Umugozi wa Coaxial ukoreshwa mu kohereza ingufu za RF kuva ku cyambu kimwe cyangwa ibice ku bindi byambu / ibice bya sisitemu.Umugozi usanzwe wa coaxial ukoreshwa nkumurongo wa microwave coaxial.Ubu buryo bwinsinga busanzwe bufite imiyoboro ibiri muburyo bwa silindrike ikikije umurongo rusange.Byose bitandukanijwe nibikoresho bya dielectric.Mugihe gito, form ya polyethylene ikoreshwa nka dielectric, naho kuri frequency nyinshi ibikoresho bya Teflon birakoreshwa.
Ubwoko bwa kabili ya coaxial
Hariho uburyo bwinshi bwa kabili ya coaxial bitewe nubwubatsi bwa kiyobora nuburyo bwo gukingira bukoreshwa.Ubwoko bwa kabili ya Coaxial burimo umugozi wa coaxial usanzwe nkuko byasobanuwe haruguru kimwe na gaze yuzuye ya gaze ya gaze, insinga ya coaxial, hamwe na kabili ya kabili ikingira.
Intsinga ya coaxial yoroheje ikoreshwa mugutambuka kuri tereviziyo yakira antene hamwe na kanseri yo hanze ikozwe muri file cyangwa braid.
Kuri microwave yumurongo, umuyobozi winyuma arakomeye kandi dielectric izaba ikomeye.Mu nsinga zuzuye za gaze ya coaxial, umuyobozi wa centre akozwe mumashanyarazi yoroheje, kandi akoresha polytetrafluoroethylene.Azote yumye irashobora gukoreshwa nkibikoresho bya dielectric.
Muri coax isobanutse, insulator y'imbere izamurwa ikikije umuyobozi w'imbere.kuzenguruka umuyoboro ukingiwe no kuzenguruka iki cyuma gikingira.
Muri kabili ya coaxial ikingiwe kabiri, ibice bibiri byo kurinda mubisanzwe bitangwa mugutanga ingabo yimbere ninyuma yinyuma.Ibi birinda ibimenyetso kuri EMI nimirasire iyo ari yo yose ituruka kuri kabili igira ingaruka kuri sisitemu iri hafi.
Umurongo wa Coaxial uranga inzitizi
Ibiranga inzitizi ya kabili ya coaxial irashobora kugenwa ukoresheje formula ikurikira.
Zo = 138 / sqrt (K) * Log (D / d) Ohms
in,
K ni dielectric ihoraho ya insulator hagati yimbere ninyuma.D ni umurambararo wumuyoboro winyuma naho d ni diameter yumuyobora imbere.
Ibyiza cyangwa Ibyiza bya Coaxial Cable
Ibikurikira nibyiza cyangwa ibyiza byumugozi wa coaxial:
UeBitewe n'ingaruka zuruhu, insinga za coaxial zikoreshwa mugukoresha inshuro nyinshi (> 50 MHz) koresha umuringa wambitswe umuringa wikigo.Ingaruka yuruhu nigisubizo cyibimenyetso byinshi byikwirakwiza hejuru yinyuma yuyobora.Yongera imbaraga za kabili kandi igabanya ibiro.
Cable Umugozi wa kabili ugura make.
ConUmuyoboro winyuma muri kabili ya coaxial akoreshwa mugutezimbere no gukingira.Ibi birangizwa no gukoresha file ya kabiri cyangwa igipande cyitwa sheath (cyagenwe C2 mumashusho 1).Ikoti ikora nk'ingabo ikingira ibidukikije kandi ikozwe mu mugozi wa coaxial integral nka retardant.
TNtibishobora kwangizwa n urusaku cyangwa kwivanga (EMI cyangwa RFI) kuruta insinga zahujwe.
Ugereranije na joriji ihindagurika, ishyigikira uburyo bwogukwirakwiza ibimenyetso byinshi.
➨Byoroshye kurigata no kwaguka kubera guhinduka.
AllowsByemerera umuvuduko mwinshi, insinga ya coaxial ifite ibikoresho byiza byo gukingira.
Ibibi cyangwa ibibi bya Cable ya Caxial
Ibikurikira nibibi byumugozi wa coaxial:
Size Ingano nini.
Installation Intera ndende kwishyiriraho irazimvye kubera ubunini bwayo no gukomera.
InceKubera ko umugozi umwe ukoreshwa mu kohereza ibimenyetso murusobe, niba umugozi umwe unaniwe, umuyoboro wose uzamanuka.
Umutekano uhangayikishijwe cyane kuko byoroshye gutega amatwi umugozi wa coaxial ukamena ukanashyiramo T-umuhuza (ubwoko bwa BNC) hagati yombi.
➨Bigomba gushingirwaho kugirango wirinde kwivanga.
