Micro USB-connectors. Hom ntawm USB-connectors, lawv nta

Cov hauj txheej txheem tsis yog nyob rau hauv qhov chaw. Tam sim no cov qauv ntawm cov ntau yam ntawm cov pab kiag li lawm yog sib txawv heev los ntawm lawv laus laus counterparts. Nws hloov tsis tau tsuas yog lawv cov tsos thiab nrog cov khoom, tab sis kuj txoj kev txuas xyuas hauv computer thiab roj teeb chargers. Yog hais tias muaj ntau yam xov tooj thiab txawm koob yees duab tsis tau muaj xws li ib lub sij hawm yog tseem 5-7 xyoo dhau los. Tab sis, thaum lub caij txhua txhua ib cov ntaus ntawv yuav ua kev cob cog rua rau ib tug PC los yog laptop. Xov tooj, neeg uas ua ntawv, smartphone, ntsiav tshuaj, video recorder, neeg uas ua ntawv los yog lub koob yees duab - tag nrho cov yog nruab nrog connectors uas tso cai rau koj mus cuag lawv mus rau lwm pab kiag li lawm.

Tab sis, raws li yog ib qho yooj yim mus saib, plug connector yog cov sib txawv. Thiab yuav nrog lub xov tooj qaum rau ib co yog vim li cas yuav siv tsis tau nyob rau hauv nrog koj nyiam neeg uas ua ntawv. Raws li ib tug tshwm sim, sau ib Rev ntawm cables, koj yog lossi tsis meej pem nyob rau hauv lawv thiab cia li tsis to taub yog vim li cas nws yog yooj yim sua kom ib tug tib hlau no yog tsim rau kev twb kev txuas ntawm tag nrho cov pab kiag li lawm. Tab sis raws li koj paub, nws tsis tshwm sim. Txawm tias tam sim no muaj ntau dua los yog tsawg ib tug standard connector, yam tsawg kawg rau smartphones, cov xov tooj thiab cov ntsiav tshuaj. Thiab nws lub npe - micro-USB. Yuav ua li cas yog qhov txuj ci no thiab yuav ua li cas nws ua hauj lwm, peb yuav piav qhia txog nram qab no.

Micro USB-connector: yog dab tsi?

Ob tug ntawm cov feem ntau nrov nyob rau hauv lub sij hawm tas los qhov - qhov no mini thiab micro-USB. Lawv cov npe hais lus rau lawv tus kheej. Qhov no yog ib tug me me thiab cov tswv yim tsim, uas yog siv nyob rau hauv me me cov pab kiag li lawm kom tseg tau chaw, thiab tejzaum nws rau ib tug ntau elegant tsos. Piv txwv li, ib tug micro-USB connector yog yuav luag 4 lub sij hawm tsawg tshaj rau ib tug ntsiav tshuaj tshaj ib tug txheej txheem USB 2.0., Tab sis muab hais tias tus ntaus ntawv nws tus kheej yog ib feem ntawm ib tug tus kheej lub computer los yog ib tug laptop, qhov kev xaiv no yog zoo meej. Tab sis muaj ib co nuances. Piv txwv li, los ntawm cov loj ib tug yuav tsis ua tsawg dua li, yog li cov micro-USB connectors tsis tau hloov txawm nyob rau hauv lub mini-USB. Txawm tias nyob rau hauv tej rooj plaub qhov rov qab tus txheej txheem yog siv tau. Thiab cov kev hloov ntawm lub micro-USB nrog lawv ob txhais tes yog tsis zoo li mus xaus nrog ib yam dab tsi zoo. Painfully hniav nyiaj hniav kub yog ua hauj lwm. Nyob rau hauv tas li ntawd, lo lus "micro" cov lus dag ntau hom connectors, thiab qhov no yuav tsum nco ntsoov. Tshwj xeeb tshaj yog yog hais tias koj sim mus yuav ib tug tshiab cable. Micro-USB ntawm koj cov ntsiav tshuaj tej zaum yuav tsis tau tshaj cov connector nyob rau thaum xaus ntawm lub cable uas koj yuav.

