Dab tsi yog Qhov Loj Loj Ntawm DC Power Jacks

DC fais fab jackstuaj nyob rau hauv ib tug ntau yam ntawm standard dimension rau cov neeg siv khoom thiab industrial electronics. Lawv qhov loj me yog txhais los ntawm sab nraud txoj kab uas hla thiab sab hauv tus pin txoj kab uas hla, thiab qhov sib txuam kom zoo tiv thaiv kev sib cuag tsis zoo lossis kho vajtse puas. Hobbyists, electronics assemblers thiab procurement neeg ua hauj lwm yuav tsum tau paub txog qhov loj me me los xaiv lub hwj chim adapters thiab hloov qhov (sockets).

Qhov feem ntau siv tshwj xeeb yog 5.5 hli txheej nrog 2.1 hli puab tus pin, sau li 5.5 × 2.1 hli. Lub jack no haum rau LED tsav tsheb, CCTV koob yees duab, routers me me thiab cov khoom siv hauv desktop. Tom ntej no yog 5.5 × 2.5 mm variant, uas nqa me ntsis siab dua tam sim no thiab tshwm sim ntawm cov laus laptops, sab nraud hard-disk enclosures thiab cov cuab yeej kuaj. Cov khoom me me xws li 3.5 × 1.35 mm yog qhov zoo rau cov ntsiav tshuaj, cov hais lus me me thiab cov khoom siv nqa tau yooj yim uas txuag chaw sab hauv. Me me 2.1 × 0.9 mm jacks pab cov khoom siv coj los siv tau yooj yim thiab cov khoom siv tes tuav.

Peb lo lus tseem ceeb siv tau los ntawm kev xaiv cov khoom siv:form factor, qhov ntsuas tam sim no, kev tiv thaiv polarity. Form factor piav qhia lub cev lub cev thiab qhov loj me ntawm txhua lub jack. Cov thoob loj dua muab lub zog ruaj khov dua, thaum cov qauv slim tsim tsim kom haum qhov chaw-txheej yas casings.

Qhov tshwj xeeb uas tsis yog-universal loj kuj tseem muaj rau cov khoom lag luam kaw. Kev cai jack qhov ntev txwv cov neeg siv rau cov khoom siv hluav taws xob qub. Thaum hloov lub tsho DC tawg, cov neeg ua haujlwm tsis tuaj yeem txiav txim qhov loj ntawm qhov muag ib leeg. Calipers yuav tsum ntsuas ob lub thoob sab nraud thiab sab hauv tus pin kom paub meej cov lus qhia tshwj xeeb. Plug thiab jack tsis sib haum yuav ua rau muaj kev cuam tshuam ntawm kev txiav hluav taws xob, overheating lossis luv-circuit txaus ntshai. Cov kws ua haujlwm ib txwm xaiv qhov ntau thiab tsawg rau kev tsim khoom loj los txiav cov nqi tiv thaiv thiab txhim kho qhov muaj nyob hauv tom qab muag khoom.
