三天前,我的鼠标不幸夭折了。上街新购,这三里多路不说,又得花钱。伤心之余,决定开膛动手术,幸还有万用表可以使用,细细测量一番,不禁失笑:只是断了一根线!原来这鼠标前面十厘米左右的地方已断。拿出电烙铁仔细焊好一试,哈,完好如初。 高兴之后,又对以前损坏的旧鼠标进行了一翻研究,大都是一个毛病,照方抓药,基本痊愈。进一步分析电路及原理,发现除了连线之外,鼠标是不容易损坏的,且内部电路一致,零件大都可互换(注意大小,个头不一),PS/2口与串口除接口不一致外,没有区别。
Three days ago, my mouse unfortunately died. New purchase on the street, this three miles do not say, have to spend money. Sadly, decided to open surgery, but fortunately there are multimeter can be used, thin measurements, can not help but laugh: just broke a line! The original ten centimeters in front of the mouse has been cut off. Take out the soldering iron carefully soldered a try, ha, intact. Pleased, after the previous damage to the old mouse for a double study, mostly a problem, according to prescription drugs, the basic recovery. Further analysis of the circuit and the principle and found that in addition to the connection, the mouse is not easy to damage, and the internal circuitry is consistent, most of the parts are interchangeable (note the size, different), PS / 2 port and serial interface in addition to inconsistent, no difference.
