Tus pin ua haujlwm ntawm 4-pin automotive connectors txawv nyob ntawm daim ntawv thov scenarios. Cov hauv qab no yog cov kev faib ua feem ntau thiab cov lus piav qhia ntxaws:
I. Fais fab kis hom
Lub davhlau ya nyob twg zoo ntawm DC fais fab mov (DC +) thiab lub davhlau ya nyob twg tsis zoo (DC-)
Muaj nuj nqi: Siv rau siab-voltage lossis qis-voltage DC fais fab kis, xws li them cov roj teeb lub tsheb tshiab thiab cov khoom siv hluav taws xob rau ntawm - khoom siv.
II. Hwj chim kis tau tus mob Class
Kev lees paub kev them nyiaj yug (CC1/CC2)
Muaj nuj nqi: Tshawb xyuas qhov kev sib txuas ntawm rab phom thiab lub tsheb kom paub meej tias kev nyab xeeb ntawm kev them nyiaj.
Sensor signals (xws li kub, kev sib hloov ceev)
Muaj nuj nqi: Xa cov teeb liab analog thiab saib xyuas lub tsheb xwm txheej.
Yam xwm txheej:
Hauv qee qhov txuas, tus pins tuaj yeem txuas nrog cov ntsuas kub (xws li cov cim ntsuas kub los ntawm DC charging chaw nres nkoj).
Hauv BMW tsheb series, 9 tus pins yuav siv tau rau kev xa cov cav sib hloov ceev.
III. Tswj thiab pab pawg muaj nuj nqi
Pib Pib Teeb Kab
Function: Xa cov lus txib pib los tswj lub cav ignition.
Cov xwm txheej zoo ib yam: Hauv ib qho - qhov hloov pauv tseem ceeb, plaub lub xov hlau yuav suav nrog lub davhlau ya nyob twg zoo, qhov tsis zoo, qhov txuas tsis zoo, kab sib txuas lus, thiab pib kab teeb liab.
Video Signal Transmission (Dashcam)
Muaj nuj nqi: Xa cov teeb liab video ntes los ntawm lub koob yees duab.
Hom scenario:
Nyob rau hauv lub rear cable ntawm plaub -pin dashboard lub koob yees duab recorder, ob lub pins yog qhov zoo thiab tsis zoo video terminals, thiab lwm yam ob pins yog lub zoo thiab tsis zoo lub hwj chim terminals.
Tsib -pin connector tuaj yeem ntxiv cov ntaub thaiv npog sab nraud los txhim kho cov teeb liab ruaj khov.
Shielding hlau (tsib-pin connector)
Muaj nuj nqi: Txo cov hluav taws xob cuam tshuam (EMI) thiab xyuas kom cov teeb liab kis tau zoo.
Tej yam xwm txheej: Hauv tsib -pin connector ntawm dashboard lub koob yees duab recorder, lub shielding hlau tej zaum yuav tswj tus pab txoj kab hloov los yog daim duab flipping muaj nuj nqi.
