Intshayelelo
Kwizixhobo ze-elektroniki kunye neenkqubo zokuzenzekelayo, ii-micro switches, ezinobukhulu bazo obuncinci kunye nokusebenza okugqwesileyo, ziye zaba zizinto eziphambili zokufezekisa ulawulo oluchanekileyo. Olu hlobo lwe-switch lufezekisa ulawulo oluthembekileyo kakhulu lwesekethe ngaphakathi kwendawo encinci ngoyilo olunobuchule loomatshini kunye nophuhliso lwezinto ezintsha. Ingundoqo yalo ikwiindlela ezine zobuchwepheshe: indlela yokusebenza ngokukhawuleza, ukulungiswa kwesithuba soqhagamshelwano, ukuphuculwa kokuqina, kunye nolawulo lwe-arc. Ukusuka kumaqhosha emawusi ukuya kwizixhobo ze-aerospace, ubukho bee-microswitches bukhona kuyo yonke indawo. Ukungabi nakutshintshwa kwazo kuvela ekusebenziseni ngokuchanekileyo imithetho yendalo kunye nokuphishekela ngokupheleleyo imveliso yemizi-mveliso.
Iindlela eziphambili kunye neenzuzo zobuchwepheshe
Indlela esebenza ngokukhawuleza
Isiseko se-microswitch sikwindlela yayo yokusebenza ngokukhawuleza, eguqula amandla angaphandle abe ngamandla anamandla e-elastic e-reed ngokusebenzisa izinto zokudlulisa ezifana nee-levers kunye nee-rollers. Xa amandla angaphandle efikelela kwixabiso elibalulekileyo, i-reed ikhupha amandla ngoko nangoko, iqhubela oonxibelelwano ukuba bagqibezele ukutshintshwa kokucima ngesantya se-millisecond. Le nkqubo ayixhomekekanga kwisantya samandla angaphandle. Inzuzo yendlela yokusebenza ngokukhawuleza ikwindlela yokunciphisa ubude be-arc. Xa oonxibelelwano bahlukana ngokukhawuleza, i-arc ayikayikhi itshaneli yeplasma ezinzileyo, ngaloo ndlela inciphisa umngcipheko wokususwa koqhagamshelwano. Idatha yovavanyo ibonisa ukuba indlela yokusebenza ngokukhawuleza inokunciphisa ubude be-arc ukusuka kumakhulu aliqela ee-milliseconds zotshintsho zendabuko ukuya kwi-5-15 milliseconds, ngokufanelekileyo yandisa ubomi benkonzo.
Uyilo lwezinto ezintsha
Ukukhethwa kwezinto ezidityanisiweyo yeyona nto iphambili ekuqineni. Ii-alloy zesilivere zisebenza kakuhle kakhulu kwizicelo zamandla aphezulu ngenxa yokuqhuba kwazo umbane okuphezulu kunye neempawu zokuzicoca, kwaye iileya zazo ze-oxide zinokususwa yimpembelelo yamandla. Ii-alloy ze-titanium alloy zaziwa ngobunzima bazo obulula, amandla aphezulu kunye nokumelana nokugqwala. Iiswitshi zokuchonga ezimbini ze-ALPS zisebenzisa ii-alloy ze-titanium alloy, ezinobomi boomatshini obufikelela kwi-10 yezigidi, obungaphezulu kwesihlanu kunee-alloy zendabuko ze-copper alloy. Ii-microswitches kwintsimi yeenqwelo-moya zikwasebenzisa ii-alloy zesilivere ezifakwe igolide, ezifana ne-hatch switch yeShenzhou-19, esenokugcina ukusebenza okungenaziphene kangangeminyaka engama-20 phantsi kobushushu obuphezulu obuqala kwi--80 ℃ ukuya kwi-260 ℃, kwaye impazamo yokuvumelanisa unxibelelwano ingaphantsi kwemizuzwana eyi-0.001.
Intetho yoqhagamshelwano
Isithuba soqhagamshelwano se-microswitch sidla ngokuba phakathi kwe-0.25 kunye ne-1.8 yeemilimitha. Esi sithuba sincinci sichaphazela ngokuthe ngqo ubuntununtunu kunye nokuthembeka. Thatha isithuba se-0.5 yeemilimitha njengomzekelo. Ukuhamba kwayo ngentshukumo kufuna kuphela iimilimitha ze-0.2 ukuze kuqaliswe, kwaye ukusebenza kokulwa nokungcangcazela kufezekiswa ngokuphucula izixhobo zoqhagamshelwano kunye nesakhiwo.
