Zolumikizira zamagetsi zimathandizira kuti pakali pano ziziyenda mozungulira dera lomwe latsekedwa kapena kudzipatula, zomwe zimathandiza kuti dera likwaniritse zomwe akufuna.Zolumikizira zina zili mu mawonekedwe a sockets wamba ndipo zimavomerezedwa ndikugwiritsidwa ntchito pamakampani opanga zingwe.
Zaka zambiri za chipwirikiti cholumikizira foni chomwe chikubwera, wopanga aliyense ali ndi njira zake komanso miyezo yake.National electronic distributors Association (NEDA, yomwe ndi NaTIonalElectronicDistributorsAssociaTIon) mu 1989 idapanga gulu lodziwika kuti cholumikizira zigawo encapsulation (LevelsofPackaging) mulingo wokhazikika.Malinga ndi muyezo uwu, zolumikizira zolumikizirana nthawi zambiri zimagwiritsa ntchito zolumikizira za Level 4.Komabe, mulingo umangogwiritsidwa ntchito pophunzira ndikugawa zolumikizira.Pantchito yothandiza, zolumikizira sizimatchulidwa kawirikawiri malinga ndi mulingo womwe uli pamwambapa, koma zimatchulidwa molingana ndi mawonekedwe a zolumikizira ndi mawonekedwe a kulumikizana (kutchulidwa kwa zolumikizira zamagetsi zamitundu yosiyanasiyana kumafotokozedwera mwatsatanetsatane mwatsatanetsatane wapadziko lonse lapansi) .Nthawi zambiri, zolumikizira zamitundu yosiyanasiyana zimakhala ndi magawo osiyanasiyana ogwiritsira ntchito.Kulumikizana kwa netiweki yolumikizirana nthawi zambiri kumadalira ma media omwe amagwiritsidwa ntchito, kotero zolumikizira nthawi zambiri zimakambidwa motengera njira zosiyanasiyana zolumikizirana, njira zolumikizirana, komanso kugwiritsa ntchito.
1. Multi-waya chingwe cholumikizira
Zolumikizira zingwe za Multiwire zimaphatikizapo zolumikizira za DB ndi DIX ndi zolumikizira za DIN.
(1) DB cholumikizira zikuphatikizapo DB-9, DB-15, DB-25 cholumikizira, ntchito kulumikiza siriyo doko zida ndi chingwe kufanana, ogaŵikana zabwino mapeto ndi mapeto oipa, DB25 mu DB akuimira D cholumikizira, chiwerengero. 25 imayimira chiwerengero cha cholumikizira singano.DB25 cholumikizira ndi gawo lodziwika bwino la microcomputer ndi mawonekedwe a mzere pakali pano.
(2) DIX cholumikizira: Choyimira chake chakunja ndi cholumikizira cha DB-15.Imalumikizidwa ndi slip, pomwe DB15 imalumikizidwa ndi screw ndipo nthawi zambiri imagwiritsidwa ntchito kulumikiza chingwe chakuda cha Efaneti.
(3) DIN cholumikizira: Pali singano zosiyanasiyana ndi makonzedwe a singano mu DIN cholumikizira, chimene chimagwiritsidwa ntchito kulumikiza Macintosh ndi AppleTalk maukonde.
2. Cholumikizira chopotoka
Malumikizidwe awiri opotoka amaphatikiza mitundu iwiri ya zolumikizira: RJ45 ndi RJ11.RJ ndi mawonekedwe omwe amafotokozera maukonde amtundu wapagulu.M'mbuyomu, mawonekedwe amtundu wa RJ ankagwiritsidwa ntchito m'kalasi 4, kalasi 5, super class 5, ndipo ngakhale posachedwapa adayambitsa mawaya a kalasi 6.
(1) RJ11 cholumikizira: ndi mtundu wa cholumikizira cha foni, chothandizira 2 waya ndi waya 4, zomwe zimagwiritsidwa ntchito polumikizira matelefoni.
(2) RJ45 cholumikizira: cholumikizira cha mtundu womwewo, mtundu wa jack, wokulirapo kuposa cholumikizira cha RJ11, ndikuthandizira mizere 8, chimadziwika kuti mawonekedwe a 8-bit modular, omwe amagwiritsidwa ntchito polumikiza awiri opotoka pamaneti.Chifukwa mabwalo omwe amagwiritsidwa ntchito ndi ma transmitter oyenerera komanso olandila, ali ndi kuthekera kwakukulu kokana.
Coaxial chingwe cholumikizira
Cholumikizira chingwe cha Coaxial chimaphatikizapo cholumikizira cha T ndi cholumikizira cha BNC ndi cholumikizira ma terminal.
(1) T cholumikizira: chimagwiritsidwa ntchito kulumikiza chingwe coaxial ndi cholumikizira cha BNC.
