Power output protection device

Abstract

The invention discloses a bad-proof device of power output, which contains power supplier with circuit board in the power supplier, wherein multiple electric areas with different potentials are set on the circuit board; the input port to connect the electric area is set on the surface of power supplier; a connecting wire is set on the output power port with one end possessing a connecting port corresponding to the output power port and the other end possessing a plugging port to connect computer host; the ps-on signal foot position to control the power is set on the plugging port; the image position of output power port corresponding to ps-on signal foot position on the plugging port is empty foot position or HIGH potential; when the user reserves the connecting port and plugging port, the ps-on signal can't be transmitted through hollow foot position of output power port or HIGH potential to protect the electronic device and make the circuit layout of the circuit more elastic.

Problems solved by technology

[0003] The 24pin power transmission port of the standard EPS specification power supply in the market is a ps-on signal terminal on the 16th pin, while the 20pin power transmission port of the ATX specification power supply is a ps-on signal terminal on the 14th pin. The connection line has a plug port to supply power to the computer motherboard, and the connection port at the other end is connected to the power supply port of the power supply to transmit multiple potentials (such as +5Vdc, +3.3Vdc, +12Vdc. .. etc.), the ps-on High / Low signal of the motherboard is transmitted to the inside of the power supply through the plug-in port and the 16th pin of the power transmission port to control the opening and closing operation of the power supply, in accordance with the standard EPS specification Take the power transmission port as an example, the voltage specification and the function definition of the signal terminal, the definitions from the 1st pin to the 24th pin are: +3.3Vdc, +3.3Vdc, GND, +5Vdc, GND, +5Vdc, GND , POK, +5Vsb, +12Vdc, +12Vdc, +3.3Vdc, +3.3Vdc, -12Vdc, GND, PS-ON, GND, GND, GND, N / C, +5Vdc, +5Vdc, +5Vdc, +5Vdc , GND, the definition of the plug port from the 1st pin to the 24th pin is the same as above; the power output lines sold in the market are usually equipped with a fool-proof structure, so that the connection port or the plug port will not be damaged due to The user wrongly inserts the motherboard or the power supply at the opposite angle, causing damage to the mainboard or the power supply; The connection port connected to the power supply is wrongly plugged into the motherboard. If the user connects the connection port and the plug port to the motherboard and the power supply in the opposite and wrong combination and starts it up, the connection port and the power supply have been used. The ps-on signal terminal responsible for transmitting the ps-on signal in the plug-in port is located on the 16th pin (the ATX standard 20-pin connection port is located on the 14th pin), and the ps-on signal sent by the motherboard will still pass through the connection port from the plug-in port The 16th pin (or 14th pin) of the power supply is transmitted to the inside of the power supply, so that it starts the main power supply and causes damage to the motherboard, which brings great trouble to the user, and the power transmission port of the existing power supply, and its internal circuit board The pin configuration of the power connection area is to match the pins of the plug-in port on the motherboard, which makes the circuit board circuit layout of the power supply rigid and inflexible. The pins on the power transmission port need to be connected to the The equipotential connection area on the circuit board leads to frequent detours, which virtually increases the manufacturing cost of the manufacturer
