[Abstract] Kweli nqanaba, ukuze kuqinisekiswe ukudibanisa kunye nokuhlanganiswa okuphezulu kwemisebenzi yombane wesithuthi, kunye nokuhlangabezana nophuhliso lwesakhiwo esitsha sombane esikrelekrele, ujongano olukhethiweyo lwesinxibelelanisi lunomgangatho ophezulu wokudityaniswa (kungekhona nje ukuhambisa okuphezulu. unikezelo lwangoku kunye nombane ophezulu, kodwa kunye nokuhambisa i-voltage ephantsi kunye ne-low-current signal analog), khetha amanqanaba ahlukeneyo ezakhiwo zokudityaniswa kwemisebenzi eyahlukeneyo kunye nezikhundla ezahlukeneyo ukuqinisekisa ukuba ubomi benkonzo yesidibaniso akufanele bube buphantsi kunobomi benkonzo. yezithuthi eziqhelekileyo, ngaphakathi koluhlu lwempazamo oluvumelekileyo Ukuhanjiswa okuzinzile konikezelo lwamandla kunye neempawu zolawulo kufuneka kuqinisekiswe;izixhumi zidityaniswe ngee-terminals, kwaye ii-terminals zamadoda nabasetyhini zenziwe ngezinto zokuqhuba isinyithi.Umgangatho woxhumo lwe-terminal luchaphazela ngokuthe ngqo ukuthembeka kwemisebenzi yombane yesithuthi.
1. Intshayelelo
Iitheminali zokubopha iintambo zothumelo lwangoku kwiintambo zokubopha iintambo zesithuthi ngokubanzi zigximfizwe kwi-alloys yobhedu ekumgangatho ophezulu.Enye indawo yeetheminali kufuneka ibotshelelwe kwiqokobhe leplastiki, kwaye enye idityaniswe ngombane kwiitheminali zokukhwelana.I-alloy yobhedu Nangona ineempawu ezilungileyo zoomatshini, ukusebenza kwayo ekuqhubeni kombane ayonelisiyo; Ngokubanzi, izinto ezinokuhanjiswa kombane zinomgangatho oqhelekileyo wezakhiwo, njengetoti, igolide, isilivere, njalo njalo.Ke ngoko, i-plating iyimfuneko kakhulu ukubonelela iitheminali nge-conductivity eyamkelekileyo yombane kunye neempawu zoomatshini ngaxeshanye.
Iintlobo ezi-2 zokuPlayitha
Ngenxa yemisebenzi eyahlukeneyo yeetheminali kunye neendawo ezahlukeneyo zokusetyenziswa (ubushushu obuphezulu, umjikelo we-thermal, ukufuma, ukothuka, ukungcangcazela, uthuli, njl.njl.), i-plating ye-terminal ekhethiweyo nayo yahluka, ngokuqhelekileyo ngobushushu obuqhubekayo, ubukhulu be-plating, iindleko, ukubhangqa Umaleko ofanelekileyo wokucwenga wetheminali yokukhwelana kukukhetha iitheminali ezinomaleko ohlukeneyo wokucwenga ukuhlangabezana nokuzinza komsebenzi wombane.
3 Ukuthelekiswa kweeCoatings
3.1 Iitheminali ezinetoti
Ukufakwa kwenkcenkce ngenkcenkce ngokuqhelekileyo kunozinzo olulungileyo lokusingqongileyo kunye neendleko eziphantsi, ngoko ke kusetyenziswa kakhulu, kwaye zininzi iileya zenkcenkce ezisetyenziswa kwimiba eyahlukeneyo, njengetoti emnyama, itoti eqaqambileyo, kunye netoti yediphu eshushu.Xa kuthelekiswa nezinye iingubo zokugquma, ukuxhathisa ukunxiba akubi, ngaphantsi kwe-10 imijikelo yokukhwelana, kwaye ukusebenza koqhagamshelwano kuya kuncipha kunye nexesha kunye nobushushu, kwaye ngokuqhelekileyo kusetyenziswa kwiimeko eziphantsi kwe-125 ° C.Xa uyila ii-terminals ze-tin-plated, amandla oqhagamshelwano oluphezulu kunye nokufuduka okuncinci kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuzinza koqhagamshelwano.
3.2 Iitheminali ezinePlati zeSilivere
I-Silver plating ngokubanzi inomsebenzi omhle woqhagamshelwano, ingasetyenziswa ngokuqhubekayo kwi-150 ° C, ixabiso libiza kakhulu, kulula ukugqwala emoyeni xa kukho isulfure kunye neklorini, inzima kune-tin plating, kwaye ukumelana kwayo kuncinci. iphezulu okanye ilingana ne-tin, into enokwenzeka ye-electromigration ikhokelela ngokulula kwimingcipheko enokubakho kwikhonkco.
