Specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to Fig. 1, the utility model provides a kind of switch control plate suitable for ATX power supply, comprising: with ATX power supply The ATX power interface of connection, the fictitious load being electrically connected with the ATX power interface are electrically connected with the ATX power interface Manual control module, with the ATX power interface be electrically connected automatic control module and with the manual control module And the jumper switch that automatic control module is electrically connected.The jumper switch includes three pins.

It please refers to Fig. 2 and schemes, 4, the automatic control module includes and door U1, analog switch U2 and first resistor R1, the one end the first resistor R1 are connect with ATX power interface, and the other end is connect with the first input end A with door U1, it is described with The third pin PS-ON-2 of the second input terminal B and jumper switch J1 of door U1 are connect, the output end Y and simulation with door U1 The 4th pin of switch U2 connects, and terminates ATX power interface with the operating voltage of door U1.The first pin of the analog switch U2 It is connect with the first pin of jumper switch J1, the second pin and third pin of analog switch U2 is grounded, and the 5th pin meets ATX Power interface.

Under insertion power supply line, primary condition, first input end A and the second input terminal B with door U1 are high level, with The output end Y of door U1 also exports high level, and analog switch U2 is promoted to work, and the first pin PS-ON output of jumper switch J1 is low Level, ATX power supply are started to work.

Please refer to Fig. 3 and Fig. 4, the manual control module include key switch J11, reverser U3, trigger U4, First to the 5th capacitor C1-C5 and the second to the 4th resistance R2-R4.The one end the key switch J11 and first capacitor C1 mono- The second pin connection at end, second one end capacitor C2, the one end second resistance R2 and reverser U3, the key switch J11 other end, The first capacitor C1 other end and second capacitor C2 other end ground connection, the third pin ground connection of the reverser U3, the 4th draws Foot is connect with the third pin of one end of third capacitor C3, one end of 3rd resistor R3 and trigger U4, the 5th pin with And another termination ATX power interface of second resistance R2.The first pin and ATX power interface, trigger of the trigger U4 One end connection of the 14th pin and the 5th capacitor C5 of U4, the 5th capacitor C5 other end ground connection, the second of trigger U4 are drawn Foot is connect with its 6th pin, and the 4th pin is connect with one end of one end of the 4th capacitor C4 and the 4th resistance R4, and the 4th Another termination ATX power interface of resistance R4, the third capacitor C3 other end, the 3rd resistor R3 other end and the 4th capacitor C4 are another End ground connection, the 5th pin of the trigger U3 are connect with the second pin PA-ON-1 of jumper switch J1, and the 7th of trigger U4 the Pin ground connection.
