On the process control end switch PS/ON and the end GND, and the end GND that a light emitting diode is connected to computer power is public with any one
Altogether on end, and three ends of above-mentioned connecting line plate are correspondingly connected with computer power output lead end, need to adjust in route R resistance value or
The installation polarity of light emitting diode.Not only realizing computer power can be switched on work when alternating current input is normal, and
And after computer power is switched on, positive and negative voltage end energy normal output voltage can power for light emitting diode, as long as luminous two
Pole pipe lights and power supply fan normal rotation, that is, can determine that computer power can work normally, facilitate retailer and consumer
A Function detection can be done in advance.
To sum up, the utility model can detect the quality of computer power before installation, so that retailer and consumer be made to reduce
Because installation, test, power supply are bad the loaded down with trivial details work such as power supply is replaced again, be primarily adapted for use in desktop computer.Compared to existing skill
Art, the utility model has the technical advantages that:
1, it is passed through exchange input electricity to individual computer power, computer electricity can determine by a key button of touch-switch
The quality in source, easy to operate, safety, effectively；
2, reduce manpower, material resources cost avoids unnecessary waste；
3, haulage time and expense that online trading generates due to power supply bad progress goods return and replacement have been saved.
Detailed description of the invention
Fig. 1 is the electric functional block diagram of the utility model；
Fig. 2 is the circuit diagram of the utility model；
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model on the basis of computer power original structure, increases including touch-switch and shines
The detection circuit of diode is passed through exchange input electricity to individual computer power, presses the button of touch-switch, pass through luminous two
The reaction of pole pipe and computer power fan shows testing result.
This computer power detection device is integrated on one block of function connects line plate, which is furnished with a letter as shown in Figure 2
Easy circuit.The end PS/ON, the end GND and at least one common end are set on connecting line plate, and common end includes at least one positive voltage
End and at least one negative voltage side.Touch-switch both ends are separately connected the end PS/ON and the end GND.When light emitting diode connects positive electricity
Using the LED1 in Fig. 2 when pressure side, the one end LED1 connects the end GND, and the other end connects any positive voltage terminal；When light emitting diode connects
Using the LED2 in Fig. 2 when connecing negative voltage side, the one end LED2 connects the end GND, and the other end connects any negative voltage side.Described
The end PS/ON, the end GND and other any common ends are correspondingly connected with computer power output lead end respectively.Due to computer power
Including built-in fans and output lead end, output lead end includes the end PS/ON corresponding with connecting line plate, the end GND and at least one
A common end, so touch-switch can connect the end PS/ON and the end GND of computer power by connecting line plate, LED1 can lead to
The end GND and any positive voltage terminal, LED2 for crossing connecting line plate connection computer power can connect computer power by connecting line plate
The end GND and any negative voltage side.
When implementation, the positive voltage terminal includes the end PG ,+3.3V voltage end ,+5V voltage end ,+12V voltage end, described
Negative voltage side includes -12V voltage end.Also, since the positive and negative voltage end that LED1, LED2 are connect is different, so LED1, LED2
Installation polarity it is opposite.Such as when the -12V voltage end of connecting line plate is connected to the -12V voltage of computer power, the utility model
Light emitting diode uses the connection line of LED2, is that reversed polarity is installed relative to LED1, the mesh of instruction can be lighted by reaching LED2 lamp
's.When the utility model selects different common ends, R value is different in simple circuit, realizes that LED1 or LED2 lamp is bright with this
It rises.
