Intambo yeVGA
01
Amewire Umgangatho oMkhulu ngexabiso eliphantsi 3 + 2 VGA Standard VGA Male to VGA Male Cable
I-Standard 15-Pin VGA Connectors
Intambo ye-VGA ye-15-pin eneneni ibe lukhetho lokukhetha ukuqhagamshela iimonitha, ii-HDTV, okanye izahluli zevidiyo kwiiPC kusetyenziso lwasekhaya kunye nobuchwephesha. Iyahambelana ngokubanzi kwaye ibiyeyona nto iphambili kwishishini iminyaka emininzi, ibonelela ngonxibelelwano oluthembekileyo lokuhambisa imiqondiso yevidiyo ye-analog. Ngelixa ujongano olutsha lwedijithali olunje nge-HDMI kunye ne-DisplayPort sele luxhaphakile, iintambo ze-VGA zisasetyenziswa ngokuqhelekileyo, ngakumbi ngezixhobo ezindala okanye kwiimeko apho ukuhambelana nezixhobo zelifa kuyimfuneko.
UkuKhusela kathathu
Intambo yeVGA, ikhonkco elibalulekileyo phakathi kweemonitha kunye neekhompyuter, inenkangeleko eyahlukileyo emiliselwe kulwakhiwo oluqinileyo kunye noyilo olusebenzayo. Yenzelwe ukunyamezela iimfuno zokusetyenziswa rhoqo, ifom yayo injenge-utilitarian njengoko ibonakala.
Emaphethelweni ayo kukho uphawu lweziqhagamshelo ze-15-pin, i-iconic kwi-hue yazo eluhlaza kunye nenjongo kuyilo lwazo. Ezi ziqhagamshelo, zihlala zifakwe nge-nickel ukwenzela ukomelela okuphuculweyo kunye nokumelana nomhlwa, zikhupha i-metallic sheen, zongeza umtsalane wobuhle beshishini ekusebenzeni kwazo. Ukugqitywa kwe-silver-toned ye-nickel plating ayiboleki nje ubuhle obukhazimlisiweyo kodwa ikwaqinisekisa ubomi obude ebusweni bokuguga nokukrazula.
Ifakwe ngaphakathi kwebhatyi eyomeleleyo kodwa ebhetyebhetye, eyenzelwe iPVC, undoqo wentambo ukhuselekile kuphazamiseko lwangaphandle kunye noxinzelelo lwendalo. Ngelixa umbala webhatyi unokwahluka-i-shades eziqhelekileyo ziquka ezimnyama okanye ezingwevu-zisebenza njengesithintelo sokukhusela, ukukhusela i-wiring ethambileyo kunye nokukhusela ngaphakathi.
Ferrite Amaso
Iintambo ze-VGA ezineentloko ze-nickel-plated zinika ukuqina okuphuculweyo kunye nokumelana nomhlwa ngenxa ye-nickel plating, enika umaleko okhuselayo kwizinto ezisingqongileyo kunye nokunxiba ngokuhamba kwexesha. ukunyaniseka ngexesha losulelo. Isebenza njengesihluzo sokwenziwa, ijolise kwaye icinezele ukuphazamiseka kwe-electromagnetic (EMI) kunye nokuphazamiseka kwerediyo-frequency (RFI) okunokuthi ngenye indlela kuthotywe umgangatho we-VGA uphawu. Ngokunciphisa ingxolo engafunekiyo kunye ne-harmonics, iringi yamagnetic inceda ekuqinisekiseni ucoceko kunye nomqondiso ozinzile ngakumbi, ngakumbi kwiindawo apho ukuphazamiseka kwe-electromagnetic kuxhaphakile.
UkuKhusela kathathu
Ukukhusela kathathu luphawu olufumaneka kwezinye iintambo, kubandakanywa iintambo zeVGA, ezijolise ekunciphiseni uphazamiseko lwerediyo-frequency (RFI) kunye nokuphazamiseka kwe-electromagnetic interference (EMI). Esi sikhuselo siqulathe iileya ezininzi zezinto ezikhuselayo ezijikeleze ii-conductor zentambo, ngokwesiqhelo zenziwe ngobhedu okanye nge-aluminiyam, kunye nomaleko ngamnye wongeza umqobo owongezelelweyo ngokuchasene nokuphazamiseka kwangaphandle.
Ngokukhusela kathathu, intambo ibonelela ngokhuseleko olongeziweyo ngokuchasene ne-RFI kunye ne-EMI, iqinisekisa ukuba isiginali ihlala yomelele kwaye ingaphazanyiswa nangaphezu kweentambo ezinde. Oku kubaluleke ngakumbi kwiindawo apho kunokubakho izixhobo zombane ezininzi ezikhupha imitha ye-electromagnetic, enokuthi ithobe umgangatho wophawu oluhanjiswa ngentambo.
