Isingeniso
Njengengxenye eyinhloko yokulawula isekethe ngokunemba, igebe lokuxhumana liyipharamitha ebalulekile ekunqumeni ukusebenza kweswishi encane, ethinta ngqo ukuzwela, isikhathi sokuphila kanye nokuzivumelanisa nezimo zemvelo. Njengoba isidingo esikhulayo sokwenza izinto zibe zincane kanye nokuthembeka okuphezulu kokuzenzakalelayo kwezimboni kanye ne-electronics yabathengi, ukwakheka kanye nokusetshenziswa kwegebe lokuxhumana sekuyinto ebalulekile yokuncintisana kwezobuchwepheshe embonini. Lesi sihloko sizohlanganisa amazinga embonini kanye namacala amasha ukuhlaziya izici zobuchwepheshe kanye nomqondo wokusetshenziswa kwesikhala sokuxhumana.
Izinhlobo Zokuthintana Nezimpawu
Isikhala sokuxhumana sama-micro switch sivame ukuhlukaniswa ngezigaba ezine, sihlanganisa lonke uhla lwezimo kusukela ekuqondeni okuphezulu kuya ekumelaneni nokudlidliza okuphezulu, kanti izinhlobo ezine ziyi-0.25mm class, 0.5mm class, 1.0mm class, kanye ne-1.8mm class, ngokulandelana. Ukuzwela kanye nokumelana nokushaqeka kwama-microswitch kuhlobene kabi ne-contact pitch; i-contact pitch engu-0.25mm inomklamo we-pitch omncane kakhulu kanye nokuzwela okuphezulu (amandla esenzo ≤ 0.1N), kodwa ukumelana kwayo nokushaqeka kanye nokudlidliza kubuthakathaka. Ngokuvamile kusetshenziswa emishinini yezokwelapha (njengezihluthulelo zezinsimbi zokuhlinza), ukuqalisa inzwa yokunemba, njll., kudingeka kulawulwe ngokuqinile ugesi (≤ 0.1A) ukuze kuncishiswe ukulahleka kokuxhumana. I-contact pitch yezinga elingu-0.55mm iyindinganiso evamile embonini yokulinganisela ukuzwela nokuqina, futhi impilo yayo yemishini ingafinyelela izikhathi ezingaphezu kwezigidi ezi-5. Ngokuvamile isetshenziswa kuma-electronics asetshenziswa ngabathengi (izinkinobho zegundane), ukulawula izinto zasekhaya (izinkinobho zomnyango we-microwave oven) kanye nezinye izimo zamandla aphansi kuya kwaphakathi. Isikhala sokuxhumana esingu-1.0mm siqinisa ukumelana nokudlidliza (ukumelana nokushaqeka ≥ 50G) futhi sisekela ukuphuka kwemisinga engaphezu kuka-10A, kodwa ngesivinini sokuphendula esihamba kancane. Ngokuvamile kusetshenziswa ekushintsheni komkhawulo wemishini yezimboni, ukuvikelwa kokuma okuphuthumayo kwenqwaba yokushaja kwemoto entsha, njll. Iphimbo lokuxhumana elingu-1.8mm linomklamo omkhulu wephimbo, ukumelana kwe-arc kukhuphuke ngo-50%, kufaneleka ezimweni ezivame ukwenzeka zomthwalo ophezulu. Ngokuvamile kusetshenziswa kuma-circuit breakers esistimu yamandla, imishini esindayo (ukutholwa komkhawulo we-crane) nakwezinye izindawo ezibucayi.
Izinselele Zobuchwepheshe Neziqondiso Ezintsha
Nakuba ukwehla kwephimbo lokuxhumana kungathuthukisa ukuzwela, kubhekene nezinselele ezimbili ezinkulu: 1. Ukuguguleka kwe-Arc: Ezimweni zamandla aphezulu, iphimbo elincane lithambekele ekufakweni kwe-oxidation koxhumana nabo ngenxa yokuguguleka kwe-arc, okunciphisa impilo yoxhumana nabo. Isixazululo sihlanganisa oxhumana nabo be-silver-nickel alloy kanye nomklamo we-ceramic interrupter, okungandisa impilo kagesi ibe ngaphezu kwezikhathi ezingu-500,000. 2. Ukubekezelelana kwemvelo: ukudlidliza kanye nokushaqeka kuthambekele ekuqhumeni okungamanga. Abakhiqizi bathuthukise amandla entwasahlobo okulayisha kusengaphambili komhlanga (isb., uchungechunge lwe-V15 lukaHoneywell) kanye nesakhiwo sokudambisa ukuze kuthuthukiswe ukumelana kokudlidliza kwama-switch ephimbo angu-1.0mm ngo-40%.
Amathrendi Okusetshenziswa Kwemboni
Ukuthuthukiswa okuhlakaniphile: Ama-Micro switch anama-chip ahlanganisiwe okuzwa ingcindezi (njenge-module ye-Tesla Optimus robot fingertip) alawula ukuguquguquka ngokushintsha iphimbo ngokuqhubekayo ngokuqapha isimo sokuxhumana ngesikhathi sangempela.
Ukukhiqiza okuluhlaza: I-EU RoHS 3.0 ikhuthaza ukuthandwa kwezinto zokuxhumana ezingenayo i-cadmium, kanti izinkinobho zephimbo ezingu-0.5mm zihola ekusebenziseni i-alloy yesiliva enobungani nemvelo, kucatshangelwa kokubili ukusebenza kanye nokuhambisana.
Isiphetho
Kusukela ekuqondeni kwe-millimeter kwemishini yezokwelapha kuya kumakhilogremu ayinkulungwane emboni esindayo, ukuvela kobuchwepheshe be-micro switch contact pitch kubonisa ukuphishekela kokugcina kwemboni yokukhiqiza ukunemba nokuthembeka. Esikhathini esizayo, ngokuhlanganiswa kwesayensi yezinto ezibonakalayo kanye nama-algorithms ahlakaniphile, le "parameter ye-microscopic" izoqhubeka nokunika amandla ukuthuthukiswa kochungechunge lwezimboni zomhlaba wonke.
