Kakaretšo
The SMB 75 Ohm PCB Male Connector e entsoeng ke Zhenjiang Tongda Company ke compact RF coaxial sehokedi Featuring kgorometsa - ka potlako - kgokahanyo mochine le tšobotsi impedance ya 75Ω. E reretšwe go hloma PCB, e fana ka kgato ye nnyane ya maoto, bonolo bja go hloma, le tshepedišo ya phetišetšo ye e tsepamego.
Sebopego sa motšhene
1. Kgorometša-ka Mokgwa wa go Notlela
Ho fapana le sebopeho threaded sa dikgokelo SMA, SMB dikgokelo tšobotsi e ka hare elastic collet ka hare ho matlo. Ge e tsenywa ka gare ga jack ya tshadi ya SMB, collet e a atološwa gomme ka morago ya tšhologela morago go swara lebota la ka ntle, e kgontšha go nyalana ka pela, go i{1}}go notlela ntle le go nyakega ga go dira ditlhale. E boloka maatla a go kgomaretša gomme e netefatša kgokagano ye e ka botwago le ka morago ga medikologo ya go feta 500 ya go nyalana.
2. Peakanyo ya Sehokedi sa Monna
Sehokedi sa mohuta wa J- (e tona) se na le pini ya bogareng ye e tiilego ye e tšwelelago yeo e hlamilwego go tsenya ka gare ga soketeng ya elastic ya jack ya basadi, go hloma kgokagano ya mohlagase ye e ka botwago. Bokagodimo bja kgokagano ke gauta-plated go fokotša go ganetša kgokagano le go fa kganetšo ya oxidation.
3. PCB Ka -Sebopeho sa ho hlomamisa lesoba (E-mofuta o otlolohileng Thaba) .
Center Pin: Soldered ho PCB pontšo pad ho fetisetsa RF matšoao;
Maoto a fase a pheriferale: A soldered ka dipad tša fase tša PCB, a fa kgokagano ya fase ye e feletšego, ye kopana -tsela ya fase bakeng sa ntlo ya sekopanyi;
Mošomo: E khutsufatša loop ya fase, e fokotša impedance ya tsela ya go boela morago ya RF, e godiša tshepedišo ya go šireletša, gomme e fa botsitso bja motšhene kgahlanong le thothomelo.

Didirišwa le Bokgabo bja Diatla
1. Mmele: Koporo motheo thepa le khauta plating; moruswi-go kgotlelela, go ganetša kgokagano ya fase, ebile go bonolo go solder.
2. Center Pin: Beryllium koporo kapa koporo le khauta plating; elasticity e tsitsitseng.
3. Insulator: PTFE (phahameng - mocheso, phahameng - maqhubu a dielectric).
Mehola ya Setšweletšwa
1. Bogolo bjo bo kopanego- bjo bonnyane go feta SMA- bjo bo loketšego dipeakanyo tša PCB tša go ba le segokanyipalo se se phagamego.
2. Kgorometša - ka intša - notlela mokgwa wa lumella bakeng sa ka potlako haholo ho nyalana le unmating ho feta threaded SMA / BNC dikgokelo.
3. Nepahetseng 75Ω impedance matching netefatsa tlaase pontšo attenuation bakeng sa video le CCTV dikopo.
4. Secure ka - lesoba soldering fana ka tsitsitseng boto - lehlakoreng dikgokelo le thothometsa ho hanyetsa.
5. Theko e tlaase le haholo loketseng bakeng sa tlhahiso e ngata.
Maemo a bohlokwa a tirišo
1. Analog leihlo le coaxial HD video phetiso (RG59 / RG6 thapo - ho - boto kgokelo)
2. Ka-dikgokagano tša boto bakeng sa TV ya kabel le matshwao a kgašo
3. Video transceiver dimmojule le modulation / demodulation potoloho mapolanka
4. Boto ya ka gare-go - dikgokagano tša terata bakeng sa didirišwa le didirišwa tša go dira diteko tša RF
5. RF likoung bakeng sa lik'hamera tshireletso le video encoders
