Hauv ntiaj teb cov khoom siv hluav taws xob,laub khawm keyboardsyog cov khoom siv tseem ceeb uas pab txhawb cov neeg siv kev sib cuam tshuam nrog ntau lub tshuab hluav taws xob. Kev hloov pauv yog tsim los muab txoj hauv kev yooj yim thiab siv tau los tswj cov circuits, ua rau nws yog ib qho tseem ceeb hauv ntau daim ntawv thov xws li cov khoom siv hauv tsev mus rau kev siv tshuab. Push khawm keyboards yog qhov yooj yim rau kev khiav lag luam, tso cai rau cov neeg siv txuas lossis txiav lub voj voog nrog lub laub khawm, kom ntseeg tau yooj yim ntawm kev siv thiab kev ua haujlwm zoo.
Tsim kom tau raws li cov qauv hluav taws xob nruj, lublaub khawm hloovyog ntsuas ntawm 10A (250VAC). Qhov ntsuas tam sim no qhia tau tias nws tuaj yeem tiv taus hluav taws xob siab thiab tsim nyog rau ntau yam kev siv. Qhov hloov pauv qhov kev tiv thaiv yog khaws cia ntawm ≤50mΩ (tus nqi pib), kom ntseeg tau tias lub zog poob qis thaum ua haujlwm. Nws cov rwb thaiv tsev tiv thaiv kuj tseem ceeb, nrog qhov tsawg kawg ntawm ≥100MΩ ntawm 500VDC, kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha txawm nyob rau hauv ib puag ncig hnyav. Cov kev qhia tshwj xeeb no qhia txog kev ntseeg tau thiab ua haujlwm ntev ntawm lub laub khawm hloov, ua rau nws yog thawj qhov kev xaiv rau engineers thiab designers.
Kev nyab xeeb ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb tshaj plaws thiab lub laub khawm hloov xa mus rau pem hauv ntej. Tsim los tiv thaiv cov hluav taws xob hluav taws xob siab, qhov hloov pauv tau ntsuas ntawm 500V / 0.5mA / 60S ntawm cov tsis txuas txuas thiab 1500V / 0.5mA / 60S ntawm terminals thiab hlau ncej. Cov yam ntxwv no ua kom lub qhov hloov pauv ua haujlwm zoo nyob rau hauv ntau yam kev mob, ua rau cov neeg siv kev thaj yeeb nyab xeeb. Lub laub khawm hloov tau tsim kom kawg, nrog lub neej hluav taws xob ntawm ≥50,000 cycles thiab lub neej txhua yam ntawm ≥100,000 cycles.
Covlaub khawm hloovkuj ua tau zoo nyob rau hauv kev khiav hauj lwm tej yam kev mob, nrog ib tug kub ntawm 0 mus rau 125 ° C, ua rau nws ua hauj lwm zoo nyob rau hauv ntau yam ntawm ib puag ncig. Lub tshuab hluav taws xob tuaj yeem tiv taus 15 kev ua haujlwm hluav taws xob thiab 60 lub tshuab ua haujlwm, ua kom pom tias nws muaj peev xwm siv tau ntau yam. Lub laub khawm hloov yog tsim los tiv thaiv kev poob siab thiab kev vibration, nrog kev vibration zaus ntawm 10-55HZ, amplitude ntawm 1.5mm, thiab lub sijhawm ntev ntawm ib teev nyob rau hauv peb cov lus qhia.Qhov toughness no ua rau nws zoo tagnrho rau siv nyob rau hauv industrial cheeb tsam uas cov khoom yuav raug mob hnyav.
Lub laub khawm hloov ua tau raws li ntau daim ntawv pov thawj kev nyab xeeb, suav nrog UL, CSA, TUV, CQC thiab CE, kom ntseeg tau tias ua raws li cov qauv kev nyab xeeb thoob ntiaj teb. Qhov kev hloov pauv qhov kev sib tw kuj tseem muaj kev txhawj xeeb, xav tau ntau dua 80% ntawm qhov chaw raus dej kom raug them los ntawm cov khoom siv thiab ua raws li cov txheej txheem tshwj xeeb ntawm qhov kub thiab txias thiab lub sijhawm immersion. Cov yam ntxwv no, ua ke nrog kev hloov pauv qhov kev tsim qauv rugged thiab txhim khu kev qha, ua rau lub laub khawm hloov ib qho tseem ceeb hauv cov tshuab hluav taws xob niaj hnub no.
