Hauv kev tswj hwm hluav taws xob siab -siab txoj kev tsheb ciav hlau, lub tshuab hluav taws xob injector kis tau tus nqi qis - theem pulse signals (feem ntau 5V-12V nrog lub mem tes dav ntawm 0.5-2 ms) los ntawm ECU mus rau lub tog raj kheej injector solenoids yam tsis muaj attenuation. Lub teeb liab kev ncaj ncees txiav txim siab lub sijhawm txhaj tshuaj thiab lub sijhawm. Rau CAT C7 lub cav (siv hauv cov qauv 324D / 325D / 329D), harness tsis ua hauj lwm ua rau injector tsav tam sim no tsis txaus thiab ua rau cov lej kuaj tsis raug (xws li CID-FMI 166-03/04). Raws li lub Hoobkas cable nyob hauv Shenzhen, Guangdong, Mingching tau txheeb xyuas cov neeg siv khoom Philippine los qhia txog cov kev qhia tshwj xeeb uas xav tau rau CAT C7 injector harness ua raws li cov qauv tsim khoom qub.
Cov neeg siv khoom xav tau thiab Mingching's Technical Response
Cov neeg siv khoom Philippine tau tsa plaub qhov kev xav tau hais txog CAT C7 injector harness (thawj ntu tus lej 222-5917 adapter cable), uas Mingching tau muab cov kev daws teeb meem rau txhua yam khoom.
- Silver{0}}plated Copper Adapter
Cov neeg siv khoom tau teev tseg tias lub adapter yuav tsum siv nyiaj -plated tooj liab es tsis txhob tin -plated tooj. Yog vim li cas: Siab - zaus pulse signals pom cov tawv nqaij; nyiaj hluav taws xob conductivity (63 × 10⁶ S / m) tshaj li ntawm cov tin (9.17 × 10⁶ S / m), thiab cov nyiaj plating muaj qhov zoo tshaj corrosion kuj piv rau tin plating. Nyob rau hauv lub cav compartment cov leej faj- nplua nuj, siab{10}} kub, thiab siab - av noo ib puag ncig, tin plating yuav ua tau ib tug oxide zaj duab xis nyob rau hauv 30 hnub, nce qhov kev tiv thaiv los ntawm tus nqi pib ntawm 0.5 mΩ mus rau ntau tshaj 10 mΩ, uas ua rau cov roj txhaj tshuaj ntau dhau voltage poob.
Mingching Solution:Muab nyiaj-plated tooj liab injector thaiv nrog nyiaj plating thickness Ntau dua los yog sib npaug li 2.5 μm; Tom qab 48-teev nruab nrab ntsev tsuag tshuaj ntsuam ib tus qauv ASTM B700, qhov kev sib cuag tiv thaiv yuav tsum tsawg dua lossis sib npaug li 5%. Lub adapter qhov ntxig thiab tshem tawm quab yuam yog tswj los ntawm 20 N thiab 45 N kom ntseeg tau tias kev sib txuas ruaj khov rau cov twj tso kua mis injector.
2.Terminal Crimping txheej txheem
Crimping zoo yog tus cwj pwm los ntawm crimp qhov siab (CH), crimp dav (CW), thiab tensile quab yuam. Cov neeg siv khoom siv ua haujlwm xyoo- puag ncig hauv kev vibration accelerations ntawm 2-5 g (txog 10 g nyob rau hauv rauj tsav tsheb). Cov pa crimping tuaj yeem pom cov micro- hnav tom qab 200 teev ntawm kev co, nrog kev tiv thaiv kev tiv thaiv nce mus rau ntau tshaj tsib npaug ntawm tus nqi pib.
