Cov khoom siv thiab cov yam ntxwv ntawm pogo pin jack
Lub qhov (socket) feem ntau yog tooj dag, tooj liab, lossis tooj liab, thiab sab nrauv yog tinned, npib tsib xee-plated, lossis kub-plated. Lawv txhua tus muaj cov yam ntxwv hauv qab no:
Ua ntej, cov yam ntxwv ntawm tooj dag: Peb cov ntaub ntawv xaiv yog H59, H62 thiab H65, feem ntau yog alloys muaj li ntawm tooj liab thiab zinc. H59 yog qhov pheej yig tshaj tooj dag. Nws muaj lub zog siab, hardness, thiab zoo plasticity, thiab nws tseem tuaj yeem tiv taus kev ua haujlwm zoo nyob rau hauv cov xwm txheej kub. Thaum corrosion kuj zoo li qub, lwm yam khoom zoo ib yam li H62; H65 muaj cov khoom siv zoo, Cov yas zoo hauv lub xeev kub, zoo plasticity nyob rau hauv lub xeev txias, zoo machinability, yooj yim rau brazing thiab vuam, corrosion kuj, tab sis prone rau corrosion thiab cracking, thiab nws cov nqi yog tsawg. Cov khoom ntawm peb cov ntaub ntawv no kuj zoo ib yam thiab Nws kuj yog siv dav.
Thib ob, bronze yam ntxwv: bronze feem ntau muab faib ua peb yam khoom nrog tooj dag: phosphor bronze (c54400), tin bronze (Qsh4-3, Qsh6.5-0.1), beryllium tooj liab (c5191, c17300). Tin phosphor bronze muaj ntau dua corrosion kuj, hnav tsis kam, thiab yuav tsis tsim sparks thaum xuas nrig ntaus; Qhov loj feem ntawm beryllium nyob rau hauv beryllium tooj liab yog 1.7-2.5%, thiab beryllium bronze muaj peev xwm muaj zog heev thiab hardness tom qab quenching thiab laus. , Nrog cov khoom siv tsis siv neeg ua rau melting, extrusion, calendering, thiab stretching, xws li muaj zog convection ci annealing rauv, tau dav siv los ntawm domestic high-tech, tub rog, txawv teb chaws thiab ntiav lag luam.
Thib peb, cov ntsiab lus tooj liab ntawm tooj liab liab (T2) yog siab li 99.99%. Nws muaj cov khoom siv hluav taws xob zoo thiab thermal conductivity thiab muaj qhov tshwj xeeb zoo plasticity. Nws yog ib qho yooj yim rau siv nyob rau hauv kub nias thiab txias nias. Nws yog lub roj teeb loj hauv lub zog tshiab.
Cov hluav taws xob conductivity ntawm peb cov khoom siv tooj liab tau hais los saum no yog txhua yam zoo heev, thiab lawv tau siv dav hauv kev ua lag luam tam sim no.
