Uyini pinout-USB isixhumi

Universal-USB ibhasi ingenye ethandwa kakhulu kukhompyutha interface. Bona wangenela in 1997, futhi ngemva kweminyaka emithathu nje, ukuguqulwa entsha (2.0), ngesivinini by izikhathi 40 uma liqhathaniswa yasekuqaleni. Nokho, naphezu kwale ntuthuko, abakhiqizi waqaphela ukuthi ijubane akwanele ukusebenzisa yangaphandle kanzima ngemoto namanye amadivayisi ngesivinini. Futhi manje, entsha ye-USB esibonakalayo (uhlobo 3.0). Izinga entsha weqiwe ijubane inguqulo yangaphambilini (2.0) izikhathi 10. Lesi sihloko sigxile kakhulu udaba ezifana izabelo iphini-USB isixhumi. Lolu lwazi ingaba wusizo umsakazo nayizimfundamakhwela ngubani ngokuzimela wenza noma yiziphi-USB adaptha noma idivayisi kunikwe amandla nge-USB-ibhasi. Futhi, cabanga uyini pinout-micro-USB ye-USB uhlobo isixhumi, futhi mini-USB.

incazelo

hams Abaningi baye nenkinga uma port ngephutha exhunywe-USB ibhasi inikwa amandla yi-amandla omlilo fleshnakopiteley nemijikelezo. Ukuze ugweme izimo ezinjalo, kubalulekile ukuthi pinout-USB isixhumi iye yenziwa kahle, ngokuhambisana namazinga esamukelekile. Isixhumi hlobo USB 2.0 kuyinto isixhumi ayisicaba izikhonkwane ezine, it has AF (BF) esinelebuli - "mama" futhi AM (VM) - ". Ubaba" Micro-USB babe ilebula efanayo, kuphela Isiqalo micro, mini futhi uhlobo idivayisi, ngokulandelana, - Isiqalo mini. Eminyakeni emibili zinhlobo zehluke ejwayelekile 2.0 ngalolo lezi nezixhumi isetjentiswe 5 pin. Futhi ekugcineni, uhlobo lokugcina - lokhu USB 3.0. Ngaphandle, kubukeka sengathi uhlobo 2.0, kodwa Isixhumi ezinjalo kusetshenziswa kakhulu ngendlela 9 oxhumana.

Iphikhodi-uhlobo USB isixhumi

I-USB 2.0 wiring isixhumi simiswe ngalendlela lelandzelako:

- bentambo kuqala (umbala obomvu), isicelo kuso DC supply voltage +5 V;

- oxhumana yesibili (omhlophe), isetshenziselwa ngokudlulisa ulwazi (D-);

- ucingo lwesithathu (green), it is yaceba ukudlulisela ukwaziswa (D +);

- oxhumana wesine (umbala omnyama), it is fed supply voltage zero, kodwa ubizwa ngokuthi wire ezivamile.

Njengoba kakade kushiwo ngenhla, izinhlobo micro ne mini - ezinhlanu-pin ye-USB isixhumi. Wiring lokhu isixhumi nsé uhlobo 2.0, ngaphandle izikhonkwane lesine nelesihlanu. contact Okwesine (Lilac) - le-ID. Ngo uhlobo B nezixhumi ke aluhileli, + njengasosukwini lokungivivinya nezixhumi uhlobo A ukuvala wire ezivamile. Kugcine, esibulalayo yesihlanu (Black) - zero voltage.

Iphikhodi isixhumi USB- uhlobo 3.0

Eyokuqala oxhumana ezine ncamashí ejwayelekile 2.0, kubo thina ngeke siyeke. Oxhumana yesihlanu (blue) isetshenziswa ukuze adlulisele ulwazi nge USB3 minus (StdA_SSTX). isiphetho Sixth - into efanayo, kodwa uphawu lokwengeza (ophuzi). Seventh - earthing ezengeziwe. contact lesishiyagalombili (purple) ukwemukela imininingwane USB3 (StdA_SSRX) nge uphawu lokususa. Futhi ekugcineni, zinyanga eziyisishiyagalolunye (orange) - into efanayo yesikhombisa, kodwa uphawu.

kanjani Wiring-USB isixhumi wayeqamba?

Ukusetshenziswa ishaja nebhethri-USB isixhumi izintambo ezimbili kuphela: + 5V futhi contact ezivamile. Ngakho-ke, uma kudingeka solder ukuba 'ophethe "uhlobo isixhumi USB 2.0 noma 3.0, khona-ke kufanele usebenzise oxhumana lokuqala nesesine. Uma usebenzisa i-mini noma micro uhlobo, kuleso simo udinga fluster phezu ezikhumulweni kuqala futhi yesihlanu. Into ebaluleke kakhulu lapho amandla sisetshenziswa - ebona polarity zedivayisi.
