Tus neeg xyuas pib tsis yog "Ib Leeg Hlau" - Nws yog ua los ntawm ntau yam Ultra-Zoo tooj liab Strands
Yog tias koj tau txiav qhib ib qho hluav taws xob hauv tsev zoo tib yam, tej zaum koj yuav pomib qho khoom siv tooj liab- nruj thiab tawv, thiab tej zaum yuav tawg tom qab khoov ob peb zaug.
Tab sis tus neeg xyuas pib siv nyob rau hauv siab -zoo kuaj kab mob sib dhos yogtxawv kiag li.
Nws tsis yog "ib qho khoom siv hlau"; Hloov chaw, nws muaj ntau yam ultra- tooj liab zoo sib tw ua ke-zoo li braiding hlua.
Ib tug tuab tooj liab hlau yog hloov los ntawm kaum los yog txawm pua puazoo heev tooj liab strands. Txoj kab uas hla ntawm txhua tus strand yog feem ntau tsawg dua 0.2 hli, thaum siab - cov cables zoo siv tau cov hlua zoo li0.05-0.10 hli. Cov strands no cesspirally twistedua ke los tsim ib tug multi-strand conductor.
Qhov kev tsim "braided" no daws ib qho teeb meem tseem ceeb: hloov tau yooj yim.
Thaum cov khoom siv tooj liab yog khoov, sab nraud yog ncab thaum sab hauv yog compressed, ua rau muaj kev ntxhov siab kom mloog zoo ntawm qhov khoov taw tes -tom qab rov khoov dua, cov hlau tuaj yeem tawg thaum kawg.
Nrog ntau qhov zoo tooj liab strands twisted ua ke, txhua tus neeg strandtuaj yeem txav me ntsis txheeb ze rau lwm tusthaum khoov. Cov rog sab nraud raug faib thoob plaws ib tus neeg cov strands es tsis txhob muaj kev sib koom ua ke hauv ib lub xov tooj tooj liab tuab.
Nws zoo li kev sib piv ib nras ntawm cov chopsticks nrog ib tug chopstick:ib tug chopstick yooj yim tuaj yeem snap thaum khoov, thaum ib pob ntawm cov chopsticks nyuaj dua. Tib txoj cai siv tau rau ntau -strand zoo tooj liab conductors:qhov ntau strands muaj thiab qhov zoo dua lawv, qhov softer thiab qaug zog ntau dua -resistant tag nrho cable yuav.
Cov ntaub ntawv soj ntsuam kev lag luam kom meej meej qhia qhov txawv:
Siab -kev yooj yim rub- saw cablessiv ntau-strand, ultra-fine, finely stranded oxygen-dawb tooj liab conductors uas ua raws liChav kawm 6 tus neeg xyuas pib raws li DIN VDE 0295 lossis IEC 60288. Hauv10 lab khoov cycles, tus nqi tawg ntawm ntau -strand tooj liab conductors yogntau tshaj 90% qis dua li cov neeg xyuas pib nruj.
Rigid -cov kab hluav taws xobtuaj yeem pib ntsib txoj hlua tawg tom qab xwb5 lab khoov voj voog.
Conductors siv0.08 / 0.10 / 0.12 mm ultra - zoo tooj liab strandstuaj yeem tiv taustsawg kawg yog 1 lab reciprocating bending cyclesntawm tus qauv dabtsi yog khoov vojvoog ntawm 7.5 npaug ntawm cov kab hluav taws xob sab nraud, tsis muaj cov hlua tawg lossis cov rwb thaiv tsev tawg.
Siab dua - cov khoom tshwj xeeb tuaj yeem ua tiav lub neej khoov ntawm6-8 lab lub voj voog, lossis txawm tias 20 lab lub voj voog.
Qhov zoo dua cov tooj liab strands, ntau dua cov strands, thiab qhov luv ntawm cov hlua khi, qhov softer thiab khoov ntau dua - tiv thaiv lub cable.Qhov no yog vim li cas lub siab -kev kuaj kab mob zoo tuaj yeem rov coiled, khoov, thiab khaws ciatsis muaj internal core breakage.
Lub tsho Elastomer muab "Tus Kheej-Rov qab"
Tus neeg xyuas pib muabyooj, tab sis yooj yim ib leeg tsis txaus. Ib lub cable kuj xav tau lub peev xwmrov qab mus rau nws qhov qub qub tom qab khoov.
Qhov no yog qhov twgelastomer tsholos nyob rau hauv.
PUR (polyurethane)yog athermoplastic elastomernrog ib tug tshwj xeeb molecular qauv muaj xws li alternatingntu nyuajthiabntu mos.
Cov ntu nyuaj muab lub zog thiab kev puas tsuaj, thaum cov ntu mos muab kev yooj yim thiab elastic rov qab.
Thaum lub cable yog khoov,cov saw hlau molecular nyob rau hauv cov ntu mos tig thiab ncab kom nqus tau lub zog deformation. Thaum lub zog sab nraud raug tshem tawm,cov ntu nyuaj ua zoo li cov springs, rub lub molecular chains rov qab mus rau lawv cov haujlwm qub.
Tiag -cov ntaub ntawv xeem thoob ntiaj teb ua rau qhov sib txawv txawm tias pom tseeb dua:
PUR tsho tuaj yeem ua tiav ib qhoelongation ntawm tawg mus txog 400%, deb tshaj qhov kwv yees150%ib txwm ntawm cov khoom siv PVC.
