Coaxial connector yog ib qho ntawm cov khoom tseem ceeb hauv rf teeb liab kis kab mob. Nws lub luag haujlwm tseem ceeb yog kev sib txuas. Nrog rau kev txhim kho ntawm xov tooj cua zaus kev sib txuas lus thev naus laus zis, qhov ntsuas ntawm lub xov tooj cua zaus teeb liab kis tau tus mob loj dua, thiab kev siv xov tooj cua zaus teeb liab kis tau tus mob ntau dua. Raws li, ntau thiab ntau qhov chaw siv coaxial connectors. Hauv cov txheej txheem no, ntau yam sib txawv ntawm RF coaxial connectors tau tshwm sim kom tau raws li ntau yam kev xav tau, thiab ntau hom muaj kev siv sib txawv. Lub coaxial connector yog ib feem siv los txuas qhov kawg ntawm ob shafts. Xyuas kom tseeb tias cov kab nruab nrab ntawm ob axes nyob rau tib axis. Feem ntau yog siv los txuas tus tsav ncej mus rau lub zog tsav thiab hloov cov kev sib hloov ntawm cov ncej tsav mus rau lub zog tsav.
Coaxial Cheebtsam yog yuav luag universally siv nyob rau hauv RF daim ntaub ntawv los yog microwave daim ntawv thov, tshwj tsis yog rau tej yam RF signals uas yuav tsum tau npaum conduction los ntawm waveguides los yog ca kis tau tus mob kab. Raws li qhov tshwm sim, koj tuaj yeem pom cov piv txwv ntawm cov khoom siv coaxial siv nyob rau ntau qhov xwm txheej, suav nrog: cov khoom siv, cov cuab yeej siv hauv tsev lossis cov khoom siv, sab hauv tsev, sab nraum zoov, dav hlau, tsheb av, machinery, robotics, spacecraft, satellites, thiab lwm yam Coaxial cables thiab connectors. kuj muaj ntau yam technologies thiab cov yam ntxwv muab rau lawv siv dav. Kev sib dhos ntawm cov tshuab coaxial no sib npaug sib luag thiab xav tau kev pab ntawm cov cuab yeej tshwj xeeb.
Txawm li cas los xij, qee hom coaxial cables thiab connectors tau sib sau ua ke siv cov txheej txheem ntawm cov cuab yeej thiab cov txheej txheem. Standardized coaxial cable yog Ameslikas siv nyob rau hauv cov tub rog. Cov "Xov tooj cua Guide" los yog RG hom coaxial cable pib hauv Ntiaj Teb Tsov Rog II thiab tau teev nyob rau hauv US Mil-HDBK-216 (US Tub Rog Phau Ntawv Qhia -216) hauv 1962. Txij thaum ntawd los, RG hom coaxial cable muaj ua ntau heev. Qhov no tau ua rau cov cuab yeej siv thiab kev coj ua rau RG coaxial cable sib dhos, suav nrog cov cuab yeej siv thiab kev coj ua hauv cov khoom siv lossis thaum lub sijhawm teeb tsa lossis kev saib xyuas.
Txawm hais tias muaj ntau coaxial cables nrog cov txheej txheem ntxiv, ib qho RG hom coaxial cable muaj plaub txheej. Plaub txheej txheej ntawm coaxial cable yog: txheej tiv thaiv sheath (insulator), hlau thaiv, dielectric insulator thiab central conductor. Lub coaxial connector tsim yog qhov zoo ib yam, tab sis lub hau sab nraud yog txawv. Nyob rau hauv qhov tseeb, hlau thaiv txheej los yog lwm tus neeg xyuas pib ntawm coaxial cable yuav tsum sib npaug zos li qhov ua tau txuas mus rau sab nraud shield coaxial connector, thiab dielectric rwb thaiv tsev yuav tsum yog tib txoj hauv kev los txuas rau cov coaxial connectors kom loj tshaj impedance hloov txo qhov poob. ntawm qhov tam sim no mus rau qhov loj tshaj plaws, thiab qhov chaw tus neeg xyuas pib yuav tsum tau txuas nrog cov coaxial connector pins kom sib npaug li sai tau.
Txoj kev ua haujlwm:
Txhawm rau txuas cov connectors no, cov ntaub thaiv npog sab nraud ntawm coaxial cable yuav tsum tau muab tshem tawm ua ntej. Tus lej tshwj xeeb feem ntau yog hais txog tus naj npawb ntawm precision txiav coaxial cable xaus.
Nws yuav tsum tau muab sau tseg tias lub coaxiality ntawm cable yuav tsum tsis txhob raug txo thaum kawg ntawm lub coaxial cable yog huv si txiav, thiab hais tias tsis muaj hlau fragments yuav tsum nyob twj ywm nyob rau hauv lub insulator. Cov ntaub thaiv npog sab nrauv feem ntau yog muab tshem tawm los ntawm kev siv cov cuab yeej tsim tshwj xeeb npaj nrog lub hom phiaj ntawm kev ua kom tiav qhov kev tshem tawm ntawm cov ntaub thaiv npog sab nrauv yam tsis muaj kev puas tsuaj rau sab nrauv. Tom qab tshem tawm, lub shielding txheej ntawm cov ntawv ci, corrugated los yog stranded conductor yog machined kom phim ib feem ruaj ntawm tus neeg xyuas pib sab nraud ntawm coaxial connector. Tom qab qhov no ua tiav, ib feem ntawm dielectric insulator tuaj yeem raug stripped los ntawm qhov chaw tus neeg xyuas pib kom lub chaw neeg xyuas pib tuaj yeem welded, crimped los yog nias rau hauv nruab nrab tus pin fixture ntawm coaxial connector.
Coaxial connectors feem ntau muaj hlau rings los ntxiv dag zog rau cov neeg kho tshuab connector ntawm lub cable sab nrauv thiab xyuas kom meej RF shielding zoo. Thaum lub coaxial cable thiab coaxial connector yog ua ke los ntawm crimping, vuam, los yog lwm yam txhais tau tias, ntxiv tshav kub shrinkable tubing los yog daim kab xev yog feem ntau siv los xyuas kom meej ib tug muaj zog mechanical kev twb kev txuas ntawm lub sab nraud tiv thaiv sheath ntawm lub coaxial cable thiab cov coaxial kev twb kev txuas ntaus ntawv. Thaum tshav kub kub shrinkable tubing los yog daim kab xev yog ntxiv rau connector ntawm lub cable thiab connector kom txo tau kev nyuaj siab ntawm tus neeg xyuas pib thiab dielectric kev twb kev txuas thiab xyuas kom meej tias cov coaxial sib dhos tseem ua tau raws li qhov xav tau nyob rau hauv tej yam kev ntxhov siab, loads, los yog khoov. Txuas ntxiv mus.
Cov saum toj no yog ib co ntawm cov coaxial connector tsim nyog rau txhua leej txhua tus kom paub cov ntsiab lus ntawm kev tsom xam, kuv vam tias nyob rau hauv cov txheej txheem ntawm txhua leej txhua tus tsuas yog tiv tauj, tuaj yeem muab kev pab rau koj, yog tias muaj teeb meem, kuj tuaj yeem tham nrog me me.
