Lub npe hu ua Bayonet Neill-Concelman connectors, yog ib hom coaxial connector uas tau siv dav hauv kev lag luam hluav taws xob rau ntau xyoo lawm. Cov connectors no muaj npe nrov rau lawv qhov yooj yim ntawm kev siv, txhim khu kev qha kev ua tau zoo, thiab kev sib txuas ruaj ntseg. Lawv tau pib tsim nyob rau thaum ntxov 1940s los ntawm Paul Neill thiab Carl Concelman rau lub tuam txhab xov tooj cua Asmeskas, feem ntau yog rau kev sib txuas hauv xov tooj cua hauv TV thiab xov tooj cua los muab cov teeb liab ruaj khov thiab kev sib txuas yooj yim thiab kev sib txuas.
BNC connector muaj lub hauv paus tus pin rau lub teeb liab thiab lub plhaub sab nraud rau hauv av, kom ntseeg tau tias muaj kev cuam tshuam tsawg heev thiab muaj kev ntseeg siab. Nws yog tus yam ntxwv los ntawm ob-stud bayonet-style locking mechanism, uas muab kev ruaj ntseg tsis tau yooj yim detachable kev twb kev txuas. Sij hawm dhau mus, BNC cov khoom txuas tau raug txhim kho thiab ua kom zoo dua qub, nrog rau kev qhia ntawm 75-ohm BNC connectors los ua haujlwm rau cov khoos phis tawj, thiab ntau yam qauv tsim kom haum rau ntau hom kev siv, suav nrog ncaj, flange, thiab SMT.
BNC connectors muaj nrog ob tus qauv impedances, 50 ohms thiab 75 ohms. Lub 50-ohm version feem ntau yog siv rau hauv xov tooj cua thiab video daim ntawv thov, thaum lub 75-ohm version yog siv rau computer networking daim ntawv thov. Nws yog ib qho tseem ceeb heev uas lub connector impedance phim lub cable thiab cov khoom siv rau kev pom cov teeb liab kis tau tus mob. Qhov ntau zaus ntawm BNC connectors feem ntau yog nyob nruab nrab ntawm DC thiab 4 GHz, nyob ntawm cov coaxial cable siv thiab impedance ntawm lub connector.
BNC connectors vS TNC connectors
BNC connector
Haum rau ntau zaus ntawm 0-4GHz, nws yog coaxial cable connector nrog ib tug bayonet kev twb kev txuas mechanism siv rau tsawg-power applications.
TNC connector
Lub TNC connector yog ib tug variation ntawm BNC connector thiab siv ib tug threaded kev twb kev txuas mechanism los txuas coaxial cables nyob rau hauv cov khoom siv wireless thiab cov cuab yeej kuaj. Nws qhov siv tau ntau zaus yog 0-11GHz.
Keeb kwm, BNC connectors tau siv hauv xov tooj cua thiab TV tshaj tawm los txuas cov kav hlau txais xov thiab cov khoom siv xov tooj cua. Lawv kuj tau pom cov ntawv thov hauv Ethernet network los txuas cov khoom siv xws li khoos phis tawj, hubs, thiab keyboards. Tsis tas li ntawd, BNC connectors yog siv rau hauv kev ntsuas thiab ntsuas los txuas ntau yam kev ntsuas thiab ntsuas cov cuab yeej, suav nrog oscilloscopes, teeb liab generators, thiab spectrum analyzers. Lawv kuj tseem siv rau hauv kev soj ntsuam video los txuas cov koob yees duab soj ntsuam thiab cov kaw suab video, nrog rau hauv thaj chaw aerospace rau kev sib txuas radar, cov khoom siv sib txuas lus satellite, thiab cov sensors rau cov tsheb ya. Hauv kev kho mob, BNC connectors tuaj yeem txuas ntau yam khoom siv kho mob, xws li electrocardiograms thiab ultrasounds.
Txawm hais tias kev nce qib ntawm kev siv thev naus laus zis thiab kev qhia txog cov ntaub ntawv tshiab ntawm kev sib txuas, BNC connectors tseem cuam tshuam rau qee yam kev siv uas yuav tsum muaj kev sib txuas coaxial. Lawv qhov kev ruaj ntseg thiab kev ntseeg siab hauv cov teeb liab kis tau tus mob, nrog rau lawv qhov yooj yim ntawm kev sib txuas thiab kev sib txuas, txuas ntxiv ua rau lawv nyiam xaiv hauv ntau qhov chaw.
Hom kev sib txuas no tuaj yeem txuas tau sai thiab sib cais, nrog cov yam ntxwv xws li kev sib txuas txhim khu kev qha, kev co zoo, thiab kev sib txuas yooj yim thiab sib cais. Nws yog qhov tsim nyog rau kev sib txuas ntau zaus thiab sib cais thiab siv dav hauv cov khoom siv wireless thiab cov cuab yeej ntsuas los txuas coaxial RF cables.