Tom qab rov khoov dua, PUR tuaj yeem tuav tau arebound tus nqi ntau dua 95%.
Nyob rau hauv standard abrasion xeem raws liTS EN ISO 4649 Cov, PUR nthuav tawm antau qis ntim poob vim kev puas tsuajdua li cov khoom siv PVC thiab roj hmab.
Cias muab,lub tsho PUR zoo li lub siab - cov roj hmab zoo: ncab nws thiab nws elongates; tso nws thiab nws rov qab los. Qhov no "tus kheej- rov qab" muaj peev xwm ua kom ntseeg tau tias lub cabletsis tsim deformation mus tas lithaum rov khoov, thaum lub tsho sab nrauvtsis wrinkle, bulge, los yog tawg.

Yuav ua li cas lub "SR Strain-Relief Boot" Hloov Pulling Force mus rau lub vaj tse hloov ntawm Internal Solder Joints
Tus neeg xyuas pib hloov tau yooj yim thiab lub tsho elastic yog qhov tseem ceeb -tab sis qhov chaw ntawm lub cable uas muaj feem cuam tshuam rau kev ua tsis tiav yog qhov tseebtsis nyob hauv nruab nrab, tab sis ntawm ob qhov kawg.
Kev sib txuas ntawm covOBD connector thiab cableyog qhov hloov pauv ntawm arigid tivthaiv (lub connector)thiab aFlexible Cheebtsam (lub cable).
Txhua lub sij hawm lub connector yog ntsaws rau hauv los yog unplugged, los yog txhua zaus lub cable yog rub,lub zog ua kom muaj zog ntawm qhov kev hloov pauv no. Yog tias tsis muaj kev tiv thaiv zoo, cov pob qij txha sab hauv yog pheej rov qab los ntawm cov neeg kho tshuab kev ntxhov siab, nws thiaj li dhau los ua xoob thiabtawg.
Qhov no yog raws nraim qhov teeb meem uas SR (Strain Relief) khau raj tsim los daws.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm SR strain- nyem khau raj yog qhov ntse heev: nws tsis ua rau lub cable " dais" lub zog rub; Hloov chaw, nws ua rau lub zog rub "bypass" cov pob qij txha sab hauv.
Thaum lub zog sab nraud rub ntawm lub cable, SR khau raj -ib tug elastic qauv integrally molded nyob rau hauv lub rear ntawm connector- los ua haujlwm.
Kauj Ruam 1: tuav
SR khau rajnrees tuav lub tsho sab nrauv ntawm lub cable, tawm hauv zoo tsis muaj chaw rau kev txheeb ze.
Yog li ntawd, lub zog rub yog siv rau khau raj es tsis yog ncaj qha mus rau hauv cov pob qij txha sab hauv.
Kauj ruam 2: Hloov
Lub khau rajhloov lub zog rub mus rau lub vaj huam sib luag-txawm yog lub tsev yas lossis cov hlau thaiv lub plhaub- tsis yog hloov nws mus rau cov pob qij txha sab hauv.
Qhov tshwm sim
Thaum koj rub lub cable quab yuam,lub zog-relief khau raj cuam tshuam lub zog, yog li lub internal solder pob qij txhakev paub zoo tsis muaj tensile load.
Qhov kev tsim no siv tau li cas?
Raws li qhov kev ntxhov siab - kev sim ntsuas kev xav tau ntawm cov txheej txheem thoob ntiaj tebIEC 60884-1 Cov, ib tug plug yuav tsum tiv taus a60 N rub quab yuam (kwv yees li 6 kg)siv100 zaus ntawm ib zaus ntawm ib zaug ib ob.
Ib lub cable nruab nrog tsim nyog SR khau raj tuaj yeemyooj yim dhau qhov kev xeem no, nrog rau cov pob qij txha sab hauv uas tsis muaj zog thiab kev ua haujlwm hluav taws xob tsis cuam tshuam.
Yuav ua li cas yog tsis muaj SR khau raj?
Tom qab tsuas yog ob peb lub voj voog rub, cov pob qij txha sab hauv yuav pib xoob, ua rauCov teeb liab tsis sib xws, cuam tshuam ECU programming, thiab thaum kawg yog ib qho tsis siv tau kiag li.

"Qhov kev hloov pauv siab" tsis ua tiav los ntawm ib qho khoom siv lossis ib qho kev tivthaiv - nws yog qhov tshwm sim ntawm kev sib koom tes ntawm cov neeg siv khoom sib txuas tshuab, cov khoom siv hluav taws xob, thiab cov khoom siv sib txuas.
Multi-strand ultra- tooj liab conductorstiv thaiv cov tub ntxhais tawg thaum lub sij hawm tsheej lab ntawm kev khoov mus;PUR elastomer tshotso cai rau lub cable rov qab mus rau nws qhov qub qub tom qab txhua qhov khoov; thiabSR strain-cov khau khau khautiv thaiv cov pob qij txha sab hauv los ntawm cov neeg kho tshuab kev ntxhov siab los ntawm kev rov txuas ntxiv, tshem tawm, thiab rub tawm.
Nws yog kev sib xyaw ua ke ntawm peb txheej tiv thaiv uas tsim kom muaj qhov "siab- yoog raws, rub- tiv taus" kev kuaj kab mob.
Ob lub cables yuav zoo tib yam rau sab nraud, tab sis sab hauv,lawv yuav txawv ntawm peb tiam ntawm engineering technology.
