Piv txwv li, ib ntu fais fab tuaj yeem siv 3.96mm ntsia hlau terminal blocks rau qhov sib txuas ntawm cov kab hluav taws xob, thaum cov teeb liab sab hauv siv 2.54mm solder terminal blocks rau kev sib txuas ntawm lub rooj tsavxwm mus rau hlau tas mus li. Tsuas yog qhov ceev faj xwb: xyuas kom koj cov txheej txheem sib dhos PCB ua raws li cov kauj ruam soldering ua ntej ntsia hlau terminal installation, vim tias qhov kub ntawm wave soldering (260 ° C) yuav ua rau lub tsev PA66 puas tsuaj yog tias lub terminal block yog wave-soldered tom qab ntsia hlau thiab hlau tawb tau teeb tsa.
Q: Lub neej kev pabcuam ntawm PCB mount terminal block yog dab tsi?
Nyob rau hauv cov xwm txheej hluav taws xob thiab ib puag ncig, peb cov thaiv davhlau ya nyob twg yog tsim los rau lub neej ua haujlwm tsawg kawg nkaus ntawm 15 xyoos ntawm 25 ° C ambient, raws li kev laus zuj zus raws li Arrhenius modeling nrog 10 ° C activation energy. Hauv kev xyaum, hom kev ua tsis tiav tseem ceeb uas peb pom hauv cov khoom xa rov qab tsis yog kev puas tsuaj ntawm cov khoom siv tab sis kev puas tsuaj los ntawm kev siv lub hau ntswj tsis raug - uas ua kom peb cov lus pom zoo siv cov ntsia hlau torque calibrated thaum lub sijhawm sib dhos.
Q: J-Guang puas muaj cov qhov ntev ntawm tus pin lossis cov plating tshwj xeeb?
Yog. Peb muaj peev xwm ua pwm thiab stamping hauv tsev uas tso cai rau peb hloov kho qhov ntev ntawm tus pin (tus qauv: 3.0mm–6.5mm), txoj kab uas hla ntawm tus pin, thiab plating tiav. Kub flash hla nickel muaj rau cov ntawv thov teeb liab qis qhov twg xav tau kev tiv tauj tsis pub dhau 2 milliohms. Qhov tsawg kawg nkaus kom muaj nuj nqis rau kev teeb tsa kev cai feem ntau yog 10,000 tus ncej, nrog rau lub sijhawm ua cov cuab yeej ntawm 2-3 lub lis piam.
Q: Tus nqi ntawm J-Guang piv rau Phoenix Contact lossis Weidmüller li cas?
Peb tus nqi feem ntau yog qis dua 40–60% piv rau Phoenix Contact lossis Weidmüller terminal blocks rau cov lus qhia sib piv, vim peb tsim khoom hauv Ningbo nrog kev txhaj tshuaj molding, stamping, thiab sib dhos ua ke es tsis yog xa cov txheej txheem no mus rau lwm lub tuam txhab. Txawm li cas los xij, peb xav kom pom tseeb: cov hom lag luam thoob ntiaj teb loj nqis peev ntau dua rau kev txhawb nqa kev tsim kho thiab kev khaws cia hauv zos. Peb txuas qhov sib txawv no los ntawm kev muab kev txhawb nqa kev tsim kho ncaj qha los ntawm WeChat thiab email nrog kev teb tib hnub ua haujlwm, ntxiv rau 3-7 hnub xa khoom sai sai rau North America thiab Europe los ntawm peb lub chaw Ningbo. Qhov kev xaiv zoo nyob ntawm seb koj qhov tseem ceeb yog tus nqi ib chav lossis kev txhawb nqa kev siv tshuab hauv zos.
Xaus Lus: Pib nrog Daim Ntawv Thov, Tsis yog Cov Lus Qhia Tshwj Xeeb
