Ferrule

Yog li dab tsi yog ferrule?Feem ntau hais lus, txhua hom pluaj lossis clip siv los txuas, txhawb nqa lossis ruaj ntseg khoom ua ke.Nws yog ib qho kev txhais dav dav uas npog txhua yam los ntawm cov hlua siv rau qhov kawg ntawm cov hlua khi kom lawv tsis txhob txav mus, kom ruaj khov hlau clips. siv los txuas hlau hlua ua ke.Tab sis nyob rau hauv lub ntiaj teb no ntawm hlau, ferrules muaj ib tug tshwj xeeb txhais lus thiab ua hauj lwm txawv heev lub hom phiaj tshaj ferrules siv rau cov neeg kho tshuab ntshiab.
Ib lub hlau ferrule yog ib lub raj hlau mos uas yog crimped mus rau qhov kawg ntawm ib txoj hlua khi los txhim kho cov yam ntxwv ntawm kev sib txuas ntawm cov hlau.Feem ntau ferrules yog ua los ntawm tooj liab, feem ntau yog tinned.Ferules yog qhov loj me rau ib qho kev ntsuas ntawm cov hlau, ob qho tib si hauv txoj kab uas hla. thiab ntev.Txawm li cas los xij, lub ferrule yog ntau tshaj ib lub tog raj kheej yooj yim - nws muaj ib daim di ncauj los yog flare ntawm ib kawg uas sau thiab sib sau ua ke ib leeg strand ntawm hlau thaum lub ferrule tso.
Lub flare nyob rau hauv feem ntau ferrules tsis tshwm sim tam sim ntawd vim hais tias nws yog feem ntau qhwv nyob rau hauv ib tug tapered yas cable nkag lub tes tsho.Lub tes tsho ua raws li ib tug kev hloov ntawm cov hlau rwb thaiv tsev thiab lub ferrule nws tus kheej, thiab kuj pab mus sib sau ib tug xoob strands rau hauv lub lumen. ferrule.Txawm li cas los xij, tsis zoo li ntau cov kev sib txuas ntawm cov tsoos crimp, lub tes tsho yas ntawm lub ferrule tsis compressed thaum lub sij hawm installation.Nws tseem nyob ib ncig ntawm lub rwb thaiv tsev thiab muab ib co degree ntawm strain nyem tom qab kev teeb tsa los ntawm kev txav lub vojvoog ntawm cov hlau tawm ntawm qhov kawg ntawm cov rwb thaiv tsev. .Feem ntau lub tes tsho ferrule yog xim-coded rau hlau loj nyob rau hauv tus qauv DIN 46228, uas, confusingly, muaj ob tug sib txawv codes, Fabkis thiab German, nyob rau hauv square millimeters rau tib lub cross-sectional cheeb tsam.
Yog hais tias lub ferrule suab nrov ntawm European tshaj tshaj li ib tug neeg Amelikas, yog vim li cas zoo.Yuav kom tau txais CE daim ntawv pov thawj, cov khoom siv hluav taws xob yuav tsum tau txiav cov hlua khi rau hauv cov ntsia hlau los yog lub caij nplooj ntoos hlav terminals nrog ferrules.Tsis muaj kev cai lij choj hauv Teb Chaws Asmeskas, yog li ntawd. Kev siv cov ferrules hauv Teb Chaws Asmeskas cov khoom siv tsis yog ib txwm muaj.Tab sis ferrules muaj qhov zoo tshwj xeeb uas nyuaj rau kev tsis lees paub, thiab lawv txoj kev saws me nyuam zoo li nthuav dav vim tias lawv ua kom zoo engineering.
Yuav kom nkag siab yuav ua li cas, clamp ib qho luv luv ntawm insulated stranded hlau ntawm tej gauge.Stranded hlau yog saj zawg zog, uas yog ib tug ntawm cov laj thawj vim li cas stranded hlau yog siv es tsis txhob ntawm cov khoom hlau nyob rau hauv mobile daim ntawv thov thiab lub peev xwm rau kev co.Tab sis nws tseem me ntsis txhav. , nyob rau hauv ib feem vim hais tias cov rwb thaiv tsev wraps tus neeg xyuas pib cov strands, ua kom lawv nyob rau hauv kev sib cuag thiab ua kom tus neeg strands twisted los yog nteg tawm.Tam sim no tev tawm me ntsis ntawm cov rwb thaiv tsev los ntawm ib kawg.Koj yuav pom tias nyob rau hauv feem ntau cov nteg ntawm lub strands yog yam tsawg kawg yog ib feem cuam tshuam - lawv unravel me ntsis.Strip ntau ntawm cov rwb thaiv tsev thiab cov strands tau ntau thiab ntau sib cais. Tshem tag nrho cov rwb thaiv tsev thiab cov conductors yuav plam tag nrho cov qauv kev ncaj ncees thiab poob rau hauv ib tug neeg strands.
