Njengenxalenye ebalulekileyo yamacandelo e-passive, i-RF coaxial connectors ineempawu ezilungileyo zokuhambisa i-broadband kunye neendlela ezahlukeneyo zokudibanisa ezilula, ngoko zisetyenziswa ngokubanzi kwizixhobo zokuvavanya, iinkqubo zezixhobo, izixhobo zonxibelelwano kunye nezinye iimveliso.Ukusukela oko ukusetyenziswa kweziqhagamshelo zeRF coaxial kungene phantse kuwo onke amacandelo oqoqosho lwesizwe, ukuthembeka kwayo kuye kwatsala umdla ngakumbi nangakumbi.Iindlela zokungaphumeleli ze-RF coaxial connectors zihlalutywa.
Emva kokuba i-N-type i-connector pair idibaniswe, indawo yokudibanisa (inqwelo-moya yombane kunye neyomatshini) yomqhubi wangaphandle wedibanti yokudibanisa igxininiswe omnye komnye ngoxinzelelo lwentambo, ukwenzela ukuba ufezekise ukuchasana okuncinci (< 5m Ω).Inxalenye yepini yomqhubi wepini ifakwe kumngxuma we-conductor kwi-socket, kunye noqhagamshelwano oluhle lombane (ukuchasana koqhagamshelwano <3m Ω) kugcinwa phakathi kwabaqhubi ababini bangaphakathi emlonyeni we-conductor kwi-socket ngokusebenzisa ukuqina kodonga lwesokhethi.Ngeli xesha, umgangatho wesinyathelo somqhubi kwipini kunye nobuso bokugqibela bomqhubi kwi-socket ayigxininiswe ngokuqinileyo, kodwa kukho i-gap <0.1mm, enempembelelo ebalulekileyo ekusebenzeni kombane kunye nokuthembeka kombane. isidibanisi coaxial.Imeko efanelekileyo yokudibanisa i-N-type connector pair ingashwankathelwa ngolu hlobo lulandelayo: uqhagamshelwano olulungileyo lomqhubi wangaphandle, uqhagamshelwano olulungileyo lomqhubi wangaphakathi, inkxaso efanelekileyo yenkxaso ye-dielectric kwi-conductor yangaphakathi, kunye nokuhanjiswa okuchanekileyo koxinzelelo lwentambo.Nje ukuba imeko yoqhagamshelo itshintshile, isinxibelelanisi siya kusilela.Masiqale ngala manqaku kwaye sihlalutye umgaqo wokungaphumeleli wekhonkco ukufumana indlela echanekileyo yokuphucula ukuthembeka kwekhonkco.
1. Ukungaphumeleli okubangelwa ukudibana kakubi komqhubi wangaphandle
Ukuze kuqinisekiswe ukuqhubeka kwezakhiwo zombane kunye noomatshini, imikhosi phakathi kweendawo zoqhagamshelwano zabaqhubi bangaphandle ngokuqhelekileyo zikhulu.Thatha isihlanganisi sohlobo lwe-N njengomzekelo, xa i-torque yokuqinisa i-Mt ye-screw sleeve isemgangathweni we-135N.cm, ifomula Mt=KP0 × 10-3N.m (K yi-coefficient ye-torque yokuqinisa, kunye no-K = 0.12 apha), uxinzelelo lwe-axial P0 lomqhubi wangaphandle lungabalwa ukuba lube yi-712N.Ukuba amandla omqhubi wangaphandle ahluphekile, kunokubangela ukuguga okunzulu kobuso bokudibanisa bomqhubi wangaphandle, kunye nokuguqulwa kunye nokuwa.Umzekelo, ubukhulu bodonga lobuso besiphelo somdibanisi wangaphandle wesiphelo sendoda yesinxibelelanisi se-SMA sincinci, sincinci, kuphela yi-0.25mm, kwaye izinto ezisetyenziswayo ubukhulu becala lubhedu, lunamandla abuthathaka, kwaye itorque yokudibanisa inkulu kancinane. , ngoko ubuso besiphelo sokudibanisa bunokukhubazeka ngenxa yokugqithisa okugqithisileyo, okungonakalisa umqhubi wangaphakathi okanye inkxaso ye-dielectric;Ukongeza, umphezulu womqhubi wangaphandle wekhonkco udla ngokugqunywa, kwaye ukugquma kobuso besiphelo sokudibanisa kuya konakaliswa ngamandla amakhulu oqhagamshelwano, okukhokelela ekunyukeni kokuchasana koqhagamshelwano phakathi kwabaqhubi bangaphandle kunye nokuncipha kombane. ukusebenza kwesihlanganisi.Ukongeza, ukuba i-RF coaxial connector isetyenziswa kwindawo enzima, emva kwexesha elithile, umaleko wothuli uya kufakwa kwisiphelo sokudibanisa somqhubi wangaphandle.Olu luhlu lothuli lubangela ukuchasana koqhagamshelwano phakathi kwabaqhubi bangaphandle ukuba kwandiswe ngokukhawuleza, ukulahleka kokufakwa kwesixhumi kwanda, kwaye isalathisi sokusebenza kombane siyancipha.
