As this utility model further scheme: described switch K connects together with opening computer switch
Gang switch.
Compared with prior art, the beneficial effects of the utility model are: this utility model computer ATX electric power controller exists
Computer is opened Shi Yu city and is electrically connected, and electrically disconnected with city after shut down, it is possible to be effectively prevented thunderbolt, and safety is high.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of computer ATX electric power controller.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of computer ATX electric power controller, including relay J 1, electricity
Resistance R1, diode D1, audion VT1, switch K, battery E1 and battery E2, described diode D1 negative pole connects diode D2 respectively
Negative pole and relay J 1 coil, the relay J 1 coil other end connects diode D1 positive pole and audion VT1 colelctor electrode respectively, and three
Pole pipe VT1 base stage connects resistance R1, and the resistance R1 other end connects input V3 and switch K respectively, and the switch K other end connects battery
E2 positive pole, battery E2 negative pole connecting triode VT1 emitter stage, battery E1 negative pole, diode D3 positive pole and relay J 2 line respectively
Circle ground connection, diode D3 negative pole connects the relay J 2 coil other end and input V1 respectively, and battery E1 positive pole connects relay
Device J2 contact J2-1 pin 1, relay J 2 contact J2-1 pin 3 connects input V3, and relay J 2 contact J2-1 pin 2 connects
Diode D2 positive pole；Described input V1, V2 and V3 are three outfans of ATX power supply, and voltage is respectively 5V, 12V and 3.3V；
Described switch K is to switch, with opening computer, the gang switch connected together.
Referring to Fig. 1, relay J 1 is the output control switch of ATX power supply, time normal, the voltage of E1 by J2-1, two
Pole pipe D2, relay J 1 powers to the colelctor electrode of VT1, and when pressing K, E2 provides voltage by the base stage giving VT1 after resistance R1,
VT1 turns on, J1 adhesive, and ATX power supply is open-minded, and input V1 ~ V3 starts to power to circuit, after unclamping opening computer switch, and K
Disconnecting, the voltage of V3 makes VT1 still turn on, but now the voltage of J1 is provided by ATX power supply.The voltage of V1 makes relay
J2 adhesive, battery E1 stops powering to J1, then is provided 12V voltage by V2.When being shut down by computer, the PS-ON of ATX power supply
(not shown) recovers high level, V2 and V3 also stops power supply, and J1, J2 disconnect, and make circuit quit work.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
