A high-temperature automatic power-off pc power supply

Abstract

The invention discloses a high-temperature automatic power-off PC power supply in the technical field of computer power supplies. It includes a power supply casing. A plug is installed on the right end of the power supply casing. The riser portion of the L-shaped terminal is provided with a first contact block on the side close to the plug, and a frame is provided on the left side of the inner cavity of the power supply casing. When the present invention is used, when the internal temperature of the power supply reaches the trigger temperature, At this time, the expansion of alcohol just makes the channel opening on the movable ejector pin be located at the intersection of the cross-shaped tube. At this time, the power-off push rod is allowed to act, and the elastic push rod mechanism is pushed to make the L-shaped connection between the electrified contact and the plug. The column is detached. This design method solves the problem that the power will be cut off when the trigger temperature is not reached in the prior art. Electricity is more timely.

Description

technical field [0001] The invention relates to the technical field of computer power supplies, in particular to a high-temperature automatic power-off PC power supply. Background technique [0002] The application of computers is becoming more and more common in China. At present, the power supply used in desktop computers is equipped with a cooling device inside, but the cooling device of the power supply will be clogged with dust after long-term use, which will easily cause the fan to stop rotating. Inside, it is not easy to be found, which will cause the internal temperature of the power supply to rise rapidly, directly causing damage to the power supply, so a desktop computer power supply with high temperature automatic power off is needed. [0003] Patent No. CN201810447008.0 discloses a high-temperature automatic power-off desktop computer power supply, including a power supply housing, one end of the power supply housing is fixedly installed with a power plug, one en...

Problems solved by technology

[0004] Although the above-mentioned device can realize high-temperature power outage of the power supply, it still has the following problems. Since the heat dissipation and expansion process of alcohol continues with the temperature rise, in order to avoid power outage caused by alcohol expansion before the temperature reaches the trigger temperature, the device passes Set springs, ejector rods, chute and other structures to achieve the blocking effect before reaching the trigger temperature, but it is difficult for this device to control the blocking force, and it is very easy to have the problem of power failure when the trigger temperature is not reached, and the possibility of random errors large, impractical
