Dab tsi yog Cov Ntsiab Lus Tseem Ceeb Ntawm Cov Khoom Muag Ntawm Cov Header Thiab Cov Poj Niam Txuas Txuas
Tso lus
Pin headers thiab poj niam feem ntau yog siv connector plug-ins nyob rau hauv cov khoom siv hluav taws xob. Thaum lub sij hawm ua, kev tsim khoom lossis kev siv, tus pin headers thiab poj niam connectors feem ntau cuam tshuam los ntawm ntau yam, xws li kev ua thiab kev tsim khoom. Hlau kos duab, thermal deformation quab yuam thaum SMT txheej txheem, thiab lwm yam.
Txuas
Tsis tas li ntawd, qhov ntsaws lossis kev vibration ntawm tus pin header thiab poj niam connector khoom thaum siv yuav tsim cov nqi sib txawv, uas yuav ua rau lub davhlau ya nyob twg (tus neeg xyuas pib) sib txawv ntawm txoj haujlwm ua haujlwm thiab ua rau cov khoom' ua haujlwm ua tsis tiav.
Cov ntsiab lus tseem ceeb ntawm cov khoom kuaj ntawm header thiab poj niam connector:
Cov khoom kuaj yog tag nrho tus pin header thiab poj niam connector khoom, tshwj xeeb tshaj yog cov plug contact point. Qhov kev xeem axis yog qhov kev siv ib txwm siv ntawm header thiab poj niam connector khoom, xws li cov kev taw qhia zoo thiab tsis zoo ntawm lub davhlau ya nyob twg los ua ke.
Tshwj tsis yog tias koj yuav tsum tau qhia tshwj xeeb header thiab poj niam connector khoom, lub dav dav ceev yog 25.4mm / feeb. Nyob rau hauv tus txheej txheem ntawm kev kuaj kev puas tsuaj, tus qauv yuav tsum tau feem ntau teem rau qhov tsawg kawg nkaus tus nqi (4.9NMin.).
Lub ntsiab lus ntawm cov khoom txuas txuas lub davhlau ya nyob twg tuav lub zog yog los xyuas kom meej tias lub davhlau ya nyob twg (tus neeg xyuas pib) yog tsau rau hauv cov yas, thiab lub davhlau ya nyob twg hauv cov yas yog nyob rau hauv kev ua thiab kev tsim khoom, xws li vuam lossis rub thaum tuav cov khoom, txheej txheem SMT thiab siv cov txheej txheem, xws li Txiv neej thiab poj niam mating txheej txheem.
Kev vibration thiab cuam tshuam ntawm header thiab poj niam connector khoom thaum lub sij hawm ua thiab tsim cov txheej txheem yuav cuam tshuam los ntawm sab nraud quab yuam, yog li lub zog tuav ntawm lub davhlau ya nyob twg thiab cov yas yuav tsum txaus, txwv tsis pub lub davhlau ya nyob twg yuav cuam tshuam los ntawm lwm yam, ua rau PIN degradation, ua rau muaj kev cuam tshuam kev sib txuas lossis kev sib txuas ua haujlwm tsis ua haujlwm.