Qhov no yog qhov yooj yim teeb meem uas ferrules daws: Tom qab stripping, lawv tuav ib tug nruj daim ntawv cog lus ntawm cov strands nyob rau hauv tus neeg xyuas pib thiab tso cai rau kev sib txuas ua nws tag nrho cov rated tam sim no.Yog tsis muaj ferrules, stripped strands compressed nyob rau hauv cov ntsia hlau terminals yuav splay, txo tus naj npawb. ntawm ib leeg strands uas ua rau kev sib cuag nrog lub davhlau ya nyob twg.Qhov kev txiav tawm no muaj kev tiv thaiv ntau dua li kev sib txuas ferrule kom zoo.Qhov kev ua tau zoo ntawm cov hlua khi nrog ferrules yog qhov zoo dua li tsis muaj ferrules.Source: Weidmüller Interface GmbH & Co. KG
Kev sib txuas ntawm ferrule ua ntau dua li tsuas yog txo qhov tsis kam, txawm li cas los xij.Raws li nrog lwm cov kev sib txuas crimp, cov hlua hlau nyob rau hauv ib qho kev siv ferrule kom raug raug siab heev, ncab axially thiab deforming radially nyob rau hauv tus txheej txheem.Tensile kev txiav txim siab mus rhuav tshem thiab tshem tawm oxidation nto. cov strands, thaum radial compression nyhav kom tshem tawm cov huab cua ntawm cov strands.Cov no yuav ua rau crimped kev sib txuas zoo dua ntawm resisting oxidation dua uncrimped xov hlau, ua rau lub neej ntawm kev sib txuas.
Yog li hoops txoj hauv kev mus rau tsev neeg gamers?Zuag qhia tag nrho, kuv xav hais tias yog.Ferules muaj qhov zoo tshaj plaws ntawm cov hlua khi ib txwm, thiab hauv cov ntawv thov tam sim no kuv yuav lo siv lawv nrog cov ntsia hlau terminals, lossis nyob qhov twg hauv daim ntaub thaiv qhov kev ntxhov siab. relieved.Plus, lawv muab tej yaam num ib tug huv si, kev saib, yog li kuv nyiam nrog lawv nyob rau hauv kuv stranded hlau kev twb kev txuas txawm tias daim ntawv thov tsis tseem ceeb.Tau kawg, tooling lub ferrules tsis yog tsis muaj nqi, tab sis ntawm $30 rau ib cov khoom siv. nrog ntau yam ferrules thiab cov cuab yeej ratcheting crimping kom zoo, uas tsis yog qhov phem.
"Cov xaim xaim yog hloov pauv tau, uas yog ib qho laj thawj rau kev siv cov xaim xaim tsis siv cov xaim khoom hauv cov ntawv thov txawb thiab lub peev xwm rau kev co."

Yuav ua li cas txog tinning qhov kawg ntawm cov strands?Qhov no piv rau ferrules li cas?Nws kuj tshem tawm oxidation thiab tshem tawm cov huab cua nyob ib ncig ntawm cov strands.
Kuv yeej ib txwm xav tias qhov no yog ib lub tswv yim phem, txij li solder yog qhov ua tau zoo nkauj heev kuj.
Nws ua hauj lwm, tab sis tsis muaj arguably qhov tseem ceeb tshaj plaws mechanical strain nyem.Kuv twb pom ntau tinned hlau xaus uas tawg yooj yim ntawm kev hloov ntawm cov tinned thiab tsis-tinned seem.
Ua kom qhov teeb meem loj dua, qhov kawg ntawm cov solder muab qhov kev ntxhov siab uas ua rau nws yooj yim dua rau kev tawg
Ua kom qhov teeb meem loj dua, solder yog malleable thiab inelastic, yog li txawm tias lub hau ntswj yog nruj, txhua yam khoom deformation yuav ua rau kev sib txuas ua kom xoob xoob.
Ua kom qhov teeb meem loj dua, qhov kawg ntawm cov solder muab qhov kev ntxhov siab uas ua rau nws yooj yim dua rau kev tawg
Yog tias kuv nco qab kom raug, nws ua rau ib feem ntawm cov hlau nyob rau hauv qhov kawg ntawm cov solder feem ntau yuav tawg.Yog li koj yuav muaj qhov zoo nkauj zoo, tab sis cov hlau yuav tawg sai dua.
yog.Solder tuaj yeem wick hlau rau hauv rwb thaiv tsev thiab ua ib qho chaw tsis muaj zog rau qaug zog.
Ob peb lub hlis dhau los, NASA cov phau Vajlugkub tau qhia meej tias tsis txhob cia lub solder nce 1-2 hli nyob rau hauv pem hauv ntej ntawm cov hlau rwb thaiv tsev.Thaum cov hlau yuav tsum tau txuas nrog cov cuab yeej mowing, yam koj ua yog siv Litze hlau (tsuas yog pheej yig dua, tsis yog tus kheej insulated strand hom) vim tias nws yog xoob lub qhov txhab los ntawm ntau pua ntawm filaments.Tom qab ntawd koj muaj cov xaim uas hloov tau yooj yim kom tsis txhob tawg.
