Chingwe cha VGA
01
Chingwe cha Amzwire cha mamita 15 cha 1080p VGA (3+6) Chachimuna mpaka Chachimuna Nick Plated (DAE) HD Video Connector cha Pulojekiti ya PC ya TV
Chingwe cha VGA 3+6, chomwe chimadziwikanso kuti cholumikizira cha VGA kapena chingwe, chimagwira ntchito ngati cholumikizira pakati pa kompyuta kapena chipangizo china cholumikizidwa ndi VGA ndi chowunikira chowonetsera, pulojekitala, kapena chophimba cha wailesi yakanema. Dzina la "3+6" nthawi zambiri limatanthauza mawonekedwe a pini ya cholumikizira cha VGA, kusonyeza mapini 9 okonzedwa m'mizere iwiri, ndi mapini atatu pamzere umodzi ndi mapini 6 pamzere wina. Chingwechi chimapangitsa kuti zizindikiro za kanema wa analog zifalitsidwe, zomwe zimathandiza kuwonetsa zithunzi ndi zithunzi pazenera lolumikizidwa. Chimathandizira ma resolution mpaka ma pixel 1920x1200 ndipo chimagwiritsidwa ntchito kwambiri powonetsa zotsatira za kompyuta, monga mawonetsero, makanema, ndi mapulogalamu ogwiritsa ntchito zithunzi zambiri.
PVC (Polyvinyl Chloride) ndi chinthu chopangidwa ndi zinthu zambiri komanso chogwiritsidwa ntchito kwambiri chomwe chimadziwika kuti ndi cholimba, chotsika mtengo, komanso chosinthasintha. Chopangidwa ndi chlorine, kaboni, ndi haidrojeni, PVC imalimbana kwambiri ndi kusweka, mankhwala, kuzizira, ndi malawi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Kusinthasintha kwake kumalola kuti ipangidwe mosavuta m'mawonekedwe ndi kukula kosiyanasiyana, ikugwiritsidwa ntchito kwambiri pomanga, mapaipi, kutchinjiriza magetsi, zizindikiro, zinthu zachipatala, ndi ma phukusi. Ngakhale kuti pali nkhawa za momwe imakhudzira chilengedwe komanso kutulutsa zinthu zoopsa panthawi yopanga ndi kutaya, kugwiritsa ntchito PVC kwambiri kukupitirirabe chifukwa cha mtengo wake wotsika, moyo wautali, komanso kusinthasintha m'mafakitale osiyanasiyana.
CCS (Copper-Clad Steel) imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, makamaka pakulankhulana ndi zamagetsi. Zinthu zopangidwa ndi chitsulo chopangidwa ndi mkuwa, zomwe zimapangitsa kuti pakhale mgwirizano pakati pa kuyendetsa bwino magetsi ndi mphamvu. Mukulankhulana, CCS imagwiritsidwa ntchito kwambiri mu zingwe za coaxial potumiza zizindikiro pamtunda wautali popanda kutaya chizindikiro. Kulimba kwake kumapangitsa kuti ikhale yoyenera kuyika panja ndi pansi pa nthaka. Kuphatikiza apo, CCS imapeza ntchito popanga zamagetsi, komwe imapereka njira zina zotsika mtengo m'malo mwa ma conductors amkuwa oyera popanda kusokoneza magwiridwe antchito. Ponseponse, CCS imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti ma signal atumizidwa bwino komanso kulumikizana m'makina amakono olumikizirana.
Mphete ziwiri zamaginito, zomwe nthawi zambiri zimagwiritsidwa ntchito m'mabwalo amagetsi ndi zingwe, zimathandiza kwambiri kuchepetsa kusokonezeka kwa maginito (EMI) ndi kusokonezeka kwa ma radio frequency (RFI). Zili ndi mphete ziwiri zamaginito zomwe zimayikidwa kumbuyo ndi kumbuyo, zimapanga dera lotsekedwa la maginito lomwe limaletsa bwino kuwala kosafunikira kwa maginito. Mwa kuyamwa ndi kutulutsa mphamvu zamaginito, mphete ziwiri zamaginito zimaletsa kusokonezeka kuti kusokoneze zigawo zamagetsi ndi zizindikiro, kuonetsetsa kuti magwiridwe antchito abwino komanso odalirika. Ukadaulo uwu umagwiritsidwa ntchito kwambiri m'magwiritsidwe osiyanasiyana, kuphatikiza magetsi, zingwe za data, ndi zida zamawu/kanema, komwe kusunga umphumphu wa chizindikiro ndikofunikira kwambiri. Ponseponse, mphete ziwiri zamaginito zimagwira ntchito yofunika kwambiri pakukweza kugwirizanitsa kwa maginito ndi kuchepetsa kusokonezeka kwa chizindikiro m'makina amagetsi.