hom

Micro-USB connectors yuav tsum muaj ob tug sib txawv kiag li hom. Lawv muaj sib txawv tau thiab, thiaj li, lawv zoo sib txawv. Tus thawj hom yog hu ua ib tug micro-USB 2.0. Hom B - nws yog siv raws li lub neej ntawd ntaus ntawv yog vneglasnym txheem rau qhov tseeb qauv ntawm smartphones thiab ntsiav tshuaj, vim li no, nws yog heev heev thiab yuav luag txhua leej txhua tus nyob rau hauv tsev muaj tsawg kawg yog ib tug micro-USB 2.0 cable. hom B.

Qhov thib ob hom - micro-USB 3.0 - cov ntaub ntawv connectors rau cov phiaj yog tsis ntsia, tab sis yuav tshwm sim nyob rau hauv smartphones thiab handsets ntawm ib co hom. Feem ntau cov feem ntau lawv yog siv los equip lwm nyuaj drives.

zoo

Lub ntsiab zoo uas muaj micro-USB connectors rau cov ntsiav tshuaj, yuav tsum tau ntshai li ib tug ntau dua kev ceev thiab txhim khu kev qha Symptoms plug. Tab sis qhov no fact los ntawm tsis muaj txhais tau tias cais tau ib tug teeb meem no nrog cov Cheebtsam. Cov uas keev ua breakage yuav lam ua tswv lawv tus kheej cov pab kiag li lawm. Sudden taw, ntog ntsiav tshuaj thiab xov tooj rau hauv pem teb los yog txawm lub asphalt, tshwj xeeb tshaj yog nyob rau sab qhov twg lub connector nws tus kheej, los mus txhim kho ib yam dab tsi nrog lawv tus kheej txhais tes tsis muaj qhov tsim nyog paub - cov no yog cov tseem ceeb yog vim li cas vim uas txawm lub feem ntau cov khoom ib feem ntawm USB-ports tawm down. Tab sis nws tshwm sim hais tias qhov no tshwm sim vim hnav lub ntaus ntawv, siv tsis raws cai los yog Hoobkas tsis xws luag.

Cov uas keev ua malfunction los yog los ua rau lawv tus kheej lub micro-USB connector, los yog nyob ib sab thiab kev cob cog rua rau lawv nyob rau hauv kom meej lub saw. Rau tej txog tej tswv ntawm nws hloov - ib tug teeb meem ntawm feeb, tab sis nyob rau hauv lub tsev nrog rau qhov no thiaj lis tsis txhua leej txhua tus. Yog hais tias koj tseem xav li cas nws yog ua tau yuav kho cov micro-USB connector pinout (los yog, nyob rau hauv lwm yam lus, cov pin hauj lwm) - tus txheej txheem yog tsis ntev heev thiab tsis yooj yim, yog tias koj txoj kev ua nws nrog lub siab thiab tus yam ua ntej kev nyeem ntawv ntawm cov ntaub ntawv. Ib tug ob peb lub tswv yim yuav tsum muab hauv qab no.

Connector micro-USB: pinout

Raws li yog lub npe hu, nrog rau li ib txwm ports thiab connectors, txhua yam yog yooj yim - koj tsuas yuav tau muab ib daim duab ntawm pem hauv ntej ntawm lub connector, tab sis nyob rau hauv daim iav duab, thiab solder. Nrog USB mini- thiab micro-hom yog tag nrho cov sib txawv me ntsis. Lawv connectors muaj 5 hu, tab sis nyob rau hauv lub hom connector nyob rau hauv kev sib cuag nrog tus naj npawb 4 yog tsis siv, thiab ntaus A nws yog kaw rau GND, uas ranked thib tsib.