Litz hlau, raws li lub npe qhia, yog ib pob khoom ntawm ib tus kheej insulated xov hlau.Tsis muaj "pheej yig version" ntawm uninsulated strands, vim hais tias defeats lub hom phiaj ntawm litz hlau.Koj tsuas xav tau siab strand suav los yog "super saj zawg zog" hlau. , nws tsis ua ntau rau cov chaw tsis muaj zog uas tsim los ntawm vuam.
Qhov ntawd tsis yog ib qho laj thawj yog vim li cas koj yuav tsum tsis txhob muab cov xov hlau nyob hauv cov ntsia hlau terminals lawm.Yog li ntawd, nws yog qhov zoo yog tias cov xov hlau tsis khoov lossis vibrate nyob ze ntawm lub terminals.Qhov teeb meem yog tias cov hlau txuas tau nkag mus ("txias ntws. ”) Nws deforms dhau lub sij hawm, qhov sib koom ua ke poob compression, thiab tom qab ntawd koj muaj kev sib txuas xoob thiab txhua yam koj xav tau.
tsis zoo.Nws tsim ib qho chaw tsis muaj zog tam sim ntawd tom qab qhov sib koom ua ke, thiab dhau-bending lub cable tuaj yeem ua rau lub cable puas ntawm qhov taw tes meej.Lub tes tsho (ferrules) nrog cov yas xaus yog yooj yim dua rau ntawm lub cable txawm tias koj rub tawv ntawm lub cable.
Tin tsis yog ib qho khoom tiag tiag, tab sis yuav deform thaum lub sijhawm.Vim li ntawd, kev sib txuas uas tau nruj thaum lub sijhawm teeb tsa tuaj yeem xoob lub sijhawm.loose kev twb kev txuas -> siab dua -> kub dua -> tsawg dua cov khoom tin -> looser kev twb kev txuas...koj paub. dab tsi tshwm sim
Tsis tas li ntawd, cov tin tuaj yeem khiav mus rau hauv cov rwb thaiv tsev thiab tsim ib qho chaw nyuaj ntawm qhov chaw deb ntawm lub davhlau ya nyob twg - yog tias koj tsis muaj hmoo, qhov no yog qhov uas cov hlua ntawm cov hlau pib tawg, ua rau pom qhov tsis xws luag.
Qhov teeb meem tseem ceeb, ntxiv rau qhov tseeb tias cov tin lossis cov pa tin + cov hmoov txhuas sib xyaw yog mos heev, tin "txias ntws" tawm ntawm cov ntsia hlau los ntawm kev caij tsheb kauj vab thiab kev ntxhov siab, tsis ntev los yog tom qab tsim kev tiv thaiv kev tiv thaiv.
Qhov thib peb yog vim li cas kuv tau hnov ​​​​txog soldering yog tias lub solder yog mos heev thiab dhau sij hawm cov ntsia hlau txuas yuav loosen.
Txias ntws nyob rau hauv siab yog tib yam vim li cas cov qub txhuas fais fab qaum yog li txaus ntshai.Thaum lub sij hawm, kev sib txuas ua xoob, tsis kam nce + kev sib txuas tsis zoo tuaj yeem ua rau arcing.
Kuv yeej tsis nyiam nrhiav nws ntawm qhov chaw.Solder yog ib qho nyuaj thiab du, yog li lub davhlau ya nyob twg thaiv tsis compress thiab tuav nws zoo li softer stranded tooj liab.Ferrule crimpers muab serrations rau ntawm crimp, yog li nws grips zoo dua solder.
Tinned hlau rau cov ntsia hlau terminals yog ib lub tswv yim phem vim hais tias txawm nyob rau hauv chav tsev kub lub solder yuav hloov me ntsis nyob rau hauv lub siab thiab raws li qhov kub thiab txias yog cycled, yuav ntws tawm ntawm qhov sib koom ua ke txo qhov kev sib cuag cheeb tsam thiab ua rau kom cov kev tiv thaiv, yog li cua sov, ua rau ib tug kev sib cuag. zoo tswv yim cuam tshuam.
Tin plating yog softer dua liab qab tooj liab.Vim li ntawd, screws yuav plam lub sij hawm sai dua ferrules los yog lugs.
Kuv paub tias nyob rau hauv cov teb chaws Europe, stranded nyob ntawm tej feem ntau yog tinned ua ntej ntau yam tsis ua hauj lwm los yog hlawv, thiab crimping yog tam sim no ib qho teeb meem.
Ua rau muaj teeb meem nrog kev ntxhov siab ... feem ntau lov tag nrho qhov twg lub solder xaus, raws li nws tso cai rau cov ntse heev khoov (soldered nyob ntawm tej yog ib qho nyuaj, tsis-soldered xov hlau tsis yog….
Kuv yeej tsis xav kom cov hlau nplaum.Tshwj xeeb yog tias muaj kev vibration lossis txawm tias txav mus los, koj lub cable tuaj yeem tawg hauv lub sijhawm luv luv.
