A pog pinlos yogspring-loaded pinyog ib hom hluav taws xob connector mechanism uas yog siv nyob rau hauv ntau niaj hnub kev siv hluav taws xob thiab cov khoom siv hluav taws xob kuaj kev lag luam. Lawv yog siv rau lawv cov kev txhim kho durability dua lwm yam hluav taws xob tiv tauj thiab resilience ntawm lawv cov hluav taws xob kev twb kev txuas rau mechanical shock thiab vibration.
Lub npepog pinlos ntawm tus pin zoo ib yam li pogo stick - lub caij nplooj ntoos hlav helical nyob rau hauv tus pin siv lub zog tas li tawm tsam sab nraum qab ntawm lub mating receptacle los yog hu rau phaj, tiv thaiv kev tsis xav txav uas yuav ua rau muaj kev sib cuam tshuam. Lub caij nplooj ntoos hlav helical no ua rau pogo pins tshwj xeeb vim tias feem ntau lwm hom pin mechanisms siv lub caij nplooj ntoos hlav cantilever lossis lub tes tsho nthuav dav.
Ib txoj hauv kev sib txuas ua tiav yuav tsum muaj kev sib txuas lus rau tus pin kom koom nrog, uas yog hu ua aphiajlos yogav. Lub hom phiaj pogo muaj lub tiaj tus lossis concave hlau nto, uas, tsis zoo li cov pins, tsis muaj qhov txav txav. Cov hom phiaj yuav yog cov khoom sib cais hauv kev sib txuas ua tiav, lossis hauv cov ntawv luam tawm Circuit Board, tsuas yog thaj chaw plated ntawm lub rooj tsavxwm.
Caij nplooj ntoos hlav-loaded pins yog precision qhov chaw fabricated nrog ib tug tig thiab spinning txheej txheem uas tsis yuav tsum tau ib tug pwm, yog li tso cai rau zus tau tej cov me me ntawm tus nqi qis.
Qauv
Ib qho yooj yim caij nplooj ntoos hlav-loaded tus pin muaj 3 qhov tseem ceeb: aplunger, chim, thiabcaij nplooj ntoos hlav. Thaum lub zog siv rau tus pin, lub caij nplooj ntoos hlav yog compressed thiab lub plunger txav mus rau hauv lub thoob. Cov duab ntawm lub thoob khaws cov plunger, txwv tsis pub lub caij nplooj ntoos hlav thawb nws tawm thaum tus pin tsis kaw rau hauv qhov chaw.
Hauv kev tsim cov hluav taws xob tiv tauj, ib qho kev sib txhuam yuav tsum tau tuav lub connector nyob rau hauv qhov chaw thiab khaws cov kev sib cuag. Txawm li cas los xij, kev sib txhuam siab yog qhov tsis xav tau vim tias nws ua rau muaj kev ntxhov siab thiab hnav ntawm qhov chaw sib cuag thiab cov vaj tsev. Yog li, lub zog ib txwm muaj tseeb, feem ntau nyob ib puag ncig 1 newton, yuav tsum tsim kom muaj kev sib txhuam no. Txij li thaum lub caij nplooj ntoos hlav-loaded tus pin yuav tsum muaj qhov sib txawv me ntsis ntawm lub plunger thiab lub thoob kom nws tuaj yeem xaub tau yooj yim, kev cuam tshuam ib ntus tuaj yeem tshwm sim thaum muaj kev vibration lossis txav. Txhawm rau tiv thaiv qhov no, lub plunger feem ntau muaj qhov qaij me me kom ntseeg tau tias muaj kev sib txuas tsis tu ncua.
Ntau lub tuam txhab tau tsim lawv cov kev hloov pauv ntawm tus qauv tsim, feem ntau los ntawm kev sib txawv ntawm qhov sib txawv ntawm lub plunger thiab caij nplooj ntoos hlav. Piv txwv li, ib lub pob tuaj yeem raug ntxiv ntawm ob lub ntsiab lus, los yog lub plunger yuav muaj lub kaum sab xis lossis lub taub hau.
Lub plunger thiab chim ntawm pogo pins feem ntau yog siv tooj dag lossis tooj liab los ua cov khoom siv hauv cov txheej txheem ntawm cov nickel nyias.
Raws li ib txwm muaj nyob rau hauv cov khoom siv hluav taws xob, cov tuam txhab lag luam feem ntau siv cov plating kub uas txhim kho cov kav ntev thiab kev sib cuag.
Cov springs feem ntau yog ua los ntawm tooj liab alloys los yog caij nplooj ntoos hlav steel.
Lub caij nplooj ntoos hlav-loaded connectors yog siv rau ntau yam kev siv, hauv ob qho tib si kev lag luam thiab cov neeg siv khoom siv hluav taws xob:
Board-to-board connectors (feem ntau mus tas li)
Ingress-tiv thaiv connectors nyob rau hauv cov neeg siv khoom, xws li smartwatches, rugged computers
Roj teeb terminals ntawm laptops
Sib nqus them lossis cov teeb liab connectors, xws li lub laptop docks, thiab chargers(saib§ Kev sib xyaw nrog cov hlau nplaum)
High-frequency connectors, xws li antennas, saib connectors
Printed Circuit Board kuaj
Integrated Circuit Court kuaj
Kev ntsuam xyuas hauv Circuit Court
Kev sim roj teeb
Lwm yam kev ntsuas hluav taws xob
Connector kev npaj

Thaum pogo pins siv nyob rau hauv ib tug connector, lawv feem ntau yog teem nyob rau hauv ib tug ntom array, txuas ntau tus neeg nodes ntawm ob hluav taws xob circuits. Lawv feem ntau pom muaj nyob rau hauv cov cuab yeej ntsuas tsis siv neeg nyob rau hauv daim ntawv ntawm lub txaj ntawm cov ntsia hlau, qhov chaw uas lawv pab txhawb kev sib txuas ceev, txhim khu kev qha ntawm cov cuab yeej hauv kev sim (DUTs).[10]Nyob rau hauv ib qho kev teeb tsa high-density, lub array siv lub nplhaib uas muaj ntau pua lossis ntau txhiab tus pins pogo; cov cuab yeej no qee zaum hu ua apog.
Lawv kuj tuaj yeem siv rau kev sib txuas mus tas li, piv txwv li, hauv Cray-2 supercomputer.
Thaum siv rau hauv cov ntawv thov kev ua tau zoo tshaj plaws, pogo pins yuav tsum tau ua tib zoo tsim kom tsis txhob muaj kev ntseeg siab thoob plaws ntau lub voj voog mating / unmating tab sis kuj muaj kev ntseeg siab ntawm cov teeb liab hluav taws xob. Cov pins yuav tsum yog ib qho nyuaj, tsis tau plated nrog ib yam khoom (xws li kub) uas muab kev sib cuag txhim khu kev qha. Nyob rau hauv lub cev ntawm tus nuv, lub plunger yuav tsum ua kom zoo hluav taws xob sib cuag nrog lub cev tsam lub siab dua lub caij nplooj ntoos hlav nqa lub teeb liab (nrog rau lub undesirable inductance uas lub caij nplooj ntoos hlav sawv cev). Kev tsim ntawm pogo pins siv rau hauv kev sib tw-impedance circuits yog qhov nyuaj heev; txhawm rau tswj tus cwj pwm kom raug impedance, cov pins qee zaum teem nrog ib lub teeb liab-nqa tus pin ncig los ntawm plaub, tsib, lossis rau tus pins hauv av.