Lub "ob txhais ceg» micro-USB connector

Txij li thaum feem ntau niaj hnub micro-ntsiav tshuaj yog cov USB, liab xwb tsis rau them, tab sis kuj yuav synchronize, vim hais tias ntawm qhov ntau heev siv ntawm qhov teeb meem nrog nws muaj ntau ntau connector.

Yog li ntawd, raws li hais saum toj no, cov pa micro-USB connector muaj tsib "ob txhais ceg". Ib tug saum toj no zero, nyob rau ntawm tsib volts thiab rho tawm ib tug. Lawv yog cov nyob rau txawv sab ntawm lub connector thiab, raws li, yuav tsis raug kev txom nyem thaum sib cais los ntawm motherboard. Tsuas yog ib tug "ceg" connector, uas yog feem ntau so nrog ncoo ntau yam kev kawm rau koj hnav. Nws yog situated ze rau qhov rho tawm "ceg". Yog hais tias cov kev sib cuag lawm, tus ntaus ntawv yuav tsis raug them. Hais tias yog, lub kaw lus yuav saib lub hwj huam mov, tab sis lub teeb uas them txheej txheem yuav tsis muab qhov chaw.

Qhov seem ob "ob txhais ceg" yog lub luag hauj lwm rau cov sij hawm poob, uas yog, upload los yog download tau cov duab, suab paj nruag, thiab lwm yam Lawv ua li no nyob rau tib lub sij hawm, yog li ib tug kis yuav ua nyob rau hauv lub txiav ntawm lub thib ob.

Paub qhov muaj nuj nqi ntawm "ob txhais ceg", koj yuav tau los mus txiav txim, vim lub divergence ntawm cov neeg uas koj tau muaj teeb meem thiab cov uas sawv daws yuav koj yuav tsum tau solder rov qab mus rau koj cov ntsiav tshuaj "nyob rau hauv lub system."

Qhov yuav tshwm ntawm tsis yog hloov connector

Tsis soldered micro-USB, tus tswv feem ntau fim cov nram qab no txoj kev sib tw:

1. Luv-Circuit Court fais fab mov, yog hais tias lawv yog soldered inverted hom.
2. Ntsiav tshuaj txiav txim seb tus them qaum, tab sis lub roj teeb (rechargeable roj teeb) yog tsis them.
3. ntsiav tshuaj roj teeb yog them fine, tab sis nws tsis sync nrog koj lub computer los yog laptop.
4. Cov ntsiav tshuaj no ua hauj lwm kom zoo, tab sis tej zaum "zoo li" koj yuav tsum coj nws mus rau hauv lub khw, tsis txhob solder koj tus kheej (piv txwv li, cov coupons qhov yuav tsis pib tam sim ntawd tom qab txoj siav, los yog tej zaum lub qaum koj yuav tsum tshem tawm thiab ntxig dua ob peb zaug ua ntej them pib) .

Lub neej yav tom ntej ntawm lub micro-USB

Vim qhov no yog ib qho ntawm feem nrov rau hnub tim ports, Yog hais tias koj kawm tau los hloov lawv ib zaug no kev txawj yuav pab tau koj nyob rau hauv lub neej yav tom ntej ntau heev. Thiab txawm yog hais tias lawv yuav tsis muab rau ib tug "kub txheej txheem" nyob rau hauv txoj kev loj hlob ntawm cov xov tooj thiab lwm yam cov pab kiag li lawm. Thiab peb tseem yuav tsum muaj ib tug tag nrho sau los ntawm nyob ntawm tej rau laptop lub Acer, rau cov xov tooj ntawm Samsung, rau kua iPad thiab cov koob yees duab lub Nikon, tab sis active siv cov micro-connectors muab kev cia siab, tsis ntev, es tsis txhob "pob paj" peb muaj nyob rau hauv lub txee yuav yuav raws li nyob rau hauv ib tug micro-USB cable uas yog haum rau ntawm yam tsawg kawg 90% ntawm cov khoom nyob rau hauv lub tsev.
