Dab tsi yog Kev Ua Haujlwm thiab Kev Ua Haujlwm ntawm Lub Nplhaib Sib Nqus Ntawm Lub Computer Cable?
Apr 27, 2018| Peb feem ntau siv lub tshuab computer nrog lub nplhaib sib nqus ntawm cov ntaub ntawv kab txuas nrog lub vijtsam zaub. Nws yog sib npaug rau ib qho me me inductor, uas tuaj yeem tiv thaiv cov teeb liab induction generated los ntawm high-frequency electromagnetic radiation ntawm cov ntaub ntawv kab.
Lub nplhaib sib nqus ntawm cov ntaub ntawv kab yog tsuas yog tiv thaiv kev cuam tshuam.
1. Txhawm rau tiv thaiv kev cuam tshuam los ntawm qhov tam sim no surge thaum ntxig lossis tshem tawm cov hlau;
2. Tiv thaiv electromagnetic cuam tshuam hauv qhov chaw thiab ua rau kev sib kis tau ruaj khov. Lub motherboard, CPU, fais fab mov, thiab IDE cov ntaub ntawv cables nyob rau hauv lub computer chassis tag nrho cov ua hauj lwm nyob rau hauv high zaus, uas ua rau ib tug loj npaum li cas ntawm qhov chaw-borne spurious electromagnetic cuam cuam tshuam cov teeb liab nyob rau hauv lub chassis, thiab lub teeb liab zog yog ob peb zaug ntawm tus xov tooj sab nraud. lub chassis. kaum x! Lub USB cable tsis muaj lub nplhaib sib nqus tsis siv cov kev ntsuas tiv thaiv hauv qhov chaw no, tom qab ntawd cov kab USB no dhau los ua lub kav hlau txais xov zoo, tau txais txhua yam kev ntxhov siab ntau zaus hauv ib puag ncig ib puag ncig, thiab cov teeb liab no yog superimposed ntawm lub teeb liab kis tau los. Nws tseem yuav hloov cov teeb liab muaj txiaj ntsig uas tau kis los ntawm keeb kwm, thiab nws yuav ua rau muaj teeb meem.
Txhawm rau txhim kho kev sib kis tus nqi thiab kev ruaj ntseg, thiab txhawm rau txo qhov cuam tshuam ntawm cov kab sib kis mus rau lwm yam khoom siv, xws li suab phaib, cov txheej txheem tiv thaiv zoo li qub yog tsim. Cov txheej txheem tiv thaiv no yog ua los ntawm cov ntawv hlau nyias nyias lossis ntau cov xov tooj ntawm cov xov tooj zoo woven rau hauv cov duab mesh, thiab cov hauv paus ntsiab lus ntawm cov nyhuv saum npoo ntawm electrostatic teb yog siv. Ntawd yog, sab nrauv ntawm cov ntaub ntawv xa xov kab yog them nrog cov yeeb yaj kiab hlau, thiab cov txheej thaiv thaiv yog grounded rau lub chassis, kom cov ntaub ntawv kab tuaj yeem raug cais tawm ntawm qhov chaw cuam tshuam cov teeb liab.
Absorption magnetic nplhaib, tseem hu ua ferrite nplhaib, feem ntau siv nyob rau hauv detachable magnetic nplhaib. Nws yog ib qho uas nquag siv los tiv thaiv kev cuam tshuam hauv hluav taws xob circuits, thiab nws muaj kev cuam tshuam zoo rau lub suab nrov nrov. Feem ntau, cov khoom siv ferrite yog siv. Ua los ntawm (Mn-Zn). Lub nplhaib sib nqus muaj cov yam ntxwv impedance sib txawv ntawm ntau zaus. Feem ntau, qhov impedance ntawm qhov tsawg zaus yog tsawg heev. Thaum lub teeb liab zaus nce, lub impedance tshwm sim los ntawm lub nplhaib sib nqus nce sharply. Cov cim qhia ib txwm muaj thiab muaj txiaj ntsig tau dhau los zoo heev, thiab kev nkag mus ntawm cov teeb meem kev cuam tshuam ntau zaus tuaj yeem ua kom zoo, thiab tus nqi qis. Cov ntaub ntawv zoo tshaj plaws nrog cov nplhaib sib nqus muab cov khoom lag luam zoo dua, thiab cov khoom siv tsis zoo USB txo cov khoom lag luam.
Kuj tseem muaj lub nplhaib nqus, tseem hu ua lub nplhaib ferrite, uas feem ntau siv rau lub nplhaib sib nqus sib nqus. Nws yog ib qho uas nquag siv los tiv thaiv kev cuam tshuam hauv cov hluav taws xob hluav taws xob thiab muaj kev cuam tshuam zoo ntawm lub suab nrov nrov.
Yog li ntawd, nws tsis yog qhov xav tsis thoob tias peb txhua tus tab tom saib cov yas-hom sib nqus sib nqus rings ntawm cov kab teeb liab, cov kab txuas, thiab txawm tias high-end keyboards thiab nas.
