Type-C 口(kou)(kou)(kou)對Type-C 口(kou)(kou)(kou)cc相通完整工(gong)作原理圖文詳解，Type-C 的(de)(de) CC1、CC2 引(yin)腳用于(yu) PD 設備識別(bie)，承(cheng)載(zai) USB-PD 的(de)(de)通信，引(yin)腳如果沒有(you)接(jie)(jie) 5.1kΩ 電(dian)(dian)(dian)(dian)(dian)阻接(jie)(jie)地(di)，那么(me)使(shi)用普通 AtoC 數(shu)據(ju)線(xian)(xian)依然是(shi)(shi)(shi)可(ke)以(yi)(yi)供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)，但(dan)如果使(shi)用 PD 充(chong)電(dian)(dian)(dian)(dian)(dian)器的(de)(de) CtoC 數(shu)據(ju)線(xian)(xian)供(gong)電(dian)(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)(dian)頭就(jiu)(jiu)會拒絕供(gong)電(dian)(dian)(dian)(dian)(dian)，對于(yu)Type-c耳(er)機取締3.5mm耳(er)機孔(kong)還有(you)一(yi)個原因就(jiu)(jiu)是(shi)(shi)(shi)基于(yu)Type-c接(jie)(jie)口(kou)(kou)(kou)本(ben)身的(de)(de)優越性。Type-c接(jie)(jie)口(kou)(kou)(kou)最(zui)顯眼的(de)(de)一(yi)個好處就(jiu)(jiu)是(shi)(shi)(shi)可(ke)以(yi)(yi)盲插。其次，就(jiu)(jiu)是(shi)(shi)(shi)傳輸(shu)(shu)數(shu)據(ju)快，供(gong)電(dian)(dian)(dian)(dian)(dian)功率(lv)高(gao)。TYPE-C插口(kou)(kou)(kou)的(de)(de)較(jiao)大(da)數(shu)據(ju)信息傳輸(shu)(shu)速(su)率(lv)可(ke)做(zuo)到10Gbit/秒(miao)，也(ye)就(jiu)(jiu)是(shi)(shi)(shi)USB3.1的(de)(de)規范。比之(zhi)前快20倍(bei)(bei)。Type-C運輸(shu)(shu)的(de)(de)輸(shu)(shu)出功率(lv)最(zui)大(da)達(da)到100W，而一(yi)般(ban)手機充(chong)電(dian)(dian)(dian)(dian)(dian)器是(shi)(shi)(shi)5V/1A，也(ye)就(jiu)(jiu)是(shi)(shi)(shi)只(zhi)有(you)5W。而按最(zui)大(da)功率(lv)100W一(yi)般(ban)算的(de)(de)話是(shi)(shi)(shi)目前普通手機充(chong)電(dian)(dian)(dian)(dian)(dian)功率(lv)的(de)(de)10倍(bei)(bei)。所以(yi)(yi)基于(yu)type-c接(jie)(jie)口(kou)(kou)(kou)的(de)(de)發(fa)展(zhan)，type-c耳(er)機取代3.5mm耳(er)機孔(kong)是(shi)(shi)(shi)水到渠成的(de)(de)事。
