Kodi chojambulira BNC n'chiyani?

Coaxial kawirikawiri mauthenga a BNC amatchulidwa ndi mayina a opanga, alinjini Paul Neal ndi Karl Conselman. Dzina lonse ndi "Bayonet Nile - Conselman". Liwu lakuti "bayonet" la chiyambi cha French limatanthauzanso bayonet. Chojambulira chimatseka kugwiritsa ntchito loko, yomwe inali pamfuti ya bayonets.

BNC wothandizira amalola kuigwiritsa ntchito mu maulendo ndi magetsi mpaka 500 V ndi mafupipafupi mpaka 3 GHz (wavelength 10 cm). Mitsinje iwiri yozungulira imagwiritsidwa ntchito: 50 ndi 75 Ohm. Ngati BNC chojambulira Amagwiritsidwa ntchito ndi chingwe choyenera, ndipo kutsutsana kwawo kumagwirizana, ndiye kutayika pa mgwirizanowu sikudutsa 0.3 dB.

Chingwe cha coaxial chingwe nthawi zambiri Yangokhala 8mm. Zinthu zakuthandizirana ndizitsulo ndi siliva kapena golide. Mzere wotsekemera umapangidwa ndi zinthu zomwe zili ndi otsika kwambiri dielectric imfa: fluoroplastic kapena polystyrene.

Komanso BNC solder connector Ziyenera kukhala ndi kutsekemera kwa madzi. Polystyrene idzasungunuka panthawi ya soldering, mbali yayikulu idzachoka pambali yake, ndipo chogwirizanitsa chidzakhala chosatheka.

Pofuna kupewa kutayika kwa chingwe, SARMATT imapanga zolumikiza, mapeto ake omwe ali ndi kasupe wotetezeka. Izi zimatsimikizira kuchuluka kwa zosokoneza ndi ma connections kuposa 500.

Ogwirizanitsa a BNC amagwiritsidwa ntchito polumikiza zipangizo zomwe zimagwira pafupipafupi (oscilloscopes, generator, etc.), kulandira ndi kutumiza zipangizo, ma antennati satetezi, makanema a televizioni, makamera a CCTV. Kuwonjezera pamenepo, ojambulirawa amagwiritsidwa ntchito pokonza makanema a m'deralo pogwiritsa ntchito matekinoloje a Ethernet, 10Base2 komanso 100GBase. Kuti muchite izi, gwiritsani ntchito T-connector, "tee". Msewuwa umagwirizanitsidwa ndi malo ofanana, ndipo nthambi imapita ku malo ochezera (networkwork). Mapeto ogwirizanitsa ali ndi kuthetsa mapulagizi kuti asokoneze mawonekedwe omwe amaoneka (ayima).

Kawirikawiri, chingwe ("mayi") chimayikidwa mu zipangizo, ndipo malemba ("daddy") amaikidwa pa chingwe. Pogwiritsa ntchito mapangidwe, ojambulira BNC ndi owongoka ndi owongolera. Zomalizazi zimagwiritsidwa ntchito pamene chingwecho chiyenera kupanga bend, lomwe ndi losafunika kwambiri pa zingwe za coaxial. Choncho, ntchitoyi imapatsidwa ntchito yowonongeka.

Lingaliro la loko la bayonet linali lopambana kwambiri. Kugwiritsidwa kwayiku ndizosokoneza kugwiritsira ntchito, popeza nkofunika kuti mutembenuzire chingwe pambali pa axis. Nthaŵiyi sizimawongolera ngakhale mgwirizano wa nut. Mafakitale ophatikizidwa ali ndi malo opanikizana, kutembenuka molakwika ndikusowa nthawi yochulukira kuti agwirizane ndi kutulutsa chojambulira. Kulumikizana kwotsutsana, monga zipangizo zam'nyumba, sikovomerezeka, chifukwa chojambulira ndi chophweka kwambiri kuchoka mu chingwe.

Bayonet ndi yophweka kwambiri kutseka ndi kutseguka. Zokwanira kusindikizira chojambulira ndi kuzisinthasintha pazitsulo. Zonsezi sizikutenga zoposa yachiwiri. Pa nthawi yomweyo, chojambulira sichitha kuchotsedwa.

Choncho, BNC chojambulira chinalowetsa pafupifupi zolumikiza zonse pakati pa zipangizo za laboratory. Kwa makompyuta, amathandiziranso bwino - chifukwa cha liwiro la kugwira ntchito limodzi ndi kuthekera kwa kusokonezeka mwangozi.

Kulemba kwa BNC kumaphatikizapo njira zotsatirazi:

• BNC - soldering kapena crimping;
• BNC-T - tee (kwa adapita Ethernet);
• BNC-F - threaded connector version;
• BNC-I - kugwirizana kwa zingwe ziwiri.

Zida zowunikira, zowonongeka zokhazokha, ndipo makamaka, zogwiritsidwa ntchito ndi golide ziyenera kugwiritsidwa ntchito. Izi zimachepetsa zolakwika. Kwa nthawi zina, zolumikiza ziphuphu ndizoyenera, koma ziyenera kukwera pokhapokha ndi chida chodziwika bwino. Zoterezi zotsalirazi zimakhala zotchipa kusiyana ndi zipangizo, zimakwera mofulumira, choncho zimakhala zabwino kwambiri kuposa kutsekemera.

Choncho, ngati mukufuna kukonza makanema a "n" makanema amtundu wanu, ndiye kuti mukuyenera kuchita "osachepera" 2n "pa zingwe, ndipo nthawi zina zambiri.
