Automotive fuses yog tus saib xyuas lub rooj vag thiab lub cev tiv thaiv tsheb hluav taws xob. Thaum twg ib qho luv luv lossis surge hem cov khoom siv hluav taws xob ntawm lub tsheb niaj hnub lossis tsheb thauj khoom, lub fuse tau npaj txhij los pov nws tus kheej rau hauv qhov hluav taws kub.
Thaum ua li ntawd, lub fuse yuav siv cov mos txwv ua piv txwv rau qhov muaj txiaj ntsig, nyuaj, lossis yam khoom tsis tseem ceeb, xws li lub suab tsheb lossis lub suab nrov. Qhov no feem ntau ua rau poob haujlwm ib ntus. Fuses, txawm li cas los xij, pheej yig thiab feem ntau yooj yim los hloov. Kev rov ua tsis tiav ntawm lub fuse ntawm tib lub voj voog feem ntau qhia txog qhov teeb meem tshwm sim.
Txhua lub tsheb fuses tsis zoo ib yam
Automotive fuses txawv ntawm cov qauv tsim thiab kev ntsuas tam sim no, tab sis lawv txhua tus raws li tus qauv ATO thiab ATC hniav hom fuses uas Littelfuse patented hauv xyoo 1970s. Lawv muaj qhov zoo sib xws rau thawj ATO fuses, thiab ntau daim ntawv thov tseem siv tus qauv ATO thiab ATC fuses. Hom sib txawv feem ntau nyob rau hauv qhov loj thiab tus naj npawb ntawm cov terminals. Lub cev loj fuses feem ntau yog siv rau hauv cov ntawv thov tam sim no.
Yav dhau los, cov tsheb feem ntau siv iav raj thiab Bosch fuses. Lawv tau pom niaj hnub no hauv cov tsheb qub uas tseem nyob ntawm txoj kev.
Ib lub raj fuse yog capped los ntawm hlau terminals nrog ib tug hlau sawb hla mus rau hauv nruab nrab. Bosch fuses kuj yog cylindrical, tab sis lawv yog ua los ntawm cov khoom siv ceramic nrog cov hlau sawb ntawm qhov chaw.
Txawm hais tias nws tuaj yeem hloov tau ATO fuse nrog lwm tus ATO fuse, qhov no tuaj yeem txaus ntshai heev yog tias hloov pauv amperage fuse tsis raug.
Ib yam li ntawd, hloov lub Bosch fuse nrog lub khob hom American-style yog qee zaum lub cev ua tau, tab sis ua raws li qhov ntsuas amperage yog qhov tseem ceeb. Tsis tas li ntawd, ib lub khob iav raj fuse feem ntau tsis haum zoo rau hauv lub fuse yas dhos tsim los rau cov kaus mom kawg.
Type of Blade Fuses
Rau txhua cov hniav fuses, lub tsev yog opaque lossis meej. Thaum lub vaj tse meej meej, nws feem ntau yog ib qho yooj yim los qhia seb lub fuse puas phem vim tias cov hlau nplaum uas txuas ob lub terminals pom. Yog tias lub sawb tawg, lub fuse tau tawg.
Txhua lub tsheb thiab tsheb thauj khoom niaj hnub siv ib lossis ntau dua ntawm cov nram qab no ntawm cov hniav fuses, teev nyob rau hauv qhov kev txiav txim ntawm qhov loj me.
Maxi (APX) Heavy-duty Fuses
- Ntau hom hniav fuse.
- Siv rau hauv daim ntawv thov hnyav.
- Muaj nrog kev ntsuas amperage ntau dua li lwm cov hniav fuses.
Regular (ATO, ATC, APR, ATS) Fuses
- thawj thiab hom qauv ntawm cov hniav fuse. Cov fuses no dav dua lawv siab.
- Los ntawm ob hom tseem ceeb uas haum rau tib lub qhov. ATO fuses qhib rau hauv qab; ATC fuses muaj lub cev yas uas kaw.
- Pom nyob hauv cov tsheb niaj hnub thiab tsheb thauj khoom.
