Cov qauv thiab cov kev qhia tshwj xeeb ntawm lub tsheb ntsuas kev coj ua (cov xaim lossis cov hlua txuas txuas lub ntsuas hluav taws xob rau ntau lub sensors thiab tswj lub tsheb) yuav tsum tau txiav txim siab raws li lub tsheb hom, ntsuas kev ua haujlwm, hluav taws xob tsis zoo, thiab cov qauv kev lag luam. Cov specifications txawv heev nyob rau hauv txawv scenarios. Cov hauv qab no yog cov qauv kev qhia tshwj xeeb kev faib tawm thiab kev piav qhia:
1.Wire khoom thiab rwb thaiv tsev txheej hom
(1) Cov khoom siv hlau
Lub ntsiab yog tooj liab tub ntxhais hlau (ntshiab tooj liab los yog siab -purity electrolytic tooj liab) nrog zoo conductivity; Qee qhov chaw siab - qhov kub thiab txias (xws li cov coj nyob ze ntawm lub cav cav) yuav siv cov tin plated tooj liab cores los txhim kho corrosion kuj thiab oxidation tsis kam.
Cov xwm txheej tshwj xeeb (xws li cov tsheb uas xav tau lub teeb hnyav) tuaj yeem siv tooj liab-clad txhuas hlau, tab sis nws cov conductivity qis dua thiab nws daim ntawv thov raug txwv.
(2) Cov khoom siv rwb thaiv tsev
Ib puag ncig zoo:PVC(polyvinyl chloride), tus nqi qis, zoo rwb thaiv tsev, haum rau ib puag ncig kub nyob rau hauv lub cockpit (-40℃~ 125 degree).
Qhov kub thiab txias ib puag ncig (xws li ze ntawm lub cav lossis cov yeeb nkab tso pa):XLPE(cross-txuas polyethylene) lossis silicone roj hmab, nrog rau qhov kub thiab txias ntawm -60℃~ 150℃lossis siab dua.
Hnav resistant / roj resistant scenarios: chloroprene roj hmab ({2}} 60℃~ 125℃), cross-linked fluororubber (-60℃~ 200 degree) los yog polytetrafluoroethylene (PTFE) (-60℃~ 260 degree), haum rau thaj chaw sib cuag nrog cov roj cav thiab roj.
2.Wire cross-sectional area (wire diameter) specification
Hlau txoj kab uas hla yog ib tug tseem ceeb parameter txiav txim los ntawm lub tam sim no hla dhau, xaim ntev, thiab tso cai voltage poob, feem ntau ntsuas nyob rau hauv square millimeters (mm2) los yog American Wire Gauge (AWG).
Cov teeb liab me me tam sim no ua rau (xws li ceev, dej kub, thiab roj theem sensor teeb liab kis tau tus mob): Tus ntoo khaub lig- cheeb tsam feem ntau yog 0.3mm2 ~ 0.75mm2 (xws li AWG 22 ~ 18), thiab tam sim no feem ntau tsawg dua los yog sib npaug rau 1A.
Nruab nrab tam sim no coj (xws li ntsuas backlight thiab qhov taw qhia lub teeb fais fab kab): nrog tus ntoo khaub lig-sectional cheeb tsam ntawm 0.75mm2 ~ 1.5mm2 (AWG 18 ~ 16) thiab tam sim no ntawm 1A ~ 5A.
High tam sim no leads (xws li ntsuas fais fab mov lub ntsiab kab, cua sov ua hauj lwm leads): cross-sectional cheeb tsam muaj peev xwm ncav cuag 2.5mm2 ~ 4mm2 (AWG 14 ~ 12), tam sim no 5A ~ 10A (nyob ntawm seb lub hwj chim xam, loj hlau txoj kab uas hla yuav tsum tau rau cov ntsuas cua sov hlau fais fab mov).
3. Hlau xim thiab kev qhia
Rau kev yooj yim ntawm kev teeb tsa thiab kev saib xyuas, cov xim txhuas yuav tsum ua raws li cov qauv kev lag luam (xws li ISO, SAE, lossis kev cai tshwj xeeb ntawm cov tuam txhab tsheb). Hom xim thiab lub ntsiab lus:
Cov ncej zoo ntawm lub hwj huam mov: Liab, Xim av
Tsis zoo/Grounding: Dub, Grey
Cov kab hluav taws xob kis tau tus mob: daj, ntsuab, xiav (feem ntau nrog kab txaij, xws li daj / dub, ntsuab / dawb, kom paub qhov txawv hom teeb liab, xws li teeb liab ceev, dej kub teeb liab).
