Patch Cord Production Process Overview
Patch cords yog cov xov hlau luv luv siv rau kev sib txuas hauv Circuit Court hauv cov khoom siv hluav taws xob. Lawv cov txheej txheem tsim khoom yuav tsum sib npaug precision thiab kev ntseeg tau. Ib txheej txheem ib txwm muaj cov theem hauv qab no:
1. Raw Material Preparation: High-purity tooj liab (purity Ntau dua lossis sib npaug li 99.9%) lossis tin-plated tooj liab raug xaiv los ua tus neeg xyuas pib. Cov txheej rwb thaiv tsev feem ntau siv PVC, PE, lossis silicone, nrog rau qhov kub thiab txias ntawm -40℃txog 105℃(saib rau tus qauv thoob ntiaj teb IEC 60227).
2. Conductor Processing: Cov khoom siv tooj liab yog compressed rau lub hom phiaj txoj kab uas hla (piv txwv li, 0.5mm ± 0.02mm) los ntawm cov txheej txheem kos duab, ua raws li annealing los txhim kho yooj.
3. Rwb thaiv tsev txheej Extrusion: Lub siab -kub extruder yog siv los sib npaug ntawm tus neeg xyuas pib nrog cov khoom siv insulating. Lub thickness yuam kev yuav tsum tau tswj nyob rau hauv ± 0.1 hli.
Kev piav qhia ntxaws txog cov txheej txheem ntau lawm
Conductor Manufacturing
- Hlau Drawing: Cov pas nrig tooj liab yog ncab mus rau lub hom phiaj txoj kab uas hla los ntawm ntau qhov tuag. Txhua qhov ncab txo txoj kab uas hla los ntawm kwv yees li 20%, ua tiav txoj kab kawg qhov tseeb ntawm ± 0.01mm.
- Annealing: Cua sov ntawm 400℃-600℃nyob rau hauv ib puag ncig tiv thaiv roj tshem tawm cov kev ntxhov siab sab hauv thiab ua kom cov conductivity mus rau 101% IACS (International Standard for Annealed Copper).
Rwb thaiv tsev txheej txheej
1. Extrusion Parameters: Kub tswj cheeb tsam, piv txwv li, PVC khoom melts ntawm 160℃-180 degree, ntsia hlau ceev 20-40 rpm.
2. Txias thiab Shaping: Dej da dej txias npaum li cas yuav tsum tau khaws cia ntawm 2m / min kom tsis txhob muaj cua npuas los yog deformation.
Kev sib dhos thiab kev sim
- Terminal Crimping: Siv lub tshuab pneumatic crimping, siab ntau 5-10kN, kom ntseeg tau tiv thaiv<10mΩ.
- Kev Ntsuas Hluav Taws Xob: 100% kev tshuaj xyuas ntawm cov hluav taws xob tiv thaiv (piv txwv li, 500V AC / 1 feeb) thiab conductivity; qhov tsis xws luag yuav tsum tsawg dua 0.1%.
Kev Tswj Xyuas Zoo thiab Kev Lag Luam Cov Qauv
1. Dimensional Tolerances: Conductor txoj kab uas hla, rwb thaiv tsev thickness, thiab lwm yam., yuav tsum ua raws li UL758 los yog GB/T 5023 qauv.
2. Ib puag ncig yuav tsum tau ua: Ua raws li RoHS cov lus qhia, txwv tsis pub cov ntsiab lus ntawm 6 yam phom sij xws li txhuas thiab cadmium (piv txwv li, txhuas<0.1%).
Tej teeb meem thiab kev daws teeb meem
- Txheej txheej rwb thaiv tsev puas: Optimized extrusion kub thiab pwm tsim tuaj yeem txo qhov kev puas tsuaj rau qis dua 0.05%.
- Terminal detachment: Tensile testing (Ntau dua lossis sib npaug li 50N) yog siv los tshuaj xyuas cov khoom tsis raug.
