Lub luag haujlwm ntawm pogo pin connectors hauv kev lag luam hluav taws xob
Lub connector zoo li lub functional interface ntawm qhov kev pab cuam. Yog tias qhov kev npaj tsim nyog, kev tiv thaiv cov khoom lag luam yav tom ntej, kev txhim kho, thiab kev hloov pauv yuav yog ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog kom cov khoom muaj peev xwm tswj tau qhov tseem ceeb ntev; Thaum kawg, cov khoom poob nws qhov kev sib tw, thiab qhov tseem ceeb ntawm cov khoom sib txuas yog qhov tseeb ntawm nws tus kheej.
Pogo pin Connectors, uas feem ntau hu ua connectors los ntawm engineers, yog siv los txuas ob lub rooj tsav xwm hluav taws xob los yog cov khoom siv hluav taws xob los ua kom tiav kev xa hluav taws xob lossis cov teeb liab. Los ntawm kev sib txuas, lub voj voog tuaj yeem hloov kho, cov txheej txheem kev teeb tsa ntawm cov khoom siv hluav taws xob tuaj yeem ua kom yooj yim, thiab cov khoom tuaj yeem tiv thaiv tau yooj yim thiab kho dua tshiab.
Pogo pin Connector
Rau modular circuits, xaiv cov connectors plays lub luag hauj lwm tseem ceeb. Yog li thaum xaiv connectors, los ntawm cov ces kaum twg peb yuav tsum xav txog cov connectors haum rau kev siv kho vajtse?
1. Pins thiab qhov sib txawv
Tus naj npawb ntawm tus pins thiab qhov sib nrug ntawm tus pins yog lub hauv paus rau kev xaiv cov khoom sib txuas. Tus naj npawb ntawm pins xaiv rau lub connector yog nyob ntawm tus naj npawb ntawm cov teeb liab uas yuav tsum tau txuas. Rau qee qhov sib txuas sib txuas, tus naj npawb ntawm cov pins hauv thaj chaw headers raws li qhia hauv daim duab hauv qab no yuav tsum tsis txhob ntau dhau. Vim hais tias nyob rau hauv cov txheej txheem soldering ntawm lub tshuab muab tso rau, vim yog kub, connector yas yuav rhuab thiab deformed, thiab nyob rau hauv nruab nrab ib feem yuav bulge, uas ua rau tsis muaj tseeb soldering ntawm cov pins. Peb P800Flash programmer siv tus pin header thiab poj niam header los ua lub rooj sib tham-rau-board kev sib txuas nyob rau theem pib ntawm kev loj hlob. Yog li ntawd, tus pins ntawm tus qauv tus pin header tau soldered nyob rau hauv ib cheeb tsam loj. Tom qab hloov mus rau 2 tus pin headers nrog halved pins, tsis muaj cuav soldering.
Niaj hnub no, cov khoom siv hluav taws xob tau tsim los ntawm kev ua haujlwm me me thiab qhov tseeb, thiab tus pin pitch ntawm lub connector kuj tau hloov ntawm 2.54mm mus rau 1.27mm thiab tom qab ntawd mus rau 0.5mm. Qhov me me ntawm cov hlau lead suab, qhov siab dua qhov yuav tsum tau ua rau cov txheej txheem ntau lawm. Qhov sib nrug ntawm cov hlau lead yuav tsum tau txiav txim los ntawm lub tuam txhab' qib kev tsim khoom siv tshuab. Qhov muag tsis pom kev ntawm qhov sib txawv me me yuav ua rau muaj teeb meem hauv kev tsim khoom thiab kev saib xyuas.
2. Kev ua haujlwm hluav taws xob
Kev ua haujlwm hluav taws xob ntawm qhov txuas feem ntau suav nrog kev txwv tam sim no, kev tiv thaiv kev tiv thaiv, kev tiv thaiv hluav taws xob, thiab lub zog dielectric, thiab lwm yam. Thaum txuas lub zog hluav taws xob siab, xyuam xim rau qhov txwv tam sim no ntawm cov khoom txuas; Thaum xa cov teeb liab siab xws li LVDS, PCIe, thiab lwm yam, xyuam xim rau kev tiv thaiv kev tiv thaiv. Lub connector yuav tsum muaj qhov sib tiv tauj tsawg thiab tsis tu ncua, feem ntau kaum ntawm mΩ mus rau pua pua mΩ.
3. Kev ua haujlwm ib puag ncig
Kev ua haujlwm ib puag ncig ntawm cov khoom txuas feem ntau suav nrog kev ua haujlwm kub, av noo, tshuaj tsuag ntsev, kev co, kev poob siab, thiab lwm yam. Xaiv raws li qhov tshwj xeeb daim ntawv thov ib puag ncig. Yog hais tias daim ntawv thov ib puag ncig yog cov av noo, qhov yuav tsum tau ua rau cov av noo thiab ntsev tsuag ntawm lub connector yog siab los tiv thaiv cov hlau hu ntawm connector los ntawm corroded. Hauv kev tswj hwm kev lag luam, qhov yuav tsum tau ua rau kev tiv thaiv kev vibration thiab kev cuam tshuam kev ua haujlwm ntawm lub connector yog siab, thiaj li tiv thaiv cov connector los ntawm ntog tawm thaum lub sij hawm vibration txheej txheem.
4. Mechanical zog
Cov khoom siv hluav taws xob ntawm cov khoom sib txuas muaj xws li kev siv dag zog, cov neeg kho tshuab foolproof, thiab lwm yam. Mechanical foolproof tseem ceeb heev rau lub connector. Thaum ntsaws rau hauv rov qab, nws yuav ua rau irreversible kev puas tsuaj rau lub Circuit Court!
