Kusankhidwa kwa zolumikizira za RF coaxial kuyenera kuganizira zonse zofunikira pakuchita komanso zinthu zachuma.Ntchitoyi iyenera kukwaniritsa zofunikira za dongosolo la zida zamagetsi.Pazachuma, iyenera kukwaniritsa zofunikira za uinjiniya wamtengo wapatali.Kwenikweni, mbali zinayi zotsatirazi ziyenera kuganiziridwa posankha zolumikizira.Kenako, tiyeni tione.
BNC cholumikizira
(1) Cholumikizira (SMA, SMB, BNC, etc.)
(2) Kuchita kwamagetsi, chingwe ndi msonkhano wa chingwe
(3) Fomu yochotsera (PC board, chingwe, gulu, etc.)
(4) Mapangidwe amakina ndi zokutira (zankhondo ndi zamalonda)
1, cholumikizira mawonekedwe
Cholumikizira cholumikizira nthawi zambiri chimatsimikiziridwa ndi kugwiritsa ntchito kwake, koma chiyenera kukwaniritsa zofunikira zamagetsi ndi zamakina nthawi imodzi.
Cholumikizira chamtundu wa BMA chimagwiritsidwa ntchito polumikizana ndi khungu lamagetsi otsika a microwave ndi ma frequency mpaka 18GHz.
Zolumikizira za BNC ndi zolumikizira zamtundu wa bayonet, zomwe zimagwiritsidwa ntchito kwambiri polumikizira ma RF ndi ma frequency otsika kuposa 4GHz, ndipo amagwiritsidwa ntchito kwambiri pamakina amtaneti, zida ndi magawo olumikizira makompyuta.
Kupatula screw, mawonekedwe a TNC ndi ofanana ndi a BNC, omwe amatha kugwiritsidwabe ntchito pa 11GHz ndipo amakhala ndi magwiridwe antchito abwino kwambiri pansi pamikhalidwe yogwedezeka.
SMA zolumikizira zomangira zimagwiritsidwa ntchito kwambiri muzandege, radar, kulumikizana kwa ma microwave, kulumikizana kwa digito ndi madera ena ankhondo ndi aboma.Kusokoneza kwake ndi 50 Ω.Mukamagwiritsa ntchito chingwe chosinthika, ma frequency ndi otsika kuposa 12.4GHz.Mukamagwiritsa ntchito chingwe chokhazikika, ma frequency apamwamba ndi 26.5GHz.75 Ω ili ndi chiyembekezo chogwiritsa ntchito kwambiri pakulankhulana kwa digito.
Voliyumu ya SMB ndi yaying'ono kuposa ya SMA.Kuti muyike chodzitsekera chokha ndikuwongolera kulumikizana mwachangu, kugwiritsa ntchito kwambiri ndi kulumikizana kwa digito, komwe kumalowetsa L9.50N yamalonda imakumana ndi 4GHz, ndipo 75 Ω imagwiritsidwa ntchito pa 2GHz.
SMC ndi yofanana ndi SMB chifukwa cha screw yake, yomwe imapangitsa kuti makina azigwira ntchito mwamphamvu komanso ma frequency angapo.Amagwiritsidwa ntchito makamaka m'malo ankhondo kapena kugwedera kwakukulu.
Cholumikizira cholumikizira chamtundu wa N chimagwiritsa ntchito mpweya ngati zotchingira zotsika mtengo, zotsekereza 50 Ω ndi 75 Ω, komanso pafupipafupi mpaka 11 GHz.Nthawi zambiri amagwiritsidwa ntchito pazida zam'madera, zofalitsa zofalitsa ndi zida zoyesera.
Zolumikizira za MCX ndi MMCX zoperekedwa ndi RFCN ndizocheperako komanso zodalirika polumikizana.Ndizinthu zomwe amakonda kuti zikwaniritse zofunikira zakuya komanso miniaturization, ndipo zimakhala ndi chiyembekezo chogwiritsa ntchito.
2, ntchito yamagetsi, chingwe ndi msonkhano wa chingwe
A. Kusokoneza: Cholumikizira chiyenera kufanana ndi kusokoneza kwa dongosolo ndi chingwe.Zindikirani kuti sizinthu zonse zolumikizira zomwe zimakumana ndi vuto la 50 Ω kapena 75 Ω, ndipo kusagwirizanaku kungayambitse kuwonongeka kwa machitidwe.
B. Voltage: onetsetsani kuti mphamvu yayikulu yolimbana ndi cholumikizira sichingadutse pakugwiritsa ntchito.
C. Mafupipafupi ogwirira ntchito: cholumikizira chilichonse chimakhala ndi malire ogwirira ntchito, ndipo mapangidwe ena amalonda kapena 75n amakhala ndi malire ochepera.Kuphatikiza pa ntchito zamagetsi, mtundu uliwonse wa mawonekedwe uli ndi mawonekedwe ake apadera.Mwachitsanzo, BNC ndi kugwirizana kwa bayonet, yomwe imakhala yosavuta kukhazikitsa komanso yotsika mtengo komanso yogwiritsidwa ntchito kwambiri pamagetsi otsika kwambiri;Mndandanda wa SMA ndi TNC umalumikizidwa ndi mtedza, kukwaniritsa zofunikira za malo ogwedezeka kwambiri pa zolumikizira.SMB ili ndi ntchito yolumikizana mwachangu ndikudula, kotero ndiyotchuka kwambiri ndi ogwiritsa ntchito.
