Nkigice cyingenzi cyibigize pasiporo, umuhuza wa RF coaxial ufite uburyo bwiza bwo kohereza umurongo mugari hamwe nuburyo butandukanye bworoshye bwo guhuza, bityo bikoreshwa cyane mubikoresho byipimisha, sisitemu yintwaro, ibikoresho byitumanaho nibindi bicuruzwa.Kuva ikoreshwa rya RF coaxial ihuza ibice hafi yubukungu bwigihugu, ubwizerwe bwaryo nabwo bwashimishije abantu benshi.Uburyo bwo kunanirwa bwa RF coaxial ihuza irasesengurwa.
Nyuma yo guhuza N-ubwoko bwa N-ihuza, ubuso bwo guhuza (indege ya mashini na mashini yerekana indege) yumuyobozi winyuma wihuza byombi bifatanyirizwa hamwe nuburemere bwurudodo, kugirango ugere kubantu bake barwanya (< 5m Ω).Igice cya pin cyumuyoboro muri pin cyinjijwe mu mwobo wuyobora mu mufuka, kandi guhuza amashanyarazi neza (guhuza imikoranire <3m Ω) bigumaho hagati yimiyoboro ibiri yimbere kumunwa wumuyoboro wa sock unyuze kuri ubworoherane bwurukuta rwa sock.Muri iki gihe, intambwe yintambwe yuyobora muri pin hamwe nisura yanyuma yumuyobora muri sock ntabwo ikanda cyane, ariko hariho icyuho cya <0.1mm, gifite ingaruka zikomeye kumikorere yamashanyarazi no kwizerwa kwa umuhuza wa coaxial.Uburyo bwiza bwo guhuza imiterere ya N-ihuza abahuza barashobora kuvunagurwa muburyo bukurikira: guhuza neza nuyobora hanze, guhuza neza nuyobora imbere, inkunga nziza yingoboka ya dielectric kumuyoboro wimbere, hamwe no guhererekanya neza kumurongo.Iyo imiterere yavuzwe haruguru ihindutse, umuhuza azananirwa.Reka duhere kuri izi ngingo tunasesengure ihame ryo kunanirwa kwihuza kugirango tubone inzira nziza yo kunoza ubwizerwe bwumuhuza.
1. Kunanirwa guterwa no guhura nabi nuyobora hanze
Kugirango tumenye neza ko amashanyarazi nubukanishi bikomeza, imbaraga ziri hagati yimikoranire yabatwara hanze muri rusange nini.Fata N-umuhuza wurugero nkurugero, mugihe gukomera kwumuriro Mt wintoki ya screw ari bisanzwe 135N.cm, formula Mt = KP0 × 10-3N.m.Niba imbaraga z'umuyoboro winyuma ari muke, birashobora gutera kwambara cyane mumaso yanyuma ihuza umuyoboro winyuma, ndetse no guhinduka no gusenyuka.Kurugero, uburebure bwurukuta rwumuhuza wanyuma wumuyoboro winyuma wumugabo wanyuma wumugabo wa SMA uhuza ni muto cyane, 0,25mm gusa, kandi ibikoresho byakoreshejwe ahanini ni umuringa, ufite imbaraga nke, kandi itara rihuza ni rinini gato , bityo isura yanyuma ihuza irashobora guhindurwa bitewe no gukabya gukabije, bishobora kwangiza umuyoboro wimbere cyangwa inkunga ya dielectric;Byongeye kandi, ubuso bwumuyoboro winyuma wumuhuza mubusanzwe uba utwikiriwe, kandi igipfundikizo cyuruhande rwumuhuza wanyuma kizangirika nimbaraga nini zo guhuza, bikavamo kwiyongera kwimyitwarire yo guhura hagati yabatwara hanze no kugabanuka kwamashanyarazi. imikorere yumuhuza.Byongeye kandi, niba umuhuza wa coaxial ya RF ukoreshwa mubidukikije bikaze, nyuma yigihe runaka, igicucu cyumukungugu kizashyirwa kumaso yanyuma yumuyoboro winyuma.Iki gipimo cyumukungugu gitera guhuza imiyoboro hagati yabatwara hanze kwiyongera cyane, igihombo cyo kwinjiza umuhuza kiriyongera, kandi icyerekezo cyamashanyarazi kigabanuka.
Ingamba zogutezimbere: kugirango twirinde guhura nabi numuyoboro winyuma uterwa no guhindagurika cyangwa kwambara gukabije kwi sura ihuza, kuruhande rumwe, dushobora guhitamo ibikoresho bifite imbaraga nyinshi zo gutunganya umuyobozi winyuma, nkumuringa cyangwa ibyuma bidafite ingese;Kurundi ruhande, uburebure bwurukuta rwumuhuza wanyuma wumuyoboro winyuma nawo urashobora kongerwa kugirango wongere aho uhurira, kugirango igitutu kumwanya wigice cyumuhuza wanyuma wumuyoboro winyuma uzagabanuka mugihe kimwe guhuza torque irakoreshwa.Kurugero, umuhuza wa SMA coaxial watezimbere (SuperSMA ya SOUTHWEST Company muri Reta zunzubumwe zamerika), diameter yo hanze yinkunga yayo yo hagati ni Φ 4.1mm yagabanutse kugera kuri 3.9mm, uburebure bwurukuta bwubuso buhuza umuyoboro winyuma bwiyongera. kugeza 0.35mm, kandi imbaraga za mashini ziratera imbere, bityo bikazamura ubwizerwe bwihuza.Mugihe ubitse kandi ukoresha umuhuza, komeza uhuze isura yanyuma yumurongo winyuma.Niba hari umukungugu, uhanagure umupira wa pamba.Twabibutsa ko inzoga zitagomba gushirwa mubufasha bwitangazamakuru mugihe cyo guswera, kandi umuhuza ntagomba gukoreshwa kugeza inzoga zidahindagurika, bitabaye ibyo inzitizi zumuhuza zizahinduka kubera kuvanga inzoga.
