Accompanying drawing explanation
Fig. 1 shows the circuit theory diagrams of this utility model embodiment.
Detailed description of the invention
For further illustrating each embodiment, this utility model is provided with accompanying drawing.These accompanying drawings are this utility model
A part for disclosure, it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to solve
Release the operation principles of embodiment.Coordinating with reference to these contents, those of ordinary skill in the art will be understood that other
Possible embodiment and advantage of the present utility model.Assembly in figure is not necessarily to scale, and is similar to
Element numbers be conventionally used to indicate similar assembly.
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As it is shown in figure 1, this battery reverse connecting protection and warning circuit include two input terminals, it is respectively and battery
The sub-BAT+ of first input end that positive electrical connects and the second input terminal BAT-of electrically connecting with battery cathode,
This second input terminal BAT-and the first diode D29 positive electrical connect, and by this first diode D29
Negative pole access parallel circuit, the i.e. first diode D29 reversal connection；In this embodiment, this parallel circuit by
It is made up of following three circuit in parallel:
Sounding alarm circuit: this sounding alarm circuit includes speaker U1, and is electrically connected to by resistance
Between the negative pole of one input terminal BAT+ and the first diode D29；
Optocoupler drive circuit: include a photoelectrical coupler M10, the former limit of this photoelectric coupled circuit and sounding alarm electricity
Road is in parallel；Secondary has been provided with power supply VSS, is connected to after the second diode D29 of power supply VSS outfan concatenation
Photoelectrical coupler M10；As seen from the figure, the former limit reversal connection of this photoelectrical coupler M10；
Luminous alarm circuit: include LED 5 and play the resistance of metering function；This light-emitting diodes
Pipe LED5 reversal connection.
In this embodiment, this circuit operation principle is as follows:
Under normal condition, the sub-BAT+ of first input end receives anode, and the second input terminal BAT-receives
Battery cathode, now the first diode D29, LED 5, photoelectrical coupler M10 are at
Reverse blocking state, in speaker U1, no current flows through, therefore does not haves sound alarm；In like manner light-emitting diodes
Pipe LED5 will not be luminous；Photoelectrical coupler M10 does not turns on yet, the second diode D28 forward conduction, electricity
VSS road of normally serving as theme in source powers, system worked well.
When there is false wiring, i.e. first input end BAT+ receives battery cathode, the second input BAT-
Receiving anode, now circuit is in mistake wiring state, now the first diode D29, light emitting diode
LED5, photoelectrical coupler M10 are at forward conduction state, have electric current to flow through, enter in speaker D29
Row sound alarm；In like manner LED 5 turns on luminescence；Photoelectrical coupler M10 forward conduction, thus
Second diode D28 does not turns on, thus VSS power supply cannot be served as theme, road powers, and plays system reverse and connects
The function of line protection.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but the technology of art
Personnel should be understood that in the spirit and scope of the present utility model limited without departing from appended claims,
This utility model can be made a variety of changes in the form and details, be protection model of the present utility model
Enclose.
