Problems solved by technology

[0002] After the entertainment functions of mobile phones began to appear, users’ habits of playing games through game consoles and computers began to change, and mobile games became popular all over the world. One of the main motivations for young people to use mobile phones today is to play mobile games , this situation is also spreading in China, so more and more mobile games are developed, and after each mobile game is developed, it takes a long time and repeated tests before it can be put into use. The market is for user experience. Many times when the game tester is tested, the excessive voltage will affect the game test and reduce the pass rate of the game test. When the power is turned on, the instantaneous high pulse voltage will reduce the game tester. Test performance, reduce its service life

Abstract

The invention discloses an overvoltage protection circuit for mobile phone game testing, which comprises a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a first potentiometer, a second potentiometer, a time base chip, a three-terminal voltage regulator, a power switch, a first resistor, a second resistor, a first rectifier, a second rectifier, a transistor, a first diode, a second diode, a third diode, a fourth diode, a fifth diode, a relay and a transformer. The overvoltage protection circuit has a dual protection function; the overvoltage protection circuit can protect a mobile phone game tester when mains supply voltage is overhigh, and also can prevent transient high impulse voltage from impacting the mobile phone game tester, thus benefiting the testing of a mobile phone game and increasing the pass rate of testing; moreover, the overvoltage protection circuit has a simple circuit structure and is low in fabrication cost, which is favorable for popularization.

Description

technical field [0001] The invention relates to an auxiliary circuit for mobile game testing, in particular to an overvoltage protection circuit for mobile game testing. Background technique [0002] After the entertainment functions of mobile phones began to appear, users’ habits of playing games through game consoles and computers began to change, and mobile games became popular all over the world. One of the main motivations for young people to use mobile phones today is to play mobile games , this situation is also spreading in China, so more and more mobile games are developed, and after each mobile game is developed, it takes a long time and repeated tests before it can be put into use. The market is for user experience. Many times when the game tester is tested, the excessive voltage will affect the game test and reduce the pass rate of the game test. When the power is turned on, the instantaneous high pulse voltage will reduce the game tester. Test performance, redu...
