Yuav ua li cas nrog rau tam sim no pogo pin connector cua sov?
Cov khoom siv hluav taws xob tam sim no muaj zog heev hauv kev siv hluav taws xob ua haujlwm thiab tseem muaj zog heev. Txawm li cas los xij, vim tias nws yog qhov loj tam sim no thiab tsim kom muaj cua sov ntau, nws yuav ua rau qee qhov tsis zoo hauv kev sib txuas. Txhua tus paub tias U=I^2RT. Qhov kev siv hluav taws xob no feem ntau yog hloov mus rau hauv kev faib hluav taws xob. Thaum tam sim no kuv tseem tsis tau hloov pauv, txo qhov kev tawm tsam yog tus yuam sij rau kev tsim. Lub sijhawm no, qhov kev tiv thaiv R=Rc tiv thaiv thiab +Rw (pin Jack siab tam sim no txuas tus kheej), ces yuav ua li cas txo qhov kev tawm tsam R?
1. Qhov roughness ntawm qhov sib cuag ntawm tus pin jack:
Cov tsos ntawm qhov zoo roughness, nws qhov chaw zoo yog qhov loj, qhov sib txuas ntawm kev sib cuag tsis tshua muaj, thiab nws cov hluav taws xob hluav taws xob muaj txiaj ntsig zoo, thiab qhov kev pheej hmoo ntawm kub plugging thiab unplugging yog qis dua.
2. Conductivity coefficient ntawm tus pin jack khoom:
Qhov tsis kam Rw ntawm cov khoom nws tus kheej yog nyob ntawm qhov coefficient, uas tuaj yeem txo qhov tsis kam thiab ib txwm txo lub zog tawm tswv yim.
Peb, txhim khu kev qha elastic kev twb kev txuas ntawm tus pin thiab socket khoom:
Vim nws lub neej expectancy, nws yog ib qho tsim nyog los xyuas kom meej tias nws tuaj yeem ruaj khov thaum siv ntau zaus. Qhov no muaj cov kev xav tau siab dua ntawm elasticity ntawm cov khoom thiab tuaj yeem ua kom ntseeg tau qhov kev sib cuag elastic.
Plaub, kev ua haujlwm thiab kev lag luam ntawm tus pin thiab qhov (socket) khoom:
Kev ua tau zoo ntawm tooj liab alloys sib txawv heev. Nyob rau tib lub sijhawm, nws yuav tsum sib haum nrog cov khoom hauv qab no. Tam sim no, tooj liab (tin phosphor bronze) yog siv dav hauv kev ua lag luam, uas muaj cov yam ntxwv hluav taws xob siab thiab muaj zog elasticity.
Yog li ntawd, thaum tsim cov khoom lag luam siab tam sim no, suav nrog kev txiav txim siab ua haujlwm tam sim no thiab kev ua haujlwm, thiab tom qab ntawd xaiv qhov tsim nyog ntawm cov hlau loj, qhov tseem ceeb yog kev xaiv cov khoom siv. Nyob rau hauv high-tam sim no connectors, tshwj xeeb tshaj yog thaum muaj ib tug nyob plugging thov, xyuas kom meej tias tus pin jacks yuav qhia nyob rau hauv parallel. Kub plugging muaj kev sib cuag tam sim lossis sib cais. Lub sijhawm no, qhov kev tawm tsam tiag tiag yog qhov kawg thiab lub sijhawm luv luv, tab sis nws tshwm sim. Lub tshav kub kuj tseem loj heev, uas yuav ua rau lub cuab yeej puas. Yog li ntawd, thaum tsim, xyuas kom meej tias lub kaum sab xis yog nyob rau hauv 3 degrees kom ntseeg tau tias kev ntxig thiab tshem tawm. High-tam sim no connectors muaj zog, tab sis lawv kuj muaj drawbacks. Cov teeb meem no yuav cuam tshuam qhov teeb meem kev sib txuas. Yog li ntawd, cov khoom ntawm tus pin jack yuav tsum tau ua kom zoo dua qub. Yog tias qhov saum toj no tuaj yeem ua tiav, cov khoom hluav taws xob ntuj kuj yuav hloov.
