iindaba

Izixhumi zombane zenza ukuba i-current ihambe kwisekethe apho ivaliwe okanye ibekwe yodwa, eyenza ukuba isiphaluka sifezekise umsebenzi ojoliswe kuwo.Ezinye izihlanganisi zikwimo yeesokethi eziqhelekileyo kwaye zamkelwe ngokubanzi kwaye zisetyenziswa kushishino lweentambo.

Iminyaka emininzi yesiphithiphithi sokuhlela umnxeba ongenayo, umenzi ngamnye uneendlela zakhe zokuhlela kunye nemigangatho.Umbutho kazwelonke wabasasazi be-elektroniki (NEDA, eyi-NaTIonalElectronicDistributorsAssociaTIon) ngo-1989 uphuhlise isethi eyaziwa ngokuba yi-connector components encapsulation (LevelsofPackaging) umgangatho wohlelo.Ngokwalo mgangatho, izihlanganisi zonxibelelwano ngokuqhelekileyo zisebenzisa izihlanganisi zenqanaba lesi-4.Nangona kunjalo, inqanaba lisetyenziselwa ukufunda nokwahlulahlula izihlanganisi.Kumsebenzi osebenzayo, iziqhagamshelo azifane zibhengezwe ngokwale nqanaba lingasentla, kodwa zithiywe ngokwendlela yenkangeleko yeziqhagamshelo kunye nolwakhiwo loqhagamshelo (ukuthiywa kwamagama eziqhagamshelo zombane zeefomu ezahlukeneyo zesakhiwo kucaciswa yingcaciso ebanzi yamazwe ngamazwe) .Ngokuqhelekileyo, izihlanganisi zezakhiwo ezahlukeneyo zineendlela ezahlukeneyo zokusetyenziswa.Uqhagamshelo lwenethiwekhi yonxibelelwano luhlala luxhomekeke kumajelo asetyenziswayo, ngoko ke iziqhagamshelo zidla ngokuxoxwa ngokwemixholo yemidiya eyahlukeneyo, iindlela zonxibelelwano, kunye neemeko zesicelo.

1. Isidibanisi sentambo yeentambo ezininzi
Izixhumi zentambo ezininzi ziquka i-DB kunye ne-DIX izixhumi kunye nezixhumi ze-DIN.
(1) Isidibanisi seDB siquka iDB-9, DB-15, DB-25 isinxibelelanisi, sisetyenziselwa ukuqhagamshela isixhobo se-serial port kunye nentambo enxuseneyo, yahlulwe yaba yisiphelo esihle kunye nesiphelo esibi, iDB25 kwiDB imele iD isinxibelelanisi, inani. I-25 imele inani leenaliti zokudibanisa.I-DB25 isidibanisi yinxalenye eqhelekileyo ye-microcomputer kunye nojongano lomgca okwangoku.
(2)Isidibanisi se-DIX: Ukumelwa kwayo kwangaphandle sisidibanisi se-DB-15.Idityaniswe ne-slip, ngelixa i-DB15 idityaniswe ne-screw kwaye isoloko isetyenziselwa ukudibanisa kwintambo enzima ye-Ethernet.
(3) Isixhumi se-DIN: Kukho iinaliti ezahlukeneyo kunye nokulungelelaniswa kweenaliti kwidibansi ye-DIN, esetyenziswa ngokuqhelekileyo ukudibanisa i-Macintosh kunye ne-AppleTalk networks.

2. Isidibanisi esijijekileyo
Udibaniso lwesibini olujijekileyo lubandakanya iindidi ezimbini zeziqhagamshelo: i-RJ45 kunye ne-RJ11.RJ yi-interface echaza uthungelwano lonxibelelwano loluntu.Ngaphambili, i-interfaces yohlobo lwe-RJ yayisetyenziswa kwiklasi yesi-4, iklasi yesi-5, iklasi enkulu yesi-5, kwaye kwangoku nje yaziswa i-wiring yeklasi yesi-6.
(1) i-RJ11 isinxibelelanisi: luhlobo lwesinxibelelanisi somgca wefowuni, oluxhasa i-2 i-wire kunye ne-4 i-wire, ngokuqhelekileyo isetyenziselwa ukufikelela kumgca wefowuni yomsebenzisi.
(2) i-RJ45 isinxibelelanisi: isidibanisi sohlobo olufanayo, uhlobo lwe-jack, olukhulu kune-RJ11 isinxibelelanisi, kunye nenkxaso yemigca ye-8, ngokuqhelekileyo eyaziwa ngokuba yi-8-bit interface yemodyuli, esetyenziselwa ukudibanisa isibini esijijekileyo kwinethiwekhi.Ngenxa yokuba iisekethe ezisetyenzisiweyo zi-balanced transmitter kunye ne-receiver, inekhono eliphezulu lokwaliwa kwemodi eqhelekileyo.

