Intshayelelo
Njengenxalenye ephambili yolawulo lwesekethe echanekileyo, umsantsa woqhagamshelwano yiparameter ebalulekileyo ekumiseleni ukusebenza kweswitshi encinci, echaphazela ngokuthe ngqo ubuntununtunu, ixesha lobomi kunye nokuziqhelanisa nokusingqongileyo. Ngenxa yokwanda kwemfuno ye-miniaturization kunye nokuthembeka okuphezulu kwi-automation yemizi-mveliso kunye ne-elektroniki yabathengi, uyilo kunye nokusetyenziswa komsantsa woqhagamshelwano kuye kwaba yinto ephambili kukhuphiswano lwetekhnoloji kushishino. Eli nqaku liza kudibanisa imigangatho yeshishini kunye namatyala amatsha ukuhlalutya iimpawu zobugcisa kunye nengqiqo yesicelo sesithuba soqhagamshelwano.
Iintlobo zeNgxelo yoQhagamshelwano kunye neempawu
Isithuba soqhagamshelwano lwee-micro switches sidla ngokwahlulahlulwa sibe ziindidi ezine, sigubungela uluhlu olupheleleyo lweemeko ukusuka kokuchaneka okuphezulu ukuya kokungcangcazela okuphezulu, kwaye ezi ntlobo zine ziyi-0.25mm class, 0.5mm class, 1.0mm class, kunye ne-1.8mm class, ngokulandelelana. Uvakalelo kunye nokumelana nokungcangcazela kwee-microswitches kunxulunyaniswa kakubi ne-contact pitch; i-0.25mm contact pitch inoyilo lwe-pitch encinci kakhulu kunye novakalelo oluphezulu (action force ≤ 0.1N), kodwa ukumelana kwayo nokungcangcazela kubuthathaka. Ngokuqhelekileyo isetyenziswa kwizixhobo zonyango (ezifana nezitshixo zezixhobo zotyando), i-precision sensor triggering, njl.njl., kufuneka ilawule ngokungqongqo i-current (≤ 0.1A) ukunciphisa ilahleko ye-contact. I-contact pitch yenqanaba le-0.55mm ngumgangatho oqhelekileyo kushishino ukulinganisela uvakalelo kunye nokuqina, kwaye ubomi bayo boomatshini bunokufikelela izihlandlo ezingaphezu kwezigidi ezi-5. Ngokuqhelekileyo isetyenziswa kwi-consumer electronics (amaqhosha emawusi), ulawulo lwezixhobo zasekhaya (ii-microwave door door switches) kunye nezinye iimeko ze-current eziphantsi ukuya kweziphakathi. Isithuba soqhagamshelwano esiyi-1.0mm someleza ukumelana nokungcangcazela (ukumelana nokutshayiswa ≥ 50G) kwaye sixhasa ukuqhekeka kwemisinga engaphezulu kwe-10A, kodwa ngesantya sokuphendula esicothayo kancinci. Ngokuqhelekileyo isetyenziswa kwiiswitshi zomda woomatshini bemizi-mveliso, ukhuseleko lokumisa ukungxamiseka kwenqwaba yezithuthi zamandla, njl. I-1.8mm contact pitch inoyilo olukhulu lwepitch, ukumelana kwe-arc kunyuke nge-50%, kulungele iimeko ezihlala zikhutshwa zomthwalo ophezulu. Ihlala isetyenziswa kwii-circuit breakers zenkqubo yamandla, oomatshini abanzima (ukufunyanwa komda we-crane) nakwezinye iindawo ezigqithisileyo.
Imingeni yoBugcisa kunye neMikhombandlela eNtsha
Nangona ukunciphisa i-contact pitch kunokuphucula uvakalelo, ijongene nemingeni emibini emikhulu: 1. Ukukhukuliseka kwe-Arc: Kwiimeko zamandla aphezulu, i-pitch encinci ithambekele ekufakweni kwe-oxidization ye-contacts ngenxa yokukhukuliseka kwe-arc, nto leyo efinyeza ubomi be-contact. Isisombululo siquka i-silver-nickel alloy contacts kunye noyilo lwe-ceramic interrupter, olunokwandisa ubomi bombane ukuya kuthi ga kumaxesha angaphezu kwama-500,000. 2. Ukunyamezelana nokusingqongileyo: ukungcangcazela kunye nomothuko kuthambekele ekuqaliseni okungeyonyani. Abavelisi balungiselele amandla entwasahlobo yokulayisha i-reed preload (umz., uthotho lwe-Honeywell's V15) kunye nesakhiwo sokudambisa ukuphucula ukumelana nokungcangcazela kwe-1.0mm pitch switches nge-40%.
Iindlela Zokusetyenziswa Kweshishini
Ukuphuculwa okukrelekrele: Ii-Micro switches ezineetships ezidityanisiweyo zokuva uxinzelelo (ezifana ne-Tesla Optimus robot fingertip module) zenza ulawulo oluhambelanayo ngokulungelelanisa iphimbo ngokujonga imeko yoqhagamshelwano ngexesha langempela.
Ukuveliswa okuluhlaza: I-EU RoHS 3.0 ikhuthaza ukwenziwa kwezinto zokunxibelelana ezingenayo i-cadmium zithandwa ngabantu abaninzi, kwaye iiswitshi zepitch ze-0.5mm zikhokela ekusebenziseni i-alloy yesilivere enobuhlobo nokusingqongileyo, zithathela ingqalelo ukusebenza kunye nokuthobela imithetho.
Isiphelo
Ukususela kwi-millimeter ngokuchanekileyo kwezixhobo zonyango ukuya kwi-walk pounds yemizi-mveliso enzima, inguqu kwezobuchwepheshe kwi-micro switch contact pitch ibonisa umnqweno wokugqibela weshishini lokuvelisa ukuchaneka nokuthembeka. Kwixesha elizayo, ngokudityaniswa kwesayensi yezinto eziphathekayo kunye ne-algorithms ezikrelekrele, le "parameter ye-microscopic" iya kuqhubeka nokunika amandla ukuphuculwa kwekhonkco lemizi-mveliso yehlabathi.