Ulawulo lwe-arc
Ukuze kuthintelwe i-arc, i-microswitch isebenzisa ubuchwepheshe obuninzi:
Indlela esebenza ngokukhawuleza: Nciphisa ixesha lokwahlulwa koqhagamshelwano kwaye unciphise ukuqokelelwa kwamandla e-arc
Ulwakhiwo lokucima i-arc: I-arc ipholiswa ngokukhawuleza ngokusebenzisa igumbi lokucima i-arc yeseramikhi okanye iteknoloji yokuvuthela i-arc yegesi.
Ukulungiswa kwezinto: Umphunga wesinyithi oveliswa ziingcingo zesilivere phantsi kombane ophezulu unokusasaza ngokukhawuleza, uphephe ukubakho okuqhubekayo kweplasma.
Uthotho lweHoneywell V15W2 luphumelele isiqinisekiso se-IEC Ex kwaye lufanelekile kwiindawo ezinokuqhuma. Ulwakhiwo lwayo lokutywina kunye noyilo lokucima i-arc lunokufikelela ekungavuzini i-arc kwi-current ye-10A.
Ukusetyenziswa kweshishini kunye nokungathathelwa indawo
Izixhobo ze-elektroniki zabathengi
Izixhobo ezifana namaqhosha eempuku, ii-gamepad, kunye neekhibhodi zelaptop zixhomekeke kwii-microswitches ukuze zifumane iimpendulo ezikhawulezayo. Umzekelo, ixesha lokuphila kwe-microswitch ye-e-sports mouse kufuneka lifikelele ngaphezu kwezigidi ezingama-50. Nangona kunjalo, uthotho lweLogitech G lusebenzisa imodeli ye-Omron D2FC-F-7N (20M). Ngokuphucula uxinzelelo loqhagamshelwano kunye ne-stroke, ifikelela kwi-trigger delayers ye-0.1 milliseconds.
Imizi-mveliso kunye neeMoto
Kwi-automation yemizi-mveliso, ii-microswitches zisetyenziselwa ukubeka amalungu eengalo zoomatshini, ukunciphisa iibhanti zokuhambisa kunye nokulawula iingcango zokhuseleko. Kwicandelo leemoto, isetyenziswa kakhulu ekuqaliseni ii-airbag, ukulungisa izihlalo kunye nokubona ucango. Umzekelo, i-microswitch yocango yeTesla Model 3 isebenzisa uyilo olungangeni manzi kwaye ingasebenza ngokuzinzileyo kwindawo ephakathi kwe--40 ℃ ukuya kwi-85℃.
Ukhathalelo lwezeMpilo kunye neenqwelo-moya
Izixhobo zonyango ezifana nee-ventilators kunye neemonitha zixhomekeke kwii-microswitches ukuze zifezekise ukulungiswa kweparameter kunye ne-alamu yempazamo. Ukusetyenziswa kwicandelo leenqwelo-moya kufuna okungakumbi. I-microswitch yomnyango wekhabhathi yenqwelo-moya yaseShenzhou kufuneka iphumelele uvavanyo lokungcangcazela, ukukhwankqiswa kunye nokutshizwa ngetyuwa. I-casing yayo yesinyithi yonke kunye noyilo olumelana nobushushu luqinisekisa ukhuseleko olupheleleyo kwindawo.
Isiphelo
"Amandla aphezulu" ee-microswitches avela ekudityanisweni okunzulu kwemigaqo yoomatshini, isayensi yezinto kunye neenkqubo zokuvelisa. Ukukhululwa kwamandla ngokukhawuleza kwendlela esebenza ngokukhawuleza, ukuchaneka kwenqanaba le-micron kwesithuba soqhagamshelwano, impumelelo ekuqineni kwezinto ze-titanium alloy, kunye nokukhuselwa okuninzi kolawulo lwe-arc kwenza ukuba kungabi nakutshintshwa kwicandelo lolawulo oluchanekileyo. Ngokuhambela phambili kobukrelekrele kunye nokuzenzela, ii-microswitches ziyaphuhla zijolise kwi-miniaturization, ukuthembeka okuphezulu kunye nokusebenza okuninzi. Kwixesha elizayo, ziya kudlala indima enkulu kwiindawo ezifana nezithuthi zamandla amatsha, iirobhothi zoshishino kunye ne-aerospace. Eli candelo "lincinci, lamandla amakhulu" liqhubeka liqhuba uphando lwabantu ngemida yokuchaneka kolawulo.
