Kev paub txog kev sib txuas: Qhov kev ua tau zoo ntawm cov khoom sib txuas tuaj yeem muab faib ua peb pawg tseem ceeb: kev ua haujlwm zoo, hluav taws xob ua haujlwm, thiab kev ua haujlwm ib puag ncig.
1. Mechanical Performance
Nyob rau hauv cov nqe lus ntawm kev sib txuas muaj nuj nqi, insertion thiab extraction quab yuam yog ib qho tseem ceeb mechanical kev ua tau zoo yam ntxwv. Insertion thiab extraction quab yuam yog muab faib ua insertion force thiab extraction force (tseem hu ua kev sib cais quab yuam), thiab qhov yuav tsum tau muaj rau ob qhov sib txawv. Cov txheej txheem tsim nyog tau teev tseg qhov siab tshaj plaws kev quab yuam thiab kev sib cais tsawg kawg nkaus, qhia tau hais tias los ntawm kev pom kev siv, lub zog ntxig yuav tsum qis (li no qhov muaj qhov qis qis qis (LIF) thiab xoom ntxig quab yuam (ZIF) cov qauv), thaum lub zog sib cais tsawg dhau yuav cuam tshuam qhov kev ntseeg tau ntawm kev sib cuag. Kev siv lub zog thiab kev tshem tawm thiab lub neej txhua yam ntawm cov khoom sib txuas yog cuam tshuam nrog cov qauv kev sib cuag (qhov loj ntawm lub zog ib txwm), qhov zoo ntawm plating ntawm cov ntsiab lus sib cuag (coefficient ntawm zawv zawg kev sib txhuam), thiab qhov tseeb qhov tseeb ntawm kev sib cuag (kev sib haum xeeb).
2. Kev ua haujlwm hluav taws xob
Lub ntsiab hluav taws xob kev ua tau zoo ntawm cov connectors muaj xws li kev tiv thaiv, rwb thaiv tsev tsis kam, thiab dielectric zog.
ib. Kev Tiv Thaiv Kev Tiv Thaiv: Siab - cov khoom siv hluav taws xob zoo yuav tsum muaj kev tiv thaiv qis thiab ruaj khov. Kev sib cuag tsis kam ntawm cov khoom sib txuas ntawm ob peb milliohms mus rau kaum milliohms.
b. Rwb thaiv tsev tiv thaiv ntsuas qhov kev ua tau zoo ntawm rwb thaiv tsev ntawm kev sib txuas thiab nruab nrab ntawm kev sib cuag thiab lub plhaub, xws li ntau pua megohms mus rau ntau txhiab megohms.
c. Dielectric zog, tseem hu ua withstand voltage los yog dielectric withstand voltage, characterizes lub connector lub peev xwm los tiv thaiv qhov ntsuas ntsuas voltage ntawm kev sib cuag los yog nruab nrab ntawm kev sib cuag thiab lub plhaub.
d. Lwm yam kev ua tau zoo ntawm hluav taws xob.
Electromagnetic cuam tshuam los ntawm attenuation ntsuam xyuas cov connector lub electromagnetic cuam tshuam shielding efficiency, feem ntau kuaj nyob rau hauv lub 100MHz mus rau 10GHz zaus ntau.
Rau RF coaxial connectors, kuj tseem muaj cov ntsuas hluav taws xob xws li cov yam ntxwv impedance, qhov poob qis, kev cuam tshuam coefficient, thiab voltage sawv yoj piv (VSWR). Vim yog txoj kev loj hlob ntawm cov thev naus laus zis thev naus laus zis, ib hom tshiab txuas, lub siab -ceev teeb liab txuas, tau tshwm sim rau kev sib txuas thiab xa tawm siab - ceev digital mem tes signals. Raws li txoj cai, nyob rau hauv cov nqe lus ntawm hluav taws xob kev ua tau zoo, ntxiv rau cov yam ntxwv impedance, tshiab hluav taws xob ntsuas tau tshwm sim, xws li crosstalk, kis tau tus mob ncua, thiab skew.
