Lihokelo tsa radio frequency (RF) coaxial, tse tsejoang hape e le lihokelo tsa RF, ke likarolo tsa bohlokoa phetisong ea lets'oao la RF/microwave. Ba hokahanya lithapo tsa phetiso ea coaxial ho etsa hore ho be le khokahano lipakeng tsa lisebelisoa/mojule, ho fetisa ka nepo mats'oao a RF le microwave. Li sebelisoa haholo puisanong e se nang mohala, khaso, thelevisheneng, radar le mafapheng a mang.
Ha ho bapisoa le likarolo tse ling tsa elektroniki, lihokelo tsa RF li na le nalane e khuts'oane. Sehokelo sa pele sa RF-sehokelo sa UHF-se qapiloe ka 1930. Nakong ea Ntoa ea II ea Lefatše, ka lebaka la litlhoko tse potlakileng tsa ntoa le nts'etsopele ea likhokahano tsa radar, seea-le-moea le microwave, ho ile ha hlaha letoto la boholo bo mahareng-joalo ka N, C, BNC, le TNC.
Kamora 1958, lihlahisoa tse nyane tse kang SMA, SMB, le SMC li ile tsa hlaha. Ka 1964, molao oa sesole sa US MIL-C-39012, "General Specification for Radio Frequency Coaxial Connectors," e ile ea amoheloa. Ho tloha ka nako eo ho ea pele, lihokelo tsa RF li ile tsa qala ho hola ho isa maemong a maemo, ho seriale le ho kopanya lefatše lohle.
Ke likarolo life tse etsang sehokelo sa RF coaxial? Ho na le mefuta efe? U ka khetha sehokelo se nepahetseng sa RF coaxial joang bakeng sa ts'ebeliso ea hau? A re hlahlobeng ka hloko.
1. Sebopeho le Litšobotsi tsa RF Coaxial Connectors
Lihokelo tsa RF coaxial hangata li na le sekontiri se ka hare, sekontiri sa ka ntle, seintši le sehokelo. Li-conductor tsa ka hare le tsa ka ntle ke mokhanni oa bohareng le thebe ea ka ntle ea tšepe, ka ho latellana, e arotsoe ke insulator ho thibela ho kena-kenana le pontšo le ho lutla. Sehokedi ke karolo ya mantlha ya sehokedi, se sebedisetswang ho kenya kapa ho ntsha hlooho ya sehokedi ho phethela phetiso ya matshwao.
Moralo ona oa sebopeho o fa lihokelo tsa RF coaxial tse sebetsang hantle-tse sebetsang khafetsa khafetsa, bokhoni bo matla ba ho thibela{1}}tšitiso, le ho kenya tšebetsong habonolo le ho ts'epahala.
2. Mekhoa ea ho kenya RF Coaxial Connectors
Lihokelo tsa RF coaxial li ka kengoa ka mekhoa e meraro: ho kenya liphanele (hangata ka li-flange tse 2-hole/4-hole), ho kenya PCB, le ho kenya thapo (lihokelo tsa lithapo). Ho kenya liphanele ho ka aroloa hape ka tšepe ka-ka lebota, ka dielectric ka-ea lebota, ka mefuta ea moea ka lebota, mefuta e ka khonang, le mefuta ea khokahanyo e tobileng.

3. Sehlopha sa Mofuta oa Mohokahanyi
Lihokelo tsa RF coaxial li tla ka mefuta e mengata e fapaneng, e nang le letoto le tsebahalang lefatšeng ka bophara le fetang 20 le litlhaloso tse ling tse ngata. Mefuta e tloaelehileng e kenyelletsa likhokahanyo tsa BNC, likhokahanyo tsa SMA, likhokahanyo tsa N, le likhokahanyo tsa TNC. Mefuta e fapaneng ea lihokelo tsa RF coaxial li sebelisoa maemong a fapaneng.
Mohlala, lihokelo tsa RF coaxial tsa Shenzhen Xinqiyuan Technology li fana ka mefuta e fihlang ho 22 ea likhokahanyo, ho kenyeletsoa 1.85mm, 2.4mm, 2.92mm, 3.5mm, SMA, SSMA, SMP, SSMP (SMPM), BMA, BNC, TNC, MCX/MMCX0, 4,3/1MB segokanyim Sehokelo se seng le se seng se lumellana ka thata le litekanyetso, se fihlela litlhoko tse fapaneng tsa lits'ebetso tse fapaneng tsa sesole le tsa khoebo.