2. Kunanirwa guterwa no guhura nabi nuyobora imbere
Ugereranije nuyobora hanze, umuyobozi wimbere ufite ubunini buto nimbaraga nke birashoboka cyane ko bitera umubonano mubi kandi biganisha kubihuza.Ihuza rya elastike rikoreshwa kenshi hagati yimyitwarire yimbere, nka sock slotted elastique ihuza, guhuza claw elastike ihuza, inzogera ihuza elastike, nibindi. intera.
Ingamba zogutezimbere: Turashobora gukoresha imbaraga zo gushiramo nimbaraga zo kugumana pin isanzwe ya gauge hamwe nuyobora muri sock kugirango tumenye niba guhuza soketi na pin bifite ishingiro.Kubihuza N-bwoko, diameter Φ 1.6760 + 0.005 Imbaraga zo gushiramo mugihe pin isanzwe ya guge ihuye na jack igomba kuba ≤ 9N, mugihe diameter Φ 1.6000-0.005 pin isanzwe hamwe nuyobora muri sock igomba kugira imbaraga zo kugumana ≥ 0.56N.Kubwibyo, turashobora gufata imbaraga zo gushiramo nimbaraga zo kugumana nkigipimo cyo kugenzura.Muguhindura ingano no kwihanganira sock na pin, kimwe nuburyo bwo gusaza bwo kuvura umuyoboro wa sock, imbaraga zo kwinjiza nimbaraga zo kugumana hagati ya pin na sock biri murwego rukwiye.
3. Kunanirwa guterwa no kunanirwa inkunga ya dielectric kugirango ushyigikire neza imbere
Nkigice cyingenzi cyumuhuza wa coaxial, inkunga ya dielectric igira uruhare runini mugushyigikira umuyobozi wimbere no kwemeza isano iri hagati yimyitwarire yimbere ninyuma.Imbaraga za mashini, coefficente yo kwagura amashyuza, guhora dielectric, ibintu bitakaza, kwinjiza amazi nibindi biranga ibikoresho bigira ingaruka zikomeye kumikorere yumuhuza.Imbaraga zihagije zihagije nicyo kintu cyibanze gisabwa kubufasha bwa dielectric.Mugihe cyo gukoresha umuhuza, inkunga ya dielectric igomba kwihanganira umuvuduko wa axial uva kumuyoboro w'imbere.Niba imbaraga za mashini zinkunga ya dielectric ari mbi cyane, bizatera deformasiyo cyangwa byangiritse mugihe cyo guhuza;Niba coefficente yo kwagura ubushyuhe bwibikoresho ari nini cyane, mugihe ubushyuhe bwahindutse cyane, inkunga ya dielectric irashobora kwaguka cyangwa kugabanuka cyane, bigatuma umuyobozi wimbere arekura, akagwa, cyangwa akagira umurongo utandukanye nuyobora hanze, kandi bigatera no ingano yicyambu gihuza guhinduka.Nyamara, kwinjiza amazi, guhora dielectric hamwe nigihombo bigira ingaruka kumikorere yamashanyarazi nkumuhigo winjizamo hamwe na coefficient de reaction.
Ingamba zogutezimbere: hitamo ibikoresho bikwiye kugirango utunganyirize urwego ruciriritse ukurikije ibiranga ibikoresho byo guhuza nkibidukikije bikoreshwa hamwe ninshuro zakazi zikoreshwa zihuza.
4. Kunanirwa guterwa no guhagarika urudodo ntirwoherezwa kumuyobora hanze
Uburyo bukunze kugaragara muri uku kunanirwa ni ukugwa kumaboko ya screw, biterwa ahanini nigishushanyo kidafite ishingiro cyangwa gutunganya imiterere yimigozi ya screw hamwe nubushobozi buke bwimpeta ya snap.
4.1 Igishushanyo kidafite ishingiro cyangwa gutunganya imiterere ya screw
4.1.1 Igishushanyo mbonera cyangwa gutunganya imigozi ya screw sleave snap ring groove ntabwo bifite ishingiro
.
(2) Inguni idasobanutse hepfo ya groove;
(3) Chamfer nini cyane.

4.2 Ubudahangarwa bubi bwimpeta
4.2.1 Igishushanyo mbonera cya radiyo yerekana impeta idafite ishingiro
4.2.2 Gusaza bidafite ishingiro gushimangira impeta ya snap
4.2.3 Guhitamo ibikoresho bidakwiye impeta ya snap
4.2.4 Uruziga rwo hanze chamfer ya snap ring nini cyane.Iyi fomu yo kunanirwa yasobanuwe mu ngingo nyinshi
Dufashe N-ubwoko bwa coaxial umuhuza nkurugero, uburyo bwinshi bwo kunanirwa bwa screw-ihuza RF coaxial ihuza ikoreshwa cyane irasesengurwa.Uburyo butandukanye bwo guhuza bizanaganisha kuburyo butandukanye bwo gutsindwa.Gusa ukoresheje isesengura ryimbitse ryuburyo bukwiranye na buri buryo bwo gutsindwa, birashoboka kubona uburyo bunoze bwo kunoza ubwizerwe, hanyuma ugateza imbere iterambere rya RF coaxial.