3. Kev ua haujlwm ib puag ncig
Cov yam ntxwv ntawm ib puag ncig kev ua tau zoo xws li kub tsis kam, av noo tsis kam, ntsev tsuag tsis kam, kev co, thiab kev poob siab.
ib. Kub Resistance: Tam sim no, qhov siab tshaj plaws kev khiav hauj lwm kub rau connectors yog 200℃(tshwj tsis yog rau ob peb siab -kub tshwj xeeb connectors), thiab qhov qis tshaj yog -65℃. Txij li thaum tam sim no generates tshav kub ntawm cov ntsiab lus sib cuag thaum lub sij hawm connector ua hauj lwm, ua rau ib tug kub nce, qhov kev khiav hauj lwm kub yog feem ntau suav hais tias yog cov sum ntawm lub ambient kub thiab qhov sib cuag kub nce. Qee qhov kev qhia tshwj xeeb qhia meej meej txog qhov siab tshaj qhov tso cai qhov kub ntawm qhov sib txuas hauv qab ntsuas kev ua haujlwm tam sim no.
b. Moisture Resistance: Moisture intrusion tuaj yeem cuam tshuam rau kev ua haujlwm rwb thaiv tsev ntawm cov khoom txuas thiab corrode hlau qhov chaw. Cov av tsis tu ncua thiab ntsuas kub yog 90% ~ 95% txheeb ze av noo (txog 98% raws li cov khoom tshwj xeeb), kub +40± 20 degree, thiab lub sijhawm ntsuas raws li cov khoom teev tseg, nrog tsawg kawg ntawm 96 teev. Hloov cov av noo thiab ntsuas cua sov yog qhov nruj dua.
c. Salt Spray Resistance: Thaum cov khoom sib txuas ua haujlwm nyob rau hauv ib puag ncig uas muaj cov dej noo thiab ntsev, electrochemical corrosion kuj yuav tshwm sim ntawm cov txheej txheem kho cov hlau ntawm lawv cov khoom siv hlau thiab kev sib cuag, cuam tshuam rau lub cev thiab hluav taws xob kev ua haujlwm ntawm lub connector. Txhawm rau ntsuas lub peev xwm ntawm cov khoom siv hluav taws xob los tiv thaiv ib puag ncig zoo li no, kev ntsuas ntsev ntsev tau teev tseg. Qhov no suav nrog kev tshem tawm cov khoom sib txuas hauv qhov kub thiab txias -chamber kuaj thiab tshuaj tsuag nrog cov cua compressed siv cov tshuaj sodium chloride ntawm ib qho kev qhia tshwj xeeb los tsim kom muaj cov tshuaj tsuag ntsev. Lub sij hawm raug tau teev nyob rau hauv cov khoom specification thiab yuav tsum yog tsawg kawg yog 48 teev.
d. Kev co thiab kev poob siab: Kev vibration thiab kev poob siab yog qhov tseem ceeb ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog tseem ceeb hauv kev siv tshwj xeeb xws li aerospace, rail, thiab kev thauj mus los. Lawv yog cov cim tseem ceeb ntawm lub zog ntawm lub connector tus neeg kho tshuab qauv thiab kev ntseeg siab ntawm nws cov hluav taws xob tiv tauj. Cov kev sim tshwj xeeb qhia meej meej cov yam ntxwv no. Kev ntsuam xyuas kev poob siab yuav tsum qhia meej txog qhov ceev ceev, lub sijhawm, thiab kev poob siab pulse waveform, nrog rau lub sijhawm ntawm kev cuam tshuam hluav taws xob txuas ntxiv.
e. Lwm yam kev ua tau zoo ib puag ncig: Nyob ntawm daim ntawv thov, lwm yam kev ua tau zoo ib puag ncig ntawm cov khoom siv hluav taws xob muaj xws li kev sib khi (cua pa, kua siab), kua immersion (ua haujlwm rau degradation los ntawm cov kua dej tshwj xeeb), thiab qis -siab tsis kam.