Amanyathelo okuphucula: ukuphepha ukudibanisa kakubi komqhubi wangaphandle obangelwa ukuguqulwa okanye ukugqoka ngokugqithiseleyo kobuso bokugqibela bokudibanisa, ngakwesinye icala, sinokukhetha izinto ezinamandla aphezulu ukucubungula umqhubi wangaphandle, njengobhedu okanye insimbi engenasici;Kwelinye icala, ubukhulu bodonga lobuso bokudibanisa isiphelo somqhubi wangaphandle bunokwandiswa ukwandisa indawo yoqhagamshelwano, ukwenzela ukuba uxinzelelo kwindawo yeyunithi yobuso besiphelo sokudibanisa umqhubi wangaphandle uya kuncitshiswa xa okufanayo. itorque yokudibanisa isetyenziswa.Ngokomzekelo, i-SMA coaxial connector ephuculweyo (i-SuperSMA ye-SOUTHWEST Inkampani e-United States), i-diameter yangaphandle yenkxaso yayo ephakathi yi-Φ 4.1mm encitshiswe ukuya ku-Φ 3.9mm, ubukhulu bodonga lomphezulu wokudibanisa we-conductor yangaphandle bunyuka ngokuhambelanayo. ukuya kwi-0.35mm, kwaye amandla omatshini aphuculwe, ngaloo ndlela ephucula ukuthembeka koqhagamshelwano.Xa ugcina kwaye usebenzisa isinxibelelanisi, gcina isiphelo sokudibanisa somqhubi wangaphandle sicocekile.Ukuba kukho uthuli kuyo, yisule ngebhola yekotoni yotywala.Kufuneka kuqatshelwe ukuba utywala akufanele bufakwe kwinkxaso yeendaba ngexesha lokukhuhla, kwaye isidibanisi akufanele sisetyenziswe de utywala buguquguquke, ngaphandle koko i-impedance ye-connector iya kutshintsha ngenxa yokuxuba utywala.
2. Ukungaphumeleli okubangelwa ukudibana kakubi komqhubi wangaphakathi
Xa kuthelekiswa nomqhubi wangaphandle, umqhubi wangaphakathi kunye nobukhulu obuncinci kunye namandla aphantsi kunokwenzeka ukuba abangele ukudibanisa kakubi kwaye kukhokelela ekungaphumeleli kwekhonkco.Uqhagamshelo olulastiki luhlala lusetyenziswa phakathi kwee-conductor zangaphakathi, ezifana ne-socket slotted elastic connection, i-spring claw ne-elastic connection, i-bellows i-elastic connection, njl njl. uluhlu.
Amanyathelo okuphucula: Singasebenzisa amandla okufaka kunye nokugcinwa kwepini ye-gauge ye-standard gauge kunye ne-conductor kwi-socket ukulinganisa ukuba ukuhambelana phakathi kwesokethi kunye nepini kunengqiqo.Kwizihlanganisi zohlobo lwe-N, i-diameter Φ 1.6760+0.005 Amandla okufaka xa i-pin yegeji eqhelekileyo ihambelana nejekhi kufuneka ibe ≤ 9N, ngelixa i-diameter Φ 1.6000-0.005 iphini yegeji eqhelekileyo kunye ne-conductor kwisokethi iya kuba namandla okugcina ≥ 0.56N.Ngoko ke, sinokuthatha amandla okufaka kunye nokugcina amandla njengomgangatho wokuhlola.Ngokulungelelanisa ubungakanani kunye nokunyamezela kwesiseko kunye nepini, kunye nenkqubo yonyango yokuguga ye-conductor kwi-socket, amandla okufaka kunye nokugcinwa kwamandla phakathi kwepini kunye ne-socket kuluhlu olufanelekileyo.
3. Ukungaphumeleli okubangelwa ukungaphumeleli kwenkxaso ye-dielectric ukuxhasa umqhubi wangaphakathi kakuhle
Njengenxalenye ebalulekileyo ye-coaxial connector, inkxaso ye-dielectric idlala indima ebalulekileyo ekuxhaseni umqhubi wangaphakathi kunye nokuqinisekisa ubudlelwane bendawo ehambelanayo phakathi kwabaqhubi bangaphakathi nangaphandle.Amandla omatshini, i-coefficient yokwandisa i-thermal, i-dielectric rhoqo, i-factor loss factor, i-absorption yamanzi kunye nezinye iimpawu zezinto eziphathekayo zinefuthe elibalulekileyo ekusebenzeni kokudibanisa.Amandla aneleyo omatshini yeyona mfuneko isisiseko kwinkxaso ye-dielectric.Ngethuba lokusetyenziswa kwekhonkco, inkxaso ye-dielectric kufuneka ithwale uxinzelelo lwe-axial oluvela kumqhubi wangaphakathi.Ukuba amandla omatshini wenkxaso ye-dielectric impofu kakhulu, iya kubangela i-deformation okanye umonakalo ngexesha lokudibanisa;Ukuba i-coefficient yokwandiswa kwe-thermal yezinto zikhulu kakhulu, xa iqondo lobushushu litshintsha kakhulu, inkxaso ye-dielectric inokwandisa okanye iyancipha kakhulu, ibangele ukuba umqhubi wangaphakathi akhululwe, awe, okanye abe ne-axis eyahlukileyo kwi-conductor yangaphandle, kwaye kubangele ukuba ubungakanani besiqhagamshelanisi sezibuko ukutshintsha.Nangona kunjalo, ukuxutywa kwamanzi, i-dielectric rhoqo kunye nelahleko ichaphazela ukusebenza kombane kwezihlanganisi ezifana nokulahlekelwa kokufaka kunye ne-coefficient yokubonakalisa.
Amanyathelo okuphucula: khetha izixhobo ezifanelekileyo ukucubungula inkxaso ephakathi ngokweempawu zemathiriyeli edibeneyo efana nendawo yokusetyenziswa kunye noluhlu lwamafrikhwensi okusebenza kwesinxibelelanisi.
