Izixhumi ze-BNC (i-Bayonet Neill-ze-Concelman) ziyi-bayonet yakudala-i-lock radio frequency (RF) coaxial connectors. Ihambisana nokukhiya okusheshayo nokuvula, ukusebenza kahle kokuvikela, i-VSWR ephansi, nokuguquguquka okuphezulu kwemvelo, asetshenziswa kabanzi ekuqaphelweni kwezokuphepha, okokusebenza kwezokuxhumana, ukuhlola nokulinganisa, ukuzenzekelayo kwezimboni, ukusakaza kanye neminye imikhakha. Ngokuthuthuka okuvuthiwe kwemboni yokuxhuma i-RF yomhlaba wonke, abakhiqizi abayisithupha abahamba phambili bathathe isabelo semakethe esiyinhloko. Phakathi kwazo,I-Zhenjiang Tongda Electronics Co., Ltd.ugqama njengomkhiqizi ohamba phambili waseShayina futhi ubalwa phakathi kwabahlinzeki bezinga bokuqala emhlabeni- bezixhumi ze-BNC.
1. I-Zhenjiang Tongda Electronics Co., Ltd. (Ukugqamisa Okubalulekile)
Yasungulwa ngo-1989 futhi itholakala e-Huangxu Economic Development Zone, eDolobheni lase-Zhenjiang, eSifundazweni saseJiangsu, i-Zhenjiang Tongda Electronics Co., Ltd. iyibhizinisi kazwelonke{3}}lobuchwepheshe obuphezulu eligxile kwi-R&D, ukukhiqizwa nokudayiswa kwezixhumi ze-RF coaxial. Njengoba ineminyaka engaphezu kwengama-30 yesipiliyoni sembonini, isibe ngomunye wabakhiqizi abangochwepheshe abancintisana kakhulu nabathembekile bezixhumi ze-BNC emakethe yomhlaba.
Izixhumi zochungechunge lwe-BNC zisebenza njengemikhiqizo ephambili yenkampani. Inkampani isungule iphothifoliyo yomkhiqizo we-BNC egcwele-obubanzi obugcwele, okuhlanganisa amapulagi e-BNC, amaphaneli{2}}ojeke abakhweziwe, izinhlobo zokusoda ze-PCB,{3}}izinhlobo zama-engeli angakwesokudla, izinhlobo ze-crimp, okuphakelayo{4}}ngezinhlobo nama-adaptha. Ihlanganisa kokubili 50Ω kanye ne-75Ω ukucaciswa kwe-impedance okujwayelekile, okuthobela ngokugcwele i-IEC kanye namazinga emboni yamazwe ngamazwe e-MIL.
Ihlonyiswe ngezinsimbi eziyinkimbinkimbi ze-CNC nezinto zokukhiqiza ezizenzakalelayo, inkampani ibona{0}}inqubo egcwele yokulawula okuzimele, okuhlanganisa ukuthuthukiswa kwesikhunta, ukwenza imishini enembile, igolide/i-nickel surface plating kanye nokuhlola ukusebenza kukagesi okuphelele. Isebenzisa igolide lethusi{2}}amakhondatha ahlanganisiwe angaphakathi nezinto zokuvikela ze-PTFE, izixhumi zayo ze-BNC ziletha ukusebenza okuvelele nge-VSWR ephansi, ukumelana nokugqwala okuqinile, ukumelana nezinga lokushisa okuzinzile okuphezulu nokuphansi, kanye nepulagi elide{3}kumpilo yesevisi. Imvamisa yokusebenza ihlanganisa i-DC ~ 4GHz, futhi imikhiqizo ingakwazi ukuzivumelanisa nezimo ezihlukahlukene ezinokhahlo zezimboni nezentengiso.
