Qhov txawv ntawm USB data cable thiab USB charging cable

USB ntaub ntawv cable lub luag haujlwm ntawm cov hlau:
Kab liab: Cov khoom fais fab zoo (khij rau kab: + 5V lossis VCC)
Dawb kab: Tsis zoo qhov muaj qhov tsis txaus siab cov ntaub ntawv (raws li: Data- or USB Port -)
Ntsuab kab: Qhov zoo ntawm cov ntaub ntawv kab hluav taws xob (raws li: Data + lossis USB Port +)
Dub kab: Hauv av (raws li: GROUND lossis GND).
Ntawm chav kawm, cov xim ntawm cov hlau yog tsuas yog nyob rau hauv lub stripping ntawm cov ntaub ntawv kab los yog sab sab ntawm lub charging kab thaum lub kua nplaum yuav pom.

Thaum pom ntawm lub taub hau ntawm USB lub taub hau ntawm lawv tus kheej, muaj kev sib txuas ntawm sab, ntawm sab laug mus rau sab xis, cov kov sib txuas ntawm cov dej num sib luag: Cov xaim av (los yog yuav tsum tau hais: xoom kab, ces dub xaim) , nyeem cov ntawv xov tooj (teeb liab, tom qab ntsuab xaim), sau cov ntaub ntawv xov tooj (teeb liab rau hauv kab, tom qab dawb xaim), +5 V kab (fais fab zoo, ces liab xaim).
Feem ntau, txhawm rau kom txuag tau cov nqi, cov nqi them nyiaj yuav tshem tawm qhov nruab nrab ntawm ob txoj kab, uas yog, kom txuag tau cov ntawv nyeem cov ntawv thiab sau ntawv cov kab (ntsuab thiab dawb kab), tsis muaj cov ntaub ntawv nyeem thiab sau tau ntawv tsuas them nyiaj xwb.
Tsis tas li ntawd, cov ntaub ntawv kab tuaj yeem yuav raug them, tus nqi them qis tsis tas yog thaum cov ntaub ntawv kab ua.
