NEMA Connectors

NEMA connectors xa mus rau lub hwj chim plugs thiab receptacles siv nyob rau hauv North America thiab lwm lub teb chaws uas ua raws li cov qauv teev los ntawm lub NEMA (National Electrical Manufacturers Association).NEMA cov qauv faib cov plugs thiab receptacles raws li qhov ntsuas amperage thiab qhov ntsuas hluav taws xob.

Hom ntawm NEMA connectors

Muaj ob lub ntsiab ntawm NEMA connectors: ncaj-blade los yog tsis-locking thiab nkhaus-blade los yog twist-locking.Raws li lub npe qhia, cov hniav ncaj nraim los yog tsis-locking connectors yog tsim los rub tawm ntawm lub receptacles yooj yim, uas, thaum yooj yim, kuj txhais tau hais tias qhov kev twb kev txuas tsis ruaj ntseg.

NEMA 1

NEMA 1 connectors yog ob-prong plugs thiab receptacles tsis muaj tus pin hauv av, lawv tau nyob ntawm 125 V thiab nrov rau kev siv hauv tsev, xws li hauv cov khoom siv ntse thiab lwm yam khoom siv hluav taws xob me me, vim tias lawv cov qauv tsim thiab dav dav.

NEMA 1 plugs kuj sib xws nrog cov tshiab NEMA 5 plugs, uas ua rau lawv xaiv saum toj kawg nkaus rau cov tuam txhab.Qee qhov feem ntau NEMA 1 connector suav nrog NEMA 1-15P, NEMA 1-20P, thiab NEMA 1-30P.

NEMA 5

NEMA 5 connectors yog peb-theem circuits nrog kev sib txuas nruab nrab, kev sib txuas kub, thiab xaim hauv av.Lawv raug ntsuas ntawm 125V thiab feem ntau siv hauv cov khoom siv IT xws li routers, khoos phis tawj, thiab lub network hloov.NEMA 5-15P, lub hauv paus version ntawm NEMA 1-15P, yog ib qho ntawm cov khoom siv feem ntau siv hauv Asmeskas.

NIM 14

NEMA 14 connectors yog plaub-xaim txuas nrog ob lub xov hlau kub, ib lub xov hlau nruab nrab, thiab tus pin hauv av.Cov no muaj qhov ntsuas amperage xws li 15 amps txog 60 amps thiab qhov ntsuas hluav taws xob ntawm 125/250 volts.

NEMA 14-30 thiab NEMA 14-50 yog cov khoom siv ntau tshaj plaws ntawm cov ntsaws ruaj ruaj, siv rau hauv qhov chaw tsis muaj qhov xauv xws li hauv tshuab ziab khaub ncaws thiab hluav taws xob ntau.Zoo li NEMA 6-50, NEMA 14-50 connectors kuj siv los them cov tsheb fais fab.

NEMA TT-30

NEMA Travel Trailer (lub npe hu ua RV 30) feem ntau yog siv los hloov hluav taws xob los ntawm lub zog hluav taws xob mus rau RV.Nws muaj qhov taw qhia tib yam li NEMA 5, uas ua rau nws sib haum nrog ob lub NEMA 5-15R thiab 5-20R receptacles.

Cov no feem ntau pom nyob rau hauv RV chaw ua si raws li tus qauv rau kev ua si tsheb.

Lub caij no, cov khoom siv xauv xauv muaj 24 subtypes, uas suav nrog NEMA L1 txog NEMA L23 nrog rau Midget Locking plugs lossis ML.

Qee qhov kev sib txuas ntau tshaj plaws yog NEMA L5, NEMA L6, NEMA L7, NEMA L14, NEMA L15, NEMA L21, thiab NEMA L22.

NEMA L5

NEMA L5 connectors yog ob-ncej connectors nrog grounding.Cov no muaj qhov ntsuas hluav taws xob ntawm 125 volts, ua rau lawv haum rau RV them.NEMA L5-20 feem ntau yog siv rau kev lag luam chaw uas muaj kev vibrations yuav tshwm sim, xws li nyob rau hauv campsites thiab marinas.

NEMA L6

NEMA L6 yog ob-ncej, peb-xaim txuas yam tsis muaj kev sib txuas nruab nrab.Cov khoom sib txuas no raug ntsuas ntawm 208 volts lossis 240 volts thiab feem ntau siv rau cov tshuab hluav taws xob (NEMA L6-30).

NEMA L7

NEMA L7 connectors yog ob-ncej txuas nrog grounding thiab feem ntau yog siv rau lub teeb pom kev zoo (NEMA L7-20).

NEMA L14

NEMA L14 connectors yog peb-ncej, grounded connectors nrog ib tug voltage ntsuam xyuas ntawm 125/250 volts, lawv feem ntau yog siv nyob rau hauv loj suab systems nrog rau cov me me generators.

NEMA L-15

NEMA L-15 yog plaub-ncej txuas nrog cov xaim hauv av.Cov no yog cov khoom siv tiv thaiv huab cua uas feem ntau siv rau kev lag luam hnyav.

NEMA L21

NEMA L21 connectors yog plaub-ncej connectors nrog hlau grounding nyob ntawm 120/208 volts.Cov no yog tamper-resistant receptacles nrog ib tug watertight foob uas tsim nyog siv nyob rau hauv ib puag ncig ntub dej.

NEMA L22

NEMA L22 connectors muaj plaub-ncej configuration nrog hlau grounding thiab ib tug voltage ntsuam xyuas ntawm 277/480 volts.Cov no feem ntau siv rau hauv cov cav tov thiab cov tshuab hluav taws xob.

Lub koom haum National Electrical Manufacturer's Association tau tsim lub rooj sib tham naming los ua qauv NEMA connectors.

Tus lej muaj ob ntu: tus lej ua ntej khiav nrawm thiab tus lej tom qab khiav ceev.

Thawj tus lej sawv cev rau kev teeb tsa ntsaws, uas suav nrog qhov ntsuas hluav taws xob, tus lej ntawm tus ncej, thiab cov xov tooj ntawm tes.Ungrounded connectors muaj tib tus xov tooj ntawm cov xov hlau thiab ncej vim lawv tsis xav tau ib tus pin hauv av.

Saib daim ntawv qhia hauv qab no rau kev siv:

Lub caij no, tus lej thib ob sawv cev rau qhov ntsuas tam sim no.Tus qauv amperages yog 15 amps, 20 amps, 30 amps, 50 amps, thiab 60 amps.

Txhawm rau muab qhov no rau hauv qhov kev xav, NEMA 5-15 txuas yog ob-ncej, ob-xaim txuas nrog qhov ntsuas hluav taws xob ntawm 125 volts thiab qhov ntsuas tam sim no ntawm 15 amps.

Rau qee qhov sib txuas, lub rooj sib tham naming yuav muaj cov ntawv ntxiv ua ntej tus lej thib ib thiab / lossis tom qab tus lej thib ob.

Thawj tsab ntawv, "L" tsuas yog pom nyob rau hauv cov khoom sib txuas los qhia tias nws yog hom xauv qhov tseeb.

Tsab ntawv thib ob, uas tuaj yeem yog "P" lossis "R" qhia seb qhov txuas yog "Plug" lossis "Receptacle".

Piv txwv li, NEMA L5-30P yog lub xauv ntsaws nrog ob tug ncej, ob lub xov hlau, qhov ntsuas tam sim no ntawm 125 volts, thiab ib qho amperage ntawm 30 amps.
