D-SUB isixhumi: ukubizwa, incazelo, ukuhlukaniswa kwedivayisi

I-D-SUB isixhumi saziwa cishe wonke umsebenzisi wekhompyutha yomuntu siqu. Yenzelwe ukuxhuma i-PC noma i-laptop ukuze izibukeli, ama-TV, njll. Isixhumi se-D-SUB (igama lesibili yi-VGA) sisekhona kuwo wonke amakhadi wevidiyo amakhompyutha, kodwa maduzane kwashintshwa ngesilinganiso esisha - i-interface ye-DVI. Noma kunjalo, lolu hlobo luvame ukugxilwa "kwe-iron endala".

Incazelo yesichazamazwi

I-D-SUB isikhangisi iqukethe pad nge izikhonkwane ezimbili, ezintathu noma ezine imigqa. Inombolo yezikhonkwane ezisemgqeni wokuqala ingaphezulu kwesinye. Oxhumene nabo bavikelwe ngesikhumba esithile esikhethekile sensimbi, iphrofayli yayo efana nokuma kwencwadi D. Ngenxa yalokhu, kungenzeka ukuthi ukuxhumeka okungalungile kwesikhangiso kungabandakanyi.

Izixhumi zalolu chungechunge (kokubili isixhumi ne-plug) zingaba nenani elihlukile loxhumana nabo:

1. Inombolo yezikhonkwane ezixhumene nezixhumi ezijwayelekile zihluka ezinyunithi ezingu-9 kuya ku-50.
2. Imikhiqizo ephakeme kakhulu inezixhumanisi ezingu-15 kuya kwabangu-78.
3. Amadivayisi we-Hybrid (izikhonkwane ezikhulisiwe) zingaba nezikhonkwane ezingu-3-43.

Njengomthetho, izixhumanisi ze-D-SUB (ukuxhumeka okuthembekile) zenzelwe ukucubungula okwengeziwe. Ngakho-ke, othintana nabo baleli divayisi bangafakwa ngophahla noma i-tin (tinning). Lesi sikhombimsebenzisi sifakwe kwi-block, ikhadi noma ikhebula. Esikhathini esilandelayo, kusetshenziselwa izinhlobo ezahlukene zokuhlala. Izixhumi ezinjalo zisetshenziselwa ukudluliswa kwedatha ezindaweni eziningi, kanye nokunikezela amandla kumadivaysi ahlukahlukene.

D-SUB isixhumi: ukuhlukaniswa

1. I-DB - yokuxubha. Isixhumi sinqwabelana ngekhebula ngokuhlunga. Bangabantu abengeziwe futhi abajwayelekile.
2. DC - ukuklolodela. Oxhumene nabo baqala ukugubungula kwikhebula, bese bafakwa kwigobolondo lesisangulo ngethuluzi elikhethekile.
3. I-di-tattoos yesitimela. Isixhumi sinqwabelana nge-pitch ye-1.27 mm nge-loop. Ubukhulu bedivayisi buyanda futhi buvamile.
4. I-DBI - ngokunyuka okusheshayo. Ama-cores wekhebula afakwa kumaxhumene we-connector, enesimo se- dovetail, futhi enamathele ngokufaka okukhethekile (kufakwe kuxhuma). Ukufaka umkhiqizo onjalo, ithuluzi elikhethekile lisetshenzisiwe.
5. I-DBC - hybrid (oxhumana nabo abengeziwe). Emzimbeni owodwa kunesignali (kusuka ku-4 kuya ku-1) namandla (kusukela ku-1 ukuya ku-8). Isixhumanisi esinjalo sivumela ukugcina isikhala kudivayisi, uma kudingekile ukusebenzisa izinhlobo ezahlukene zezibonakaliso. Lezi zixhumi ziphakanyiswe ebhodini ngokuhlunga. Isixhumi se-D-SUB (VGA) singaba nesakhiwo esihlukile esiteshini. Kulo xhumano, izinhlobo ezilandelayo zedivayisi ziyahlukaniswa:

• I-DRB - enezingqimba (i-right angle). Kunezinto ezintathu zokuguqula: A = 7.2 mm, B = 9.4 mm, C = 13.8 mm. Lezi zindinganiso zihambelana nebanga ukusuka emaphethelweni ohlangothini ukuya emgqeni wokuqala woxhumana nabo.
• I-DBB - ebonakalayo. Ngaphakathi kwesikhangiso kukhona izikhonkwane ze-cylindrical ezidayiswayo ebhodini.
• I-DRN - ihlangene (ihlangene). Amelela isakhiwo esisodwa, esinezixhumi ezimbili noma ezintathu ze-D-SUB ezinezinombolo ezahlukene zezikhonkwane. Usayizi we-compact we-connector ugcina isikhala kuma-PCB.

Izixhumanisi D-SUB MIL-C

Lolu hlobo lwesikhangisi lusetshenziselwa ukusebenzisa imishini yempi. Izixhumanisi ezinjalo zibhekwa njengamandla, zingafakwa ezinkambeni zobukhulu obuhlukahlukene. Kukhona ukuguqulwa okungena esikhundleni se-crimp terminals. Izixhumanisi zalolu chungechunge zibhekene nezidingo ezinamandla kakhulu zezici zobuchwepheshe. Zinezindlu ezinamandla kakhulu, eziphikisana nemithonya yemvelo. Lawa madivayisi ahlangabezana nezidingo eziphezulu zokuthembeka, kodwa ukusetshenziswa kwabo kunciphise kakhulu ngenxa yezindleko eziphezulu.
