Isishwankathelo
I-SMB 75 Ohm PCB yaMale Connector eyenziwe yiZhenjiang Tongda Inkampani sisidibanisi esihlangeneyo seRF esidibanisayo esinotyhala-okukhawulezayo{2}}ukudibanisa isixhobo kunye nesiciko esithintelayo se-75Ω. Idizayinelwe ukunyuswa kwePCB, ibonelela ngeenyawo ezincinci, ngokulula ukufakela, kunye nokusebenza okuzinzileyo kothumelo.
Ubume bomatshini
1. Tyhila{1}}kwiNdlela yokuTshixa
Ngokungafaniyo nolwakhiwo oludityanisiweyo lweziqhagamshelo ze-SMA, iziqhagamshelo ze-SMB zibonakalisa i-elastic collet yangaphakathi ngaphakathi kwindlu. Emva kokufaka kwijekhi ye-SMB yowesifazane, ikholethi iyakhula kwaye iphinde ibuyele umva ukuze ibambe udonga olungaphandle, ivumela ukukhwelana ngokukhawuleza,{1}}ukutshixa ngaphandle kwesidingo sokuthunga. Igcina amandla okubamba kwaye iqinisekisa uqhagamshelwano oluthembekileyo nasemva kwemijikelo yokukhwelana engaphezu kwama-500.
2. Uqwalaselo lweSidibanisi seNdoda
-Isidibanisi sohlobo (indoda) sinephini eliqhagamshele eliqinileyo elisembindini eyenzelwe ukufaka kwisokethi yelastiki yejoyi, ukuseka uqhagamshelwano oluthembekileyo lombane. Umphezulu woqhagamshelwano yigolide{2}}yalekwe ukunciphisa ukuxhathisa ukudibana kunye nokubonelela ukuxhathisa kwi-oxidation.
3. I-PCB Nge{1}}ngeSakhiwo sokuFaka umngxuma (E{2}}uhlobo lweMount eSight)
I-pin esembindini: Ithengiswe kwiphedi yomqondiso we-PCB ukuhambisa imiqondiso yeRF;
Imilenze ye-peripheral grounding: Ithengiswe ngeepads zokumisa ze-PCB, ibonelela ngodibaniso olubanzi,-olufutshane lwendlela yomhlaba yesidibaniso sendlu;
Umsebenzi: Yenza mfutshane iluphu esezantsi, icuthe indlela yokubuya yeRF, iphucula ukusebenza kwekhuselo, kwaye ibonelela uzinzo lomatshini ngokuchasene nokungcangcazela.

Izinto eziphathekayo kunye nobugcisa
1. Umzimba: Isiseko sobhedu esinezitya zegolide; umhlwa -iyaxhathisa, ukuchasana okuphantsi, kwaye kulula ukuyithengisa.
2. Isikhonkwane esiphakathi: Iberyllium yobhedu okanye ubhedu olufakwe igolide; ukuqina okuzinzileyo.
3. Isigqubuthelo: PTFE ({1}}ubushushu obuphezulu, -i-frequency dielectric).
Iinzuzo zeMveliso
1. Ubungakanani obubambeneyo - buncinci kune SMA -bufanelekele{3}}ubuninzi be PCB uyilo.
2. Ukutyhala{1}}kukuzitshixa{2}}indlela yokutshixa ivumela ukukhwelana okukhawulezileyo kunye nokungahlangani kuneziqhagamshelo ze-SMA/BNC ezinemisonto.
3. I-75Ω echanekileyo yokulinganisa i-impedance iqinisekisa ukuthotywa komqondiso ophantsi wevidiyo kunye nezicelo zeCCTV.
4. Secure through-hole soldering provides stable board-side connections and vibration resistance.
5. Iindleko eziphantsi kwaye zifanelekile kakhulu kwimveliso yobuninzi.
Iimeko zesicelo eziphambili
1. Uphononongo lwe-analog kunye ne-coaxial HD ividiyo yosasazo (RG59/RG6 intambo -ukuya{4}}uqhagamshelwano lwebhodi)
2. Kwibhodi{1}}ujongano lwentambo kamabonakude kunye nemiqondiso yosasazo
3. Iimodyuli zevidiyo ze-transceiver kunye ne-modulation/demodulation circuit boards
4. Ibhodi yangaphakathi -uku{2}}ukudityaniswa kwecingo kwisixhobo kunye nezixhobo zovavanyo lweRF
5. Izibuko zeRF zeekhamera zokhuseleko kunye neekhowudi zevidiyo
