Description
Technical field
The utility model relates to field of computer technology, is specifically related to a kind of device for preventing power failure of computing machine.
Background technology
The power supply mode that desktop computer adopts is at present that main frame is directly connected with power supply; therefore when having a power failure or power supply breaks down, main frame is shut down because losing power supply immediately; have a strong impact on the one hand the serviceable life of the each parts of desktop computer; on the other hand; make file that user editing before power failure because not preserving and lose in time, and cannot recover or be difficult to recover.In prior art, have accumulator power supply is in support installed in cabinet, but back-up source just uses once in a while, owing to can not guaranteeing that for a long time circuit is always in channel status, inconvenience while causing the later stage to be used.
Summary of the invention
The purpose of this utility model is to provide a kind of device for preventing power failure of computing machine, and it can prevent computer circuit breaking, can guarantee under the state in path of circuit simultaneously, easy to use, easy and simple to handle, precise control.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises power configuration device 1, battery charger 2, battery pack 3, mainboard 4, it also comprises relay one KM1, relay two KM2, alarm 5, the input of power configuration device 1 is all connected with power supply with the input end of battery charger 2, the output terminal of power configuration device 1 is connected with one end of relay one KM1 coil, the other end of relay one KM1 coil is connected with one end of relay one KM1 normally opened contact, the other end of relay one KM1 normally opened contact is connected with the power end of mainboard 4, the output terminal of battery charger 2 is connected with the input end of battery pack 3, the output terminal of battery pack 3 respectively with one end of relay two KM2 coils, one end of relay two KM2 normally opened contacts connects, the other end of relay two KM2 normally opened contacts is connected with alarm 5, the other end of relay two KM2 coils is connected with one end of relay one KM1 normally closed contact, the other end of relay one KM1 normally closed contact is connected with the power end of mainboard 4.
Principle of work of the present utility model is: when having electricity, by power configuration device 1, provide power supply for mainboard, now relay one KM1 coil obtains electric, the normally opened contact closure of relay one KM1, relay one KM1 normally closed contact disconnects, when having a power failure, relay one KM1 coil losing electricity, the normally opened contact of relay one KM1 disconnects, relay one KM1 normally closed contact closure, now by battery pack 3, powered, relay two KM2 are for detection of the circuit of battery pack 3, when the service interruption of battery pack 3, relay two KM2 coil losing electricities, relay two KM2 normally opened contact closures, alarm 5 powers alarm.
The utlity model has following beneficial effect: can prevent computer circuit breaking, can guarantee under the state in path of circuit simultaneously, easy to use, easy and simple to handle, precise control.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
