Ikhebula le-VGA

I-Amzwire Enhle Ikhwalithi Intengo Ephansi 3+2 VGA Ikhebula Elijwayelekile le-VGA Male kuya ku-VGA Male
Izixhumi ze-VGA ezijwayelekile ze-15-Pin
Ikhebula le-VGA elijwayelekile elinamaphini ayi-15 empeleni libe yindlela engcono kakhulu yokuxhuma ama-monitor, ama-HDTV, noma ama-video splitter kuma-PC kokubili ukusetshenziswa kwasekhaya kanye nobungcweti. Lihambisana kabanzi futhi libe yinto ebalulekile embonini iminyaka eminingi, linikeza uxhumano oluthembekile lokudlulisa amasignali evidiyo ye-analog. Ngenkathi izixhumi ezintsha zedijithali ezifana ne-HDMI ne-DisplayPort sezivame kakhulu, amakhebula e-VGA asasetshenziswa kakhulu, ikakhulukazi ngemishini emidala noma ezimweni lapho ukuhambisana namadivayisi amadala kuyadingeka khona.
Ukuvikela Kathathu
Ikhebula le-VGA, eliyisixhumanisi esibalulekile phakathi kwama-monitor namakhompyutha, libonakala lihlukile ngendlela elakhiwe ngayo ngendlela eqinile kanye nomklamo walo osebenzayo. Lakhiwe ukuze likwazi ukumelana nezidingo zokusetshenziswa njalo, isimo salo siwusizo kakhulu njengoba sibonakala.
Emaphethelweni ayo kukhona izixhumi eziyi-15-pin eziphawulekayo, ezidumile ngombala wazo oluhlaza okwesibhakabhaka futhi ezinenjongo ekuhlelekeni kwazo. Lezi zixhumi, ezivame ukumbozwa nge-nickel ukuze ziqine futhi zimelane nokugqwala, zikhipha ukukhanya kwensimbi, okwengeza ubuhle bezimboni ekusebenzeni kwazo. Ukuphela okunombala wesiliva kwe-nickel plating akugcini nje ngokunikeza ubuhle obuhle kodwa futhi kuqinisekisa isikhathi eside lapho ubhekene nokuguguleka.
Ifakwe ngaphakathi kwejakethi eqinile kodwa eguquguqukayo, evame ukwenziwa nge-PVC, ingaphakathi lekhebula livikelwe ekuphazamisekeni kwangaphandle kanye nokucindezeleka kwemvelo. Nakuba umbala wejakethi ungahluka—imibala evamile ihlanganisa omnyama noma ompunga—isebenza njengesivikelo esivikelayo, ivikela izintambo ezithambile kanye nokuvikela ngaphakathi.
Ubuhlalu beFerrite
Izintambo ze-VGA ezinamakhanda afakwe i-nickel zinikeza ukuqina okuthuthukisiwe kanye nokumelana nokugqwala ngenxa ye-nickel plating, enikeza ungqimba oluvikelayo ezicini zemvelo kanye nokuguguleka ngokuhamba kwesikhathi. Indandatho yamagnetic, evame ukutholakala ihlanganiswe nezintambo ze-VGA, isebenza umsebenzi obalulekile ekugcineni ubuqotho besignali ngesikhathi sokudlulisa. Isebenza njengesihlungi esingasebenzi, ihlose futhi icindezele ukuphazamiseka kwe-electromagnetic frequency (EMI) kanye nokuphazamiseka kwe-radio-frequency (RFI) okungase kunciphise ikhwalithi yesignali ye-VGA. Ngokunciphisa umsindo ongafuneki kanye nama-harmonics, indandatho yamagnetic isiza ukuqinisekisa isignali ehlanzekile nezinzile, ikakhulukazi ezindaweni lapho ukuphazamiseka kwe-electromagnetic kuvame khona.
Ukuvikela Kathathu
Ukuvikela kathathu kuyisici esitholakala kwezinye izintambo, kufaka phakathi izintambo ze-VGA, okuhloswe ngazo ukunciphisa ukuphazamiseka kwe-radio-frequency (RFI) kanye nokuphazamiseka kwe-electromagnetic (EMI). Lokhu kuvikela kuqukethe izendlalelo eziningi zezinto zokuvikela ezizungeze izikhonkwane zekhebula, ngokuvamile ezenziwe ngethusi noma nge-aluminium, kanti isendlalelo ngasinye sengeza isithiyo esengeziwe ekuphazamisekeni kwangaphandle.
Ngokuba nokuvikela okuphindwe kathathu, ikhebula lihlinzeka ngokuvikelwa okuthuthukisiwe ngokumelene ne-RFI kanye ne-EMI, okuqinisekisa ukuthi isignali ihlala iqinile futhi ingaphazanyiswa ngisho nasekusebenzeni isikhathi eside kwekhebula. Lokhu kubaluleke kakhulu ezindaweni lapho kungase kube khona amadivayisi amaningi kagesi akhipha imisebe kagesi, okungase kwehlise ikhwalithi yesignali edluliselwa ngekhebula.
