[Cov Lus Qhia] Nyob rau theem no, txhawm rau txhawm rau ua kom muaj kev sib koom ua ke thiab kev sib koom ua ke siab ntawm lub tsheb hluav taws xob ua haujlwm, thiab kom ua tau raws li kev txhim kho ntawm cov khoom siv hluav taws xob tshiab ntse, feem ntau xaiv cov khoom sib txuas sib txuas muaj kev sib koom ua ke (tsis yog tsuas yog xa mus rau siab. tam sim no thiab siab zog, tab sis kuj yuav kis tau tus nqi qis thiab qis tam sim no analog teeb liab), xaiv ntau theem ntawm kev sib txuas cov qauv rau cov haujlwm sib txawv thiab cov haujlwm sib txawv los xyuas kom meej tias lub neej kev pab cuam ntawm lub connector yuav tsum tsis txhob qis dua qhov kev pab cuam lub neej. ntawm cov tsheb ib txwm muaj, nyob rau hauv qhov kev tso cai yuam kev Kev ruaj khov ntawm cov khoom siv hluav taws xob thiab cov cim qhia yuav tsum tau ua kom ntseeg tau;cov connectors yog txuas los ntawm terminals, thiab cov txiv neej thiab poj niam terminals yog ua los ntawm hlau conductive cov ntaub ntawv.Qhov zoo ntawm lub davhlau ya nyob twg txuas ncaj qha cuam tshuam rau kev ntseeg tau ntawm cov hluav taws xob ua haujlwm ntawm lub tsheb.
1 Kev Taw Qhia
Cov hlua khi hlua khi rau kev sib kis tam sim no nyob rau hauv lub tsheb xaim hlua txuas txuas feem ntau yog stamped los ntawm cov khoom siv tooj liab zoo.Ib feem ntawm cov terminals yuav tsum tau fastened mus rau lub plhaub yas, thiab lwm qhov yuav tsum tau hluav taws xob txuas mus rau mating terminals.Cov tooj liab alloy Txawm hais tias nws muaj cov khoom siv zoo, nws qhov kev ua tau zoo hauv hluav taws xob conductivity tsis txaus siab; Feem ntau, cov khoom siv hluav taws xob zoo muaj cov khoom siv nruab nrab, xws li tin, kub, nyiaj, thiab lwm yam.Yog li ntawd, plating yog qhov tsim nyog heev los muab cov terminals nrog cov khoom siv hluav taws xob thiab cov khoom siv kho tshuab tib lub sijhawm.
2 Hom Plating
Vim muaj cov haujlwm sib txawv ntawm cov terminals thiab qhov sib txawv siv ib puag ncig (siab kub, thermal voj voog, av noo, poob siab, kev vibration, plua plav, thiab lwm yam), qhov kev xaiv ntawm lub davhlau ya nyob twg plating kuj muaj ntau yam, feem ntau yog los ntawm qhov siab tshaj plaws nruam kub, plating thickness, tus nqi, pairing Qhov tsim nyog plating txheej ntawm mating davhlau ya nyob twg yog xaiv cov terminals nrog sib txawv plating txheej kom tau raws li qhov ruaj khov ntawm cov hluav taws xob muaj nuj nqi.
3 Kev sib piv ntawm Txheej Txheej
3.1 Tin-plated terminals
Tin plating feem ntau muaj kev ruaj ntseg zoo thiab tus nqi qis, yog li nws yog dav siv, thiab muaj ntau ntau cov tin plating txheej siv nyob rau hauv ntau yam, xws li tsaus tin, ci tin, thiab kub dip tin.Piv nrog rau lwm cov coatings, cov hnav tsis kam yog tsis zoo, tsawg dua 10 mating cycles, thiab kev sib cuag yuav txo nrog lub sij hawm thiab kub, thiab nws yog feem ntau siv nyob rau hauv ambient tej yam kev mob hauv qab no 125 ° C.Thaum tsim cov tin-plated terminals, kev sib tiv tauj siab thiab kev xaav me me yuav tsum raug txiav txim siab los xyuas kom meej qhov ruaj khov ntawm kev sib cuag.
3.2 Nyiaj Plated Terminals
Silver plating feem ntau muaj qhov zoo ntawm kev sib cuag, tuaj yeem siv tsis tu ncua ntawm 150 ° C, tus nqi kim dua, nws yooj yim rau xeb hauv huab cua nyob rau hauv muaj leej faj thiab chlorine, nyuaj dua tin plating, thiab nws cov resistivity yog me ntsis. siab dua los yog sib npaug rau tin , lub peev xwm electromigration phenomenon yooj yim ua rau muaj kev pheej hmoo ntawm cov khoom sib txuas.
