ends are equipped with the integrated clamped nipple 3 with bar shaped copper sheet 1.
Specifically, in the present embodiment, conductive copper sheet row wiring board is provided with three live wire inlet wire circuits 801, article one, total zero line inlet wire circuit 802, article four, live wire outlet circuit 803 and four zero line outlet circuits 804, wherein live wire inlet wire is divided into two branch roads and can be connected with an electric energy meter respectively, two other live wire inlet wire is connected with an electric energy meter respectively, article one, total zero line inlet wire circuit is divided into four branch roads, every branch road is connected with an electric energy meter respectively, the present embodiment can be used for assembly connection and has 1 master switch, 4 electric energy meters, the low-pressure metering box of 4 subscriber switch.
