Intambo yeVGA

I-Amzwire Esemgangathweni Omkhulu Ixabiso Eliphantsi 3+2 VGA Standard VGA Male ukuya kwi-VGA Male Cable
Izihlanganisi zeVGA ezisemgangathweni zePin ezili-15
Intambo ye-VGA esemgangathweni ene-15-pin ibe yeyona ikhethwayo yokudibanisa iimonitha, ii-HDTV, okanye ii-video splitters kwiikhompyutha zokusetyenziswa ekhaya nakwingcali. Ihambelana kakhulu kwaye ibisoloko iyinto eqhelekileyo kushishino kangangeminyaka emininzi, inika uqhagamshelo oluthembekileyo lokudlulisa imiqondiso yevidiyo ye-analog. Nangona ii-interfaces ezintsha zedijithali ezifana ne-HDMI kunye ne-DisplayPort ziye zanda kakhulu, iintambo ze-VGA zisasetyenziswa rhoqo, ingakumbi kwizixhobo ezindala okanye kwiimeko apho kufuneka ukuhambelana nezixhobo ezindala.
Ukukhusela kathathu
Intambo yeVGA, edibanisa iimonitha kunye neekhompyutha, inembonakalo eyahlukileyo ebunjwe kukwakhiwa kwayo okuqinileyo kunye noyilo olusebenzayo. Yenzelwe ukumelana neemfuno zokusetyenziswa rhoqo, imo yayo iluncedo kakhulu njengoko ibonakala.
Kwicala layo kukho izihlanganisi ezineephini ezili-15, ezinombala oluhlaza okwesibhakabhaka kwaye zilungelelaniswe kakuhle. Ezi zihlanganisi, ezidla ngokugqunywa nge-nickel ukuze zihlale ixesha elide kwaye zikwazi ukumelana nokugqwala, zikhanyisa ngentsimbi, zongeza ubuhle bemizi-mveliso ekusebenzeni kwazo. Ukugqitywa kwe-nickel plating ene-silver-toned akupheleli nje ekunikeni ubuhle obucolekileyo kodwa kuqinisekisa ukuhlala ixesha elide xa kujongwe ukuguguleka.
Ifakwe ngaphakathi kwejakethi eqinileyo kodwa eguquguqukayo, edla ngokwenziwa ngePVC, umbindi wentambo ukhuselekile kuphazamiseko lwangaphandle kunye noxinzelelo lokusingqongileyo. Nangona umbala wejakethi unokwahluka—imibala eqhelekileyo ibandakanya umnyama okanye ungwevu—isebenza njengesithintelo sokukhusela, ikhusela iingcingo ezithambileyo kunye nokhuselo ngaphakathi.
Iintsimbi zeFerrite
Iintambo ze-VGA ezineentloko ze-nickel-plated zibonelela ngokuqina okuphuculweyo kunye nokumelana nokugqwala ngenxa ye-nickel plating, ebonelela ngomaleko okhuselayo kwiimeko zokusingqongileyo kunye nokuguguleka ngokuhamba kwexesha. Indandatho yemagnethi, edla ngokufunyanwa idityaniswe kwiintambo ze-VGA, isebenza umsebenzi obalulekileyo ekugcineni ukuthembeka kwesignali ngexesha lokudluliselwa. Isebenza njengesihluzo esingasebenziyo, ijolise kwaye icinezele ukuphazamiseka kwe-electromagnetic frequency (EMI) kunye nokuphazamiseka kwe-radio-frequency (RFI) okunokuthi ngenye indlela konakalise umgangatho wesignali ye-VGA. Ngokunciphisa ingxolo engafunekiyo kunye neeharmonics, indandatho yemagnethi inceda ukuqinisekisa isignali ecocekileyo nezinzileyo, ngakumbi kwiindawo apho ukuphazamiseka kwe-electromagnetic kuxhaphake khona.
Ukukhusela kathathu
Ukukhusela kathathu luphawu olufumaneka kwezinye iintambo, kuquka iintambo zeVGA, ezijolise ekunciphiseni ukuphazamiseka kwerediyo (RFI) kunye nokuphazamiseka kwe-electromagnetic (EMI). Olu khuselo luqulathe iileya ezininzi zezinto zokukhusela ezijikeleze ii-conductors zentambo, eziqhele ukwenziwa ngobhedu okanye i-aluminium, apho umaleko ngamnye wongeza umqobo owongezelelweyo nxamnye nokuphazamiseka kwangaphandle.
Ngokuba ne-triple shield, intambo inika ukhuseleko oluphuculweyo kwi-RFI kunye ne-EMI, iqinisekisa ukuba i-signal ihlala iqinile kwaye ingaphazanyiswa nokuba intambo isetyenziswa ixesha elide. Oku kubaluleke kakhulu kwiindawo apho kunokubakho izixhobo ezininzi ze-elektroniki ezikhupha i-electromagnetic radiation, enokuthi yonakalise umgangatho we-signal edluliselwa ngentambo.
