Anthu nthawi zambiri amadabwa posankha cholumikizira chabwino cha BNC. Amafuna kudziwa magawo ogwirira ntchito ndi malo ogwiritsira ntchito.
BNC imadziwika kuti ndi imodzi mwama RF coaxial interfaces. Imawonetsedwa pamakonzedwe owonera makanema, zida zolumikizirana, makina owulutsira, zida zoyesera, ndi ntchito zosonkhanitsira ma sign a mafakitale.
M'mapulojekiti enieni, mafotokozedwe, zida, kulepheretsa, ndi zomangamanga za BNC harness zimapanga kusiyana kwakukulu kuti ziwonetsetse ntchito. Mainjiniya amakumana ndi nkhaniyi nthawi zonse. Zolumikizira za BNC zikuwoneka zofanana poyang'ana koyamba. Komabe ena amapereka zizindikiro zomveka bwino komanso zokhazikika. Zina zimabweretsa zovuta zosokoneza.
Chidutswa ichi chimadutsa pazigawo zazikulu za zida zolimba za BNC. Imakhudza kapangidwe kake, magawo a magwiridwe antchito, zosankha zama chingwe, malo ogwiritsira ntchito, ndi malangizo kwa mainjiniya posankha yoyenera.
Mapangidwe Oyambira a BNC Harness. Zigawo zake zazikulu zikuphatikizapo zotsatirazi.
Cholumikizira cha BNC chimabwera ngati pulagi kapena jack. Mtundu wamphongo uli ndi bayonet yakunja ya bayonet. Yaikazi ili ndi kagawo kagawo. Kutseka mwachangu komanso kukana kugwedezeka kumawerengera ngati mphamvu zazikulu za BNC.
Insulator imagwiritsa ntchito zinthu za PTFE. Imagwira kukana kutentha ndikusunga kukhazikika kwa chizindikiro.
Kondakitala wapakati amakhala ngati pini yokhala ndi matheminali-okutidwa ndi golide. Izi zimachepetsa kutayika ndikuletsa oxidation.
Chophimbacho chimapereka chitetezo chachitsulo. Imapondereza kusokoneza ndipo imagwira ntchito ndi EMI.
Chingwe cha coaxial chimagwira ntchito yapakati. Zake zimakhudza kuchepetsedwa, mtundu wazithunzi, komanso kutalika kwa ma signature.
Zokhazikika Zokhazikika za BNC Harnesses. Kusiyanitsa pakati pa Mabaibulo kumagwira ntchito m'njira zingapo.
Impedans imapanga kusiyana kwakukulu apa. Mtundu wa 75 ohm umagwirizana ndi kuwunika kwamavidiyo ndi zosowa zowulutsa. Zimatengera kusankha kofala kwambiri. Mtundu wa 50 ohm umagwirizana ndi zida zolumikizirana komanso zoyesera.
Zosokoneza zosagwirizana zimayambitsa zithunzi zosawoneka bwino, mitundu yakuda, kapena kutayika kwa ma siginecha.
Mapangidwe a cholumikizira amawasankha kukhala mitundu yowongoka ya BNC. Bent BNC imagwira ntchito bwino m'malo olimba. Panel BNC imagwira ntchito yokweza zida. BNC yopanda madzi imagwira ntchito zowunikira panja.
Mtundu wa chingwe umasweka kwambiri. RG59 imatsogolera pakuwunika kwamavidiyo ambiri. RG6 imagwiritsa ntchito maulendo aatali-atali. RG58 imagwirizana ndi kulumikizana komanso kugwiritsa ntchito ma frequency a wailesi. 3C2V ndi 5C2V kuwerengera ngati zingwe zodzitetezera. Zingwe zapadera zotsika{12}}zimaloleza kuzisintha mwamakonda anu.
Njira zopangira zimasiyanasiyananso. Masitayilo ophwanyidwa amapereka kukhazikika komanso kukwanira kupanga zochuluka. Zogulitsa zimalola kusintha makonda. Mabaibulo opangidwa ndi jekeseni amapereka kukhazikika kwakukulu kwa zinthu zakunja.
