Cov khoom siv hluav taws xob tshiab hluav taws xob yog cov khoom siv tseem ceeb uas ua kom muaj kev nyab xeeb, ruaj khov, thiab siv hluav taws xob sib kis tau zoo ntawm cov roj teeb, cov khoom siv, thiab cov pob khoom. Lawv yuav tsum tiv taus siab tam sim no (200-800A), high voltage (400-800V), dav kub hloov pauv (-40℃txog 125 degree), thiab muaj zog vibration. Ntawm tag nrho cov txheej txheem tsim khoom,precision stamping, kev ntseeg siab plating, thiab automated vuam / sib dhossawv tawm raws li peb cov txheej txheem tseem ceeb uas ncaj qha txiav txim siab qhov kev sib txuas, kev nyab xeeb, thiab kev pabcuam lub neej.
Precision Stamping: Dimensional Accuracy thiab Structural Strength
Stamping yog thawj thiab tseem ceeb tshaj plaws txheej txheem rau roj teeb connectorcov davhlau ya nyob twgthiab busbars. Nws lub hom phiaj yog los tsim cov khoom siv high-precision conductive nrog geometry zoo ib yam, tsawg deformation, thiab zoo heev mechanical zog.
● Cov khoom xaiv: High-conductivity tooj liab alloys (xws li, C11000, C19400) los yog txhuas alloys feem ntau siv, ntsuas conductivity, lub zog, thiab nqi.
● High-precision tooling: Progressive tuag nrog micron-theem qhov tseeb xyuas kom tiaj tus, ncaj, thiab qhov ntev ntev nyob rau hauv ± 0.02 hli, uas yog qhov tseem ceeb rau kev tiv thaiv qis thiab kev sib raug zoo.
● Cov yam ntxwv tseem ceeb: Elastic contact structures (piv txwv li, ntau qhov chaw sib cuag, cantilever beams) yog thwj rau hauv cov terminals kom ruaj khov kev sib cuag siab nyob rau hauv kev co thiab thermal expansion.
● Kev tswj kom zoo: In-line pom kev soj ntsuam xyuas cov burrs, tawg, thiab qhov tsis zoo; tsuas yog cov khoom tsis muaj qhov tsis zoo mus rau plating.
Yog tsis muaj leej twg stamping, cov khoom sib txuas raug kev txom nyem los ntawm kev sib raug zoo, kev sib cuag tsis zoo, thiab kev ua haujlwm siab, ua rau muaj hluav taws kub, qhov hluav taws xob poob, thiab txawm tias hluav taws kub hnyiab nyob rau hauv siab tam sim no.
High-Reliability Plating: Conductivity, Corrosion Resistance, thiab Contact Stability
Plating yog cov txheej txheem tseem ceeb uas lav qhov kev ua tau zoo ntawm hluav taws xob mus sij hawm ntev thiab ib puag ncig zoo. Cov roj teeb sib txuas ua haujlwm hauv cov xwm txheej hnyav- cov av noo siab, tshuaj tsuag ntsev, thiab kub caij tsheb kauj vab - ua kom plating zoo txiav txim siab rau kev ntseeg tau.
● Plating qauv: Feem ntau ib txheej txheej txheej: puag nickel (2–5 μm) → nruab nrab txheej → txheej txheej.
● Cov ntaub ntawv saum npoo:
Kub (0.01-0.025 μm): Zoo heev conductivity thiab oxidation tsis kam, siv rau high-kev ntseeg siab ntawm cov teeb liab hu (BMS).
Palladium-nickel: Tus nqi qis dua kub, zoo hnav tsis kam, dav siv nyob rau hauv nruab nrab-rau-siab terminals tam sim no.
Tin: Tsawg tus nqi, zoo solderability, tab sis nws yooj yim rau tin whiskers thiab oxidation; Feem ntau yog rau cov neeg siv khoom siv hluav taws xob, tsis tshua muaj nyob rau hauv automotive high-voltage systems.
Cov kev cai tseem ceeb:
🔵 Tsawg tiv thaiv (<0.5 mΩ) to minimize heat at high current.
🔵 Uniform thickness npog tiv thaiv substrate raug thiab corrosion.
🔵Resistance rau thermal cycling (-40℃rau 125 degree) thiab kev co tsis tev lossis tawg.
Kev plating tsis zoo ua rau muaj kev tiv thaiv kev tiv thaiv ntau dua thaum lub sijhawm, hotspots, thiab kev sib txuas tsis tu ncua -qhov laj thawj tseem ceeb ntawm lub roj teeb tsis ua haujlwm.
Automated Welding & Assembly: Hluav taws xob kev ncaj ncees thiab txhua yam muaj zog
Vuam thiab sib dhos ua ke muab cov khoom sib dhos thiab plated rau hauv qhov kawg txuas, ua kom muaj zog hluav taws xob sib txuas, txhim khu kev qha rwb thaiv tsev, thiab kev tiv thaiv zoo. Cov txheej txheem no cuam tshuam ncaj qha rau kev nyab xeeb thiab kav ntev.
Vuam technologies:
● Laser vuam: High precision, tsawg tshav kub input, tsawg deformation; zoo tagnrho rau tooj liab-aluminium dissimilar pob qij txha thiab nyias busbars.
● Ultrasonic vuam: Kev sib koom ua ke ntawm solid-state, tsis muaj melting, tsis muaj zog; dav siv rau kev sib txuas ntawm tes-rau-busbar.
●Resistance vuam: Ceev ceev, tus nqi tsim nyog rau kev tsim khoom loj ntawm cov terminals me.
Cov kauj ruam ua ke:
1.Insert terminals rau hauv insulating vaj tse (high-temperature engineering plastics zoo li PBT lossis PEEK).
2.Install seals (silicone roj hmab) rau IP67 / IP68 waterproofing.
3.Add shielding (tooj liab braid los yog hlau plhaub) rau EMI tiv thaiv nyob rau hauv high-voltage systems.
4.Torque tswj rau bolted kev sib txuas (25-35 Nm) kom ntseeg tau tias muaj kev sib cuag zoo sib xws.
● Kev sim zaum kawg: 100% hluav taws xob (kuj, rwb thaiv tsev, high-voltage withstand), mechanical (vibration, insertion force), thiab ib puag ncig (kub cycling, ntsev tsuag) kev ntsuam xyuas.
Kev sib txuas tsis sib xws lossis kev sib dhos tsis tu ncua ua rau cov pob qij txha tsis muaj zog, kev cuam tshuam ntawm rwb thaiv tsev, lossis thaiv qhov khoob - ua rau muaj kev pheej hmoo loj heev ntawm luv luv Circuit Court, hluav taws xob to, lossis electromagnetic cuam tshuam.
