    耳机插头修复记

    情况:耳机插头部位的线断裂,导致声音时断时续。
    理论准备:耳机的插头大多是三节的.第一节是左声道,第二节是右声道,第三节大的是公共地,这样就分出两条线,总共四条芯.一般是红,绿,铜,铜.常规情况是红色搭配一条铜色的做一个声道,绿色搭配一条铜色的做一个声道.
    工具准备:大功率烙铁一把40W。我的是20w的,凑和用拉。焊锡丝。松香,这个是必须的,可以增加焊锡流动。我没有找到,焊起来那个累啊~AB胶。一种胶水,硬了之后很坚固,不错的。另有小刀,把原耳机的客刮掉。老虎钳,固定用。万用表,可以测试是哪个声道坏了。我的找不到了,不过也没什么影响。
     
    步骤,先把耳机线剪断,剥开线,理出各色线。把插头外面的塑料刮去,剩下芯子。然后用烙铁把各色线焊到正确位置上。最后把AB胶涂在上面,等胶水干了就成了。等胶水干了以后插上mp3一听,恩,和原来一样~胶水部分也够结实。就是忘记把套加在上面了,比较难看,等以后有了松香再加工一次。
