Kusarudzwa kweRF coaxial connectors kunofanira kufunga nezvese zvinodiwa zvekuita uye zvehupfumi zvinhu.Kuita kunofanirwa kusangana nezvinodiwa zvehurongwa hwemagetsi emagetsi.Nezvehupfumi, inofanirwa kusangana nezvinodiwa zvekukosha engineering.In musimboti, zvinotevera zvinhu zvina zvinofanira kutariswa pakusarudza connectors.Tevere, ngatitarisei.
BNC connector
(1) Connector interface (SMA, SMB, BNC, nezvimwewo)
(2) Kuita kwemagetsi, tambo uye tambo kusangana
(3) Kugumisa fomu (PC bhodhi, tambo, mapaneru, nezvimwewo)
(4) Mechanical chimiro uye kupfeka (mauto uye kutengeserana)
1, Connector interface
Iyo yekubatanidza interface inowanzo tsanangurwa nekushandiswa kwayo, asi inofanirwa kusangana nemagetsi uye mechanical kuita zvinodiwa panguva imwe chete.
BMA mhando yekubatanidza inoshandiswa ku bofu kubatana kweyakaderera simba microwave system ine frequency kusvika 18GHz.
BNC connectors ndeye bayonet-mhando yekubatanidza, iyo inonyanya kushandiswa kuRF yekubatanidza nefrequency yakaderera pane 4GHz, uye inoshandiswa zvakanyanya mumatiweki masisitimu, zviridzwa uye komputa yekubatanidza minda.
Kunze kweiyo screw, iyo interface yeTNC yakafanana neiyo yeBNC, iyo inogona kushandiswa pa11GHz uye ine mashandiro akanaka pasi pemamiriro ekudengenyeka.
SMA screw connectors anoshandiswa zvakanyanya mundege, radar, microwave kutaurirana, kutaurirana kwedhijitari uye mamwe mauto nevagari minda.Impedance yayo ndeye 50 Ω.Paunenge uchishandisa flexible cable, frequency yakaderera pane 12.4GHz.Paunenge uchishandisa semi-rigid tambo, iyo yakanyanya frequency ndeye 26.5GHz.75 Ω ine tarisiro yakafara yekushandisa mukukurukurirana kwedhijitari.
Huwandu hweSMB idiki pane yeSMA.Kuti uise yekuzvivharira chimiro uye kufambisa kukurumidza kubatanidza, iyo yakajairika application kutaurirana kwedhijitari, kunova kutsiva kweL9.Iyo yekutengesa 50N inosangana ne4GHz, uye 75 Ω inoshandiswa ku2GHz.
SMC yakafanana neSMB nekuda kwescrew yayo, iyo inova nechokwadi chekuita kwakasimba kwemuchina uye yakafara frequency renji.Inonyanya kushandiswa mumauto kana yakakwirira vibration nharaunda.
N-mhando screw connector inoshandisa mweya se insulating material ine mutengo wakaderera, impedance ye50 Ω uye 75 Ω, uye frequency inosvika 11 GHz.Inowanzo shandiswa mumatunhu network, midhiya kutapurirana uye bvunzo zviridzwa.
Iyo MCX uye MMCX yakatevedzana majoini akapihwa neRFCN madiki muhukuru uye akavimbika mukubata.Ndivo zvigadzirwa zvinosarudzika kusangana nezvinodiwa zveyakadzika uye miniaturization, uye zvine tarisiro yakafara yekushandiswa.
2, Kuita kwemagetsi, tambo uye tambo kusangana
A. Impedance: The connector inofanira kufanana ne impedance ye system uye cable.Izvo zvinofanirwa kucherechedzwa kuti haazi ese ekubatanidza anosanganisirwa anosangana neiyo impedance ye50 Ω kana 75 Ω, uye iyo impedance mismatch inotungamira kune system kuita kudzikira.
B. Voltage: iva nechokwadi chokuti iyo yakanyanya kumira voltage yekubatanidza haigoni kudarika panguva yekushandiswa.
C. Maximum kushanda frequency: imwe neimwe yekubatanidza ine yakanyanya kushanda frequency limit, uye mamwe ekutengesa kana 75n magadzirirwo ane mashoma ekushanda frequency muganhu.Pamusoro pekushanda kwemagetsi, imwe neimwe yemhando yemhando ine maitiro ayo akasiyana.Semuenzaniso, BNC ndeye bayonet yekubatanidza, iyo iri nyore kuisa uye yakachipa uye yakashandiswa zvakanyanya mukuderera-kuita kwemagetsi kubatana;SMA uye TNC akateedzana akabatana nenzungu, achisangana nezvinodiwa zveyakakwira vibration nharaunda pane zvinobatanidza.SMB ine basa rekukurumidza kubatanidza uye kudzima, saka iri kuwedzera kufarirwa nevashandisi.
