Tiv thaiv lub cable thiab connector los ntawm kev ntxhov siab ntawm lub cev los ntawm kev siv cov ntaub ntawv tiv thaiv, xws li cable wraps thiab strain reliefs.

Hauv cov ntsiab lus, kom tsis txhob coaxial cable connector tsis ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia rau kev teeb tsa, siv cov cuab yeej tsim nyog, thiab xaiv cov khoom sib txuas tsim nyog rau ib puag ncig thiab daim ntawv thov. Kev saib xyuas tsis tu ncua, xws li tshuaj xyuas cov kev sib txuas rau cov cim ntawm corrosion thiab noo noo buildup, kuj tuaj yeem pab tiv thaiv kev ua tsis tiav thiab ua kom ntseeg tau tias kev ua tau zoo.
Yuav ua li cas kom raug siv thiab tswj lub coaxial cable txuas?
Kev siv kom raug thiab kev saib xyuas tsis tu ncua tuaj yeem pab ua kom lub neej ntev ntawm lub coaxial cable txuas. Nov yog qee cov lus qhia txog kev siv kom raug thiab tswj cov coaxial cable txuas:

1. Siv qhov tsim nyog txuas rau koj daim ntawv thov: Lub coaxial cable connector yuav tsum phim cov cable hom, impedance, thiab ntau zaus ua haujlwm kom raug. Kev siv cov khoom sib txuas tsis raug lossis cov khoom sib txuas tsis sib xws tuaj yeem ua rau muaj teeb meem ntau ntxiv thiab txo kev ua haujlwm.

2. Siv cov cuab yeej tsim nyog rau kev teeb tsa: Ib txwm siv cov cuab yeej tsim nyog los nruab koj lub connector kom raug. Cov cuab yeej tsis raug tuaj yeem ua rau lub connector lossis cable puas thiab ua rau lub connector tsis muaj zog.

3. Ua raws li cov lus qhia installation: Ua raws li cov chaw tsim khoom cov lus qhia ua tib zoo thaum txhim kho koj lub connector. Nco ntsoov luas lub cable mus rau qhov ntev uas pom zoo, phim qhov chaw tus neeg xyuas pib thiab cov insulator, thiab ceev cov connector rau qhov pom zoo torque.

4. Tiv thaiv ib puag ncig Factors: Ib puag ncig yam xws li ya raws, kub hloov pauv, thiab huab cua huab cua tuaj yeem ua rau cov khoom sib txuas thiab txo nws txoj sia. Siv cov ntaub ntawv tiv thaiv huab cua xws li sealant thiab tiv thaiv cov khoom sib txuas los ntawm huab cua lossis kev ntxhov siab ntawm lub cev siv cov ntaub thaiv npog lossis cov kab ke tswj hwm.

5. Tshawb xyuas thiab khaws cia tsis tu ncua: Tshawb xyuas lub cable thiab connector nquag rau cov paib ntawm kev puas tsuaj thiab xyuas kom cov connectors nruj txaus kom tsis txhob poob teeb liab. Tshem tawm cov plua plav thiab cov khib nyiab, so cov dej noo, thiab siv cov tshuaj ntxuav tu rau cov khoom qias neeg.

6. Hloov cov khoom txuas puas: Yog tias koj pom muaj kev puas tsuaj lossis corrosion, hloov lub coaxial cable txuas tam sim ntawd. Txheeb xyuas qhov xoob xoob, txiav, lossis suab nrov qhov no tuaj yeem yog qhov kev daws teeb meem los txhim kho kev ua haujlwm ntawm koj lub coaxial cable.

Los ntawm kev ua raws li cov lus pom zoo no, koj tuaj yeem pab ua kom lub neej ntev tshaj plaws thiab kev ua tau zoo ntawm koj cov coaxial cable txuas, ua kom ntseeg tau cov teeb liab kis tau tus mob, thiab txo qis cov teeb liab poob thiab cuam tshuam.
Yuav ua li cas xaiv qhov zoo tshaj plaws coaxial cable txuas rau FM tshaj tawm?
Kev xaiv txoj cai coaxial cable txuas rau FM tshaj tawm yog nyob ntawm ntau yam cuam tshuam nrog rau cov ntawv thov tshwj xeeb, cov khoom siv hluav taws xob tso tawm hluav taws xob, qib zaus, hom coaxial cable, thiab kev faib cov kav hlau txais xov. Nov yog qee qhov kev txiav txim siab tseem ceeb uas tuaj yeem pab koj xaiv qhov tsim nyog connector:

1. Daim ntawv thov: Xav txog daim ntawv thov tshwj xeeb rau coaxial cable connector koj xav tau. Piv txwv li, hauv FM tshaj tawm xov xwm, koj yuav xav tau cov khoom sib txuas nrog lub zog tuav lub peev xwm thiab kev sib txuas txhim khu kev qha. Tsis tas li ntawd, xav txog kev khiav hauj lwm zaus thiab cov teeb liab zoo uas yuav tsum tau muaj rau daim ntawv thov, vim qhov no yuav cuam tshuam rau qhov zoo ntawm cov khoom sib txuas.

2. Transmitter tso zis zog theem: Koj yuav tsum xav txog qib fais fab ntawm koj lub transmitter tso zis raws li koj yuav xav tau ib lub connector uas tuaj yeem tswj cov qib fais fab tsis muaj kev cuam tshuam cov teeb liab zoo. Feem ntau, cov khoom siv hluav taws xob siab xws li 7/16 DIN connectors lossis Hom N connectors yog tsim rau high-power FM broadcasting applications.

3. Ntau zaus: Xyuas kom lub connector koj xaiv yog tsim los ua hauj lwm nyob rau hauv tag nrho cov ntau zaus uas yuav tsum tau rau koj FM tshaj tawm daim ntawv thov. BNC thiab TNC connectors yog tsim rau cov ntawv thov tsawg zaus mus txog 4 GHz. Thaum 7/16 DIN connectors thiab Type N connectors yog tsim nyog rau ntau zaus daim ntawv thov mus txog 11 GHz.

4. Coaxial cable hom: Ntau hom coaxial cables muaj ntau theem impedance, core diameters thiab muaj peev xwm tuav fais fab. Cov coaxial sib txawv yog tsim los txuas ntau hom coaxial cables. Xyuas kom lub connector koj xaiv yog sib xws nrog hom coaxial cable koj muaj.

5. Kev faib cov kav hlau txais xov: Ntau hom kav hlau txais xov xav tau ntau hom coaxial cable txuas. Piv txwv li, tus kav hlau txais xov dipole feem ntau xav tau BNC lossis TNC txuas, thaum lub kav hlau txais xov polarized ncig yuav xav tau hom N txuas lossis 7/16 DIN txuas.

Hauv cov ntsiab lus, thaum xaiv qhov zoo tshaj plaws coaxial cable txuas rau FM tshaj tawm, nws yog ib qho tseem ceeb uas yuav tsum xav txog daim ntawv thov, lub zog xa hluav taws xob, ntau zaus, hom coaxial cable, thiab kev faib cov kav hlau txais xov. Kuj xav txog kev ntseeg siab thiab zoo ntawm cov khoom sib txuas, nrog rau cov yam ntxwv xws li tus nqi thiab muaj nyob rau thaum xaiv cov khoom sib txuas uas zoo tshaj plaws rau koj qhov kev xav tau.
