Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov xov hlau hauv USB cable
Txheem
Hauv "universal serial bus" lossis USB, muaj plaub lub xov hlau, uas feem ntau yog xim liab, ntsuab, dawb, thiab dub. Txhua ntawm cov xov hlau no muaj cov teeb liab sib xws lossis ua haujlwm. Kev txheeb xyuas qhov zoo thiab qhov tsis zoo yog qhov tseem ceeb thaum ua haujlwm nrog lawv.
Txawm hais tias muaj ob qhov zoo thiab tsis zoo nyob rau hauv tag nrho, txhua tus muaj qhov sib txawv.
Hauv tsab xov xwm no, peb yuav nyob ntawm cov xov hlau no kom ntxaws ntxiv.
Txhua ntawm plaub lub xov tooj ntawm USB cable ua li cas?
Ib qho ntawm feem ntau siv cov chaw nres nkoj thiab kev sib txuas lus raws tu qauv ntawm cov khoom siv yog USB lossis Universal Serial Bus. Lub hom phiaj ntawm USB yog los tswj cov chaw nres nkoj uas lub computer accessories xws li tshuab luam ntawv thiab cov keyboards txuas nrog. Koj tuaj yeem pom cov kev xaiv chaw nres nkoj ntawm gadgets xws li xov tooj ntawm tes, scanners, koob yees duab, thiab game controllers uas sib txuas lus nrog cov tswv. (1)
Thaum koj qhib USB cable, koj tuaj yeem pom plaub xim sib txawv ntawm USB xov hlau: liab thiab dub rau lub zog, dawb thiab ntsuab rau cov ntaub ntawv, thiab lwm yam. Qhov zoo xaim nqa 5 volts yog liab; cov hlau tsis zoo, feem ntau hu ua av xaim, yog xim dub. Muaj ib daim duab pinout rau txhua hom kev sib txuas ntawm USB; cov no yog cov hlau me me hauv cov khoom sib txuas uas siv los nkag rau txhua qhov ntawm cov cables thiab lawv txoj haujlwm.
USB cable xim thiab lawv txhais li cas
| Hlau xim | qhia |
| Liab hlau | Qhov zoo fais fab cable muab 5 volts DC. |
| dub kab | Hauv av lossis tsis zoo lub zog xaim. |
| Dawb hlau | Cov ntaub ntawv zoo hlau. |
| Ntsuab hlau | Cov ntaub ntawv tsis zoo. |
Lwm yam USB cable hlau xim specifications
Hauv qee cov hlua USB, koj tuaj yeem pom ntau qhov sib txuas ntawm cov xim hlau, suav nrog txiv kab ntxwv, xiav, dawb, thiab ntsuab.
Lub ntsiab txhais ntawm qhov zoo lossis qhov tsis zoo ntawm cov xov hlau hauv cov qauv xim no txawv. Hauv qhov no, koj yuav tsum xyuas cov lus hauv qab no:
| Hlau xim | qhia |
| Txiv kab ntxwv | Qhov zoo fais fab cable muab 5 volt DC zog. |
| Dawb hlau | Hauv av lossis tsis zoo lub zog xaim. |
| xiav kab | Cov ntaub ntawv tsis zoo. |
| Ntsuab hlau | Cov ntaub ntawv zoo hlau. |
Hom ntawm USB cables
Muaj ntau hom USB, thiab cov txheej txheem ntawm USB cable txiav txim siab ceev npaum li cas nws tuaj yeem hloov cov ntaub ntawv. Piv txwv li, USB 2.0 chaw nres nkoj tuaj yeem hloov cov ntaub ntawv mus txog 480 Mbps, thaum USB 3.1 Gen 2 chaw nres nkoj tuaj yeem hloov cov ntaub ntawv ntawm 10 Mbps. Koj tuaj yeem siv cov lus hauv qab no kom nkag siab qhov ceev thiab nta ntawm txhua hom USB:
| USB hom | Nws puas tuaj yeem ua yeeb yaj kiab? | Nws puas tuaj yeem muab lub zog? | Baud tus nqi |
| USB 1.1 | Tsis | Tsis | 12 Mbps. |
| USB 2.0 | Tsis | Yog | 480 Mbps. |
| USB 3.0 | Yog | Yog | 5 Gbps ib |
| USB 3.1 | Yog | Yog | 10 Gbps ib |
Cov lus nug nquag nug
Dab tsi ua rau USB-C txawv ntawm USB li niaj zaus?
Piv nrog rau USB-A, uas tsuas tuaj yeem ua haujlwm txog li 2.5W thiab 5V, USB-C tuaj yeem yooj yim tuav 100W thiab 20V rau cov khoom siv loj dua. Pass-through charging - yeej yog USB hub uas ua rau lub laptops thiab them lwm yam khoom siv tib lub sijhawm - yog ib qho ntawm cov txiaj ntsig zoo.
Cov kab ntsuab thiab dawb puas tseem ceeb?
Cov xov hlau zoo-tsis zoo yog cov kab tseem ceeb tshaj plaws. Paub txog cov xim dab tsi ntawm cov hluav taws xob hluav taws xob no yog qhov tseem ceeb vim tias lawv yog qhov tseem ceeb rau kev siv hluav taws xob rau koj cov khoom siv.
USB cable puas tuaj yeem faib thiab txuas?
Koj tuaj yeem ua koj tus kheej USB cables los ntawm kev txiav thiab splicing uas twb muaj lawm cables mus rau qhov ntev thiab connector hom koj xav tau. Tsuas yog cov cuab yeej uas xav tau rau cov txheej txheem no yog cov hlau txiav thiab cov kab xev hluav taws xob, txawm hais tias cov hlau soldering thiab cov cua sov shrink tubing tuaj yeem siv los txhim kho qhov zoo ntawm cable.