3.3 Kub-plated terminals
Kub-plated terminals muaj kev sib cuag zoo thiab ib puag ncig kev ruaj ntseg, qhov kub tsis tu ncua tuaj yeem tshaj 125 ℃, thiab muaj kev sib txhuam zoo heev.Hard kub yog ib qho nyuaj tshaj li tin thiab nyiaj, thiab muaj kev sib txhuam zoo heev, tab sis nws cov nqi siab dua, thiab tsis yog txhua lub davhlau ya nyob twg xav tau kub plating.Thaum lub zog tiv tauj tsawg thiab cov tin plating txheej yog hnav, kub plating tuaj yeem siv tau.Terminal.
4 Qhov tseem ceeb ntawm Terminal Plating Application
Nws tuaj yeem tsis tsuas yog txo qhov corrosion ntawm lub davhlau ya nyob twg cov ntaub ntawv nto, tab sis kuj txhim kho lub zog ntxig lub xeev.
4.1 Txo kev sib txhuam thiab txo qis kev quab yuam
Lub ntsiab yam tseem ceeb uas cuam tshuam rau coefficient ntawm kev sib txhuam ntawm cov terminals muaj xws li: cov khoom, deg roughness, thiab deg kho.Thaum cov khoom siv davhlau ya nyob twg raug kho, qhov sib txhuam coefficient ntawm cov terminals yog tsau, thiab cov txheeb ze roughness kuj loj.Thaum lub npoo ntawm lub davhlau ya nyob twg raug kho nrog txheej txheej, cov khoom siv txheej txheej, txheej tuab, thiab txheej txheej tiav muaj qhov cuam tshuam zoo rau kev sib txhuam coefficient.
4.2 Tiv thaiv oxidation thiab xeb tom qab lub davhlau ya nyob twg plating puas lawm
Nyob rau hauv 10 lub sij hawm zoo ntawm plugging thiab unplugging, cov terminals cuam tshuam nrog ib leeg los ntawm kev cuam tshuam haum.Thaum muaj kev sib cuag siab, qhov sib txawv ntawm cov txiv neej thiab poj niam terminals yuav ua rau lub plating ntawm lub davhlau ya nyob twg nto los yog khawb me ntsis thaum lub sijhawm txav.Cov kab sib txawv ua rau tsis sib xws lossis txawm tias raug txheej txheej, ua rau muaj kev hloov pauv hauv cov qauv siv tshuab, khawb, nplaum, hnav cov khib nyiab, hloov khoom siv, thiab lwm yam, nrog rau kev tsim hluav taws xob.Qhov ntau zaus ntawm plugging thiab unplugging, qhov pom tseeb dua qhov kos cov cim ntawm qhov chaw ntawm lub davhlau ya nyob twg.Nyob rau hauv qhov kev txiav txim ntawm kev ua hauj lwm mus sij hawm ntev thiab ib puag ncig sab nraud, lub davhlau ya nyob twg yooj yim heev rau kev poob.Nws yog tsuas yog vim oxidative corrosion tshwm sim los ntawm kev sib txheeb me me ntawm qhov chaw sib cuag, feem ntau 10 ~ 100μm txheeb ze txav;Kev ua nruj ua tsiv yuav ua rau muaj teeb meem hnav ntawm qhov chaw sib cuag, me ntsis kev co yuav ua rau muaj kev sib txhuam corrosion, thermal shock thiab ib puag ncig cuam tshuam ua kom cov txheej txheem.
5 Kev xaus
Ntxiv txheej txheej plating rau lub davhlau ya nyob twg tuaj yeem tsis tsuas yog txo qhov corrosion ntawm cov khoom siv hauv lub davhlau ya nyob twg, tab sis kuj tseem txhim kho lub xeev ntawm kev siv dag zog.Txawm li cas los xij, txhawm rau txhawm rau ua kom muaj nuj nqi thiab kev lag luam, cov txheej txheej plating feem ntau yog hais txog cov kev siv hauv qab no: nws tuaj yeem tiv taus qhov kub thiab txias ntawm lub davhlau ya nyob twg;kev tiv thaiv ib puag ncig, tsis-corrosive;chemically ruaj khov;guaranteed davhlau ya nyob twg tiv tauj;txo kev sib txhuam thiab hnav rwb thaiv tsev;tus nqi qis.Raws li cov hluav taws xob ib puag ncig ntawm tag nrho lub tsheb yuav ntau thiab ntau nyuaj thiab lub zog tshiab era yog los, tsuas yog los ntawm tas li tshawb nrhiav cov cuab yeej tsim khoom ntawm cov khoom thiab cov khoom siv tau tuaj yeem ua kom nrawm nrawm ntawm cov haujlwm tshiab.
