BNC Connector

• Brief gabatarwa

Mai haɗin BNC (Turanci: Bayonet Neill Concelman, a zahiri an fassara shi da "Neill Concelman bayonet") tashar tashar RF ta gama gari ce ta gama gari. Mai haɗin kebul na BNC ya ƙunshi fil ɗin tsakiya, jaket, da soket. Ya ƙunshi sassa uku: tushen haɗin BNC, murfin waje, da bincike. Ana kiran mai haɗin BNC bayan tsarin kullewa da masu ƙirƙira, Paul Neill na Bell Labs (wanda ya ƙirƙira tashar N) da Karl Conceman na Amphenol (wanda ya ƙirƙira tashar C). Dole ne a haɗa masu haɗin kebul na BNC zuwa ƙarshen kowane ɓangaren na USB.

Masu haɗin BNC sun haɗa da:

1. shugaban BNC-T, ana amfani dashi don haɗa katunan sadarwar kwamfuta da igiyoyi a cikin hanyar sadarwa;

2. BNC mai haɗin ganga, ana amfani da shi don haɗa igiyoyi na bakin ciki guda biyu cikin igiya mai tsayi;

3. Mai haɗin kebul na BNC, wanda aka yi amfani da shi don waldawa ko murɗawa a ƙarshen kebul;

4. BNC m, amfani da su hana tsangwama lalacewa ta hanyar siginar tunani baya bayan kai na USB karya. Terminator wani nau'in haɗi ne na musamman wanda ke ƙunshe da tsayayyen zaɓin resistor wanda yayi daidai da halayen kebul na cibiyar sadarwa. Kowane tasha dole ne a yi ƙasa.

• Kimar inganci

1.Daga saman samfurin, yana da kyau a sami sutura mai haske da m. Mafi girman tsarkin jan karfe, mafi haske shine. Wasu samfuran suna da waje mai haske amma an yi su da ƙarfe.

2. Don gwajin adsorption na magnetite, gabaɗaya kawai bazarar bayoneti da bazarar wutsiya an yi su ne da kayan ƙarfe; Makullin waya, fil, da casing an yi su ne da tagulla, yayin da sauran abubuwan da aka yi su da zinc gami.

3. Cire rufin saman don ganin kayan: Yi amfani da kayan aiki masu kaifi kamar ruwan wukake don goge murfin saman don ganin kayan a gani, da kwatanta kayan samfur ta hanyar goge murfin igiyar waya, fil, da hannayen kariya.

Baya ga hanyoyin da ke sama, zaku iya shirya shugaban mace mai inganci don gwaji.

• Origin

Masu haɗin BNC sun yi kama da na B da C. Mai haɗin zaren TNC (Threaded Neill Concelman) yana da mafi kyawun aiki a cikin rukunin microwave idan aka kwatanta da BNC.

• bayani dalla-dalla

Masu haɗin BNC sun zo cikin nau'i biyu: 50 ohm da 75 ohm.

Lokacin haɗa mai haɗin 50 ohm zuwa wasu igiyoyin impedance, yuwuwar kurakuran watsawa ya yi ƙasa kaɗan. Siga daban-daban na masu haɗawa sun dace da juna, amma idan impedance na USB ya bambanta, siginar na iya nunawa. Yawancin lokaci, ana iya amfani da masu haɗin BNC a 4GHz ko 2GHz.

Ana amfani da haɗin 75 ohm don haɗa bidiyo da DS3 zuwa babban ofishin kamfanin tarho, yayin da mai haɗin 50 ohm ke amfani da bayanai da watsa RF. Haɗin da ba daidai ba na filogi 50 ohm zuwa soket 75 ohm na iya lalata soket. Yi amfani da masu haɗin ohm 75 a cikin aikace-aikacen mitoci masu yawa.

• Umurnai

Ana amfani da masu haɗin BNC don watsa siginar RF, gami da watsa siginar analog ko dijital bidiyo, haɗin eriyar kayan aikin rediyo mai son, haɗin kayan lantarki na jirgin sama, da sauran kayan gwajin lantarki. A fagen kayan lantarki na mabukaci, masu haɗin BNC da aka yi amfani da su don watsa siginar bidiyo an maye gurbinsu da tashoshi na RCA. Tare da adaftan mai sauƙi, ana iya amfani da tashoshi na RCA akan na'urori waɗanda kawai ke da masu haɗin BNC.

An yi amfani da tashoshi na BNC a ko'ina cikin 10base2 Ethernet, amma saboda maye gurbin igiyoyin coaxial tare da igiyoyi masu karkace, yana da wuya a ga katunan cibiyar sadarwa tare da tashoshi na BNC. Wasu cibiyoyin sadarwa na ARCNET suna ƙare igiyoyin coaxial tare da tashoshi BNC.

• Makamantan masu haɗawa

Ana amfani da masu haɗin BNC da yawa a cikin NIM, amma an maye gurbinsu da ƙaramin LEMO 00. Ƙarƙashin yanayin ƙarfin lantarki, masu haɗin MHV da SHV sun fi yawa. Ana iya haɗa masu haɗin MHV da ƙarfi zuwa masu haɗin BNC. SHV shine mai haɗin kai mafi aminci wanda aka haɓaka a sakamakon haka, kuma ba za a iya haɗa shi da masu haɗin BNC na yau da kullun ba.

A cikin tsohuwar yankin Tarayyar Soviet, an haɗa masu haɗin BNC kamar SR-50 (Rasha: Tsar-50) da SR-75 (Tsar-75). Saboda juyawa daga daular zuwa awo, waɗannan masu haɗin sun bambanta da BNC amma ana iya haɗa su da karfi. Haɗin haɗin BNC mai dual (wanda kuma aka sani da dual axis BNC) yana amfani da mahalli na kulle wuka iri ɗaya kamar BNC, amma ya haɗa da wuraren tuntuɓar masu zaman kansu guda biyu (biyu na toshe soket), yana ba da damar haɗin 78 ohm ko 95 ohm daban-daban nau'i-nau'i, irin wannan. Saukewa: RG-108A.

Suna iya aiki a 100GHz da 100V. Mai haɗin BNC dual bai dace da masu haɗin BNC na yau da kullun ba. BNC axis guda uku (kuma aka sani da TRB) a lokaci guda suna haɗa sigina, yadudduka na garkuwa, da ƙasa. An yi amfani da shi a cikin tsarin ma'aunin lantarki masu mahimmanci, ba za a iya amfani da shi kai tsaye tare da masu haɗin BNC ba, amma ana iya haɗa shi da masu haɗin BNC na gaba ɗaya ta hanyar adaftan.
