Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described further.
As shown in figure 1, the problem existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of new
The full electricity auto-power-off device of battery, the apparatus structure is simple, with low cost, easy for installation be adapted to commercially promote.
To achieve these goals, this full electricity auto-power-off device, including：Transformer MA, bridge rectifier filter circuit N,
One pole of AC power connects one end of the transformer MA primary coils, and another pole connects metal clips I (3), and metal clips is divided into
Uncovered metal-back I (4) is put, and metal-back I accesses the other end of transformer, transformer by protective resistance R3, R4
Secondary coil output end access bridge rectifier filter circuit, after rectification, the positive pole of direct current electricity output connects the positive pole of battery, defeated
Go out negative pole and metal-back II, electromagnet II (5), resistance R7, switch S1 are sequentially connected in series and are connected on battery terminal negative；The electromagnet
II is positioned in uncovered metal-back II (2), and the opening of metal-back II arranges metal clips II (1)；
Arrange resistance R8, electromagnet I (6), the series circuit of resistance R9 and on metal clips II and switch S1 one end；
Arrange switch S2, electric capacity C, resistance R5, the series circuit of resistance R6 to be connected in parallel on metal clips II and metal-back II.
Further, when the electromagnet II is powered, metal clips II is attracted and contacts with metal shell II；Electromagnet II is not
