Umsebenzi weCoaxial Cable

Intambo ye-coaxial yenziwe ngabaqhubi ababini. Intambo esembindini yentambo yeCoaxial isetyenziselwa ukuhambisa imiqondiso. Umnatha wokukhusela isinyithi udlala iindima ezimbini: enye intambo yomhlaba oqhelekileyo njengomqondiso wokubonelela nge-loop yangoku yomqondiso; enye ngumnatha okhuselayo njengomqondiso wokucinezela ukuphazamiseka kwengxolo ye-electromagnetic kwisignali.I-conductor yeziko kunye ne-mesh yekhaka iphakathi kwe-semi-foamed polypropylene insulating layer, emisela iimpawu zokudluliselwa kwentambo kunye nokukhusela ngokufanelekileyo umbindi. umqhubi.

Iintambo ze-coaxial zisetyenziswa ngokubanzi kwi-audio-video okanye ukuhanjiswa kwe-RF. I-impedance yokudluliselwa ngokubanzi yi-75_, eye yaba yintsilelo esemgangathweni yokuhanjiswa kwevidiyo (kwiintsuku zokuqala, i-50_ impedance yayisetyenziselwa ukuhanjiswa kwevidiyo) . iipropati kunye nokusebenza okuphezulu kweaudio kunye nevidiyo.I-frequency, isisombululo sesignali kunye nomgama osebenzayo wokuhambisa intambo idlala indima ecacileyo kwinkqubo yomsindo kunye nevidiyo.

Ukongezelela, kufuneka kuqatshelwe ukuba ukuze kugcinwe iimpawu zombane ezichanekileyo zentambo ye-coaxial, i-cable shielding layer kufuneka ibekwe phantsi.Ngexesha elifanayo, kufuneka kubekho ii-terminals kuzo zombini iziphelo zokunciphisa umphumo wokubonakalisa umqondiso.

Indlela yokufaka:

Iintambo ze-coaxial zifakelwa ngokubanzi phakathi kwesixhobo.Isinxibelelanisi sixhotyiswe kwindawo nganye yomsebenzisi ukubonelela ngojongano lomsebenzisi.Ujongano lufakwe ngolu hlobo lulandelayo:

(1) umgca olungileyo

Sika intambo kwaye uncamathisele iziphelo ze-BNC kuzo zombini iziphelo zentambo, emva koko uqhagamshele kuzo zombini iziphelo zesinxibelelanisi se-T.

(2) intambo engqindilili

Intambo engqindilili ifakwe ngokuqhelekileyo kusetyenziswa isixhobo esifana ne-TAP, esisebenzisa isikhonkwane sesikhokelo kwi-TAP ukungena kwi-insulation layer yentambo kwaye idibanise ngqo kwi-conductor.I-Terminators zicwangciswe kuzo zombini iziphelo zentambo ukunciphisa ukubonakaliswa yemiqondiso.
