Ferrule

Ndiye ferrule ndi chiyani?Nthawi zambiri, lamba wamtundu uliwonse kapena kopanira omwe amagwiritsidwa ntchito polumikiza, kulimbikitsa kapena kusungitsa zinthu pamodzi.Ndi tanthauzo lalikulu lomwe limakwirira chilichonse kuyambira zingwe zomangirira mpaka kumapeto kwa zingwe za nsapato kuti zisatseguke, mpaka zolimba zachitsulo. zomwe zimagwiritsidwa ntchito polumikiza zingwe zamawaya palimodzi.Koma m'dziko la waya, ma ferrules ali ndi tanthauzo lapadera ndipo amagwira ntchito yosiyana kwambiri ndi ma ferrules omwe amagwiritsidwa ntchito pongogwiritsa ntchito makina.
Waya ferrule ndi chubu chofewa chachitsulo chomwe chimapindika mpaka kumapeto kwa waya wokhazikika kuti ziwongolere mawonekedwe a mawaya. Ma ferrule ambiri amapangidwa ndi mkuwa, nthawi zambiri amapangidwa ndi malata. ndi kutalika.Komabe, ferrule ndi yoposa silinda yosavuta - imakhala ndi milomo kapena moto pamphepete imodzi yomwe imasonkhanitsa ndikugwirizanitsa chingwe chimodzi cha waya pamene ferrule imayikidwa.
Kutentha kwa ma ferrules ambiri sikumawonekera nthawi yomweyo chifukwa nthawi zambiri amakulungidwa ndi manja a pulasitiki olowera chingwe. Mosiyana ndi zolumikizira zachikhalidwe zachikhalidwe, mkono wa pulasitiki wa ferrule supanikizidwa panthawi yoyika. Imakhalabe bwino mozungulira chotsekera ndipo imapereka mpumulo wopumira pambuyo pakuyika posuntha utali wopindika wa waya kutali ndi kumapeto kwa chotsekera. .Manja ambiri a ferrule ali ndi mtundu wamtundu wa kukula kwa waya mu muyezo wa DIN 46228, womwe, mosokoneza, uli ndi zizindikiro ziwiri zosiyana, French ndi German, mu millimeters lalikulu kwa malo omwewo.
Ngati ferrule ikumveka ngati chinthu cha ku Ulaya kuposa chinthu cha ku America, ndi chifukwa chomveka. Kuti mupeze chiphaso cha CE, zipangizo zamagetsi ziyenera kutseketsa mawaya otsekedwa mu screw kapena masika ndi ferrules. kugwiritsiridwa ntchito kwa ferrules mu zipangizo za US sikofala.Koma ferrules ali ndi maubwino enieni omwe ndi ovuta kukana, ndipo kukhazikitsidwa kwawo kumawoneka kuti kukufalikira chifukwa amapanga nzeru zaumisiri wabwino.
Kuti mumvetse momwe, ikani chingwe chachifupi cha waya wotsekeka wamtundu uliwonse. Waya wokhazikika ndi wosinthika, chomwe ndi chimodzi mwa zifukwa zomwe waya wokhazikika amagwiritsidwa ntchito m'malo mwa waya wolimba pamapulogalamu am'manja komanso kuthekera kwa kugwedezeka. , mwa zina chifukwa chakuti kutchinjiriza kumakulunga zingwe za kondakitala, kuzisunga moyandikana kwambiri ndi kusunga chingwe cha munthu payekha chopotoka kapena choyala. Zingwe zimasokonekera pang'ono - zimamasula pang'ono. Chotsani zotsekera kwambiri ndipo zingwezo zimalekanitsidwa kwambiri. Chotsani zotchingira zonse ndipo ma conductor adzataya kusakhulupirika kwa kapangidwe kake ndikugwera mumingwe iliyonse.
Ili ndi vuto lalikulu lomwe ma ferrules amathetsa: Akavula, amasunga mgwirizano wolimba pakati pa zingwe za kokitala ndikulola kuti kulumikizana kuyendetse nthawi yake yonse. za chingwe chimodzi chomwe chimalumikizana molimba ndi terminal. Kuthaku kumakhala ndi kukana kwakukulu kuposa kulumikizana koyenera kwa ferrule.Kugwira ntchito kwa mawaya omangika okhala ndi ma ferrules ndikwabwino kwambiri kuposa opanda ma ferrules.Source: Weidmüller Interface GmbH & Co.

Malata siolimba kwenikweni, koma amapunduka pakapita nthawi.Chotsatira chake, zolumikizira zomwe zidalimbitsidwa pakukhazikitsa zimatha kumasuka pakapita nthawi.kulumikizana kotayirira -> kukana kwambiri -> kutentha kwambiri -> malata olimba -> kulumikizana kotayirira…mukudziwa chikuchitika ndi chiani
Komanso malata amatha kulowa m'malo otchingira ndi kupanga malo olimba kwinakwake kutali ndi cholumikizira - ngati mulibe mwayi, apa ndipamene zingwe za waya zimayamba kuduka, ndikupangitsa zolakwika zosawoneka.
Vuto lalikulu, kuphatikiza kuti malata kapena zosakaniza za malata + ochiritsira ndizofewa kwambiri, malata "ozizira" amatuluka mu screw kudzera pa njinga yamoto komanso kupsinjika, posakhalitsa kumayambitsa kukana kukhudzana.
Chifukwa chachitatu chomwe ndamva motsutsana ndi soldering ndikuti solder ndi yofewa kwambiri ndipo pakapita nthawi maulumikizidwe a screw amamasuka.
Kuzizira kozizira pansi pa kupanikizika ndi chifukwa chomwecho kuti zingwe zakale za aluminiyamu zimakhala zoopsa kwambiri.Pakapita nthawi, maulumikizidwe amakhala omasuka, kukana kumakwera + kugwirizana kosauka kungayambitse arcing.
Sindimakonda kuyipeza pa site.Solder ndi yolimba komanso yosalala, kotero kuti chipikacho sichimangirira ndikugwirapo ngati copper.Ferrule crimpers imayika ma serrations pa crimp, kotero imagwira bwino kuposa solder.
Waya wothira pazitsulo zomangira ndi lingaliro loipa chifukwa ngakhale kutentha kwa firiji solder imasuntha pang'ono pansi pa kukanikiza ndipo pamene kutentha kumayendetsedwa ndi njinga, kumatuluka mu mgwirizano ndikuchepetsa malo olumikizana ndikuwonjezera kukana, motero kutenthetsa, zomwe zimapangitsa ndemanga zabwino zotsatira.
Kupaka malata ndikofewa kuposa mkuwa wopanda kanthu. Zotsatira zake, zomangira zimatha kutaya pakapita nthawi mwachangu kuposa ma ferrules kapena lugs.
Ndikudziwa kuti ku Europe, mawaya osokonekera nthawi zambiri amamangidwa zida zambiri zisanathe kapena kuwotcha, ndipo crimping tsopano ndi vuto.
Zimayambitsa vuto pakuchepetsa nkhawa…nthawi zambiri zimasweka pomwe solder imathera, chifukwa imalola kupindika kwambiri (mawaya ogulitsidwa ndi olimba, mawaya osagulitsidwa si….
Sindinganene kuti waya wa soldering.makamaka ngati pali kugwedezeka kapena kusuntha, chingwe chanu chikhoza kuthyoka pakanthawi kochepa.