D. Chingwe: Chifukwa chachitetezo chake chochepa, chingwe cha TV nthawi zambiri chimagwiritsidwa ntchito m'makina omwe amangoganizira za kulephera.Ntchito yodziwika bwino ndi mlongoti wa TV.
Chingwe chosinthika cha TV ndichosiyana ndi chingwe cha TV.Ili ndi mphamvu yopitilirabe komanso chitetezo chabwino.Ikhoza kupindika ndipo ili ndi mtengo wotsika.Amagwiritsidwa ntchito kwambiri pamakampani apakompyuta, koma sangathe kugwiritsidwa ntchito pamakina omwe amafunikira chitetezo chachikulu.
Zingwe zosinthika zotetezedwa zimachotsa inductance ndi capacitance, zomwe zimagwiritsidwa ntchito makamaka pazida ndi nyumba.
Flexible coaxial chingwe chakhala chingwe chofala kwambiri chotsekedwa chifukwa cha ntchito yake yapadera.Coaxial amatanthauza kuti siginecha ndi kondakitala grounding ali pa nkhwangwa chomwecho, ndipo kondakitala akunja amapangidwa ndi waya wabwino woluka, choncho amatchedwanso kuluka coaxial chingwe.Chingwe ichi chimakhala ndi chitetezo chabwino pa chowongolera chapakati ndipo chitetezo chake chimadalira mtundu wa waya woluka komanso makulidwe a wosanjikiza woluka.Kuphatikiza pa kukana kwamagetsi apamwamba, chingwechi ndi choyeneranso kugwiritsidwa ntchito pafupipafupi komanso kutentha kwambiri.
Zingwe zolimba zolimba m'malo mwake zimalowetsa zipolopolo za tubular, zomwe zimapangitsa kuti pakhale vuto losatchinga bwino la zingwe zoluka pama frequency apamwamba.Zingwe zolimba kwambiri zimagwiritsidwa ntchito pama frequency apamwamba.
E. Kusonkhana Chingwe: Pali njira ziwiri zazikulu zopangira cholumikizira: (1) kuwotcherera kokondakita yapakati ndikupukuta wosanjikiza wotchinga.(2) Kudula kokondakita chapakati ndi chotchinga chotchinga.Njira zina zimachokera ku njira ziwiri zomwe zili pamwambazi, monga kuwotcherera kondakitala chapakati ndi crimping wosanjikiza chishango.Njira (1) imagwiritsidwa ntchito pazinthu zopanda zida zapadera zoyika;Chifukwa chakuchita bwino kwambiri komanso kudalirika kwa kutha kwa njira yolumikizira crimping, komanso mapangidwe a chida chapadera cha crimping amatha kuwonetsetsa kuti gawo lililonse la mphutsi lomwe lasonkhanitsidwa ndilofanana, ndikupanga chida chotsika mtengo cholumikizira, chotchinga chotchinga cha crimping. wa kondakitala wa malo owotcherera adzakhala otchuka kwambiri.
3, Kuthetsa fomu
Zolumikizira zitha kugwiritsidwa ntchito pazingwe za RF coaxial, matabwa osindikizira ndi njira zina zolumikizirana.Zochita zatsimikizira kuti cholumikizira chamtundu wina chimafanana ndi chingwe chamtundu wina.Nthawi zambiri, chingwe chokhala ndi m'mimba mwake chaching'ono chakunja chimalumikizidwa ndi zolumikizira zazing'ono za coaxial monga SMA, SMB ndi SMC.4, Makina kapangidwe ndi ❖ kuyanika
Mapangidwe a cholumikizira adzakhudza kwambiri mtengo wake.Mapangidwe a cholumikizira chilichonse amaphatikizapo mulingo wankhondo ndi muyezo wamalonda.Muyezo wankhondo umapanga mbali zonse zamkuwa, zotsekemera za polytetrafluoroethylene, ndi zokutira golide zamkati ndi zakunja malinga ndi MIL-C-39012, ndikuchita kodalirika kwambiri.Kapangidwe kazamalonda kamagwiritsa ntchito zida zotsika mtengo monga kuponyera mkuwa, kutsekemera kwa polypropylene, zokutira zasiliva, ndi zina.
Zolumikizira zimapangidwa ndi mkuwa, mkuwa wa beryllium ndi chitsulo chosapanga dzimbiri.Kondakitala wapakati nthawi zambiri amakhala wokutidwa ndi golide chifukwa cha kutsika kwake, kukana kwa dzimbiri komanso kusatulutsa mpweya wabwino.Miyezo yankhondo imafuna plating ya golide pa SMA ndi SMB, ndi plating ya siliva pa N, TNC ndi BNC, koma ogwiritsa ntchito ambiri amakonda kupaka faifi tambala chifukwa siliva ndiosavuta kuyimitsa.
Zolumikizira zolumikizira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo polytetrafluoroethylene, polypropylene ndi polystyrene yolimba, yomwe polytetrafluoroethylene imakhala ndi ntchito yabwino kwambiri yotchinjiriza koma mtengo wokwera kwambiri.
Zakuthupi ndi kapangidwe ka cholumikizira zimakhudza zovuta zogwirira ntchito komanso magwiridwe antchito a cholumikizira.Chifukwa chake, ogwiritsa ntchito ayenera kusankha cholumikizira chomwe chimagwira bwino ntchito komanso kuchuluka kwamitengo malinga ndi malo awo ogwiritsira ntchito.