- Ntau daim ntawv thov pib hloov ATO thiab ATC fuses nrog mini fuses hauv xyoo 1990, tab sis lawv tseem muaj thoob plaws.
Mini
- Me me dua li cov hniav fuses ib txwm muaj tab sis muaj nyob thoob plaws ntau yam amperage.
- Kuj muaj nyob rau hauv qhov qis-profile mini version.
- Low-profile thiab tsis tu ncua mini fuses sib koom tib lub cev qhov siab thiab dav, tab sis lub spade terminals ntawm low-profile mini fuses NW nyuam qhuav dhau mus rau hauv qab ntawm lub cev.
Micro
- Micro2 fuses yog hom me tshaj plaws ntawm cov hniav fuse. Lawv siab tshaj qhov dav.
- Micro3 fuses loj dua Micro2, qis profile, thiab mini fuses. Lawv muaj peb spade terminals. Txhua hom hniav fuse siv ob lub terminals. Lawv kuj suav nrog ob lub ntsiab lus fuse, uas tso cai rau ib lub fuse los tuav ob lub voj voog zoo.
- Muaj nyob thoob qhov tsawg tshaj plaws ntawm kev ntsuas amperage.
Automotive Fuse Xim Coding
Nws tuaj yeem hloov pauv ATC fuse nrog lwm yam ATC fuse, txhua lub fuse nrog lwm yam mini fuse, thiab lwm yam. Txawm li cas los xij, qhov no tsis muaj kev nyab xeeb yog tias koj tsis phim cov kev ntsuas tam sim no. Txawm hais tias fuses tuaj yeem tshuab tau raws li kev ua haujlwm ib txwm muaj vim muaj hnub nyoog thiab hnav, lub tshuab tshuab feem ntau qhia tias muaj teeb meem tob dua.
Yog li, yog tias koj hloov lub tshuab hluav taws xob nrog lwm lub fuse nrog qhov ntsuas siab dua, koj yuav tiv thaiv lub fuse los ntawm tshuab dua tam sim ntawd. Txawm li cas los xij, koj kuj tseem yuav ua rau qee yam khoom siv hluav taws xob puas tsuaj lossis txawm tias pib hluav taws.
Nws muaj peb txoj hauv kev los qhia qhov amperage ntawm cov hniav hom fuse:
- Saib rau saum lub fuse rau qhov ntsuas amperage uas luam tawm lossis ntaus cim rau hauv cov yas.
- Saib xim ntawm lub cev fuse Yog tias qhov ntsuas tau hnav lawm.
- Kos daim duab fuse kom pom tias hom fuse nyob hauv qhov ntawd.
Xim thiab lub cev qhov ntev rau cov hniav fuses tau muab tso rau hauv DIN 72581, thiab tsis yog txhua qhov xim thiab qhov ntsuas amperage muaj nyob hauv txhua qhov ntau thiab tsawg.

Xim coding yog tus qauv yuav luag thoob plaws lub rooj tsavxwm rau ntau hom tsheb fuses, nrog rau ob qhov tshwj xeeb: 25 A thiab 35 A maxi fuses. Cov no yog grey thiab xim av, ntsig txog-xim uas kuj siv rau qis-amperage fuses. Txawm li cas los xij, maxi fuses tsis muaj nyob rau hauv 2 A lossis 7.5 A, uas yog cov kev ntsuam xyuas siv los ntawm cov xim, yog li tsis muaj qhov tsis meej pem.
Dab tsi Txog Fusible Txuas?
Fusible txuas ua tib yam haujlwm yooj yim li fuses, tab sis nyob rau hauv ib txoj kev sib txawv me ntsis. Hauv kev siv tsheb, qhov txuas fusible yog qhov ntev ntawm cov xaim uas yog ob peb lub ntsuas nyias nyias dua li cov hlau uas nws tsim los tiv thaiv. Thaum txhua yam ua tau zoo, qhov no ua rau qhov txuas fusible tsis ua haujlwm thiab tawg lub voj voog ua ntej qhov thaiv thaiv tsis tuaj yeem ua tsis tiav.