Mingching Solution: Lub tshuab ua haujlwm puv servo crimping yog ua haujlwm, nrog CCD tshuaj xyuas kom ntseeg tau tias crimp symmetry rau txhua lub davhlau ya nyob twg. Ua raws li IPC/WHMA-A-620 Chav Kawm 3: -Rau 26 AWG cables: crimping tensile force Ntau dua lossis sib npaug li 8.5 lbf; crimp tsis kam Tsawg dua los yog sib npaug rau 1 mΩ. -Peb cov qauv raug xaiv xaiv ib pawg rau 10–500 Hz zaus- cheb kev co (amplitude 1.5 mm, 2 teev ib axis), nrog rau kev vibration tensile quab yuam tsawg dua los yog sib npaug rau 15%.
3. High-kub resistant hlau hlua
Qhov ntsuas kub nyob ze ntawm C7 lub tog raj kheej lub taub hau yog li ntawm 125℃mus rau 150 degree, hos cov pa PVC rwb thaiv tsev tsuas tuaj yeem tiv taus kev siv tas li ntawm 80 degree. Thermal aging ua rau rwb thaiv tsev shrinkage thiab hardening, ua rau inter-wire luv circuits los yog av to.
Mingching tov:Siv ntoo khaub lig- txuas polyethylene (XLPE) lossis fluoroplastic (ETFE) rwb thaiv tsev nrog qhov ntsuas kub ntawm-40℃txog 150℃. Tom qab 3,000 teev ntawm thermal aging (150 degree) rau ISO 6722, lub tensile lub zog tuav tus nqi yuav tsum siab tshaj los yog sib npaug rau 75% thiab elongation tuav tus nqi siab tshaj los yog sib npaug rau 70%. Cov hlua hlau sab nraud yuav tsum tiv thaiv cov roj cav, roj av, thiab cov dej txias (ib SAE J2260).
4.Brand-tshiab, thawj zoo thiab ntim
Cov neeg siv khoom tsis lees txais cov khoom siv kho dua tshiab vim muaj peev xwm hnav ntawm cov khoom siv kho kom rov qab kho dua tshiab thiab zais micro- tawg ntawm cov ntsiab lus crimping.
Mingching txoj kev daws teeb meem:Muab CAT lub cav hloov qhov chaw, tag nrho cov ntaub ntawv 100% tshiab tsim. Factory xeem suav nrog: 100% conduction (plaub-wire millimeter-ohm meter, pib 0.5Ω), rwb thaiv tsev tsis kam (500V DC, Ntau tshaj lossis sib npaug rau 100MΩ), thiab dielectric zog (500V AC / 1min, leakage tam sim no tsawg dua los yog sib npaug). Ntim nta ESD-cov hnab shielded (nto tiv taus<1×10⁹Ω) with vacuum heat sealing, an internal humidity indicator card (RH <30%), and an external box labeled with batch number and test data QR codes.
Kev ua tau zoo Specifications thiab Application Requirements
Rau CAT C7 lub cav, qhov kev ua haujlwm tam sim no rau cov roj injector solenoid li qub yog li ntawm 8 txog 15 A, nrog lub sijhawm nce siab tsawg dua lossis sib npaug li 50 μs. Yog tias tag nrho cov kev tiv thaiv ntawm cov hlua hlau (xws li adapter tiv thaiv kev tiv thaiv, hlau tsis kam, thiab crimping resistance) ntau tshaj 0.5 Ω, nws yuav ua rau lub injector qhib ncua ntev tshaj 100 μs, ua rau lub voj voog roj txhaj tshuaj sib txawv ntawm ± 5% lossis ntau dua. Lub ECU saib xyuas cov tshuaj tiv thaiv lub siab tshaj plaws tam sim no thiab tuav tam sim no los ntsuas kev noj qab haus huv ntawm cov hlua; Thaum kuaj pom qhov txawv txav, nws ua rau muaj qhov yuam kev thiab txwv lub cav torque (txo nws qis dua 60% ntawm tus nqi ntsuas). Yog li ntawd, cov neeg siv khoom xav tau nruj me ntsis rau cov nyiaj{11}}plated tooj liab adapters, precision crimping, thiab tshav kub{12}} cov ntaub ntawv tiv taus ncaj qha cuam tshuam rau lub tshuab hluav taws xob hluav taws xob hluav taws xob, kev ua raws li emissions, thiab cov khoom muaj.
