Coax Connectors
Lub coaxial cable txuas yog ib qho hluav taws xob txuas uas siv los txuas cov khoom siv sab nraud, xws li lub kav hlau txais xov, rau lub coaxial cable. Cov khoom sib txuas no yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees thiab kev ncaj ncees ntawm cov xov tooj cua zaus (RF) cov teeb liab raug xa los ntawm FM xov tooj cua transmitter.
Muaj ob peb lub ntsiab lus rau coaxial cable connector, nrog rau RF connector, xov tooj cua zaus connector, thiab coax connector. Cov ntsiab lus no feem ntau siv sib hloov pauv mus rau txhua hom kev sib txuas uas siv los txuas coaxial cables lossis cov kab sib txuas hauv xov tooj cua zaus siv.
Lub coaxial cable connector muaj ob lub hauv paus ntsiab lus: ib tug txiv neej connector uas txuas nrog lub coaxial cable, thiab ib tug receptacle uas yog txuas mus rau lub ntaus ntawv uas lub cable yuav txuas. Cov connectors no yog tsim los tswj lub impedance tsis tu ncua rau RF teeb liab los ntawm lub connector, vim impedance mismatches yuav ua rau lub teeb liab xav thiab poob.
Lub connector ua haujlwm los ntawm kev siv qhov chaw tus neeg xyuas pib ntawm lub coaxial cable, uas nqa lub teeb liab RF, ua rau kev sib cuag nrog lub qhov (socket) sib thooj hauv lub tshuab txais khoom. Nyob rau tib lub sijhawm, tus neeg xyuas pib sab nraud ntawm coaxial cable, hu ua daim thaiv npog, yog compressed nyob ib ncig ntawm lub receptacle sab nraud connector lub cev kom tswj tau qhov kev sib txuas thiab ua kom tiav cov shielding nyob ib ncig ntawm lub teeb liab RF.
Muaj ntau ntau hom coaxial cable connectors muaj nyob rau hauv kev ua lag luam, nrog rau cov qauv sib txawv thiab cov yam ntxwv. Cov hom nrov tshaj plaws ntawm coaxial cable connectors muaj xws li BNC, N-hom, SMA, thiab F-hom connectors. Hom connector siv nyob ntawm seb qhov kev thov tshwj xeeb, xws li qhov ntau zaus ntawm lub teeb liab, lub zog tso zis, thiab qhov xav tau kev ua haujlwm.
Lub coaxial cable txuas yog qhov tseem ceeb hauv kev tshaj tawm vim nws muab kev ruaj ntseg thiab txhim khu kev qha kev sib txuas ntawm coaxial cable los yog kab sib txuas thiab kav hlau txais xov lossis transmitter.