Fusible txuas kuj tau ntim rau hauv cov ntaub ntawv tshwj xeeb uas tsim los kom tsis txhob raug hluav taws thaum raug kub. Yog li, txawm hais tias tam sim no tsis tshua muaj siab nyob rau hauv cov xaim tsis tu ncua tuaj yeem ua rau hluav taws kub, qhov sib txuas fusible tsis tshua ua li ntawd.
Koj yuav pom cov kev sib txuas ntawm ntau qhov chaw hauv tsheb thiab tsheb thauj khoom, tab sis lawv feem ntau yog siv rau hauv cov ntawv thov high-amperage xws li pib lub cev muaj zog, uas tuaj yeem kos ntau pua amps. Thaum hom fusible txuas no tshuab, lub tsheb tsis pib lawm, tab sis kev pheej hmoo ntawm hluav taws tsawg dua. Hauv lwm daim ntawv thov, qhov txuas fusible yooj yim dua rau ntawm thiab hloov dua li cov xov hlau uas nws tau tsim los tiv thaiv.
Hloov Fuses thiab Fusible Txuas
Hloov lub fuse yog ib qho yooj yim, tab sis nws tseem ceeb heev kom paub tseeb tias koj hloov nws nrog qhov tseeb style thiab qhov ntsuas amperage. Hniav fuses yog qee zaum nyuaj rau rub tawm. Tseem, feem ntau cov tsheb tuaj nrog lub fuse rub lub cuab yeej hauv ib lub thawv fuse lossis txuas rau lub thawv fuse lub hau.
Txawm hais tias nws yooj yim heev los txheeb xyuas lub tsheb fuses ntawm qhov pom, daim ntawv qhia pom tuaj yeem pab koj txiav txim siab hom fuse koj xav tau.
Yog tias koj hloov lub fuse thiab nws tshuab dua, feem ntau muaj qee qhov teeb meem hauv qab. Hloov lub fuse nrog lub siab amperage fuse yuav kho qhov teeb meem ib ntus. Txawm li cas los xij, txheeb xyuas cov khoom muaj nyob rau ntawm lub voj voog ntawd thiab taug qab thiab kho qhov teeb meem hauv qab yog txoj hauv kev nyab xeeb dua mus.
Hloov cov kev txuas fusible feem ntau yog ib txoj haujlwm koom nrog ntau dua li rub lub fuse; lawv feem ntau bolted rau hauv qhov chaw thiab qee zaum nyuaj mus cuag. Koj tuaj yeem ua nws hauv tsev nrog cov cuab yeej tsim nyog yog tias koj tuaj yeem nrhiav lub cev qhov sib txuas ntawm lub tshuab fusible, tab sis nws tseem ceeb heev uas yuav tsum tau siv qhov hloov pauv kom raug.
Ib yam li ntawd, hloov qhov txuas txuas nrog qhov tsis raug yog qhov txaus ntshai. Hauv qhov xwm txheej zoo tshaj plaws, qhov txuas fusible yuav tsis muaj peev xwm tswj tau qhov amperage ntawm daim ntawv thov, thiab nws yuav poob tam sim ntawd. Hauv qhov xwm txheej phem tshaj plaws, koj tuaj yeem xaus nrog hluav taws.
Tsis txhob hloov qhov txuas txuas nrog hluav taws xob cable. Tsis yog txawm tias koj muaj pluaj hauv av lossis roj teeb cable pw ib puag ncig uas zoo li qhov loj thiab ntev. Hu rau lub khw muag khoom, muab daim ntawv thov rau lawv, thiab lawv yuav tuaj nrog qhov txuas fusible tsim los rau koj txoj haujlwm.
Fusible links feem ntau nqa cov nqi tam sim no. Yog li, kev ua haujlwm tsis zoo lossis nrog cov xaim hloov pauv lossis cable tuaj yeem ua rau hluav taws kub lossis kev kho tus nqi ntau dua thaum lwm cov xaim tsis ua haujlwm tom qab.
