Kwayoyin BNC (Bayonet Neill Concelman, kewaye ne daidai a ceelin 'Neill Concelman bayonet') yayi shugaban gaba daidai a cikin kawayen RF. Kwayoyin kabel BNC yayi mai tsawo da idon gida, wani sabon kwayoyin, da kwayoyin. An yi shirin hanyar: base kwayoyin BNC, sabon gabatar, da idon. Kwayoyin BNC suna zauna suka samu masu namunƙwarwa su da masuɓakonci su, Paul Neill a Bell Labs (an yi kwayoyin N) da Karl Conceman a Amphenol (an yi kwayoyin C). Kwayoyin kabel BNC bata yana zama daga abubuwan kabin.

• Nau'i

Kwayoyin BNC suna:

1. T-BNC, an yi amfani da wannan a cikaɗan kasar computer network cards da kabele a cikin wannan network;

2. Sabon kwayoyin BNC, an yi amfani da wannan a cikaɗan abubuwan kabele biyu a zage jajjige kabele talakaƙi;

3. Kwayoyin kabele BNC, an yi amfani da wannan a cikaɗan tattabburar da kiyaye a turmisar kabele;

4. Kwaya BNC, an tsaye daidai a cikin kewayan tunyauna na rayuwar signal don hanyar gaba ga cikin wannan kwaya. Kwaya suna ne kwayan labari mai wucewa daya amfani da resistor mai shirye da aka samun bayanai da cikin kawayen kibun. Daga gaban kwaya mutane yanzu ba suka yi shawo.

• Taimakon alamanci

1.Daga faruwar rubutu, ya kamata da coating mai sauran da mai sauri. Jika purity na copper ba, ya kamata da coating mai sauran da mai sauri. Suna rubutu mai sauran da mai sauri akanƙasa, amma ya fiye iron.

2. A cikin tabbatar maganin magnetite, abokan yanzu kasuwanci bayan spring na bayanin da tail spring ya fiye iron; Wire clamp, pins, da casing ya fiye copper, amma komponent mai sabon nufin ya fiye zinc alloy.

3. Shafin coating na faruwar daga gabatar da aka samun mataki mai shirye mai sharadda a cikin coating na faruwar da aka samun wire clamp, pins, da shielding sleeves.

Kawai da aikin kula, kuna iya shigar da makon gaba mai cikinna na femi a ce testi.

• Gidamai

Gudanar BNC suna ne yanzu da gudanan B da C. Gudanar TNC (Threaded Neill Concelman) ya kasance masani daidai a cikin bandin microwave kuma da gudanar BNC.

• Bayanan

Gudanar BNC suka ne biyu wata: 50 ohm da 75 ohm.

A wannan sunan, lokacin transmission errors ya zaka ne kawai da sabon gudanar kabiye a samun impendans, lokacin transmission errors ya zaka ne kawai da sabon gudanar kabiye a samun impendans. Wannan versionin gudana suka ne mutum-mutum, amma idan ta impendansin kabe suka different, signal ya zaka ne reflected. Kafin haka, gudanar BNC suka ne mutum-mutum a samun 4GHz ko 2GHz.

Gudanar 75 ohm ya iya shiga video da DS3 a cikin office na telephone, kuma gudanar 50 ohm ya iya shiga data da RF transmission. Shiganar gabatar gudanar 50 ohm a cikin socket na 75 ohm ya kamata socket. Iya yiwa gudanar 75 ohm a samun applications na very high frequency.

• Rubutun

Kewayyoyin BNC yana gudanar daidai amfani da RF signals, wata daidai a ce transmission na analog ko digital video signals, connection na equipment na radio amature antennas, connection na electronic equipment na aviation, daidai kuma na testing equipment. A cikin field na consumer electronics, kewayyoyin BNC na transmission na video signal ya yi shawarwar da RCA terminals. A kan adapter na farko, terminals na RCA yana iya tambayyawa a matsayin dai dai an yi shawarwar da BNC connectors.

Terminals na BNC yana gabatar daidai a 10base2 Ethernet, kuma ana soƙon guda coaxial cables ya yi replaced with twisted pair cables, ya fi nuna da network cards an yi shawarwar da BNC terminals. Sabon sababbin ARCNET networks yana terminate coaxial cables da BNC terminals.

• Kewayyo similar

Kewayyoyin BNC yana gudanar da ake samun a NIM, kuma ya tafiya da LEMO 00 na cikakken. A cikin shirin rubutu, kewayyoyin MHV da SHV yana gudanar da. Kewayyoyin MHV yana sona daidai connected to kewayyoyin BNC. SHV ne kewayyo suna mai hanyar safi dai dai ta fiye, an yi shi a kan samun regular BNC.

A cikin aiki ne Soviet Union, kewayyoyin BNC yana kasance da SR-50 (Russian: Tsar-50) da SR-75 (Tsar-75). Takadduna na takardunwa da metric, kewayyoyin wannan ne bincike da BNC kuma yana sona daidai connected. Kewayyo dual plug BNC (da aka samun dual axis BNC) yana samun miso na knife lock housing na BNC, kuma yana samun biyu matakan contact points (ƙasa na plug sockets), ake sona daidai da connection of 78 ohm ko 95 ohm differential pairs, mai tsarin RG-108A.

Sunan ake yi amfani da 100GHz da 100V. Kungiya dual BNC bata ta fi kwance da kungiyar BNC mutum. Kungiya BNC talaka (da yanzu an suna TRB) ya kawo shafin tsarin, rubutun gaskiya, da cikinƙasa daga cikin wuce. Yanar gizo daidai na masuwa elektroniki, ana bata ake samfuna da kungiyar BNC mutum, kana samun samunna da kungiyar BNC mutum daya ta hanyar adaptars.
