Standard 15-Pin VGA zolumikizira
Chingwe chokhazikika cha 15-pini VGA chakhala chosankha cholumikizira zowunikira, ma HDTV, kapena zogawa makanema ku ma PC kuti azigwiritsa ntchito kunyumba ndi akatswiri. Ndiwogwirizana kwambiri ndipo yakhala yofunika kwambiri pamsika kwazaka zambiri, ikupereka kulumikizana kodalirika potumiza ma siginecha a analogi. Ngakhale mawonekedwe atsopano a digito monga HDMI ndi DisplayPort achulukirachulukira, zingwe za VGA zimagwiritsidwabe ntchito, makamaka ndi zida zakale kapena m'malo omwe kugwirizana ndi zida zoyambira ndikofunikira.
Kuteteza Katatu
Chingwe cha VGA, ulalo wofunikira kwambiri pakati pa oyang'anira ndi makompyuta, umakhala ndi mawonekedwe apadera opangidwa ndi kapangidwe kake kolimba komanso magwiridwe antchito. Wopangidwa kuti apirire zofuna zogwiritsidwa ntchito nthawi zonse, mawonekedwe ake ndi othandiza monga momwe amazindikirira.
M'malekezero ake muli chizindikiro cholumikizira mapini 15, owoneka bwino mumtundu wawo wabuluu komanso wopangidwa ndi cholinga. Zolumikizira izi, zomwe nthawi zambiri zimakutidwa ndi faifi tambala kuti zitheke kulimba komanso kukana dzimbiri, zimatulutsa chitsulo chonyezimira, zomwe zimawonjezera kukongola kwa mafakitale ku magwiridwe antchito awo. Kutsirizitsa kwa siliva kwa nickel plating sikungopereka kukongola kopukutidwa komanso kumapangitsa kuti moyo ukhale wautali pamaso pa kuwonongeka ndi kung'ambika.
Chokhala mkati mwa jekete yolimba koma yosinthika, yopangidwa kuchokera ku PVC, pachimake chingwecho chimatetezedwa ku kusokoneza kwakunja komanso kupsinjika kwa chilengedwe. Ngakhale mtundu wa jekete ukhoza kukhala wosiyana - mithunzi yodziwika bwino imakhala yakuda kapena imvi - imakhala ngati chotchinga choteteza, kuteteza mawaya osalimba ndi zotchingira mkati.
Mikanda ya Ferrite
Zingwe za VGA zokhala ndi mitu yokutidwa ndi faifi zimapereka kulimba komanso kukana dzimbiri chifukwa cha plating ya nickel, yomwe imapereka chitetezo ku zinthu zachilengedwe komanso kuvala pakapita nthawi. umphumphu pa nthawi yopatsirana. Imagwira ngati fyuluta yokhazikika, imayang'ana ndikupondereza kusokoneza kwa ma electromagnetic (EMI) ndi kusokoneza kwa radio-frequency (RFI) komwe kungathe kusokoneza mtundu wa chizindikiro cha VGA. Pochepetsa phokoso losafunikira ndi ma harmonics, mphete ya maginito imathandiza kuonetsetsa kuti chizindikirocho chizikhala choyera komanso chokhazikika, makamaka m'malo omwe kusokonezedwa ndi ma elekitiroma.
Kuteteza Katatu
Kuteteza katatu ndi gawo lomwe limapezeka mu zingwe zina, kuphatikiza zingwe za VGA, zomwe cholinga chake ndi kuchepetsa kusokoneza kwa radio-frequency (RFI) ndi kusokoneza kwamagetsi (EMI). Chotchingachi chimakhala ndi zigawo zingapo zotchingira zotchingira chingwe, zomwe nthawi zambiri zimapangidwa ndi mkuwa kapena aluminiyamu, ndipo gawo lililonse limawonjezera chotchinga chakunja.
Pokhala ndi zotchingira katatu, chingwechi chimapereka chitetezo chowonjezereka ku RFI ndi EMI, kuwonetsetsa kuti chizindikirocho chimakhalabe cholimba komanso chosasokonezedwa ngakhale pakuyenda kwanthawi yayitali. Izi ndizofunikira makamaka m'malo omwe pangakhale zida zambiri zamagetsi zotulutsa ma radiation a electromagnetic, zomwe zitha kutsitsa mtundu wa chizindikiro chomwe chimaperekedwa kudzera pa chingwe.