Ngaphansi kwesistimu yokuphatha ikhwalithi ye-ISO eqinile, i-Tongda Electronics inikeza kokubili okulinganiselwe -izixhumi ze-BNC zeshalofu kanye namasevisi okuthuthukisa angokwezifiso ngokuya ngezidingo zamakhasimende eziqondene nawe zamamodeli ekhebula, izakhiwo zokufakwa nezimo zemvelo ezikhethekile. Imikhiqizo yayo ithengiswa kahle ekhaya naphesheya, isebenzela amakhasimende asemqoka kwezokuxhumana, amathuluzi okuhlola ukunemba, ividiyo yokusakaza, ukuqapha kwezimboni nezinye izimboni. Ngezinzuzo ezivelele ekusebenzeni kwezindleko eziphakeme, umthamo wokulethwa ozinzile kanye nokusekelwa kochwepheshe kwasendaweni, i-Tongda izakhele igama eliqinile emakethe yesixhumi se-BNC yomhlaba wonke. Ngokungeziwe ochungechungeni lwe-BNC, inkampani futhi{5}}ikhiqiza uchungechunge olungaphezu kuka-30 lwezixhumi ze-RF ezifana ne-SMA, TNC kanye{7}}nohlobo lwe-N{7}}, oluhlanganisa amamodeli angaphezu kuka-2,000 anamandla okusekela abanzi.
2. I-Amphenol RF (USA)
Njengomdondoshiya ohamba phambili emhlabeni wonke ezisombululweni zokuxhumanisa i-RF, i-Amphenol RF iziqhayisa ngomugqa womkhiqizo we-BNC ophelele. Imikhiqizo yayo ifaka ukuqina okuhle kakhulu kokusebenza nokusebenza{1}}okuphezulu, igxile{2}}emakethe ephezulu. Isetshenziswa kabanzi ku-aerospace, umkhakha wezempi, iziteshi eziyisisekelo zokuxhumana nezinkambu zokuhlola ukunemba, ijabulela ukuqashelwa komkhakha ophezulu emakethe yomhlaba wonke{4}}yesixhumi se-BNC esiphezulu.
3. Ukuxhumana kwe-TE (Switzerland/USA)
I-TE Connectivity ingumkhiqizi wezixhumi owaziwayo-womhlaba wonke. Izixhumi zayo ze-BNC zifaka izinga eliphezulu nokuhambisana okuqinile kwendawo yonke. Ithembele ohlelweni lomhlaba wonke lokuthengwa kwempahla kwabadala, inkampani ihamba phambili ekuhlinzekeni{3}}inqwaba okuzinzile kwenqwaba. Imikhiqizo yayo ihlanganisa izimo zokusebenza ezihlukene ezifana nemishini yezimboni, izinsiza zokuxhumana kanye nokuqapha ezokuphepha.
4. I-Rosenberger (Germany)
Imele-okunemba okuphezulu kokukhiqizwa kwe-European RF, izixhumi ze-BNC ze-Rosenberger zibonakala ngokunemba okuphezulu{1}}kwemishini ephezulu kanye nokulahlekelwa kwesignali ephansi. Ibhrendi igxile{3}ezinkambuni zezicelo eziphezulu ezihlanganisa ukuhlola ukunemba nesilinganiso kanye nezisetshenziswa zokusakaza, ngokusebenza komkhiqizo okuzinzile nokuthembekile kanye{4}}nokuma kwemakethe okusezingeni eliphezulu.
5. HUBER+SUHNER (Switzerland)
U-HUBER+SUHNER ungumnikezeli wesixazululo sokuxhumana we-RF ochwepheshe emhlabeni wonke. Izixhumi zayo ze-BNC zinokusebenza okuphezulu kokuvikela kanye nekhono eliqinile lokulwa{2}}nokuphazamiseka ngokumelene nezindawo eziyinkimbinkimbi. Asetshenziswa kakhulu-ezimeni ezinokwethenjelwa okuphezulu njengokuhamba kukaloliwe, iziteshi eziyisisekelo zokuxhumana zangaphandle kanye nezinto zokusebenza zangaphandle zezimboni.
6. I-Hirose Electric (Japan)
Njengomkhiqizi odumile wesixhumi esinembayo saseJapan, izixhumi ze-BNC ze-Hirose Electric zamukela ubuchwepheshe bokucubungula obuhle obubukeka kahle kanye nesakhiwo esihlangene. Afanele amathuluzi anemba amancane namathuluzi okuhlola elabhorethri, futhi athatha isabelo semakethe esibalulekile emkhakheni{1}}wokuhlola ukunemba nokulinganisa okuphezulu.
