RF coaxial connectors zvinhu zvakakosha zvekufambisa-frequency signal transmission, uye iko kurongeka kwemagadzirirwo azvo ekugadzira kunokanganisa zvakanangana nemhando yemidziyo. Kubva pakusarudzwa kwezvinhu zvakasvibirira kusvika pakuyedzwa kwechigadzirwa chekupedzisira, nhanho yega yega inoda kudzora kwakasimba kwehunyanzvi paramita. Iyo inotevera inotsanangura iyo core production process.
1. Kugadzirira uye Kugadziriswa Kwezvinhu
Muchikamu chekutanga chekugadzira, -zvinoita copper alloy yakakwirira (seberyllium copper kana tin-phosphor bronze) inosarudzwa sechinhu chikuru. Iyo yekunze conductor inowanzoputirwa negoridhe kana sirivheri kudzikisa kubata kuramba. Insulating material inowanzonzi polytetrafluoroethylene (PTFE) kana ceramic{{4}based composites uye inofanira kuomeswa munzvimbo isingachinji yetembiricha uye mwando kuitira kuti pave nehunyoro huri pasi pe0.05%. Zvikamu zvakakosha, senge yepakati kuonana, inopinda inotonhora musoro. Izvi zvinosanganisira kutsika tsvimbo kuita cylindrical shape ine dhayamita chaiyo kuburikidza nedhiya, kuisa hwaro hwekuzotevera kugadzirisa.
2. Precision Machining
Iyo yepakati conductor inomisikidzwa kusvika kumamicron mazinga uchishandisa CNC lathe, ichiwana kushata kwepamusoro kweRa0.2μm kana kushomeka, ine kiyi yedimensional kushivirira inochengetwa mukati ± 0.005mm. Imba yekunze kondakita inogayiwa neCNC kugadzira shinda dzemukati uye migoro, pachishandiswa maturusi ecarbide epamusoro-kucheka nekumhanya kunodarika 20,000 rpm. Iyo insulating tsigiro inoumbwa uchishandisa chaiyo jekiseni rekuumba muchina, ine mold tembiricha inodzorwa pa180±5 dhigirii kuti ive nechokwadi chekuzadza yunifomu yePTFE cavity isina mabhuru emhepo.
3. Surface Treatment uye Electroplating
Zvese zvikamu zvesimbi zvinopinda katatu ultrasonic yekuchenesa cycles kubvisa oiri uye zvinosvibisa, zvichiteverwa nekunetseka kudzoreredza annealing kubvisa kusara kunetseka kubva kumachining. Iyo electroplating muitiro inoshandisa otomatiki kugadzirwa mutsetse, kutanga nickel base jasi (ukobvu Hukuru kupfuura kana kuenzana 3μm), inoteverwa negoridhe plating (ukobvu 0.5-1.0μm) kana sirivheri plating (ukobvu 5-8μm). Iyo tembiricha yekugezesa yekugezera inodzorwa zvakanyanya pa50±2 degree, uye density iripo inochengetwa pa2-3A/dm². Zvibatanidza zvekushandisa munzvimbo dzakakosha zvinogona zvakare kuda kuwedzera passivation kana conductive oxide layer.
4. Component Assembly Process
Kugadzira gungano kunoitwa mukamuri yekuchenesa yeKirasi 100, uye vashandi vanosungirwa kupfeka -mbatya dzisingachinji. Chekutanga, insulator inotsikirirwa mukati mepositioning groove yemba, iine tembiricha ye ±1 dhigirii kana yakachengetedzwa nekupisa-kunamira kwekunyungudika. Iyo yepakati conductor inopindirana nerutsigiro rwekudzivirira uchishandisa chitubu chekubata, uye laser alignment gauge inoshandiswa kutarisa coaxiality kukanganisa (Isingasviki kana kuenzana ne0.01mm). Iyo shoma shoma yesilicone girisi inoiswa kune yakarukwa yekubatanidza kuderedza kuisa simba. Pakupedzisira, imba yacho yakavharwa uchishandisa yakatsaurirwa crimping muchina, ine crimping simba rinodzorwa mukati meiyo 50-80N.
5. Performance Testing uye Quality Control
Chigadzirwa chakapedzwa chinopinda maitiro ekuongorora akazara: VSWR (voltage stand wave ratio) inoedzwa uchishandisa network analyzer, ine chinodiwa Chisingasviki kana kuenzana ne1.15 mukati me20GHz frequency band. Kuramba kubata kunopimwa pachishandiswa nzira ina-yewaya, ine hukoshi hwemazuva ese<5mΩ. Durability testing includes checking contact wear after 500 plug-in and unplug cycles, and a 96-hour salt spray test to assess corrosion resistance. All data is recorded in real time through the MES system, keeping the defective rate below 0.3%.
Yemazuva ano RF yekubatanidza kugadzirwa yakadzamisa yakanyatso kusanganisa kugadzira nehunyanzvi hwekuongorora matekinoroji. Kuunzwa kwemaitiro epamberi senge muchina kuona kwekuongorora uye kuchenesa plasma kunowedzera kuwedzera kuenderana kwechigadzirwa uye kuvimbika. Nekuvandudzwa kwe5G communications uye millimeter-wave tekinoroji, kudiwa kwemaminiaturized and high-frequency connectors kuri kufambisa magadzirirwo ekugadzira kuenda nanometer{5}}level chaiyo.