Isidibanisi sentambo ye-coaxial
Isidibanisi sentambo ye-coaxial ibandakanya isinxibelelanisi se-T kunye nesinxibelelanisi se-BNC kunye ne-terminal resistor.
(1) Isidibanisi seT: sisetyenziselwa ukudibanisa intambo ye-coaxial kunye nesixhumi se-BNC.
(2) Isixhumi se-BNC: I-BayoNette BayoNette umbhobho wokudibanisa, esetyenziselwa ukudibanisa amacandelo enethiwekhi kwi-THE BNC connector.Ukukhula okukhawulezayo konxibelelwano kunye neemarike zekhompyuter kunye nokudityaniswa konxibelelwano kunye nobuchwepheshe bekhompyuter kube zizinto eziphambili ezikhuthaza ukukhula kwemfuno yezihlanganisi ze-coaxial.Ngenxa yokuba intambo ye-coaxial kunye ne-t-connector ixhomekeke kwi-BNC izixhumi zokudibanisa, ngoko ke imarike yokudibanisa i-BNC yoshishino.
(3) iitheminali: iintambo zonke zifuna iitheminali, iitheminali zingumdibaniso okhethekileyo, unokumelana okukhethiweyo ngokucokisekileyo ukuhambelana neempawu zentambo yomnatha, nganye kufuneka isekelwe.
(4) Kwi-ethernet ye-heavy-cable, i-N-type connectors isetyenziswa rhoqo.Indawo yokusebenza ayiqhagamshelwanga ngokuthe ngqo kuthungelwano lwe-Ethernet, kodwa iqhagamshelwe kwi-transceiver nge-AUI connector (DIX connector).

Izixhumi ze-coaxial ze-RF zahlulwe zaba ziindidi ezintathu ukusuka kuhlobo lonxibelelwano:
(1) Uhlobo loqhagamshelwano olunemisonto: njenge-APC-7, N, TNC, SMA, SMC, L27, L16, L12, L8, L6 rf coaxial connectors.Olu hlobo lwesinxibelelanisi luneempawu zokuthembeka okuphezulu kunye nesiphumo esihle sokukhusela, ngoko ke sesona sisetyenziswa kakhulu.
(2) Uhlobo loqhagamshelo lweBayonet: njenge-BNC, C, Q9, Q6 rf coaxial connectors.Olu hlobo lwesiqhagamshelo luneempawu zoqhagamshelo olulula nolukhawulezayo, kwaye sesona sicelo sokuqala sefom yoqhagamshelo lwe-rf emhlabeni.
(3) Iplagi echanekileyo kunye nohlobo lokudibanisa i-push: njenge-SMB, i-SSMB, i-MCX, njl., le fomu yokudibanisa ikhonkco ineempawu zesakhiwo esilula, i-compact, ubungakanani obuncinci, kulula ukuyi-miniaturize, njl.
Unxibelelwano olulandelelanayo lusetyenziswa ngokubanzi imo yonxibelelwano.Kunxibelelwano olulandelelanayo, omabini amacala kufuneka asebenzise ujongano oluqhelekileyo.Izihlanganisi ze-ISDN zojongano olusisiseko zisebenzisa umgangatho we-ISO8877.Umgangatho ubonelela ukuba i-S interface standard connector yi-RJ-45 (8 cores), kunye ne-middle 4 cores yi-cores esebenzayo.Isidibanisi se-U asiyiyo umgangatho, abanye abavelisi basebenzisa i-RJ-11, abanye basebenzisa i-RJ-45, basebenza kakuhle phakathi kweentsimbi ezimbini.Umdibaniso we-G.703 ujongano kwinethiwekhi yothumelo lwedijithali ngokuqhelekileyo i-BNC (75 ω) okanye i-RJ-45 (120 ω), kwaye ngamanye amaxesha i-9-core interface isetyenziswa.Ukucaciswa kwe-USB (i-Universal Serial Bus) ngumgangatho woxhulumaniso obonelela ngesiqhagamshelo esiqhelekileyo (uhlobo A kunye nohlobo B) kuzo zonke iiperipherals ze-USB ukudibanisa kwi-PCS.Ezi ziqhagamshelo ziya kuthatha indawo yamazibuko ahlukeneyo emveli angaphandle afana namazibuko othotho, amazibuko emidlalo, amazibuko ahambelanayo, njl.
Kwindawo yocingo olubanzi, iintlobo ezine zangaphambili, iindidi ezintlanu, iintlobo ezintlanu, ezibandakanya nje ukuqaliswa kwiintlobo ezintandathu ze-wiring, ukusetyenziswa kwe-RJ interface.Ukuqala ngeentlobo ezisixhenxe zemigangatho, i-cabling ngokwembali yahlulwe yaba yi-RJ kunye ne-non-RJ interfaces.I-Cat7 idibaniso yokudibanisa (i-GG45-GP45) umgangatho wamkelwe ngazwi linye ngo-Matshi 22, 2002 (IEC60603-7-7), ube ngumdibaniso oqhelekileyo we-7, kwaye unokuhambelana ngokupheleleyo ne-RJ-45 yangoku.
Ukukhethwa kwesixhumi sombane kubandakanya ukusetyenziswa kweemeko zokusingqongileyo, iiparitha zombane, iiparitha zomatshini, ukukhethwa kwe-terminal.Ibandakanya iimfuno zeparamitha yombane, i-voltage elinganisiweyo, i-current rated, i-contact resistance, ukukhusela, i-parameters yokhuseleko, i-parameters ye-mechanical, ubomi bomatshini, imodi yokudibanisa, imodi yokufakela kunye nokuma, iiparitha zokusingqongileyo, i-terminal mode njalo njalo.
