SMA connector: tsanangudzo, chinangwa, kusarudzwa kwechigadzirwa

Shandisheni yeSMA yakagadziridzwa muna 1960 nekuda kwekwakagadzikana kabheji rainzi RG-402 (0.141 inch). Izvi zvinogadzirirwa kurwisana kwe50 ohms uye nguva inosvika kusvika 18 GHz (mumwe munhu akanyatsogadziriswa anokwanisa kushandiswa pazvikamu zvinosvika 26,5 GHz). Iko SMA connector ine 1 / 4-36 yakabatanidzwa yakabatana , kushandiswa kwemagetsi uye kuenzaniswa kwezvakagadzirwa. Iko inoshandiswa purogiramu inoshandiswa yekambo huni hunoenderana nerudzi rwetambo.

Kusarudzwa

I-high-frequency SMA connector ine ruzivo rwakakura kwazvo rwezvidzidzo, mitsara inokosha iyo ndiyo yakakura uye nguva inoparadzwa. Muzvikamu zvakasiyana-siyana zvemadhora, zviyero zvekuyera, zvigadzirwa zvekushandisa, uye mune mamwe majaira anoshandisa chiyero chekuenzanisa, zvakadaro sezvibatanidza zvemakumbo emakona ecoaxial, pamwe chete nema adapters (plug connectorors), inongova nzira yakakwana yekugadzirisa mashomanana.

Iko SMA connector, inogadzirwa maererano nezvinodiwa nehutano, inobatana nezvose zvinogadzirisa (pasinei nemhizha) iyo inosangana nemashoko aya uye inenge yakaenzana. Iyo inoshandiswa mumagetsi akawanda ewa microwave: microstrip uye coaxial-wave transitions, attenuators, amplifiers, master generator, switches, mixers uye filters.

Mhando dzekubatanidza

Kune mhando mbiri dzekubatana kweSMA: SMA ("socket" uye "plug") uye RP-SMA (zvakare "socket" uye "plug").

Mune midziyo isina tsvina (Wi-Fi access point, ma WiMAX, adapter), pane connector iyo antenna (SMA kana N-Type connector) yakabatana. Sezvo kubatana uku kunoumbwa nezvikamu zviviri, zvose zvibatanidza ne-threaded zvakagadzirwa ndezvipi zviviri, zvakabatanidzwa kune zvimwe: zvigaro nemapuchi. Icho chikonzero, iyo yekupedzisira inoputirwa mudendere. Izwi rokuti "amai", "jack" kana kuti "vakadzi" rinoshandiswa kuratidza chikwata, uye "baba", "plug" kana "murume" kwepombi.

Kune zvipembenene zvakasiyana-siyana uye adapta tambo pakati pemarudzi akasiyana evanhu vanobatanidza.

Rudzi rwechipiri rwekubatanidza i-RP-SMA connectors (ine reverse polarity kana inverse connectors). Mumakwikwi akadaro, zvakasiyana ndezvechokwadi: ipaki inobata zvigaro, asi zvigaro zvakasimbiswa. Muchibvumirano chakakanganiswa, sarudzo iri pakati pekubuda inoshandurwa.

Kuenzanisa kwekubatanidza

Nenzira yekubatanidza, zvibatanidza zviri mubvunzo zvakakamurwa kuva zvishandiso ne threaded and bayonet connection. Nenzira yekugadziriswa, zvibatanidza zvinoputika, zvinotengeswa uye zvinoputika. Maererano nekugadzira, pane zvakakosha, tambo, hurukuro yepamusoro inowanikwa pane bhidhiyo redhiro rakadhindwa , pamwe chete nemapapirita.

Zvigadzirwa zvemagetsi zvakagadzirirwa mumuviri ane square flange kana nut. Iyo kambo inosungirwa ne soldering kana kukomba. Kubatanidza kwakasungirirwa pabhodhi kunosanganiswa nekusungirirwa pasi kana kutenderera kusvika kumusoro. Ikokubatanidza hutambo inogadziriswa nekuputika kana kutengesa. Zvigadziri zvinoshandiswa kuunganidza marudzi akasiyana ehutachiona.

Mhedziso

Mukombiyuta yekombiyuta, SMA vatauri vakawana kushandiswa kwakazara musangano reantenas nokuda kwezvikwata zve Wi-Fi. Vanopa hutano hwakasimba, uyewo kuderedza kurasikirwa kunowanikwa pahutano hunoenderana. Izvo zvakakosha zvinokonzerwa nemakwikwi akadaro ndezvokugadzikana uye kurwisana nemitambo yemagetsi.
