Zolumikizira za VGA za Ma Pin 15 Zokhazikika
Chingwe cha VGA cha ma pin 15 chakhala chisankho chogwiritsidwa ntchito kwambiri polumikiza ma monitor, ma HDTV, kapena ma vidiyo splitter ku ma PC kuti agwiritsidwe ntchito kunyumba komanso pantchito. Chimagwirizana kwambiri ndipo chakhala chofunikira kwambiri mumakampani kwa zaka zambiri, chikupereka kulumikizana kodalirika potumiza ma signal a kanema wa analog. Ngakhale ma interfaces atsopano a digito monga HDMI ndi DisplayPort afala kwambiri, ma waya a VGA amagwiritsidwabe ntchito, makamaka ndi zida zakale kapena pamene kuli kofunikira kuti zigwirizane ndi zida zakale.

Chingwe cha VGA, chomwe chimagwirizanitsa ma monitor ndi makompyuta, chili ndi mawonekedwe apadera chifukwa cha kapangidwe kake kolimba komanso kapangidwe kake kogwira ntchito. Chopangidwa kuti chikhale cholimba komanso chogwiritsidwa ntchito nthawi zonse, mawonekedwe ake ndi othandiza kwambiri monga momwe chimadziwikira.
Kumapeto kwake kuli zolumikizira za mapini 15, zodziwika bwino mu mtundu wawo wabuluu komanso zokhala ndi cholinga m'mapangidwe awo. Zolumikizira izi, zomwe nthawi zambiri zimakutidwa ndi nickel kuti zikhale zolimba komanso kuti zisawonongeke, zimawala ndi chitsulo, zomwe zimapangitsa kuti ntchito yawo ikhale yokongola kwambiri. Kumapeto kwa nickel plating yokhala ndi siliva sikuti kumangopangitsa kuti ikhale yokongola komanso kumatsimikizira kuti idzakhalapo kwa nthawi yayitali ngakhale itawonongeka.
Chokhala mkati mwa jekete lolimba koma losinthasintha, lomwe nthawi zambiri limapangidwa kuchokera ku PVC, pakati pa chingwecho pamakhala chotetezedwa ku zosokoneza zakunja ndi zovuta zachilengedwe. Ngakhale kuti mtundu wa jeketeyo umasiyana—mithunzi yodziwika bwino imakhala yakuda kapena imvi—imateteza mawaya ndi zotchingira mkati.
Mikanda ya Ferrite
Zingwe za VGA zokhala ndi mitu yophimbidwa ndi nickel zimapereka kulimba komanso kukana dzimbiri chifukwa cha nickel plating, yomwe imapereka chitetezo ku zinthu zachilengedwe komanso kuwonongeka pakapita nthawi. Mphete ya maginito, yomwe nthawi zambiri imapezeka mu zingwe za VGA, imagwira ntchito yofunika kwambiri pakusunga umphumphu wa chizindikiro panthawi yotumiza. Imagwira ntchito ngati fyuluta yosagwira ntchito, imayang'ana ndikuletsa kusokonezedwa kwa maginito amagetsi okwera pafupipafupi (EMI) ndi kusokonezedwa kwa maginito a wailesi (RFI) komwe kukanatha kuwononga mtundu wa chizindikiro cha VGA. Mwa kuchepetsa phokoso losafunikira ndi ma harmonics, mphete ya maginito imathandiza kutsimikizira chizindikiro choyera komanso chokhazikika, makamaka m'malo omwe kusokonezedwa kwa maginito kumafala.

Kuteteza katatu ndi chinthu chomwe chimapezeka mu zingwe zina, kuphatikizapo zingwe za VGA, zomwe cholinga chake ndi kuchepetsa kusokoneza kwa ma radio-frequency (RFI) ndi kusokoneza kwa electromagnetic (EMI). Kuteteza kumeneku kumakhala ndi zigawo zingapo za zinthu zotetezera kuzungulira ma conductor a chingwecho, zomwe nthawi zambiri zimapangidwa ndi mkuwa kapena aluminiyamu, ndipo gawo lililonse limawonjezera chotchinga chowonjezera ku kusokoneza kwakunja.
Popeza chingwechi chili ndi zotchingira zitatu, chimapereka chitetezo chowonjezereka ku RFI ndi EMI, kuonetsetsa kuti chizindikirocho chikhale cholimba komanso chosasokonezedwa ngakhale chingwecho chikuyenda kwa nthawi yayitali. Izi ndizofunikira kwambiri m'malo omwe pangakhale zida zambiri zamagetsi zomwe zimatulutsa kuwala kwamagetsi, zomwe zitha kuwononga mtundu wa chizindikiro chomwe chikutumizidwa kudzera mu chingwecho.