3.3 Iitheminali ezifakwe ngegolide
Iitheminali ezifakwe ngegolide zinonxibelelwano oluhle kunye nokuzinza kokusingqongileyo, ubushushu obuqhubekayo bunokugqithisa i-125 ℃, kwaye inokumelana nokukhuhlana okuhle kakhulu.Igolide elukhuni ilukhuni kunetoti nesilivere, kwaye inokumelana nokukhuhlana okugqwesileyo, kodwa ixabiso layo liphezulu, kwaye ayizizo zonke i-terminal ezifuna ukubekwa kwegolide.Xa amandla oqhagamshelwano esezantsi kwaye umaleko wokutyabeka wenkcenkce unxibile, endaweni yoko kunokusetyenziswa ukucakwa kwegolide.Indawo yokukhwelela.
4 Ukubaluleka kweSicelo sokuPlayizwa kweSitena
Ayinakunciphisa kuphela i-corrosion ye-terminal material surface, kodwa iphinde iphucule imeko yamandla okufaka.
4.1 Ukunciphisa ukungqubana kunye nokunciphisa amandla okufaka
Izinto eziphambili ezichaphazela i-coefficient of friction phakathi kwe-terminals zibandakanya: izinto eziphathekayo, uburhabaxa bomhlaba, kunye nokuphathwa kwendawo.Xa i-terminal material ilungisiwe, i-coefficient ye-friction phakathi kwee-terminals igxininisekile, kwaye i-roughness ehambelana nayo inkulu.Xa umphezulu we-terminal uphathwa nge-coefficient, i-coefficient ye-coefficient, i-coefficient ye-coefficient, i-coefficient ye-coefficient, kunye ne-coefficient ye-coefficient.
4.2 Thintela i-oxidation kunye nomhlwa emva kokuba i-terminal plating yonakalisiwe
Ngaphakathi kwamaxesha ali-10 asebenzayo okuplaga kunye nokukhupha iplagi, iitheminali zinxibelelana enye kwenye ngokuphazamiseka kokulungelelana.Xa kukho uxinzelelo loqhagamshelwano, ukufuduswa okuzalanayo phakathi kweetheminali zamadoda nabasetyhini kuya konakalisa iplating kumphezulu wetheminali okanye kuyikrwele kancinci ngexesha lentshukumo.Umkhondo ukhokelela kubunzima obungalinganiyo okanye ukuvezwa kwengubo, okukhokelela kutshintsho kwisakhiwo soomatshini, imikrwelo, ukuncamathelisa, ukunxiba inkunkuma, ukuhanjiswa kwezinto, njl., kunye nokuveliswa kobushushu. Amaxesha amaninzi okuplaga kunye nokukhupha iplagi, kokukhona kucaca ngakumbi amanqaku okukrwela kumphezulu wetheminali.Ngaphantsi kwesenzo somsebenzi wexesha elide kunye nokusingqongileyo kwangaphandle, i-terminal ilula kakhulu ukungaphumeleli.Ikakhulu ngenxa ye-oxidative corrosion ebangelwa yintshukumo encinci yesalamane yendawo yoqhagamshelwano, ngokuqhelekileyo i-10 ~ 100μm intshukumo ehambelanayo;intshukumo enobundlobongela inokubangela ukunxitywa okuyingozi phakathi kweendawo zokudibana, ukungcangcazela okuncinci kunokubangela ukuthotywa kwe-friction, ukothuka kwe-thermal kunye neempembelelo zokusingqongileyo zikhawulezisa inkqubo.
5 Isiphelo
Ukongeza i-plating layer kwi-terminal ayikwazi ukunciphisa kuphela i-corrosion kumphezulu we-terminal material, kodwa nokuphucula imeko yokufakwa kwamandla.Nangona kunjalo, ukwenzela ukwandisa umsebenzi kunye noqoqosho, i-plating layer ibhekisela ikakhulu kwiimeko ezilandelayo zokusetyenziswa: inokumelana neemeko zokushisa zangempela ze-terminal;ukukhuselwa kokusingqongileyo , ukungonakalisi;uzinzile ngokwekhemikhali;uqhagamshelwano lwe-terminal oluqinisekisiweyo;ukukhuhlana okuncitshisiweyo kunye nokufakwa kwe-insulation;ixabiso eliphantsi.Njengoko indawo yombane yesithuthi sonke iba nzima ngakumbi kwaye ixesha elitsha lamandla liza, kuphela ngokuphonononga rhoqo iteknoloji yokuvelisa iinxalenye kunye namacandelo okunokuthi ukuphindaphinda ngokukhawuleza kwemisebenzi emitsha kuhlangatyezwane nayo.