Kuphatikizika kwa madoko kumaphatikizapo BNC wamwamuna kupita ku BNC wamwamuna. Ena amapita ku BNC amuna kupita ku BNC akazi. Ena amasakaniza BNC ndi RCA. Zosankha zina zowonjezera BNC ndi SMA, N, kapena UHF.
Kuwonongeka kwa Parameter ya Performance. Zomangira -zapamwamba za BNC zimafunikira luso linalake.
Kukhazikika kwa impedance ndikofunikira kwambiri. Makanema ogwiritsa ntchito 75 ohm. Kukhazikitsa kwa RF kumamatira ku 50 ohm. Kupatuka kwazing'ono kumatanthauza zizindikiro zokhazikika.
Attenuation imasankha kumveka kwa chizindikiro ndi mtunda wotumizira.
VSWR, kapena stand wave ratio, ikuwonetsa digiri yofananira. Zomangira zapamwamba zimafika pamlingo wa mfundo imodzi kapena kuchepera.
Mulingo wotchingira umabwera ndi-nsanjika imodzi, zoluka ziwiri{1}}zosanjikiza, kapena tepi yoluka kuphatikiza ndi zojambulazo. Kutchinjiriza kolimba kumateteza mawonekedwe a chipale chofewa, mikwingwirima, ndi kusokoneza kwaphokoso.
Kukana kutentha ndi kukana kupindika kumagwira ntchito zazikulu. Kuyang'anira panja kumafuna kuzizira mpaka madigiri makumi awiri Celsius. Imafunikanso chitetezo cha dzuwa ku kuwala kwa UV. Kugwedezeka kumathandizira-kugwedezeka kwanthawi yayitali.
Zochitika Zogwiritsira Ntchito BNC Harnesses. Kufananiza zofananira ndi mafakitale ndizomveka.
Machitidwe owonetsera mavidiyo ndi omwe amagwiritsidwa ntchito kwambiri. Amalumikiza makamera, amadyetsa zolowetsa za VCR, ndikulumikizana ndi zida zowonetsera. Kukhazikitsa komwe kumakonda kumaphatikiza 75 ohm yokhala ndi chingwe cha RG59.
Kuwulutsa ndi kupanga makanema kumadalira zida za SDI. Machitidwe akukhamukira amoyo amapindulanso. Apa, 75 ohm yokhala ndi-chingwe chotchinga chocheperako chimagwira ntchito bwino kwambiri.
Kuyesa ndi zida kumaphatikizapo ma oscilloscopes, magwero azizindikiro, ndi ma probe oyesa. Njira-yosankha ndi 50 ohm ndi RG58.
Zida zoyankhulirana ndi kufalitsa ma siginecha akumafakitale zimakonda chingwe cha 50 ohm chotetezedwa ndi coaxial.
-ma adapter amtundu amatha kuthana ndi zosowa zosakanizidwa. BNC kupita ku SMA, BNC kupita ku RCA, kapena BNC mpaka N mitundu yowunikira ndi kulumikizana.
Malangizo Osankha Mainjiniya. Baibulo lothandizali likukhudza milandu wamba.
Makamera owunikira amayitanitsa 75 ohm BNC yokhala ndi RG59.
Kutumiza mtunda wautali-kupitirira mamita zana kumafunika 75 ohm BNC ndi RG6.
Oscilloscopes ndi zida zasayansi zimayendera 50 ohm BNC yokhala ndi RG58.
Kunja kumafunika mitundu yopangidwa ndi jakisoni yosalowa madzi yokhala ndi zingwe ziwiri-zotetezedwa.
Mipata yopapatiza yokhala ndi njira yachingwe yonyenga imapindula ndi BNC yopindika.
Zolumikizira -zida zimagwiritsa ntchito BNC kupita ku SMA kapena BNC kupita ku RCA.
Mwachidule, chingwe choyenera cha BNC chimatsika kuti chikonze zolepheretsa, zingwe zofananira, ndi chitetezo choyenera.