4.Wire harness qauv thiab kev tiv thaiv specifications
(1) Ib qho tseem ceeb thiab ntau-core
Cov cuab yeej siv feem ntau yog cov tub ntxhais ib leeg (ib leeg lossis ntau txoj hlua khi), thaum cov xov hlau sib txuas (xws li 7-stranded 0.16mm tooj liab hlau) muaj qhov yooj yim dua thiab haum rau cov cheeb tsam uas muaj kev vibrations nquag.
Cov teeb liab ua ke ib nrab tuaj yeem siv ntau- cov tub ntxhais tiv thaiv cov xov hlau (xws li nrog aluminium foil thiab braided mesh shielding txheej) los tiv thaiv electromagnetic cuam tshuam (EMI) thiab tsis txhob cuam tshuam nrog cov cim qhia meej xws li kev ceev thiab tsheb ceev.
(2) Hlau hlua tiv thaiv
Cov yeeb yaj kiab tuaj yeem raug them nrog cov kav dej corrugated (PP lossis PA cov ntaub ntawv) lossis cov hlua khi hlua los txhim kho kev hnav tsis kam thiab khoov tsis kam.
Cov hlau lead uas dhau los ntawm lub qhov hlau yuav tsum tau tiv thaiv nrog cov roj hmab sheath kom tiv thaiv cov txheej rwb thaiv tsev los ntawm kev txiav los ntawm cov npoo ntse.
5.Industry qauv thiab cov qauv qhia
(1) Cov txheej txheem thoob ntiaj teb
Ua raws li ISO 16942 (Txoj Kev Tsheb - Tsawg Voltage Cables) lossis SAE J1128 (Automotive Electrical Wiring), tus qauv qhia txog qhov ntsuas kub tsis kam (xws li 105 degree, 125 degree) thiab kev ua haujlwm voltage (feem ntau ntau dua lossis sib npaug ntawm 300V. AC)
Model ID: "FLRY-B0.5mm2" (FLRY yog cov cai rau tsheb qis-voltage xov hlau, B sawv cev rau nyias- phab ntsa rwb thaiv tsev, thiab 0.5mm2 yog tus ntoo khaub lig- ntu ntu).
(2) Customized specifications rau tsheb manufacturers
Cov tuam txhab tsheb sib txawv (xws li Toyota thiab Volkswagen) yuav tsim cov kev qhia sab hauv raws li cov qauv thoob ntiaj teb, xws li hlau xim coding, shielding txheej thickness, thiab lwm yam. Cov qauv tshwj xeeb yuav tsum tau xa mus rau kev saib xyuas phau ntawv ntawm cov qauv sib xws (xws li Volkswagen's "VW 60306" tus qauv).
6.Piv txwv ntawm daim ntawv thov scenarios
Lub tsheb ntsuas lub teeb liab hlau: feem ntau 0.3mm2 ~ 0.5mm2 ib leeg tub ntxhais PVC insulated hlau, nrog kab txaij xim (xws li ntsuab / daj rau lub teeb liab ceev), ua raws li ISO 16942 Class B (nyias-walled).
Kev lag luam tsheb ntsuas hluav taws xob qaum: Vim muaj qhov siab tam sim no (xws li ntsuas backlight + sensor fais fab mov), 1.0mm2-1.5mm2 tinned tooj liab tub ntxhais hlau nrog rwb thaiv tsev txheej kub ntawm 105℃yuav siv tau.
Tshiab lub zog tsheb ntsuas siab -voltage teeb liab lead: Nws yuav tsum tau ua kom tau raws li qhov siab ntxiv -voltage rwb thaiv tsev qauv (xws li UL 94 V-}0 nplaim hluav taws retardant rating), nrog ib tug ntoo khaub lig-sectional cheeb tsam txog li 2.5mm2 los yog ntau tshaj thiab ib tug ob chav shielding txheej.
Hauv luv luv, tsis muaj kev sib koom ua ke "tus nqi ruaj khov" rau cov qauv kev qhia tshwj xeeb ntawm cov cuab yeej siv tsheb, uas yuav tsum tau txiav txim siab raws li cov qauv hluav taws xob tsim hluav taws xob lossis phau ntawv saib xyuas ntawm cov qauv tsheb tshwj xeeb. Yog tias xav tau kev yuav khoom lossis hloov pauv, nws raug nquahu kom xa mus rau cov lej muab los ntawm cov chaw tsim khoom tsheb (xws li Bosch, Continental's instrument harness naj npawb) lossis cov tsis muaj nyob rau ntawm kev txheeb xyuas cov xaim (hla - cheeb tsam, qhov ntsuas kub, thiab lwm yam).