D. Cable: Nemhaka yekushanda kwayo kwekudzivirira kwekudzivirira, tambo yeTV inowanzoshandiswa mumasitimu anongofunga nezvekuvhiringidza.Iyo yakajairika application iTV antenna.
Iyo TV inochinjika tambo yakasiyana yeTV tambo.Iyo ine inoenderera mberi impedance uye yakanaka yekudzivirira maitiro.Inogona kukotama uye ine mutengo wakaderera.Inoshandiswa zvakanyanya muindasitiri yemakomputa, asi haigone kushandiswa mumasisitimu anoda kukwirira kwekudzivirira kuita.
Shielded flexible cables anobvisa inductance uye capacitance, iyo inonyanya kushandiswa muzviridzwa uye zvivakwa.
Flexible coaxial tambo yave yakanyanya kuvharika yakavharwa tambo nekuda kwekuita kwayo kwakakosha.Coaxial zvinoreva kuti chiratidzo uye pasi conductor zviri paakisi imwe chete, uye yekunze conductor inoumbwa newaya yakarukwa, saka inonzi zvakare yakarukwa coaxial tambo.Iyi tambo ine yakanaka yekudzivirira mhedzisiro pane yepakati conductor uye kudzivirira kwayo kunoenderana nerudzi rwewaya yakarukwa uye ukobvu hweakarukwa layer.Kuwedzera kune yakakwira voltage kuramba, iyi tambo yakakodzerawo kushandiswa pakakwirira frequency uye yakakwirira tembiricha.
Semi-rigid coaxial tambo dzinotsiva iyo yakarukwa layer netubular shells, inonyatso gadzira iyo yekushata kwekushomeka kwekudzivirira mhedzisiro yetambo dzakarukwa pamhepo huru.Semi-rigid cables anowanzo shandiswa pakakwirira.
E. Cable assembly: Pane nzira mbiri huru dzekuisa connector: (1) welding the central conductor and screwing the shielding layer.(2) Cheka chepakati conductor uye shielding layer.Dzimwe nzira dzinotorwa kubva kune nzira mbiri dziri pamusoro, dzakadai sewelding yepakati conductor uye crimping shielding layer.Nzira (1) inoshandiswa mumamiriro ezvinhu asina maturusi ekuisa;Nekuda kwekushanda kwakanyanya uye kwakavimbika kumisa kuita kweiyo crimping dhizaini, uye dhizaini yeakakosha crimping chishandiso inogona kuona kuti imwe neimwe tambo magot chikamu chakaunganidzwa chakafanana, nekuvandudzwa kwechishandiso chinodhura chegungano, crimping shielding layer. yewelding centre conductor ichawedzera kufarirwa.
3, Kugumisa fomu
Zvibatanidza zvinogona kushandiswa kune RF coaxial tambo, akadhindwa edunhu mabhodhi uye mamwe maratidziro ekubatanidza.Kudzidzira kwakaratidza kuti imwe mhando yekubatanidza inoenderana neimwe mhando yetambo.Kazhinji, tambo ine dhayamita diki yekunze yakabatana nediki coaxial connectors seSMA, SMB uye SMC.4, Mechanical chimiro uye kupfeka
Chimiro chekubatanidza chichakanganisa zvikuru mutengo wayo.Dhizaini yekubatanidza yega yega inosanganisira chiyero chemauto uye chiyero chekutengesa.Chiyero chemauto chinogadzira zvese zvikamu zvemhangura, polytetrafluoroethylene insulation, uye yemukati uye yekunze goridhe-plating zvinoenderana neMIL-C-39012, ine yakanyanya kuvimbika kuita.Commerce yakajairika dhizaini inoshandisa zvakachipa zvinhu zvakaita sekukanda ndarira, polypropylene insulation, sirivheri coating, nezvimwe.
Zvibatanidza zvinogadzirwa nendarira, beryllium mhangura uye simbi isina tsvina.Iyo yepakati conductor inowanzo putirwa negoridhe nekuda kwekushomeka kwayo, corrosion resistance uye yakanakisa mhepo.Chiyero chemauto chinoda kuputirwa negoridhe paSMA neSMB, uye sirivheri yekuisa paN, TNC uye BNC, asi vashandisi vazhinji vanosarudza nickel plating nekuti sirivha iri nyore kuita oxidize.
Iyo inowanzo shandiswa yekubatanidza insulators inosanganisira polytetrafluoroethylene, polypropylene uye toughened polystyrene, iyo polytetrafluoroethylene ine yakanyanya kunaka insulation performance asi yakakwira mutengo wekugadzira.
Zvinhu uye chimiro chekubatanidza zvinokanganisa kuoma kwekugadzirisa uye kushanda kwechibatanidza.Naizvozvo, vashandisi vanofanirwa kusarudza zvine hungwaru nekuita zvirinani uye mutengo reshiyo zvinoenderana nenharaunda yavo yekushandisa.
