Dab tsi yog DC lub zog Jack, thiab dab tsi tseem ceeb ntawm cov tub ntxhais kawm ua si hauv cov khoom siv hluav taws xob

A DC lub zog nkausYog lub tshuab hluav taws xob tseem ceeb tsim los tsim kom muaj kev ruaj ntseg sib txuas ntawm kev hloov kho tshiab (DC)} {} {{{{{2} {voltage hluav taws xob. Feem ntau ua ke rau hauv lub cuab yeej cas ua, nws ua haujlwm raws li lub interface muaj siab xav uas lees txais ib qho kev xa khoom ntxiv, ua kom muaj txiaj ntsig zoo thiab txhim khu kev qha cov hwj huam.

Ntawm nws cov tub ntxhais, lub zog DC lub zog Jack ua raws li tus choj, txhais lub zog los ntawm lub zog hluav taws xob mus rau hauv daim ntawv siv tau los ntawm cov cuab yeej sab hauv circuitry. Nws cov qauv tsim ua ntej kev ruaj khov: Jack cov hlau sib cuag (feem ntau tooj liab lossis tooj dag lossis tiv thaiv kev tiv thaiv zoo thiab tiv thaiv kev tiv thaiv hluav taws xob. Qhov precision yog qhov kev sib txuas tsis tseem ceeb, tuaj yeem ua rau tsis zoo, overheating, lossis puas tsuaj rau cov khoom siv rhiab.

DC lub zog hluav taws xob Jack txuas xa mus rau cov ntsaws -} sab ntu uas ua khub nrog Jack. Cov txuas no yog engineed kom phim jack ntau thiab thiab kev teeb tsa (piv txwv li 5.5x1. Lo lus "DC lub zog fais fab" feem ntau siv sib pauv nrog "DC lub zog Jack," piav qhia txog cov khoom lag luam ruaj khov hauv cov cuab yeej uas tau txais cov txuas.

Los ntawm cov smartphones thiab lub laptop rau routers, koob yees duab, thiab ze txhua qhov DC - powered cov khoom siv rau cov khoom siv no. Lawv lub luag haujlwm txuas dhau mere kev sib txuas: lawv tswj hwm lub zog ntws, tiv thaiv kev tiv thaiv polarity (hauv qee cov qauv tsim), thiab tiv taus ntau yam kev siv. Tsis muaj DC lub zog Jacks, DC fais fab Jack Connectors, thiab DC hluav taws xob hauv nruab nrog {}}}}}}}}}}}}}}}}} Tsis tau lees tias lawv lub luag haujlwm tsis tseem ceeb hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob.