(2) BNC cholumikizira: BayoNette BayoNette mbiya cholumikizira, ntchito kulumikiza magawo maukonde ndi BNC cholumikizira.Kukula mwachangu kwamisika yolumikizirana ndi makompyuta komanso kuphatikiza kwaukadaulo wamakompyuta ndi kulumikizana kwakhala zinthu zazikulu zomwe zimalimbikitsa kukula kwa kufunikira kwa zolumikizira za coaxial.Chifukwa chingwe coaxial ndi t-cholumikizira zimadalira zolumikizira za BNC kuti zilumikizidwe, kotero msika wolumikizira wa BNC wamakampaniwo.
(3) ma terminals: zingwe zonse zimafunikira ma terminals, ma terminals ndi cholumikizira chapadera, ali ndi kukana kosankhidwa bwino kuti agwirizane ndi mawonekedwe a chingwe cha netiweki, chilichonse chomwe chiyenera kukhazikitsidwa.
(4) Mu heavy-cable Ethernet, zolumikizira zamtundu wa N zimagwiritsidwa ntchito nthawi zambiri.Malo ogwirira ntchito samalumikizidwa mwachindunji ndi netiweki ya Efaneti, koma amalumikizidwa ndi transceiver kudzera pa cholumikizira cha AUI (DIX cholumikizira).
Zolumikizira za Rf coaxial zimagawidwa m'mitundu itatu kuchokera kumtundu wolumikizira:
(1) Mtundu wolumikizana ndi ulusi: monga APC-7, N, TNC, SMA, SMC, L27, L16, L12, L8, L6 rf coaxial zolumikizira.Cholumikizira chamtunduwu chimakhala ndi mawonekedwe odalirika kwambiri komanso chitetezo chabwino, motero chimagwiritsidwanso ntchito kwambiri.
(2) Mtundu wolumikizira wa Bayonet: monga BNC, C, Q9, Q6 rf coaxial zolumikizira.Cholumikizira chamtunduwu chimakhala ndi mawonekedwe olumikizirana osavuta komanso othamanga, komanso ndikugwiritsa ntchito koyambirira kwa mawonekedwe a rf cholumikizira padziko lapansi.
(3) Direct pulagi ndi kankhani kugwirizana mtundu: monga SMB, SSMB, MCX, etc., mawonekedwe kugwirizana cholumikizira ali ndi makhalidwe a dongosolo yosavuta, yaying'ono, yaing'ono kukula, zosavuta miniaturize, etc.
Kuyankhulana kwa seri ndi njira yolumikizirana yomwe imagwiritsidwa ntchito kwambiri.Pakulumikizana kosalekeza, mbali zonse ziwiri zimafunika kugwiritsa ntchito mawonekedwe okhazikika.Zolumikizira za ISDN zoyambira zimatengera muyezo wa ISO8877.Muyezowu umapereka kuti cholumikizira cholumikizira cha S ndi RJ-45 (8 cores), ndipo ma cores apakati 4 ndi ma cores ogwira mtima.Chojambulira cha U sichiri chokhazikika, opanga ena amagwiritsa ntchito RJ-11, ena amagwiritsa ntchito RJ-45, amagwira ntchito pakati pa ma cores awiri.Chojambulira cha mawonekedwe a G.703 mu network transmission network nthawi zambiri BNC (75 ω) kapena RJ-45 (120 ω), ndipo nthawi zina mawonekedwe a 9-core amagwiritsidwa ntchito.Mafotokozedwe a USB (Universal Serial Bus) ndi Mulingo wolumikizira womwe umapereka cholumikizira wamba (mtundu A ndi mtundu B) kuti zotumphukira zonse za USB zilumikizidwe ku PCS.Zolumikizira izi zidzalowa m'malo mwa madoko osiyanasiyana akunja monga ma serial ports, madoko amasewera, madoko ofanana, ndi zina.
M'dera la mawaya okwanira, mitundu inayi yam'mbuyomu, mitundu isanu, mitundu isanu yapamwamba, kuphatikiza yomwe idangoyambitsidwa mumitundu isanu ndi umodzi ya waya, kugwiritsa ntchito mawonekedwe a RJ.Kuyambira ndi mitundu isanu ndi iwiri ya miyezo, ma cabling adagawidwa m'mbiri ya RJ ndi non-RJ interfaces.Cat7 cholumikizira chophatikizira (GG45-GP45) muyezo wakhala mogwirizana anatengera mu March 22, 2002 (IEC60603-7-7), kukhala 7 muyezo cholumikizira, ndipo akhoza yogwirizana kwathunthu ndi panopa RJ-45.
Kusankhidwa kwa cholumikizira magetsi kumaphatikizapo kugwiritsa ntchito zinthu zachilengedwe, magawo amagetsi, magawo amakina, kusankha kwa terminal.Zimaphatikizapo zofunikira zamagetsi zamagetsi, magetsi ovotera, oveteredwa panopa, kukana kukhudzana, chitetezo, magawo a chitetezo, magawo amakina, moyo wamakina, njira yolumikizira, mawonekedwe oyika ndi mawonekedwe, magawo a chilengedwe, mawonekedwe otsiriza ndi zina zotero.
