T.t 的 Power 燒了 - 3C

power本身是否著火要看內部，不過因為power有鐵殼，本身燒起來會控制在鐵殼裡面，但
假如是外部線組起火燃燒的話，就很難說
如果最後檢視發現線組部分碳化最嚴重的話，表示可能是從線路燒起來

分享一個之前遇到的案例

上圖只是讓3.3v碰觸到外殼，就導致該線路的3.3v整條燒熔

因為線路與外殼相碰的導通路徑是線路>接觸點>外殼>POWER外殼>POWER內GND鎖點，其阻
抗略高於線路間直接短路，所以可能會被POWER視為是大電流負載，而發生保護無法正常
被觸發

模組化部分因為多了插頭與插座，會多一個接觸阻抗

夾到/壓到/過度拉扯，導致內部線芯刺破絕緣皮，短路
