我(wo)有一(yi)個朋友(you)，上網(wang)買了(le)根充(chong)電線(xian)，說什么(me)充(chong)電沒啥(sha)問題，數(shu)據(ju)線(xian)還是新的，沒見著什么(me)破損(sun)，但(dan)就是莫名其妙的傳輸不(bu)了(le)數(shu)據(ju)... 什么(me)原因呢？因為(wei)他賣的是充(chong)電線(xian)不(bu)是數(shu)據(ju)線(xian)啊，自然傳輸不(bu)了(le)數(shu)據(ju)了(le)。估計有許多人都和我(wo)這位(wei)朋友(you)一(yi)樣(yang)，分(fen)不(bu)清充(chong)電線(xian)和數(shu)據(ju)線(xian)的區別吧今天電源適配器(qi)廠家(jia)就來為(wei)大家講講這其(qi)中(zhong)的(de)道道。

簡單來說，充(chong)(chong)電(dian)線(xian)(xian)(xian)(xian)與數(shu)據(ju)線(xian)(xian)(xian)(xian)二(er)者不能等同，數(shu)據(ju)線(xian)(xian)(xian)(xian)可以充(chong)(chong)當充(chong)(chong)電(dian)線(xian)(xian)(xian)(xian)，充(chong)(chong)電(dian)線(xian)(xian)(xian)(xian)卻不一(yi)定(ding)能當數(shu)據(ju)線(xian)(xian)(xian)(xian)。區(qu)別就在于，很多時(shi)候我們花低價錢買了一(yi)根數(shu)據(ju)線(xian)(xian)(xian)(xian)回去發(fa)現它只能充(chong)(chong)電(dian)，無法(fa)傳輸數(shu)據(ju)，就是(shi)這個道理了。

為(wei)什么充(chong)電無法傳輸數(shu)據(ju)(ju)呢?將USB頭正面向著自己，有(you)觸片那(nei)面向上，從(cong)左(zuo)到右(you)，那(nei)些(xie)觸片連(lian)接(jie)的線(xian)(xian)(xian)(xian)(xian)(xian)對應(ying)的功(gong)能(neng)分(fen)別是：接(jie)地線(xian)(xian)(xian)(xian)(xian)(xian)（或者應(ying)該稱：接(jie)零(ling)線(xian)(xian)(xian)(xian)(xian)(xian)，接(jie)黑色(se)導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)）、讀數(shu)據(ju)(ju)線(xian)(xian)(xian)(xian)(xian)(xian)（信(xin)(xin)號出線(xian)(xian)(xian)(xian)(xian)(xian)，接(jie)綠色(se)導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)）、寫(xie)(xie)數(shu)據(ju)(ju)線(xian)(xian)(xian)(xian)(xian)(xian)（信(xin)(xin)號進線(xian)(xian)(xian)(xian)(xian)(xian)，接(jie)白色(se)導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)）、＋5V線(xian)(xian)(xian)(xian)(xian)(xian)（電源(yuan)正極，接(jie)紅(hong)色(se)導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)）。充(chong)電線(xian)(xian)(xian)(xian)(xian)(xian)一般為(wei)節(jie)約(yue)成本，會省(sheng)去(qu)中間的兩根(gen)線(xian)(xian)(xian)(xian)(xian)(xian)，即省(sheng)掉了讀數(shu)據(ju)(ju)線(xian)(xian)(xian)(xian)(xian)(xian)和寫(xie)(xie)數(shu)據(ju)(ju)線(xian)(xian)(xian)(xian)(xian)(xian)，也就(jiu)沒有(you)了數(shu)據(ju)(ju)讀寫(xie)(xie)能(neng)力，只具備手機充(chong)電功(gong)能(neng)。

因為(wei)充(chong)電(dian)(dian)(dian)線(xian)和(he)數據線(xian)的外觀(guan)幾乎(hu)一樣，所以電(dian)(dian)(dian)源(yuan)適配器廠家(jia)這里就要提醒大家(jia)在(zai)購買的時(shi)候千萬不要著了(le)道，把充(chong)電(dian)(dian)(dian)線(xian)當(dang)作了(le)數據線(xian)。
